Casting method for filling inert gas into casting body for protection

Abstract

The invention discloses a casting method for filling inert gas into a casting body for protection. The casting method comprises the following steps that S1, the part, close to the upper end, of a steel wire rope is binded and fixed by adopting a thin iron wire, and the uppermost end of the thin iron wire of the steel wire rope is scattered into a bundle of steel wires and cleaned; S2, the castingbody is cleaned; S3, the part at the uppermost end of the thin iron wire of the steel wire rope is inserted into the casting body, and the steel wire rope below the casting body is wrapped with asbestos cloth to seal a gap between the steel wire rope and the bottom of the casting body; S4, an inert gas pipe is inserted into the casting body, the inner cavity of the casting body is filled with inert gas, and a casting material is poured into the casting body at a time; S5, a cast cable joint is cooled to the room temperature; and S6, the end of the cable joint is clipped to meet the use requirement of a product. The casting method is convenient to operate, the casting quality of the cable joint is greatly improved, the breaking force of the steel wire rope is improved, the casting body of the cable joint is reduced, and the production cost of the cable joint is reduced.

Description

technical field [0001] The invention belongs to the technical field of cable joint manufacturing methods, and in particular relates to a casting method in which a casting body is filled with inert gas for protection. Background technique [0002] Cable joints are divided into open type cable joints and closed type cable joints. The casting process of the two types of cable joints is basically the same. The main process is: ①Scatter and clean the steel wire rope at the part to be cast; ②Clean the cast body and mix it with Assemble the steel wire rope to the design requirements; ③Wrap and seal the casting body and steel wire rope with asbestos mud and asbestos cloth at the bottom of the casting body; ④Pour the casting material heated to a certain temperature into the casting body; ⑤Wait for the casting material in the casting body to cool After reaching room temperature, clamp the end of the casting body, and thus complete the casting of the cable joint. Due to the small gap ...

AI Technical Summary

Problems solved by technology

Based on the above two reasons, the cast cable joints we have seen have larger dimensions, larger weight, more materials, and higher production costs.
