Embodiment Construction

[0012] The invention provides a method for manufacturing a special steel wire rope for electrified railways. During the production process, the method for manufacturing the steel wire rope includes the following steps:

[0013] A. Firstly produce 1X37 single strand, its structure is 1+6+12+18, the steps are:

[0014] a. First use 1 steel wire with a wire diameter of 0.62-0.63 mm as the core, use 6 steel wires with a wire diameter of 0.62-0.63 mm as the outsourcing strand, and use 200-type 6-disc twisting equipment to make 1X7 strands with a diameter of 1.88 mm wire rope;

[0015] b. Use the 1X7 steel wire rope with a diameter of 1.88 mm as the core, use 12 steel wires with a diameter of 0.60-0.61 mm as the outer strands, and use the 200-type 12-disc twisting equipment to make a 1X19 wire rope with a diameter of 3.09 mm. wire rope;

[0016] c. Use the 1X19 steel wire rope with a diameter of 3.09 mm as the core, use 18 steel wires with a diameter of 0.60-0.61 mm as the outer s...

Abstract

The invention discloses a method for making a special steel wire rope for electrified railways, which comprises the following steps: A. First make a single strand of 1X37, the structure is 1+6+12+18, first use 0.62-0.63mm steel wire, 200 type 6 coils To make a 1X7 steel wire rope with a strand diameter of 1.88mm, use 0.60-0.61mm steel wire 200 type 12 coils to make a 1X19 steel wire rope with a strand diameter of 3.09mm, and then use 0.60-0.61mm steel wire 200 type 18 coils to make 1X37 with a strand diameter of 4.30 mm steel wire rope; B, make the rope core again, use 7 single strands of 1X37 strand diameter 4.30mm to synthesize a rope core of 7X37 diameter 12.9mm; C, make outsourcing strands again, the outsourcing strands are the above single strands; D, close the rope . The steel wire rope produced by the manufacturing method of the invention has a small rope core, a large lay distance of the combined rope, and the weight is reduced under the condition that the length remains constant, thereby saving materials.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a method for manufacturing a special steel wire rope for electrified railways. Background technique [0002] The normal method of special steel wire rope for electrified railway is to make the core first, the structure is 7X37 steel wire rope, the core diameter is 13.2mm, the single strand is 1X37 steel wire rope, the structure is 1+6+12+18; the single strand method is to use 0.62 -0.63mm steel wire, 200 type 6 reels to make 1X7 strand diameter 1.89-1.90mm steel wire rope, then use 200 type 12 reels to make 1X19, strand diameter 3.15-3.16mm steel wire rope, then use 200 type 18 reels to make 1X37 , a steel wire rope with a strand diameter of 4.41-4.42mm; use 7 single strands of 1X37 strand diameter of 4.41-4.42mm to synthesize a 7X37 rope core with a diameter of 13.2 mm; the single strand of the outsourcing strand is also 1X37, and the structure is 1+6+12+18. In order to ...
