Abstract

The invention discloses a hot-press and cold-press forming process for automobile safety air bags. The hot-press and cold-press forming process comprises the following steps that S1, the air bags with supporting rings are folded; S2, a robot conveys the air bags folded in the step S1 into a hot pressing device for pressurization and heating shaping; S3, the robot conveys the hot-pressed air bags into a cold pressing device for heat dissipation and cooling shaping; and S4, quality inspection is conducted on the air bags taken out in the step S3, products qualified in quality inspection are packaged, and one-time production is completed. According to the hot-press and cold-press forming process, the automobile safety air bags made of different materials are subjected to compression forming through the hot pressing and cold pressing combined technology, the size is made smaller after high-temperature hot pressing, the shaped air bags are not prone to rebounding or deforming, the cold pressing technology can rapidly lower the surface temperatures of the hot-pressed air bags, and it is guaranteed that the air bags cannot be cracked or deformed due to the temperature difference (160 DEG C or above) of the hot pressing and cold pressing technology. Therefore, the device can be quickly transferred to enter into the next assembling process.

Description

technical field [0001] The invention relates to the technical field of airbag production, in particular to a hot-pressing and cold-pressing forming process of an automobile airbag. Background technique [0002] The airbag system is a passive safety (see car safety performance) protection system, which is used in conjunction with the seat belt to provide effective anti-collision protection for the occupants. In car collisions, car airbags can reduce the head injury rate by 25% and the face injury rate by about 80%. [0003] After the production and processing of automobile airbags are completed, the airbags often need to be folded and then compressed and molded after the folding is completed. The reduction rate is not ideal, and the processing efficiency is low. Contents of the invention [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0005] A kind of automobile safety air ba...
