Blanking and bending die with limiting function and positioning function

Abstract

The invention discloses a blanking and bending die with a limiting function and a positioning function. The blanking and bending die with the limiting function and the positioning function comprises a punching rod, an upper die plate, a lower die plate and guiding rods. The punching rod is fixedly connected to the upper portion of the upper die plate. The upper die plate and the lower die plate are connected through the guiding rods. The guiding rods are further sleeved with springs. An edge cutting male die body, a pressing plate and a bending male die body are sequentially connected to the lower side of the upper die plate from left to right. The upper portion of the pressing plate is connected with the upper die plate through a push rod. The push rod is sleeved with a reset spring. A female die body is fixedly connected to the lower die plate. An upper limiting column is further arranged on the lower end face of the upper die plate. A lower limiting column is arranged in a corresponding position of the upper end face of the lower die plate. The limiting columns are used for limiting the downward movement extreme position of the upper die plate. A positioning block is further arranged on the lower die plate and located at the right side of the female die body and below the right portion of the bending male die body. The blanking and bending die with the limiting function and the positioning function is simple in structure, convenient to operate, safe and reliable; due to the fact that the blanking procedure and the bending procedure are completed at a time, 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 position limitation and positioning 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 punching and bending die with limit and positioning that can be formed at one time. Contents of the invention [0003] In view of the above-menti...
