Abstract

The invention discloses a cold-forging plastic molding technology of a precisely-forged brake threaded pipe component. The cold-forging plastic molding technology comprises the following steps of material cutting, annealing, blank making, shot-blasting, phosphorus saponifying processing, cold-forging reverse extrusion, annealing, shot-blasting, phosphorus saponifying processing and cold-forging cavity molding. Milling processing is not required by the technology, cold reverse extrusion and molding procedures are instantly finished, the production efficiency is high, the processing cost is low, the raw material is saved, the metal streamline of the material is complete and is not cut off, milling marks are not left on the surface, the product quality is stable, the comprehensive mechanical performance is high, both the accuracy and the strength of the product are ensured, the operation quantity of machine processing is reduced, and the development trend of modern world manufacturing industry is met.

Description

technical field [0001] The invention belongs to the technical field of forging and pressing forming of metal parts, and relates to a production process of a brake threaded pipe. Background technique [0002] The automobile brake threaded pipe is a key part of the brake assembly. The brake threaded pipe bears hydraulic pressure and requires high manufacturing precision and overall strength. The brake threaded pipe is an externally threaded pipe with a complex inner cavity structure. Currently, it is generally used Choose the bar for direct turning, and then drill and mill the inner cavity and bottom. This method has low production efficiency, waste of raw materials, and high production costs. Especially because the metal flow line of the raw material is cut off, the comprehensive mechanical properties are reduced, and it cannot be adapted. Today's manufacturing trends. Contents of the invention [0003] The invention aims at the deficiency of the inner cavity structure of ...
