Abstract
A kind of face contact multiply cable core that the utility model is related to, it is characterized in that it includes internal central hair and exterior six roots of sensation outer layer strand, the surface of outer layer strand is provided with zinc coat, a diameter of 1.6mm of the central hair, a diameter of 0.86mm of the outer layer strand, face contact multiply cable core surface is by forging to form circular cross-section, fitted closely between face contact multiply cable core central hair and outer layer strand after forging, fitted closely between adjacent outward layer stock, a diameter of 3.2 ± 0.03mm of the entire surface contact multiply cable core after forging.The advantages of the utility model face contact multiply cable core has that cost is relatively low, and the contact stress of steel wire is low, surface is smooth and dimensional accuracy is high.
Description
Technical field
It the utility model is related to a kind of face contact multiply cable core.
Background technology
At this stage, most domestic push-and-pull cable core is ordinary lines point contact, line contact cable core, and such cable core is protected with outer layer
The contact of pipe is point contact, line contacts, and contact surface is small, and contact stress is big, be easy to cause pillar inner wall abrasion.And such cable core
Surface irregularity, planarization is poor, and in bending, torsion, cable core and the contact that pillar inner wall is each put are different, this just leads
Cause the power that every section of pillar is born also inconsistent, assembly can cause every section of unbalance stress when in use, be easy to cause assembly and locally become
Shape.In addition, the density metal coefficient of point contact, line contact cable core is smaller, wear-resisting property is poor, bearing capacity is small, anti-fatigue performance
It is bad, service life is short.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of cost is relatively low, and the contact stress of steel wire is low, table
The face contact multiply cable core that face is smooth and dimensional accuracy is high.
What the purpose of this utility model was realized in：
A kind of face contacts multiply cable core, it is characterised in that it includes internal central hair and exterior six roots of sensation outer layer strand, outside
The surface of layer stock is provided with zinc coat, and a diameter of 1.6mm of the central hair, a diameter of 0.86mm of the outer layer strand, face connects
Multiply cable core surface is touched by forging to form circular cross-section, it is tight between the face contact multiply cable core central hair and outer layer strand after forging
Closely connected conjunction, fits closely between adjacent outward layer stock, a diameter of 3.2 ± 0.03mm of the entire surface contact multiply cable core after forging.
Compared with prior art, the beneficial effects of the utility model are：
The utility model face contact multiply cable core is carried out after forging compacting, and outer layer strand flattens, and intermediate gap reduces, outer layer strand
The face that contact between outer layer strand is become compaction state by point contact contacts, and contact surface is big, the point with same specification with intensity
Contact, line contact cable core compare, the contact stress of steel wire is relatively low in cable core, and the density metal coefficient of cable core is larger, have it is wear-resisting,
The advantages that large carrying capacity, anti-fatigue performance are good, service life is long, in addition also has that cost is relatively low, the contact stress of steel wire is low,
Surface is smooth and the advantages of dimensional accuracy is high.
Brief description of the drawings
Fig. 1 contacts multiply cable core structure diagram for the utility model face.
Fig. 2 is the structure diagram of stamping machine.
Wherein：
Outer layer strand 1, central hair 2.
Embodiment
Referring to Fig. 1, a kind of face contact multiply cable core that the utility model is related to, it is including internal central hair 2 and outside
Portion's six roots of sensation outer layer strand 1, the surface of outer layer strand 1 are provided with zinc coat, a diameter of 1.6mm of the central hair 2, the outer layer strand 1
A diameter of 0.86mm, the outer layer strand 1 is 1*7 models, face contact multiply cable core surface by forging to form circular cross-section,
Fitted closely between face contact multiply cable core central hair 2 and outer layer strand 1 after forging, fit closely, forge between adjacent outward layer stock 1
A diameter of 3.2 ± 0.03mm of entire surface contact multiply cable core after beating.
Principle：
Outer layer strand 1 is wound on the outside of central hair 2, the method forged by stamping machine, by between the central hair of outer layer strand,
Compaction state is showed between outer layer strand and outer layer strand.
Referring to Fig. 2, the mode of production for forging face contact cable core is rotated by the high speed of ball, and pintongs group is promoted by forging hammer
Into circular die impact among cable core promote its deformation.In deformation process, outer layer strand flattens cable core, and intermediate gap subtracts
Small, the face that the contact between outer layer strand and outer layer strand is become compaction state by point contact contacts.
It is a set of independent production equipment in itself to forge equipment, for the product shaped, if by cable core
Twisting can be achieved to forge online with forging to combine, so as to significantly improve production efficiency.
