Description

Technical Field

[0001] This invention belongs to the field of heat treatment technology, specifically a heat treatment device for processing conveyor machinery parts. Background Technology

[0002] Conveying machinery plays a crucial role in numerous fields such as industrial production and logistics transportation. The performance of its components directly affects the overall operational stability, efficiency, and service life of the conveying machinery. Heat treatment, as an important step in the processing of conveying machinery components, can significantly improve the internal structure of the components and enhance their mechanical properties, such as hardness, strength, and toughness, thereby meeting the usage requirements under different working conditions.

[0003] The existing publication number CN111910056B discloses a heat treatment device for processing conveyor machinery parts. This heat treatment device includes a supporting base plate, with a first mounting plate and a second mounting plate on the top of the supporting base plate. A first sliding groove is formed on the first mounting plate, and a sliding rod is fixedly installed within the first sliding groove. This heat treatment device can automatically clamp and fix the pipe, eliminating the need for manual heating of the pipe by hand. This avoids the possibility of burns to workers during operation, effectively reducing the labor intensity of workers, enhancing the safety of the device, and improving its practicality. It also eliminates the need for manual immersion of the heated pipe in water for cooling, avoiding the risk of burns from splashing water vapor due to large temperature differences. This further reduces the labor intensity of workers and enhances the safety of the device.

[0004] However, in the aforementioned devices, the workpiece is stationary or only undergoes simple movement in one direction during heat treatment. This method can easily lead to inconsistent heating and cooling rates in different parts of the workpiece, resulting in localized heating or uneven cooling. During heating, the parts of the workpiece closer to the heat source heat up too quickly, while the parts farther away heat up slowly, causing a large internal temperature gradient and thus inducing thermal stress. Similarly, during cooling, the difference in cooling rate will cause different shrinkage rates in different parts of the workpiece, generating internal stress. If these thermal and internal stresses exceed the material's tolerance limits, they will lead to quality problems such as workpiece deformation and cracking, seriously affecting the performance and reliability of the workpiece after heat treatment, reducing the product qualification rate, and increasing production costs.

[0005] Therefore, it is necessary to provide a new heat treatment device for processing conveyor machinery parts to solve the above-mentioned technical problems. Summary of the Invention

[0061] In some embodiments, reference is made to Figure 4As shown, the frame 100 includes a base 101, multiple support rods 102, multiple connecting seats 103, and a top ring 104.

[0067] The above scheme is adopted: multiple radiant heating tubes 202 are arranged in a ring on the inner wall of the heat-insulating core 205 to ensure uniform heating.

[0068] In some embodiments, reference is made to Figure 7 As shown, the quenching and cooling assembly 300 includes a cooling chamber 301, a filter plate 302, and a spraying mechanism. A maintenance port for replacing the filter plate 302 is provided on one side of the cooling chamber 301. The filter plate 302 is slidably installed on the inner wall of the cooling chamber 301. The spraying mechanism is fixed to the outer side of the cooling chamber 301, and the end of the spraying mechanism extends above the filter plate 302.

[0069] Specifically, the quenching and cooling assembly 300 also includes two first support frames 303, two second support frames 304, two guide rails 305, a sliding top cover 306, a second drive motor 307, and a threaded rod 308. The two first support frames 303 are respectively fixed to one side of the top of the cooling chamber 301, and the two second support frames 304 are respectively fixed to the other side of the top of the cooling chamber 301.

[0071] For details, please refer to Figure 8 As shown, the spraying mechanism includes a cooling water tank 310, a return pipe 311, a filter circulation pump 312, a water extraction pipe 313, and a water supply pipe 314. The cooling water tank 310 is fixed to the top of the base 101. The two ends of the return pipe 311 are respectively connected to the cooling chamber 301 and the inner cavity of the cooling water tank 310, and one end of the return pipe 311 is located below the filter screen.

[0072] The atomizing nozzle 316 is tilted towards the top of the cooling chamber 301, and a water temperature sensor is installed in the cooling water tank 310 to monitor the cooling water temperature.

[0073] The above solution involves circulating and filtering the cooling water using a filter pump 312, which reduces water waste and achieves the goal of energy conservation and environmental protection. Meanwhile, the demisting fan 309 improves the working environment and reduces the impact on the health of operators. The water temperature sensor can monitor the temperature parameters during the heating and cooling process in real time, allowing operators to adjust the process parameters in a timely manner and ensure that the heat treatment process is always in the best condition, thereby further improving the quality of heat treatment.

[0074] Working principle and usage process of this invention:

[0075] First, the operator clamps and fixes the mechanical parts to be heat-treated using the clamping assembly 500, starts the main drive motor 407, drives the main gear 408 to rotate, and then drives multiple planetary gears 406 to rotate. This causes multiple planetary shafts 403 to drive the station turntables 405 at their bottom and the mechanical parts on the clamping assembly 500 to revolve and rotate. In this device, the number of station turntables 405 is preferably three. Through reasonable control, when the station turntables 405 stop rotating, two of the station turntables 405 can be kept in the same position as the heating assembly 200 and the quenching and cooling assembly 300, respectively. When the workpiece rotates to the position of the heating assembly 200 with the station turntables 405, the extension and retraction of the second electric cylinder 601 drives the main drive motor 407 and the entire planetary rotating assembly 400 to be raised and lowered, so that the multiple planetary gears 406 disengage from the large gear ring 401, ensuring the accurate relative position between the workpiece and the heating assembly 200.

[0076] Secondly, when the mechanical parts enter the heating chamber housing 201, the first drive motor 210 rotates in the forward direction, driving the first movable door plate 203 and the second movable door plate 204 to move in opposite directions, keeping the interior of the heating chamber housing 201 relatively sealed. The radiant heating tube 202 heats the workpiece. At the same time, multiple temperature sensors installed in the heating assembly 200 monitor the temperature at different locations in the heating chamber in real time. During the heating process, the first electric cylinder 409 can push the fixed plate 410 down, so that the fixed plate 410 is embedded in the fixed groove at the top of the guide sleeve 404, positioning the guide sleeve 404. Then, the main drive motor 407 is restarted, driving the mechanical parts on multiple station turntables 405 to rotate on their own axis but not around the revolution. After the heating is completed, the first drive motor 210 rotates in the reverse direction, and the first movable door plate 203 and the second movable door plate 204 move away from each other, closing the heating chamber.

[0077] Then, the extension and retraction of the second electric cylinder 601 drives the main drive motor 407 and the entire planetary rotating assembly 400 to be raised and lowered, so that multiple planetary gears 406 re-mesh with the large gear ring 401. Then, the first electric cylinder 409 drives the fixed plate 410 to rise, so that the fixed plate 410 disengages from the fixed groove at the top of the guide sleeve 404. At this time, the main drive motor 407 is started again to drive the main gear 408 to rotate, which in turn drives multiple planetary gears 406 to rotate, so that multiple planetary shafts 403 drive the workstation turntable 405 at its bottom and the mechanical parts on the clamping assembly 500 to revolve and rotate, and move the heated mechanical parts to the top of the quenching and cooling assembly 300.

[0078] Then, the main drive motor 407 and the entire planetary rotating assembly 400 are repeatedly raised and lowered by the extension and retraction of the second electric cylinder 601, so that multiple planetary gears 406 are disengaged from the large gear ring 401, ensuring that the relative position between the workpiece and the quenching and cooling assembly 300 is accurate.

[0079] The second drive motor 307 rotates in the forward direction, driving the threaded rod 308 to rotate, causing the sliding top cover 306 to slide along the two guide rails 305, opening the cooling chamber 301. The planetary shaft 403 passes through the through slot on the sliding top cover 306 to send the workpiece into the cooling chamber 301. After the cooling chamber 301 is closed, the spraying mechanism starts working. The filter circulation pump 312 starts, drawing cooling water from the cooling water tank 310 through the water extraction pipe 313 and delivering it to the interior of the cooling chamber 301 through the water replenishment pipe 314. The atomizing nozzles 316 evenly spray the cooling water onto the workpiece, achieving quenching cooling. The cooling water is used... The water then flows back to the cooling water tank 310 through the return pipe 311. The filter plate 302 is horizontally slidably installed on the inner wall of the cooling chamber 301, which can filter the returned water and remove impurities. During the cooling process, the de-fogging fan 309 fixed on the sliding top cover 306 works to discharge the mist generated in the cooling chamber 301 and improve the working environment. After the cooling is completed, the second drive motor 307 rotates in the forward direction, driving the threaded rod 308 to rotate, so that the sliding top cover 306 slides along the two guide rails 305 to open the cooling chamber 301. Repeated movement moves the mechanical parts to a position away from the cooling chamber 301.

[0080] Finally, when the mechanical parts are moved to the loading and unloading station, the clamping assembly 500 is released to unload the mechanical parts;
