Abstract
The invention provides a stator sheet of a stepping motor, and a manufacture method of a stator sheet, and belongs to the technical field of a motor, for solving the problem of high processing cost of a conventional stator sheet. The stator sheet of the stepping motor comprises a stator sheet body. The stator sheet body is provided with a plurality of yoke portions for winding coils, each yoke portion is provided with a stamping groove, the stamping grooves are disposed at the same sides of the yoke portions, and circles formed by the stamping grooves are coaxially arranged with the stator sheet body. The manufacture method of the stator sheet of the stepping motor comprises the following steps: stamping to form a rotor sheet on a silicon steel sheet; stamping to form the stator sheet on the residual silicon steel sheet; when the stator sheet is formed, after a stamping extension technology is employed, performing restamping on the yoke portions of the stator sheet to enable the yoke portions to extend inwards by 0.1 mm along the radial direction of the stator sheet body so as to achieve an enough grinding balance of the inner circle of the stator sheet; and taking out the stamping-formed stator sheet. According to the invention, the manufacture cost of the motor can be effectively reduced, and the absolute circularity of the inner hole of the stator sheet can also be ensured.
Description
Technical field
The invention belongs to technical field of motors, relate to a kind of manufacture method of stator piece and stator piece of stepping motor.
Background technology
Society in global resources scarcity, people strengthen day by day to energy-conservation consciousness, country is also advocating energy-saving and emission-reduction energetically, be widely used in the stepping motor in the fields such as industry, agricultural, business, building industry and traffic, the airtight gap of its stator and rotor is between diameter 0.1-0.15mm, be monolateral gap between 0.05-0.075mm, stator and rotor, when punching moulding, cannot guarantee stator piece endoporus and the absolute circularity of rotor sheet external diameter.If ensure stator piece internal grinding surplus, the cylindricalo grinding surplus after rotor punching is inadequate, and the mid portion that silicon steel sheet rushes after stator piece is so wasted, then uses new material stamping rotor sheet, cause stepping motor manufacturing cost significantly to increase, can not meet energy-conservation requirement.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, proposed the stator piece of a kind of reasonable in design, stepping motor easy to process.
A kind of manufacture method of saving material, stator piece easy to process has also been proposed.
Object of the present invention can realize by following technical proposal:
A kind of stator piece of stepping motor, comprise rounded stator lamellar body, the middle part of described stator lamellar body is hollow structure, it is characterized in that, on described stator lamellar body, there are some yokes for coiling that extend radially inwardly along stator lamellar body, on yoke described in each, be equipped with stamped groove, described stamped groove is positioned at the homonymy of yoke and the circle consisting of stamped groove and stator lamellar body and coaxially arranges.
In the stator piece of above-mentioned stepping motor, described yoke evenly arranges.
In the stator piece of above-mentioned stepping motor, described yoke is 12.
In the stator piece of above-mentioned stepping motor, the outer ring of described stator lamellar body is provided with the location hole for locating.
A manufacture method for step motor stator sheet, comprises the following steps:
(1) calculate punch forming rotor sheet on the silicon steel sheet of blank dimension, during punching press, guaranteeing the cylindricalo grinding surplus of rotor sheet;
(2) punch forming stator piece on remaining silicon steel sheet;
(3) after stator piece moulding, adopt after punching press elongation technology, punching press again on the yoke of stator piece, makes yoke extend radially inwardly 0.1mm along stator lamellar body, to reach enough grinding allowances of stator piece inner circle mill;
(4) stamping forming stator piece is taken out.
Take full advantage of silicon steel sheet, two times punch on stator piece, makes yoke extend radially inwardly 0.1mm along stator lamellar body, and yoke is along the stator piece diameter 0.2mm that extends internally, make stator piece inner circle grinding tool have enough grinding allowances, effectively reduced the manufacturing cost of stepping motor.
The stator piece of this stepping motor and the manufacture method of stator piece have the following advantages: both moulding rotor sheet on same silicon steel sheet, moulding stator piece again, guarantee the cylindricalo grinding surplus of rotor sheet and the internal grinding surplus of stator piece simultaneously, make full use of silicon steel sheet, effectively reduce the manufacturing cost of stepping motor.The stator piece processing in this way, the absolute circularity of its endoporus is easy to assurance, and the airtight gap between the stator after moulding and rotor is easy to guarantee, the operating efficiency of raising motor, processing cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment provided by the invention.
Fig. 2 is the cutaway view of Fig. 1 provided by the invention.
In figure, 1, stator lamellar body; 2, yoke; 21, stamped groove; 3, location hole.
Embodiment
Be below specific embodiments of the invention by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
The stator piece of stepping motor as shown in Figure 1, comprise rounded stator lamellar body 1, the middle part of stator lamellar body 1 is hollow structure, as shown in Figure 1, the yoke 2 for coiling extending radially inwardly along stator lamellar body 1 on stator lamellar body 1 with some even settings, on each yoke 2, be equipped with stamped groove 21, as depicted in figs. 1 and 2, stamped groove 21 is positioned at the homonymy of yoke 2 and the circle consisting of stamped groove 21 and stator lamellar body 1 and coaxially arranges.In the present embodiment, as shown in Figure 1, yoke 2 is 12, is provided with the location hole 3 for locating in the outer ring of stator lamellar body 1.
Step motor stator sheet as shown in Figure 1 can be manufactured by the following method, and concrete steps are as follows: (1) is calculating punch forming rotor sheet on the silicon steel sheet of blank dimension, guarantees the cylindricalo grinding surplus of rotor sheet during punching press; (2) punch forming stator piece on remaining silicon steel sheet; (3) after stator piece moulding, adopt after punching press elongation technology, punching press again on the yoke 2 of stator piece, makes yoke 2 extend radially inwardly 0.1mm along stator lamellar body 1, to reach enough grinding allowances of stator piece inner circle mill; (4) stamping forming stator piece is taken out.
Concrete, punch forming stator piece on remaining silicon steel sheet, now the internal diameter of yoke 2 is 70mm, after stator piece moulding, adopt after punching press elongation technology, punching press again on the yoke 2 of stator piece, makes yoke 2 extend radially inwardly 0.1mm along stator lamellar body 1, to reach enough grinding allowances of stator piece inner circle mill, now the internal diameter of yoke 2 is 69.8mm.
