Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a steel cord water quenching device. Background Art

[0002] In the existing steel cord production process, the steel wire needs to be quenched. Due to the extremely high thermal conductivity of water, the steel wire will undergo nucleate boiling to form martensite when it comes into contact with water before the transformation is completed. In order to avoid this, AQ solution (polyacrylate) is usually used as a refrigerant to achieve non-isothermal quenching. When the steel wire enters the AQ solution, film boiling will occur, and the steel wire will be surrounded by the steam film generated by film boiling, thereby stabilizing the cooling rate of the steel wire.

[0003] The existing quenching process is that several steel wires enter the quenching tank in parallel from the dividing groove for quenching, which will cause the temperature of the AQ solution between the steel wires to be too high and even cause the AQ solution to boil, making the steam film unstable, thereby affecting the transformation of the steel wire structure and causing metallographic abnormalities, and the higher AQ solution temperature will reduce the strength of the steel wire; the immersion depth of the steel wire is one of the factors that affect the thickness of the steam film and thus the heat conduction rate. Before the steam escapes from the steam film, the pressure in the steam film must at least reach the water pressure on the steam film. The deeper the steel wire is immersed, the higher the pressure on the steam film and the thicker the steam film; the existing process for adjusting the immersion length of the steel wire in the quenching liquid is not only cumbersome, but also consumes a lot of manpower.

[0008] Furthermore, the tensioning mechanism includes a roller, which is rotatably connected to the quenching tank body, and the steel wire is arranged on the roller, and the axial direction of the roller is perpendicular to the movement direction of the steel wire.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0019] This embodiment provides a steel cord water quenching device, such as Figure 1 As shown, it includes a quenching tank body 1, and tensioning mechanisms for tensioning steel wires 2 are arranged on both sides of the top of the quenching tank body 1. The steel wires 2 cross the quenching tank body 1 through the tensioning mechanisms. The quenching tank body 1 is provided with a plurality of height adjustment mechanisms 4 on both sides of the tensioning mechanisms. The steel wires 2 are located above two relative height adjustment mechanisms 4, and the height adjustment mechanisms 4 are provided with height limiters. The steel wires 2 are synchronously raised and lowered with the height adjustment mechanisms 4 through the height limiters, so as to facilitate the adjustment of the immersion depth of the steel wires 2. The steel wires 2 are tensioned by the tensioning mechanism, and the height of the steel wires 2 is adjusted by the cooperation of the height adjustment mechanism 4 and the height limiter, so as to control the immersion depth of the steel wires 2, save manpower, facilitate the adjustment of the upper and lower staggering of adjacent steel wires 2, reduce the solution temperature between adjacent steel wires 2, stabilize the steam film on the surface of the steel wires 2, and thus improve the quality of water quenching of the steel wires 2. In this embodiment, adjacent strands of steel wires 2 are controlled by different height adjustment mechanisms 4.

[0020] In this embodiment, Figure 1 As shown, the height adjustment mechanism 4 includes a driving device 401, an inner tube 402, an outer tube 403, a fixed rod and a rotating rod. The inner tube 402 is slidably connected in the outer tube 403. The inner tube 402 and the outer tube 403 do not rotate relative to each other. The outer tube 403 is fixedly connected to the driving device 401. The top of the fixed rod is fixedly connected to the inner tube 402. The bottom of the rotating rod is transmission-connected to the driving device 401. In this embodiment, the driving device 401 includes a motor. The output end of the motor is transmission-connected to the rotating rod. The fixed rod is threadedly connected to the rotating rod. The inner tube 402 and the outer tube 403 are provided to isolate the liquid to ensure the normal operation of the height adjustment mechanism 4.

[0021] In this embodiment, Figure 1As shown, the tensioning mechanism includes a roller 3, which is rotatably connected to the quenching tank body 1. The steel wire 2 is arranged on the roller 3. The axial direction of the roller 3 is perpendicular to the movement direction of the steel wire 2. The steel wire 2 is tensioned by arranging the roller 3, and the roller 3 is rotatably connected to the quenching tank body 1, so that the steel wire 2 can slide on the roller 3 and reduce the wear of the steel wire 2. In this embodiment, the roller 3 in the tensioning mechanism can be replaced by a fixed pulley.

[0022] In this embodiment, Figure 1 As shown, the height limiting member includes a pressure roller 5, which is rotatably connected to the height adjusting mechanism 4 via a connecting rod 6. The connecting rod 6 is detachably arranged on the height adjusting mechanism 4 to facilitate the disassembly and assembly of the pressure roller 5. The steel wire 2 is pressed tightly under the pressure roller 5. The axial direction of the pressure roller 5 is perpendicular to the movement direction of the steel wire 2. The height of the steel wire 2 is limited by setting the pressure roller 5. The pressure roller 5 is rotatably connected to the height adjusting mechanism 4 to facilitate reducing the friction when the steel wire 2 is pulled and reducing the wear of the steel wire 2. In this embodiment, the pressure roller 5 in the height limiting member can be replaced by a fixed pulley.

[0023] In this embodiment, Figure 1 As shown, the roller 3 is rotatably connected to the quenching tank body 1 through the adjusting rod 7, one end of the adjusting rod 7 is hinged on the quenching tank body 1, and the other end of the adjusting rod 7 is rotatably connected to the roller 3. The setting of the adjusting rod 7 can better control the roller 3 to tension the steel wire 2.

[0024] When using the device, first place the steel wire 2 above the roller 3 on one side of the quenching tank body 1, then pass the steel wire 2 between the two opposite height adjustment mechanisms 4 on both sides of the quenching tank body 1 and the pressure rollers 5 arranged thereon, pull the steel wire 2 and place it on the roller 3 on the other side of the quenching tank body 1, connect the steel wire 2 with the external device to pull the steel wire 2, adjust the position of the water quenching of the steel wire 2, adjust the angle of the adjustment rod 7, drive the roller 3 to rotate and tighten the steel wire 2, when it is necessary to adjust the height of the steel wire 2, start the motor, and the motor drives the rotating rod connected to it to rotate. The threaded connection allows the fixed rod to move up and down when the rotating rod rotates, driving the inner tube 402 fixed thereto to slide up and down in the outer tube 403. The pressure roller 5 connected to the height adjustment mechanism 4 is rotated by the connecting rod 6 to follow the outer tube 403 to move up and down, thereby adjusting the height of the steel wire 2. By adjusting the height adjustment mechanism 4 under different steel wires 2 respectively, adjacent steel wires 2 are at different heights, making the water quenching of the steel wire 2 more stable. By adjusting the height of the height adjustment mechanism 4 on one side of the quenching tank body 1, the steel wire 2 is tilted, and the immersion depth of the steel wire 2 is adjusted more easily and conveniently.
