Description
Technical field
The present invention relates to a kind of composite core cableway steel wire rope and its manufacture method, belong to metal product processing technique field.
Background technology
At present, its wire rope core generally use PPC core of the manufacture of cableway steel wire rope, the cableway steel wire rope of PPC cores production, steel wire rope
Diameter is bigger by 2%~4% than under working status in a relaxed state, and structural instability, structural stretch is big, to rope strand support effect not
Good, after using pre- tensioning to steel wire rope, steel cord structure stability is also undesirable, and rope strand breakoff phenomenon still occurs in use,
Reduce service life of steel wire rope.
The content of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of composite core cableway steel wire rope and its manufacture
Method, solves cableway steel wire rope structural instability, the technical problems such as service life is low.
Technical scheme：
（1）Metal stock core is added among sticking plaster；
（2）Sensing heating is carried out to metal stock core using intermediate frequency furnace, then transfers heat to plastics, so as to reach soft plastics
Purpose；
（3）Using Forming die and sizing roller, between the plastics after softening are expressed to outer strands gap, and to the diameter of steel wire rope
Shape with out-of-roundness.
The composite core cableway steel wire rope of the present invention is twisted with the fingers multiply outer strands by a sticking plaster core and outsourcing and is formed, sticking plaster
Core center is a metal stock core.
The number of share of stock of the outer strands of the present invention is no less than 4 strands, is preferably 6 strands and 8 strands, outer strands steel wire number many 7
Root, structure is 1 × 7,1 × 19,1 × 19W, 1 × 19S, 1 × 26WS, 1 × 31WS, 1 × 36WS, 1 × 41WS, 1 × 55SWS etc..
The metal stock cored structure of the present invention is 1 × 3,1 × 7,1 × 19,1 × 19W, 1 × 19S etc.
The plastic layer one-sided thickness of the sticking plaster core of the present invention is 1-12mm, is preferably 2.5-6mm.
The manufacture method of the composite core cableway steel wire rope of the present invention, is provided with intermediate frequency furnace between actinobacillus device and crank closer
Heating unit, during torsade, sticking plaster core is heated after actinobacillus device releasing by intermediate frequency furnace induction heating apparatus, soft plastics rod
Core outer layer plastic, the sticking plaster core softened at Forming die close up with outer strands, are twisted into rope, then are molded through sizing roller, outside
Layer stock is tightly combined with sticking plaster core, and steel cord structure is stablized.
Beneficial effects of the present invention：
1st, support effect is more preferable
Support effect is more much better than domestic usually used PPC core cableway steel wire ropes, according to the cableway produced using experience PPC cores
Rope, its wirerope diameter are bigger by 2%~4% than under working status in a relaxed state.Composite core in a relaxed state with work shape
Diameter has almost no change under state.
2nd, steel wire stable mechanical performance
Open firing soft plastics are used during production before Forming die, in the heating process carried out to plastics while also to steel
Cord stock is heated, and strand wire causes the decline of steel wire mechanical performance in strand wire after being heated tempering.Composite core
It is to have added a metal stock core among sticking plaster, intermediate frequency furnace can be used to carry out sensing heating to stock core, then by stock core to modeling
Material is heated.Avoid damage of the open firing to steel wire.
3rd, the stabilization of steel cord structure
Sticking plaster surface each point temperature is inconsistent during open firing, and plastics softening is just inconsistent, can cause the modeling between each stock gap
Expect that loading is inconsistent, it is inconsistent also to have resulted in support of the plastics to each stock, and support is inconsistent to have resulted in steel cord structure
It is unstable.Composite core can accomplish that 360 degrees omnidirection heats, ensure that the one of plastics softening using intermediate frequency heating
Cause property, the filling plastic amount between each stock gap is consistent, can effectively ensure that the stabilization of steel cord structure.
4th, structural stretch is small, life cycle management nipple number is few
Domestic common PPC cores cableway steel wire rope structural stretch is 0.3% or so generally after 0.8% or so, pre- tensioning, passes through examination
Verification, composite core can reach less than 0.1% without pre- tensioning.
5th, reduce pre- tensioning link, save production and application cost
Composite core cableway steel wire rope can reach less than 0.1% without the elongation of pre- tension structure, so in week life-cycle of cableway rope
The connector number during user's use can be reduced in phase.Without pre- tensioning, production cost has been saved.Connector number is few, saves
The use cost of user.
6th, using intermediate frequency furnace sensing heating more safety and environmental protection
Compared with foreign countries using open firing soft plastics, use smoke dust, the flames of anger, environment temperature during intermediate frequency furnace sensing heating
It is low, so using intermediate frequency furnace sensing heating more safety and environmental protection.
In general its support effect of cableway steel wire rope and steel cord structure stability for being produced with composite core are more preferable, diameter
With steel wire mechanical performance is more stable, structural stretch is small, few without pre- tensioning, life cycle management nipple number, saved production
Cost and customer using cost, and more safety and environmental protection.
