Problems solved by technology

[0002] In the production process of the left and right windshield sheet metal parts of the automobile, the existing technical process is unreasonable, the utilization rate of the equipment is low, the work efficiency is low, the connection between the upper and lower processes is not thorough enough, and there are many places and manpower such as erasing oil and welding slag. Operation and production rhythm are not coordinated with the realization of assembly line operation, which seriously affects the demand for modern large-scale production, and the low pass rate of products seriously affects product quality

Embodiment Construction

[0022] The present invention is designed for the processing technology of the sheet metal parts of the left and right windshields of automobiles, and has made significant improvements on the original basis, including the following processes:

[0023] Process 1, shearing machine blanking;

[0024] Process 2, cutting and punching of mold cut-to-length material;

[0025] Process 3, mold forming;

[0026] Process 4, mold bending;

[0027] Process 5, mold separation and punching;

[0028] Process 6, butt resistance welding;

[0029] Step 7, pickling, phosphating;

[0030] Process 8, electrostatic spraying;

[0031] Process 9, loading and storage.

[0032] 1) Adjustment and improvement of materials

[0033] (1): Add tolerance constraints (±0.25mm) to process 1. Shearing machine blanking size, within the allowable tolerance range of the product, the requirements can be met after testing.

[0034] (2): Due to the improvement of the dimensional accuracy of process 1. Shearing m...

Abstract

The invention relates to a technical process of manufacturing sheet metal components of automobile left and right wind guide covers. The technical process includes: step 1, blanking by using a plate shearing machine; step 2, shearing and punching fixed-length die materials; step3, shaping the die; step 4, folding the die; step 5, punching holes in the die in a separate manner; step 6, performing butt resistance welding; step 7, pickling and phosphatizing; step 8, performing electrostatic spraying; and step 9, loading and storing. The technical process in the invention increases the utilization rate of material and equipment, remarkably improves the working efficiency and increases the rate of qualified products. In the invention, raw material parameters, equipments in the workpiece process and manufacturing procedures and techniques are all designed. Therefore, good production effect is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a manufacturing process of sheet metal parts of left and right wind guide covers of automobiles. Background technique [0002] In the production process of the left and right windshield sheet metal parts of the automobile, the existing technical process is unreasonable, the utilization rate of the equipment is low, the work efficiency is low, the connection between the upper and lower processes is not thorough enough, and there are many places and manpower such as erasing oil and welding slag. The operation and production rhythm are not coordinated with the realization of assembly line operation, which seriously affects the demand for modern large-scale production, and the low pass rate of products seriously affects the product quality. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and proposes a manufac...
