Vehicle punching mold convenient to demold

Abstract

The invention relates to the technical field of punching equipment, in particular to a vehicle punching mold convenient to demold. The vehicle punching mold comprises a punching base plate, a punchinggroove, a hydraulic driving mechanism, a convex mold, a fixed base, a slide column, a nut, an ejector block and an elastic piece. The vehicle punching mold convenient to demold has the following beneficial effects: after punching, through ejection of the ejector block by the elastic piece, punched parts sleeving the convex mold are ejected out of the convex mold by the ejector block, so that theautomatic demolding of the punched parts is realized; meanwhile, under ejection by the elastic piece, the ejector block can be leant against the edges of punched positions of the punched parts, so that the warpup and deformation phenomenon of the edges of the punched positions of the punched parts is reduced to at least a certain extent; and a high-frequency induction heating coil is provided andelectrified to quickly generate high temperature, so that the edges of the punched positions of the punched parts are quickly heated, the resistance suffered by the convex mold in the punching processis reduced, the punching efficiency is conveniently improved, and the damage to punching equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of stamping equipment, in particular to an automobile stamping die which is easy to demould. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among the steel products in the world, 60-70% are plates, most of which are stamped into finished products. The body, chassis, fuel tank, radiator fins of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped. There are also a large number of stamping ...

AI Technical Summary

Problems solved by technology

[0005] During the stamping process of auto parts, after the punch is processed, the stamped parts may be placed on the punch and cannot be demolded by themselves. At this time, manual demoulding is required, but manual demoulding will inevitably cause large damage. Security risk, but also less efficient
