Abstract

The utility model motor case steel plate, comprising: steel plate body, and the both sides of described steel plate body are respectively equipped with the first convex hasp and the second convex hasp; Projection and groove is also respectively equipped with in the both sides of described steel plate body; Wherein said projection and described first convex hasp homonymy are arranged, between described first convex hasp; Described groove and described second convex hasp homonymy arrange, are positioned on described second convex hasp; Described projection is corresponding with described groove.The quantity of described projection and described groove is multiple.The utility model motor case steel plate increases protruding and described groove on the basis of former hasp structure, to increase the contact length of the first convex hasp and the second convex hasp, the part that the contact length supplementing the first convex hasp and the second convex hasp caused because material elongation is less than normal reduces, improves the fastness of former designing requirement further.

Description

Motor case steel plate
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of motor case steel plate.
Background technology
Existing design motor case is shown in accompanying drawing 1 when steel plate state, becomes casing to see accompanying drawing 2 after roll of steel plate circle.In the course of processing, the mechanical performance of material there will be fluctuation, elongation (in the scope that material trademark specifies) bigger than normal or less than normal.Less than normal if there is elongation, be commonly called as partially hard, under the effect of the pressure, when convex hasp A1 enters recessed hasp B2, entering rear convex with recessed linear contact lay by straight more difficulty change bend cutting can reduce, and occur part point cantact, affect casing seam fastness, fastness is not inconsistent requirement.
Utility model content
The purpose of this utility model is to provide a kind of motor case steel plate improving the fastness of shell roll of steel plate circle hasp.
For solving the problems of the technologies described above, the utility model motor case steel plate, comprising: steel plate body, and the both sides of described steel plate body are respectively equipped with the first convex hasp and the second convex hasp; Projection and groove is also respectively equipped with in the both sides of described steel plate body; Wherein said projection and described first convex hasp homonymy are arranged, between described first convex hasp; Described groove and described second convex hasp homonymy arrange, are positioned on described second convex hasp; Described projection is corresponding with described groove.
Preferably, the quantity of described projection and described groove is multiple.
The utility model motor case steel plate increases protruding and described groove on the basis of former hasp structure, to increase the contact length of the first convex hasp and the second convex hasp, the part that the contact length supplementing the first convex hasp and the second convex hasp caused because material elongation is less than normal reduces, improves the fastness of former designing requirement further.
Accompanying drawing explanation
Fig. 1 is prior art steel plate structure schematic diagram one;
Fig. 2 is that prior art steel plate is rolled into casing schematic diagram;
Fig. 3 is the utility model motor case steel plate structure schematic diagram;
Fig. 4 is the convex hasp of the utility model motor case steel plate first and the second convex hasp clamping schematic diagram.
Description of reference numerals in the utility model motor case steel plate accompanying drawing:
The convex hasp of the convex hasp 3-second of 1-steel plate body 2-first
The protruding 5-groove of 4-
Embodiment
Below in conjunction with accompanying drawing, the utility model motor case steel plate is described in further detail.
As shown in Figure 3, Figure 4, the utility model motor case steel plate, comprising: the first convex hasp 2 and the second convex hasp 3 that steel plate body 1 and both sides thereof are arranged respectively.Protruding 4 are increased between first convex hasp 2, corresponding, increase groove 5 on the top of the second convex hasp 3, projection 4 is corresponding with groove 5.To increase by the first convex hasp 2 and the second convex hasp 3 contact length, overcome the fluctuation of material property, guarantee the consistency of fastness, improve the utilance of material.
The utility model motor case steel plate increases protruding and described recessed on the basis of former hasp structure
Groove, to increase the contact length of the first convex hasp and the second convex hasp, the part that the contact length supplementing the first convex hasp and the second convex hasp caused because material elongation is less than normal reduces, improves the fastness of former designing requirement further.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.

Claims (2)
