An electromagnetic coil winding tool

Abstract

The invention discloses an electromagnetic coil winding tool, comprising a base and a profiling die made according to the shape of the coil. The profiling die is fixedly connected with the base through a plurality of bolts, and symmetrically arranged rotary shaft mounting holes are opened in the middle of the profiling die. , The rotary shaft is installed in the installation hole of the rotary shaft. The rotary shaft is installed with a wrench on the upper part of the profiling die. The middle of the wrench passes through a pressing wheel shaft. A cut annular groove is provided, the shaft of the pressing wheel is on the outside of the profiling die, and a gap is arranged between the wheel surface of the pressing wheel and the side surface of the profiling die. The overall structure is simple, the processing is simple, the manufacturing difficulty is low, and it has high economic efficiency; the production cycle is short, and it can quickly respond to the requirements of production tasks; the precision is reliable, the operation is convenient, the requirements for operators are low, and labor costs are saved; it has a large The versatility of the coil, for different sizes of coils, only need to replace the copying die.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic equipment, in particular to an electromagnetic coil winding tool. Background technique [0002] Electromagnetic equipment is a kind of equipment that relies on electromagnetic coils to provide electromagnetic fields, which act on the objects to be worked and manifest as force, rotational torque or eddy current heating; electromagnetic coils are the core components of electromagnetic equipment, and their external dimensions and electrical parameters vary widely. There are also many kinds of electromagnetic wires, which can be divided into copper wire and aluminum wire according to the material; according to the cross-sectional shape, it can be divided into solid wire such as round wire and flat wire, and hollow pipeline such as round tube, square tube and waist-shaped flat tube; According to the insulation material, it can be divided into enameled wire and silk covered wire.

AI Technical Summary

Problems solved by technology

Hollow pipelines are characterized by large cross-sectional dimensions and hollowness. However, winding coils with hollow pipelines requires high winding tension and the risk of pipe collapse

[0005] Some electromagnetic equipment such as electromagnetic stirrers or electromagnetic heaters for metallurgy are equipped with special-shaped coils, such as waist-shaped coils. For such coils, the conventional single-axis cylindrical rotary winding cannot be used
