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. The cutting size of the shearing machine, within the allowable tolerance range of the product, can meet the requirements after testing.

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

Abstract

The invention relates to a novel manufacturing technology of sheet metal parts. The technological process relates to the manufacturing procedures and process of sheet metal parts of left and right wind scoopers of automobiles. The novel manufacturing technology comprises the manufacturing procedures of procedure 1, blanking of a plate shearing machine; procedure 2, fixed length cutting and punching of a mold; procedure 3, mold forming; procedure 4, mold bending; procedure 5, separation punching of the mold; procedure 6, butt resistance welding; procedure 7, acid pickling and phosphorization; procedure 8, electrostatic spraying; and procedure 9, loading and storage. According to the novel manufacturing technology, the material and equipment utilization rate is increased, the working efficiency is greatly improved, the qualification rate of a product is greatly increased, parameters of the raw materials are designed, the equipment during the processing process is designed, the processing procedures and technology are designed, and a good effect is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a novel manufacturing process of sheet metal parts. 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 new type of sheet metal manufacturing process, which...
