Description

High-precision positioning flanging die

Technical Field

The utility model relates to the technical field of molds.

Background

The normal processing technology of the automobile exhaust pipe part comprises the following steps: blanking, stretching, trimming and flanging, wherein the conditions of out-of-tolerance or instability of product side lines and the like are easy to occur after flanging, because of the influence of a product curved surface, the product trimming needs to be repeatedly debugged to produce a qualified product after flanging, and the product appearance size and the product appearance positioning device mutually influence each other. The appearance change of cutting edge at turn-ups process location product position every time before, the appearance positioner of product also must change the position along with, changes every time and all needs form removal die-filling again, and it is too extravagant time.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problem that the automobile exhaust pipe part turn-ups process exists, the utility model provides a high accurate location turn-ups mould.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a high accurate location turn-ups mould, includes upper die base 1 and die holder 6, 1 side-mounting turn-ups terrace die 3 of upper die base, 6 upside installation lower bolster 5 of die holder, and 5 upper portions of lower bolster and 3 matching installation turn-ups terrace die 3 of turn-ups terrace die are located the 3 outside installation lower mould floaters piece 4 of turn-ups terrace die on the lower bolster 5, are equipped with fixed guide way on the lower mould floaters piece 4, place navigation key 11 in the fixed guide way, and navigation key 11 is fixed in fixed guide way through screw 12.

The positioning key 11 is a square positioning key, a slotted hole is formed in the positioning key 11, and the positioning key 11 is fixed in the fixed guide groove through a screw 12 arranged in the slotted hole.

The lower part of the lower die base 6 is provided with a lower cushion block 7, and the lower end of the lower cushion block 7 is arranged on a lower supporting plate 8.

And a stroke limiting column 9 and an outer guide column 10 are arranged between the upper die holder 1 and the lower die holder 6.

The utility model discloses a high accurate location turn-ups mould, through setting up the navigation key, change the product appearance at every turn and only need remove the navigation key, reduce at every turn after the debugging because the produced form removal die-filling time of the reason of location product appearance, improved work efficiency.

Fig. 2 is the utility model discloses high accurate location flanging dies elevation.

In the figure: 1. the device comprises an upper die base, 2, a flanging female die, 3, a flanging male die, 4, a lower die floating block, 5, a lower backing plate, 6, a lower die base, 7, a lower cushion block, 8, a lower supporting plate, 9, a stroke limiting column, 10, an outer guide column, 11, a positioning key, 12 and a screw.

Detailed Description

The utility model discloses a high accurate location turn-ups mould structure is as shown in fig. 1 and fig. 2, including upper die base 1 and die holder 6, 1 side-mounting turn-ups terrace die 3 under the upper die base, 6 upside installation lower bolster 5 of die holder, 5 upper portions of lower bolster and 3 matching installation turn-ups terrace die 3 of turn-ups terrace die, lie in 3 outside installation lower mould floaters 4 of turn-ups terrace die on the lower bolster 5, be equipped with fixed guide way on the lower mould floaters 4, locate key 11 is placed in the fixed guide way, locate key 11 is square locate key, be equipped with the slotted hole on the locate key 11, locate key 11 is fixed in fixed guide way through installing in the downthehole screw 12 of elongated slot. The lower part of the lower die holder 6 is provided with a lower cushion block 7, and the lower end of the lower cushion block 7 is arranged on a lower supporting plate 8. A stroke limiting column 9 and an outer guide column 10 are arranged between the upper die holder 1 and the lower die holder 6.

According to the stamping principle, the front surface of the lower die floating material block 4 is provided with a fixed guide groove of a square positioning key, the fixed guide groove is filled in the square positioning key 11, a long groove hole is cut in the middle line of the square positioning key, the square positioning key 11 positions the position of the raw material shape, the raw material shape changes every time, a die does not need to be disassembled, and the raw material can be accurately positioned only by moving the square positioning key back and forth or left and right. When the positioning device is used, a product to be processed is placed on the flanging male die 3, then the peripheral positioning keys 11 are adjusted to be positioned, the screws are loosened, the positions of the positioning keys in the fixed guide grooves are adjusted through the long slotted holes, and after the positioning key is adjusted, the screws are screwed down, so that a workpiece is positioned. Therefore, the appearance of the trimming at each time is changed, the die does not need to be disassembled, and the square positioning key only needs to move back and forth, so that the later-stage die maintenance cost is reduced and the working efficiency is improved compared with the original structure.
