Problems solved by technology

The keyway processing of machined parts is processed by milling or broaching. For automobile shock-absorbing pipe fittings with both grooves and teeth, the current conventional processing method is to first cold-head the product and then perform milling. The processing procedure is twice, which takes a long time and affects production efficiency

Abstract

The invention provides a machining method for a slotted slit toothed tube for automobile damping. According to the method, machining is performed through a cold header. The method comprises the following steps that S1, a cropping mold is used for cutting off wire rods into the needed length, and a product with a first end face and a second end face is obtained; S2, a deep hole is pressed at the first end face, and a shallow hole is pressed at the second end face; S3, the deep hole is punched to form a through hole; S4, teeth are pressed at the two end faces; S5, key grooves are pressed at thefirst end face and the second end face. The straight tube with the teeth at the two end faces and the key grooves in the two ends of an inner hole is obtained through cold heading one-time forming, machining procedures are simplified, the product efficiency is improved, the manufacturing cost is lowered, and the market competitiveness of enterprises is improved.

Description

technical field [0001] The invention relates to a processing and manufacturing process for automobile shock absorbing parts, in particular to a processing method for a slotted toothed pipe for automobile shock absorbing. Background technique [0002] At present, among the shock-absorbing straight pipe products used in automobiles, the products with teeth on the end face are more and more widely used, while those with teeth on the end face and key grooves at both ends of the inner hole are very few. The keyway processing of machined parts is processed by milling or broaching. For automobile shock-absorbing pipe fittings with both grooves and teeth, the current conventional processing method is to first cold-head the product and then perform milling. The processing procedure is two times, which takes a long time and affects production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and pro...
