Hole flanging structure applied to car safety airbag production

Abstract

The invention discloses a hole flanging structure applied to car safety airbag production, and relates to the technical field of punching molds of metal plate or pipe, bar or profile basic cutting-free machining or treatment. The structure comprises an upper die holder, an upper base plate, a fixed plate, a discharging cover plate, a discharging plate, a female die plate, a third lower base plate,a second lower base plate, a first lower base plate, a lower die holder, a first spring, a first nitrogen spring, a pressing block, an upper inserting knife, a product fixed insert, an upper slidingblock, a hole flanging female die, a lower sliding block, a lower inserting knife, a push block, a fixed block, a second nitrogen spring and a second spring. The upper inserting knife and the upper sliding block are of wedge structures, the lower inserting knife and the lower sliding block are of wedge structures, in the whole process, the upper inserting knife and the upper sliding block are in contact all the time, the upper inserting knife and the lower sliding block are in contact all the time, meanwhile, motions are stopped at the same time, the condition that the inserting knifes impactthe sliding blocks can be avoided, and the service life of the inserting knifes is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of perforation dies in basically non-cutting processing or processing of metal plates or tubes, rods or profiles, in particular to a perforation structure applied to the production of automobile airbags. Background technique [0002] With the advancement of science and technology and the improvement of living standards, cars have entered the lives of ordinary people. In order to improve the safety performance of driving and protect the safety of the drivers and passengers, safety airbags are generally installed on the car to protect the drivers and passengers when danger occurs during driving. At present, airbags are generally composed of airbag sensors, anti-collision airbags and electronic control devices. The anti-collision airbag device on the driver's side is installed in the steering wheel; the anti-collision airbag device on the passenger side is generally installed on the instrument panel. The airb...
