[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a split generator rotor punching sheet, which has the following beneficial effects:

[0014] In the split-type generator rotor punching, after the first punching and the second punching are positioned, when the second punching is in the process of descending, the positioning block will be inserted into the positioning groove, so that the first punching and the second punching can be easily spliced. In this structure, the initial state of the first punching and the second punching is a split structure. If a part of the first punching or the second punching is damaged, only the first punching or the second punching only needs to be replaced, thereby avoiding waste of resources.

[0015] During the use of the first punching sheet and the second punching sheet, the design of the punching sheet is optimized by providing the first heat dissipation groove and the second heat dissipation groove, and the heat dissipation groove is opened to increase the heat dissipation surface area to enhance the heat dissipation effect of the first punching sheet and the second punching sheet.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model discloses a split generator rotor punching sheet, comprising a first punching sheet 1 and a second punching sheet 2, two positioning grooves 4 are symmetrically arranged at both ends of the first punching sheet 1, two positioning blocks 5 inserted into the positioning grooves 4 are symmetrically arranged at both ends of the second punching sheet 2, a plurality of positioning holes 3 are arranged on the first punching sheet 1 and the second punching sheet 2, a plurality of first heat dissipation grooves 7 are arranged on the outer walls of the first punching sheet 1 and the second punching sheet 2, a plurality of second heat dissipation grooves 8 are arranged on the inner walls of the first heat dissipation grooves 7, a plurality of vertical rods penetrating the positioning holes 3 are arranged on a designated workbench, so that The first punching sheet 1 and the second punching sheet 2 are convenient to position. When the second punching sheet 2 is in the process of descending, the positioning block 5 will be inserted into the positioning groove 4, so that the first punching sheet 1 and the second punching sheet 2 can be conveniently spliced. After the plurality of first punching sheets 1 and the second punching sheets 2 are spliced, the first punching sheet 1 and the second punching sheet 2 can be glued. In this structure, the initial state of the first punching sheet 1 and the second punching sheet 2 is a split structure. If a part of the first punching sheet 1 or the second punching sheet 2 is damaged, only the first punching sheet 1 or the second punching sheet 2 needs to be replaced, so as to avoid waste of resources.
