Abstract
The utility model relates to the punching press die-cutting moulds that one kind can prevent silicon steel sheet alice injustice phenomenon, the punching press die-cutting mould is divided into four stations, first cross cutting blade of the first station is divided into four fan blades, fan-shaped region position between the position of four fan blades and the winding section of silicon steel sheet is corresponding, there is an outwardly projecting taper blade in the middle part of the outer arc of each fan blades, fracture site between taper blade edge position and the curved portion on the outside of silicon steel sheet is corresponding, and the width of the taper blade is less than the width of fracture.Using the utility model die-cutting mould, after the first cross cutting blade, the region that fan blades and taper blade are cut not fully achieved the fan-shaped region of silicon steel sheet and the size of fracture site, when last cross cutting being made to form curved portion and fracture in this way, there is material surplus in the periphery of curved portion end, curved portion generates alice or uneven phenomenon when so as to prevent from being finally punched, and keeps silicon steel sheet surface smoothness higher.
Description
Technical field:
The utility model relates to silicon steel sheet production mould equipment technical fields, and refering in particular to one kind can prevent silicon steel sheet alice uneven
The punching press die-cutting mould of phenomenon.
Background technique:
Silicon steel sheet is the important part for producing machine winding, and according to different motor needs, the shape of silicon steel sheet is also different.
In a kind of micro-machine, as shown in Figure 1, silicon steel sheet has a central circular and is uniformly arranged on central circular periphery
Four winding sections, each winding section are equipped with a rectangular opening, and the outer end of winding section is equipped with arc-shaped curved portion, adjacent curved portion
Between have a fracture.In the prior art, the first step of punching press die-cutting mould is at punching between the winding section of silicon steel sheet
Four fan-shaped regions, and the size of fan-shaped region and incision position and the size of final silicon steel flake products are completely the same；That is silicon
The i.e. molding completely after first step of the size of the curved portion inboard portion of steel disc；And in the outside of finally punching curved portion
When, since inside dimensions are molded, the inboard portion of curved portion does not stress, only exterior portion meeting stress, thus holds
So that the curved portion of silicon steel sheet is generated alice phenomenon, causes flatness after silicon steel sheetmolding poor, influence lamination and final winding
Quality.
Utility model content:
The purpose of the utility model is to overcome the above-mentioned shortcomings of existing equipment, and silicon steel sheet alice can be prevented by providing one kind
The punching press die-cutting mould of uneven phenomenon.
The technical solution adopted in the utility model is: one kind can prevent the punching press of silicon steel sheet alice injustice phenomenon to be die cut mould
Tool, silicon steel sheet have a central circular and are uniformly arranged on four winding sections of central circular periphery, and each winding section is set
There is a rectangular opening, the outer end of winding section is equipped with arc-shaped curved portion, has a fracture between adjacent curved portion；Punching press cross cutting
Mold is divided into several stations, and the upper mold of each station has die cutter sword, and lower die has corresponding material-dropping hole；The stamping die
It cuts mold and is divided into four stations, the first cross cutting blade of the first station is divided into four fan blades, the position of four fan blades
Fan-shaped region position between the winding section of silicon steel sheet is corresponding, outwardly projecting with one in the middle part of the outer arc of each fan blades
Taper blade, the fracture site between taper blade edge position and the curved portion on the outside of silicon steel sheet is corresponding, and the width of the taper blade
Degree is less than the width of fracture；There are four rectangle blades corresponding with winding section rectangular opening for second die cutter cutlery of second station；
The third die cutter cutlery of 3rd station has circular blade corresponding with the inner circle shape of central circular；4th mould of the 4th station
Cutoff edge has four curved blades corresponding with the curved portion of silicon steel sheet and fracture.
Using the utility model die-cutting mould, after the first cross cutting blade, what fan blades and taper blade were cut
Region not fully achieved the fan-shaped region of silicon steel sheet and the size of fracture site, so that finally cross cutting forms curved portion and breaks
When mouth, there is material surplus in the periphery of curved portion end, and curved portion generates alice or injustice when so as to prevent from being finally punched
Phenomenon keeps silicon steel sheet surface smoothness higher.Using the utility model punching press die-cutting mould can make the qualification rate of silicon steel sheet by
80% or so is increased to 98% or more.
Detailed description of the invention:
Fig. 1 is the floor map of silicon steel sheet；
The planar structure schematic diagram of Fig. 2 the utility model mold.
Specific embodiment:
The present invention will be further described with attached drawing combined with specific embodiments below.
First as shown in Figure 1, using the utility model die-cutting mould silicon steel sheet produced floor map, the silicon steel
Piece 5 has a central circular 51 and is uniformly arranged on four winding sections 52 of 51 periphery of central circular, each winding section 52
Equipped with a rectangular opening 521, the outer end of winding section 52 is equipped with arc-shaped curved portion 53, has one to break between adjacent curved portion 53
Mouth 54；
Again as shown in Fig. 2, described in the utility model is that one kind can prevent the punching press of silicon steel sheet alice injustice phenomenon to be die cut
Mold, the punching press die-cutting mould are divided into four stations, and the upper mold of each station has die cutter sword, and lower die has corresponding
Material-dropping hole (in figure slightly)；Wherein: the first cross cutting blade 11 of the first station 1 divides for four fan blades, four fan blades
Fan-shaped region position between position and the winding section 52 of silicon steel sheet 5 is corresponding, have in the middle part of the outer arcs of each fan blades one to
54 position pair of fracture between curved portion 53 on the outside of outer taper blade 111 outstanding, taper blade edge position 111 and silicon steel sheet 5
It answers, and the width of the taper blade 111 is less than the width of fracture 54；Second station 2 second cross cutting blade 21 tool there are four with
The corresponding rectangle blade of 52 rectangular opening of winding section 521；3rd station 3 third cross cutting blade 31 have in central circular 51
The corresponding circular blade of round；4th cross cutting blade 41 of the 4th station 4 has curved portion 53 and fracture 54 with silicon steel sheet 5
Corresponding four curved blades.
Using the utility model die-cutting mould, after the first cross cutting blade 11, fan blades and taper blade are cut
Region not fully achieved silicon steel sheet 5 54 position of fan-shaped region and fracture size, so that finally cross cutting form arc
When portion and fracture, there is material surplus in the periphery of 53 end of curved portion, and curved portion generation is stuck up when so as to prevent from being finally punched
Side or uneven phenomenon, keep silicon steel sheet surface smoothness higher.Silicon steel sheet can be made using the utility model punching press die-cutting mould
Qualification rate is increased to 98% or more by 80% or so.
