Screw pressing machine is mainly used for the processing of high, medium and low grade refractory products, or the processing and forming of various metal materials products (cold and hot forging, casting forging) and other processes. The main classifications of screw pressing machines are as follows:
1. According to the type of transmission mechanism, screw pressing machine can be divided into friction type, electric type, hydraulic type and clutch type.
3. According to the number of screw is divided into: single screw, twin screw and multi screw type.
4.According to the process use,screw pressing machine can be divided into universal press, stamping press, forging press, etc.
5.According to the structure, it can be divided into anvil block type and non-anvil block type.
The screw pressing machine of Zhengzhou Hualong Machinery Manufacturing Co., LTD is driven and controlled by permanent magnet synchronous servo motor, which is composed of two parts: mechanical part: frame, flywheel, screw nut, slider, lubrication mechanism, braking mechanism and electrical part: servo motor, electrical control cabinet, operation button station and so on. It is the update product of friction press.
The working principle of the screw pressing machine is that it gives instructions to the motor through the servo control system, and then the motor starts to drive the flywheel to make the screw rotate, and then turns the rotating motion into the reciprocating motion up and down to complete the striking action. Strike force, speed, frequency and so on are controlled accurately by digital program.
