Enameled wire high-speed stranding device

Abstract

According to the enameled wire high-speed stranding device provided by the utility model, an enameled wire to be stranded on a wire bearing wheel sequentially passes through an annular wire bearing groove and a threading hole to enter a wire stranding groove, and the stranding operation is completed in the wire stranding groove. Specifically, the rotating motor drives the rotating disc to rotate to drive the raw material fixing mechanisms and the pressing mechanisms to rotate so as to complete twisting operation. When a to-be-twisted enameled wire needs to be fastened, on one hand, fastening can be carried out through the extrusion assembly. Specifically, the extrusion cylinder drives the friction pad to be extruded and fixed on the wire bearing wheel through the extrusion block so as to limit the rotation of the wire bearing wheel or extrude and fix the wire bearing wheel. Therefore, the effect of fastening the to-be-twisted enameled wire is achieved. And on the other hand, the operation can be performed through a pressing mechanism, specifically, a threaded rod is rotated by rotating a handle, the threaded rod moves downwards in the rotating process, and a U-shaped sliding plate is driven by a rotating plate to drive an extrusion wheel to perform extrusion speed limiting or limiting on the to-be-twisted enameled wire in an annular wire bearing groove.

Description

Technical Field

[0001] The utility model relates to the field of wire stranding equipment, in particular to a high-speed wire stranding device for enameled wires. Background Art

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. After annealing and softening, the bare wire is then repeatedly coated and baked. However, producing enameled wire that meets both standard requirements and customer specifications is challenging. Enameled wire's quality characteristics vary widely, influenced by factors such as raw material quality, process parameters, production equipment, and environmental factors. However, all possess four fundamental properties: mechanical, chemical, electrical, and thermal properties. Enameled wire is a primary raw material for products such as motors, electrical appliances, and household appliances. In recent years, the power industry has experienced sustained and rapid growth, and the rapid development of household appliances has broadened the application scope of enameled wire.

[0003] However, when twisting enameled wire, a stranding machine is required.

Conventional stranding machines, such as the one disclosed in patent application number CN200620124296.9, have a poor tightening mechanism for single-strand wires and cannot meet the demand for high-strength finished products.
