Description

Core block device for winding three-dimensional wound iron core

Technical Field

The utility model relates to a coiling pellet particularly, is a pellet device that is used for coiling three-dimensional book iron core.

Background

When the wound iron core is produced, the silicon steel sheet is required to be wound along the edge of the core block, then the wound silicon steel sheet is bound and fixed on the core block, and after the annealing is finished, the wound iron core is taken down.

The traditional core block is a complete plate body, and after winding is completed, the wound core is in close contact with the core block and is difficult to remove. In order to solve the problem, a person skilled in the art changes the core block into a split structure, as shown in fig. 4, the core block includes a plate-shaped main body 1 and two edge strips 2, and two longer opposite sides of the main body 1 are respectively provided with a long groove for accommodating the edge strips 2. Before winding, the edge strip 2 is embedded into the long groove, one end of a silicon steel sheet (material strip) is inserted into the clamping groove 1-2 on the main body 1, and the rotating shaft penetrates through the three circular positioning holes 3 on the main body 1 and drives the core block to rotate. When the wound iron core needs to be taken down, the edge strips 2 are knocked off to generate a gap required for disassembly, and then the wound iron core is taken down.

However, when the core block rotates at a low speed and the silicon steel sheet is not preliminarily wound, the edge strips 2 are easily separated from the elongated slots by the centrifugal force, and therefore, before winding, the two edge strips 2 must be locked by using an adhesive tape. During the annealing process, the tape burns off and the tape is reused to secure the edge strip 2 before the next winding. The process of using the tape increases the working time and reduces the efficiency. Moreover, the tape also increases the gap between the silicon steel sheet and the core block, which affects the winding quality.

On the other hand, the existing binding mode is integral binding, which is not firm enough, and the binding belt is easy to slide from the iron coil core.

SUMMERY OF THE UTILITY MODEL

The utility model provides a spool up solid core block device of rolling up unshakable in one's determination, its purpose: (1) the problems of low efficiency and incapability of ensuring the winding quality caused by the adhesive tape are solved; (2) the problem of current mode of tying up is firm inadequately is solved.

Detailed Description

The technical scheme of the utility model is explained in detail below with the attached drawings:

referring to fig. 1 to 3, a core block device for winding a three-dimensional wound core includes a body 1 and two edge bars 2.

The main body 1 is plate-shaped, and the middle part of the main body is provided with three positioning holes 3 which are used for being matched with a round shaft on a rotating shaft.

Two longer opposite sides of the main body 1 are respectively provided with a long groove for embedding the edge strip 2, and the other two shorter opposite sides are arc edges 1-1. One of the arc edges 1-1 is also provided with a clamping groove 1-2.

Furthermore, the shapes of the edge strips 2 and the long grooves are matched and are isosceles trapezoids. The upper bottom of the isosceles trapezoid is positioned at the outer edge of the pellet device, and the lower bottom of the isosceles trapezoid is positioned at the groove bottom of the long groove. The upper base, the lower base and the waist follow the conventional definition of an isosceles trapezoid, namely, the longer base is the lower base and the shorter base is the upper base.

The groove bottom of the long groove is also provided with three grooves 5 which are respectively positioned in the middle and two ends of the groove bottom of the long groove.

Further, still be equipped with four rectangular through-holes 4 on the main part 1, every elongated slot corresponds two rectangular through-holes 4. The strip through hole 4 is positioned at the inner side of the middle position of the groove 5 at the end part and the groove 5 at the middle part of the long groove. And a chamfer is arranged at the orifice of the long strip through hole 4, so that the abrasion of the strapping tape is reduced.

The process of manufacturing the wound core by using the device is as follows: firstly, a rotating shaft penetrates through a round hole in a main body 1, an edge strip 2 is placed in a long groove, then one end of a silicon steel sheet is inserted into a clamping groove 1-2, and then under the action of the rotating shaft, a core block drives one end of the silicon steel sheet to rotate to start winding. In the winding process, the edge strips 2 cannot be separated from the long grooves due to the blocking of the bevel edges 2-1 at the two ends of the edge strips 2. After winding is completed, the wound core is cross-bound from different angles using a binding tape through the groove 5 and the elongated through hole 4. After the annealing is completed, the binding band is removed, then the edge strips 2 are knocked off, and finally the wound core is taken off from the core block.
