Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically to a rotating bushing isothermal quenching cooling device. Background Technology

[0002] In the field of metal processing, rotating bushings are key components, and their performance plays a decisive role in equipment operation. Isothermal quenching, as a heat treatment process that can significantly improve the overall performance of rotating bushings, has attracted much attention. Currently, traditional isothermal quenching cooling devices for rotating bushings have many shortcomings. On the one hand, during the quenching process, the uneven temperature distribution of the cooling medium leads to different cooling rates in different parts of the bushing, ultimately resulting in differences in the internal structure and properties of the bushing, failing to meet the requirements of high precision and high reliability. For example, under some complex working conditions, the bushing is prone to localized wear and deformation. On the other hand, existing cooling devices have low levels of automation and cumbersome operating procedures, seriously affecting production efficiency and increasing production costs. Moreover, existing devices also have shortcomings in terms of energy utilization and environmental protection, making it difficult to align with the current trend of green manufacturing. Therefore, the development of an isothermal quenching cooling device for rotating bushings that can achieve uniform cooling, has a high level of automation, is highly efficient, energy-saving, and environmentally friendly is urgently needed.

Additionally, a mandrel is provided; during cooling, the mandrel is pushed into the drill rod welding area to cool the interior, accelerating the cooling speed and ensuring the drill rod's performance. The heating rod is placed in the quenching liquid tank. This invention employs a constant-temperature quenching liquid design and includes an anti-splash cover in the drill rod welding area, solving the problems of pollution and energy waste caused by quenching liquid splashing, while also improving product quality. However, it has shortcomings. When using the device, it is not yet able to adjust its position for different parts during quenching, resulting in lag and low efficiency during the quenching process.

[0027] By installing a rotary braking component 3 on the device, the rotary spraying component can be rotated to perform a cooling operation when using the device. This allows the device to be placed at the center of each material that needs to be quenched, so that a circumferential cooling operation can be performed by rotating the component.

[0028] The lifting support assembly 1 includes a mounting base plate 101. Positioning screws 102 are fixedly installed on the top of both sides of the mounting base plate 101. A lifting support plate 104 is slidably installed in the middle of the positioning screws 102 through a sliding sleeve 103. A fixed limiting plate 105 is fixedly installed on the top of the positioning screws 102. The lifting support assembly 1 provides a supporting foundation for the entire device. The mounting base plate 101 serves as the bottom load-bearing structure. The positioning screws 102 play a guiding and positioning role. The lifting support plate 104 can move up and down along the positioning screws 102 through the sliding sleeve 103. The fixed limiting plate 105 restricts the upward position of the lifting support plate 104. The lifting brake assembly 2 provides power for the lifting of the lifting support plate 104.

[0029] The lifting and braking assembly 2 includes a pneumatic pump 201. A push rod 202 is mounted on the top of the pneumatic pump 201. The top end of the push rod 202 is fixedly installed at the bottom of the middle of the lifting support plate 104 through a connecting block 203. When the pneumatic pump 201 is working, it drives the lifting support plate 104 to slide on the positioning screw 102 through the push rod 202 and the connecting block 203, thereby adjusting the height of the device to meet the quenching requirements of rotating bushings of different specifications.

[0030] The pneumatic pump 201 is fixedly installed at the top center of the mounting base plate 101.

[0031] The rotary motor 301 is fixedly installed on the bottom side of the lifting support plate 104 by a bracket. The active rotating wheel 302 and the passive rotating wheel 304 are limited and set on the top side of the lifting support plate 104. The rotary braking assembly 3 is responsible for driving the rotary spraying assembly 4 to rotate. After the rotary motor 301 is started, it drives the active rotating wheel 302 to rotate. The active rotating wheel 302 transmits power to the passive rotating wheel 304 through the transmission belt 303. The passive rotating wheel 304 then drives the limiting rotating disk 305 to rotate. The limiting base 306 provides limiting support for the limiting rotating disk 305 to ensure the stability of the rotation process.

[0032] The rotary spraying assembly 4 includes a liquid collection tank 401, which is fixedly installed on the top of the limiting rotating disk 305. A water pump 402 is fixedly installed on the top of the liquid collection tank 401. A connecting pipe 403 is fixedly installed on the top of the water pump 402. A shower head 404 is fixedly installed at the other end of the connecting pipe 403. The rotary spraying assembly 4 is used to spray cooling solution onto the rotating bushing. The liquid collection tank 401 stores the quenching cooling medium. The water pump 402 delivers the cooling medium in the liquid collection tank 401 to the shower head 404 through the connecting pipe 403. The shower head 404 rotates under the drive of the limiting rotating disk 305 to achieve uniform spray cooling of the rotating bushing and ensure the consistency of the quenching effect.

[0033] This isothermal quenching and cooling device for rotating bushings achieves precise isothermal quenching and cooling of rotating bushings through the coordinated operation of its components. The lifting support assembly 1 provides the foundation for the entire device. The mounting base plate 101 serves as the bottom load-bearing structure, the positioning screw 102 acts as a guide and positioner, and the lifting support plate 104 can move up and down along the positioning screw 102 via the sliding sleeve 103. The fixed limiting plate 105 restricts the upward position of the lifting support plate 104. The lifting brake assembly 2 provides power for the lifting of the lifting support plate 104. When the pneumatic pump 201 is working, it drives the lifting support plate 104 to slide on the positioning screw 102 via the push rod 202 and the connecting block 203, thereby adjusting the height of the device to accommodate the quenching of rotating bushings of different specifications. The rotary braking assembly 3 drives the rotary spraying assembly 4 to rotate. After the rotary motor 301 starts, it drives the active rotating wheel 302 to rotate. The active rotating wheel 302 transmits power to the passive rotating wheel 304 through the transmission belt 303. The passive rotating wheel 304 then drives the limiting rotating disk 305 to rotate. The limiting base 306 provides limiting support for the limiting rotating disk 305 to ensure the stability of the rotation process. The rotary spraying assembly 4 is used to cool the rotating bushing. The liquid collection tank 401 stores the quenching cooling medium. The water pump 402 transports the cooling medium in the liquid collection tank 401 to the flower through the connecting pipe 403. The spray nozzle 404 rotates under the drive of the limiting rotating disk 305, achieving uniform spray cooling of the rotating bushing and ensuring consistent quenching effect. In the workflow, the rotating bushing to be processed is placed in a suitable position, ensuring all components of the device are in their initial state, the lifting support plate 104 is at its initial height, and the rotating spray assembly 4 is in its initial position. The pneumatic pump 201 in the lifting brake assembly 2 is activated. The pneumatic pump 201 pushes the lifting support plate 104 upwards or downwards along the positioning screw 102 via the push rod 202 and connecting block 203 until the lifting support plate 104 reaches a suitable position for processing the rotating bushing. The height is adjusted, and then the pneumatic pump 201 is turned off. The lifting support plate 104 is fixed on the positioning screw 102 through the sliding sleeve 103. The rotating spray assembly 4 is checked to ensure that the liquid collection tank 401 contains sufficient quenching cooling medium. The water pump 402, connecting pipe 403 and shower head 404 are connected normally. The rotating motor 301 in the rotating brake assembly 3 is started. The rotating motor 301 drives the active rotating wheel 302 to rotate. The active rotating wheel 302 drives the passive rotating wheel 304 to rotate through the transmission belt 303. The passive rotating wheel 304 drives the limit rotating disk 305 and the rotating spray assembly 4 installed on it to rotate together.Simultaneously, the water pump 402 is started, and the water pump 402 transports the cooling medium in the collection tank 401 to the shower head 404 through the connecting pipe 403. The shower head 404 sprays cooling medium evenly onto the rotating bushing during rotation. When the rotating bushing reaches the quenching cooling requirement, the water pump 402 is turned off to stop the spraying of the cooling medium. Then, the rotating motor 301 is turned off, and the rotating spray assembly 4 stops rotating. The pneumatic pump 201 is started to return the lifting support plate 104 to its initial height. Then, the pneumatic pump 201 is turned off, and the processed rotating bushing is removed, completing the entire workflow.
