Support punching die

Abstract

The invention discloses a support punching die. The support punching die comprises an upper die plate, a lower die plate, a guide column device, a female die, a male die assembly and a positioning block. The upper die plate is connected with the lower die plate through the guide column device. The lower die plate is provided with the female die. The male die assembly is arranged below the upper die plate. The lower die plate and the female die are provided with a through groove allowing the male die assembly to pass. The male die assembly comprises a male die and a boss. The section of the male die is in an isosceles trapezoid shape. The sum of the included angles of the two nonparallel sides of the isosceles trapezoid is 90 degrees. The boss is arranged on the outer side face of the male die. The bottom surface of the boss is located below the bottom surface of the male die. The outer side face of the boss is flush with the outer side wall of the through groove. The female die is provided with the positioning block. The support punching die is matched with a punching machine and arranged on a fixed disc of the punching machine, and the head of the punching machine pushes the male die downwards to punch angle steel; accordingly, punching accuracy is guaranteed, punching quality is improved, and punching efficiency is high.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die for a bracket used in the process of making a bracket. Background technique [0002] Made as attached figure 1 When described bracket, comprise the following process steps of one punching, namely in the attached figure 2 On the angle steel 12 shown, two notches 13 in the shape of an isosceles trapezoid are punched. In order to make the punching process fast and accurate, it is necessary to use a punching die. The previous stamping dies are relatively simple, but the punching accuracy is not high, and the quality of the punching process directly affects the next step of the process, so it is imperative to design a punching die with accurate punching. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a bracket punching die with high punching precision and high punching efficiency. [0004] T...
