Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiments.

[0030] Such as figure 1 As mentioned above, a production process of an airbag medication cup includes the following steps: (a) trimming 1: cutting the sheet-shaped raw material to form a prefabricated shape, figure 1 The black part in is the part that needs to be cut. After the edge trimming is completed, the small area connection between each prefabricated shape is easy to cut. After the edge trimming is completed, perform the empty step 2 operation to reduce the product temperature; (b) Stretching 3: through stamping The equipment stamps the prefabricated shape to form a cavity that can hold explosives. The stretching process is completed in 3 steps. The height of each stretching process does not exceed 2mm, and after each step of stretching process, a space is set to cool the product; ( c) Reshaping 4: The cavity is reshaped 4 through the mold to ensure the bottom dimen...

Abstract

The invention discloses a production process of an explosive cup for an air bag. The production process of the explosive cup for the air bag comprises the following steps: edge trimming: shearing a sheet raw material to form a material in a preset shape; stretching: stamping the material in the preset shape through stamping equipment to form a cavity capable of containing explosives; shaping: shaping the cavity through a mold to guarantee the boundary dimension of the bottom of the explosive cup; side piercing: piercing a side surface of the explosive cup, and strictly controlling the size of a hole site; and extrusion: finally determining the boundary dimension of the explosive cup by extrusion. The materials in the preset shape are arranged continuously, the five working procedures are successively set on the stamping equipment, and work simultaneously, by conveying equipment, raw materials are successively conveyed to various stations, therefore, the production efficiency is improved effectively, the quality of products is controlled effectively, and the practical value is high.

Description

technical field [0001] The invention relates to a production process of a safety airbag medication cup, which belongs to the field of auto parts processing. Background technique [0002] The car airbag system is a passive safety protection system. It is used in conjunction with the seat belt to provide effective anti-collision protection for the occupants. When a car collides, the car airbag can reduce the head injury rate by 25% %, the facial injury rate is reduced by about 80%, so it is widely used in the automotive field. [0003] Existing air bag assembly mainly is made up of safety air bag, gas generator and igniter etc. Among them, the gas generator ignites the gas generating agent after receiving the signal, and produces a large amount of gas, which enters the airbag after being filtered and cooled, so that the airbag breaks through the liner and expands rapidly in a very short time, and the medicine cup is used to hold the igniting gas The explosives used are very ...
