Production process of automobile body side impact beam

Abstract

The invention provides a production process of an automobile body side impact beam. The production course of the production process includes preparing steel plates, blanking the steel plates according to the shape of the automobile body side impact beam, and subjecting the blanked steel plates to deoiling and rust removing; heating the pre-treated steel plates, subjecting the pre-treated steel plates to compression molding by a hot stamping machine, and cooling the steel plates to room temperatures; and subjecting the steel plates which are subjected to stamping forming and cooling to punching and trimming processing to form the automobile body side impact beam. According to the production process of the automobile body side impact beam, the steel plates are heated and then subjected to hot stamping molding, so that the problems that the steel plates are prone to crack, low in strength, low in anti-impact level and excessive in resilience due to cold stamping are prevented; and the steel plates are heated and cooled in vacuum environments, so that the problem that the steel plates are oxidized by oxygen in the air at high temperatures is avoided.

Description

technical field [0001] The invention relates to the manufacturing technology of automobile parts, in particular to a production process of the anti-side impact beam of the vehicle body. Background technique [0002] Cars often work in extremely harsh environments, with heavy loads, high speeds, high vibrations, and high dust, and are often exposed to the sun and rain, and the working temperature varies greatly. more stringent requirements. Various sheet metal parts such as roof, car wall, car cover, roof side beams, suspension brackets, longitudinal load beams account for a large proportion of auto parts, and the manufacturing process of these sheet metal parts directly affects its The final strength, hardness, and thickness of the selected sheet, etc., will have an impact on the overall quality of the car and consumables. The sheet metal parts in the prior art auto parts generally adopt the cold stamping manufacturing process. The cold stamping manufacturing process is ea...

AI Technical Summary

Problems solved by technology

[0003] In order to meet the requirements of automobile lightweight, reduce fuel consumption, reduce pollutant emissions and improve automobile collision safety, the plates used in many sheet metal parts of automobiles, such as roof side beams and longitudinal load beams, not only require high strength, but also And the wall thickness is also relatively thick. If the cold stamping process is used, a large stamping force is required, and the sheet metal parts are prone to cracking, causing excessive springback and affecting the subsequent assembly of the car body; The level is lowered, which affects the safety of the car
