Problems solved by technology

The core of the earliest compacted steel wire rope was made of sisal or jute. During the compaction process, due to the large impact force of the steel wire rope, the rope core composed of sisal or jute was broken under the impact force (the composition of the rope core was 80 More than % of the fiber breaks), which reduces the stability of the steel wire rope structure, and structural damage occurs during use, thereby reducing the service life of the compacted steel wire rope

Abstract

The invention relates to a rope core of a compacted steel wire rope, which is applied to the technical field of processing of the steel wire rope. The invention is characterized in that the weight portions of the compositions of the special material of the rope core are as follows: 69 portions to 71 portions of polypropylene, 14 portions to 16 portions of high density polyethylene, 4 portions to 6 portions of polyolefin elastomer, 4 portions to 6 portions of ethylene propylene diene rubber, 3 portions to 5 portions of nylon 6, 0.4 portion to 0.6 portion of ultraviolet absorbent and 0.4 portion to 0.6 portion of antioxidant. The compact steel wire rope has the effects that the fiber of the steel wire core has no shatter and fracture. The steel wire core has the advantages of shock resistance, extrusion resistance, and ageing resistance. By changing the manufacturing materials and manufacturing technique of the rope core of the compacted steel wire rope, the shock resistance of the rope core is improved, the rope core has good supporting effect in the using process of the compacted steel wire rope and the service life of the compacted steel wire rope is prolonged.

Description

technical field [0001] The invention belongs to the technical field of steel wire rope manufacture, and particularly relates to a rope core of a steel wire rope, which is a special rope core for a compacted steel wire rope, that is, an impact-resistant polypropylene rope core. Background technique [0002] The rope core of the steel wire rope is in the center of the steel wire rope, and the rope core plays a role in supporting and storing grease in the steel wire rope. The fiber core of the steel wire rope is generally processed from sisal or jute. This kind of fiber rope core cannot adapt to the rope core usage requirements of the compacted steel wire rope. [0003] At present, the production process of compacted steel wire rope is: twisting the steel wire rope according to the conventional production process, and then forming the steel wire rope through pressure processing (usually by forging method), that is, the steel wire rope is deformed under the action of the impact...
