Oil cooler accessory drawing die structure and production process thereof

Abstract

The invention relates to the technical field of stretching dies, and discloses an oil cooler accessory stretching die structure which comprises a punching machine, a mounting block is fixedly connected to the bottom of the punching machine, a mounting groove is formed in the bottom of the mounting block, a clamping block is inserted into the mounting groove, and screws are in threaded connection with the interior of the mounting groove and the interior of the clamping block. A die body is fixedly connected to the bottom of the clamping block, and mounting mechanisms are arranged at the top of the die body and the bottom of the punching machine. According to the oil cooler accessory drawing die structure and the production process thereof, through the arrangement of the mounting mechanism, when the die body needs to be mounted, only an extrusion ball needs to extrude a limiting block, so that the limiting block is clamped into a bayonet, and then a clamping block is limited through a screw, so that the die body can be mounted; and when an operator replaces different mold bodies, no excessive time is consumed, and then the production efficiency is improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a drawing die structure for an oil cooler accessory and a production process thereof. Background technique [0002] The mold used for stretching is called a stretching die, and the stretching die is a special tool for mass-processing materials (metal or non-metal) into required stampings. If there are many types of drawing dies to be distinguished according to the combination, they can be divided into single-process drawing dies, compound dies and progressive drawing dies, which are distinguished by stamping equipment, and can also be divided into single-action press drawing dies, double-action drawing dies Drawing dies for presses and drawing dies for three-action presses. The main condition for distinguishing them is the difference in blank holders (elastic and rigid blank holders). Drawing dies can also be divided into first drawing dies and The main difference between t...

AI Technical Summary

Problems solved by technology

[0003] At present, the production of automotive oil cooler parts needs to involve the requirements of stretching holes. The common method is stamping, but this stretching method may make the stretched parts insufficient in strength, and the surface of the stretched parts is smooth. The degree can not reach a certain quality, and then the finished product after the stretching of the parts cannot be used, causing certain economic damage, and the mold needs to be used when stretching the parts of the automotive oil cooler. In the prior art, the The installation of the mold is inconvenient. When different auto parts need to be stretched, different molds need to be replaced. Therefore, it is often necessary to disassemble and replace the mold, which will waste a lot of time and affect the efficiency of parts stretching production.
