Abstract

The invention discloses a method for processing a chute of an iron core of a motor stator. Each stamped steel is of the same structure; a plurality of sector stamped steels are spliced into laminations, wherein each single layer of lamination is of a peripheral structure; when the stamped steels on each layer are laminated, each layer of lamination rotates by a preset rotating angle relative to a previous layer of lamination, so that the iron core formed by lamination has a chute structure; and due to the setting of the rotating angle, joints between the sector stamped steels on each layer can be staggered, the integral structure is more reasonable, marking on each layer of sector stamped sheets does not need to be considered in the laminating process, the production and machining process is relatively more convenient and simpler, and the working efficiency is improved.

Description

A kind of processing method of motor stator core skewed slot

Technical field

The present invention relates to stator core construction for motor, be specially the processing method of large skewed stator core slot.

Background technology

Be directed to large stator core, its external diameter is greater than the iron core of 1000mm, generally adopts segmental punching, and a plurality of segmental punchings form circumference, and iron core forms flume structure by the punching of individual layer circumference through laminating.Adopting at present the processing method that forms in this way iron core chute is from second layer segmental punching, in the groove radial centre lines of every layer of segmental punching, with respect to the segmental punching groove radial centre lines of one deck above, depart from an angle, wherein every layer of segmental punching is all to carry out mark, in segmental punching punching press, complete and just carry out at that time mark, be marked as the 1st layer to N layer, then according to flag sequence, laminate formation iron core chute when every stacked pressure, can not confound order, otherwise can cause laminating angle generation mistake, cannot form iron core chute.Every layer of segmental punching carries out laminating after mark so again, and the segmental punching of every layer is not that standard universal can laminate, and has caused in process of production inconvenience very, and such processing method is more numerous and diverse, has reduced operating efficiency.

Summary of the invention

For the defect existing in prior art, the object of the present invention is to provide a kind of processing method of motor stator core skewed slot, segmental punching is standard universal structure, the segmental punching that each layer laminates is all same structure, no longer carry out the mark of each layer, and the segmental punching place of interconnecting is more tight, the course of processing is more convenient simple, has improved operating efficiency.

Above-mentioned purpose is achieved through the following technical solutions:

A processing method for motor stator core skewed slot, adopts following procedure of processing:

1. feeding, punch forming: get billot, by pressing equipment, form segmental punching;

2. splicing: every layer of lamination that is spliced into circle configurations by multi-disc segmental punching;

3. laminate: the 2nd layer of beginning, even level is (30+(n-1) * A/N with respect to the anglec of rotation of last layer) °, odd-level is ((n-1) * A/N) ° with respect to the anglec of rotation of last layer, wherein n is the number of plies, and n >=2, N is total number of plies, A is angle of bevel;

4. integer: the stator core that laminates moulding forms the integrative-structure of solidating by mould.

Described segmental punching punching press forms the splicing connecting portion that surface has slot for winding and two ends, wherein one end punching press forms draw-in groove, other end punching press forms and connects projection, multi-disc segmental punching is snapped in another segmental punching one end draw-in groove and is formed circumference lamination by connection projection, and it is more tight that the cooperation of projection and draw-in groove is connected segmental punching.

Described individual layer lamination splices and combines formation by six segmental punchings.

The segmental punching that utilizes above-mentioned technique to manufacture, every punching is all identical structure, multi-disc segmental punching is spliced into the lamination of individual layer circle configurations, every layer when mutually laminating, lamination all rotates a predetermined anglec of rotation with respect to last layer lamination, makes the iron core that laminates moulding have flume structure.The setting of the anglec of rotation simultaneously can be so that stagger mutually in the junction between segmental punching on every layer, overall structure is more reasonable, in lamination process, need not consider the mark of every layer of segmental punching, it is convenient simple comparatively speaking that process of manufacture becomes, and improved operating efficiency again.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Fig. 1-9, a kind of processing method of motor stator core skewed slot, adopt following procedure of processing: first, get billot, by pressing equipment, form segmental punching 1, segmental punching 1 punching press forms the splicing connecting portion that surface has slot for winding 11 and two ends, one end punching press of segmental punching forms draw-in groove 12, other end punching press forms and connects projection 13, multi-disc segmental punching 1 snaps in by connecting projection 13 lamination 2 that is spliced to form circle configurations in another segmental punching one end draw-in groove 12, and the cooperation of projection 13 and draw-in groove 12 makes the connection between segmental punching 1 more tight.As shown in Fig. 1-6, the segmental punching of the 1st layer is spliced to form the lamination of circle configurations, since the 2nd layer, the lamination of the 2nd layer laminates after being rotated with respect to the 1st laminates, rotation be take lamination radial centre lines as benchmark, and the anglec of rotation is (30+(n-1) * A/N) °, the 2nd layer of rotating photo rotated 30.1 ° for the 1st layer, the 3rd layer of anglec of rotation with respect to the 2nd layer equals to have rotated 0.2 ° for ((n-1) * A/N) °, and the 4th layer has been rotated 30.3 ° with respect to the 3rd layer.That is to say, since the 2nd layer, even level is (30+(n-1) * A/N with respect to the anglec of rotation of last layer) °, odd-level is ((n-1) * A/N) ° with respect to the anglec of rotation of last layer, middle n is the number of plies, and n >=2, N is total number of plies, A is angle of bevel.In the present embodiment, every layer of lamination 2 that adopts six segmental punchings 1 to be spliced to form circle configurations, wherein angle of bevel A is 5 degree, interlaced the laminating in splicing junction on every laminates, does not have impact to overall structure.Finally, the stator core 3 laminating into after predetermined number of layers is formed with skewed slot 31 structures, then by mould, forms the integrative-structure of solidating.

The segmental punching that utilizes above-mentioned technique to manufacture, every punching is all identical structure, multi-disc segmental punching 1 is spliced into the lamination 2 of individual layer circle configurations, every layer when mutually laminating, lamination all rotates a predetermined anglec of rotation with respect to last layer lamination, make the iron core 3 that laminates moulding there is flume structure 31, as Figure 7-9.The setting of the anglec of rotation simultaneously can be so that stagger mutually in the junction between segmental punching on every layer, overall structure is more reasonable, in lamination process, need not consider the mark of every layer of segmental punching, it is convenient simple comparatively speaking that process of manufacture becomes, and improved operating efficiency again.
