Embodiment Construction

[0021] The airbag gas generator continuous stamping forming process provided by an embodiment of the present invention includes the following steps:

[0022] S1: Cutting the raw material, cutting the raw material, and pre-pressing to form the raw material for processing;

[0023] S2: transfer, the transfer device transfers the blank from the cutting station to the first drawing station;

[0024] S3: The first stage of deep drawing, the first stage of deep drawing is carried out on the rough blank, and a columnar workpiece with a height of H is produced;

[0025] S4: transfer, the transfer device transfers the workpiece of the first drawing station to the second drawing station;

[0026] S5: Second-stage deep drawing, carry out second-stage deep-drawing on the workpiece, so that the punch of the second-stage deep-drawing station is set along the central axis of the columnar workpiece, and the height of the deep-drawing after the punch is ejected is greater than H, The punch d...

Abstract

The invention relates to a continuous punch forming technology for an airbag gas generator. The technology comprises steps as follows: raw materials are cut and pre-pressed, and a to-be-processed blank material is formed; the blank material is subjected to first-section deep drawing, and a columnar workpiece with height H is produced; the workpiece is subjected to second-section deep drawing, a punch of a second-section deep drawing position is arranged along a center axis of the columnar workpiece, the deep drawing height after the punch is ejected out is larger than H, and the diameter of the punch of the second-section deep drawing position is smaller than that of a punch of a first-section deep drawing position; N sections of deep drawing positions are set, the workpiece is subjected to stepping deep drawing, and the specific number of sections of the deep drawing and height are set according to processing parameters; cavities based on vertical buckled ejection press are adopted, and the workpiece after deep drawing is subjected to shaping press; the workpiece in a shaping position is conveyed to a cutting position by a conveying device; unnecessary waste is removed by cuttingedges and corners of the workpiece. The whole processing technology is highly integrated, so that 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 safety airbag processing, in particular to a continuous stamping forming process for a safety 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 passengers. The airbag gas generator is small in size, complex in shape, and has high quality requirements, so it is not easy to process. A continuous stamping and forming processing method is now designed for one-time stamping and forming to produce this product. Contents of the invention [0003] In order to achieve the above object, the present invention adopts the following technical scheme: the continuous stamping and forming process of the airbag gas generator comprises the following steps: [0004] S1: Cutting the raw material, cutting the raw material, and pre-pressing to form the raw mat...
