Blanking and bending die provided with scrap discharge hole

Abstract

The invention discloses a blanking and bending die provided with a scrap discharge hole. The blanking and bending die comprises a stamping rod, an upper template, a lower template and guiding rods, wherein the stamping rod is fixedly connected onto the upper part of the upper template; the upper template is connected with the lower template through the guiding rods; each guiding rod is externally sleeved with a spring; a clipping punch, a material pressing plate and a bending punch are sequentially connected onto the lower side of the upper template from left to right; the upper part of the material pressing plate is connected with the upper template through a push rod; a reset spring sleeves the push rod; a concave die is fixedly connected onto the lower template; the scrap discharge hole is formed in the lower template; and the scrap discharge hole is on the left side of the concave die. The blanking and bending die is simple in structure and convenient for operation, and is safe and reliable; and two procedures of blanking and bending are finished in one step, so that the production efficiency is high, and the machining precision is high.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a punching and bending die with holes for discharging waste, which can simultaneously complete two processes of punching and bending parts. Background technique [0002] The bending process is a stamping process that bends the blank into a certain angle and a certain shape of the workpiece through a mold and a press according to the shape of the part. attached figure 1 The part shown is a typical L-shaped part. The shape and structure of the workpiece are relatively simple, and it is usually mass-produced. This part is generally processed through two processes of punching and bending. However, two sets of molds are required for the two processes. , complex processing and low production efficiency. Therefore, it is necessary to design a blanking and bending die with a waste discharge hole that can be formed at one time. Contents of the invention [0003] In view of the above-mentioned e...
