Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel wire rope production and processing, and specifically relates to a steel wire rope stress relief device. Background Art
[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. Steel wire rope is composed of steel wire, rope core and grease. Steel wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, it is used for lifting, traction, tensioning and bearing. Steel wire rope has high strength, light weight, stable operation, not easy to break suddenly, and reliable operation. In the manufacturing process of steel wire rope, it is inevitable to generate certain stress. It is necessary to use a stress relief device to remove the stress on the steel wire rope to ensure the quality of the steel wire rope.
[0003] According to the patent application number 202220728694.0, a wire rope stress relief device is disclosed, including a bracket, a support frame, a rotating assembly, a cleaning assembly and a stress relief assembly. The stress relief assembly is located on the support frame and contacts the surface of the wire rope. It is used to press wire ropes of different diameters to complete the stress relief operation of the wire rope. The support frame is rotatably connected to the bracket so that the support frame can rotate on the bracket. The wire rope passes through the support frame. The cleaning assembly on the inside of the support frame can clean the surface of the wire rope to facilitate subsequent stress relief operations; the stress relief assembly can press the wire rope and remove the stress of the wire rope.
[0004] Although the stress relief component can be adjusted by the above technical solution to facilitate stress relief for steel wire ropes of different diameters, the above technical solution still has certain defects when used. The above solution cannot cool the stress relief component when used. The stress relief component rubs against the steel wire rope at high speed when used, causing the stress relief component to heat up after working for a long time, thereby affecting the service life of the stress relief component.
