Description

DEVICE FOR MANUFACTURING TWO-LAYER TWISTED WIRE WIRE PRODUCTS

The utility model relates to metallurgical production, in particular to devices for the production of double-layer twisted wire products for reinforcing tires, conveyor belts, high-pressure hoses and other rubber products, as well as ropes and cables.

A device 1 for the manufacture of twisted wire products containing the supply coils, the primary lay zone, “balloon, secondary lay zone, torsion block, receiving coil, distribution template, dies is known.

The disadvantage of this device is that for the manufacture of two-layer twisted wire products with the same or different directions of layering layers and different steps of layering in layers, you need a second device 2, Fig. 3 for the preliminary manufacture of the core in a separate technological operation.

As a prototype, a Barmag 2 RIR machine was adopted, Fig. 5, containing a dual-core unwinding device, spinning devices (rotational unwindings) for 15 unwinding units for the outer layer wires similar in design to the core unwinding unit, distribution template, dies, rotating loop , paddle wheels, exhaust mechanism, leveling device, stacker and winder.

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

The problem solved by the utility model is to create a device that provides the ability to manufacture two-layer twisted wire products in one technological operation with different lay steps.

The technical result obtained using the utility model is to exclude a separate core manufacturing operation in the production of two-layer twisted wire products.

The solution to this problem is provided by the fact that the device for the manufacture of two-layer twisted wire products includes a static unwinding module or a module for rotational unwinding of wires of the outer layer of a twisted wire product, a double twist module of a twisted wire product, an additional module of double pre-lay of the core.

An additional module of double - preliminary lay of the core, contains from 2 to 7 feed coils of core wires.

The rotary unwinding module includes 18 feed coils with knots for twisting the wires of the outer layer of the twisted wire product.

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

The difference between the claimed solution and the prototype is that the device includes an additional module of double preliminary lay of the core with 2 ... 7 supply coils. The module of double twisting of a twisted wire product includes a torsion device, and the module of rotational unwinding includes 18 supply coils with nodes for twisting-twisting the wires of the outer layer of the twisted wire product.

The utility model is illustrated by the drawing, in which Fig. 1 shows the design of a device for manufacturing two-layer wire products in one technological operation with different steps of twisting of the core wires and the outer layer.

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

IPC B 21 F 7/00 D 07 V 3/00

The additional module of double preliminary lay (3) includes from 2 to 7 feed coils of core wires (4), rotors (6) and flywheels (7).

The double twist module of a twisted wire product (2) includes an exhaust device (8), a distribution template (10), a forming sleeve (11), crimp dies (12), drive rollers (13), flywheels (14), a reversing roller (15), a torsion device (16), a correct device (17), and a receiving coil (18).

The device operates as follows: unwinding the first group of wires that form the core from the supply coils (4) and their slipping into the core (5) in the double lay module (3) with a preliminary lay to.

The wires are twisted into the core due to the rotational movement of the rotors (6) and flywheels (7) of the double preliminary twist core module (3) and the translational movement of the core with a linear drawing speed YC, which is set by the exhaust device (8) of the double twist module of a two-layer twisted wire product (2) and, accordingly, is equal to the linear drawing speed of the steel cord Ym.

The next stage is the passage of the core, formed with a preliminary step to and the second group of wires of the outer layer from the feeding coils (9) of the module for static or rotational unwinding of wires (1), through the distribution template (10), the forming sleeve (11) and crimping dies (12 ) to form an outer layer around the core.

The next stage involves feeding the preformed twisted wire product to the drive rollers (13), the flywheels (14), the reversing roller (15), the exhaust device (8), the torsion device (16), the correct device (17) and to the receiving coil (18) of the module double twist of a twisted wire product (2) in which the twisted wire product is twisted with the set spacing tm. Simultaneously with the process of twisting the twisted wire product, the preliminary twisting step of the core twisting to is twisted to the final step tk, if the core and the outer layer of the twisted wire product have the same direction of twisting (SS or ZZ). In this case, the direction of rotation of the rotors and flywheels of the double core pre-lay module (3) and the double twist module of twisted wire products (2) is opposite (SZ or ZS).

If the twisted wire product has the opposite direction of the core and outer layer stranding, in this case, during the twisting of the twisted wire product with the stitching step tm, in the double stitching module of the twisted wire product (2), the preliminary core stitching step untwists to the final stitching step tk. In this case, the direction of rotation of the rotors and flywheels of the double core pre-lay module (3) and the double twist module of twisted wire products (2) is the same (SS or ZZ)

The use of this device allows the manufacture of double-layer twisted wire products by the method of double lay with different steps of lay of the core wire and the outer layer in one technological operation. In this case, the core can be twisted from 2 ... 7 wires, and the outer layer from 4 ... 18 wires of the same or different diameters, preferably from coated or uncoated wires, made of stainless steel with a carbon content of 0.65 ... 1.0%
