Abstract

The utility model discloses an inverted dissectible trimming die, and relates to a stamping die. The inverted dissectible trimming die comprises an upper die holder and a lower die holder, wherein a trimming male die is arranged on the upper surface of the lower die holder; a drawing male die is arranged on the upper end surface of the trimming male die; the diameter of the drawing male die is smaller than that of a working part of the trimming male die; a female die is arranged at a position, which corresponds to the trimming male die, of the lower surface of the upper die holder; a pressure plate is arranged in a female die hole of the female die and can slide relative to the female die hole; a beating rod is arranged at the upper end of the pressure plate; and the upper end of the beating rod is connected to the inside of the upper die holder through a pressing spring. Drawing forming and trimming treatment of products can be realized in the die, so that work efficiency is improved; because only the inverted dissectible trimming die is required, the cost for the die is reduced; and moreover, the products are not required to be positioned repeatedly, so that the accuracy of the products is improved.

Description

Flip-over type squeezes cuts trimming die
Technical field
The utility model relates to a kind of diel, relates in particular to the crowded trimming die of cutting of a kind of flip-over type.
Background technology
Pull and stretch is a kind of common mechanical processing technique, is to claim again to draw with the pressing formation worker ﹐ that plants that rushes that the plane slab is made cup shell.Can make the hollow element of flanged and other complicated shapes of Yuan Tong Xing ﹑ Qiu Xing ﹑ Zhui Xing ﹑ He Xing ﹑ Jie Ti Xing ﹑ by pull and stretch.Its shaping generally is to finish by Drawing Die, its oral area generally all not concordant lug can occur after drawing part is shaped, the processing of need to cutting edge, it generally is to select edger that existing drawing part is cut edge, and the processing that existing edger can only be cut edge, after drawing part is through the processing of Drawing Die pull and stretch, it need to be taken out from Drawing Die, putting into edger cuts edge again, operation is very inconvenient like this, has reduced operating efficiency, has increased die cost, and need resetting, affected the precision of product.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of flip-over type to squeeze and has cut trimming die, can in a mold, realize the drawing and forming of product and the processing of cutting edge, improved operating efficiency, only need a mold, reduced die cost, and do not needed the product resetting has been improved the precision of product.
The technical solution of the utility model is: a kind of flip-over type squeezes cuts trimming die, comprise upper bolster and die shoe, the die shoe upper surface is provided with the side cut punch, side cut punch upper surface is provided with the pull and stretch punch, the diameter of pull and stretch punch is less than the diameter of side cut punch working portion, the position that the upper bolster lower surface is corresponding with the side cut punch is provided with die, be provided with holding pad in the die hole of die, holding pad relatively die hole slides, the holding pad upper end is provided with makes bar, beats the bar upper end and is connected in the upper bolster by the binder spring.
As preferably, described pull and stretch punch upper surface has out vent hole, is socketed with top board on the side cut punch, and the top board lower end is provided with push rod, and the push rod lower end is connected with the bullet apical organ.
As preferably, upper bolster and die shoe adopt the Q235 steel to make, and the die hole lower edge has fillet, and the gap between die and the side cut punch is 0.02-0.04mm.
The beneficial effects of the utility model are: the utility model can successively be finished the pull and stretch of product and the processing of cutting edge, when forcing press moves down, die contacts with the pull and stretch punch first, finish the drawing and forming of product, when forcing press continues to move down, die contacts with the side cut punch, finish the side cut processing of product, do not need to use two molds, reduced die cost, workpiece behind the pull and stretch does not need to take out can finish side cut, improved working (machining) efficiency, saved time and cost, the workpiece behind the pull and stretch does not need resetting, improved the precision of product, very practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of flip-over type squeezes cuts trimming die, comprise upper bolster 6 and die shoe 9, in the present embodiment, as preferably, described upper bolster 6 and die shoe 9 adopt the Q235 steel to make good combination property, long service life.Die shoe 9 upper surfaces are provided with side cut punch 8, side cut punch 8 upper surfaces are provided with pull and stretch punch 3, the diameter of pull and stretch punch 3 is less than the diameter of side cut punch 8 working portions, and in the present embodiment, pull and stretch punch 3 differs two workpieces with the diameter of side cut punch 8.Upper bolster 6 lower surfaces and side cut punch 8 corresponding positions are provided with die 7, be provided with holding pad 4 in the die hole of die 7, holding pad 4 relatively die hole slides, and holding pad 4 upper ends are provided with makes bar 5, beats bar 5 upper ends and is connected in the upper bolster 6 by the binder spring.When forcing press was descending, holding pad 4 with Work-sheet pressing, guaranteed the positioning accuracy of workpiece under the effect of binder spring, avoid workpiece wrinkling.
In the present embodiment, as preferably, described pull and stretch punch 3 upper surfaces have out vent hole, when punching press, pass into compressed air in going out vent hole, workpiece can be blown out, and prevent that effectively workpiece from sticking to pull and stretch punch 3 surfaces.Be socketed with top board 2 on the side cut punch 8, top board 2 lower ends are provided with push rod 1, and push rod 1 lower end is connected with the bullet apical organ.When punching press, top board 2 withstands the edge of work by playing apical organ, makes side cut more convenient.
In the present embodiment, as preferably, the die hole lower edge has fillet, and workpiece wall has been improved the surface quality of workpiece by drawing crack when having avoided pull and stretch.Gap between die 7 and the side cut punch 8 is 0.02-0.04mm, has guaranteed the side cut precision of workpiece.
