Description

Technical field:

[0001] The invention relates to the technical field of forging machine tools, in particular to a mechanical lower forging extrusion and ejecting device of a forging machine press. Background technique:

[0002] The lower jacking device is one of the main components of the mechanical press. At present, most of the lower ejecting devices of forging presses on the market are cam type, and there are also a few pneumatic types. The above two lower ejector devices are mainly used for forging of forging machinery presses and ejection of forged parts. They have the characteristics of high-quality ejection, easy clamping of parts and automatic production. The above characteristics become the main functional requirements of forging machinery presses.

[0003] But now, with the rapid development of the manufacturing industry and fierce market competition, manufacturing companies have put forward higher requirements for the purchased equipment-meeting complex processes...
