Wire tensioning device for multi-wire coil

Abstract

A wire tensioning device for a multi-wire coil comprises a base, a plurality of wire pulling devices, and a plurality of traction devices. Each of the wire pulling devices comprises a gravity hammer,a pulley block, a fixed seat, and a traction rope. The traction rope is hung on the pulley block. The pulley block comprises three pulleys that are arranged in an L shape. Each of the traction devicescomprises a traction rail mechanism, a traction hook, and a traction pulley. The stress direction of the traction hook is opposite to the stress direction of the traction pulley. The traction rope onthe traction pulley is located between the fixed seat and the pulley block. By using the traction devices and the wire pulling devices, the wire tensioning device for a multi-wire coil can avoid theinconsistency of the tightness of the wires wound around inner and outer coils due to the difference of inner and outer diameters of the coils, thereby improving the quality of the coils.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a wire tensioning device for multi-wire coils. Background technique [0002] A winding machine is a machine that winds a wire-like object onto a specific workpiece. Most electrical products need to be wound with enameled copper wire (referred to as enameled wire) to form an inductance coil, and a winding machine is required. The manufacturing and processing of a single series air-core coil in the electronics industry usually requires the use of a spindle drive. The spindle driving device is used to clamp the bobbin of the coil, so as to wind the wire on the bobbin while rotating the bobbin. [0003] For some layered coils, in order to increase the winding speed of the layered coil, multiple wires are usually wound together to form a coil at the same time. Therefore, it is conceivable that each turn of the coil is composed of multiple wires, and the multiple wires ...

AI Technical Summary

Problems solved by technology

Therefore, in the process of winding, since the tail wire of the wire is fixed by the clamping mechanism, and because the wire inside each turn of the coil will use the least amount of wire, and the wire outside each turn of the coil will use the most , so after a period of time, the inner wire will become loose and the outer wire will become tighter. Such inconsistent inner and outer tightness will affect the quality of the wound coil
