Abstract
The utility model discloses a stator punching sheet of a chain-type motor. The punching sheet comprises yoke parts (1), teeth parts (2) and trunkings (3) between the teeth parts (2). The punching sheet is slender-strip-shaped, fold grooves (4) are formed in the trunckings (3) towards the yoke parts (1), a shrink hole (5) is formed at the top of each fold groove (4), and the punching sheet can be bent towards the trunkings (3) around the shrink holes (5) to achieve end-to-end connection. The stator punching sheet saves materials at one hand, is easiness in winding at the other hand, improves both the utilization ratio of materials and the production efficiency, simultaneously increases the copper space factor of the motor and improves the motor property.
Description
Technical field
The utility model relates to electric motors, especially the stator punching of motor.
Background technology
The conventional motors stator punching all is once-forming when punching press; stator core is by the riveting moulding that superposes; synthetic stator core; its stator winding speed is slow, inefficiency; material use is low, motor cost height, and also the motor copper factor is low; influence motor performance, be unfavorable for the production of extensiveization.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of economical with materials and makes things convenient for coil winding, motor stator punching that copper factor is high again.
For achieving the above object, the utility model provides the punching of a kind of chain type motor stator, comprise the wire casing 3 between yoke portion 1, tooth portion 2, the tooth portion 2, described punching is an elongated strip shaped, wire casing 3 is shaped on to yoke portion 1 and closes up groove 4, be shaped on shrinkage cavity 5 on the top that closes up groove 4, described punching can be bent to end to end to wire casing 3 directions around shrinkage cavity 5.
When described punching is bent to two ends when relative, two limits that close up groove 4 close up to closely connected mutually.
When described punching is bent to two ends when relative, the connecting part welding.
The utility model has been saved material on the one hand, is convenient on the other hand wind the line before welding, improves stock utilization and enhances productivity, and can increase the copper factor of motor simultaneously, improves motor performance.
Description of drawings
Fig. 1 is the chain type motor stator punching of elongated stripe shape;
Fig. 2 is the chain type motor stator punching that bends moulding;
Fig. 3 is the punching out The layout of the chain type motor stator punching of elongated stripe shape.
Among the figure: 1, yoke portion, 2, tooth portion, 3, wire casing, 4, close up groove, 5, shrinkage cavity, 6, projection, 7, groove.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, 2, the utility model is that the punching upper punch at elongated stripe shape is shaped on wire casing 3, thereby form yoke portion 1 and tooth portion 2, close up groove 4 from wire casing 3 to 1 punching out of yoke portion, closing up the top punching out shrinkage cavity 5 of groove 4, yoke portion 1 at an end of punching establishes projection 6, establish groove 7 at its other end, when the punching of elongated strip shaped type end to end to the bending of wire casing direction until the yoke portion 1 at two ends, weld with argon arc welding the connecting part, projection 6 is embedded in the groove 7, and two limits that close up groove 4 close up to closely connected mutually around shrinkage cavity 5.
Make punch die with reference to Fig. 1, the tooth portion of a leptosomatic punching stretches into the wire casing of another punching, thereby goes out punching (as shown in Figure 3) in couples, tooth portion 2 space certain distances.Save material on the one hand, be convenient on the other hand before welding, wind the line, improved stock utilization and enhance productivity, can increase the copper factor of motor simultaneously, improved motor performance.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
Claims (4)
