Forging forming process of automobile chassis ultrathin-walled tubing

Abstract

The invention discloses a process for forging and forming an ultra-thin-walled tube of an automobile chassis. The process includes the following three steps: Step 1. After degreasing and derusting the surface of the metal material body, the surface is added by chemical reaction. Metal film protective layer; step 2, by replacing the material of the upper punch and the lower punch in the mold with SKH59 high-speed steel, the material of the mold core is replaced with ST7 tungsten steel, and the surface of the punch is plated with chromium by electroplating Aluminum-titanium coating; Step 3: During the forging process, continuously add special lubricating oil to the forging space, the special lubricating oil is composed of ordinary lubricating oil, TM-01 lubricating oil additive and molybdenum disulfide. This process ensures the one-time forging and pressing of the multi-function machine tool, the production speed of the product is fast, the investment in equipment is small, the cost is saved, and the quality is improved.

Description

technical field [0001] The invention relates to the technical field of automobile parts production, in particular to a process for forging and forming ultra-thin-walled tubes of automobile chassis Background technique [0002] Existing technical solutions: At present, the production of ultra-thin-walled tubes for automobile chassis adopts multiple low-speed extrusion + mechanical cutting processing by hydraulic presses, and multiple hydraulic presses and processing equipment are required for the shape and size of the product. Due to the thin wall of the product, if one-time forming is adopted, the metal flows quickly, the accumulated heat cannot be cooled, and the product is easy to pull; the mold is easy to stick to material. [0003] The multi-position cold heading and forging processing is a continuous automatic processing method, which can replace multiple hydraulic machining, and the production efficiency is 3,000 pieces per hour. The processing method greatly reduces ...

Due to the thin wall of the product, if one-time forming is adopted, the metal flows quickly, the accumulated heat cannot be cooled, and the product is easy to pull; the mold is easy to stick

[0003] The multi-position cold heading and forging processing is a continuous automatic processing method, which can replace multiple hydraulic machining, and the production efficiency is 3,000 pieces per hour. The processing method greatly reduces the processing efficiency of the entire product, which greatly increases the production cost. In order to improve the processing efficiency of the product and have greater competitiveness in the same industry, it is necessary to shorten the processing process, improve production efficiency, and reduce production costs.
