Abstract
A steel wire rope of a cableway with the diameter of 35mm is produced, the steel wire rope is 6 multiplied by 19S + IWS, firstly, a metal strand core with the structural specification of 1 multiplied by 7-phi 5-Z is produced, then, the metal strand core is coated with plastic to form a plastic rod core with the diameter of 10.20mm, then, the plastic rod core is coated with plastic, the outer layer of plastic is soft, and the diameter of the whole strand core after the second plastic coating is 16.20 mm; finally, heating and softening the plastic by adopting an intermediate frequency furnace after the strand core is arranged on the machine body to produce the cableway steel wire rope. The steel wire rope has the advantages of good forming effect, large breaking force and long service life.
Description
Technical Field
The invention relates to a production process of a cableway steel wire rope with the diameter of 35mm, and belongs to the technical field of metal product processing.
Background
The invention relates to a steel wire rope for a manned cableway, which usually adopts PPC as a rope core, the rope core is easy to rot and break when the steel wire rope with the structure is used, and the service life of the steel wire rope is shortened. The plastic-coated electric shovel rope, the harbor machine rope and the core plastic-coated application are wide, and the plastic-coated electric shovel rope and the harbor machine rope are successfully used in various fields. The invention is beneficial to controlling the diameter of the manned cableway rope, filling the space between strands with plastic, increasing the contact area of the steel wire rope, improving the breaking tension of the cableway rope and prolonging the service life of the steel wire rope.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a production process of a cableway steel wire rope with the diameter of 35mm, and solves the technical problem of short service life of the cableway steel wire rope.
The technical scheme includes that in the production of the steel wire rope, the metal strand core is coated with plastic twice, and the whole composite strand core is formed by compounding the metal strand core and the plastic twice.
The implementation steps of the invention are as follows:
(1) producing a metal strand core with the structural specification of 1 multiplied by 7-phi 5-Z, and actually measuring the diameter: 5.0 mm;
(2) plastic coating is carried out on the metal strand core with the diameter of phi 5.0 mm, and the plastic coating is carried out to form a plastic rod core with the diameter of 10.20 mm; the hardness of the inner layer plastic is higher, and the proportion of the plastic in the whole strand core is 75 percent;
(3) then, performing second plastic coating on the plastic rod core with the diameter of 10.20mm, wherein the plastic on the outer layer is soft, the proportion of the plastic in the whole strand core is 25 percent, and the actual measurement diameter of the whole strand core after the second plastic coating is 16.20 mm;
(4) finally, a composite rope core with the diameter of 16.20mm is used, and the plastic is heated and softened by an intermediate frequency furnace behind the machine body to produce the 6 multiplied by 19S + IWS-phi 35-ZZ-1960MPa cableway steel wire rope.
The cableway steel wire rope has good forming effect and balanced rope diameter control, the breaking tension of the whole rope reaches 869KN, the minimum breaking tension of 6 multiplied by 19S + FC-phi 35-ZZ-1960MPa is 792.33KN, and the breaking tension of the cableway rope produced by adopting the special composite rope core is improved by about 10 percent compared with the synthetic fiber core with the same specification and the same strength.
