Roller-stretching-process dual-Y type rolling mill for compacted-strand steel wire rope

Abstract

The invention discloses a roller-stretching-process dual-Y type rolling mill for a compacted-strand steel wire rope. The roller-stretching-process dual-Y type rolling mill comprises draw bars (1), a bottom plate (2) and two roller units (3), wherein each roller unit (3) comprises a worm and gear box assembly (4), a mounting head (5), a fork head (6), a roller core (7), a roller sheet (8), a tension spring (16) and a stand (10); each worm and gear box assembly is arranged on the corresponding stand; worms are arranged on worm gear shafts; the inner circle of each mounting head is connected with the corresponding worm gear shaft, and the outer circle of each mounting head is connected with the corresponding stand; one end of each fork head is arranged on the corresponding mounting head, and the other end of each fork head is connected with the corresponding roller core; each roller sheet is arranged on the corresponding roller core; one end of each tension spring is arranged on the corresponding fork head, and the other end of each tension spring is arranged on the corresponding stand; the two roller units are arranged on the bottom plate; and the draw rods are connected with the two roller units. The roller-stretching-process dual-Y type rolling mill disclosed by the invention has the advantages of compact design, preciseness in scale division, convenience in adjustment, high product glossiness and long service life of the rollers.

Description

technical field [0001] The invention relates to a double Y-shaped rolling mill for compacting strand steel wire ropes by roller pulling method. Background technique [0002] Steel wire rope products have a history of 100 years. With the process of industrialization, there are further requirements for steel wire rope products, such as wire rope compaction and packing. [0003] In many foreign industries, compacted strand steel wire ropes are preferred, and compacted strand steel wire ropes are gradually widely used in many industries in my country, such as shaft hoisting, shaft balancing ropes, excavators (electric shovel winches), rotary drilling rigs, port handling and building towers cranes etc. [0004] Comparison of various production methods of compacted strand steel wire rope: The production methods of compacted strand steel wire rope can be roughly divided into: die drawing, roller drawing, rolling and forging and other methods. [0005] (1) Die-drawing method: There...

AI Technical Summary

Problems solved by technology

[0005] (1) Die-drawing method: There are many mold-passing processes and large resistance, sometimes the tractor cannot drive

The mold wears quickly, especially during the production process, the mold hole becomes larger or damaged, which causes great difficulties in production

[0006] (2) Rolling and forging method: it is often necessary to carry out the second rolling after forming a strand, and the production efficiency is low
