Problems solved by technology

The problems of this traditional block-type adjustable winding die are: 1. The diameter adjustment accuracy of the winding die is low, and the thinnest specification of the block is 1 mm, so the error of each stay within 0-1 mm cannot be adjusted ;2. When making paper tube coils, it needs to be equipped with diagonal stays before use. The diagonal stays need to be inserted one by one, which is time-consuming and laborious. In addition, because the ends of the diagonal stays are damaged quickly, they are the most consumed parts in the tooling. 3. It is difficult to demould, and it is necessary to cooperate with the drafting table to demould. The huge friction force during demoulding may cause damage to the winding, and even damage the insulation layer in severe cases.

Embodiment Construction

[0019] see Figure 1-3 , the present invention consists of a mold body 1, a spacer 5 and an adjustable stay assembly, the spacer is used for coarse adjustment of the diameter of the winding die, and the adjustable stay assembly is uniformly arranged around the outer periphery of the mold. In order to realize the free and accurate adjustment of the diameter of the winding die within a certain range, the key technology of the present invention is embodied in the design of the adjustable stay assembly. The adjustable stay assembly includes a stay body 3 , an adjustment screw 7 , a shaft base 2 and a rotating shaft 4 . The shaft base is used to support the rotating shaft, and it is evenly fixed on the mold body along the axial direction of the winding mold. Connect the hook block 8, and the hook block is fixed with the mold body. The oblique chute 3-2 is uniformly distributed on the stay body, and the rotating shaft 4 passes through the oblique chute and its two ends are support...

Abstract

The invention relates to a transformer coil coiling mould capable of being finely adjusted, used for solving the problems that a diameter of a coiling mould can not be adjusted, the coiling mould is difficult to demould, and the like. The transformer coil coiling mould capable of being finely adjusted comprises a mould body, a cushion block and an adjustable brace subassembly, wherein the adjustable brace subassembly comprises a brace body, an adjusting nut, a shaft base and a rotating shaft, the shaft base is axially and evenly fixed on the mould body along the coiling mould, the end of the shaft base positioned on the top end of the mould body is provided with an adjusting screw hole, tip chutes are evenly distributed on the brace body, the rotating shaft passes through the tip chutes, both ends of the rotating shaft are supported by the shaft base, and the top end of the brace body is provided with an adjusting screw which is matched with the adjusting screw hole by screw threads. The transformer coil coiling mould can conveniently finely adjust the diameter of the coiling mould within a small range by only rotating the adjusting screw. The transformer coil coiling mould capable of being finely adjusted has the advantages that: firstly, the diameter of the coiling mould is adjusted in high precision; secondly, when a fiber container coil is manufactured, the traditional inclined brace is washed out so as to reduce the work assembly and increase the work efficiency; and thirdly, the transformer coil coiling mould can easily demould without a demoulding table.

Description

technical field [0001] The invention relates to a mold for preparing transformer coils, in particular to a transformer coil winding mold which can conveniently adjust the diameter of the winding mold in a small amount, and belongs to the technical field of transformer manufacturing. Background technique [0002] In the process of transformer production, coils need to be made with the help of winding dies. At present, the pad-type adjustable winding die is a kind of winding die widely used in the transformer industry. It is a special die for winding cylindrical coils. The basic structure of this type of winding die is composed of a cylindrical die body, pads and stays. There are a number of evenly distributed threaded holes on the outer circle of the die, and the stays and pads are fastened to the die body by hexagon socket screws. On the circumference, the diameter of the mold body ranges from φ310mm to φ2100mm (the diameter increases by 100mm for a step), and the mold body ...
