Abstract
The utility model discloses a novel compound punching die. The novel compound punching die comprises an upper formwork and a lower formwork; a striking plate is arranged at the upper end of the upper formwork; a male die fixing plate is arranged at the lower end of the upper formwork; a stator inner diameter punch is arranged at the lower end of the male die fixing plate; a stator groove shape punch fixedly connected with the male die fixing plate is arranged on the outer periphery of the stator inner diameter punch; an inner stripper plate is arranged on the outer periphery of the stator groove shape punch and a male die is arranged on the outer periphery of the inner stripper plate; the inner stripper plate is fixedly connected with the striking plate by use of a bolt orderly penetrating through the male die fixing plate and the upper formwork; a female die fixing plate is arranged at the upper end of the lower formwork, a lower ejector plate is arranged at the upper end of the female die fixing plate, a female die fixedly connected with the female die fixing plate is arranged on the outer periphery of the lower ejector plate, and an outer stripper plate fixedly connected with the female die fixing plate by use of a bolt is arranged on the outer periphery of the female die. The novel compound punching die has the advantages that twice punching actions are completed in once punching process of a stator and a rotor so that one step can be reduced, and therefore, the loss is reduced and the efficiency is improved.
Description
Technical field
The utility model relates to a kind of Novel composite water punch die.
Background technology
Motor is a kind of power-equipment very widely that uses, produce or live in all ubiquitous, the demand in market is very big, the production efficiency that how to improve the stator-rotor iron core in motor has huge meaning to the production of motor.
As one of critical piece of motor, the ram efficiency of rotor is particularly important, rotor punching press in the past need to be completed by 3 steps: 1, blanking, 2, stator slot shape punching press, 3, rotor slot shape punching press, in this production process, each step is to complete production by different lathes, namely in each operation, can produce semi-finished product flows, not only time and effort consuming, and can cause certain loss in handling process, and the more important thing is that punching press was exactly labor intensive originally, each procedure is all to have very large pressure to the production of enterprise.
Utility model content
The utility model object is that the defect existing for prior art provides a kind of Novel composite water punch die.
The utility model for achieving the above object, adopt following technical scheme: a kind of Novel composite water punch die, comprise the top mold frame and the corresponding lower mold holder that is arranged on bottom that are arranged on top, described top mold frame is connected with the guide pillar guiding on described lower mold holder by the guide pin bushing being provided with; Described top mold frame upper end is provided with and re-packs, and its lower end is provided with punch retainer; Described punch retainer lower end is provided with diameter of stator bore drift, in the outer circumference of described diameter of stator bore drift, be provided with the stator slot shape drift being fixedly connected with described punch retainer, in the outer circumference of described stator slot shape drift, be provided with interior stripper, in the outer circumference of described interior stripper, be provided with punch; Wherein, described interior stripper by screw bolt passes punch retainer, top mold frame with described in re-pack and be fixedly connected with; Described lower mold holder upper end is provided with die block, described die block upper end is provided with lower roof plate, on the excircle of described lower roof plate, be provided with the die being fixedly connected with described die block, on the excircle of described die, be provided with the outer stripper being fixedly connected with described die block by bolt.
Further, the lower end of described stator slot shape drift low go out the lower end 0.6-0.8mm of described diameter of stator bore drift.
Further, on described lower roof plate and described outer stripper, be provided with polyurethane rubber.
The beneficial effects of the utility model: the utility model has completed the punching press action of twice in to rotor punching course, has reached the object that reduces by a procedure, reduces loss, raises the efficiency.
Brief description of the drawings
Fig. 1 structural representation of the present utility model.
Detailed description of the invention
Shown in Fig. 1, be a kind of Novel composite water punch die, comprise the top mold frame 6 and the corresponding lower mold holder that is arranged on bottom 1 that are arranged on top, described top mold frame 6 is connected with guide pillar 5 guiding on described lower mold holder 1 by the guide pin bushing 4 being provided with; Described top mold frame 6 upper ends are provided with and re-pack 11, and its lower end is provided with punch retainer 7; Described punch retainer 7 lower ends are provided with diameter of stator bore drift 8, in the outer circumference of described diameter of stator bore drift 8, be provided with the stator slot shape drift 10 being fixedly connected with described punch retainer 7, in the outer circumference of described stator slot shape drift 10, be provided with interior stripper 9, in the outer circumference of described interior stripper 9, be provided with punch 12; Wherein, described interior stripper 9 by screw bolt passes punch retainer 7, top mold frame 6 with described in re-pack and 11 be fixedly connected with, form rigidity pusher.Described lower mold holder 1 upper end is provided with die block 2, described die block 2 upper ends are provided with lower roof plate 3, on the excircle of described lower roof plate 3, be provided with the die 14 being fixedly connected with described die block 2, on the excircle of described die 14, be provided with the outer stripper 13 being fixedly connected with described die block 2 by bolt.Wherein, the lower end of described stator slot shape drift 10 low go out the lower end 0.6-0.8mm of described diameter of stator bore drift 8.On described lower roof plate 3 and described outer stripper 13, be provided with polyurethane rubber.
When work, compound press tool of the present utility model is fixed on common open type punch press, in the process declining at slider of punch, preferably by the lower end of stator slot shape drift 10 lower than described diameter of stator bore drift 0.6-0.8mm, so just can first contact material and form workmanship, better complete the punching press of stator slot shape.When slider of punch continues when descending, diameter of stator bore drift 8 interacts and forms punching press for the second time again with the internal diameter of die 14, complete the work that stator punching moulding and stator slot shape waste material separate with rotor diameter, lower roof plate heads into rotor mating plate in patrix under the effect of polyurethane simultaneously.Along with slide block return, outer stripper 13 is under the effect of polyurethane, billot is placed on higher than lower mold holder 1 plan-position, for moving, billot creates conditions, slide block is got back on forcing press after limit, and the bar of beating on slide block acts on and plays rod, and the work of rigidity pusher is descending, by stator punching and rotor disk ejection die, complete whole punching course.In this punch die, increase two times punch function, in a punching stroke, not only can make stator punching moulding, and can make stator slot shape waste material separate from rotor punching external diameter, by the product simplification to twice of originally wanting three punching presses just can complete.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
