Abstract
The invention relates to a method for manufacturing laminated rotor and stator. In the method, strip steel is used as a raw material, and is punched and riveted by adopting a punch and a punch molding and rivet mould arranged on the punch to manufacture the stator and rotor; a lower mould of the punch molding and rivet mould is provided with a rivet bin; the rivet bin is provided with a rotating device; the punch is provided with a controller and a slide real-time position state inductor; the slide real-time position state inductor and the rotating device are connected with the controller; the controller indicates the rotating device to rotate at an angle alpha before the next stator and rotor is contacted with last stator and rotor in the rivet bin, so that the rotating device can deflect between two laminated adjacent stator and rotor. By combining high-speed automatic production line implementation of motor stator and rotor punching, the product accuracy can be greatly improved, the materials can be saved, the consumption is reduced, and the social benefit is remarkable.
Description
Technical field
The present invention relates to a kind of manufacturing laminated rotor and stator, especially have the manufacturing laminated rotor and stator of skewed slot or V groove.
Background technology
Be to reduce harmonic wave, thus noise and vibration when reducing motor rotation.Many motor stator and rotor adopt stacked structure.For further improving radiating effect that stator and rotor are in operation, alleviating complete machine weight, on stator and rotor, be provided with the groove line of some.Along with development of technology, the form of motor increases, and in order to improve the efficiency of motor better, the designer improves the structure of above-mentioned groove line, as is set to oblique or V-arrangement, makes the more requirement of aerodynamic of dispelling the heat when motor rotation.Shown in Fig. 3,4, be respectively skewed slot shape rotor, V flute profile rotor.
In the prior art, what the processing of this type of rotor was taked is that machinery adds artificial way, at first is to process the stator and rotor sheet, manually superimposed then, controls adjacent stator and rotor sheet deflection certain angle when superimposed, the final rotor with skewed slot shape or V flute profile that forms.It is that the Chinese patent of ZL200720113415.5 discloses a kind of frock that can improve man efficiency that name is called " rotor chute closed assembly instrument ", the patent No., and it can make the rotor of closed assembly form uniform skewed slot.But still exist working (machining) efficiency low, the defective that labour intensity is big.In addition, processing stator and rotor sheet generally adopts the band steel, and ordinary band steel is owing to exist monolateral thickness error, the problem of rotor global existence deviation from cylindrical form when making closed assembly.
Summary of the invention
The present invention is directed to the problems of the prior art, provide a kind of punching molding, stacked riveted, skewed slot moulding to carry out automatically synchronously, and the high manufacturing laminated rotor and stator of finished form precision.
Technical scheme of the present invention is: with the band steel is raw material, adopt punch press, the punching molding riveting die that is installed on the punch press is die-cut piecewise, riveted is made rotor, the counterdie of described punching molding riveting die is provided with the riveted storehouse, the riveted storehouse is provided with tumbler, described punch press is provided with controller and slide block real time position state sensor, slide block real time position state sensor is connected controller with tumbler, described controller instruction tumbler a slice rotor sheet contact down be positioned at the riveted storehouse on rotate an angle [alpha] before a slice rotor sheet, make deflection between stacked adjacent two rotor sheets.
The amount of spin of described tumbler is α+90 or 180 °.
The present invention utilizes controller instruction counterdie to rotate, and after rotor sheet one that upper punch scales off fell into counterdie riveted storehouse, patrix was with the slide block return; At this moment, counterdie turns an angle and waits for a slice rotor sheet down; Patrix with rotor sheet two is die-cut get off after again with rotor sheet two riveteds to rotor sheet one; Because rotor sheet one rotated certain angle, make rotor sheet two with respect to rotor sheet one certain angle that staggered.Stacked reaching when a certain amount of, some rotor sheets with notch form cylindrical shapes, and the notch at its edge then forms skewed slot or V-shaped groove.Because the problem of the monolateral thickness error of raw band steel ubiquity, the error of a slice is a lot, and the error of multi-disc is just very big, and shown in Fig. 5,6, if this is not controlled, the cylindricity of rotor finished product just can not get ensureing.The present invention is a head it off, has taked the method for " deflection add transfer the limit ", promptly increases by 90 ° or 180 degree on the deflection angle basis, and the rotor sheet with thickness error has guaranteed the whole form accuracy in stack back after transferring the limit.The present invention implements in conjunction with electric machine rotor punching press high-speed automated line, can improve product precision, materials saving, obvious social benefit greatly.

Embodiment
The present invention such as Fig. 1, shown in 2, with the band steel is raw material 7, adopt punch press 1, the punching molding riveting die that is installed on the punch press 1 is die-cut piecewise, riveted is made rotor, the counterdie 5 of punching molding riveting die is provided with riveted storehouse 4, riveted storehouse 4 is provided with tumbler 2, punch press 1 is provided with controller 3 and slide block real time position state sensor, slide block real time position state sensor is connected controller 3 with tumbler 2, controller 3 instruction tumblers 2 a slice rotor sheet 6 contacts down be positioned at riveted storehouse 4 on rotation one angle [alpha] before a slice rotor sheet 6, make deflection between stacked adjacent two rotor sheets 6.
For overcoming the problem of band steel 7 thickness errors, it is α+90 or 180 ° that tumbler 2 drives the amount of spin that rotates in the riveted storehouses.
Punch press is a main control system with the high-speed fine press, is equipped with Japanese Mitsubishi Programmable Logic Controller, and Japanese east stepper motor driver and east stepping motor and rotor mold system are formed.The function of this equipment realizes by the co-ordination of these three parts.The automatically controlled core of high-speed fine press controller adopts PLC, emission high impulse data when lathe each run to 210 is spent, the high impulse transfer of data is finished to stepper motor driver and is handled and the drive stepping motor rotation, drive tumbler work then, thereby obtain needed angle technological requirement.
