Abstract

The invention provides an edge distance punching die which comprises an upper die base, a lower die base, a male die and a female die. The edge distance punching die is characterized in that the male die is arranged on the lower die base, the female die is arranged on the upper die base, a striking rod is penetratingly arranged in the middles of the female die and the upper die base, a discharging plate is arranged at the top of the male die, and a discharging bolt is arranged between the discharging plate and the lower die base. The edge distance punching die is simple in structure, reasonable in arrangement and convenient to use; due to the flip-over type structure, the female die is not easy to damage, service life of the die is prolonged, punching of workpieces in which small holes are too close to edges can be completed efficiently, production efficiency is greatly improved, and production cost is saved.

Description

technical field [0001] The invention relates to a mold, in particular to a margin punching mold. Background technique [0002] In the production process, it is often necessary to punch the workpiece, and generally a punching die is sufficient. However, if the hole to be filled is very close to the edge of the workpiece, that is, the edge distance of the hole is very small, then the general punching die cannot meet the production demand. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a margin punching die. [0004] Technical solution: In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A margin punching die, comprising an upper die base, a lower die base, a punch, and a die, characterized in that: the punch is set on the lower die base, and the die is set on the upper die A punching rod is provided between the concave die and the upper die seat, a discharge...
