Abstract

The utility model discloses an improved structure of a stator punching sheet set, which belongs to the technical field of motor stator punching sheets. The improved structure comprises a plurality of stator punching sheets. Each stator punching sheet comprises two short sides and is provided with four roundings; four same steps are symmetrically arranged on the two short sides; stator punching sets are staggered in two lines; and two adjacent steps on the same sides of two adjacent stator punching sheets in one line are spliced with two steps on the same side of one stator punching sheet in the other line. By adopting the technical scheme, on the premise without changing the specification of the stator punching sheet, the utility model is beneficial to saving the cost when the stator is discharged, can save a great amount of raw materials for motor manufactures during production in batch and is worthy of being widely popularized.

Description

A kind of improvement structure of stator punching group

[technical field]

The utility model relates to a kind of improvement structure of stator punching group, belongs to the motor stator punching technical field.

[background technology]

Press, with reference to shown in Figure 1, stator punching 1 ' is that minor face a ' is 102.8mm, and long limit b ' is the structure that roughly is rectangle of 112mm, and four jiaos of stator punching 1 ' have rounding 2 '; As shown in Figure 2, having shown four stator punchings that punching out arranged side by side forms, is four stator punchings of punching out two row arranged side by side on the silicon strip that a width is 224mm, and these four stator punchings are sphere of movements for the elephants shape and arrange.Yet the conventional structure of this stator punching is unfavorable for that motor manufacturing enterprise saves cost when the stator punching discharge, and back road discharge operation can only be followed routine and punching out stator punching side by side.

In view of this, the stator punching of existing structure is needed improvement badly.

[utility model content]

The deficiency that the utility model exists at above-mentioned prior art and a kind of improvement structure of stator punching group is provided in the hope of under the condition that does not change the stator punching specification, is reached the manufacturing cost that reduces stator punching.

For solving the problems of the technologies described above, the utility model provides following technical scheme:

A kind of improvement structure of stator punching group, form by a plurality of stator punchings, stator punching has two long limits, two minor faces and four roundings, on two minor faces of each stator punching there be and four of four rounding transition identical steps symmetric arrangement, described stator punching group is the biserial dislocation arranges that wherein adjacent two steps of two stator punchings that row are adjacent and two steps of a stator punching homonymy of another row coincide.

The minor face of said stator punching is 102.8mm, and long limit is 112mm.

Compare with the stator punching of existing structure, the utlity model has following beneficial effect:

(minor face is 102.8mm not changing the stator punching specification, long limit is 112mm) prerequisite under, four identical steps of symmetric arrangement on two minor faces of stator punching, make when the stator punching group is biserial dislocation layout, adjacent two steps of two stator punchings that row are adjacent and two steps of a stator punching homonymy of another row coincide therein, so, by originally need be on the silicon strip that a width is 224mm the punching out two sub-punching that is ranked, become on the silicon strip that a width is 218.5mm the dislocation punching out two sub-punching that is ranked, help when the stator punching discharge, saving cost, can be motor manufacturer during batch process and save a large amount of raw material, be worth in the industry cycle wideling popularize.

[description of drawings]

Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.

Fig. 1 is a common stator punching structural representation;

Fig. 2 is the structural representation (only showing two row, four stator punchings that are sphere of movements for the elephants shape layout among the figure) of common stator punching group;

Fig. 3 is the utility model stator laminating structure schematic diagram;

Fig. 4 is the utility model stator punching group structural representation (only showing two row, four stator punchings that are the dislocation layout among the figure).

[embodiment]

Be 102.8 to be mm with minor face a now, the stator punching that long limit b is 112m describes for row:

See also shown in Figure 3ly, stator punching 1 has four roundings 2, and symmetry offers four identical steps on its two minor face a, and each step and adjacent rounding 2 transition.

See also shown in Figure 4, the stator punching group is the biserial dislocation and arranges stator punching, being positioned at above-listed two stator punchings and a following left side plays first stator punching and is the layout of falling the isosceles triangle, be positioned at following two stator punchings and then play second stator punching formation isosceles triangle general layout with an above-listed left side, (can certainly be that following two stator punchings and an above-listed left side are played first stator punching and be isosceles triangle and arrange, above-listed two stator punchings then play second stator punching with a following left side and constitute the general layout of falling the isosceles triangle), thereby make above-listed two stator punchings be positioned at the below adjacent step 10, step 12 plays the step 11 of first stator punching respectively with a following left side, step 13 coincides, near the step 14 that rise second stator punching lower right corner on an above-listed left side then coincides with near the step 15 that rise the upper left corner of second stator punching on a following left side, the two row stator punchings like this arrangement that misplaces successively, the step of two row stator punchings is dislocation coincidence successively then, has finally realized the purpose of dislocation punching out two row stator punchings (long limit still is 112mm) on the silicon strip that a width is 218.5mm.

The quantity of above-mentioned two row stator punchings is not limited, and punching out in endless succession can misplace on the silicon strip that a width is 218.5mm.
