Abstract
A fault detection mechanism for a progressive die of a motor core comprises a minitype travel switch, a fault feeler lever, a fault sliding head and a fault correcting pin, wherein the minitype travel switch, the fault feeler lever, the fault sliding head and the fault correcting pin are connected with a machine tool controller. The minitype travel switch is fixed to an upper die base provided with a guide pin. The trigger end of the minitype travel switch makes contact with the end, close to the minitype travel switch, of the fault feeler lever, and a bulb structure of the other end of the fault feeler lever makes contact with a side face clamping groove of the fault sliding head sliding along a first through hole of the upper die base. The tail end of the fault correcting pin stretches out of a through hole of a stripper plate. The fault correcting pin and the guide pin are arranged in parallel, and a guide pin insertion hole and a fault correcting pin insertion hole are formed in the corresponding positions of the lower die base and a female die. The fault detection mechanism for the progressive die of the motor core has the advantages that the phenomena that waste workpieces are generated and stamping cannot be carried out normally when mis-feeding and uncompleted feeding occur in a high-speed automatic punching process of the progressive die are avoided, the service life of the progressive die is guaranteed, and the fault detection mechanism for the progressive die of the motor core is suitable for match production of various motor cores, and the quality of punched motor cores is improved.
Description
Technical field
The present invention relates to a kind of motor iron core progressive die error testing agency.
Background technology
In electromechanics trade, stator and rotor iron core is the vitals of motor, and the technical requirement of stator-rotor iron core is higher, and production lot is larger.General electric machine iron core all adopts self-feeding, the progressive die of automatic press is produced, and motor iron core progressive die is the operation punching press by each work step, and finally obtain a punching product, the distance between each work step is called step pitch.In automatic press process, the stepping accuracy between each station requires higher, and its step pitch locate mode generally adopts the automatic feeding on punch press to complete just location, and the pilot pin on progressive die makes last fine positioning, realizes its accurate spacing object.Because motor iron core progressive die drawing velocity is higher, occur as material is misdelivered, sent not in place, lamination, material arch camber, the thickness of material or width to and have error unavoidably in punching course, product does not eject or the fault such as whereabouts, thus cause progressive die cisco unity malfunction, even cause the damage of mould or punch press.
Summary of the invention
The present invention is directed to current motor iron core progressive die occurs as material is misdelivered, sent not in place, lamination, material arch camber, the thickness of material or width to and have error in automatic, high speed stamping process; product does not eject or the problem such as whereabouts; propose a kind of mistake of punch and die that prevents to rush, protect progressive die and the motor iron core progressive die error testing agency preventing from producing waste product in enormous quantities.
Motor iron core progressive die error testing agency of the present invention, it is characterized in that: comprise micro limit switch, the feeler lever of slipping up be connected with machine tool controller, foxy, pilot pin of slipping up of slipping up, described micro limit switch is fixed on to be furnished with on the upper bolster of guide finger; The trigger end of described micro limit switch contacts with the side draw-in groove of the error slippery fellow slided along upper bolster first through hole with the end thereof contacts of close micro limit switch of error feeler lever, the ball head structure of the described error feeler lever other end; The upper surface of described error slippery fellow fill on first of the first through hole top by the first stage clip and plug separate, the lower surface of described error slippery fellow is connected with the top of pilot pin of slipping up, the lower end of pilot pin of slipping up run through successively be pre-installed in cope match-plate pattern lower surface upper padding plate, punch retainer, unload solid plate and stripper, and the end of described error pilot pin stretches out from the through hole of described stripper; Described error pilot pin and pilot pin be arranged in parallel, and are respectively equipped with the pilot pin jack for inserting error pilot pin and pilot pin, pilot pin jack of slipping up at the correspondence position of die shoe and die.
Described upper bolster is provided with the first through hole for inserting error pilot pin, for inserting the second through hole of pilot pin, and the first described through hole and the second described through hole top are furnished with the first plug screw and the second plug screw respectively; The second stage clip is accompanied between the top of described pilot pin and the second described plug screw.
The end of described pilot pin and described error pilot pin is arranged on respectively by pilot pin axle sleeve and pilot pin axle sleeve of slip up and described unloads Gu Banshang, and the lower surface horizontal level of pilot pin is higher than the horizontal level of the lower surface of pilot pin of slipping up.
Described pilot pin and described error pilot pin all with the axis parallel of upper bolster.
Be positioned on punch retainer and the pilot pin unloading solid plate intermediate space and be furnished with the first packing ring.
The top of described error pilot pin is furnished with the second packing ring.
The trigger end of described micro limit switch comprises hexagonal (hexagon)nut and the 3rd stage clip, one end of the 3rd described stage clip is connected near one end of micro limit switch with described error feeler lever, the other end of the 3rd stage clip is connected with the little head end of the hexagonal (hexagon)nut inserting upper bolster third through-hole, and the stub end diameter of wherein said hexagonal (hexagon)nut is greater than the diameter of third through-hole.
Described error feeler lever is vertical with the axis of upper bolster.
Operation principle is: motor iron core progressive die is in automatic press process, if punching billot step pitch in conveying step pitch process is correct, pilot pin on progressive die and error pilot pin correctly can import the corresponding pilot pin jack of punching billot, in error pilot pin jack, if punching billot is when carrying in step pitch process the misdelivery situation that occurs (namely carrying the situation that step pitch is not in place), because the length dimension of pilot pin of slipping up is longer than other pilot pin length, error pilot pin just can not enter in corresponding error pilot pin jack, but touch above billot, at this moment pilot pin of slipping up just up moves in upper bolster, simultaneous failure slippery fellow also and then up moves, force the error feeler lever contacted with foxy central spherical of slipping up just toward moving right, touching makes the micro limit switch be fixed on upper bolster send signal, make punch press emergency brake, the punch be now fixed in upper bolster still enters die in end, thus prevent punching by mistake, protect progressive die, also prevent from producing a large amount of waste product simultaneously.
The invention has the beneficial effects as follows: error testing agency is set on the position of the suitable correcting pin-and-hole of motor iron core progressive die patrix, if can solve progressive die occur to misdeliver in High-Speed Automatic punching course material and feeding is not in place time produce punching waste product product and can not the phenomenon of normal ram, effectively guarantee carrying out smoothly of the life-span that progressive die uses and press work, be suitable for the needs of the production in enormous quantities of all kinds of electric machine iron core, improve the technical quality of punching electric machine iron core.
