Summary of the invention
For overcoming the defective of prior art, the technical problem to be solved in the present invention provided a kind of cover plate need not to dodge and take out product, plate compacted without impression subside, the enough thick Multilayer inclined wedge formula mould that is used for the punching press shaped negative angle structures of cover sheet thickness.
Technical scheme of the present invention is: this Multilayer inclined wedge formula mould for the punching press shaped negative angle structures, it comprises the patrix holding pad, upper bolster, die shoe, the whole punch of side, the whole cutter piece of side, cover plate, the patrix holding pad is pressed on the cover board, the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, this mould also comprises the first patrix drive block, the first coaster, the second coaster, the patrix side guide, the first patrix drive block is connected to cover plate by the first coaster of forward translation, and the patrix side guide drives and be pressed in the whole punch of side top by being installed in the second supratrochlear nitrogen spring.
Because the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, thereby the top oblique in two limits of the piecemeal line of cover plate and the whole punch of side and negative angle, and cover plate is movable, take out again the whole punch of side so realized taking out first cover plate, so just can make cover plate need not to dodge and take out product; Owing to be provided with the patrix side guide, subside without impression so plate is compacted; Because the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, so cover plate can be done enough thickly.

Fig. 2 is the structural representation of the Multilayer inclined wedge formula mould for the punching press shaped negative angle structures according to the present invention when closed.
The specific embodiment
As shown in Figure 2, this Multilayer inclined wedge formula mould for the punching press shaped negative angle structures, it comprises patrix holding pad 1, upper bolster 2, die shoe 4, the whole punch 7 of side, the whole cutter piece 9 of side, cover plate 6, patrix holding pad 1 is pressed on the cover plate 6, cover plate 6 is parallel with the facade of material returned mouth with the piecemeal line of the whole punch 7 of side, this mould also comprises the first patrix drive block 3, the first coaster 5, the second coaster 10, patrix side guide 11, the first patrix drive block 3 is connected to cover plate 6 by the first coaster 5 of forward translation, and patrix side guide 11 drives and be pressed in the whole punch of side 7 tops by the nitrogen spring that is installed on the second coaster 10.
Because the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, thereby the top oblique in two limits of the piecemeal line of cover plate and the whole punch of side and negative angle, and cover plate is movable, take out again the whole punch of side so realized taking out first cover plate, so just can make cover plate need not to dodge and take out product; Owing to be provided with the patrix side guide, subside without impression so plate is compacted; Because the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, so cover plate can be done enough thickly.
Preferably, on the cover board also be provided with on earth cushion block.Will be perpendicular to the stressed die shoe bottom surface that is delivered to of the direction Z of cover plate by the whole punch 7 of side, cover plate bears the situation of pressure-plate-force significantly to be improved.Avoided conventional template, fully unsettled at Z direction cover plate, when being subject to the pressure of patrix holding pad, the problem of cover plate distortion even fracture.
Preferably, be provided with counterdie side guide 8 in the side of the whole punch of side.Before 9 work of the whole cutter piece of side, with the plate compression of shaping zone afterbody, have suffered in the journey in side, plate be tighten controlled.Efficiently solve the wrinkling problem in shaping zone that causes because of side whole position free forming.
