Description

Technical Field

[0001] The utility model relates to the technical field of airbag brackets, in particular to a stamping die for a metal bracket of an automobile safety airbag. Background Art

[0002] An automotive airbag is a safety system, often referred to as an airbag. It primarily provides protection against head-on collisions. When the front of the vehicle is struck by a collision, a sensor activates the igniter in the inflator, igniting the sodium azide particles within the inflator. This releases a gas primarily composed of nitrogen. This gas then passes through a filter to remove ash and impurities before entering the airbag, inflating it. The airbag is typically housed in a storage box, which is mounted on the airbag bracket.

[0003] The installation position of the airbag on the car is different, and the shape of the airbag bracket is also different. However, when stamping airbag brackets of different shapes, the existing stamping machine needs to replace the mold. The staff needs to use external lifting equipment to lift the mold into the stamping machine and connect it to the stamping machine. The mold replacement is more troublesome, which affects the stamping efficiency of the airbag bracket. Utility Model Content

[0079] Working principle: First, the staff places the raw material on the lower mold 4. At this time, the staff starts the punching machine body 2. The telescopic end of the punching machine body 2 extends to drive the pressure plate 12 to move, so that the upper mold 9 cooperates with the lower mold 4 to punch the raw material. At the same time, the staff can place different molds from the outside on the carrying plate 3, and connect them with the second limit rod 7 to position and fix different molds. When the mold needs to be replaced, the staff controls the punching machine body 2 to drive the pressure plate 12 to move, so that the lower end face of the upper mold 9 fits with the upper end face of the lower mold 4, and at the same time rotates the bolt 11 to remove the bolt 11, and at the same time starts the punching machine body 2, so that its telescopic end drives the pressure plate 12 to move upward, so that the connecting groove 8 is separated from the connecting block 10, and at the same time, the staff starts the driving member 19. The rotation of the output end of the driving member 19 can drive the threaded rod 18 to rotate, and the rotation of the threaded rod 18 can drive the driving block 21 to slide in the sliding mouth 20. At the same time, the movement of the driving block 21 can drive the sliding block 14 to slide in the sliding groove 13. The sliding of the sliding block 14 can drive the supporting plate 3 to move, and the movement of the supporting plate 3 drives different molds to move to the bottom of the pressing plate 12. At the same time, the staff starts the punching machine body 2 to drive the pressing plate 12 to move, so that the connecting groove 8 is plugged into the connecting block 10 on the upper mold 9 in different molds. At the same time, the staff uses the bolt 11 to fix the connecting block 10 to the connecting groove 8, which is convenient for stamping the raw materials and brings convenience to people.
