Embodiment 1

[0028] Such as figure 1 As shown, this patent is realized in this way: the steel wire 2 enters the lead liquid in the quenching tank body 1, and passes through a group of pressing rollers 3, and then completes the tempering operation to the bead steel wire. The tempering device is divided into three zones, and each zone has an independent thermocouple 4 for temperature measurement. By transmitting the collected temperature signal to the programmable controller, the programmable controller drives the electric heating tube 5 to complete the tempering according to the set parameters. Warming of the medium.

[0029] After the steel wire 2 is treated by the tempering device, the strength dispersion of the steel wire is less than 20 mpa, and the yield strength specific dispersion of the steel wire can be controlled within 1%.

Embodiment 2

[0031] On the basis of the above examples, if figure 1 As shown, a bead wire tempering device includes a trapezoidal inner hollow tank body 1, wherein the tank body 1 is stainless steel with heat-insulating asbestos in the middle of a double-layer structure, that is, the material is stainless steel, and the middle layer is an insulation layer. Thermal insulation asbestos, the outer layer is also made of stainless steel, with a trapezoidal design, which can reduce lead liquid by 20%, saving costs. In addition, after the tempering treatment is completed, when the steel wire leaves the tank body 1, the trapezoidal structure design is adopted, so that the residual lead liquid on the surface of the steel wire can slide down naturally, so as not to adhere to the surface of the steel wire and affect the product quality. A pressure roller 3 is arranged symmetrically at both ends of the tank body 1 , and lead liquid is arranged in the tank body 1 .

[0032] Preferably, the pressure ro...

Embodiment 3

[0038] On the basis of the above embodiments, the present invention provides a bead wire tempering method, which includes the following steps:

[0039] A: Lead liquid is placed in the hollow tank inside the trapezoid;

[0040] B: The thermocouple detects the temperature and transmits the collected temperature signal to the programmable controller;

[0041] C: The programmable controller drives the electric heating tube to complete the heating of the tempering medium;

[0042] D: The steel wire passes through the bottom of the pressure rollers installed at both ends of the tank body to complete tempering.

[0043] The method, wherein, step B1 is also performed after performing step B: when the temperature value detected by the thermocouple is lower than the set temperature value, the programmable controller gives a heating drive signal, and when the detected temperature reaches the set temperature value When the value is set, the programmable controller will give a drive sign...

Abstract

The invention relates to a tire bead wire tempering device which comprises a trapezoidal hollow tank body, wherein the tank body is made of stainless steel with heat insulation asbestos arranged at the middle of a dual-layer structure, two inner ends of the tank body are symmetrically provided with compression rollers, and molten lead is arranged in the tank body. A tire bead wire tempering device comprises the following steps of: A, placing the molten lead in the trapezoidal hollow tank body; B, detecting a temperature by a thermocouple, and transmitting the acquired temperature signal to a programmable controller; C, driving an electrical heated tube by the programmable controller for completing the heating of a tempering medium; and D, tempering a steel wire below the compression rollers on two ends in the tank body. By adopting the technical scheme provided by the invention, the strength windage of the steel wire treated by the tempering device is less than 20mpa, and the yield ratio windage of the steel wire can be controlled within 1 percent.

Description

technical field [0001] The invention relates to the technical field of bead wire production equipment, in particular to a bead wire continuous tempering device and a tempering method. Background technique [0002] In the production process of bead wire, it needs to go through four processes of rough drawing, heat treatment, fine drawing and tempering copper plating. With the increase of the deformation of the steel wire during drawing, the broken grains will cause work hardening, and the residual stress inside the steel wire will also appear. Therefore, it is necessary to use a tempering device to temper the bead steel wire, that is, the structure Recrystallization or recovery, good plasticity index can be obtained on the basis of original work hardening. [0003] In the traditional production process, the temperature of the tempering device is adjusted manually, which is not only labor-intensive, but also has poor control accuracy, which affects the performance of the prod...
