Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to shown in Fig. 1-3, a kind of compound punch of fine blanking hole suitable for medium plate, including it is fixed plate 1, compound
Drift 2, cavity plate 3, holding pad 4, guide plate 5 and polyurethane spring 6, the bottom of fixed plate 1 are provided with polyurethane spring 6, described
The centre of polyurethane spring 6 is provided with compound punch 2；The bottom side of compound punch 2 is provided with holding pad 4, the holding pad 4
Side is provided with guide plate 5；The bottom of guide plate 5 is provided with cavity plate 3, and the top of compound punch 2 is fixing end 23, described solid
The bottom of fixed end 23 is provided with the screw rod 231 with first through hole 232；The bottom of fixing end 23 is provided with connector 24, the connection
Part 24 includes swivel nut 242；The swivel nut 242 runs through the second through hole 241, and the inside of the second through hole 241 is provided with pin 243, institute
First through hole 232 is stated provided with parallel two, the first through hole 232 when the screw rod 231 is screw-inserted into 242 inside of swivel nut
