Abstract
The invention discloses a plastic filled steel wire rope for an electric shovel and a manufacture method for the same; the structure of the plastic filled steel wire rope is 8K*K55SWS+IWRS; a structure of a center strand of the steel wire rope is a 8*7 structure steel wire rope; the structures of a center strand core and the outer layer strand of the steel wire rope are both 1*55SWS; the center strand core and the outer layer strand are obtained by one-time twisting; and after the molding of the steel wire rope through twisting, compaction and plastic coating processing are performed on the steel wire rope. After compaction and plastic coating processing, the wearing resistance and antifatigue performance of the steel wire rope are dramatically improved, which reduce the wearing resistance on an electric shovel lifting winding drum so as to prolong the service life.
Description
Technical field
The present invention relates to a kind of power shovel plastic-filled steel wire rope and manufacture method thereof, belong to metallic article processing technique field.
Background technology
Current domestic Wire Rope Production producer has been provided with producing the ability of power shovel steel wire rope, the knot of power shovel steel wire rope
Structure is usually 6 × 36WS+IWRC, diameter more than 58mm to be reached, and steel wire rope group stock steel wire includes 36,41,49 etc., steel wire
Rope group stock also by 6 strands to 8 bursts of transition, define 8 × 36WS+IWRC with large diameter wire rope as representative, 8 × 41WS+IWRC,
8 × 49SWS+IWRC big structure large-specification wire rope.The most domestic being the most only merely produces bright finish or zinc-plated thick straight
The power shovel steel wire rope in footpath, can produce that to fill out the power shovel steel wire rope technology of plastotype the most immature, the anti-wear performance of steel wire rope and resistance to
Fatigue behaviour is low, and service life is short.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of power shovel plastic-filled steel wire rope and manufacture thereof
The technical problem that method, solution power shovel steel wire rope anti-wear performance and fatigue performance are low, improves service life of steel wire rope.
A kind of power shovel plastic-filled steel wire rope of the present invention, structure is 8K × K55SWS+IWRC, and it is by a central strand and eight
Root outer layer strand is constituted, in surface contact structure;
Described central strand structure is 8 × 7, is made up of a central strand core and eight silent partners, in surface contact structure, and central strand core
Structure is 1+9+9+9/9+18, is made up of 55 steel wire primary twistings, and silent partners structure is 1+6, seven steel wires twist with the fingers
System is constituted;
Described outer layer strand structure is 1+9+9+9/9+18, is made up of 55 steel wire primary twistings, the contact knot in face
Structure.
The manufacture method of the power shovel plastic-filled steel wire rope of the present invention, including implementing step as follows:
(1) first twisting central strand, again through roller compaction after central strand twisting molding, compacting rate is 8-15%, and making central strand is face
Contact structures state, after carry out plastic-coated process again, plastic layer is 1-3mm;
(2) then twisting outer layer strand, then through roller compaction, compacting rate is 6-12%, makes outer layer strand be changed in face by contact structure
Contact structures state, after carry out plastic-coated process again, plastic layer is 1-3mm;
(3) last twisting finished product steel wire rope, is twisted with the fingers a central strand by eight outer layer strand bags and constitutes, and finished steel cord is again through roll-in
Real, compacting rate is 6-12%, carries out plastic-coated process the most again, and plastic layer is 1-3mm.
Beneficial effects of the present invention:
Due to steel wire rope central strand, outer layer strand and steel wire rope all through roller compaction and carry out plastic-coated process, steel wire rope silk and silk it
Between, between stock and stock in surface contact structure state, steel cord structure is more tight, and steel wire rope anti-wear performance and fatigue performance show
Writing and improve, bearing capacity is big, it is possible to alleviates the abrasion to power shovel hoisting drum, thus improves service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention a kind of power shovel plastic-filled steel wire rope.
In figure: 1 central strand, 2 outer layer strand, 11 central strand cores, 12 silent partners.
Detailed description of the invention
Below in conjunction with accompanying drawing, one power shovel plastic-filled steel wire rope of the present invention and manufacture method thereof are described in further detail:
In Fig. 1: a kind of power shovel plastic-filled steel wire rope of the present invention, structure is 8K × K55SWS+IWRC, and it is by a central strand 1
Constitute, in surface contact structure with eight outer layer strand 2;
Described central strand 1 structure is 8 × 7, is made up of a central strand core 11 and eight silent partners 12, in surface contact structure, in
Heart stock core 11 structure is 1+9+9+9/9+18, is made up of 55 steel wire primary twistings, and silent partners 12 structure is 1+6, by
Seven steel wire twistings are constituted;
Described outer layer strand 2 structure is 1+9+9+9/9+18, is made up of 55 steel wire primary twistings, the contact knot in face
Structure.
The manufacture method of the power shovel plastic-filled steel wire rope of the present invention, including implementing step as follows:
(1) first twisting central strand 1, again through roller compaction after central strand 1 twisting molding, compacting rate is 8-15%, makes central strand 1
In surface contact structure state, after carry out plastic-coated process again, plastic layer is 1-3mm;
(2) then twisting outer layer strand 2, then through roller compaction, compacting rate is 6-12%, make outer layer strand 2 by contact structure change in
Surface contact structure state, after carry out plastic-coated process again, plastic layer is 1-3mm;
(3) last twisting finished product steel wire rope, is wrapped a piece central strand 1 of sth. made by twisting and constitutes by eight outer layer strand 2, and finished steel cord is again through roller
Compacting, compacting rate is 6-12%, carries out plastic-coated process the most again, and plastic layer is 1-3mm.
Due to the fact that steel wire rope central strand, outer layer strand and steel wire rope are all through roller compaction and carry out plastic-coated process, steel wire
In surface contact structure state between rope silk and silk, between stock and stock, steel cord structure is more tight, steel wire rope anti-wear performance and resistance to
Fatigue behaviour significantly improves, and bearing capacity is big, it is possible to alleviates the abrasion to power shovel hoisting drum, thus improves service life.
