Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] like figure 1 As shown, the present invention is described by taking the cable joint casting of a steel wire rope with a diameter of φ37mm as an example.
[0024] The present invention comprises the steps:
[0025] 1) Cut off the hemp core at the end of the steel wire rope 1 with a diameter of φ37mm at an appropriate position, and tie it with a thin iron wire 3 with a diameter of φ1.2mm close to the end, spread out the end of the steel wire rope 1 and straighten it into a Bundle the steel wires 4, then carry out sandblasting to the scattered steel wires 4 and clean them with alcohol. The loose steel wire 4 can not be straightened, and when the loose steel wire 4 is cleaned, if it can be cleaned with alcohol, it can be cleaned without sandblasting.
[0026] 2) The casting body 5 is sandblasted and cleaned with alcohol. When cleaning the casting body 5, if it ...

Abstract
The invention discloses a casting method in which the casting body is filled with inert gas for protection, comprising the following steps: S1, binding and fixing the steel wire rope near the upper end with thin iron wires, spreading the thin iron wires of the steel wire rope to the upper end to form a bundle of steel wires and cleaning them; S2. Clean the casting body; S3. Insert the thin iron wire of the steel wire rope to the upper end into the casting body. The steel wire rope below the casting body is wrapped with asbestos cloth to realize the sealing of the gap between the steel wire rope and the bottom of the casting body; S4. Inert gas The pipe is inserted into the casting body, and the inner cavity of the casting body is filled with inert gas; the casting material is poured into the casting body at one time; S5, the cast cable joint is cooled to room temperature; S6, the end of the cable joint is clamped to meet the product use Require. The invention is easy to operate, greatly improves the casting quality of the cable joint, and increases the breaking force of the steel wire rope. The invention reduces the cast body of the cable joint and reduces the production cost of the cable joint.
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 ...
