Description

Automobile back door sealing strip shaving die

Technical field

The present invention relates to shaving die, especially relate to a kind of shaving die of automobile door weather strip, belong to the technology of die manufacturing field.

Background technology

Fig. 1 is the structural representation of automobile back door sealing strip; Fig. 2 is for doing the A-A profile of Fig. 1 of skeleton with bar section of stainless steel; Fig. 3 is the structural representation that needs the special-shaped automobile back door sealing strip of side cut;

As shown in Figure 1 to Figure 3, automobile back door sealing strip is to be skeleton with bar section of stainless steel D, pour into a mould profiled seal rubber C then and form, the automobile back door sealing strip after the moulding need be with a unnecessary limit excision, and traditional method for cutting edge need act on the operation of just cutting edge simultaneously by upper die and lower die, and the special construction of automobile back door sealing strip, make above-mentioned side cut mode very inconvenient, and need cutting at twice, if adopt once cutting, then will cause cutting knife too wide, cutting knife is easy to distortion.

Summary of the invention

In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of automobile back door sealing strip shaving die of simple in structure, easy to operate, high efficiency.

The present invention is achieved through the following technical solutions:

A kind of automobile back door sealing strip shaving die, it is characterized in that, comprise the punch press top shoe, be arranged on the punch press top shoe and form the re-packing of T shape structure, counterdie and cutting knife with the punch press top shoe, wherein, counterdie is provided with stop screw, the outside of stop screw then is with spring, and spring is arranged in the chamber of above-mentioned cutting knife bottom simultaneously.

Further, the cutting knife material is the DC53 steel, and its hardness (HRC) is 53~58, and its edge of a knife angle is 25 °.

The invention has the beneficial effects as follows: the present invention is simple in structure, and is easy to operate, and only needs one can be with the limit excision of special-shaped automobile back door sealing strip cutting knife, improved operating efficiency greatly, reduce one-tenth and produced cost, and because the cutting knife of its use is special-shaped cutter, so the quality of the product of its cutting is good.

The specific embodiment

Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:

Fig. 4 is the structural representation of one embodiment of the invention; Fig. 5 is the I part enlarged drawing of Fig. 4; Fig. 6 is the working state schematic representation of one embodiment of the invention.

Extremely shown in Figure 6 as Fig. 4: automobile back door sealing strip shaving die, comprise punch press top shoe 7, be arranged on the punch press top shoe 7 and with punch press top shoe 7 form T shape structures re-pack 3, counterdie 4 and cutting knife 2, wherein, counterdie 4 is provided with stop screw 6, the outside of stop screw 6 then is with spring 5, spring 5 is arranged in the chamber of above-mentioned cutting knife 2 bottoms simultaneously, cutting knife 2 materials are the DC53 steel, its hardness (HRC) is 53~58, and its edge of a knife angle is 25 °, in the present embodiment, the hardness of cutting knife 2 is 56.

In the side cut process, at first adjust the stop screw 6 of spring 5, special-shaped automobile back door sealing strip 1 can also be located in free suction, punch press top shoe 7 is descending then, re-pack and 3 push down cutting knife 2 and move down, carry out die-cut simultaneously, unnecessary limit excision with special-shaped automobile back door sealing strip 1, the waste material that downcuts is discharged from row's slug hole, and at this moment, spring 5 is compressed simultaneously, after treating that punch press top shoe 7 is up, compressed spring 5 promotes cutting knife 2 and resets, and the automobile back door sealing strip after the cutting is extracted out, finishes the operation of cutting edge.

The present invention is simple in structure, and is easy to operate, utilizes stainless steel insert D as support, only with excising once limit that can sealing strip is unnecessary cutting knife; In addition, used cutting knife is special-shaped cutter, and its material is the DC53 steel, so the edge of a knife of cutting knife 2 is very sharp, and cutting is easy and speed is fast.

Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
