Abstract
Description
Technical Field
[0001] This utility model belongs to the field of processing equipment for tire bead wire, and specifically relates to a boron coating device for wire. Background Technology
[0002] Bead wires are a crucial component of automobile tires, bearing the vehicle's overall weight and various external impacts. To enhance the durability and safety of these wires, engineers apply a boron coating to improve their hardness, strength, and corrosion resistance. Existing boron coating equipment is relatively simple, directly passing the wires through a tank containing a borax mixture. This method results in poor coating quality and uneven boron application. Utility Model Content
[0003] Based on the content in the background art, this utility model provides a boron coating device for steel wire, which can continuously circulate the borax mixture to improve the boron coating quality of the steel wire.
[0004] A boron coating device for steel wire is disclosed. The main body of the device is divided into a first boron coating chamber, a second boron coating chamber, a liquid inlet chamber, and a circulation chamber by a partition. The first boron coating chamber, the second boron coating chamber, and the liquid inlet chamber are located above the circulation chamber. The liquid inlet chamber is located between the first boron coating chamber and the second boron coating chamber. The liquid inlet chamber has through holes on both sides to connect its interior with the interior of the first boron coating chamber and the interior of the second boron coating chamber, respectively. The bottom surface of the liquid inlet chamber has a lifting through hole to connect its interior with the interior of the circulation chamber. A lifting pump is fixedly installed on the top surface of the liquid inlet chamber. The long shaft of the lifting pump passes through the lifting through hole and extends into the circulation chamber, which can lift the liquid in the circulation chamber to the liquid inlet chamber. Then, the borax mixture flows from the liquid inlet chamber to both sides simultaneously into the first boron coating chamber and the second boron coating chamber.
[0005] Overflow chambers are respectively provided on the outer sides of the first and second boron coating chambers. The side plate of the first boron coating chamber has a through hole connecting its interior to the corresponding overflow chamber, and the side plate of the second boron coating chamber also has a through hole connecting its interior to the corresponding overflow chamber. An overflow pipe is provided in each overflow chamber, connecting its interior to the circulation chamber. When the liquid level in the overflow chamber exceeds the height of the overflow pipe, the borax mixture can flow back into the circulation chamber for recirculation. The continuously circulating borax mixture prevents sedimentation and ensures uniform density. Wire-passing holes are located on the outer surface of each overflow chamber, allowing the steel wire to pass sequentially through the left overflow chamber, the first boron coating chamber, the liquid-filling chamber, the second boron coating chamber, and the right overflow chamber. The borax mixture flowing in the first and second boron coating chambers can more evenly coat the steel wire surface, improving the boron coating quality.
[0006] Furthermore, a residual liquid collection chamber is also provided next to the overflow chamber, which is located above the circulation chamber. The residual liquid collection chamber also has a wire threading hole on its side and a mesh opening on its bottom surface to connect its interior with the circulation chamber. When the steel wire comes out of the wire threading hole in the overflow chamber and enters the residual liquid collection chamber, the excess borax mixture dripping from the surface of the steel wire can re-enter the circulation chamber through the mesh opening on the bottom surface of the residual liquid collection chamber for recycling.
[0007] Furthermore, a liquid addition pipe is connected to the side of the circulation chamber, through which the initial borax mixture is added into the circulation chamber. A discharge pipe is connected to the bottom of the circulation chamber, and a ball valve is installed on the discharge pipe to facilitate the drainage of the circulation chamber and the replacement of the new borax mixture.
[0008] Furthermore, the circulating chamber is also equipped with a heating coil, which can maintain the temperature of the borax mixture at around 90°C through continuous heating.
[0009] Through the above technical solutions, this utility model has at least the following beneficial effects:
[0010] The boron coating device for steel wire described in this application uses a booster pump to lift the borax mixture in the circulation chamber to the upper liquid chamber, and then simultaneously flow into the first and second boron coating chambers on both sides. Finally, it flows back into the circulation chamber from the overflow chamber for recirculation. In this way, when the steel wire passes through the first and second boron coating chambers for boron coating, the borax mixture is constantly flowing and circulating, which makes the density of the borax mixture uniform and avoids sedimentation. The flowing borax mixture can be more evenly coated on the surface of the steel wire, improving the boron coating quality of the steel wire. Attached Figure Description
