Abstract
The utility model discloses a lower die of a filter spiral plate punching die. The lower die comprises a center positioning shaft, a lower die plate and a lower die holder, wherein the center positioning shaft, the lower die plate and the lower die holder are connected in sequence. An annular groove is formed in the top of the lower die plate with the center positioning shaft as the circle center and correspondingly matched with a punching pin of an upper die of the punching die, the design of the annular groove is used for replacing a traditional design of a cylindrical groove formed in the lower die plate, the step of alignment between the punching pin and the cylindrical groove is omitted in the using process, time and labor are saved, and production efficiency is improved; the problem that the punching pin is damaged due to alignment errors in the punching process is avoided; a filter spiral plate is formed in the annular groove in a semi-open extrusion mode, so that convex point forming force is greatly reduced, forming is easy to perform, the loss of the punching pin is small, stress on a punching machine is reduced, and overall performance of the punching machine is improved.
Description
Technical field
The utility model relates to mould applications, specifically a kind of counterdie of filter spiral plate diel.
Background technology
Filter spiral plate is one of important composition parts of cleaner, on the rotatable filter spiral shell plate of projection-welding structure, and must punching press salient point; The diel adopting is at present, at patrix, red needle is set, the column type groove that counterdie setting is corresponding with red needle, and during use, spiral shell plate is placed on counterdie, relies on the Pressing Deformation of red needle to spiral shell plate, makes spiral shell plate produce cylindrical salient point.But this diel, manufacturing the centering link that must consider red needle and column type groove when installing, is wasted time and energy, if deviation slightly, the salient point that not only punching press does not go out to want also can damage red needle; And when carrying out punching press, spiral shell plate is subject to cold extrusion and forms cylindrical salient point in column type groove, the required distortion external force of moulding is larger, easy-formation not, and red needle consume is serious.
Utility model content
The purpose of this utility model is to provide a kind of counterdie of filter spiral plate diel, this counterdie has saved the centering link with patrix red needle when installing and using, the problem that causes red needle to damage due to correct error in the time of can avoiding punching press, easy moulding during punching press, reduce red needle loss, time saving and energy saving, enhance productivity.
The utility model solves the technical scheme that its technical problem adopts:
A counterdie for filter spiral plate diel, comprises successively connected centralized positioning axle, lower bolster and die shoe, take centralized positioning axle and as the center of circle, ring shaped slot is set, the mutual corresponding matching of red needle of ring shaped slot and upper die of stamping die in described lower bolster top.
The beneficial effects of the utility model are, with ring shaped slot, be substituted in the traditional design that lower bolster arranges column type groove, during use, saved the centering link of red needle and column type groove, time saving and energy saving, enhance productivity, problem simultaneously that caused red needle to damage due to correct error while also having avoided punching press; Filter spiral plate is semi open model extrusion modling in cannelure, and salient point forming force is reduced greatly, easily moulding, and red needle consume is little, has reduced the stressed of punch press, has improved the overall performance of punch press.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the use schematic diagram of the utility model embodiment;
Fig. 2 is the top view of counterdie in Fig. 1.
The specific embodiment
Shown in Fig. 1 and Fig. 2, the counterdie of a kind of filter spiral plate diel that the utility model provides, comprise successively connected centralized positioning axle 8, lower bolster 9 and die shoe 10, between lower bolster 9 and die shoe 10, be also provided with backing plate 13, die shoe 10 both sides, top are provided with locating dowel 11; Take centralized positioning axle 8 ring shaped slot 12 be set as the center of circle in lower bolster 9 tops, the mutual corresponding matching of red needle 5 of ring shaped slot 12 and patrix.
The upper die structure coordinating with counterdie is varied, and the present embodiment provides a kind of patrix, comprises connected successively die shank 1, upper bolster 2 and patrix material returned part 3; Patrix material returned part 3 mainly consists of polyurethane adhesive 7, and patrix material returned part 3 bottom centre are provided with the center coordinating with centralized positioning axle 8 and dodge hole 6, take center and dodge hole 6 and as the center of circle, be provided with one group of red needle 5 with ring shaped slot 12 mutual corresponding matching in patrix material returned part 3 bottoms; Upper bolster 2 two bottom sides are provided with the location guide pin bushing 4 coordinating with locating dowel 11.
During use, patrix is fixed on by die shank 1 on the slide block of punch press, and counterdie is fixed on work bench of punch press by pressing plate; Filter spiral plate is placed on the end face of lower bolster 9 by centralized positioning axle 8; Start punch press, patrix starts to press down, and in this process, dodge in hole 6 at centralized positioning axle 8 insertion centers, and locating dowel 11 is inserted in the guide pin bushing 4 of location, plays guide effect; After patrix material returned part 3 contact filter spiral plates, stress deformation, red needle 5 is pressed into filter spiral plate top surface, spiral shell plate is got into 12 li of the cannelures of lower bolster 9, thereby stamp out salient point at Luo Banshang, during punching press, backing plate 13 plays the cushioning effect to counterdie, after this patrix has lifted stamping procedure one time.
Owing to being substituted in ring shaped slot 12 traditional design that lower bolster 9 arranges column type groove, so saved the centering link of red needle and column type groove when installing and using, time saving and energy saving, improved production efficiency, the problem that has caused red needle to damage due to correct error while also having avoided punching press simultaneously; Filter spiral plate, in the interior semi open model extrusion modling of cannelure 12, reduces salient point forming force greatly, easily moulding, and red needle consume is little, has reduced the stressed of punch press, has improved the overall performance of punch press.
The above, be only preferred embodiment of the present utility model, not the utility model done to any pro forma restriction; Any those of ordinary skill in the art, do not departing from technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore; every content that does not depart from technical solutions of the utility model; according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, be equal to replacements, equivalence changes and modify, all still belong in the scope that technical solutions of the utility model protect.
