Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0037] The gas generator molding device of the present invention includes a pyrotechnic body molding device and a finished product molding device, and the two devices are used as a set. The structure of the gas generator formed by this device includes an electric ignition tube 1, a base 2, and a shell 5, respectively as Figure 1a , 1b , 1c shown.

[0038] The firing body molding device is used to assemble the electric ignition tube 1 and the base 2 to form a firing body, including an upper mold 7 and a positioning seat 16. The structure of positioning seat I 6 is as follows figure 2 As shown, its upper surface is provided with a square protrusion 61, which matches the shape of the groove on the base 2, and the base 2 can be fixed on the positioning seat 16 to play the ...

Abstract

The invention discloses a gas generator forming device. The gas generator forming device comprises an ignition body forming device and a finished product forming device which are used for closing of a die and a positioning base. The positioning base is used for fixing a base or a semi-finished product. The die is of a cylindrical structure provided with a hollow structure and provided with an opening in one end, the die can vertically move relative to the positioning base, and an annular concave face is arranged at the position of the opening of the die and used for extrusion closing of the base or a product. The invention further discloses a gas generator forming method. An electric ignition pipe or an ignition body is fixed to the base, a press is started, the die vertically moves relative to the positioning base, the base or the product is extruded through the annular concave face of the die, pressure maintaining is conducted for a certain time, and the assembled product is taken out. The gas generator forming device is high in automation degree and simple in structure, forming of a gas generator can be efficiently conducted with the high quality, and the burden of manpower is relieved. According to the device, automatic product taking out is achieved by further utilizing elasticity of elastic components.

Description

technical field [0001] The invention belongs to the technical field of gas generators, and in particular relates to a molding device for a gas generator and a molding method for the molding device. Background technique [0002] The seat belt is called the "life belt" of the car. It plays an important role in protecting the personal safety of drivers and passengers. Collision damage, reducing the degree of damage to the occupant in the accident. The pre-tensioned seat belt is one of the most widely used seat belts at present. The characteristic of the pre-tensioned seat belt is that it will first tighten the seat belt when the occupant has not moved forward at the moment of a collision accident, and immediately put The occupant is tightly "tied" to the seat, and then locks the seat belt to prevent the occupant from leaning forward, effectively protecting the safety of the occupant. [0003] The gas generator (referred to as MGG) is mainly used in pre-tensioned seat belts. W...
