Abstract
A kind of multi-strand wire rope manufacturing method, in internal layer rope twisting, predeformation is not carried out to rope strand, 45-50% predeformation is carried out during outer layer strand twisting to stock, make outer layer strands energetically, meet the balance with internal layer rope, during twisting wire rope, internal layer rope is carried out energetically, the number of turns energetically is 45 circles, with the progress of production, it is gradually distributed in the range of entire rope capacity energetically, it is more energetically, steel wire rope enters the state of ectonexine lay pitch balance soon after file leader comes out, it is finally reached the balance of steel wire rope ectonexine stock, roller compaction finally is carried out to the steel wire rope of twisting, compression ratio is 14%.Fragile strength is not allowed during steel wire rope use of the present invention, service life of steel wire rope is high.
Description
Technical field
The present invention relates to multi-strand wire rope manufacturing methods, belong to metal cord processing technique field.
Background technology
During existing multi-strand wire rope use, when being run on pulley, steel wire rope rotates while running, each
In a cycle, the number of turns that steel wire rope rotates during up and down is different, such as：3 circles are had rotated when on steel wire rope, when lower only
2 circle back, does not have a cycle that steel wire rope is resulted in have accumulated a circle above, leads to steel wire rope overlying one end ectonexine rope
It is separated from each other, internal layer rope stress is elongated, and the extra length of wire rope core is easy for protrusion outer layer strand during unloading, steel wire rope occurs and break strength showing
As quality accident occurs.For the steel wire rope since rupture pull force requires height, use environment narrow space, bending angle are more sharp,
Production difficulty is very big.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of multi-strand wire rope manufacturing method, solution
The technical issues of strength is certainly easily broken during steel wire rope use, improves service life of steel wire rope.
The multi-strand wire rope production control of the present invention is quite important, and control purpose is that wire rope core not allowed to break strength, and control will
Point is as follows：
（1）Without predeformation when multi-strand wire rope produces internal layer rope, cause internal layer rope strength very big in this way, produce outer layer
45-50% predeformation is carried out during stock, it is therefore an objective to carry out balance with internal layer rope, be finally reached the mesh of ectonexine balance
's；
（2）It is non-to the processing of internal layer rope when particularly closing internal layer tail of rope portion in order to ensure that internal layer rope strength is not broken
It is often important, it is ensured that the tension of rope strand, it is ensured that wire rope core by broken strength, is not tied up and has in place, ensure internal layer rope not by broken strength；It is interior
When layer rope production is completed to produce other one if necessary, wire rope core and another twist direction are preferably twist-on-twist, are otherwise easy to brokenly
Strength；
（3）In twisting steel wire rope, internal layer rope is carried out energetically, the number of turns energetically is enclosed for 4-5, this strength is with production
It carries out, is gradually distributed in the range of entire rope capacity, it is more energetically not only in one section of beginning, after file leader comes out
Steel wire rope enters the state of ectonexine lay pitch balance soon.It closes and restricts to last, it is necessary to assure wire rope core is wrapped in Loosen up wire wheel
On the number of turns it is enough, to provide enough tension, ensure that the strength on wire rope core is not broken, have to ensure steel wire rope in tail of rope
Not by broken strength, particularly it will ensure that steel wire rope strength is not broken during tying up, generation draws and turns one's head.
（4）Roller compaction, compression ratio 14% finally are carried out to the steel wire rope of twisting.
Beneficial effects of the present invention：
It solves the technical issues of strength is easily broken in steel wire rope use in the process, improves service life of steel wire rope.
Specific embodiment
A kind of multi-strand wire rope manufacturing method of the present invention is described in further detail below：The multilayer strand steel of the present invention
Cord manufacturing method, including step is implemented as follows：
（1）Internal layer rope twisting does not carry out predeformation during production to rope strand, and internal layer rope will be tied up securely in production, it is ensured that interior
Layer rope by broken strength, does not ensure rope strand tension；
（2）Outer layer strand twisting carries out 45-50% predeformation during production, makes outer layer strands energetically, meets and internal layer rope
Balance；
（3）Twisting wire rope carries out twistings by an internal layer rope and more outer layer strands, during twisting, need by internal layer rope into
Row energetically, for 4-5 enclose, and with the progress of production, is gradually distributed in the range of entire rope capacity energetically by the number of turns energetically, on
Strength is more, and steel wire rope enters the state of ectonexine lay pitch balance soon after file leader comes out, and is finally reached steel wire rope ectonexine stock
Balance, close rope to last, ensure that the number of turns that internal layer rope is wrapped on Loosen up wire wheel is enough, to provide enough
Power ensures that the strength on internal layer rope is not broken, and has to ensure steel wire rope not by broken strength in tail of rope, particularly tie up, in generation, does
It draws and will ensure that steel wire rope strength is not broken during turning one's head；
（4）Roller compaction, compression ratio 14% finally are carried out to the steel wire rope of twisting.
Claims (1)
1. a kind of multi-strand wire rope manufacturing method, it is characterised in that including step is implemented as follows：
（1）Internal layer rope twisting does not carry out predeformation during production to rope strand, and internal layer rope will be tied up securely in production, it is ensured that internal layer rope
Not by broken strength, ensure rope strand tension；
（2）Outer layer strand twisting carries out 45-50% predeformation during production, makes outer layer strands energetically, meets the torque with internal layer rope
Balance；
（3）Twisting wire rope carries out twistings by an internal layer rope and more outer layer strands, during twisting, needs to carry out in internal layer rope
Strength, the number of turns energetically enclose for 4-5, with the progress of production, are gradually distributed in the range of entire rope capacity, get over energetically energetically
More, steel wire rope enters the state of ectonexine lay pitch balance soon after file leader comes out, and is finally reached the torsion of steel wire rope ectonexine stock
Square balances, and closes rope to last, ensures that the number of turns that internal layer rope is wrapped on Loosen up wire wheel is enough, to provide enough tension,
Ensure that the strength on internal layer rope is not broken, have to ensure steel wire rope not by broken strength in tail of rope, tie up, in generation, draws and
It will ensure that steel wire rope strength is not broken during turning one's head；
（4）Roller compaction, compression ratio 14% finally are carried out to the steel wire rope of twisting.
