Description

Technical Field

[0001] This invention relates to the field of tire bead wire production technology, and in particular to a heat treatment apparatus for tire bead wire production. Background Technology

[0002] Bead wires play a crucial role in tire safety, high-speed performance, and durability. During the production process, bead wires undergo heat treatment to ensure they possess high strength, good elongation, torsion, and bending properties, thereby improving tire quality and ultimately enhancing tire safety.

[0003] In the quenching process of tire bead wire, for example, application number CN201210480222.9 discloses a device for heat treatment water bath quenching of tire bead wire, including a tank, a first-stage water bath working tank and a last-stage water bath working tank set in the tank, used for heat treatment water bath quenching of tire bead wire. In this device, the steel wire is cooled by quenching liquid. During the circulation of the quenching liquid, the quenching liquid contains fine steel chips that fall off during the quenching of the steel wire. The steel chips are not only detrimental to the surface forming quality of the steel wire, but also easily cause sedimentation and blockage of the circulation pipe, thus affecting the operation of the quenching liquid circulation system. During the quenching process of the steel wire, a large amount of high-temperature water vapor is generated, which can easily cause burns to the operators. Traditionally, the high-temperature water vapor is usually directly discharged, resulting in waste of water. In the quenching equipment, the high-temperature steel wire is transported by guide rollers. The guide rollers are in contact with the steel wire for a long time, and their temperature rises, which can easily cause thermal corrosion with the steel wire, thus affecting the production quality of the steel wire.

[0011] Furthermore, one of the tap ports of the four-way valve is connected to a third liquid guide pipe, and the other end of the third liquid guide pipe is connected to one end of the spray pipe.

The quenching workbench 1 is located on top of the machine control box 4, which is located on top of the liquid storage tank 5. The liquid storage tank 5 stores quenching liquid. The cooling box 3 is located on one side of the liquid storage tank 5. The quenching workbench 1 has multiple quenching tanks 101 separated by partitions. Each quenching tank 101 has a liquid outlet 9031 at the bottom of one side. The liquid storage tank 5 has a return port on one side. The second liquid pump 9 is connected to the pumping end, and the pumping end of the second liquid pump 9 is connected to the return pipe 901. The upper end of the return pipe 901 is connected to the four-way valve 902. One of the branch ports of the four-way valve 902 is connected to the first guide pipe 903. The branch ends of the first guide pipe 903 are connected to each outlet nozzle 9031. Under the operation of the second liquid pump 9, the quenching liquid stored in the storage tank 5 is drawn to one end of the quenching tank 101 for flow, thereby immersing and quenching the steel wire 11 passing through the quenching tank 101.

[0029] It is worth mentioning that, such as Figure 6 As shown, a steel wire 11 is arranged separately in the quenching tank 101, and the bottom of the quenching tank 101 is set at an inclination of 15°.

[0030] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: the present invention sets the quenching tank 101 as an inclined flow channel, which enables the quenching liquid to flow effectively in the quenching tank 101, effectively avoiding the quenching effect from the sudden increase in quenching temperature.

Under the operation of the second liquid pump 9, the quenching liquid stored in the storage tank 5 is drawn into the interior of the roller shaft body 201, and then distributed from the roller shaft body 201 to the interior of each guide wheel 202. The quenching liquid flows out from the water outlet holes 203 on the guide wheel 202 to cool and reduce the temperature of the guide wheel 202 and the guided steel wire 11.

[0032] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: By setting up an industrial flow channel system for each guide wheel 202 in the guide roller 2, the present invention can cool and reduce the temperature of the guide wheel 202 and the guided steel wire 11 by allowing quenching liquid to flow out from the water outlet 203 on the guide wheel 202, thereby preventing thermal erosion.

The other end of the third liquid guide pipe 905 is connected to one end of the spray pipe 10. Under the operation of the second liquid pump 9, the quenching liquid stored in the liquid storage tank 5 is drawn into the interior of the spray pipe 10. The nozzles 1001 at the bottom of the spray pipe 10 spray and wash the steel wire 11 transported in the corresponding quenching tank 101.

[0034] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: the present invention sprays and washes the steel wires 11 transported in the corresponding quenching tanks 101 through the nozzles 1001 at the bottom of the spray pipe 10, which can clean the fine steel chips remaining on the surface of the steel wires 11 after quenching and ensure the surface quality of the steel wires 11.

A liquid guiding slope 1021 is provided at the bottom of the connection between the filter tank 102 and the quenching workbench 1. A filter cotton layer 1022 is provided in the middle of the filter tank 102. The filter cotton layer 1022 filters the steel chips carried in the quenching liquid. The filtered quenching liquid is introduced into the top of the cooling box 3. A cooling air vent is provided on one side of the top of the cooling box 3. A refrigeration box 7 is provided close to the outer end of the cooling air vent. A heat dissipation fan 701 is provided on the outside of the refrigeration box 7.

The bottom of the cooling tank 3 and the side near the liquid storage tank 5 are provided with a drain port, and the outer end of the drain port is connected to the liquid drawing end of the first liquid pump 8. The drain end of the first liquid pump 8 is connected to the liquid replenishment port provided at the bottom of the side of the liquid storage tank 5. The first liquid pump 8 returns the cooled quenching liquid to the liquid storage tank 5 for recycling.

[0036] It is worth mentioning that the lower end of the filter tank 102 is provided with a hydrophobic plate 1023, which causes the quenching liquid to drip in the form of water droplets, thereby improving the cooling efficiency of the quenching liquid.

[0037] The top of the quenching workbench 1 is covered with a top cover 6. An exhaust pump 601 is provided on one side of the top cover 6. An exhaust pipe 602 is connected to the outer port of the exhaust pump 601, and the other end of the exhaust pipe 602 extends to the top of the inner cavity of the cooling box 3.

[0038] It is worth mentioning that the exhaust pipe 602 is connected to a heat exchange tube 603 at the top of the inner cavity of the cooling box 3. The heat exchange tube 603 includes a distribution ring pipe 6031, and several heat exchange capillary tubes 6032 are connected to the bottom of the distribution ring pipe 6031. The quenching liquid dripping from the top of the cooling box 3 and the cold air blown in by the heat dissipation fan 701 combine with the heat exchange capillary tubes 6032 for heat exchange, so that the high temperature steam condenses into water inside the heat exchange capillary tubes 6032. Then the water is discharged into the cooling box 3 from the lower end of the heat exchange capillary tubes 6032, thus avoiding the waste of water resources.

[0039] It is worth mentioning that multiple heat exchange tubes 6032 are arranged in a ring array along the axis of the split ring tube 6031, and the bottom of the multiple split ring tubes 6031 is bent inward to form a conical constriction, which increases the heat exchange surface and ensures the heat exchange effect.
