Introduction to Electric Servo Press
Definition of Electric Servo Press
The Electric Servo Press is a type of press whose pressure system is composed of components such as an electric motor, servo motor driver, sensor, pressure valve, etc. Compared to traditional hydraulic presses, the Electric Servo Press does not require a hydraulic system, oil circuit, or hydraulic oil. Instead, it drives the movement of the lower die through the motor and control system, and monitors pressure changes in real-time through a pressure sensor, which is then regulated by a pressure valve to achieve the desired pressure value and stability requirements.
Structurally, the Electric Servo Press typically consists of a frame, upper and lower platens, electric motor, servo motor driver, pressure sensor, pressure valve, control system, and other components. The frame serves as the main supporting part, used to carry and fix other components. The upper and lower platens are used to clamp and process the workpiece. The electric motor and servo motor driver serve as power sources to drive the movement of the lower platen. The pressure sensor is used to monitor pressure changes in real-time and feed signals back to the control system. The pressure valve adjusts the pressure size and stability by controlling the flow rate of the oil circuit. The control system is used to monitor and control the entire press's operating status, including functions such as setting pressure values, operating time, safety protection, and more.
Electric Servo Press's features and advantages are mainly manifested in the following aspects:

The development history of electric servo presses
The development of traditional mechanical presses
Mechanical press is an important equipment in the mechanical manufacturing industry, which is used for forming and processing metal materials. Its working principle is to apply pressure by driving the mechanical system, so that the metal material undergoes plastic deformation or cutting and shearing processing, thus realizing the processing and manufacturing of various parts. In the history of the development of mechanical presses, traditional mechanical presses are the earliest and most basic form.
The history of traditional mechanical presses can be traced back to the Industrial Revolution in the late 18th century. At that time, due to the low efficiency of manual labor, the demand for mechanized production continued to increase. Mechanical presses gradually developed under this demand. The earliest mechanical presses were based on human or steam power, and were mainly used for rough metalworking such as forging, die casting, and stamping.
In the mid-19th century, with the gradual development and maturity of electric power and hydraulic technology, mechanical presses began to gradually realize automated and semi-automated production, and traditional mechanical presses were further developed and improved. During this period, a slide-type press with a power transmission system was invented, which used a clutch and brake device to achieve rapid stopping and automatic adjustment, greatly improving production efficiency and processing accuracy. At the same time, the emergence of hydraulic presses injected new vitality into the development of mechanical presses.

Components of Electric Servo Press
The electric servo press uses a motor and control system to drive the movement of the lower mold, without the need for a hydraulic system, oil circuit, or hydraulic oil. It has the advantages of high precision, fast response speed, low noise, and low energy consumption.
The motor drive system of the electric servo press is the core part for implementing the movement of the lower mold. Its function is to convert electrical energy into mechanical energy, and control the speed, position, and force of mechanical movement. This system is usually composed of a servo motor, servo reducer, servo transmission device, and servo controller. The following is a detailed introduction to the structure of the electric servo press:
Servo Motor
The servo motor is the power source of the electric servo press system, and its speed and torque directly affect the efficiency and precision of the machine. Servo motors usually use AC or DC motors. AC motors have high torque and power factor, but their control is complex. DC motors have simple control and fast response, but require regular maintenance of brushes and commutators. The power of the motor is selected according to the specifications and requirements of the press. Typically, the electric servo press uses a brushless DC motor or AC servo motor.
AC Motor
The servo motor is a motor that can perform precise position control based on a control signal. Its controller usually consists of a position feedback device, a controller, and a power amplifier. The position feedback device is used to measure the actual position of the motor. The controller calculates the control signal of the motor based on the set value and feedback information. The power amplifier converts the control signal into the motor's power output. The advantage of the servo motor is that it can achieve high-speed and high-precision control, and is suitable for applications that require high-speed and high-precision positioning.
Compared with traditional AC asynchronous motors, servo motors have the following advantages:
Wide speed range: Servo motors have a high speed range and can flexibly switch between high-speed motion and low-speed positioning to meet the needs of different working conditions.
Good low-speed performance: Servo motors can maintain a high torque output at extremely low speeds, which can meet the requirements of low-speed positioning and high rotational accuracy.
Fast response: The controller of a servo motor can quickly respond to control signals, achieve high-speed precision control, and respond faster than traditional AC asynchronous motors.
High precision: Servo motors can achieve precise position control by feeding back actual position information to the controller through a position feedback device, meeting the requirements of high-precision machining and control.
DC motor (Stepper motor)
A stepper motor is a type of motor that uses open-loop control to control the motor's rotational steps by controlling the number and frequency of electrical pulses, thereby achieving position control. The controller for a stepper motor typically includes a driver, a controller, and a position feedback device. The driver converts the control signal into electrical pulse signals, the controller calculates the actual position of the motor based on the pulse signals and the position feedback signal, and the position feedback device measures the actual position information of the motor. The advantages of stepper motors are high positioning accuracy and response speed, making them suitable for applications with high requirements for positioning accuracy and speed.
Compared to traditional DC motors, stepper motors have the following advantages:
High positioning accuracy: Stepper motors use open-loop control to control the motor's rotational steps by controlling the number and frequency of electrical pulses, which can achieve higher positioning accuracy.
Simple structure: The structure of stepper motors is relatively simple, consisting of a motor and a controller. Compared to traditional motors, they are more compact and suitable for applications with limited space.
Low energy consumption: Stepper motors do not consume energy when in a static state and only require power when working, which can effectively reduce energy consumption.
Low noise: Stepper motors operate with low noise, making them suitable for applications with high noise requirements.
The controller for a servo motor typically includes position feedback devices, controllers, power amplifiers, etc., used to achieve precise control of the motor. On the other hand, the controller for a stepper motor typically includes a driver, controller, and position feedback device, used to achieve positioning and control of the motor.
Servo Motor Reducer
In an electric servo press, the role of the reducer is to convert the high-speed low-torque output of the motor to low-speed high-torque output, enabling the press to achieve precise pressure and speed control. The reducer typically consists of a gearbox, bearings, and transmission components. The following will provide a detailed introduction to the construction and working principle of the reducer in an electric servo press.
Planetary Gear Reducer
Planetary gear reducer is a commonly used high-precision reducer, consisting of internal, external, and planetary gears. The planetary gears are connected to the internal gears through a planetary gear carrier, while the external gears are connected to the output shaft of the reducer. The rotation of the planetary gears causes the internal and external gears to rotate, thereby achieving speed reduction. Planetary gear reducers have the advantages of high precision, high rigidity, and low noise, and are widely used in the field of industrial automation control.
Worm Gear Reducer
Worm gear reducer is a simple structured, high-efficiency, and strong load capacity reducer, suitable for low-speed and high-torque applications. The worm gear reducer consists of a worm, a worm wheel, an output shaft, etc., and achieves speed reduction through the friction between the worm and worm wheel. The angle of the worm wheel is about 20 degrees, which is the same as the helix angle of the worm, forming a helical gear pair. The rotation of the worm makes the worm wheel produce friction, thereby achieving speed reduction.
Gear Reducer
Gear reducer consists of a set of gears, achieving speed reduction through the meshing between the gears. Gear reducers have a simple structure, but require high precision in the meshing between gears, so they need to be kept clean and lubricated during use.
Series Gear Reducers
Series gear reducers are a reduction system composed of multiple reducers in series. In electric servo presses, series gear reducers are often used to achieve higher reduction ratios and higher torque output. Each level of the series gear reducer provides partial reduction ratio, and the final reduction ratio is the product of all the levels' reduction ratios.
Overall, the gear reducer of an electric servo press needs to be selected and optimized according to the actual application scenario and control requirements. When selecting a gear reducer, factors such as the load condition, operating speed, and output torque of the press need to be considered. At the same time, the durability and reliability of the gear reducer are also important considerations. It is necessary to choose a gear reducer with high quality and reliability to ensure stable and reliable operation of the electric servo press.
In practical applications, multiple reducers are often combined to achieve higher reduction ratios and higher torque output. For example, planetary gear reducers and worm gear reducers can be combined in series to achieve higher reduction ratios and higher torque output. At the same time, gear reducers also need to be regularly maintained and serviced in practical applications to ensure their normal operation and prolong their service life.
In summary, the gear reducer of an electric servo press is one of the key components for achieving precise pressure and speed control. When selecting and using gear reducers, they need to be optimized according to actual application requirements and regularly maintained and serviced to ensure their stable and reliable operation.
Servo Transmission Device
The transmission device is a component that connects the reducer and the lower die, used to convert the low-speed, high-torque output of the reducer into the linear motion of the lower die. The transmission device is typically composed of components such as a screw rod, guide rail, coupling, and connecting rod. The screw rod is used to convert the rotary motion of the motor into the linear motion of the lower die, the guide rail supports the lower die and the workbench, the coupling connects the motor and the screw rod, and the connecting rod transmits the rotation of the screw rod to the lower die. The transmission device generally uses high-precision ball screw or gear transmission mechanism, which has the advantages of high precision, high rigidity, low friction, and long service life. The accuracy and rigidity of the transmission device directly affect the machining accuracy and stability of the machine.
The transmission device of the servo motor is a component that connects the motor shaft and the mechanical load. Its main function is to convert the rotary motion of the motor into the motion of the mechanical load and withstand the torque and inertia load of the mechanical load.
Commonly used transmission devices include gear transmission, synchronous belt transmission, and direct drive.
Gear transmission: Gear transmission is one of the commonly used servo motor transmission devices. It achieves different reduction ratios and torque outputs by combining different gears. The advantages of gear transmission are simple structure, high transmission efficiency, and high accuracy. However, the disadvantages are high noise, requiring regular maintenance and lubrication, and the high precision required between gear meshes.
Synchronous belt transmission: Synchronous belt transmission achieves transmission through the meshing of the belt teeth and gears. The advantages of synchronous belt transmission are smooth transmission, low noise, high precision, no need for lubrication and maintenance, etc. However, the range of torque output and reduction ratio is relatively small.

Principle
The principle of an electric servo press system
Controlling the motion speed and position of the machine
The main function of an electric servo system is to achieve high-precision control of the machine by controlling the motion of the electric motor and the screw transmission mechanism. The electric servo system of a servo electric press uses high-precision and high-response servo drivers and encoders to achieve high-precision control of the machine's motion.
For example, during the processing of a press, the electric servo system can control the speed and direction of the electric motor to drive the pressure plate to move downward through the screw transmission mechanism. The motion speed and position of the pressure plate can be monitored in real-time, and the control system can perform precise control according to the set parameters. When the set pressure or displacement is reached, the electric servo system can automatically stop, thus achieving high-precision control of the machine.
Providing high-precision position feedback signals
The electric servo system provides high-precision position feedback signals through position sensors such as encoders, which feedback the position information of the machine to the control system. The control system, in combination with the programming controller, achieves precise control of the machine's position. When the position deviation of the machine exceeds a certain range, the electric servo system can automatically adjust the machine's motion trajectory to ensure the machining accuracy of the machine.
For example, in the production of automotive components, electric servo presses can achieve high-precision control of the dimensions and shapes of complex parts through high-precision position control, thereby improving product yield and production efficiency.
Achieving High-Speed Response and Precision Control The electric servo system of a servo press can achieve high-speed response and precision control, meeting the requirements of high-precision machining. During mechanical motion, the control system can quickly respond to the mechanical motion requirements through real-time feedback information and control algorithms, thereby achieving high-precision control of mechanical motion.
For example, in the press machining process, the control system can achieve high-precision control of the dimensions and shapes of complex parts according to the different properties of the materials and processing requirements, adjust the machining speed and pressure of the machine to achieve the best machining effect. At the same time, the electric servo system can achieve smooth control of mechanical motion, avoiding severe vibration and noise during machine motion, thereby improving the stability and reliability of the machine and ultimately improving product yield and production efficiency.
Achieving Intelligent Control and Monitoring
The electric servo system of a servo press can be combined with a control system to achieve intelligent control and monitoring. By programming the machining program with a programmable controller and operating and monitoring through a human-machine interface, intelligent control and monitoring of the machine can be achieved, improving the production efficiency and reliability of the machine.
Achieving Multiple Motion Modes
The electric servo system can achieve multiple motion modes, such as conventional pressure processing, stretching processing, forming processing, etc., and can flexibly select the motion mode according to the processing requirements. At the same time, the control system can also automatically adjust according to different processing requirements, achieving control and monitoring of multiple motion modes of the machine.
Overall, the electric servo system of a servo press is a key component for achieving high-precision machining. With functions such as high-precision position control, high-speed response motion control, and intelligent control and monitoring, it can achieve high-precision control of the machine and flexible selection of multiple motion modes.
Control Principles of Electric Servo Presses
Closed-loop Control Principle
The control principle of electric servo presses is based on a closed-loop control system, which mainly consists of four parts: sensors, controllers, drive systems, and presses. Below is a more detailed explanation of each part.
Sensors: Sensors are used to measure the position and speed of the press. In electric servo presses, encoders are usually used as position sensors, and Hall sensors or photoelectric sensors are used as speed sensors. The encoder can convert the position information of the press into a digital signal and transmit it back to the controller. The speed sensor can measure the movement speed of the press, convert it into an analog or digital signal, and then transmit it back to the controller.
Controller: The controller is the core part of the control system of the electric servo press. The controller receives the position and speed information feedback from the sensors and compares it with the given target value to calculate the error signal. The error signal refers to the difference between the target value and the actual value. Then, the controller uses the PID algorithm or other control algorithms to generate control signals to control the speed and direction of the servo motor, so as to make the motion state of the press as close as possible to the set target.
Drive System: The drive system is a critical part that converts the control signal into the actual motion of the press. The drive system typically consists of amplifiers, servo motors, and encoders. The amplifier receives the control signal and amplifies it to an appropriate level before sending it to the servo motor. The servo motor converts electrical energy into mechanical energy and transmits motion to the press through the transmission system. The encoder measures the speed and position of the servo motor and feeds it back to the controller.
Press: The press is the controlled object. Eventually, the drive system controls the speed and direction of the servo motor to make the motion state of the press meet the given target. This control method can ensure that the motion state of the press is within the given target range and has high precision and stability.
In addition to the above four parts, the control principle of electric servo presses also includes other aspects:
System Model: The controller needs to know the characteristics of the controlled object, such as the dynamic response, inertia, and damping of the press. These characteristics can usually be obtained through system modeling. Modeling can use physical models or empirical models, such as models based on neural networks or fuzzy logic.
Control Strategy: In practical applications, appropriate control strategies need to be selected to meet different control requirements. For example, position control, velocity control, or force control strategies can be selected. Different control strategies require different control algorithms and parameter settings.
Human-Machine Interface: The human-machine interface is used to set and adjust the parameters of the control system and display real-time pressure and position information. The human-machine interface usually consists of a touchscreen, keyboard, and display, which can provide simple and easy-to-use operation and monitoring functions.
It can be seen that the control principle of an electric servo press is a complex system engineering, which requires consideration of multiple aspects, including sensors, controllers, drive systems, presses, pressure sensors, system models, control strategies, and human-machine interfaces. Through reasonable design and optimization, efficient, stable, and precise pressure control can be achieved.
PID Control Algorithm and Other Closed-Loop Control Algorithms
The closed-loop control algorithm of the servo press is one of the most critical parts of the press control system. The basic goal of these algorithms is to control the speed and position of the servo motor to be as close as possible to the set target. Below are some common closed-loop control algorithms.
PID Control Algorithm
The PID algorithm is one of the most commonly used closed-loop control algorithms for servo presses. The PID algorithm decomposes the error signal into three parts: proportional, integral, and derivative terms, hence the name PID control. The proportional term refers to the current value of the error signal, the integral term refers to the cumulative value of the error signal, and the derivative term refers to the rate of change of the error signal. Then, the PID algorithm weights and sums these three parts to generate a control signal. By adjusting the three coefficients (Kp, Ki, and Kd) in the PID algorithm, the response speed, stability, and robustness of the control system can be optimized.
Proportional Part: The proportional controller amplifies or reduces the error signal according to a certain proportional coefficient based on the size of the error signal to obtain the proportional output value. The size of the proportional coefficient determines the sensitivity of the proportional controller, which is the speed at which the controller responds to the error signal.
Integral Part: The integral controller integrates the error signal to obtain the integral output value. The integral controller can eliminate the static error of the system, improve the stability and accuracy of the system.
Derivative Part: The derivative controller differentiates the error signal to obtain the derivative output value. The derivative controller can eliminate the dynamic error of the system and improve the dynamic response speed of the system.
Specifically, the proportional term (P term) generates a control signal based on the current error signal size, and its coefficient Kp determines the response speed and stability of the control system. When Kp is large, the control system responds quickly but may also produce overshoot and oscillation; when Kp is small, the control system responds slowly but is more stable.
The integral term (I term) accumulates the error signal, allowing the control system to produce a larger response to long-term errors, and its coefficient Ki determines the stability and static error suppression ability of the control system. When Ki is large, the control system has a strong ability to suppress static errors but may also have stability issues; when Ki is small, the control system is more stable but has poor static error suppression ability.
The role of the differential term (D term) is to compensate for the rate of change of the error signal, enabling the control system to respond quickly to instantaneous changes in error. The coefficient Kd determines the control system's ability to resist interference and stability. When Kd is large, the control system has strong suppression ability against interference signals, but it is also susceptible to noise amplification. When Kd is small, the control system's ability to resist interference is poor, but it is more stable.
By adjusting the three parameters in the PID algorithm, the response speed, stability, and accuracy of the control system can be optimized, achieving more accurate and reliable control. However, in practical applications, the problems with the PID algorithm also need to be considered, such as system delay, saturation, and other issues that can affect the performance of the PID algorithm, requiring adjustment and optimization according to specific situations.
The three parts of the PID controller work together to control the controlled object by processing the error signal. The parameters of the PID controller need to be adjusted according to the characteristics of the controlled object to achieve the best control effect.
Fuzzy control algorithm is a control algorithm based on fuzzy logic principles. The fuzzy controller maps the input variables and output variables to a set of fuzzy sets and adjusts the output variables according to a set of fuzzy rules. The fuzzy controller is suitable for control systems with fuzziness and uncertainty. Its advantage is that it can be used for control without requiring a specific mathematical model. The disadvantage of the fuzzy controller is that it requires manual setting of fuzzy rules and fuzzy sets, which requires some experience and skills.
Neural Network Control Algorithm
The neural network control algorithm is a control algorithm based on the principles of neural networks. The neural network controller typically consists of a feedforward neural network and a feedback controller. The feedforward neural network is used to predict the output of the controlled object, while the feedback controller adjusts the control signal based on the error signal. The neural network controller has adaptability and learning capabilities, allowing it to adapt to changes in the controlled object. The downside of the neural network controller is that it requires a large amount of training data and computational resources, and has a high computational complexity.
Adaptive Control Algorithm
The adaptive control algorithm is a control algorithm based on the characteristics of the controlled object itself. The adaptive controller can adjust the control signal based on real-time measurements of the state of the controlled object, thus achieving more accurate control. Adaptive control algorithms include model reference adaptive control algorithms, adaptive sliding mode control algorithms, and adaptive fuzzy control algorithms. The advantage of adaptive control algorithms is that they can adapt to uncertain controlled objects and environmental changes, but they require some algorithm design and debugging.
Predictive Control Algorithm
