Description
Technical field
The utility model belongs to steel wire rope manufacturing technology field, particularly a kind of two compacting steel wire ropes that adopt the die drawing method, forge the method explained hereafter.
Background technology
Steel wire rope is used very extensive in modern industry, and market is also more and more higher to the steel wire rope quality requirement simultaneously.Require steel wire rope to have the rupture pull force height; From heavy and light, good toughness, structural stretch is less; Good shock resistance and anti-squeezing are ruined performance; Long service life etc.
At present, the steel wire rope of domestic production is mainly based on regular lay stranding steel wire rope, and Wire Rope Production higher for technology content, that structure is complicated is less, especially compacting class steel wire rope.Compacting class steel wire rope origin early, our company began to develop compacting class steel wire rope so far from 1999, the production history in existing nearly ten years, through continuous technological transformation and technical research, develop the compacting class steel wire rope of more than ten kind of different structure successively, wherein four products have obtained utility model patent.As a kind of all fronts contact compacting steel wire rope, Granted publication number: CN2730915Y; With the compaction-strand steel wire rope that the method that forges is produced, Granted publication number: CN2683687Y; The compacting plastic-filled steel wire rope, Granted publication number: CN2808987Y; Suction is dragged for oil and is used steel wire rope, Granted publication number: CN2402868Y.The kind of existing compacting steel wire rope is few; The density metal of ordinary steel rope is low; Whole rope rupture pull force value is little; Service life is shorter; Shock resistance and anti-squeeze that to ruin performance low etc. can not satisfy the modern industry development to the steel wire rope requirement.
The utility model content
The purpose of this utility model provides a kind of pair of compacting steel wire rope, changes steel cord structure, and thigh and rope all pass through compaction process processing.Line contact changing into the face between the steel wire that makes contacts, and improves the density metal of strand, improves the metal end face rate of steel wire rope, improves the whole rupture pull force of restricting, and has prolonged the service life of steel wire rope.
The utility model is that the technical scheme that its technical purpose of realization is taked is: two compacting steel wire ropes, be twisted into by 6 thighs and wire rope core, wire rope core is in the middle of 6 thighs, thigh is made up of core wire and cover wire, it is characterized in that: thigh is the compacting thigh, promptly thigh has a core wire, and the cross section of core wire is a regular polygon, and the quantity on regular polygon limit is 3～9; It is that fan-shaped, fan-shaped outside is a circular arc that thigh has 3～9 cover wires, the cross section of every cover wire, and fan-shaped inner edge is a linear.Limit of the fan-shaped inner edge and the regular polygon of core wire is adjacent to, and face contacts between cover wire inner edge and the core wire.
Described core wire cross section is a regular hexagon, and thigh has 6 cover wires.
Wire rope core adopts modified polypropylene fiber, and the cross section of modified polypropylene fiber is a hexagon, and the shape on each bar limit is cave inward circular-arc, and promptly modified polypropylene fiber is full of the hexagon space that 6 thighs surround.
Every adjacent junction, both sides of described core wire cross section is circular-arc; The junction on per two limits that described cover wire cross section is fan-shaped is a circular arc.
The steel wire rope key technology is to realize the thigh compacting and the compaction process of restricting, and the process technology scheme of taking is: unsteady compacting frock, the interior dress fixed die of design voluntarily adopted in burst compacting, and the twisting of thigh and compacting process are once finished on sth. made by twisting strand equipment; Steel wire rope is the twisting moulding on crank closer, after forging through the equipment of swaging, to realize the production of two compacting steel wire ropes again.
The technological process of production: raw material-heat treatment-wire drawing-sth. made by twisting thigh-thigh compacting-close and restrict-forge
In the new technological flow that adopts:
1) wire drawing: adopt scale or multiple length blanking, steel wire does not have the welding joint in scale or the multiple length.
2) twisting with the fingers thigh and burst compacting once finishes on sth. made by twisting strand equipment.
The beneficial effects of the utility model are:
The two compacting steel wire ropes of the utility model are compared with ordinary steel rope and are mainly contained following advantage:
1, two compacting steel wire rope group rope strands are compacting-type, and face contact between the group strand steel wire realizes two consolidated structure, the density metal height of steel wire rope;
2, whole rope rupture pull force value height;
3, two compacting steel wire rope surface metal areas increase, and have good abrasion resistance, have prolonged the service life of steel wire rope;
4, have good shock resistance and the anti-crowded performance of ruining;
5, two compacting steel cord structures are tight, stable, and structural stretch is less.
