Problems solved by technology

However, in actual use, due to the special structure of the steel wire rope, there is a certain gap between the strands. Even if the clamping element at the bottom of the mold is in full contact with the wire rope, the existence of the gap cannot be avoided, which leads to The molten liquid is easy to leak from the gap during casting, which will cause the leakage of the alloy liquid and seriously affect the safety of production

Embodiment 1

[0031] A method for preventing leakage of alloy liquid during the preparation of steel wire rope samples. The steel wire rope 300 is bundled near both ends. The binding part 310 divides the steel wire rope 300 into a pouring part 330 and a tensile test part 320. The pouring part 330 is located at the end of the steel wire rope 300 department. Then the pouring part 330 is opened to make it dispersed, and then the scattered pouring part 330 is fully cleaned to ensure that the steel wires from the binding part 310 to the end of the steel wire rope 300 are free of grease and foreign matter. Then the steel wire rope 300 is passed through the through hole of the mold 100 , so that the pouring part 330 of which one end of the steel wire rope 300 has been cleaned is located in the inner cavity of the mold 100 , and the through hole of the mold 100 is filled by the binding part 310 . Then fill the gap between the side of the binding part 310 close to the pouring part 330 and the outer ...

Abstract

The invention discloses a method for preventing an alloy liquid from leaking in a preparation process of a steel wire rope sample, and a testing method of a breaking force of a steel wire rope, and relates to the technical field of steel wire rope performance detection. The method for preventing the alloy liquid from leaking in the preparation process of the steel wire rope sample comprises the step of filling a leak preventive near a binding part of the steel wire rope prior to casting of the alloy liquid, wherein a fusion point of the leak preventive is higher than a fusion point of the alloy liquid; the leak preventive is granular. The method can prevent the alloy liquid from leaking in the preparation process of the steel wire rope sample. The testing method of the breaking force of the steel wire rope comprises the step of performing breaking force testing on the steel wire rope sample obtained by the method for preventing the alloy liquid from leaking in the preparation process of the steel wire rope sample. A testing result is more accurate.

Description

technical field [0001] The invention relates to the technical field of steel wire rope performance detection, and in particular to a method for preventing alloy liquid leakage during the preparation of a steel wire rope sample and a method for testing the breaking tension of the steel wire rope. Background technique [0002] The alloy casting method is the most commonly used method for the breaking force test of the whole steel wire rope. After the two ends of the sample are bound and the ends are loosened and cleaned, they are cast with a molten alloy with a low melting point. After cooling to room temperature, the A method of performing tensile tests on a tensile testing machine. The Chinese patent with the application number 201210091982.0 proposes a method for detecting the breaking force of the entire steel wire rope, which belongs to a kind of alloy casting method, and better solves the problems of detecting the breaking force of the entire steel wire rope and preparin...
