Adjustable die for transformer coil winding

Abstract

The invention discloses an adjustable die for transformer coil winding. The adjustable die comprises a die body, and is characterized in that the die body comprises a winding sleeve composed of at least four die sections, and the inner side of each die section is connected with a hollow die shaft through a hinge; a die center shaft penetrates through the hollow die shaft; the die center shaft is composed of a middle section, a threaded section and a cube section, the threaded section and the cube section are arranged on the two sides of the die center shaft, the middle section is matched with the hollow die shaft, the cube section penetrates through the center of a second spoke disc, the threaded section penetrates through the center of a first spoke disc, the threaded section is sleeved with a shaft sleeve, and the shaft sleeve is in threaded connection with the threaded section; the shaft sleeve is provided with a limiting structure, the shaft sleeve end on one side of the limiting structure penetrates through the first spoke disc, and the first spoke disc is limited at the limiting structure. The adjustable die is high in universality, the variable diameter of the die body can be suitable for manufacturing of different types of coils, production cost is greatly reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to an adjustable die for transformer winding, which is used for winding transformer coils and belongs to the technical field of electrical engineering. Background technique [0002] As the heart part of the transformer, the coil plays an important role in carrying the current and changing the voltage. In the design process of the transformer, in order to meet the requirements of the manufacturing cost and performance of the transformer, usually the inner and outer diameters of the coils of different capacities, Parameters such as height, number of turns, wire cross-section used are different. Since the coil is the core component that carries current and transmits electric energy, it is necessary not only to ensure that the materials of various materials meet the requirements of electrical, mechanical and thermal properties during operation, but also to ensure that the winding is completed. The overall dimensions meet the design r...
