Description

Technical Field

[0001] This utility model relates to the technical field of forging press tools, and in particular to a lower ejector device for a forging press. Background Technology

[0002] In the early stages, forging was done manually. Early ejector devices were simple fixing devices that could only support products of simple shapes. Because they couldn't provide cushioning during forging and were difficult to remove after forging, manual forging was not only inefficient but also produced poor-quality products. With the development of industrial technology, some simple forging presses emerged. However, these presses had unstable ejector devices during forging, and the material removal after forging was slow and inefficient. The instability of the ejector device affected the quality of the forged product. Currently, the ejector device of a forging press suffers from unstable forging and low efficiency during ejection. Therefore, these technical problems need to be solved. Utility Model Content

The material is forged by the upper pressure module of the forging press. As the extrusion movable module 8 descends, it is forged and formed by the mold on it. After forming, the upper pressure module rises. As the first spring 10 and the second spring 12 regain their elasticity, the movable module 8 is lifted up. Then, the motor 6 is started to drive the cam 7 to rotate and lift the arc-shaped stop 15, thereby driving the top rod 14 to push upward and push the forged material out of the movable module 8. As the cam 7 continues to rotate, the arc-shaped stop 15 loses its extrusion, and the third spring 16 regains its elasticity and resets the top rod 14.
