Rewinding straightening device for tire bead steel wires

Abstract

The invention relates to a rewinding straightening device for tire bead steel wires, which comprises an unwinding shaft, a winding shaft and a rewinding straightening mechanism. The rewinding straightening mechanism comprises a tension sensing wheel rotatablly arranged, a first ceramic wheel rotatablly arranged, a second ceramic wheel rotatablly arranged, a traction wheel rotatablly arranged and a straightener. Steel wires unwound from the unwinding shaft are wound on the tension sensing wheel and the first ceramic wheel, the steel wires wound out from the first ceramic wheel pass through the second ceramic wheel and then are wound on the traction wheel, the steel wires wound out from the traction wheel pass through the straightener and then are wound on the winding shaft driven by a motor, a sensing device is installed on the tension sensing wheel, the output end of the sensing device is in signal connection with a programmable logic controller (PLC), and the PLC is in signal connection with the motor through a frequency converter to control rotation speed of the motor. The rewinding straightening device for the tire bead steel wires has the advantages of reducing scrapping caused by poor winding displacement; and removing residual stress inside the steel wires through re-straightening and accordingly not reducing mechanical property of the steel wires caused by overlarge residual stress.

Description

technical field [0001] The invention relates to a bead steel wire rewinding and straightening device. Background technique [0002] In the traditional production process of bead wire, since the deformation of the steel wire in the mold is uneven, the uneven deformation will generate residual stress, which can generally be eliminated by tempering and roller straighteners, but sometimes The residual stress cannot be eliminated due to poor straightener or improper adjustment of the straightener, which will affect the straightness of the steel wire. In serious cases, the entire steel wire will be unusable and scrapped; in addition, during the tempering production of the bead wire, There will be poor cable quality due to equipment or human factors, which will cause customers to mess up when using it or cause disconnection due to line pressure. Contents of the invention [0003] The object of the present invention is to provide a bead wire rewinding and straightening device for...

[0002]In the traditional production process of bead wire, due to the uneven deformation of the steel wire in the mold, the uneven deformation will generate residual stress, which is generally It can be eliminated by tempering and roller straighteners, but sometimes the residual stress cannot be eliminated due to reasons such as poor straighteners or improper adjustment of the straighteners, which will affect the straightness of the steel wire, and seriously cause the entire steel wire to fail. In addition, when the bead steel wire is tempered, the quality of the cable will also be poor due to equipment or human factors, which will cause the customer to mess up when using it or cause the wire to be broken due to pressure.
