Abstract

The utility model relates to a rotatable component on a motor magnetic circuit, especially to a casting aluminium rotor punching sheet, which includes a sheet body, a rotating shaft aperture, a keyway and a guide groove arranged on the radial face of the sheet body and is characterized in that slits for communicating the guide grooves are cut from the outer groove edge of the guide groove to the radial face on the circumference of the sheet body; a deformation stress which is produced in punching the guide groove by the punching sheet is completely released so as to achieve a flat punching sheet. The utility model solves the problem that the ventilation groove is curved when the punching sheets are laminated and utilizes the rotor punching sheet with such structure to achieve a good technical effect of designing groove type in opening and casting in closing. The utility model has the simple structure, low cost, reasonable technology, high production efficiency and good practicability.

Description

A kind of cast-aluminum rotor punching

Technical field

The utility model relates to the rotational components of motor magnetic circuit, the cast-aluminum rotor punching of radial ventilation groove bending when referring in particular to and a kind ofly eliminating punching stress, improving punching and laminate.

Background technology

We know, some rotor punchings are laminated the back fix with rotating shaft, irritate aluminium and make cast-aluminum motor rotor.In order to make the air can directly cooled machine inner core part, the ventilation slot of a band radial ventilation ditch be set between rotor punching at a certain distance, and forms radial ventilation system.At present, the used punching of cast-aluminum rotor includes lamellar body, shaft hole, keyway and is opened in sliver groove on the lamellar body sagittal plane.The grooved of its sliver groove has two kinds of the grooved of remaining silent and opening grooveds.The employing rotor that the punching of grooved sliver groove is made of remaining silent, though its casting technique guarantees well, but its punching can produce distortional stress when the punching out flute profile, after some punching stacks, this distortional stress can obtain amplification and cause the ventilation slot bending, when turning round, the rotor of ventilation slot bending can produce axial endplay power, the useful life of reducing motor greatly owing to wind direction fluctuates.And the rotor that the punching of adopting opening grooved sliver groove is made, the open slot in its punching can be eliminated punching stress and reach the smooth purpose of punching.But the notch that is difficult to during the casting aluminum rotor of opening grooved to guarantee to ventilate is scurried the phenomenon of aluminium, and its technology difficulty is big, the percent defective height.

Summary of the invention

Scurry the deficiency of aluminium in order to solve the notch that is difficult to when there is the casting aluminum rotor that ventilation channel plate bending, opening grooved punching make in rotor that the grooved punching of remaining silent in the prior art makes to avoid to ventilate, the utility model provides a kind of simple in structure, cost is low, technology is reasonable, practical cast-aluminum rotor punching.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of cast-aluminum rotor punching, it comprises lamellar body, shaft hole, keyway and is opened in sliver groove on the lamellar body sagittal plane, it is characterized in that: in the cutting to the sagittal plane of lamellar body periphery of the outer trough edge of sliver groove the crack of cutting that is communicated with the sliver groove is arranged.

The described sliver groove that is opened on the lamellar body sagittal plane, its outer trough edge to the sagittal plane distance of lamellar body periphery is 0.2mm-0.4mm.

The utility model is because the cutting to the sagittal plane of lamellar body periphery of the outer trough edge of sliver groove has the crack of cutting that is communicated with the sliver groove, and the distortional stress that punching is produced when punching out sliver groove is cut the place, crack at this and discharged fully, and obtains smooth punching.This is cut the crack and compares with open slot, and its gap is little, during casting aluminum rotor, can not produce and scurry the aluminium phenomenon.Therefore, the good process effect of utilizing the rotor punching of this structure to reach the open design grooved, remaining silent and cast.

The utility model is simple in structure, and cost is low, and technology is reasonable, and the production efficiency height is practical.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a kind of structural front view of the present utility model.

Fig. 2 is the schematic diagram that the utility model adds man-hour.

1. lamellar bodies among the figure, 2. shaft hole, 3. keyway, 4. the sliver groove is 5. radially reserved face, 6. cuts the crack, 7. punch die, 8. cutting knife.

Embodiment

As shown in Figure 1, a kind of cast-aluminum rotor punching, it includes lamellar body 1, and this lamellar body 1 adopts silicon steel sheet or silicon steel sheet material.

In Fig. 1, shaft hole 2 punching out are in the center of lamellar body 1, and stamping-out has keyway 3 on the lamellar body outside the rotating shaft hole circle, this shaft hole 2 and keyway 3 punching out simultaneously.

At the sliver groove 4 that the sagittal plane punching out of lamellar body has, the outer trough edge of this sliver groove 4 leaves the reservation face 5 of 0.3mm to the sagittal plane of lamellar body periphery.This radially reserve cutting on the face 5 have be communicated with the sliver groove cut crack 6.

As shown in Figure 2, adopt this rotor punching of notching press stamping-out of one-shot mould, be provided with punch die 7 and cutting knife 8 side by side simultaneously on this jet-bedding scouring machine, its job step is as follows:

1, adjustment equipment meets the sliver groove and counts parameter, the preparation when carrying out the punching jet-bedding;

2, punching is installed, the operation notching press, punching is to anticlockwise, and by the punch die 7 punching out first sliver groove, cutting knife 8 will cut the crack of cutting of a segment length at the left end sagittal plane of this sliver groove to the punching periphery simultaneously;

3, punching continues to carry out jet-bedding second time to anticlockwise, the punch die 7 punching out second sliver groove, and cutting knife 8 is with the radially reservation face cut-out to the lamellar body periphery of the outer trough edge of the first sliver groove simultaneously;

4, by that analogy, when punching rotated a circle, in punch die 7 punching out sliver grooves, the outer trough edge of all sliver grooves to the radially reservation face of lamellar body periphery was cut off successively by cutting knife 7.Full wafer stress is all eliminated, the smooth no buckling phenomenon of punching, and it is little that it cuts the gap, crack, and the notch of sliver groove still is a closed state.

The utility model is applied to the cast-aluminum rotor with the radial ventilation groove, and it has been eliminated punching stress, has improved the phenomenon of ventilation slot bending when punching laminates, the axial endplay that produces when reducing motor rotation, the serviceability and the life-span of improving motor greatly.
