A wire and cable rotary mold

Abstract

The invention discloses a wire / cable spinning mould, comprising a base, a thrust self-aligning roller bearing, a gear sleeve, a stranding die, an upper pressing cover, a signal pick-up device, a controller and a servo motor, wherein the thrust self-aligning roller bearing is arranged in each of the base and the upper pressing cover, the thrust self-aligning roller bearing is in interference fit with the gear sleeve, an external gear is arranged at one end of the gear sleeve, fastening antiskid bolts are arranged at the other end of the gear sleeve, the stranding die is in fixed connection with the gear sleeve by means of the fastening antiskid bolt, an in-die hole, a stranding tapered hole and a die exit are formed in the stranding die, and base fastening bolts are arranged at the lower part of the base. According to the wire / cable spinning mould disclosed by the invention, as the controller and the signal pick-up device are employed to acquire a spinning speed of an equipment stranding body, and a frictional force that is exerted by the stranding die in a tangential direction is eliminated by means of a synchronous and homodromous rotation of the servo motor and the spinning mould; the spinning mould has the advantages of small volume, low cost and long service life; material wastage is reduced by 15-20%; the one-time delivery qualification rate can reach 98-100%; and the product quality is improved greatly.

Description

technical field [0001] The invention relates to the field of cable mold technical equipment, in particular to a wire and cable rotary mold. Background technique [0002] With the continuous development of the wire and cable industry, the structural requirements for wire and cable products are getting higher and higher. The structural characteristics of wire and cable products are composed of a variety of structural elements. The two processes of conductor stranding and cable forming are indispensable for wire and cable products. The paralleling mold is the key molding tool used in these two processes. Multiple metal conductors or multiple insulated core wires are installed on the equipment twisted body, and are connected to the traction rope through the inner hole of the paralleling mold. Under the pulling force of the traction rope, it moves along the axial direction of the paralleling mold, and at the same time, the equipment strand and the aperture center of the paralleli...

AI Technical Summary

Problems solved by technology

[0003] The shortcoming or deficiency of the prior art is that the paralleling mold is fixed on the equipment and remains still, and the friction force in the tangential direction generated by the wire body composed of the paralleling mold and the metal conductor or insulating core wire makes the surface of the metal conductor or insulating core wire Wear and tear directly affects product quality, high scrap rate, low product qualification rate, resulting in unstable product quality
