Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figure 1, the technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of nutplate
High-precision punching die, including lower template 1, upper die holder 9 and lower die holder 16, the upper end of the lower template 1 is by feet 2 under
Die holder 16 is connected, and the top of the lower die holder 16 is provided with upper die holder 9, which is characterized in that the upper end of the lower die holder 16
Cushion block 4 is installed, the upper end of the cushion block 4 is equipped with bottom plate 14, is set gradually from left to right on the bottom plate 14
There are pre-punched hole fixing sleeve 5, deburring fixing sleeve 6, the floating bushing of falling interior angle 11 and fine blanking hole fixing sleeve 12, the upper die holder 9
Lower end is equipped with upper mounted plate 20, and the lower end of the upper mounted plate 20 is fixed with several formed punches 10, the upper mounted plate
20 lower section is provided with the pressure plate 7 being connected with the top nitrogen gas spring 8 in upper die holder 9, the top of the bottom plate 14
It is provided with the stripper plate 13 being connected with the floating bushing of falling interior angle 11, the upside of the lower template 1 is equipped with lower part nitrogen gas spring 18,
The upper end of the lower part nitrogen gas spring 18 is connected with top plate 19, and the upside of the top plate 19 is vertically-mounted to have upper end floating with interior angle
The float mandrels 17 that the lower end of dynamic set 11 is mutually pushed up.
As an embodiment of the present invention, when molding, upper die holder 9 is pushed, and pressure plate 7 is driven to remove
Pressure, following material plate is pressed on stripper plate 13, and stripper plate 13 is pressed down, and formed punch 10 downwards carries out material plate
Punching, with the movement of material plate, successively to the same hole carry out pre-punched hole, tooth burr, fall interior angle and fine blanking hole process,
When die sinking, float mandrels 17 can up push up under the action of lower part nitrogen gas spring 18, by the floating bushing of falling interior angle 11 and de- material
