Abstract
The utility model relates to a die for motor silicon sheet production, in particular to a die for motor silicon sheet production and capable of performing cutting and punching simultaneously. The die comprises a die main body and is characterized in that the die main body is provided with a threading hole bulge which is oviform or polygonal. The die can be mounted on a press capable of performing cutting and punching simultaneously, so that large-scale silicon sheet can be produced on a small-sized press, the cost is lower, and the manufacturing is easy.
Description
Technical field
The utility model relates to the mould of producing dynamo sheet, specifically relates to the dynamo sheet mould of cutting edge and dash in a kind of limit.
Background technology
Dynamo sheet is a circular configuration, have around circular a plurality of around through wires hole, making such silicon steel sheet just needs mould that the convexity of correspondence is arranged; In the prior art, it is one-time formed making such silicon steel sheet, and just its mould is circular; It is protruding to have a plurality of moulding around the mould, and according to such design, the silicon steel sheet of making big model just needs bigger mould; Require the model of press also very big, thereby make production cost higher.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, provides a kind of and can on small-sized press, produce the dynamo sheet mould that large-scale silicon steel sheet, cost limit side cut lower, easy to manufacture dash.
The technical scheme of the utility model is achieved in that the dynamo sheet mould of cutting edge and dash in the limit, comprises die ontology, and it is characterized in that: described die ontology has a through wires hole convexity.
Say that further described through wires hole convexity is avette or polygonal.
The beneficial effect of the utility model is: such dynamo sheet mould is installed in the limit and cuts edge to have on the press dash and can on small-sized press, produce large-scale silicon steel sheet, cost advantage lower, easy to manufacture.
Description of drawings
Fig. 1 is the cut edge structural representation of the dynamo sheet mould dash of the utility model limit.
Wherein, 1, die ontology 2, through wires hole convexity.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 1; The dynamo sheet mould of cutting edge and dash in the limit comprises die ontology, it is characterized in that: described die ontology 1 has a through wires hole protruding 2.
Say that further described through wires hole protruding 1 is avette or polygonal.
Such mould is installed in the limit and cuts edge on the press dash, can be processed into a silicon steel sheet through punching press repeatedly, has the effect of the utility model.
Claims (2)
1. the limit dynamo sheet mould of cutting edge and to dash comprises die ontology, and it is characterized in that: described die ontology has a through wires hole convexity.
2. mould according to claim 1 is characterized in that: described through wires hole convexity is avette or polygonal.
