Abstract

The invention discloses a composite molding process for an electric vehicle chassis suspension assembly. The composite molding process for the electric vehicle chassis suspension assembly is characterized by comprising the following steps of 1, drawing molding; 2, upper sealing sleeve rolling; 3, injection molding; 4, fixing base fixing; 5, lower sealing sleeve jacking; 6, fixing box jacking; 7, composite flanging and molding; 8, primary composite molding part plastic spraying; 9, primary composite molding part fixing; 10, shock-proof buffering ring jacking; 11, upper sealing sleeve jacking; 12, fixing ring jacking; and 13, fixing box rolling. After all parts are drawn and molded through a drawing mold, a fixing base serves as a main assembly part; all the parts are sequentially clamped into the fixing base through a hydraulic cylinder, and then flanging is conducted through the hydraulic cylinder, so that all the parts are tightly clamped; and compared with existing welding connecting, the drawing cost is low, assembly is reliable, the fastness is good, the overall strength is high, the service life is long, welded joints are avoided, the appearance is attractive, the machining period is short, and the production efficiency is high.

Description

technical field [0001] The invention relates to a composite molding process of an electric vehicle chassis suspension assembly. Background technique [0002] The vehicle will encounter different road conditions during driving, and the tires between the vehicles will be affected by the airflow and wind resistance on both sides, resulting in micro-movement and bumps, which will affect the comfort of the passengers. The chassis of existing vehicles all adopt the traditional "MacPherson" suspension structure. The components of the suspension of this structure are fixed by welding connections and fasteners. The iron plates at the welding connections are affected by stress, and the suspension is affected by impact and collision. After that, it is easy to deform, has poor strength and short service life. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a composite molding process for an electric...
