Abstract
The utility model discloses a stamping forming mold comprising an upper mold seat, a lower mold seat, a binder ring connected with a cylinder, a pressing core, a convex mold and a concave mold. The upper mold seat and the concave mold below the same are connected with each other through a guide pressing plate, a driving block is arranged on the lower mold seat, the concave mold and the driving block are movably connected into an inclined wedge through a forced return device, the bottom portion of the concave mold is provided with a first step face, and the top portion of the binder ring is provided with a second step face engaged with the first step face. With the adopted structure, the stamping forming mold has the advantages that 1, forming precision of strength steel plate parts is increased so as to shorten period of machine debugging and period of mold development, 2, production cost is reduced, and 3, the mold has simple structure and convenient use.
Description
Technical field
The utility model relates to the technical field of pressure technological equipment for making, particularly a kind of punch-forming mold.
Background technology
Along with in the car load energy-saving and emission-reduction, the more and more strict laws and regulations requirement in collision safety aspect drives down, the ratio row that high-strength steel sheet accounts in body of a motor car exploitation manufacture process are more and more higher, strength grade is also more and more stronger, because the particularity of high strength steel sheet metal forming, the stamping parts dimensional accuracy that traditional drawing and moulding mould that is applied to general steel plate is produced is relatively poor, and warpage, phenomenons such as resilience are commonplace, the beam-like part of some high-strength steel sheets particularly, quality to body in white plays critical effect, but phenomenons such as resilience warpage directly influence the dimensional accuracy of body in white, and have increased the cycle of vehicle body debugging and the cycle of mould development greatly.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of formed precision that can improve the high-strength steel sheet part, and then shortens the punch-forming mold in the cycle of cycle of vehicle body debugging and mould development.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of punch-forming mold, it comprises upper bolster, die shoe, the blank holder that is connected with cylinder, binder core, punch and die, be connected by the pressing plate that leads between the die of described upper bolster and its below, described die shoe is provided with drive block, described die flexibly connects into an oblique contract with drive block by forcing return facilities, the bottom of die is the first step face, the second step face of the top of blank holder for matching with the first step face.
Described upper bolster is provided with a cavity, described upper bolster with its below the binder core between be connected by nitrogen spring and the breaker bolt that runs through cavity.
Described punch is fixed on the die shoe, and the lower surface of the upper surface of described punch and binder core is provided with the gap between corresponding setting and the two.
Described blank holder is arranged in the space that forms between punch and the drive block.
The utility model adopts said structure, has the following advantages: 1, improved the formed precision of strength steel sheet part, and then the punch-forming mold in the cycle of the cycle of shortening vehicle body debugging and mould development; 2, reduced production cost; 3, simple in structure, easy to use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the utility model structural representation;
In Fig. 1,1, upper bolster; 2, die shoe; 3, cylinder; 4, blank holder; 5, binder core; 6, punch; 7, die; 8, guiding pressing plate; 9, drive block; 10, force return facilities; 11, first step face; 12, second step face; 13, plate.
The specific embodiment
A kind of as shown in Figure 1 punch-forming mold, upper bolster 1, die shoe 2, the blank holder 4 that is connected with cylinder 3, binder core 5, punch 6 and die 7, be connected by guiding pressing plate 8 between the die 7 of upper bolster 1 and its below, the pressing plate 8 that leads can make die 7 press down in a certain direction.Die shoe 2 is provided with drive block 9, and die 7 flexibly connects into an oblique contract with drive block 9 by forcing return facilities 10, forces return facilities 10 to make the die 7 that presses down can force backhaul.The bottom of die 7 is a first step face 11, the second step face 12 of the top of blank holder 4 for matching with first step face 11.Upper bolster 1 is provided with a cavity, upper bolster 1 with its below binder core 5 between is connected by nitrogen spring and the breaker bolt that runs through cavity, with guarantee the activity security.Punch 6 is fixed on the die shoe 2, and the lower surface of the upper surface of punch 6 and binder core 5 is provided with the gap between corresponding setting and the two.Blank holder 4 is arranged in the space that forms between punch 6 and the drive block 9.During mold work, cylinder 3 is earlier with blank holder 4 jack-up, die 7 is under the drive of upper bolster 1, move downward and contact plate 13, under the comprehensive function of punch 6, blank holder 4 and die 7, plate 13 tentatively is shaped to ledge structure, here according to first step face 11 for the double step face or for the separate unit terrace gets differently, plate 13 may be molded to double step structure or separate unit stage structure.Along with upper bolster 1 continue press down, die 7 contacts with drive block 9, pressure-pad-force to moulding progressively strengthens, when die 7 continues to press down, the lower surface of binder core 5 compresses the plate 13 of punch 6 upper surfaces, and plate 13 beginning drawing and mouldings are to reach enough pressure-pad-forces, until mould on earth, plate 13 moulding, and guaranteed formed precision.Die 7, blank holder 4 and punch 6 all can be to quench through heat treatment and obtain the high hardness wear-resisting steel alloy, and hardness reaches more than the 62HRC, can improve the service life of mould.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
