Abstract

The utility model discloses a stamping die of integral type separation is taken to stator material, including stamping male die, the whole terrace die of stamping male die for covering a plurality of tooth, stamping male die have a plurality of tooth head processs that rectangular moulding -die part and moulding -die part has and rise. When stamping male die stamping working, tooth on the billot area and material area part by the moulding -die subtotal tooth head process of whole terrace die rise the institute push down, the tooth head and flute profile punching press separation in the two bankwinding grooves that stamping male die took the material when punching press is accomplished, are taken to recessedly corresponding to stamping male die's material, the horizontal direction is kept in another billot area on the punching press platform, the layering is separated voluntarily from top to bottom in two billot areas.

Description

The diel that a kind of stator material strip integral type is separated
Technical field
The present invention relates to field of motor manufacturing, be specially the diel that motor stator material strip tooth head flute profile integral type is separated.
Technical background
At present, the impact style of electric motor of automobile stator piece as shown in Figure 1, normally take punch 1 ' come punching, the flute profile punching press of the tooth head part of a material strip from another material strip disconnects in the tooth head part of teeth by punch blade, after punching press, tooth head, toward recessed, forms two interlaced intersections of material strip, as shown in Figure 2.The impact style used at present is all the corresponding each tooth head part of single punch 1 ', and with current knowhow, the product that this structure is produced exists two large defects: 1. there is punch impression c on tooth head part surface, difficult elimination.2., when this structure intersection tears separation, tooth head width (a) due to individual product is greater than flute profile distance (b) as shown in Figure 3, easily causes tooth head to be out of shape when tearing.
Summary of the invention
For the defect that said structure exists, the object of the present invention is to provide the diel that a kind of stator material strip integral type is separated, the material strip that punching press completes is separated layering automatically, can avoid tearing because intersecting the various problems caused.
For achieving the above object, be achieved by the following technical solution:
The diel that stator material strip integral type is separated, includes punching press punch, it is characterized in that: described punching press punch is the solid punch covering several teeth; Described punching press punch has multiple tooth head protrusions that rectangular compression molding portion and compression molding portion have.When punching press punch press work, article one, the teeth on material strip and material strip part by the compression molding portion of solid punch and tooth head protrusion push down, the tooth head of two row's slot for windings on material strip is separated with flute profile punching press by punching press punch, when punching press completes, corresponding to the material strip of punching press punch toward recessed, another material strip maintains horizontal direction on punching press platform, and two material strips are separated layering automatically up and down.
Further, described punching press punch is combined to form solid punch by several independent punching press punch, and independent punching press punch has the tooth head protrusion that rectangular compression molding portion and compression molding portion have.
The present invention compared to existing technology, eliminates the punch impression c on nipper head part surface of material, and the rear tooth-head avoiding punching press is past is sunken into the difficulty of capable formation two interlaced intersections of material strip from the situation of tearing separation.When especially requiring to need tooth head width (a) to be greater than flute profile distance (b) for specialities, prior art cannot realize separating two material strips smoothly when not causing tooth head to be out of shape.The present invention but can solve this problem smoothly.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 4,5, the diel that a kind of stator material strip integral type is separated, includes punching press punch 1, and described punching press punch 1 is the solid punch covering several teeth.Described punching press punch 1 has multiple tooth head protrusions 12 that rectangular compression molding portion 11 and compression molding portion 11 have.In the present embodiment a punching press punch have 6 tooth head protrusions.
Another kind of mode is exactly as shown in Figure 4, and described punching press punch 1 is combined to form solid punch by several independent punching press punch, and independent punching press punch has the tooth head protrusion that rectangular compression molding portion and compression molding portion have.
When punching press punch 1 press work, article one, the teeth on material strip and material strip part by the compression molding portion 11 of solid punch and tooth head protrusion 12 push down, the tooth head of two row's slot for windings on material strip is separated with flute profile punching press by punching press punch 1, when punching press completes, corresponding to the material strip of punching press punch 1 toward recessed, another material strip maintains horizontal direction on punching press platform, and two material strips are separated layering automatically up and down.
As shown in Fig. 4,6, a kind of method that stator material strip integral type is separated, the method enters forcing press by after discoid material strip uncoiling smoothing, and utilize step-feeding diel to carry out punching press, step is as follows, at material strip 2 middle precalculated position punching press sorting hole 3; on material strip 2, strike out two row's slot for windings 4; punching press punch 1 is utilized to be separated with flute profile punching press by the tooth head of two row's slot for windings 4 on material strip 2; wherein a material strip 21 corresponding to punching press punch is toward recessed, and another material strip 22 maintains horizontal direction on punching press platform, and two material strips 21,22 are separated layering automatically up and down; multiple sorting hole 3 forms separating belt and is divided into two by material strip 2, and the material strip often arranging slot for winding 4 is formed and is not connected mutually, on all four two the continuous stator material strips of size.
Adopt technical scheme of the present invention, eliminate the punch impression on nipper head part surface of material, and the rear tooth-head avoiding punching press is past is sunken into the difficulty of capable formation two interlaced intersections of material strip from the situation of tearing separation.When especially specialities being required to need tooth head width (a) to be greater than flute profile distance (b), prior art cannot realize separating two material strips smoothly when not causing tooth head to be out of shape, even if tear by force, tooth head can be out of shape, and the present invention solves this problem smoothly.Described in upper, it is only better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solutions of the utility model.
