Description

(54) DEVICE FOR MANUFACTURING WIRED PRODUCTS WITH A VARIABLE DIRECTION OF SWIRL

one

The invention relates to cable and cable production, namely to devices for making twisted wire products with a variable stranding direction.

A device for manufacturing twisted products with a variable direction of winding is known, comprising a mechanism for feeding the swiveling elements mounted on the base along the technological process, a twisting mechanism with a reversible rotational drive and a receiving mechanism 1.

A disadvantage of this device is that it does not unscrew the twisted elements, and as a result of friction in the channels of the twisting mechanism, a moment occurs preventing the passage of twisting from elements with the opposite direction of the twist to the right and left of the mechanism. As a result, a significant technological torque arises in the product, which reduces the strength and durability of the product.

The aim of the invention is to eliminate this disadvantage and increase the quality of the product.

The goal is achieved by the fact that in a device comprising a feed mechanism for the elements to be twisted, a stitching mechanism with a reversible rotation drive and a receiving mechanism, the stitching mechanism is provided with an unscrewing knot at the same distance from its axis of rotation with the possibility of rotation relative to its axes, kinematically associated with the drive of the rotation of the slewing mechanism and made each in the form of dies or in

To the form of a few rounding swivel element rollers.

FIG. 1 shows the device, general view, section; in fig. .2 - unscrewing knot with dies; in fig. 3 - the same, 5 with rollers.

Claims (3)

The device for twisting the articles includes a mechanism 1, a feed element 2 of the rope, a receiving mechanism 3, as well as a folding mechanism 4 mounted on a bearing 5. On the mechanism 4 rotatably unscrew assemblies 6, each of which is rigidly connected to the driven brush 7. The latter are in engagement with the end 8, which is driven in rotation by the gear 9. The curling mechanism 4 and the gear 7 and the end 8 are interconnected by means of gear 10 and 9, which are rigidly fixed to the drive shaft I. The twisting nodes 6 can be in They are made in the form of either dies 12 and 13 that cover the swiveling element 2, compressing it with some force, or one or more rollers 14 that are rotatably mounted on the bracket 15 and are covered by the swiveling element 2. At the same time, the diameter and deflection of the elements on the rollers choose from the conditions of the perforation of elements. The device works as follows. The mechanism 1 feeds the elements 2 of the rope to the twisting mechanism 4. The drive shaft 11 rotates the mechanism 4 in variable directions, which allows the finished rope to be twisted. At the same time, gear 9 rotates gears 7 with gears 6 fixed to them by means of unscrewing units 6 in the direction opposite to the rotation of the twisting mechanism 4. This eliminates the torsion of elements 2 caused by twisting them into the rope. The finished rope is wound up by the receiving mechanism 3. The adjustment of the unscrewing is carried out by selecting the gears 9 and 10 so that the total gear ratio from the mechanism 4 to the nodes is:. COS ot, where d is the angle of twisting of the elements in the rope. The application of the invention allows to eliminate the adverse effect of the technological twisting of the elements, which increases the strength and operability of products with a variable twist direction by 15-20%. Claim 1. A device for the manufacture of twisted products with a variable direction of lay, containing installed on the basis of the process, the process of feeding the swivel elements, twisting mechanism with a drive reverse rotation and receiving mechanism, in order to improve the quality of products the folding mechanism is equipped with equal distances from its axis of rotation mounted for rotation with respect to its axes by unscrewing knots according to the number of elements to be twisted, kinematic connected with the rotation drive of the folding mechanism. 2. A device according to claim 1, characterized in that each twist-off assembly is made in the form of dies. 3. The device according to claim 1, characterized in that each twist-knot assembly is made in the form of several rollers which are twisted around by a swiveling element.
