technical field

The invention relates to the field of warm forging stamping, in particular to a lower ejector device for a warm forging press.

Background technique

Warm forging is one of the processing methods of metal plastic forming. In the existing lower ejector device for workpiece ejection of forging equipment, the power source is mainly pneumatic and hydraulic. When pneumatic is used as the power source, it has little environmental pollution, but the corresponding auxiliary equipment is complex, large in size and small in power; when hydraulic is used as the power source, it can provide large power, but it has high requirements on the environment and a long action cycle. Considering the environmental and space requirements of the warm forging process, as well as the characteristics of forgings, it is required that the press itself should have the characteristics of fast approach, low-speed work, and fast return. Therefore, the traditional pneumatic and hydraulic feeding devices can no longer meet the above requirements for warm forging processing. Based on the above problems, what kind of jacking device should be used to adapt to the characteristics of fast approach, low-speed work, and fast return of the press, so it is very necessary to design a new type of bottom jacking device for warm forging punches.
