Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to a quenching device for electroplating 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 forces 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 the desired tensile strength of the single filament after wet drawing.

[0003] For example, the multi-functional water quenching tank for a large-specification hose steel wire electroplating line proposed in CN203128629U uses equidistant positioning plates in conjunction with bayonet-type liquid baffles. The side of the liquid baffle is also installed by insertion. However, long-term high temperature can easily cause deformation, creating gaps between the bottom of the side baffle and the cooling working tank. This causes the quenching liquid to flow to both sides, preventing the steel wire from being completely submerged, thus reducing the quenching quality. Summary of the Invention

[0004] To address the technical problems existing in the steel cord quenching devices of the present invention, a quenching device for steel cord electroplating is proposed, comprising:

[0005] A quenching tank is connected to a quenching liquid pool. The interior of the quenching tank is provided with a cavity, and a partition is provided above the cavity. The partition is provided with openings.

[0006] The pumping component is connected to the quenching tank and is used to draw quenching liquid from the quenching liquid pool and pump it into the cavity, and then allow it to flow up through the opening to the top of the partition.

[0007] A vertical baffle is connected above the partition, dividing the area above the partition into multiple independent quenching zones;

[0008] Movable baffles are provided between adjacent vertical baffles;

[0009] A driving component is used to drive the movable baffle to move along the length direction of the vertical baffle;

[0010] A fixed baffle is attached to the partition.

[0011] The movable baffle and the fixed baffle form a flooding area, which can be flooded by the quenching liquid flowing up from the opening when the steel wire passes over the movable baffle and the fixed baffle.

[0012] Preferably, the vertical baffle includes a base and an insert plate. The base is welded and fixed to the partition. A slot is provided above the base, and the insert plate is installed into the slot.

[0013] Preferably, the movable baffle is configured to include a first part and a second part, the thickness of the first part being greater than the thickness of the second part, the first part being located below the second part, and the bottom of the first part being provided with a slot that is adapted to the contour of the base and the insert plate.

[0014] Preferably, the thickness of the first part is more than three times the thickness of the second part.

[0015] Preferably, the driving component includes a first screw, which is threadedly connected to the movable baffle. When the first screw is operated to drive around its axis, the movable baffle moves along the axial direction of the first screw, causing the distance between the movable baffle and the fixed baffle to change.

[0016] Preferably, the first end of the first screw is connected to the rotating base, and the second end is provided with a nut, wherein the rotating base is fixed to the partition plate.

[0017] Preferably, the partition plate is provided with a support frame, the support frame is connected to a second screw, the partition plate is provided with a first screw, the second screw is meshed with the first screw through a bevel gear set, and the upper end of the second screw is provided with a nut.

[0018] Preferably, the pumping component includes a motor, a lifting cylinder, and lifting blades. The lifting cylinder is connected to the quenching tank, and the motor drives the lifting blades to draw quenching liquid from the quenching liquid pool and pump it into the cavity.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] The movable baffle of this utility model is designed to change position as the screw rotates, and always remains in contact with the vertical baffles on both sides during the movement to avoid leakage. At the same time, the movable baffle is reinforced, which not only makes the threaded transmission more reliable, but also avoids the adverse phenomenon of thermal deformation. This allows users to accurately control the position of the movable baffle in a safer, more effective and reliable way, and to control the length of the water bath section and the air cooling section for steel wire quenching.

[0026] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0027] Combination Figure 1 and Figure 2 As shown, this utility model proposes a quenching device for electroplating steel cord, including a quenching tank 10, a pumping component 20, a vertical baffle 30, a driving component 40, a movable baffle 50, and a fixed baffle 60.

[0028] The quenching tank 10 is connected to the quenching liquid pool 100. The interior of the quenching tank 10 is provided with a cavity 101. A partition 11 is provided above the cavity 101, and an opening 12 is provided on the partition 11. The pumping unit 20 is connected to the quenching tank 10 and is used to draw quenching liquid from the quenching liquid pool 100 and pump it into the cavity 101, and then allow it to flow up through the opening 12 to the top of the partition 11.

[0029] Thus, through the lifting action of the pumping component 20, the quenching liquid in the quenching liquid pool 100 can be pumped to the top of the partition plate 11 through the opening 12.

[0030] Optional, such as Figure 2 As shown, the pumping component 20 includes a motor 21, a lifting cylinder 22, and a lifting blade 23. The lifting cylinder 22 is connected to the quenching tank 10. Thus, the motor 21 drives the lifting blade 23 to draw quenching liquid from the quenching liquid pool 100 and pump it into the cavity 101.

[0031] Furthermore, the vertical baffle 30 is connected above the partition 11, dividing the area above the partition 11 into multiple independent quenching zones.

[0032] In this way, the multiple quenching zones formed are independent of each other and can be used to quench steel wires with various process requirements.

[0033] Furthermore, the movable baffle 50 is disposed between adjacent vertical baffles 30, the driving component 40 is used to drive the movable baffle 50 to move along the length direction of the vertical baffle 30, and the fixed baffle 60 is fixed to the partition 11.

[0034] The movable baffle 50 and the fixed baffle 60 form a flooding area 102, which can be flooded by the quenching liquid flowing up from the opening 12 when the steel wire passes over the movable baffle 50 and the fixed baffle 60.

[0035] Thus, the movable baffle 50, in conjunction with the driving component 40, can adjust the distance between itself and the fixed baffle 60. Throughout the adjustment process, the movable baffle 50 remains in contact with the vertical baffles 30 on both sides, preventing leakage of the quenching fluid.

[0036] Furthermore, the vertical baffle 30 includes a base 31 and an insert plate 32. The base 31 is welded and fixed to the partition 11. A slot is provided above the base 31, and the insert plate 32 is installed into the slot.

[0037] Thus, by increasing the thickness of the vertical baffle 30, deformation of the vertical baffle 30 due to long-term heat from the quenching liquid can be avoided.

[0038] Combination Figure 3 As shown, the movable baffle 50 is configured to include a first part 51 and a second part 52. The thickness of the first part 51 is greater than the thickness of the second part 52. The first part 51 is located below the second part 52. The bottom of the first part 51 is provided with a slot 53, which is adapted to the contours of the base 31 and the insert plate 32.

[0039] Thus, by increasing the thickness of the movable baffle 50, especially the thickness of the lower part, deformation of the movable baffle 50 can be avoided. At the same time, since the lower groove 53 of the movable baffle 50 cooperates with the stepped surface formed by the base 31 and the insert plate 32, the sealing performance can be further improved, and the rapid leakage of quenching liquid can be avoided.

[0040] Preferably, the thickness of the first part 51 is more than three times the thickness of the second part 52.

[0041] Combination Figure 4 As shown, the driving component 40 includes a first screw 43, which is threadedly connected to a movable baffle 50. When the first screw 43 is operated to drive around its axis, the movable baffle 50 moves along the axial direction of the first screw 43, causing the distance between the movable baffle 50 and the fixed baffle 60 to change.

[0042] Specifically, the operator rotates the first screw 43 to move the movable baffle 50 along the axis of the first screw 43, thereby controlling the length of the water bath section 120 formed between the movable baffle 50 and the fixed baffle 60, and also changing the length of the air-cooled section 103 on the other side of the movable baffle 50.

[0043] In an alternative embodiment, the first end of the first screw 43 is connected to the rotating seat 46, and the second end is provided with a nut, and the rotating seat 46 is fixed to the partition plate 11.

[0044] Thus, the rotation of the first screw 43 can be controlled by rotating the nut at one end of the first screw 43.

[0045] In a preferred embodiment, a support frame 41 is provided on the partition 11, a second screw 42 is connected to the support frame 41, a first screw 43 is provided on the partition 11, the second screw 42 and the first screw 43 are connected by a bevel gear set, and a nut 45 is provided at the upper end of the second screw 42.

[0046] Thus, by controlling the rotation of the nut 45 above the support frame 41, the rotation of the first screw 43 can be controlled, thereby changing the position of the movable baffle 50.

[0047] In conjunction with the above embodiments, the movable baffle of this utility model is designed to change position as the screw rotates, and always remains in contact with the vertical baffles on both sides during the movement to avoid leakage. At the same time, the movable baffle is reinforced, which not only makes the threaded transmission more reliable, but also avoids the adverse phenomenon of thermal deformation. This allows users to accurately control the position of the movable baffle in a safer, more effective and reliable way, and to control the length of the water bath section and the air cooling section for steel wire quenching.

[0048] 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.
