[0002] In fields such as machinery manufacturing, petrochemicals, and pipeline engineering, flange forgings are key components connecting pipelines and equipment, and their mechanical properties directly affect the safe operation and service life of the entire system. To ensure that flange forgings meet preset mechanical performance indicators, heat treatment is an indispensable core process in production. Among these processes, graded temperature control treatment, which can precisely regulate temperature in multiple stages to optimize the internal grain structure of the forgings and eliminate internal stress, has become an important technological means to improve the quality of flange forgings. This utility model is a graded temperature control heat treatment device for flange forgings.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 5 Example 1: This utility model proposes a graded temperature-controlled heat treatment device for flange forgings, comprising: a base plate 1; a mounting seat 2 is mounted on the base plate 1, a rotatable transmission box 21 is mounted on the mounting seat 2, and a worm gear transmission seat 22 is mounted on the mounting seat 2. The output end of the worm gear transmission seat 22 is connected to the rotating shaft of the transmission box 21, and a handwheel 221 is mounted on the input end of the worm gear transmission seat 22. A first motor 211 is mounted on the transmission box 21, and a turntable 23 is mounted on the output shaft of the transmission box 21. A clamping plate 24 for holding flange forgings is mounted on the turntable 23. A first bracket 3 and a second bracket 4 are mounted on the base plate 1, and a first heating nozzle 34 and a second heating nozzle 462 are respectively provided on the first bracket 3 and the second bracket 4. Four feet 11 are locked onto the base plate 1 by nuts.

[0024] In this embodiment of the utility model, a first plate 31 is bolted to a first bracket 3, and a first movable block 33 that can move up and down is mounted on the first plate 31. A first heating nozzle 34 is bolted to the first movable block 33. A second motor 311 is bolted to the first plate 31, and a first base block 32 is bolted to the first bracket 3. Pulleys are mounted on the output shafts of both the first base block 32 and the second motor 311. A first transmission belt 321 connects the two pulleys and is fixedly connected to the first movable block 33. A first position sensor is mounted on the first plate 31. Sensor 332, the first movable block 33 is equipped with a first sensing plate 331 that works in conjunction with the first position sensor 332. Its function is to control the second motor 311 to start, and drive the first movable block 33 to move up and down through the pulley and the first transmission belt 321, so as to realize the position adjustment of the first heating nozzle 34, adapt to different forgings and ensure heating stability. The first position sensor 332 and the first sensing plate 331 work together to monitor, and when the first movable block 33 moves to the limit position, it triggers the second motor 311 to stop, so as to realize anti-collision protection and precise positioning of the first heating nozzle 34, and ensure the quality of the forging.

[0025] In Example 2, based on Example 1, a sliding plate 41 that can slide back and forth is installed on the second bracket 4. A third motor 412 and a second base block 411 are installed on the sliding plate 41. Pulleys are installed on both the output shaft of the third motor 412 and the second base block 411. A second transmission belt 413 connects the two pulleys. A hydraulic rod 44 is installed on the second bracket 4. A connecting plate 441 is fixedly installed on the piston rod of the hydraulic rod 44. A connecting rod 442 is fixedly installed between the connecting plate 441 and the sliding plate 41. A lifting plate 45 that can move up and down is installed on the sliding plate 41. The lifting plate 45 is fixedly connected to the second transmission belt 413. A second position sensor 47 is installed on the sliding plate 41. A second position sensor 45 that works in conjunction with the second position sensor 47 is installed on the lifting plate 45. The sensor plate 451 and the lifting plate 45 are equipped with a connecting seat 46. The connecting seat 46 is bolted to the mounting bracket 461. The second heating nozzle 462 is mounted on the mounting bracket 461. Its function is to control the extension and retraction of the hydraulic rod 44, and drive the sliding plate 41 to slide back and forth through the connecting plate 441 and the connecting rod 442, so as to realize the back and forth position adjustment of the second heating nozzle 462 to meet the back and forth heating requirements of the forging. It also controls the operation of the third motor 412, which drives the lifting plate 45 to move up and down through the pulley and the second transmission belt 413, so as to realize the up and down position adjustment of the second heating nozzle 462 to meet the up and down heating requirements of the forging. The second position sensor 47 works with the second sensor plate 451 to monitor the position of the lifting plate 45, prevent it from moving excessively, and ensure the accurate position of the second heating nozzle 462.

[0026] In Example 3, based on Examples 1 and 2, the second heating nozzle 462 has a square structure, and the first heating nozzle 34 has a cylindrical structure. A first support 42 and a second support 43 are respectively installed on the second bracket 4. Both the first support 42 and the second support 43 are equipped with distance sensors 421 for monitoring the front-to-back distance of the sliding plate 41. Their function is as follows: the second heating nozzle 462 is square, and the first heating nozzle 34 is cylindrical. By adapting to the heating requirements of different areas of the flange forging through different shapes, a multi-dimensional uniform temperature control effect is achieved. The distance sensors 421 on the first support 42 and the second support 43 monitor the front-to-back distance of the sliding plate 41 in real time, achieving precise control of the sliding plate 41's movement position and preventing the sliding plate 41 from shifting and affecting heating. Combined with the monitoring data from the distance sensors 421 and the movement control of the sliding plate 41 and the lifting plate 45, the second heating nozzle 462 is precisely aligned with the forging, further improving the accuracy of graded temperature control.

[0027] The working principle of this embodiment is as follows: First, the flange forging is fixed on the turntable 23 by the clamp 24. Then, the first motor 211 on the transmission box 21 is started. The first motor 211 drives the turntable 23 to rotate, thereby driving the flange forging to rotate synchronously, so that the subsequent heating is more uniform. If it is necessary to adjust the angle of the forging, the handwheel 221 can be turned to drive the transmission box 21 to rotate through the worm gear transmission seat 22, so that the forging is in a suitable processing posture. Then, the second motor 311 on the first bracket 3 is started. It drives the first movable block 33 to move up and down through the pulley and the first transmission belt 321, thereby adjusting the height of the cylindrical first heating nozzle 34. At the same time, the first position sensor 332 on the first plate 31 cooperates with the first sensing plate 331 on the first movable block 33 to ensure that the first heating nozzle 34 stops at the preset position to accurately heat the forging. In the corresponding area, on the second support 4, the hydraulic rod 44 drives the sliding plate 41 to slide back and forth through the connecting plate 441 and the connecting rod 442. The distance sensor 421 on the first support 42 and the second support 43 monitors the front and rear distance of the sliding plate 41 in real time to avoid exceeding the safe range. At the same time, the third motor 412 on the sliding plate 41 drives the lifting plate 45 to move up and down through the pulley and the second transmission belt 413 to adjust the height of the square structure of the second heating nozzle 462. The second position sensor 47 on the sliding plate 41 and the second sensing plate 451 on the lifting plate 45 cooperate to achieve precise positioning. Finally, the first motor 211 drives the forging to rotate, the first heating nozzle 34 and the second heating nozzle 462 perform graded heating, multi-dimensional position adjustment and real-time monitoring of each sensor to complete the graded temperature control heat treatment operation of the flange forging.
