Abstract
A kind of triangular strand wire rope manufacture method, steel cord structure is 6V × 37S, is made up of six roots of sensation triangle strand and a hemp core or metal-cored twisting, the lower strands of first twisting strand, then by strands and outer layer strand in series connection unit primary twisting, finally carry out closing rope on rope-forming machine.The present invention solves triangular strand wire rope stress, and greatly and stock silk compactness is poor and stock turns over the mass defects such as rib, decreases the fatigue breaking of steel wire rope, improves product twisting quality in kind and service life of steel wire rope.
Description
Technical field
The present invention relates to a kind of triangular strand wire rope manufacture method, belong to metallic article processing technique field.
Background technology
It is poor to there is stock silk compactness in existing triangular strand wire rope, and the stress of stock and steel wire rope is relatively big, and stock turns over rib, steel wire rope
The mass defects such as Twisting quality is unstable, in use there will be steel wire rope fracture of wire in early days, cause the use of this steel wire rope
Life-span is shorter.Therefore, we are by the optimal design to the internal layer pitch of triangular strand wire rope strand with outer layer pitch, the outer layer of stock
Pitch and the optimal design of wire rope lay pitch, in process of production, control strand wire ectonexine pitch and the effective of the lay pitch,
Effective control to the rope lay pitch, to strand wire and effective control of rope stress, solves that triangular strand wire rope stress is big and stock
Silk compactness difference and stock turn over the mass defects such as rib, reduce the fatigue breaking of steel wire rope, improve the service life of steel wire rope.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of triangular strand wire rope manufacture method, logical
Cross the optimal design of the internal layer pitch to strand wire and outer layer pitch, the outer layer pitch of stock and most preferably setting of wire rope lay pitch
Meter, thus improve triangular strand wire rope twisting quality in kind, improve the service life of steel wire rope.
The technical scheme is that, the lower strands of first twisting strand, then by strands in series connection unit primary twisting and
Outer layer strand, finally closes rope with strand with hemp core or metal-cored carrying out on rope-forming machine.
The triangular strand wire rope of the present invention, steel wire rope allusion quotation shape structure is 6V × 37S, by 6 triangle strands and a hemp core
Or metal-cored twisting is constituted.
The manufacture method of the triangular strand wire rope of the present invention, including implementing step as follows:
(1) strand manufacture
The structure of strand is/1 × 7+3/+12+15, and strand twisting process parameter is: the lower strands of first twisting 1 × 7, roller end away from for
15～24 times of strand diameter, the press-bending degree of depth is 1.1～1.3 times of strand diameter, then once twisting/1 on series connection unit
The middle strands of × 7+3/+12+15 and outer layer strand, internal layer pitch ratio little 8 to the 18mm of outer layer pitch of stock, design parameter is with steel wire rope
Specification size and quantification.
During strand twisting, being adjusted by each I-shaped hub brake rope consistent, steel wire must not occur before three fork plate or trident roller
Playing curved phenomenon, three fork plate or trident roller must compress, and fuselage cable-through hole, mother-in-law's compass roller grooving must not hinder line, stock smooth surface, stock
Oil spout, strand checks stock stress after outputing 100 meters, later every 1 strand pulls out 4 meters, checks in its natural state and play torsion, and all stocks are equal
Control within-180 °～-360 °, control stock stress the most on request.
(2) rope is become to manufacture
Twisting process parameter: wire rope lay pitch is 7.0～7.3 times of rope footpath, predeformation roller spacing is the 0.8～0.85 of the rope lay pitch
Times, the predeformation press-bending degree of depth is 1.0～1.2 times of rope footpath, and Forming die specification is identical with rope footpath, ensures that each stock is twisted with the fingers during twisting
Even tension processed, carries out brokenly strength to stock and stands up, and per share pitch is basically identical, stock pitch ratio big 4 to the 8mm of the rope lay pitch, design parameter
With the specification size of steel wire rope and quantification.Steel wire rope must not turn over rib, crack, flake；With driving by steel wire rope during twisting
Sling more than 4 meters, check that steel wire rope beats torsion situation, within steel cable stress 0 °～-360 °.
The present invention solves triangular strand wire rope stress, and greatly and stock silk compactness is poor and stock turns over the mass defects such as rib, decreases
The fatigue breaking of steel wire rope, improves the service life of steel wire rope.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail:
As a example by producing 6V × 37S+FC-36mm steel wire rope:
This steel wire rope is made up of six roots of sensation triangle strand and a hemp core twisting, the lower strands of first twisting strand, the most again with series connection
Strands and outer layer strand in unit primary twisting, finally carry out closing rope with strand and hemp core on rope-forming machine.
The manufacture method of the triangular strand wire rope of the present invention, including implementing step as follows:
(1) strand manufacture
The structure of strand is/1 × 7+3/+12+15, and strand twisting process parameter is: the lower strands of first twisting 1 × 7, roller end away from for
20 times of strand diameter, the press-bending degree of depth is 1.2 times of strand diameter, then once twisting/1 × 7+3/+12+ on series connection unit
The middle strands of 15 and outer layer strand, the internal layer pitch of stock is 248mm, and outer layer pitch is 258mm.
During strand twisting, being adjusted by each I-shaped hub brake rope consistent, steel wire must not occur before three fork plate or trident roller
Playing curved phenomenon, three fork plate or trident roller must compress, and fuselage cable-through hole, mother-in-law's compass roller grooving must not hinder line, stock smooth surface, stock
Oil spout, strand checks after outputing 100 meters plays torsion, pulls out 4 meters every 1 strand later, checks stress in its natural state, and all stocks are equal
Control within-270 °, control stock stress the most on request；
(2) rope is become to manufacture
Twisting process parameter: wire rope lay pitch is 7.06 times of rope footpath, and predeformation roller spacing is the 215mm of the rope lay pitch, gives deformation
The press-bending degree of depth is 1.1 times of rope footpath, and Forming die specification is identical with rope footpath, ensures that each stock stranding tension is uniform, enter stock in twisting
The broken strength of row is stood up, and per share pitch is basically identical, and the stock pitch ratio big 4mm of the rope lay pitch, steel wire rope must not turn over rib, crack, flake；Twisting
During with driving steel wire rope is sling more than 4 meters, check steel wire rope stress situation, within steel cable stress-90 °.
