Detailed Description
The present invention will be further described with reference to fig. 1 to 4.
The utility model relates to a scattered piece, it includes piece body 11, the middle part shaping of piece body 11 has the rotor through-hole, shaping a plurality of wire winding groove 12 on the piece body 11, each wire winding groove 12 encircles the rotor through-hole and distributes, structure between two adjacent wire winding grooves 12 is yoke portion 13, the both sides of 13 front ends of yoke portion shape respectively has the wire winding bellying that is located the 12 notches of corresponding wire winding groove, the shaping of piece body 11 has a plurality of mounting hole, it has die-cut waste piece 14 to reserve in the mounting hole, die-cut waste piece 14 is connected with the lateral wall of mounting hole through at least three reservation muscle 16, respectively reserve 16 along circumference evenly distributed of muscle.
The side surface of the punching waste sheet 14 is formed with a self-fastening point 15, one side of the self-fastening point 15 is formed as a self-fastening convex part, and the other side of the self-fastening point 15 is formed as a self-fastening concave part.
The above structure is the first embodiment of the scattering sheet, and the scattering sheet described in the first embodiment can be regarded as a convex scattering sheet. The difference between the second embodiment of the loose piece and the first embodiment is that the self-fastening point 15 on the punched waste piece 14 is formed as a self-fastening through hole 17, the self-fastening through hole 17 can be used for the self-fastening protrusion of the protruding loose piece to extend into, and the loose piece described in the second embodiment can be regarded as a through piece.
The utility model relates to a self-clinching iron core, it includes a plurality of scattered piece, and the structure of scattered piece is like embodiment structure, and each scattered piece is range upon range of to be arranged, and the protruding portion correspondence of detaining of the self-clinching of the scattered piece of lower one deck is located the self-clinching depressed part of the scattered piece of upper one deck. The yoke parts 13 of each loose piece are laminated to form the stator yoke part, and the self-fastening iron core further comprises a plurality of metal winding wires which are arranged on the stator yoke part.
When the self-buckled iron core is manufactured, the self-buckled convex parts and the self-buckled concave parts of the punched waste sheets 14 are utilized to fix the scattered sheets in a laminated mode, after metal winding is fixed, the reserved ribs 16 of the punched waste sheets 14 are cut off by adopting a punching process, and therefore the situation that a convex self-buckled structure is left on the manufactured stator is avoided.
The utility model relates to a from detaining the iron core, it is including leading to the protruding piece that looses of piece and a plurality of, and each protruding scattered piece is range upon range of to be arranged, and the protruding bellying correspondence of detaining of lower one deck is located the protruding sunken part of detaining of the one deck certainly that looses, leads to the piece and installs the upside at the protruding piece that looses of top layer, and the protruding bellying correspondence of detaining of the protruding piece of top layer is located the through-hole 17 of detaining certainly that leads to the piece. The self-buckling through hole 17 is designed to avoid the existence of a raised self-buckling structure on the structure obtained by stacking and fixing the scattered sheets.
