Automobile A-pillar manufacturing method

Abstract

The invention relates to an automobile A-pillar manufacturing method, and belongs to the technical field of automobile body structure design. The automobile A-pillar comprises a framework, a U-shapedclamping groove is formed in the edge of the framework, a transparent glass material is installed in the middle of the framework, and the framework is connected with the transparent glass material through an annular clamping groove. The framework is divided into an automobile A-pillar inner part and an automobile A-pillar outer part, and the automobile A-pillar inner part and the automobile A-pillar outer part are welded into a whole through a plasma arc welding method. An aluminum alloy material is adopted, so that the weight can be reduced under the condition that the strength of the automobile A-pillar is met. The two parts of the automobile A-pillar can achieve the effect of one-side welding and two-side forming through the plasma arc welding technology, and compared with existing common electric resistance welding, the welding seam is attractive, and the welding effect is good. A polariscope is selected as the transparent glass material, the view blind area caused by the automobile A-pillar is effectively reduced, meanwhile, the sight is not disturbed in the linear driving process, and the driving safety is improved.

Description

technical field [0001] The invention relates to a method for manufacturing an automobile A-pillar, which belongs to the technical field of automobile body structure design. Background technique [0002] With the continuous development of the social economy, automobiles are an important means of transportation. In order to ensure people's travel safety, it is necessary to continuously improve the safety of automobiles. As an important part of the car, the car body has an important impact on the safety performance indicators of the car. As an important structure of the car, the support column should be specially paid attention to in the design. The A-pillar is a structure that directly affects the driver. According to the current technical level, most of them use high-strength alloy materials and increase the cross-sectional area to increase the strength of the supporting pillars. However, the cost of high-strength alloy materials, such as titanium alloys, is too high. , At t...

The A-pillar is a structure that directly affects the driver. According to the current technical level, most of them use high-strength alloy materials and increase the cross-sectional area to increase the strength of the supporting pillars. However, the cost of high-strength alloy materials, such as titanium alloys, is too high. , at the same time, the cross-sectional area of ​​the A-pillar becomes larger, which will expand the driver's blind spots on the left and right sides, which will have the opposite effect
