Polygonal detachable punch

Abstract

The invention provides a polygonal detachable punch which comprises a plurality of punch ejector rods arranged on a polygonal punch base, wherein fixed bolts corresponding to the punch ejector rods are arranged on the polygonal punch base. The polygonal detachable punch is convenient for replacement; and production efficiency can be improved, and production cost is reduced.

Description

technical field [0001] The present invention relates to polygonal detachable punches. Background technique [0002] In the process of manufacturing alloy products, a stamping device is required, and a punch is used in the stamping device. like figure 1 and figure 2 As shown, the existing punch includes the punch ejector rod 2 and the ejector rod seat 4 located at the bottom of the punch ejector rod 2. When it is installed on the polygonal punch base 1, the collar 5 needs to be set on the punch ejector rod 2 On the collar 5, a card slot 6 is set, and the fixing bolt 3 corresponding to the card slot 6 is set on the punch base 1, and the fixing bolt 3 is tightened to cooperate with the card slot 6 to clamp the collar 5. The ejector pin seat 4 is stuck between the collar 5 and the punch base 1, so that the punch is clamped. However, after the punch is damaged, the collar 5 needs to be taken out, and the punch ejector pin 2 and the ejector pin seat 4 are replaced together, w...

AI Technical Summary

Problems solved by technology

However, after the punch is damaged, the collar 5 needs to be taken out, and the punch ejector pin 2 and the ejector pin seat 4 are replaced together, which is inconvenient to operate and reduces the production efficiency, and the ejector pin seat 4 is replaced together, which also wastes materials. increased production costs
