Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to a bidirectional adjusting groove for quenching 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 that the single filaments achieve the desired tensile strength after wet drawing.

[0003] Adjusting the strength of the steel wire in the electroplating process is particularly important. It is generally achieved through a two-stage water bath. The first stage is called the first water bath stage, and the second stage is called the second water bath stage. The area between the first and second stages is air-cooled, or simply air-cooled. Generally, shortening the length of the first water bath stage, shortening the length of the air-cooled stage, and lengthening the length of the second water bath stage will increase the strength, and vice versa.

[0004] For example, the multi-functional water quenching tank for a large-specification hose steel wire electroplating line proposed in publication CN203128629U uses a water bath quenching length device with equally spaced partitions, adjustable at one end. The water bath quenching length is adjusted by changing the position of the baffle plate within the equally spaced positioning plates. Due to the bayonet design, the baffle plate must be lifted before adjustment, causing the steel wire to detach from the quenching liquid, resulting in abnormal microstructure and breaking strength of the steel wire. Summary of the Invention

[0005] To address the technical problems existing in the quenching of steel cord in the prior art, this utility model proposes a bidirectional adjusting groove for quenching steel cord, comprising:

[0006] The tank has a first liquid storage space and a second liquid storage space inside. The first liquid storage space and the second liquid storage space are connected through an overflow port. A partition is provided above the second liquid storage space. A plurality of parallel vertical plates are provided above the partition, so that the area above the partition is divided into multiple water bath areas.

[0007] A pumping component is connected to the tank and is used to pump quenching liquid into the first liquid storage space, so that the quenching liquid enters the second liquid storage space from the first liquid storage space through the overflow port. The partition plate is provided with an opening area, and the opening area is connected to the water bath area.

[0008] A pair of movable plates are connected to the water bath area, forming a quenching area between the pair of movable plates;

[0009] A lead screw is connected to the movable plate;

[0010] The lead screw is configured to be operable to rotate about its axis and drive the movable plate to move along the axis of the lead screw, thereby changing the length and position of the quenching zone.

[0011] Preferably, the lead screw includes a first lead screw and a second lead screw, and a rotating seat is provided on the partition plate. The first lead screw and the second lead screw are rotatably connected to the rotating seat, and the first lead screw and the second lead screw can rotate independently.

[0012] Preferably, the movable plate includes a first movable plate and a second movable plate, the first lead screw is connected to the first movable plate, and the second lead screw is connected to the second movable plate.

[0013] Preferably, the movable plate is configured such that the thickness of the bottom is greater than the thickness of the top, and the two sides of the movable plate are in contact with the two sides of the water bath area.

[0014] Preferably, an overflow plate is provided above the partition, and one end of the lead screw is rotatably connected to the overflow plate and extends outward through the overflow plate.

[0015] Preferably, a nut is provided at one end of the lead screw that passes through the overflow plate.

[0016] Preferably, a line-supporting roller is provided above the overflow plate, and the height of the line-supporting roller is flush with the upper edge of the movable plate.

[0017] Preferably, the pumping component includes a motor, a lifting cylinder, and lifting blades. The lifting cylinder passes through the first liquid storage space, and the outlet of the lifting cylinder is located within the first liquid storage space. The motor drives the lifting blades to draw quenching liquid from the bottom of the lifting cylinder into the first liquid storage space.

[0018] Preferably, the first end of the trough is provided with a first roller, and the second end of the trough is provided with a second roller.

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

[0020] The movable plate in this application can move freely and parallel within the water bath quenching tank. During adjustment, the steel wire will not detach from the quenching liquid, thus avoiding the steel wire detaching from the quenching liquid due to the lifting of the quenching liquid baffle plate during the adjustment of the water bath quenching length, which would cause abnormal microstructure and unqualified strength indicators of the steel wire, thereby improving the quenching quality of the steel wire.

[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 As shown, this utility model proposes a bidirectional adjusting groove for quenching steel cord, which is used to complete the second end water bath quenching of the steel wire. The bidirectional adjusting groove includes a groove body 100, a pump component 200, a pair of movable plates 310 and a lead screw 320.

[0028] The tank 100 is installed in the quenching liquid container tank. The first end of the tank 100 is provided with a first roller 104, and the second end of the tank 100 is provided with a second roller 105. The tank 100 can move along the length of the quenching liquid container tank by means of the first roller 104 and the second roller 105.

[0029] like Figure 2 As shown, the tank 100 is provided with a first liquid storage space 101 and a second liquid storage space 102. The first liquid storage space 101 and the second liquid storage space 102 are connected through an overflow port 103. A partition 110 is provided above the second liquid storage space 102. A plurality of parallel vertical plates 120 are provided above the partition 110, so that the area above the partition 110 is divided into a plurality of water bath areas 140.

[0030] In this way, multiple independent water bath zones 104 can treat steel wires with different processes in a water bath without interfering with each other.

[0031] Furthermore, the pumping component 200 is connected to the tank 100 and is used to pump quenching liquid into the first storage space 101.

[0032] Optionally, the pump component 200 includes a motor 210, a lifting cylinder 220, and a lifting blade 230. The lifting cylinder 220 passes through the first liquid storage space 101, and the outlet 221 of the lifting cylinder 220 is located within the first liquid storage space 101.

[0033] The motor 210 is used to drive the lifting blade 230 and draw quenching liquid from the bottom of the lifting cylinder 220 into the first liquid storage space 101.

[0034] Specifically, when the pumping component 200 draws quenching liquid, the quenching liquid enters the second storage space 102 from the first storage space 101 through the overflow port 103. The partition plate 110 is provided with an opening area 111, which is connected to the water bath area 140.

[0035] Thus, when the quenching fluid enters the second storage space 102, as the liquid level gradually rises, it can surge from the opening area 111 to the water bath area 140.

[0036] Furthermore, a pair of movable plates 310 are connected to the water bath area 140, forming a quenching area 301 between the pair of movable plates 310.

[0037] Thus, through the limiting effect of a pair of movable plates 310, the quenching liquid flowing up from the opening area 111 is constrained and limited, so that the quenching liquid can only gradually rise within the space limited by the pair of movable plates 310, and submerge the steel wire passing above the movable plates 310 to achieve water bath quenching.

[0038] Furthermore, the lead screw 320 is connected to the movable plate 310, wherein the lead screw 320 is configured to be operable to rotate about its axis and drive the movable plate 310 to move along the axial direction of the lead screw 320, thereby changing the length and position of the quenching zone 301.

[0039] Thus, the position of the movable plate 310 changes as the lead screw 320 rotates. This adjustment method allows the position of the movable plate 310 to change infinitely, enabling more precise positioning of the distance between the two movable plates 310. At the same time, the quenching liquid will not leak during the adjustment process, and the steel wire will always be submerged and covered by the quenching liquid.

[0040] Optionally, the lead screw 320 includes a first lead screw and a second lead screw, and a rotating seat 330 is provided on the partition plate 110. The first lead screw and the second lead screw are rotatably connected to the rotating seat 330, and the first lead screw and the second lead screw can rotate independently.

[0041] Furthermore, the movable plate 310 includes a first movable plate 311 and a second movable plate 312, with a first lead screw connected to the first movable plate 311 and a second lead screw connected to the second movable plate 312.

[0042] Thus, by adjusting the rotation of the first lead screw or the second lead screw individually, the positions of the first movable plate 311 and the second movable plate 312 can be adjusted independently. This not only changes the length of the quenching area 301 formed between the first movable plate 311 and the second movable plate 312, but also changes the position of the quenching area 301 formed between the first movable plate 311 and the second movable plate 312, thereby changing the length and position of the steel wire quenching.

[0043] Furthermore, the movable plate 310 is configured such that the thickness at the bottom is greater than the thickness at the top, and the two sides of the movable plate 310 are attached to the two sides of the water bath area 140.

[0044] In this way, deformation of the movable plate 310 due to the heat of the quenching liquid can be avoided, and the two sides of the movable plate 310 can be kept in contact with the two sides of the water bath area 140.

[0045] Furthermore, an overflow plate 130 is provided above the partition 110, and one end of the lead screw 320 is rotatably connected to the overflow plate 130 and extends outward through the overflow plate 130.

[0046] In this way, the quenching liquid overflowing from the movable plate 310 can flow out from the overflow hole on the overflow plate 130, so that the outer side of the movable plate 310 will not be submerged by the quenching liquid.

[0047] Optionally, a nut 321 is provided at one end of the lead screw 320 that passes through the overflow plate 130. In this way, by turning the nut 321 with a tool, the rotation of the lead screw 320 can be controlled, and the position of the movable plate 310 can be adjusted.

[0048] In the above embodiment, a wire support roller 131 is provided above the overflow plate 130, and the height of the wire support roller 131 is flush with the height of the upper edge of the movable plate 310.

[0049] Thus, when the steel wire passes through the trough 100, it is supported by the wire support rollers 131 on both sides. When it reaches the overflow plate 130, it is submerged and quenched by the quenching liquid surging up from the opening area 111.

[0050] In conjunction with the above embodiments, the movable plate in this application can move freely and parallel within the water bath quenching tank. During adjustment, the steel wire will not detach from the quenching liquid, preventing the steel wire from detaching from the quenching liquid due to the lifting of the baffle plate during the adjustment of the water bath quenching length. This avoids abnormal microstructure and substandard strength indicators in the steel wire, thus improving the quenching quality of the steel wire. Furthermore, the operator only needs to stand beside the water bath quenching tank and use tools to remotely adjust the position of the baffle plate in the quenching liquid without obstructing their view. Precise adjustments are possible, and safety hazards such as burns from high temperatures are avoided. The distance of the quenching liquid covering the steel wire of any length can be freely adjusted to regulate the steel wire's performance indicators.

[0051] 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.
