Reusable conductor joint die and production method for joint die body thereof

Abstract

The invention discloses a reusable conductor joint die and a production method for a joint die body thereof, and relates to the technical field of cable processing. The joint die comprises the joint die body and a joint die hoop used for hooping the joint die body; the joint die body includes two semi-cylindrical half die bodies symmetrically arranged; a semi-cylindrical groove is formed in the inner side face of each half die body in the axis direction of the half die body; the two half die bodies are combined to make the two grooves spliced to form a through hole for a conductor to pass through; the joint die hoop includes an arc-shaped upper half hoop and lower half hoop; and the upper half hoop is hinged with one end of the lower half hoop, and detachably connected with the other end of the lower half hoop. According to the reusable conductor joint die and the production method for the joint die body thereof, after a conductor joint is welded, the conductor joint die can be easilytaken down and repeatedly used, so that the pollution to the environment is reduced, and production cost is reduced to a great extent.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a reusable conductor joint die and a production method for the joint die body. Background technique [0002] In the production process of cross-linked three-layer co-extruded insulation process of medium and high voltage cables, the end of the conductor needs to be welded when the conductor is changed or the specification is changed. The joint mold is required in the welding process, and the existing joint mold is integral. The cylindrical structure is generally made of phosphate material. The specific welding operation is to insert and contact the ends of the two conductors from the holes at both ends of the conductor joint mold. The purpose of welding the end is achieved, but after the welding is completed, the conductor joint mold has been placed on the conductor. If you want to quickly remove the conductor mold, you need to smash it into pieces and discard it. [00...

Problems solved by technology

[0002] In the production process of cross-linked three-layer co-extruded insulation process of medium and high voltage cables, the end of the conductor needs to be welded when the conductor is changed or the specification is changed. The joint mold is required in the welding process, and the existing joint mold is integral. The cylindrical structure is generally made of phosphate material. The specific welding operation is to insert and contact the ends of the two conductors from the holes at both ends of the conductor joint mold. The purpose of welding the end is achieved, but after the welding is completed, the conductor joint mold is always set on the conductor. If you want to quickly remove the conductor mold, you need to smash it and discard it

[0003] The disadvantage of this method is that: on the one hand, it is a waste of cost. The cost of a conductor joint die reaches about 5 yuan. With the continuous improvement of requirements, a large number of such conductor joint molds will cause certain pollution to the environment after being discarded. Therefore, the suppliers of this type of conductor joint molds have gradually decreased, and the problem of difficult procurement has arisen.
