From the working principle and structure of screw punch machine, it can be seen that screw punch machine has the following characteristics.  

1, the main machine structure of screw punch machine is simpler than friction press, low failure rate and easy maintenance.  Compared with the friction press, there is no need to replace the wear parts of the friction belt. Compared with the hydraulic screw press and clutch screw press, there is no hydraulic drive unit, and the maintenance cost is significantly reduced.  

2, the striking energy can be set accurately, forming precision is high, the tolerance of parts is small, especially suitable for precision forging.  Because it can control the striking energy accurately, it can reduce the load of the mold and prolong the die life obviously compared with the friction press.

3,screw punch machine can be programmed forging.  The main machine of screw punch machine can run automatically according to the pre-set energy of each work step.  After striking, the slider can also pause at the bottom dead center, and the pause time can be preset to meet the requirements of some processes.  

4.Due to the frequency conversion drive or switched reluctance servo drive, the screw punch machine will not impact the power grid of the factory and affect the operation of other equipment when working.  When the slider is stationary, the motor does not work and the power consumption is low.  When the flywheel energy recovery device is adopted, the power consumption can be further reduced and efficiency can be improved.  

5,screw punch machine has no bottom dead center, no need to adjust the mold height, will not suddenly stop running.  Mold structure is simple, easy to change mold.  It is convenient to adjust the height of the stroke and accurate return position
