It is understood that a servo press usually refers to a press driven and controlled by a servo motor. Including servo presses for metal forging and special servo presses for refractory industry. Because of the numerical control characteristics of servo motor, it is sometimes widely called numerical control press. Servo press
First, the servo technology of servo press
The servo press adopts single or multiple servo motors, and the control system adopts computer control and digital and feedback control technology. Moreover, the modern servo press has strong technological adaptability, low noise and low energy consumption, which can greatly improve production efficiency.
After years of development, servo technology has been widely used in stamping field. In the field of in-process molding press and auto parts press, servo technology has gradually matured through the efforts of many practitioners and technicians, and has been recognized in many industries, and has begun to be accepted by more and more production enterprises.
Second, the applicable process of servo press
Servo presses are used in many industries, and the assembly of medium-sized parts in automobile and auto parts industries is realized by pressure assembly.
As a new technology, servo press has advantages that traditional hydraulic press does not have. The advantages of selecting servo press for automobile parts are mainly reflected in the following aspects.
1, die life is long, pressure is numerically controlled, and the die will not be damaged due to overload.
2. The equipment structure is extremely simple and the cost is low.
3, intelligent automatic numerical control, the operation of the press is intelligently controlled by a high-speed computer, which can realize full automation without manual operation.
4. The equipment has high reliability, no wearing parts, higher strength than permanent magnet servo motor, firmness, reliability and impact resistance. Maintenance-free equipment effectively saves maintenance personnel and working hours.
Third, the production embodiment of servo press
Servo press represents the development direction of press, and it is of great economic and social significance to study servo press directly driven by servo motor.
1, productivity improvement.
2. The product has high precision. Through closed-loop feedback control, the accuracy of the bottom dead center is always guaranteed, the burr of the product is suppressed, and the generation of defective products is prevented.
3. Low noise and long service life of the die. Compared with the general mechanical press, the noise is greatly reduced, and the vibration of the die is small and the service life is long.
4. Energy conservation and environmental protection. It cancels the energy-consuming parts of the traditional mechanical press, simplifies the mechanical transmission structure and consumes less electricity, so the operating cost is greatly reduced.
Fourth, the future trend of servo press
The application of servo press technology opens a door for the precise and intelligent control of modern machinery. The application of servo press in press-fitting technology shows obvious advantages in product forming, automation realization, die life, energy utilization and failure rate. With the rapid growth of new energy vehicles and other industries in China, the market demands more stringent manufacturing equipment. Obviously, servo press has become the mainstream equipment of precision and intelligent press-fitting production line, and it has occupied all walks of life to a great extent.
