External winding wire pre-deformation and tension control device for steel cord

Abstract

The invention relates to an external winding wire pre-deformation and tension control device for a steel cord. The device comprises a motor main shaft, a spool, a pre-deformation assembly, a flying wing assembly, a magnetic assembly and an aluminum alloy jacket are sequentially arranged on the motor main shaft, a main shaft rope outlet alloy nozzle is arranged at the side end of the motor main shaft, a steel cord main body horizontally penetrating through the motor main shaft is arranged in the motor main shaft; the pre-deformation assembly comprises a pre-deformation disc arranged on the circumferential outer wall of the motor main shaft in a sleeving mode; the flying wing assembly comprises a flywheel and a wear-resistant ring which are sequentially connected in parallel; and the magnetic assembly comprises a magnetic disc and a magnetic column, a gap is reserved between the magnetic disc and the magnetic column, and the magnetism of the side, adjacent to the magnetic column, of the magnetic disc is opposite. The device has the advantages that the pre-deformation amount of the steel wire and the tension of the external winding wire can be effectively controlled, the steel wire is more tightly attached to the steel cord main body, and the product quality of the OTR steel cord of the external winding wire structure can be remarkably improved.

Description

technical field [0001] The invention relates to the field of steel cord processing, in particular to an outer winding wire pre-deformation and tension control device for steel cords. Background technique [0002] At present, the steel cords used in OTR tires for mines are mainly outer-wound wire structures. The production of tire cord fabrics is mainly an extrusion process. Broken wires will cause quality risks and a large number of waste products; in the production process of steel cords, the outer winding wires need to be close to the main body of the steel cord, which requires that the outer winding wires have a certain amount of deformation and post-drawing tension. The existing technology The pay-off tension is controlled by a pair of friction pairs. After a period of use, with the wear of the friction pairs and the small particles formed, the tension will fail, and the tightness of the outer winding wire will be inconsistent, which will affect the product quality; at t...

[0002] At present, the steel cords used in OTR tires for mines are mainly outer-wound wire structures. The production of tire cord fabrics is mainly an extrusion process. Broken wires will cause quality risks and a large number of waste products; in the production process of steel cords, the outer winding wires need to be close to the main body of the steel cord, which requires that the outer winding wires have a certain amount of deformation and post-drawing tension. The existing technology The pay-off tension is controlled by a pair of friction pairs. After a period of use, with the wear of the friction pairs and the small particles formed, the tension will fail, and the tightness of the outer winding wire will be inconsistent, which will affect the product quality; at the same time, because the existing technology does not A control method for the pre-deformation of the outer winding wire is proposed. The amount of pre-deformation fluctuates with different positions of the I-shaped wheel, which also leads to inconsistent tightness of the outer winding wire when forming on the steel cord, which leads to the risk of wire breakage in customer applications.
