Abstract
Description
Steel cord water bath quenching device Technical Field
[0001] This utility model relates to the field of steel cord production technology, and more specifically to a water bath quenching device for steel cord. Background Technology
[0002] The production of steel cord involves multiple processes, including dry drawing, electroplating, wet drawing, and twisting. The stability of product quality in the electroplating process directly affects the drawing and twisting processes in the wet drawing and twisting stages. After the steel cord wire rods are dry-drawn into wires of a specified diameter, the grains of the wire are subjected to severe deformation or even breakage under external force during dry drawing, resulting in a significant decrease in mechanical properties. Therefore, before copper plating, the wire needs to absorb heat in a gas furnace to undergo austenitization transformation, followed by water bath quenching and gradual cooling to transform it into a sorbite structure. This process improves and restores the ductility of the drawn wire to meet the requirements of the wet drawing process, providing an ideal metallographic structure to ensure work hardening during wet drawing and guaranteeing that the single filaments achieve the desired tensile strength after wet drawing.
[0003] The water bath quenching process involves pumping quenching coolant from the bottom tank to the upper quenching circulation tank via a motor (pump). In the circulation tank, the coolant covers the steel wire to lower its temperature. However, the quenching and cooling of the steel wire releases a significant amount of heat. Currently, the motor (pump) above the quenching circulation tank is completely exposed to the high-temperature zone, which is detrimental to its heat dissipation and cooling.
[0004] If the motor (pump) is damaged, it will be unable to pump the coolant to the circulation tank, and the steel wire will not be cooled and submerged by the quenching liquid, affecting the structural transformation of the steel wire. This will make the steel wire difficult to draw and cause it to break. Summary of the Invention
[0005] To address the technical problems existing in the quenching of steel cord in the prior art, the first aspect of this utility model proposes a water bath quenching device for steel cord, comprising:
[0006] Quenching liquid pool, the interior of which is used to contain quenching liquid;

[0008] An electric motor is connected to the quenching circulation tank to draw quenching liquid from the quenching liquid pool into the quenching tank, so that the quenching liquid submerges the steel wire passing through the quenching tank.

[0029] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.
[0030] As shown in Figures 1 to 3, the present invention provides a technical solution for a steel cord water bath quenching device, comprising a quenching liquid pool 100, a quenching circulation tank 200, a motor 400, the aforementioned steel cord water bath quenching device, and a collection tank 500.
[0031] The interior of the quenching liquid pool 100 is used to contain the quenching liquid, and the quenching circulation tank 200 is located above the quenching liquid pool 100. The quenching circulation tank 200 is provided with multiple quenching grooves 210 for steel wires to pass through.
[0032] Furthermore, the motor 400 is connected to the quenching circulation tank 200 to draw quenching liquid from the quenching liquid pool 100 into the quenching tank 210, so that the quenching liquid submerges the steel wire passing through the quenching tank 210.
[0033] The collection tank 500 is located above the quenching circulation tank 200 and is used to collect the hot steam generated during quenching.
[0034] The heat insulation cover 300 is placed over the outside of the motor 400 to prevent the heat generated during quenching from directly contacting the motor 400, thus forming a thermal barrier around the motor 400.
[0035] Furthermore, the heat insulation cover 300 is positioned above the quenching circulation tank 200 when the motor 400 is operating.
[0036] As shown in Figure 1, since the motor 400 is located above the quenching circulation tank 200, when the steel wire is quenched in the water bath, the hot steam continuously moves upward to form a heat wave. In order to provide the motor 400 with a relatively low operating environment, the heat insulation cover 300 is placed on the outside of the motor 400 to prevent the heat wave from hitting the motor 400 and to form a heat shield. The heat wave will be collected and extracted by the collection tank 500.
[0037] As shown in Figure 3, the heat insulation cover 300 is provided with a heat insulation cavity 301 for accommodating the motor 400, and the opening of the heat insulation cavity 301 faces the outside of the quenching circulation tank 200.
[0038] Since heat moves upward from the inside of the quenching circulation tank 200, the opening of the heat insulation cavity 301 faces the outside of the quenching circulation tank 200. The purpose is to form a thermal barrier in the direction of the motor 400 toward the quenching circulation tank 200. Since there is no heat source on the outside, it does not need to be covered. At the same time, the opening can also play a role in heat dissipation through air convection.
[0039] As shown in Figures 4 to 6, the heat insulation cover 300 includes a cover body 310, a connecting plate 320, and a connecting part 330.
[0040] Among them, a heat insulation cavity 301 is formed on the inner side of the main body 310 of the cover.
[0041] In an optional embodiment, the main body 310 of the cover is formed by splicing together heat insulation panels 311.
[0042] Furthermore, the connecting plate 320 is connected to the upper part of the cover body 310, and the first side surface of the connecting plate 320 is provided with a handle 321. The connecting part 330 is located at the upper end of the connecting plate 320 and is used to connect to the edge of the collection tank 500.
[0043] Thus, when the motor 400 is not in operation, the heat insulation cover 300 can be disassembled at any time. Once the production line is running, the heat insulation cover 300 can be lifted by the handle 321, covering the motor 400 with the cover body 310. At this time, the bottom of the cover body 310 rests on the upper surface of the quenching circulation tank 200, and the connecting part 330 is hung in the groove of the outer frame of the collecting tank 500. This is simple and efficient for workers, and achieves the purpose of protecting the motor 400.
[0044] In an optional embodiment, the heat insulation cavity 301 has a cubic structure. Optionally, the main body 310 of the cover includes four heat insulation plates 311, all of which are rectangular and form three sides and the top surface of the cubic structure.
[0045] Furthermore, the heat insulation board 311 includes a double-layer board and a cavity 302 between the double-layer board, and the cavity 302 is provided with a heat insulation layer.
[0046] Specifically, the insulation layer can be a porous insulation structure, such as insulation cotton board, insulation foam board, etc.
[0047] In the above embodiment, the connecting plate 320 is perpendicular to the top surface of the cover body 310. Preferably, to avoid thermal deformation of the connecting plate 320, a side plate 322 is provided between the connecting plate 320 and the top surface of the cover body 310. The first edge of the side plate 322 is in contact with the connecting plate 320, and the second edge of the side plate 322 is in contact with the top surface of the cover body 310.
[0048] Thus, the structural strength of the connecting plate 320 is improved by the support of the side plate 322.
[0049] As shown in Figures 2 and 5, the connecting portion 330 is configured to have a hook, and the bending direction of the hook is towards the second side of the connecting plate 320.
[0050] Thus, the hook can be used to connect with the edge of the collection tank 500.
[0051] In conjunction with the above embodiments, the motor heat insulation device proposed in this application has a simple structure, is easy to remove from and put into the quenching production process, and has good flexibility. When the motor heat insulation device is placed on the outside of the motor, it can effectively form a thermal barrier for the motor, preventing the heat generated by quenching from directly affecting the operation of the motor, thereby extending the service life of the motor, reducing the failure rate, reducing the risk of quenching interruption, effectively reducing wire breakage, and improving the yield.
[0052] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
