(57) Abstract:

The invention relates to the field of hardware industry and can be used in the production of steel cords and multi-layer ropes, and cables. The essence of the invention is to improve the quality of twisted metal fabrication products. A method of manufacturing twisted metal products, wherein forming the channel threads perform the translational motion in one plane, which in turn rotates around the axis of the curl, while maintaining a fixed orientation in space, while the threads do longitudinal movement in this plane in the direction parallel to the axis of curl and with a constant eccentricity of the Central threads about the axis of the curl, then doing the first area of the curve coinciding with the plane perpendicular to the axis of twisting threads acquire the direction of longitudinal movement at an angle to the axis of the curl being formed on this axis in a convergent beam, simultaneously with the formation of a beam is loaded on this axis one revolution along a helical line coincident with the direction of rotation around the axis of the twisting of the first areas of inflection, resulting in about the individual threads, which diverge in the radial direction at an angle to the axis of the curl, and all the divergent threads lie in the same plane, receiving the rotation around the axis of the curl, then diverging threads by longitudinal movement serves the second zone of inflection, located in the plane perpendicular to the plane in which are divergent threads, and change in this zone, the direction of the longitudinal movement of divergent threads, re-directing them to the axis of the curl until the entrance of the threads in the third zone of inflection corresponding to the plane perpendicular to the axis of twisting, passing through the point of intersection of the Central thread with the specified axis, and rotating around this axis, at the same time turning the plane into the side strands around a Central filament, and in the third zone of inflection is formed beam, converging then at one point on the main thread, coinciding with the axis of the curl, which produces torsion beam filaments around a Central thread, and move it further along the centerline with the subsequent winding of the twisted product on the drum. 3 Il.

The invention relates to hardware industry and can be used in the production of steel cords and mneak crossing threads, their exit from the inner layers, the outer, insufficient tension wires, the inability to receive all made of the length of the rope (strands) on the drum, the obligatory presence of the filament winding machines for winding wire on the sets of coils. All this leads to a reduction in the quality of the product and its performance and durability, as well as the cost of production.

A known method of manufacturing wire ropes of double strand (ed. St. N 622905 class. D 7 B 3/00), including the lay of the strands of the wires and the subsequent strand of rope strands to twist them one turn on the step-strand rope, while strand strands of wire strands additionally reported residual torsional strain. The strand strands is due to the rotation of the rotor pradeshiya machine and rotation of the strands with the help of endless rolling clip. In the winding rotating strands on the stationary drum she reported the initial residual torsional strain.

The disadvantage of this method is that it does not exclude the possibility of a crossing of the threads, their exit from the inner layers to the exterior due to the fact that the distribution of threads layers produced in the initial stage of the process of twisting.

It is also possible n the known methods of obtaining the ropes closest to the technical essence is a method of making twisted metal products (patent Germany N 3802631, CL D 7 B 3/10).

A method of manufacturing twisted metal products consists of winder plane-parallel threads (swebok) with sets of coils in the area of education twisted products; forced by the helical movement of the beam twisted yarn, supply products on a winding drum on the bend of the trajectory, the beginning and end of which are located on the same axis, so that the movement of the twisted product was opposite to its movement in the beginning of the trajectory, the force of rotation located on a curved path segment twisted products around connecting the beginning and end of the trajectory axis with a speed component of half the rotation speed of twisted products in the area of education, the coiling of the product on the drum under tension force.

The disadvantage of the method of manufacturing twisted metal products lies in the fact that this method does not exclude the possibility of occurrence of negative phenomena as explained, the output of the filaments of the inner layers, the outer, the uneven tension of the individual strands, the strand of complex products with raznomastnye the original thread, because the distribution of filaments twisted product is made at the beginning of the durability.

The aim of the present invention is to improve the quality of twisted metal fabrication products.

This objective is achieved in that in the method of manufacturing twisted metal products, including the winding plane-parallel threads (swebok) with the supply coils, double torsion beam filaments and winding the resulting product was placed on the drum, according to the invention, when the winding with the setting coils of yarn make a movement in one plane, which in turn rotates around the axis of the curl, while maintaining a fixed orientation in space, while the threads do longitudinal movement in this plane in the direction parallel to the axis of curl and with a constant eccentricity of the Central threads about the axis of the curl, then entering the first area of the curve coinciding with the plane perpendicular to the axis of twisting threads acquire the direction of longitudinal movement at an angle to the axis of the curl being formed on this axis in a convergent beam, and simultaneously with the formation of a beam is loaded on this axis one revolution along a helical line coincident with the direction of rotation around the axis of the twisting of the first areas of inflection, in restiana beam into separate threads, which diverge in the radial direction at an angle to the axis of the curl, and all the divergent threads lie in the same plane, receiving the rotation around the axis of the curl, then diverging threads by longitudinal movement serves the second zone of inflection, located in the plane perpendicular to the plane in which are divergent threads, and change in this zone, the direction of the longitudinal movement of divergent threads, re-directing them to the axis of the curl until the entrance of the threads in the third zone of inflection corresponding to the plane perpendicular to the axis of twisting, passing through the point of intersection of the Central thread with the specified axis, and rotating around this axis, at the same time turning the plane into the side strands around a Central filament, and in the third zone of the bend formed in the beam converging then at one point on the main thread, coinciding with the axis of the curl, which produces torsion beam filaments around a Central thread, and move it further along the centerline with the subsequent winding of the twisted product on the drum.

As a result of these operations increases the density of the twisted product, excludes such phenomena as the crossing and the Fig. 1 shows a diagram of twisted metal fabrication products; Fig. 2 is a side view from the entrance of the threads of Fig. 3 is a view from the outlet side of the filaments of the second zone.

A method of manufacturing twisted metal products as follows: sativas with sets of coils 1 thread 2 make longitudinal movement in the plane 3, which in turn rotates around the axis of the twisting 4, while maintaining a fixed orientation in space, while thread 2 make longitudinal movement in the plane 3 in the direction parallel to the axis of the twisting 4 and with a constant eccentricity of the Central filament 5-axis twisting 4 then doing in the first zone of the curve, coinciding with the plane perpendicular to the axis of curl 4, filaments 2.5 to acquire the direction of longitudinal movement at an angle to the axis of the twisting 4, being formed on this axis in a convergent beam, and simultaneously with the formation of the beam 6 is wound on the axis one revolution of the beam 6 along a helical line coincident with the direction of rotation around this axis twisting 4 in the first zone of the curve, resulting in the twisting threads of 2.5 between them, then after one turn, produce the opposite RAS, all of the divergent strands of 2.5 are located in one plane 7, the receiving rotation around the axis of the twisting 4, then the divergent strands of 2.5 by longitudinal movement serves the second zone of inflection placed in the plane perpendicular to the plane in which are located the divergent strands of 2.5 and change in this zone, the direction of the longitudinal movement of the divergent threads of 2.5, re-directing them to the axis of the twisting 4 up to the entrance of the threads in the third zone of inflection corresponding to the plane 8 perpendicular to the axis of curl 4, passing through the point of intersection of the Central line 5 with the specified axis, and rotating around this axis, simultaneously rotating the plane of 3.7 with a thread 2,5 around the Central filament 5, and in the third zone of inflection threads are formed in the beam 9, convergent, then at one point and passing through the matrix 10 to the Central filament 5, which coincides with the axis of curl 4, which produces torsion beam 9 thread 2 around the Central filament 5, and move further with the subsequent winding of the twisted product 11 to the receiving drum 12.

The proposed method of producing twisted metal products in comparison with the known allows to increase the density of the woven product, to avoid their every thread in the woven product.
