Description

Technical Field

[0001] The present application relates to the technical field of cooling equipment, and in particular to an adjustable cooling device for quenching steel cylinders. Background Art

[0002] The production process of steel cylinders usually requires steps such as material selection, quenching, grinding, stretching, closing, and painting.

[0003] In the related art, the heated steel cylinder needs to be cooled during the quenching process. In existing factories, multiple water outlets are usually opened on the water pipe, and then water is discharged through the multiple water outlets on the water pipe to spray and cool the steel cylinder.

[0004] However, in the above technology, when water is sprayed out from the water outlet and then divergently sprayed onto the cylinder, the spray water flow rate near the center of the water outlet is inconsistent with the water flow rate on both sides, which can easily lead to different cooling effects at different parts of the cylinder, causing the strength of different positions of the cylinder to deviate, thereby reducing the quenching quality of the cylinder. Summary of the Invention

[0005] In order to achieve uniform cooling of the steel cylinder and ensure the quenching effect of the steel cylinder, the present application provides an adjustable cooling device for quenching the steel cylinder.

[0006] The present application provides an adjustable cooling device for quenching steel cylinders, which adopts the following technical solutions:

[0007] An adjustable cooling device for quenching a steel cylinder comprises a frame, on which two bearing rollers are rotatably provided, the two bearing rollers being axially parallel and located at the same height, the steel cylinder being placed on the two bearing rollers, and a cooling mechanism for cooling the steel cylinder being provided on the frame, the cooling mechanism comprising:

[0008] A cooling pipe is provided on the frame and above the steel cylinder. The cooling pipe is in a vertical position and has a water inlet and a water outlet at the top and bottom of the cooling pipe, respectively. The width of the water outlet is consistent with the width of the steel cylinder.

[0009] A water inlet pipe is provided on the frame, one end of the water inlet pipe is connected to the water inlet of the cooling pipe, and the other end of the water inlet pipe is connected to the water source;

[0010] The guide plate is arranged on the cooling pipe and located at the water outlet. The guide plate is in an inclined state. The distance between the top end of the guide plate and the center of the cooling pipe is smaller than the distance between the bottom end and the center of the cooling pipe. A water flow space for water to flow through is left between the bottom end of the guide plate and the inner wall of the cooling pipe.

[0011] By adopting the above technical solution, water is introduced into the cooling pipe through the water inlet pipe. The water flows onto the guide plate and spreads out before entering the water flow space. Then, the water flows evenly from the water outlet along the inner wall of the cooling pipe to the steel cylinder. Then, the two supporting rollers are rotated to drive the steel cylinder to rotate, so that the water flows evenly on the surface of the steel cylinder, reducing the probability of uneven cooling on the surface of the steel cylinder and ensuring the quenching quality of the steel cylinder.

[0012] Optionally, two of the four inner side walls of the cooling tube are opposite to each other and are installation side walls, and the other two inner side walls of the cooling tube are water flow side walls. The guide plate is arranged on the two installation side walls, and the two installation side walls are both in a vertical state, and the two water flow side walls are both in an inclined state, and the distance between the top ends of the two water flow side walls is greater than the distance between the bottom ends.

[0013] By adopting the above technical solution, the two mounting side walls are set to a vertical state, thereby facilitating the installation of the guide plate, and the two water flow side walls are set to an inclined state, so that after the guide plate guides the water flow to the water flow side wall, the flow time of the water flow on the water flow side wall becomes longer, thereby improving the uniformity of the water flow dispersion and ensuring the uniformity of the water flow to the cylinder.

[0014] Optionally, flow stabilizers are provided on the two mounting side walls, and the flow stabilizers are located below the guide plate. The flow stabilizers are parallel to the water flow side walls, and a flow stabilizing space connected to the water flow space is formed between the flow stabilizers and the water flow side walls. The water flows out of the water flow space and enters the flow stabilizing space.

[0015] By adopting the above technical solution, a flow stabilizing plate parallel to the water flow side wall is set on the installation side wall, so that after the water flows from the water flow space to the water flow side wall, the flow stabilizing plate enables the water flow to flow stably in the flow stabilizing space, reducing the probability of water flow splashing on the water flow side wall and causing water flow instability, thereby improving the uniformity and stability of the water flow.

[0016] Optionally, two guide plates and two flow stabilizers are provided, and the two guide plates are respectively located on both sides of the center of the cooling pipe close to the two water flow side walls, and the two flow stabilizers are respectively located on both sides of the center of the cooling pipe close to the two water flow side walls. Overflow grooves are provided on the two mounting side walls, and the overflow grooves are located between the two guide plates. The top ends of the two guide plates are in conflict with the outer walls of the overflow grooves, and the outlet end of the water inlet pipe extends into the overflow groove.

[0017] By adopting the above technical solution, an overflow trough is fixed between the two guide plates, and the water from the water inlet pipe flows into the overflow trough. After the water overflows the overflow trough, it flows onto the two guide plates. The overflow trough allows impurities in the water discharged from the water inlet pipe to settle at the bottom of the overflow trough, thereby reducing the impurity content in the water flowing onto the guide plates, reducing the probability that impurities in the water react with the surface of the steel cylinder when the water flow cools the steel cylinder and has an adverse effect on the steel cylinder, thereby ensuring the quality of the finished product of the steel cylinder.

[0018] Optionally, the center of the guide plate is rotatably mounted on two mounting side walls, and the cooling pipe is provided with a first adjustment component for adjusting the size of the water flow space, the first adjustment component comprising:

[0019] A rotating shaft, the rotating shaft is rotatably disposed on the cooling tube and fixedly connected to the guide plate;

[0020] a first rotating wheel, the first rotating wheel being arranged on a rotating shaft;

[0021] a second rotor, the second rotor being rotatably mounted on the cooling tube, the second rotor having a diameter larger than the first rotor;

[0022] A transmission belt, the transmission belt being sleeved on the first rotating wheel and the second rotating wheel;

[0023] A first regulating motor is provided on the cooling tube and an output shaft of the first regulating motor is connected to the second rotating wheel.

[0024] By adopting the above technical solution, the first adjusting motor starts and drives the second wheel to rotate, the rotation of the second wheel drives the transmission belt to rotate, the rotation of the transmission belt drives the first wheel to rotate, the rotation of the first wheel drives the rotation of the shaft, the rotation of the shaft drives the rotation of the guide plate, and the rotation of the guide plate adjusts the size of the water flow space, thereby completing the adjustment of the water output of the guide plate by controlling the first adjusting motor, thereby improving the adaptability of the cooling device to cooling cylinders of different sizes.

[0025] Optionally, the overflow trough includes a bottom plate and two rotating plates, the bottom plate is arranged on two mounting side walls and is in a horizontal state, the two rotating plates are rotatably arranged on the bottom plate and are respectively located on both sides of the bottom plate close to the two guide plates, the rotating plates are in contact with the top side walls of the guide plates and rotate as the guide plates rotate.

[0026] By adopting the above technical solution, the rotating plate rotates with the guide plate as the guide plate rotates. The rotation of the rotating plate lowers the overflow plane of the overflow trough, thereby increasing the amount of water overflowing from the overflow trough, thereby achieving the goal of increasing the water output while increasing the water flow space.

[0027] Optionally, the flow stabilizer is slidably installed on the two mounting side walls in a direction close to or away from the water flow side wall, the top end of the flow stabilizer is rotatably connected to the bottom end of the guide plate, the flow stabilizer moves as the guide plate rotates, and the cooling pipe is provided with a stabilizing component for keeping the flow stabilizer parallel to the water flow side wall at all times.

[0028] By adopting the above technical solution, the flow stabilizing plate moves as the guide plate rotates under the action of the stabilizing component, thereby achieving synchronous adjustment of the flow stabilizing space and the water flow space, thereby improving work efficiency.

[0029] Optionally, the stabilizing component includes:

[0030] a stabilizing shaft, the stabilizing shaft being arranged on the mounting side wall;

[0031] A connecting rod, one end of which is rotatably connected to the stabilizing shaft, the other end of which is rotatably connected to an end of the flow stabilizing plate away from the guide plate, and the axial direction of the connecting rod is parallel to the flow direction of the water on the guide plate.

[0032] By adopting the above technical solution, the rotation of the guide plate drives one end of the flow stabilizer to move, and the movement of the flow stabilizer drives the connecting rod to rotate synchronously with the guide plate around the stabilization axis of the cover, thereby achieving the working effect that the flow stabilizer can always remain parallel to the side wall of the water flow while moving with the guide plate.

[0033] Optionally, a stepless frequency conversion speed regulation motor is provided on the frame, the output shaft of the stepless frequency conversion speed regulation motor is connected to the carrying roller, a stepless frequency conversion speed regulation water pump is provided on the water inlet pipe, a controller is provided on the frame, the stepless frequency conversion speed regulation motor and the stepless frequency conversion speed regulation water pump are both electrically connected to the controller, and a flow meter is provided on the water inlet pipe.

[0034] By adopting the above technical solution, when the size of the cylinder changes, the stepless variable speed water pump and the stepless variable speed motor are synchronously adjusted through the control controller, and the flow rate of the water inlet pipe can be accounted for in real time through the flow meter, so that the rotation speed of the cylinder and the water output of the cooling pipe are matched and adapted, thereby improving the cooling effect of cylinders of different sizes.

[0035] Optionally, the cooling pipe is provided with a baffle for blocking the surrounding side of the water inlet of the cooling pipe.

[0036] By adopting the above technical solution, the baffle is fixed on the surrounding side of the water inlet of the cooling pipe, thereby reducing the probability of water in the overflow trough overflowing onto the guide plate and splashing into the working environment, and reducing the probability of various impurities in the environment entering the guide plate.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. Water is introduced into the cooling pipe through the water inlet pipe. The water flows onto the guide plate and spreads out before entering the water flow space. Then, it flows evenly along the inner wall of the cooling pipe from the water outlet to the cylinder. Then, the two bearing rollers are rotated to drive the cylinder to rotate, so that the water flows evenly on the surface of the cylinder, reducing the probability of uneven cooling on the cylinder surface and ensuring the quality of the finished cylinder.

[0039] 2. By setting the two mounting side walls in a vertical state, it is convenient to install the guide plate, and setting the two water flow side walls in an inclined state. After the guide plate guides the water flow to the water flow side walls, the water flow time on the water flow side walls becomes longer, which improves the uniformity of water flow dispersion and ensures the uniformity of water flow to the cylinder;

[0040] 3. When the guide plate rotates and drives one end of the flow stabilizer to move, the movement of the flow stabilizer drives the connecting rod to rotate synchronously with the guide plate around the stabilization axis of the cover, thereby achieving the working effect that the flow stabilizer can always remain parallel to the side wall of the water flow while moving with the guide plate.

Among the four inner side walls of the cooling pipe 21, two opposite inner side walls are installation side walls 24, and the other two opposite inner side walls are water flow side walls 25. The two installation side walls 24 are both in a vertical state, and the two water flow side walls 25 are both in an inclined state.

[0048] Reference Figure 1 and Figure 2 The water inlet pipe 22 is fixedly connected to the frame 1. One end of the water inlet pipe 22 is connected to the water inlet of the cooling pipe 21, and the other end of the water inlet pipe 22 is connected to the water source.

[0049] Reference Figure 1 and Figure 2 Two guide plates 23 are provided. Each of the two guide plates 23 is rotatably connected to the two mounting side walls 24 and is located on either side of the overflow trough 3. The rotation axis of the guide plates 23 is located at their center. The top ends of the two guide plates 23 abut against the outer sides of the two rotating plates 32. A water flow space is formed between the bottom ends of the two guide plates 23 and the two water flow side walls 25 for the water to flow through.

The first adjustment component 4 includes a rotating shaft 41, a first rotating wheel 42, a second rotating wheel 43, a transmission belt 44 and a first adjustment motor 45. The rotating shaft 41 is rotatably connected to the two mounting side walls 24 and horizontally passes through the center of the guide plate 23 and is fixedly connected to the guide plate 23. The first rotating wheel 42 is fixedly connected to the rotating shaft 41 and is located at the end of the rotating shaft 41 extending outside the cooling pipe 21. The second rotating wheel 43 is rotatably connected to the outer wall of the cooling pipe 21 on one side of the first rotating wheel 42.

The first adjusting motor 45 is fixedly connected to the outer wall of the cooling pipe 21 and its output shaft is connected to the second rotating wheel 43.

[0051] Reference Figure 1 and Figure 2 The first adjustment motor 45 is activated to rotate the second rotating wheel 43. The rotation of the second rotating wheel 43 drives the transmission belt 44, which in turn drives the first rotating wheel 42. The rotation of the first rotating wheel 42 drives the rotation of the rotating shaft 41. The rotation of the rotating shaft 41 drives the rotation of the guide plate 23. The rotation of the guide plate 23 adjusts the size of the water flow space. Simultaneously with the rotation of the guide plate 23, the rotating plate 32 of the overflow trough 3 rotates with the rotation of the guide plate 23. As the size of the water flow space is adjusted, the overflow plane of the overflow trough 3 is also adjusted accordingly.

[0052] Reference Figure 1 and Figure 2 Two flow stabilizers 26 are installed on the two mounting side walls 24, each located below the two guide plates 23. Each flow stabilizer 26 is parallel to a water flow side wall 25 located near the stabilizer 26. The top of the flow stabilizer 26 is pivotally connected to the bottom of the guide plate 23 and moves with the rotation of the guide plate 23. Stabilizing components 5 are installed on the two mounting side walls 24. The stabilizer assemblies 5 ensure that the bottom of the flow stabilizer 26 remains parallel to the water flow side wall 25 while moving with the guide plate 23.

[0053] Reference Figure 2 The stabilizing assembly 5 includes a stabilizing shaft 51 and a connecting rod 52. The stabilizing shaft 51 is fixedly connected to the two mounting side walls 24. One end of the connecting rod 52 is rotatably connected to the stabilizing shaft 51, and the other end of the connecting rod 52 is rotatably connected to the bottom end of the flow stabilizer 26. The connecting rod 52 is parallel to the deflector 23.

[0054] Reference Figure 2 The guide plate 23 rotates to drive the flow stabilizing plate 26 to move, and the movement of the flow stabilizing plate 26 drives the connecting rod 52 to rotate around the stabilizing axis 51, so that the flow stabilizing plate 26 always remains parallel to the water side wall 25 while moving.

[0055] Reference Figure 1 and Figure 2The frame 1 is fixedly connected to a controller 14, which is electrically connected to the stepless variable frequency speed regulating motor 12 and the stepless variable frequency speed regulating water pump 13. A baffle 15 is fixedly connected to the upper surface of the cooling pipe 21 to block the surrounding side of the water inlet of the cooling pipe 21.

[0056] The working principle of the embodiment of this application is as follows:

[0057] Water is introduced into the overflow trough 3 through the water inlet pipe 22. After overflowing from the overflow trough 3, the water flows onto the guide plate 23 and spreads out. Then the water flows through the water flow space along the water flow side wall 25 and flows evenly from the water outlet to the cylinder. At the same time, the stepless frequency conversion speed regulation motor 12 is started to drive the two supporting rollers 11 to rotate. The rotation of the two supporting rollers 11 drives the cylinder to rotate, so that the water flows evenly on the surface of the cylinder, reducing the probability of uneven cooling of the cylinder surface and ensuring the quality of the finished product of the cylinder.
