Abstract
The utility model discloses a deep drawing die. The deep drawing die comprises a stock guide, a discharging plate, a material ramming rod, a convex concave die, an upper die base, a lower die base, an ejector rod, a blank holder, a deep drawing convex die and a blanking concave die. The material ramming rod is arranged in the middle of the whole die, penetrates through the upper die base and straight extends to the lower die base, and when the material ramming rod penetrates through a hemispheric die from the middle, the radius of the hemispheric die becomes small. The deep drawing convex die is arranged at the lower end of the hemispheric die and connected with the side edge of the material ramming rod, the convex concave die is arranged outside the hemispheric die, the blank holder is arranged at the lower end of the convex concave die and connected with the ejector rod, the discharging plate penetrates through the convex concave die, the stock guide is arranged at the lower end of the discharging plate, and the blanking concave die is arranged at the lower end of the guide stock. The deep drawing die is simple in structure, short in manufacturing period and low in cost, prevents blank holder force from increasing along with the increase of a stroke, and is not only applicable to occasions with small blank holder force but also applicable to occasions with large blank holder force.
Description
Technical field
The utility model relates to mould applications, relates in particular to a kind of cupping tool.
Background technology
Cupping tool can be divided into cupping tool and follow-up each operation cupping tool first by its process sequence, and the essential distinction between them is the structure of blank holder and the difference on locate mode.The pressing equipment used by drawing die can be divided into again cupping tool for single action press, cupping tool and triple action press cupping tool for double action press, and their essential distinction is the difference of flange fixing installation (elastic blank holding and rigid blank holder).Combination by operation divides, and can be divided into again single operation cupping tool, composite die and step-feeding cupping tool.In addition, also can, by having or not flange fixing installation, be divided into without flanging device cupping tool and flange fixing installation cupping tool etc. is arranged.
In prior art, the cupping tool complex structure, applicability is lower, as be used in the little occasion of pressure-pad-force, just can not be useful in other occasion, a kind of mould of must again redeveloping.In addition, can't carry out strict repeatedly pull and stretch, less pull and stretch or shaping etc. for reduced.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of adaptable cupping tool, and this mould is the applicable little occasion of pressure-pad-force not only, also the applicable large occasion of pressure-pad-force.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of cupping tool, described mould comprises stock guide, stripper, knockout rod, punch-die, upper bolster, die shoe, push rod, blank holder, the pull and stretch punch, blanking die, described knockout rod is located at the middle part of whole mould, through upper bolster, extend to die shoe always, when knockout rod passes the hemispherical mould at middle part, its radius diminishes, hemispherical mould lower end is provided with the pull and stretch punch, described pull and stretch punch is connected with the knockout rod side, hemispherical mould outside is provided with punch-die, described punch-die lower end is provided with blank holder, this blank holder is connected with push rod, described stripper is through punch-die, be provided with stock guide in the stripper lower end, the stock guide lower end is provided with blanking die.
Further, described push rod is placed in the lower end of blank holder.
The beneficial effects of the utility model are: simple in structure, the manufacturing cycle is short, and cost is low, prevents that pressure-pad-force from constantly increasing with the increase of stroke, and this mould is the applicable little occasion of pressure-pad-force not only, also the applicable large occasion of pressure-pad-force.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is elaborated.
Fig. 1 is the utility model structural representation.
Each mark title in figure: 1-stock guide; The 2-stripper; The 3-knockout rod; The 4-punch-die; The 5-upper bolster; The 6-die shoe; The 7-push rod; The 8-blank holder; 9-pull and stretch punch; The 10-blanking die.
The specific embodiment
As shown in Figure 1, a kind of cupping tool, described mould comprises stock guide 1, stripper 2, knockout rod 3, punch-die 4, upper bolster 5, die shoe 6, push rod 7, blank holder 8, pull and stretch punch 9, blanking die 10, described knockout rod 3 is located at the middle part of whole mould, through upper bolster 5, extend to die shoe 6 always, when knockout rod 3 passes the hemispherical mould at middle part, its radius diminishes, hemispherical mould lower end is provided with pull and stretch punch 9, described pull and stretch punch 9 is connected with knockout rod 3 sides, hemispherical mould outside is provided with punch-die 4, described punch-die 4 lower ends are provided with blank holder 8, this blank holder 8 is connected with push rod 7, described stripper 2 is through punch-die 4, be provided with stock guide 1 in stripper 2 lower ends, stock guide 1 lower end is provided with blanking die 10.Described push rod 7 is placed in the lower end of blank holder 8.At first drive blank holder 8 during pull and stretch and push down blank, then drive the descending pull and stretch that carries out of pull and stretch punch 9.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present utility model.
