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 making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of upper punch as shown in Figs. 1-3, including upper punch body 1 and rectangular grafting block 9,
The upper surface of the upper punch body 1 offers ladder threaded hole 2, and the lower end surface of the upper punch body 1 offers square hole
7, offer the venthole 8 penetrated through with square hole 7 in the upper punch body 1, the upper punch body 1 by square hole 7 with
Rectangular 9 grafting of grafting block, the rectangular grafting block 9 are fixed on the upper surface of block plate 3, and the lower end surface of the block plate 3 is fixed with
Upper staking punch 5 is welded with wolfram steel pressing block 6, the upper staking punch 5 and upper punch master on the punching press end face of the upper staking punch 5
Fastening thread set 4 has been screwed on body 1.
Specifically, the side lower end of the upper punch body 1 is provided with external thread section, the fastening thread set 4 is outside
It is screwed in upper punch body 1,3 lattice of block plate is blocked in fastening thread set by the way that upper staking punch 5 is passed through fastening thread set 4
