Abstract

The double-end stamping tool comprises a double-end stamping tool body, wherein oblique sides at two ends of the double-end stamping tool body in the longitudinal direction are respectively formed into an oblique tool face I and an oblique tool face II, and grooves I and grooves II for jogging and fixing are formed on the surfaces of the two lateral sides respectively adjacent to the corresponding oblique tool faces I and II. The punching tool assembly comprises a double-end punching tool and a power block, wherein the power block is provided with an embedded groove which is opened towards one side, the bottom surface of the embedded groove comprises an inner inclined surface I and an inner inclined surface II which are not coplanar in a longitudinal section view, so that when the double-end punching tool is inserted into the embedded groove along the groove wall on one side adjacent to the inner inclined surface I, the inclined knife surface I or the inclined knife surface II is attached to the inner inclined surface I, and meanwhile, the corresponding knife tip part stretches into and is suspended at the bottom of the groove taking the inner inclined surface II as the bottom surface of the groove beyond the inner inclined surface I. So that the service life can be prolonged and the cost can be saved.

Description

Double-end punching tool and punching tool assembly Technical Field The utility model relates to the field of punching tools, in particular to a double-head punching tool and a punching tool assembly corresponding to the double-head punching tool. Background After extrusion, aging and sand blasting, the aluminum alloy photovoltaic frame profile needs to be subjected to various deep processing including a stamping procedure, wherein the stamping tool is a wear consumption part, and the cost of the wear part is high. For this reason, there remains a need for an improved design that can extend service life and save costs. Disclosure of utility model In order to solve the above problems, an objective of the present utility model is to provide a dual-head punch and a punch assembly corresponding to the dual-head punch. According to an aspect of the present utility model, there is provided a double-ended punch having a longitudinal section with a parallelogram outer contour and a polygonal cross section, wherein oblique sides at both ends in a longitudinal direction are respectively formed into an oblique cutting surface I and an oblique cutting surface II, and grooves I and grooves II for fitting and fixing are respectively formed on surfaces of both lateral sides adjacent to the corresponding oblique cutting surface I and oblique cutting surface II. Preferably, the double-end punching tool is formed to have a rectangular cross section, and the longitudinal section is of a central symmetry structure.
