Problems solved by technology

However, since the amorphous alloy strip, especially the annealed amorphous alloy core is more sensitive to mechanical stress, the three-phase clamping method will obviously affect the electromagnetic properties of the amorphous alloy core, so the traditional silicon steel sheet three-dimensional wound core winding machine Unable to apply to amorphous alloy three-dimensional wound core

Embodiment Construction

[0013] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0014] Such as figure 1 , figure 2 As shown, the present invention includes a coil mold 1, a rotating gear 2, a fixed platform 3, a workbench 4, an elevator 5, and a wire wheel 6.

[0015] The main function of the coil mold 1 is to support the binding force of the wire when the coil is wound, avoiding the direct force on the iron core, so as to avoid the decrease of the electromagnetic performance of the iron core due to the binding stress of the wire during the winding process. The coil mold 1 can be a rigid detachable mold 1, or a specially designed insulating part that will eventually be a part of the transformer.

[0016] There are 6 rotating gears 2 in the present invention, two coils for each phase, distributed...

Abstract

The invention relates to a vertical winding machine for transformers with amorphous alloy three-dimensional wound iron cores. The vertical winding machine comprises coil molds, rotary gears, a fixing table, wire wheels and motors. Three vertical iron cores are fixed onto the fixing table, each detachable coil mold sleeves the corresponding iron core, the corresponding rotary gears are mounted on the upper side and the lower side of each coil mold, the motors are connected with driving gears, the driving gears are meshed with the rotary gears, wires which are used for being wound on the coil molds are stored on the wire wheels, and tensioning force can be provided by the wire wheels when the wires are about to be wound. The vertical winding machine has the advantages that iron core turnover procedures can be reduced owing to a vertical winding method, stress on the iron cores in horizontal clamping and turnover procedures can be eliminated, the wires can be simultaneously wound on three phases, and accordingly the integral coil winding efficiency can be improved.

Description

technical field [0001] The invention relates to a winding machine, more specifically, to a vertical winding machine for an amorphous alloy three-dimensional wound core transformer. Background technique [0002] The amorphous alloy three-dimensional wound core transformer is an energy-saving and environment-friendly transformer, and its no-load loss is much smaller than that of conventional transformers. The winding process is a key process in the transformer manufacturing process. The existing silicon steel sheet three-dimensional winding core transformer winding adopts a three-phase clamping horizontal winding method. The main method is to set a detachable mold on the outer wall of the core, and carry out the wire winding by rotating the mold. Winding. However, since the amorphous alloy strip, especially the annealed amorphous alloy core is more sensitive to mechanical stress, the three-phase clamping method will obviously affect the electromagnetic properties of the amorp...
