Description

Compaction strand rotary die drawing device

Technical Field

The invention relates to a compaction strand rotary die drawing device, and belongs to the technical field of metal product processing equipment.

Background

In the production process of the compacted strand steel wire rope, because steel wires in strands are in a surface contact state, generally, an outer layer steel wire and a center steel wire gradually pass through a fixed die core hole in the production process, and a stranding machine is started to draw after heads are hung. The structural design of the die drawing apparatus therefore determines the useful life of the die core and the surface quality of the die drawn strand. The original production of twisting the strand with the compaction strand of company all adopts the fixed die to draw the mode, and the surface of strand receives the mold core hole influence easily to cause outer steel wire to strain, and the ovality is out of tolerance. And because the requirement of the die drawing strand on the traction force is large so as to ensure enough traction force, a large-specification stranding machine is often selected for production, and great waste is caused to equipment resources. Therefore, it is an urgent matter to solve the die-drawing problem when the compacted strand of the steel wire rope is twisted.

Disclosure of Invention

The invention aims to solve the technical problems of simple design structure, flexible operation, reliable operation, low cost, strong applicability and long service life and can meet the die drawing requirements of a stranding machine in the production process of various compacted strand steel wire ropes of companies.

In order to solve the technical problems, the invention adopts the following technical scheme:

a rotary die drawing device for compacted strands comprises a motor turbine worm reducer, an output shaft, a small chain wheel, a chain, a large chain wheel, an upper cooling pipe joint, a lower cooling pipe joint, a bearing seat, an end cover, a screw, a bearing A, a sealing ring, a mandrel, a die sleeve, a rotary die core, a jackscrew, a trapezoidal screw, a compression end cover, a bearing, a die seat and a bearing B, wherein the output shaft is arranged on one side below the motor turbine worm reducer, the small chain wheel is arranged on one side of the output shaft, the small chain wheel is connected with the large chain wheel through the chain, and the large chain wheel and the die sleeve are fixed through a bolt; the die sleeve and the mandrel are fixed on the bearing block through a bearing A and a bearing B; a sealing ring is arranged in the end cover and is fastened by a screw, and the rotary mold core is tightly propped against the end face of the mold sleeve by a jackscrew; the bearing and the pressing end cover are used for connecting and fixing the trapezoidal screw rod with the die holder; a bearing seat is arranged above the trapezoidal screw rod; and an upper cooling pipe joint and a lower cooling pipe joint are arranged below the die sleeve.

The beneficial effect of adopting above-mentioned technical scheme is:

the invention has the characteristics of simple operation, reliable action, low cost, adjustable mold core rotation speed, long service life and the like, reduces the defects that the strand surface of the compacted strand steel wire rope is damaged by steel wire pulling, the ovality is over poor and the like in the strand twisting process, and solves the problems of poor mold core cooling effect and short service life of the strand in the mold pulling process. The problem of excessive traction force requirement in the production process reasonably utilizes equipment resources and improves the quality of the compacted strand steel wire rope product.
