Description
Technical field
The utility model relates to a kind of rotor compound press tool.
Background technology
At present, motor is a kind of use power-equipment very widely, produces or lives all ubiquitously, and the demand in market is very big, how to improve raw-material utilization rate, the production efficiency that how to improve stator-rotor iron core 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, blanking is first billot to be cut into block material, is generally the length that the width of a product is multiplied by several product diameters; And then artificial punching press, so not only efficiency is low, has potential safety hazard, and larger is to improve stock utilization.Even if select deep throat well punch ram, its mould must be the structure that there is no guide pillar, if guide pillar is housed, can cause the waste material of punching press to conflict mutually with guide pillar, and cannot punching press, guide pillar is not installed so just very high to the required precision of lathe slide block, not so mould can cause the excessive properties of product that affect of product burr because the gap of slide block causes mould seaming phenomenon, and baroque compound mould does not have the guiding of guide pillar cannot use at all.
Utility model content
The utility model object is that the defect existing for prior art provides a kind of rotor compound press tool, in to workpiece punching press, waste material can be excised, solve can not the interlock bottleneck of punching press of rotor gangdie, not only improved production efficiency, more saved material.
The utility model for achieving the above object, adopt following technical scheme: a kind of rotor compound press tool, 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; The upper end of described top mold frame has been bolted and has re-packed, and its lower end is provided with punch retainer; Described punch retainer lower end is provided with punch, and the inner side of described punch is provided with interior stripper, and the inner side of described interior stripper arranges the flute profile drift being fixedly connected with described punch retainer; Described lower mold holder upper end is provided with die block, and described die block upper end is provided with die, is provided with the outer stripper being fixedly connected with described die block on the excircle of described die; Between described top mold frame and lower mold holder, described in distance, the location of half product diameter of punch center is provided with for excising the cutter assembly of waste material.
Further, on the length direction of described cutter assembly, be formed with the cut surface at ° angle, 40 ° of angles to 70.
Further, described cutter assembly comprises the cutter being arranged in described top mold frame, and is arranged on the bottom knife matching with described cutter on described lower mold holder.
Further, the lower end of described cutter is concordant with the lower end of described punch, and the upper end of described bottom knife is concordant with the upper end of described die.
The beneficial effects of the utility model: compound press tool of the present utility model can excise waste material in stamping products, have solved can not the interlock bottleneck of punching press of rotor compound press tool, have not only improved production efficiency, have more saved material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Shown in Fig. 1, be a kind of rotor compound press tool, 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 punch 8, and the inner side of described punch 8 is provided with interior stripper 9, and the inner side of described interior stripper 9 arranges the flute profile drift 10 being fixedly connected with described punch retainer 7; Described lower mold holder 1 upper end is provided with die block 2, and described die block 2 upper ends are provided with die 14, are provided with the outer stripper 13 being fixedly connected with described die block 2 on the excircle of described die 14; Wherein, between described top mold frame 6 and lower mold holder, the location at half product diameter of distance described punch center is provided with for excising the cutter assembly of waste material.On the length direction of described cutter assembly, be formed with the cut surface (60 ° angles for best) at ° angle, 40 ° of angles to 70, more convenient like this waste material of product got off from blade landing.Wherein, described cutter assembly comprises the cutter 151 being arranged in described top mold frame 6, and is arranged on the bottom knife 152 matching with described cutter 151 on described lower mold holder 1.During design, preferably that the lower end of described cutter 151 is concordant with the lower end of described punch, the upper end of described bottom knife 152 is concordant with the upper end of described die 14; Be conducive to so the once complete excision of blade to waste material.
Operation principle: rotor compound press tool of the present utility model is fixed on open type punch press, silicon steel sheet raw material are fixed on feeder table top, with cylinder, material is clamped, start by setup program product to carry out punching press.Wherein, first row is punching press to the right along a straight line, second row is stamped workpieces between two adjacent circles of first row, " triangle " between two circles can be used like this, and second row is punching press left, now first row has been the complete product waste material of punching press, and toward side shifting after mould, in punching press second row product, the cutter assembly arranging in punch die can complete cutting product waste material simultaneously, when waste material reaches certain quantity, just can product waste material be pulled out in mould with instrument, so circulation.
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 modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
