AI Technical Summary

Technical Problem

On the Ф630 cage winding head, the inner diameter of the support sleeve and the outer diameter of the wire guide die are significantly different, resulting in loose and uneven wrapping of the steel strip, which affects the wrapping quality and production efficiency of the superconducting cable.

Method used

Design a wire guide die holder device for the inlet of the winding head of a cage strander, including a hollow shaft, a support sleeve, a pressure cover, a die holder and a wire guide die, which are fixed by screws to ensure smooth and tight winding of steel strip. The diamond aggregate wire guide die using polycrystalline wire drawing die avoids jumping.

Benefits of technology

This method achieves tight and smooth steel strip wrapping, improving the wrapping quality and production efficiency of superconducting cables, avoiding damage during the wrapping process, and enhancing product quality and machine efficiency.

Abstract

The utility model discloses a wire passing die holder device for a wire inlet of a wrapping head of a cage strander, and belongs to the technical field of cable production equipment. Comprising a hollow shaft, a supporting sleeve, a gland, a die holder and a wire passing die, the left end of the supporting sleeve is inserted into the right end of the hollow shaft, the wire passing die is inserted into the left end of the die holder, the die holder is inserted into the right end of the supporting sleeve, the gland is composed of a cylinder with internal threads and a cover plate integrally formed at the end of the cylinder, and external threads are arranged on the outer wall of the right end of the supporting sleeve. Cylinder threads of the gland are arranged at the right end of the supporting sleeve. According to the utility model, violent jumping generated in the circumferential direction of the inlet of the superconducting cable when the superconducting cable is wrapped by the steel belt can be avoided, so that the steel belt is smooth to take, the wrapped steel belt is tight and flat, the overlapping rate of the steel belt wrapped on the surface of the produced superconducting cable is ensured to meet the process requirement, and the production efficiency is improved. The superconducting cable is prevented from being damaged in the steel belt wrapping process, the product quality is improved, and the production efficiency of a machine table is also improved.
