Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
As Figure 1-Figure 5, the utility model relates to a kind of gas generator flange link crimping device, including upper mold
And lower die, the upper mold include one piece of rectangle gusset piece 2, are connected below gusset piece 2 by four connecting shafts 1 being arranged symmetrically
There is flange 4, is arranged with plastic springs 9, the plasticity between gusset piece 2 and flange 4 in every connecting shaft 1
Spring 9 is polyurethane elastomer.1 lower end of connecting shaft is connect by axially disposed bolt with flange 4, connecting shaft
1 upper end passes through gusset piece 2 and is limited by outer circlip 14.It is pressed in bolt connection of the gusset piece 2 below by circumference uniform distribution
First 3, seaming chuck 3 is that ladder shaft-like and lower part and 4 inner hole upper gap of flange cooperate, for depressing rear insertion flange
Generator main body 11 is pressed into flange 12 in 4.
The lower die includes pedestal 5, and floating spring 8 and floating seat 6 have been sequentially inserted into the centre bore of pedestal 5, is floated
Spring 8 is clamped in pedestal 5 between the centre bore of 6 bottom of bottom and floating seat.The floating seat 6 be it is cylindrical and with pedestal 5
The cooperation of centre bore upper gap, be symmetrically threaded with spacer pin 10 in 6 outer rim two sides of floating seat, spacer pin 10 respectively by
The long hole 501 being symmetrically arranged on 5 side wall of pedestal is pierced by, the axial limiting for floating seat 6.In in the centre bore of floating seat 6
