Description

The utility model relates to the metallurgical industry, and more specifically to devices for the production of double-layer wire products for reinforcing tires, conveyor lines and other rubber products, as well as ropes and cables.

A device |(1| for the production of twisted wire products is known, which contains a request coil, a primary winding zone, a "balloon", a repeated winding zone, a torsion assembly, a receiving coil, a distribution template, dies.

The disadvantage of this device is that for the production of two-layer twisted wire products with the same or different winding directions in the layers, a second device (2, Fig. 3) is needed for the preliminary production of the core in a separate technological operation.

As a prototype, we adopted the BOJ machine of the "Barmag" company (2, fig. 5 |), which contains a unwinding device for double twisting of the core, unwinding devices (rotational unwinding) for 15 unwinding nodes for the wires of the outer layer, similar in design to the core unwinding node, a distribution template, dies, a rotary loop, blade wheels, an extraction mechanism, a straightening device, a stacker, and a winding device.

The disadvantage of the prototype is that the machine does not provide winding of two-layer wire products in one technological operation with different steps of twisting the core and the outer layer.

The problem solved by the useful model consists in the creation of a device that provides the possibility of manufacturing two-layer twisted wire products in one technological operation with different steps of twisting.

The technical result obtained when using a useful model consists in the exclusion of a separate core manufacturing operation in the production of two-layer twisted wire products.

The solution to the problem is provided by the fact that the device for the production of two-layer twisted wire products contains a module of static unwinding or a module of rotary unwinding of wires of the outer layer of a twisted wire product, a module of double twisting of a twisted wire product, an additional module of double - preliminary twisting of the core.

The optional double-pre-twist core module contains from 2 to 7 request coils of core wires.

The rotary unwinding module contains 138 inquiry coils with nodes for unwinding and twisting the wires of the outer layer of the wire product.

The double-twist module of the twisted wire product contains a torsion device.

The difference between the proposed solution and the prototype is that the device contains an additional module of double-pre-twisting of the core with 2...7 request coils. The double-twisting module of the twisted wire product contains a torsion device, and the rotary unwinding module contains 18 request coils with nodes for unwinding - twisting the wires of the outer layer of the wire product.

A useful model is explained by the drawing, where in fig. shows the design of the device for the production of two-layer twisted wire products in one technological operation with different steps of twisting the wires of the core and the outer layer.

The design includes a module for static or rotary unwinding of wires of the outer layer (1), a module for double twisting of a two-layer twisted wire product (2) and an additional module for double pre-twisting of the core (3).

The static unwinding module contains 18 request coils (9) for the wires of the outer layer of the twisted wire product.

The rotary unwinding module contains 18 request coils (9), with unwinding-winding units for the wires of the outer layer of the wire product.

The additional double core pretwist module (3) contains 2 to 7 core wire request coils (4), rotors (6) and flywheels (7).

The double-twisting module of the twisted wire product (2) contains the drawing device (8), the distribution template (10), the forming sleeve (11), the crimping dies (12), the guide rollers (13), the flywheels (14), the reversing roller (15). , torsion device (16), correct device (17), and receiving coil (18).

The device works in the following way: unwinding the first group of wires forming the core from the request coils (4) and twisting them into the core (5) in the double-twist module (3) with a previous twisting step o.

The twisting of the core wires is carried out due to the rotational movement of the rotors (6) and flywheels (7) of the double pre-twisting module (3) and the translational movement of the core with the linear speed of the drawing Us, which is set by the drawing device (8) of the double-twisting module of the two-layer twisted wire product (2 ) and, accordingly, is equated to the linear speed of metal cord extraction ХУ t.

The next stage is the passage of the core, formed with the previous step of twisting it and the second group of wires of the outer layer from the request coils of the second group of wires of the outer layer from the request coils (9) of the static or rotary wire unwinding module (1), through the distribution template (10), forming sleeve (11) and crimping dies (12) to form the outer layer around the core.

A further stage involves feeding the preformed twisted wire product to the drive rollers (13), flywheels (14) reversing roller (15) draw device (8), torsion device (16), correct device (17) and to the receiving coil (18) of the module double twisting of the twisted wire product (2) in which the twisted wire product is wound with a set twist step (i.e. Simultaneously with the process of twisting the twisted wire product, the twisting of the previous step of twisting of the core io to the final step ik is carried out in the case that the core and the outer layer of the twisted wire product have the same twist direction (55 or 72), while the direction of rotation of the rotors and flywheels of the core double pretwist module (3) and the twisted wire product double twist module (2) is opposite (52 or 25).

If the twisted wire product has the opposite direction of twisting of the core and the outer layer, in this case, in the process of twisting the twisted wire product with the twisting step yt, in the module of the double twisting of the twisted wire product (2), the previous twisting step of the core is untwisted until the final twisting step yk. At the same time, the direction of rotation of the rotors and flywheels of the module of the double pretwisting of the core (3) and the module of the double twisting of the twisted wire product (2) is the same (55 or 272)

The use of this device allows the production of two-layer twisted wire products by the method of double twisting with different steps of twisting the wires of the core and the outer layer in one technological operation. At the same time, the core can be wound from 2...7 wires, and the outer layer from 4...18 wires of the same or different diameters, preferably coated or uncoated wires made of high-quality steel with a carbon content of 0.65... ..1.0905.
