Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

The puncher for spacer strip pressing mold of the present embodiment comprises: patrix and the counterdie opposite with described patrix.Patrix as shown in Figures 1 to 3, comprising: die shank 11, drift 12, drift holder 13, upper spring 14 and die 15.Die shank 11 connects drift holder 13, and drift holder 13 connects upper spring 14, and upper spring 14 connects die 15.Drift 12 is fixed on drift holder 13, and drift 12 runs through drift holder 13, upper spring 14 and die 15, the dead in line that die shank 1, drift 12, drift holder 13, upper spring 14 and die 15 are respective.The one side that die 15 deviates from spring 14 is formed with groove 151.

Counterdie as shown in Figure 4, comprising: fixed head 22 and the lower spring 21 be positioned on fixed head 22, and lower spring 21 and die 15 are oppositely arranged.

Because pad is generally circular, therefore the cross section of above-mentioned all parts is circle, and groove 151 is also circular.The spacer stamping device of the present embodiment is by being arranged on stamping machine by the die shank of patrix, and coordinate punching press with counterdie, stamping machine applies pressure to die shank 11, pressure is passed to sheet material by die shank 11, drift holder 13, upper spring 14 and die 15 successively, sheet material is pressed into circle by the groove 151 of die 15, and the circular hole in the middle of pad gone out downwards by drift 12, improves production efficiency relative to artificial pruning, reduce cost, and produced pad do not have defect or error dimensionally substantially.

As shown in Figure 1, die shank 11, drift holder 13, upper spring 14 and die 15 are fixed together (in Fig. 2 shown in dotted line) by the first screw 16.Two the first screws 16 have been shown in Fig. 1 and 2, also can be plural first screws 16.

Because die shank 11 directly bears the pressure of stamping machine, therefore die shank 11 and drift holder 13 are fixed together by the second screw 17, make die shank 11 and drift holder 13 fix more firm.As illustrated two the second screws 17 in Fig. 1 and Fig. 2, it also can be plural second screw 17.The diameter of the second screw 17 is greater than the first screw 16, can bear larger pressure.

In Fig. 1, drift 12 is T-type structure, and the platform of the upper end of drift 12 is positioned at the surface of drift holder 13, and drift holder 13, upper spring 14 and die 15 are run through in drift 12 lower end.

Upper spring 14 and lower spring 21 play cushioning effect when punching press, are polyurethane spring in the present embodiment.Fixed head 22 is polyurethane fixed head, and the lower spring 21 of polyurethane material directly embeds polyurethane fixed head.Polyurethane material itself has that cost is low, the effect of wearability, ageing-resistant, good springiness and bumper and absorbing shock.

In order to make counterdie more stable, counterdie also comprises base plate 23, and the floor space of base plate 23 is greater than the floor space of fixed head 22, and fixed head 22 is positioned on base plate 23.Holder 22 and base plate 23 are fixed together by the 3rd screw (in Fig. 4 shown in dotted line).

Above-mentioned upper die and lower die parts separately can also removably connect by other means except being connected by screw.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
