Abstract

The invention relates to a production method of a large-diameter triangular strand steel wire rope. In the method, a core rolling machine is used to roll round strands into triangular strand cores; strands of steel wire ropes are produced through a series strand rope unit; the number of steel wire layers outside the triangular strand core is 2 Layer or 3 layers, the total number of steel wires is in the range of 39-81, excluding the number of core steel wires; and then made into steel wire ropes through a rope forming machine. The series-connected strand-rope unit is a three-series-connected strand-rope unit or a four-series-connected strand-rope unit; the three-series-connected strand-rope unit is used to produce strands with two layers of steel wire outside the core; the four-series-connected strand-rope unit is used to produce The outside of the strand core is a strand of 3 layers of steel wire. In this method, round strands are rolled into triangular strand cores, the size of strand cores and the number of outer steel wire ropes are reasonably selected, and qualified large-diameter triangular strands are produced through continuous production of a series strand rope unit. The process is reasonable and the quality meets the requirements. Require.

Description

A kind of production method of large-diameter triangular strand wire rope

Technical field

The present invention relates to a kind of production method of major diameter steel wire rope.

Background technology

The production method of triangular strand wire rope thigh is to use special-purpose strander to produce section configuration to be leg-of-mutton strand, on rope-forming machine, to push through special-purpose rotational forming device then, is twisted into steel wire rope.The triangular strand wire rope diameter that existing structure is produced can only be below 58mm, and the above triangular strand wire rope one of 60mm is not have suitable structure, and the 2nd, equipment does not possess production capacity.

Utilize existing structure to produce large-diameter triangular strand wire rope; Just simply steel wire diameter in the thigh is amplified, this disadvantage that can bring is: steel wire diameter is too thick in strand, and is not easy to operate during production; And mainly be that safety assurance ability in use reduces; The flexibility variation, the steel wire rope fatigue performance reduces, and service life is short.

Summary of the invention

The production method that the purpose of this invention is to provide a kind of large-diameter triangular strand wire rope; This method is rolled into triangle thigh core through justifying thigh; Choose reasonable thigh core size and cover wire rope radical through series connection strand unit one line quantity-produced mode, are produced qualified large-diameter triangular strand; Technology is reasonable, and quality meets the demands.

The present invention realizes through following technical scheme:

A kind of production method of large-diameter triangular strand wire rope, this method comprises the steps:

1) adopts and to roll the core machine and will justify thigh and be rolled into triangle thigh core;

2) pass through the thigh that series connection strand unit is produced steel wire rope; The outside steel wire number of plies of triangle thigh core is 2 layers or 3 layers, and the total radical of steel wire does not comprise a strand core wire radical in the 39-81 scope;

3) process steel wire rope through rope-forming machine again.

Described series connection strand unit is three string series connection strand units or four string series connection strand units; It is the thigh of 2 layers of steel wire that three string series connection strand units are used for producing a burst core outside; It is the thigh of 3 layers of steel wire that four string series connection strand units are used for producing a burst core outside.

The I-beam wheel number of described series connection strand unit is 57-121.

Described rolling is equipped with 2-5 group roll on the core machine, roll is contained on the rotary turnplate; Every group of roll comprises 2 or 3 active rolls, and roll pass is a triangle.

The rotating speed of described rotary turnplate is identical with the pitch dish rotating speed of series connection strand unit.

Compared with prior art, the invention has the beneficial effects as follows: adopt this method can produce the triangular strand wire rope that maximum gauge can reach 100mm, substitute the major diameter round-strand rope, improved the product use and received the order, satisfy user's instructions for use.

The specific embodiment

4) see Fig. 4-1, Fig. 4-2, adopt and to roll the core machine and will justify thigh and be rolled into triangle thigh core;

2) see Fig. 1-1, Fig. 1-2, the outside steel wire number of plies of triangle thigh core is 2 layers or 3 layers, and the total radical of steel wire does not comprise a strand core wire radical in the 39-81 scope; Produce the thigh of steel wire rope through series connection strand unit; Community of stock rope unit is three string series connection strand units or four string series connection strand units; It is the thigh of 2 layers of steel wire that three string series connection strand units are used for producing a burst core outside; Four string series connection strand units are used for producing the thigh (see figure 3) that burst core outside is 3 layers of steel wire.The number of the I-beam wheel of series connection strand unit is 57-121.

3) process steel wire rope through rope-forming machine again, the steel wire rope sectional drawing is shown in Fig. 2-1, Fig. 2-2.

Roll 2-5 group roll is installed on the core machine, roll is contained on the rotary turnplate; Every group of roll comprises 2 or 3 active rolls, and roll pass is a triangle.The rotating speed of rotary turnplate is identical with the pitch dish rotating speed of series connection strand unit.
