Description

Technical Field

[0001] This application relates to the technical field of roll production, and in particular to a cooling device for roll quenching. Background Technology

[0002] Rolls are the main working parts and tools on a rolling mill that cause continuous plastic deformation of metal. A roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in the rolling of the metal.

[0003] Roll quenching is a key heat treatment process in roll manufacturing. It improves the hardness, strength and wear resistance of the roll surface by heating and rapid cooling to meet the requirements of high pressure, friction and impact during the rolling process.

[0004] When quenching some large rolls, the cooling pool structure is relatively simple and the rolls are also large. Generally, the chain is wound around the roll manually and then lifted into the cooling pool by a crane for cooling. When winding the chain, it needs to be done manually, and the workers will face a harsh high-temperature environment, which is dangerous. The hoisting and transportation also pose significant safety hazards.

[0005] Therefore, it is urgent to improve the existing cooling equipment in order to enhance safety and production efficiency. Utility Model Content

[0006] The purpose of this application is to provide a cooling device for quenching rolls to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides a cooling device for roll quenching, which adopts the following technical solution: A cooling device for quenching rolls includes a cooling pool. A lifting and receiving mechanism is provided in the cooling pool. The lifting and receiving mechanism includes a scissor lift, a receiving platform, and a rotary drive mechanism. The scissor lift is installed in the cooling pool, the rotary drive mechanism is installed on the scissor lift, and the receiving platform is installed on the rotary drive mechanism. The rotary drive mechanism can drive the receiving platform to adjust its angle. A plurality of conveying rollers are evenly installed on the surface of the receiving platform. A drive motor is also installed on the side of the receiving platform to drive the conveying rollers.

[0008] The rotary drive mechanism includes a servo rotary platform, which is fixed on the scissor lift. The receiving platform includes a frame, which is fixed on the servo rotary platform, and a plurality of conveying rollers are installed on the frame.

[0009] A transmission belt connects adjacent conveyor rollers, and a drive wheel is fixed to the output end of the drive motor.

[0010] Preferably, to prevent the rollers from accidentally rolling off, an L-shaped retaining wall is also fixed on the frame.

[0011] Preferably, in order to achieve automatic loading and unloading and form a production line, heavy-duty roller conveyors are also provided on both sides of the receiving platform in the cooling pool.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the cooling device for roll quenching is equipped with a lifting and receiving mechanism and is used in conjunction with a heavy-duty roller conveyor to achieve automatic feeding and unloading. The entire cooling process does not require the participation of personnel, which not only enables automated production and processing but also reduces safety hazards. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0017] This application discloses a cooling device for quenching rolls, referring to... Figure 1-2 The cooling pool 1 includes a lifting and receiving mechanism, which includes a scissor lift 2, a receiving platform 3, and a rotary drive mechanism. The scissor lift 2 is installed in the cooling pool 1, the rotary drive mechanism is installed on the scissor lift 2, and the receiving platform 3 is installed on the rotary drive mechanism. The rotary drive mechanism can drive the receiving platform 3 to adjust its angle. Several conveying rollers 32 are evenly installed on the surface of the receiving platform 3. A drive motor 33 is also installed on the side of the receiving platform 3. The drive motor 33 is used to drive the conveying rollers 32 to work. Heavy-duty roller conveyors 5 are also installed on both sides of the receiving platform 3 in the cooling pool 1. One heavy-duty roller conveyor 5 is used to connect with the discharge track of the heating furnace, and the other heavy-duty roller conveyor 5 is used for the discharge of the rolled material after cooling, so as to realize mechanized production.

[0018] Reference Figure 1-2The rotary drive mechanism includes a servo rotary platform 4, which is fixed on the scissor lift 2. The receiving platform 3 includes a frame 31, which is fixed on the servo rotary platform 4. Several conveying rollers 32 are installed on the frame 31. A transmission belt is connected between adjacent conveying rollers 32. A drive wheel is fixed at the output end of the drive motor 33. A transmission belt is also connected between the drive wheel and the conveying rollers 32.

[0019] Reference Figure 2 To prevent the rollers from accidentally rolling off, an L-shaped retaining wall 6 is also fixed on the frame 31.

[0020] The implementation principle of a cooling device for quenching rolls in this application is as follows: After heating, the roll moves along with the base to a heavy-duty roller conveyor 5 on one side, and is then conveyed by the heavy-duty roller conveyor 5 to the receiving platform 3. Subsequently, the scissor lift 2 drives the receiving platform 3 downward, immersing the roll in water for rapid cooling, which improves the hardness, strength, and wear resistance of the roll surface. After cooling, the scissor lift 2 drives the receiving platform 3 to its original position, and the servo rotating platform 4 drives the receiving platform 3 to rotate and connect it to the heavy-duty roller conveyor 5 on the other side. The drive motor 33 drives the conveyor roller 32 to rotate, conveying the roll and the base together to the heavy-duty roller conveyor 5 for discharge. The entire process requires no manual intervention, which not only realizes automated production processing but also reduces safety hazards.

[0021] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
