Aluminum foil expansive sticking device for upper shells of gas generators

Abstract

The invention discloses an aluminum foil expansive sticking device for upper shells of gas generators. The device comprises a base, wherein a frame-shaped main support is arranged above the base, a sliding feeding block is movably arranged on the upper surface of the base, one end of the sliding feeding block is connected with the output end of a gas cylinder through a connecting rod, and the gas cylinder is connected with a gas pump; the sliding feeding block is pulled back and forth through the action of the gas cylinder; a hydraulic oil cylinder is arranged above the main support, and an output cylinder rod of the hydraulic oil cylinder is vertically downward and fixedly connected with a press rod. The aluminum foil expansive sticking device is reasonable in structure, convenient to use and high in overall efficiency, can perform aluminum foil expansive sticking on the upper shells of multiple gas generators simultaneously, is provided with a safety mechanism and avoids the injury condition.

Description

technical field [0001] The invention relates to the field of expansion sticking devices, in particular to an aluminum foil expansion sticking device for an upper shell of a gas generator. Background technique [0002] In the gas generator used for automobile airbags, the vent holes arranged in the circumferential direction on the side wall of the gas generator upper shell play the role of exhaust pressure relief when the gas generator is detonated. It is necessary to paste a circle of aluminum foil on the inner side wall of the upper casing of the gas generator corresponding to the exhaust hole. Since the aluminum foil is not firmly attached to the inner wall of the upper shell of the gas generator during the operation, it is necessary to press the aluminum foil to tightly bond the aluminum foil to the inner wall of the upper shell of the gas generator. At present, the operator uses a pressing rod to press the aluminum foil to make it adhere to the inner wall of the upper s...

AI Technical Summary

Problems solved by technology

At present, the operator uses a pressing rod to press the aluminum foil to make it adhere to the inner wall of the upper shell of the gas generator. Due to the small diameter of the upper shell of the gas generator, the operation is inconvenient, the production efficiency is low, and the pressure of manual pressing is low and the force is not strong. Uniformity, resulting in the aluminum foil and the inner wall of the upper shell of the gas generator not tightly bonded, and the product quality is poor; Patent No. CN204867989U discloses an aluminum foil expansion device for the upper shell of the gas generator, but the device can only process one product at a time, and the efficiency is very low
