Forging is the plastic deformation of metal produced by pressure, pressure equipment usually have forging hammer,screw  electric press machine and so on.  Spiral press is a kind of widely used forging equipment, it can complete a variety of different forging process, can be used for metal plastic forming, also widely used in building materials, refractory materials and other industries.  

Let's first analyze the performance characteristics of the screw electric press machine.  

1. the striking force is controllable: the screw electric press machine belongs to the energy limited equipment, and the weight of the striking force can be controlled by controlling the striking energy each time.  

2.moderate strike speed: the strike speed of screw electric press machine is between mechanical press and forging hammer, the maximum speed is 0.45~1.0m/s.  Because the speed is lower than that of forging hammer, it is beneficial to metal recrystallization recovery, and it is more suitable for forging low plastic alloy steel and non-ferrous metals and other aviation materials. 

3. the work stroke is not fixed: because the stroke is not fixed, it can automatically eliminate the impact of the elastic deformation of the body on the accuracy of the workpiece.  Multiple strikes can be achieved to obtain the desired deformation. 

4. large overload capacity: the strength of the screw electric press machine is designed according to the ultimate cold impact force, and the ultimate cold impact force of the screw press is about 3 times the nominal force.  

5. the impact vibration is smaller: because the striking force is closed by the fuselage, the basic investment is less than the forging hammer.  But the spiral pressure fuselage has unbalanced torque, so corresponding measures should be taken in the foundation design.  In addition, the noise is small, easy to meet the requirements of environmental protection, good working conditions.  

The performance characteristics of the screw electric press machine summarized above determine its importance to the forging industry.  Because of this, forging enterprises tend to choose screw electric press machine.
