Abstract
The invention discloses a novel compound punching die. The novel compound punching die comprises an upper die frame and a lower die frame, wherein a striking plate is arranged at the upper end of the upper die frame, a male die fixing plate is arranged at the lower end of the upper die frame, and a stator inner-diameter punch is arranged at the lower end of the male die fixing plate; a stator slot shape punch fixedly connected with the male die fixing plate is arranged on the outer circumference of the stator inner-diameter punch; an inner stripper plate is arranged on the outer circumference of the stator slot shape punch, and a male die is arranged on the outer circumference of the inner stripper plate; the inner stripper plate is fixedly connected with the striking plate in the way that bolts sequentially penetrate the male die fixing plate and the upper die frame; and a female die fixing plate is arranged at the upper end of the lower die frame, a lower jacking 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 circumference of the lower jacking plate, and an outer stripper plate fixedly connected with the female die fixing plate through bolts is arranged on the outer circumference of the female die. The novel compound punching die completes two-time punching actions in the one-step rotor/stator punching process, thereby achieving the purpose of omitting a procedure, reducing loss and improving the efficiency.
Description
Technical field
The present invention relates to a kind of Novel composite water punch die.
Background technology
Motor a kind ofly uses power-equipment widely, produces or all ubiquitous in living, and the demand in market is very big, and the production of production efficiency to motor how improving the stator-rotor iron core in motor has huge meaning.
As one of the critical piece of motor, the ram efficiency of rotor is particularly important, rotor punching press in the past needs 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 completes production by different lathes, namely can produce semi-finished product flowing in each operation, not only time and effort consuming, and certain loss can be caused in handling process, the more important thing is punching press originally labor intensive, each procedure is all have very large pressure to the production of enterprise.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of Novel composite water punch die.
The present invention for achieving the above object, adopts following technical scheme: a kind of Novel composite water punch die, comprises the top mold frame and the corresponding lower mold holder being arranged on bottom that are arranged on top, and described top mold frame is connected with the guide pillar guiding on described lower mold holder by the guide pin bushing be 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, the outer circumference of described diameter of stator bore drift is provided with the stator slot shape drift be fixedly connected with described punch retainer, the outer circumference of described stator slot shape drift is provided with interior stripper, the outer circumference of described interior stripper is provided with punch; Wherein, described interior stripper is fixedly connected with described re-packing by screw bolt passes punch retainer, top mold frame; Described lower mold holder upper end is provided with die block, described die block upper end is provided with lower roof plate, the excircle of described lower roof plate is provided with the die be fixedly connected with described die block, the excircle of described die is provided with the outer stripper that bolt is fixedly connected with described die block.
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, described lower roof plate and described outer stripper are provided with polyurethane rubber.
Beneficial effect of the present invention: the present invention completes the punching press action of twice in a punching course of rotor, reaches the object of minimizing one procedure, Loss reducing, raises the efficiency.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention.
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 1 being arranged on bottom 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 be provided with; Described top mold frame 6 upper end is provided with and re-packs 11, and its lower end is provided with punch retainer 7; Described punch retainer 7 lower end is provided with diameter of stator bore drift 8, the outer circumference of described diameter of stator bore drift 8 is provided with the stator slot shape drift 10 be fixedly connected with described punch retainer 7, the outer circumference of described stator slot shape drift 10 is provided with interior stripper 9, the outer circumference of described interior stripper 9 is provided with punch 12; Wherein, described interior stripper 9 11 to be fixedly connected with described re-packing by screw bolt passes punch retainer 7, top mold frame 6, namely forms rigidity pusher.Described lower mold holder 1 upper end is provided with die block 2, described die block 2 upper end is provided with lower roof plate 3, the excircle of described lower roof plate 3 is provided with the die 14 be fixedly connected with described die block 2, the excircle of described die 14 is provided with the outer stripper 13 that bolt is fixedly connected with described die block 2.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.Described lower roof plate 3 and described outer stripper 13 are provided with polyurethane rubber.
During work, compound press tool of the present invention is fixed on common open type punch press, in the process that slider of punch declines, 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 descending, diameter of stator bore drift 8 and the internal diameter of die 14 interact and form second time punching press again, complete the work that the shaping and stator slot shape waste material of stator punching is separated with rotor diameter, rotor mating plate heads in patrix by lower roof plate 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, create conditions for billot moves, slide block is got back on forcing press after limit, and the bar of beating on slide block acts on dozen rod, and the work of rigidity pusher is descending, by stator punching and rotor disk ejection die, complete whole punching course.Add two times punch function in this punch die, in a punching stroke, stator punching not only can be made shaping, and stator slot shape waste material can be made to be separated, by the product simplification to twice originally wanting three punching presses just can complete from rotor punching external diameter.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
