Abstract

The utility model provides a stamping and cutting die for sliding doors of automobiles. The stamping and cutting die comprises an upper die holder and a lower die holder. Upper trimming cutters corresponding to the shape of an outer plate of a front door of an automobile are arranged on the upper die holder, lower trimming cutters corresponding to the upper trimming cutters are arranged on the lower die holder, an upper cutter corresponding to the integral contour of a joint of a left sliding door and a right sliding door of the outer plate of the front door of the automobile is arranged on the upper die holder, and a lower cutter corresponding to the upper cutter is arranged on the lower die holder. The stamping and cutting die has the advantages that cutting operation can be completed in a working procedure, flanging operation and trimming operation can be completed in a working procedure, accordingly, working procedures are reduced, the stamping production cost is lowered, and expense on a set of dies can be reduced.

Description

Mould is cut in the automobile sliding door punching press

Technical field

The utility model relates to a kind of production mould of automobile sliding door outside plate.

Background technology

Fig. 1 is a kind of left and right slide outer panel structure figure of minicar, the producer of automobile production at present gets raw material plate by four procedure productions, the first operation is drawing and moulding, second operation work is for cutting the limit, three process is for cutting limit, side flanging, shaping, the 4th procedure side flanging and positive flange.wherein, as shown in Figure 2, the limit of cutting in second operation work comprises junction 22 incisions of left and right slide outside plate 2 a part of, be divided into cut 221 ' and connecting portion 222 ', the limit of cutting of three process comprises remaining connecting portion 222 ' slitting-up with left and right slide outside plate, so left and right slide outside plate can separate, that is to say, present incision technique is divided into not to be completed in the two procedures of second operation work and three process, the limited length of the cutter that is used for incision that its second operation work and three process use, because the slit edge edge also needs flange, cause side flanging also need carry out step by step, namely, make in three process and the 4th procedure and all want side flanging, make operation numerous and diverse, every procedure needs again a corresponding mould, therefore number of molds is also more, not only have a strong impact on production efficiency, also increased die cost.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of automobile sliding door punching press to cut mould, will cut in a procedure and complete, flange and deburring also can be completed in a procedure, reach the reduction operation, reduce the punching production cost, and can also reduce by a mold expense.

The utility model is achieved in that a kind of automobile sliding door punching press incision mould, comprise upper bolster and die shoe, described upper bolster is provided with cuts the limit cutter on corresponding with automobile front door outside plate shape, described die shoe be provided with on cut the limit cutter corresponding under cut the limit cutter, also be provided with corresponding to the overall profile of the slide junction, left and right of automobile front door outside plate on described upper bolster and cut cutter on one, arrange corresponding to described upper incision cutter on described die shoe and cut cutter.

Described die shoe is provided with a garbage collection chute at a place, outer end of described lower incision knife tool respectively.

The utility model has the advantage of: mould is cut in the automobile sliding door punching press, to cut cutter and cut the limit cutter and be located at in mould, incision technique is completed in same procedure, be equivalent to the incision technique in original three process is merged in the deburring technique of the second operation, the flange of such the 4th operation and side flanging just can merge with flange and the deburring of the 3rd operation, reach the purpose of reduction one operation, reduce the punching production cost, and can also reduce by a mold expense.

The specific embodiment

See also Fig. 1, Fig. 3 to shown in Figure 5, mould 1 is cut in automobile sliding door punching press of the present utility model, comprise upper bolster 11 and die shoe 12, described upper bolster 11 is provided with cuts limit cutter 111 on corresponding with automobile front door outside plate shape, described die shoe 12 be provided with on cut limit cutter 111 corresponding under cut limit cutter 121, also be provided with corresponding to the overall profile of the slide junction, left and right 22 of automobile front door outside plate on described upper bolster 11 and cut cutter 112 on one, arrange corresponding to described upper incision cutter 112 on described die shoe 12 and cut cutter 122.

Described die shoe 12 is provided with a garbage collection chute (not shown) at a place, outer end of described lower incision knife tool 112.When collecting waste material, can place a garbage collection car at garbage collection chute end and collect.

During use, the automobile front door outside plate 2 that draws is placed on die shoe 12, when instantly pressing die holder 11, upper cut limit cutter 111 and under cut limit cutter 121, completing the limit of cutting of square plate moves, under the acting in conjunction of upper incision cutter 112 and lower incision knife tool 122, can complete the incision action of square plate simultaneously, to realize that automobile front door outside plate 2 is cut limit and incision two procedures.In addition, the corner material of incision may skid off outside board by the garbage collection chute, is collected by the garbage collection car.

The utility model has the advantage of: mould is cut in the automobile sliding door punching press, to cut cutter and cut the limit cutter and be located at in mould, and it is corresponding with the overall profile of the junction of left and right slide to cut cutter, incision technique is completed in same procedure, be equivalent to the incision technique in original three process is merged in the deburring technique of the second operation, the flange of such the 4th operation and side flanging just can merge with flange and the deburring of the 3rd operation, reach the purpose of reduction one operation, reduce the punching production cost, and can also reduce by a mold expense.

Although more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
