Problems solved by technology

The gas generators for airbags have strict requirements on the production process during production and processing, and the process is cumbersome. At present, batch production is mostly carried out in the form of segmented processing, which not only affects work efficiency and increases man-hours, but also increases the need for gas generator products to be converted to different processing equipment. Defective products such as deformation and damage caused by disassembly and installation reduce the product qualification rate

Embodiment Construction

[0019] An automatic forming process for an airbag gas generator provided by an embodiment of the present invention includes the following steps:

[0020] S1: cut the material, cut the raw material, and pre-press to form the raw material for processing;

[0021] S2: Deep drawing, two-stage deep drawing is performed on the blank to form a two-layer stepped tube body;

[0022] S3: Pre-shaping, the surface of the stepped tube body is evenly applied to correct the shape by the up and down buckle of the shaping die;

[0023] S4: rough cutting, cutting off the remaining material on the outer edge of the bottom layer of the stepped tube body;

[0024] S5: punching, punching the top side wall of the stepped tube body;

[0025] S6: fine cutting, further finely trimming the outer edge of the bottom layer of the stepped tube body according to the preset size;

[0026] S7: Chamfering, using a mold with chamfering to fasten the stepped tube body, and chamfering the punching part;

Abstract

The invention relates to an automatic forming technology for an airbag gas generator. The technology comprises steps as follows: 1, cutting: raw materials are cut and pre-pressed, and a to-be-processed blank material is formed; 2, deep drawing: the blank material is subjected to two sections of deep drawing, and a two-layer stepping pipe body is formed; 3, pre-shaping: force is uniformly applied to the surface of the stepping pipe body through vertical buckling of a shaping die to correct the appearance; 4, rough cutting: excess materials on the outer edge of the bottom of the stepping pipe body is cut off; 5, punching: the top side wall of the stepping pipe body is punched; 6, accurate cutting: the outer edge of the bottom layer of the stepping pipe body is subjected to further accurate cutting according to defined size; 7, chamfering: the stepping pipe body is buckled by a die provided with chamfers, and the chamfers are punched; 8, shell nosing: the bottom of the stepping pipe bodyis bent inwards gradually, and final closed shell noising is performed; 9, setting: a finished product is subjected to final shaping processing by a shaping die. A highly integrated automatic processing device is obtained on the basis of the whole processing technology, so that the occupied area is reduced, the processing efficiency is improved, the processing time is shortened, and the success rate of product production is increased.

Description

technical field [0001] The invention relates to the field of airbag processing, in particular to an automatic forming process of an airbag gas generator. Background technique [0002] Airbags are equipped with gas generators of different specifications. When the vehicle collides, the gas generator inflates the airbag and deploys it to protect the safety of the passengers. The gas generator of the airbag has strict requirements on the production process and cumbersome procedures during production and processing. At present, it is mostly mass-produced by segmented processing, which not only affects the work efficiency and increases the working hours, but also increases the conversion of gas generator products to different processing equipment. Defective products, such as deformation and damage caused by disassembly and installation, reduce the qualified rate of products. SUMMARY OF THE INVENTION [0003] In order to achieve the above-mentioned purpose, the present inventio...
