The specific embodiment
For describing technical characterictic of the present utility model and effect in detail, and can realize according to the content of this description, below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated.
Referring to Fig. 3 and Fig. 4, spacing contour structure for a kind of multistation progressive die of the present utility model, multistation progressive die comprises upper bolster 21 and is arranged in the stripper 28 of these upper bolster 21 belows, and this spacing contour structure comprises contour sleeve 23, unloading bolt 27, spring 22, contour limited block 25 and packing ring 26, the limited block through hole 25-1 on contour limited block 25 with up/down perforation, two fixed via 25-2 on the upper surface of contour limited block 25 with downward perforation, these two fixed via 25-2 are distributed in the both sides that limited block through hole 25-1 is relative and are counter sink, certainly, fixed via 25-2 also can be more than two, now, these fixed vias 25-2 is around limited block through hole 25-1 periphery circumferential arrangement, circumferentially be evenly arranged better, limited block hold-down screw 24 be passed down through after fixed via 25-2 with stripper 28 on screw 28-3 be spirally connected fastening, thereby contour limited block 25 is fixed on the upper surface of stripper 28, the spiral shell head of limited block hold-down screw 24 is imbedded in the counterbore head of fixed via 25-2 completely, the interference of the spiral shell head of limited block hold-down screw 24 to upper bolster 21 during with elimination multistation progressive die, except the above-mentioned upper surface that contour limited block 25 is fixed on to stripper 28 by this fixed form of limited block hold-down screw 24 upper outside, can also adopt other modes, as welding, on the lower surface of stripper 28, there is counterbore 28-1, on the bottom surface of counterbore 28-1, there is up/down perforation the guide through hole 28-2 corresponding with limited block through hole 25-2, contour sleeve 23 lower ends are sleeved on the interior 28-2 of guide through hole and are slidably matched with this guide through hole 28-2 after being passed down through limited block through hole 25-2, between the inwall of this limited block through hole 25-2 and the respective external wall of this contour sleeve 23, form the spatial accommodation 29 of ring-type, spring 22 is arranged in spatial accommodation 29 and is sleeved in the respective external wall of contour sleeve 23, unloading bolt 27 is spirally connected fastening with upper bolster 21 after the endoporus through counterbore 28-1, packing ring 26, contour sleeve 23 from the bottom to top successively, packing ring 26 can increase the area of unloading bolt 27 heads, to guarantee that unloading bolt 27 can compress contour sleeve 23, thereby contour sleeve 23 is fixed on upper bolster 21, and this unloading bolt 27 is soket head cap screw, the external diameter of packing ring 26 is greater than the internal diameter of guide through hole 28-2 and is less than the internal diameter of counterbore 28-1, thereby in the time of like this can also be in die opening state when spring 22 is compressed the upper surface of packing ring 26 and the bottom surface of counterbore 28-1 contact stripper 28 and on parts hold in order to avoid down drop, the spiral shell head of unloading bolt 27 and packing ring 26 all can be embedded in counterbore 28-1, to reduce the interference to stripper 28.
It should be noted that, above-mentioned be arranged in spatial accommodation 29 except spring 22, can also be other elastomeric elements, as elastic caoutchouc cylinder.
During construction, by the spacing contour structure of the above-mentioned multistation progressive die of many covers, upper bolster 21 is connected with stripper 28, because the length of every contour sleeve 23 is identical, length after can making every spring 22 compressed is in full accord, to guarantee that stripper 28 is horizontal when the work and keeps horizontal movement, meanwhile, stripper 28 dischargings are more steady.Contour limited block 25 is when multistation progressive die is closed, and the distance between restriction stripper 28 and upper bolster 21 is to protect other parts or device to exempt from damage.Open Side Down at the spiral shell head of unloading bolt 27, to be positioned at counterbore 28-1 and this counterbore 28-1, construction tool can convenient stretch into from below to be tightened in counterbore 28-1 or unscrews unloading bolt 27, therefore adjust binder after mould is arranged on forcing press, stripping force is very convenient.
Above with reference to embodiment, the utility model being have been described in detail, is illustrative and not restrictive, in the variation and the modification that do not depart under the utility model general plotting, all within protection domain of the present utility model.
