Abstract

The invention discloses a special-shaped ejector pin small hole waste discharge system which comprises an extraction knife body and an ejector pin mechanism, wherein the size of a special-shaped ejector pin head is smaller than the diameter of an actual small hole by 5%, and after the special-shaped ejector pin head presses waste downwards, due to the fact that excavation grooves are formed in thetwo sides of the special-shaped ejector pin head, collision and scratching of edge materials of a product hole after rotating out are avoided; after a connecting sleeve is mounted at one end of a cylindrical protruding part, a rubber layer conducts buffering sealing on the connecting position of one end of the connecting sleeve and one end of the cylindrical protruding part; the rubber layer haslarge friction performance, so that the connecting position of the connecting sleeve and the cylindrical protruding part is attached more tightly; an SKD11 die steel layer is arranged on the surface of the special-shaped ejector pin head and the surface of the excavation grooves; the SKD11 die steel layer has good hardness and high toughness and is not prone to cracking; the abrasion resistance and corrosion resistance of the special-shaped ejector pin head can be enhanced through a smeared abrasion-resistant particle glue layer and a pvd nanometer abrasion-resistant coating, so that the special-shaped ejector pin head can be used for a long time, and the overall service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of thimbles, in particular to a small-hole waste discharge system for special-shaped thimbles. Background technique [0002] In the process of product processing, excessive discharge of waste materials will cause blockage of the thimble hole. After the thimble hole is blocked, it needs to be cleaned in time. If it is not cleaned in time, the jig will be damaged. [0003] However, the existing products use a cylindrical extraction knife to discharge waste from small holes. When the extraction knife is pressed down, it is easy to scratch and collide the edge material of the product hole, and many thimbles are welded and fixed. It is troublesome to disassemble and replace, and the thimble After a long time of use, it is prone to wear and tear, which makes the overall practicability, convenience and service life unsatisfactory. [0004] In view of the problems raised above, in order to improve the overall pract...
