Abstract
The invention discloses a shaped steel cord thread and a shaped steel twisted wire. The cross section of the shaped steel cord thread is shaped like a circular ring section or an approximate circular ring sector, and the central angle of the circular ring section or the approximate circular ring section is 360 DEG/n, wherein n is a natural number more than or equal to 3. The invention aims to provide a shaped steel cord thread which is more widely applied in manufacturing of steel twisted wires of different identifications and different layers. The shaped steel twisted wire comprises a central core wire with a round cross section and a steel cord thread winded outside the core wire, wherein more than one layer of the steel cord thread is winded outside the core wire, and any cross section of the winded steel cord thread is shaped like the circular ring sector or the approximate circular ring sector, and the identifications of the steel cord threads on the same layer are the same, and the shapes and areas of the shaped cross sections are the same. The invention aims to provide the shaped steel twisted wire. The friction force among the steel cord threads in the shaped steel twisted wire is large and therefore prevents slipping between layers and makes the force pressed on the steel twisted wire relatively uniform, so that the service life of the shaped steel twisted wire is prolonged.
Description
Technical field
The present invention relates to a kind of steel cord and steel strand wires, particularly a kind of deformed steel cord and a kind of deformed steel twisted wire.
Background technology
Now, it is circular mostly steel cord shape of cross section is, the steel cord contact-making surface each other of circular cross section is too little, is generally the line contact, less contact-making surface must make frictional force each other reduce, make the steel strand wires layer that is processed into by circular cross section with layer between slip phenomenon appears easily.
At present, normally used 1*7 steel strand wires are to be that a circular cross section steel cord turns to circular steel cord round the center by six cross sections of one deck.Because steel strand wires are widely used in every field such as highway, railway, bridge, building, along with the needs of large-engineering more, also increasing to the load bearing requirements of steel strand wires, present normally used 1*7 steel strand wires can not satisfy the demand that further develops.Usually, the diameter of forming the single steel cord of steel strand wires all is directly proportional with the carrying and the hardness of steel strand wires, and single steel cord diameter can not unrestrictedly increase in the 1*7 steel strand wires, and large diameter 1*7 steel strand wires are because of the excessive very difficult input practical application of hardness.The increase of the steel strand wires number of plies has become development trend, yet, the structure of composite steel twisted wire makes it be difficult for adopting the steel cord coiling of traditional circular cross-section again, reason is that the steel cord contact-making surface each other of circular cross section is too little, be generally the line contact, less contact-making surface must make frictional force each other reduce, slip phenomenon appears easily between layer and the layer, in case slippage just causes the discontinuity between the ectonexine, extra-heavy one deck can be damaged prematurely, influences the service life of whole steel strand wires.
Summary of the invention
The objective of the invention is customer service deficiency of the prior art, a kind of deformed steel cord and a kind of deformed steel twisted wire are provided.
In order to address the above problem, the invention provides a kind of special-shaped cross-section steel cord, this profiled cross-section steel cord shape of cross section is circle ring sector or approximate circle ring sector, wherein the central angle of circle ring sector or approximate circle ring sector is 360 °/n, wherein n is the natural number more than or equal to 3, and approximate circle ring sector is meant that the interior circular arc of circle ring sector is the straight line that two-end-point connects.
The technical scheme of the deformed steel twisted wire among the present invention is: the deformed steel twisted wire comprises that one at center is as the circular cross section steel cord 1 of heart yearn be wrapped in this heart yearn outside steel cord 2, the heart yearn outer felt around the number of plies of steel cord be more than one deck, the cross section of the steel cord of arbitrary winding is circle ring sector or approximate circle ring sector, and identical with the model of one deck steel cord, the special-shaped cross-section shape is identical with area.
In this deformed steel twisted wire the heart yearn outer felt around the number of plies of deformed steel cord represent that with C C is optional in 1,2,3,4 layer, the heart yearn outer felt around the number of plies of deformed steel cord be one deck or two-layer more suitable.
In this deformed steel twisted wire the heart yearn outer felt around the deformed steel cord in the number of ground floor deformed steel cord represent that with n n is the natural number more than or equal to 4, be preferably 5-7.
In this deformed steel twisted wire the sum (representing) of steel cord and heart yearn outer felt with N around the number of plies (C) of deformed steel cord and the number (representing) of ground floor deformed steel cord with n closely related, promptly N=1+ (2
0+ 2
1+ 2
2+ ... + 2
(C-1)) n, the steel cord adds up to 19 (they being C=2, n=6), 7 (being C=1, n=6), 8 (they being C=1, n=7) are more suitable.The model of steel strand wires represents with 1*N that generally 1*19,1*7, the above deformed steel twisted wire ratio of 1*8 one deck are easier to coiling so, are the preferable models that more often has.
Approximate circle ring sector is meant that the interior circular arc of circle ring sector is the straight line that two-end-point connects in this deformed steel twisted wire.
The invention has the beneficial effects as follows:
1, the beneficial effect of deformed steel cord of the present invention:
Deformed steel cord of the present invention can be widely used in making the steel strand wires of different model, the different numbers of plies, deformed steel cord of the present invention is being used to make steel strand wires especially during the more steel strand wires of the number of plies, because the contact-making surface between the deformed steel cord increases, frictional force increases, make and be not easy to occur slippage between prepared steel strand wires layer and the layer, prolong the service life of steel strand wires, thereby made deformed steel cord of the present invention more be widely used in the steel strand wires of making various models, the different numbers of plies than circular cross section steel cord.
2, the beneficial effect of deformed steel twisted wire of the present invention:
(1) be not easy to occur slip phenomenon between deformed steel twisted wire middle level of the present invention and the layer, this is because cross section is bigger for the mutual contact-making surface of special-shaped steel cord, the cause that frictional force increases.
(2) deformed steel twisted wire of the present invention is whole stressed even, prolonged service life, because frictional force increase between the steel cord in the deformed steel twisted wire of the present invention, be not easy to occur part steel strand wires slip phenomenon in the use, thereby make deformed steel twisted wire of the present invention whole stressed even, prolonged the service life of deformed steel twisted wire of the present invention.
