About Servo Press Small Class

2025,05,16

A servo press usually refers to a press that uses a servo motor for drive control. It includes servo presses for metal forging and servo presses for industries such as refractory materials. Due to the CNC characteristics of servo motors, it is sometimes widely referred to as a CNC press.

Servo presses are divided into servo crank presses, servo connecting rod presses, servo screw press and servo hydraulic presses.

Servo crank press

In general, the eccentric teeth drive the slider crank to move up and down, and the curve is a sine curve. Generally, the maximum nominal tonnage is reached before the slider runs to the bottom dead point. The stroke is fixed and cannot be adjusted. General hydraulic presses can achieve engineering tonnage at any position of the slider stroke because they transmit pressure through liquid. The stroke is adjustable but the efficiency is low.

The servo press controls the movement of the slider through the motor, and combines the advantages of mechanical presses and hydraulic presses through pre-programming. It can achieve any type of stamping production at any stage of the stroke, and the pressure curve can be arbitrarily programmed.

Servo screw press

The traditional double-disc friction drive screw press has a friction disk that rotates continuously after the machine is started, which consumes a lot of energy, and the impact force is greatly affected by human factors, resulting in unstable product quality.

As an upgraded equipment for friction presses, in the fields of hot forging and refractory material forming processing, two types of electric screw presses, switched reluctance screw presses and servo screw presses, have appeared on the market according to the different drive motors.

The servo hydraulic press uses a servo motor to drive the main transmission oil pump, reduce the control valve circuit, and control the hydraulic press slide. It is suitable for stamping, die forging, press fitting, straightening and other processes. Compared with ordinary hydraulic presses, servo-driven hydraulic presses have the advantages of energy saving, low noise, high efficiency, good flexibility, and high efficiency, and can replace most existing ordinary hydraulic presses.
