Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment, and specifically relates to a heat treatment device for forging quenching processing. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, and the microstructure can be optimized. After forging, the forgings need to be further strengthened. For this purpose, the forged forgings need to be heat-treated, and at this time, heat treatment equipment is required. Quenching is a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and held for a period of time, and then immediately immersed in a quenching medium for rapid cooling. Its purpose is to improve the mechanical properties such as strength, hardness, and wear resistance of metal materials to meet the requirements of different engineering applications for material properties. When processing forgings, quenching treatment needs to be performed on the forgings. Therefore, quenching equipment is required. When quenching forgings, spray quenching treatment is mostly used to achieve rapid and uniform cooling.

[0003] Currently, the traditional spray quenching equipment sprays the forgings unevenly. Especially for some large forgings with central holes inside, it is inconvenient to cool the holes, and local overheating and overcooling are likely to occur, thus affecting the overall quenching quality. Summary of the Invention

The outlet penetrates the surface of the quenching pool and extends to the inside thereof, and the coolant can be sucked out from the inside of the quenching pool through the water inlet of the pump body, and under the action of the fluid pressure, the coolant enters the inside of the circular water channel, and then through the transportation of the water pipe, the coolant can be sprayed from the first nozzle to the surface of the forging material at the center of the inner part of the cylindrical cover. When the coolant is sprayed to the surface of the forging material, the heat of the forging material can be absorbed, and the coolant can flow downward to dissipate the heat in time, thereby cooling the surface of the forging material, and the water pipes are evenly installed on the outer cylindrical surface of the cylindrical cover, and the liquid is sprayed to the surface of the forging material through the evenly distributed first nozzles, so that the forging material is cooled quickly and evenly; The auxiliary component includes a round tube and a transmission. The round tube is rotatably installed at the center of the inside of the cylindrical cover. The transmission is installed on the surface of the cylindrical cover and close to the circular water channel. A servo motor is installed on the surface of the transmission. The output end of the servo motor is installed with the round tube through the transmission. A second nozzle is connected to the middle of the outer cylindrical surface of the round tube. Elastic sheets are fixedly installed on both sides of the outer cylindrical surface of the round tube. A scraper is fixedly connected to the top of the elastic sheet. A rotating connector is installed at the liquid inlet of the round tube. The rotating connector is connected to the liquid outlet at the top of the pump body. As the lifted forging material moves toward the inside of the cylindrical cover, the end of the round tube away from the speed reducer passes through the center hole of the forging material, and under the elastic support of the elastic sheet, the edge of the scraper fits with the inner wall of the center hole of the forging material. As the forging material continues to move, the oxide layer impurities on the inner wall of the center hole of the forging material can be scraped off, and the oxide layer on the surface of the forging material is impacted and fallen off by the coolant sprayed from the first nozzle, thereby cleaning the oxide layer attached to the surface of the forging material.

[0005] Preferably, there are six water pipes, and the six water pipes are evenly installed on the outer circumferential surface of the cylindrical cover, the first nozzle is evenly installed on the surface of the water pipe, and the liquid outlet of the first nozzle penetrates the outer circumferential surface of the cylindrical cover and extends into the interior thereof.

[0006] Preferably, the position of the water leakage hole corresponds to the position of the rectangular notch, and the water leakage holes are evenly arranged at the bottom of the outer circular surface of the cylindrical cover.

[0007] Preferably, the second nozzle is evenly installed at the middle of the outer circular surface of the circular tube, the scraper is spiral, and the scraper is evenly installed on both sides of the outer circular surface of the circular tube. By the rotation of the output end of the servo motor and driven by the transmission of the transmission, the circular tube is driven to rotate. And with the rotational connection of the rotary connector, the circular tube rotates smoothly and is not prone to the situation of mechanism jamming. And with the rotation of the circular tube, the second nozzle can be driven to rotate together. And with the coolant being conveyed into the circular tube from the liquid outlet at the top of the pump body, the coolant can be sprayed from the second nozzle to the inner wall of the central hole of the forging material, so as to cool the central hole of the forging material, making the cooling fast and uniform, not prone to local overheating and overcooling, and reducing the temperature difference.

[0008] Preferably, the workpiece taking mechanism includes a linear guide rail and a moving trolley. The linear guide rail is installed at the side of the top of the quenching pool. The moving trolley is rollingly installed in the inner cavity of the top of the linear guide rail. A gantry is fixedly installed on the top of the moving trolley. A guide roller is rollingly installed at the middle of the top of the gantry. A winch is fixedly installed at the side of the top of the gantry and close to the guide roller. A steel wire rope is wound inside the winch. One end of the steel wire rope away from the winch penetrates through the top of the gantry and extends to its bottom. An anti-loosening component is installed at the top of the inner side of the gantry and close to the steel wire rope. The bottom end of the steel wire rope is fixedly connected with a hook. By the winch lowering the steel wire rope and under the pulling force of the self-weight of the hook, the steel wire rope can be elongated, the hook moves downward, and the hook is hooked at the central hole of the forging material. And by using the winch to work again and winding up the steel wire rope, the forging material can be lifted. And under the linear guidance of the linear guide rail, using the moving trolley as the power, the gantry is driven to move by the moving trolley, so that the forging material can be lifted, and the steel wire rope moves from the position of the rectangular notch, so that the forging material can be moved into the inner part of the cylindrical cover, which is convenient for subsequent spray quenching of the forging material.

[0009] Preferably, the linear guide rail is horizontally installed. There are two linear guide rails, and the two linear guide rails are symmetrically installed along the central axis at the middle of the quenching pool.

[0010] Preferably, the anti-loosening component includes a connecting frame and an L-shaped swing plate. The top end of the connecting frame is fixedly installed at the side of the surface of the gantry frame near the winch by screws. The side of the surface of the L-shaped swing plate is hinged to the bottom end of the connecting frame. A roller is rotatably installed at the top of the L-shaped swing plate near the steel wire rope. A C-shaped support tooth is fixedly installed at the bottom of the L-shaped swing plate. A connecting roller is rotatably installed on the inner side surface of the C-shaped support tooth. An elastic support strip is fixedly installed between the surface of the L-shaped swing plate and the surface of the connecting frame. The winch winds up the steel wire rope. Under the pulling force of the weight of the forging itself, the steel wire rope is in a tightened state. Under the rolling support of the roller, the L-shaped swing plate receives a reverse acting force, so that the L-shaped swing plate drives the C-shaped support tooth to rotate counterclockwise, and the elastic support strip is compressed. The outer circular surface of the connecting roller contacts the steel wire rope, and two symmetrical connecting rollers form a V shape, so that the two symmetrical steel wire ropes can be squeezed towards the middle, so that the hook receives a reverse pulling force, so that the hook hooks the forging material stably and is not easy to unhook, which is safe and reliable.

[0011] Preferably, the C-shaped support tooth is obliquely installed. There are two connecting rollers, and the two connecting rollers are symmetrically installed along the central axis of the middle of the L-shaped swing plate. The elastic support strip is arc-shaped.

[0012] Preferably, a guiding module is installed on the outer circular surface of the cylindrical cover near the rectangular notch. The guiding module includes a base. The base is fixedly installed at the top of the outer circular surface of the cylindrical cover near the rectangular notch by bolts. A guide post is fixedly connected to the center of the base. A curved surface slider is slidably installed at the end of the outer circular surface of the guide post away from the base. The inner arc surface of the curved surface slider is slidably installed with the inner side of the rectangular notch. A spring is fixedly installed between the surface of the curved surface slider and the surface of the base near the guide post. An open connecting ring is fixedly installed at the bottom of the curved surface slider. An open extension edge is fixedly connected to the edge of the surface of the open connecting ring. The forging material is hooked by the hook and lifted under the pulling force of the steel wire rope. The forging material moves towards the inside of the cylindrical cover. The cross section of the forging material contacts the inner side surface of the open connecting ring. As the forging material continues to move, under the sliding connection of the curved surface slider, the forging material is always at the center inside the cylindrical cover, not easy to be eccentric and not easy to shake, which helps to spray and cool and quench the forging material through the first nozzle and the second nozzle. The spring will be compressed under extrusion. When the hook at the central hole of the forging material contacts the scraping plate, as the forging material continues to move, the scraping plate will receive the pressing force of the hook, and under the elastic support of the elastic piece, the scraping plate will move towards the position close to the round pipe, so that the forging material moves smoothly.

[0013] Preferably, there are two guide posts, and the two guide posts are symmetrically installed along the rectangular notch. The guide posts pass through the center of the spring. The openings at the top of the opening connecting ring and the openings at the top of the opening extension edge correspond to the position of the rectangular notch. After the forging material is quenched, the pump body can be shut down, and the gantry can be driven to move in the reverse direction by the mobile trolley, so that the forging material can be removed from the inside of the cylindrical cover. The driving force received by the opening connecting ring disappears, and under the elastic force of the spring, the curved surface slider drives the opening connecting ring and the opening extension edge to move together to the side away from the inside of the cylindrical cover, so that the opening extension edge moves linearly, and the oxide layer debris falling to the bottom of the inner cavity of the cylindrical cover can be scraped, facilitating the oxide layer debris and the coolant to fall from the water leakage holes, and it is not easy to have the situation of debris accumulation.

[0014] The present invention provides a heat treatment device for forging quenching processing, which has the following beneficial effects: First, in this heat treatment device for forging quenching processing, the coolant is sprayed from the first nozzle onto the surface of the forging material at the center inside the cylindrical cover. As soon as the coolant is sprayed onto the surface of the forging material, the heat of the forging material can be absorbed, and the heat is dissipated in time by the downward flow of the coolant, thereby cooling the surface of the forging material. Moreover, the water pipes are evenly installed on the outer circular surface of the cylindrical cover, and the coolant is sprayed onto the surface of the forging material through the evenly distributed first nozzles, so that the forging material can be cooled quickly and evenly.

[0015] Second, in this heat treatment device for forging quenching processing, as the lifted forging material moves into the cylindrical cover, the end of the round pipe away from the speed reducer passes through the central hole of the forging material. Under the elastic support of the elastic piece, the edge of the scraper fits with the inner wall of the central hole of the forging material. As the forging material continues to move, the oxide layer impurities on the inner wall of the central hole of the forging material can be scraped off, and the oxide layer on the surface of the forging material is washed off by the coolant sprayed from the first nozzle, thereby cleaning the oxide layer attached to the surface of the forging material.

[0016] Third, in this heat treatment device for forging quenching processing, the rotation of the output end of the servo motor is utilized, and under the transmission of the speed reducer, the round pipe is driven to rotate. With the rotational connection of the rotational connector, the round pipe rotates smoothly and is not prone to the situation of mechanism jamming. As the round pipe rotates, the second nozzle can be driven to rotate together. As the coolant is transported from the liquid outlet at the top of the pump body into the round pipe, the coolant can be sprayed from the second nozzle onto the inner wall of the central hole of the forging material, thereby cooling the central hole of the forging material, making the cooling fast and even, not prone to local overheating and overcooling, and reducing the temperature difference.

[0017] IV. The heat treatment equipment for quenching the forging uses a winch to lower the steel wire rope. Under the pulling force of the self-weight of the hook, the steel wire rope can be elongated, causing the hook to move downward. The hook is hooked at the central hole of the forging material. By winding the steel wire rope, the forging material can be lifted. Under the linear guidance of the linear guide rail, using the moving trolley as the power, the gantry can be driven to move by the moving trolley, and the forging can be lifted. The steel wire rope moves from the position of the rectangular notch, and the forging material can be moved into the inner part of the cylindrical cover, facilitating subsequent spray quenching of the forging material.

[0018] V. The heat treatment equipment for quenching the forging, under the pulling force of the self-weight of the forging, makes the steel wire rope in a taut state. Under the rolling support of the roller, the L-shaped swing plate receives a reverse acting force, enabling the L-shaped swing plate to drive the C-shaped support teeth to rotate counterclockwise, and the elastic support strip is compressed. Using the outer cylindrical surface of the connecting roller to contact the steel wire rope, and two symmetric connecting rollers forming a V shape, the two symmetric steel wire ropes can be squeezed towards the middle, causing the hook to receive a reverse pulling force, making the hook hang the forging material stably and not easily prone to unhooking, being safe and reliable.

[0019] VI. The heat treatment equipment for quenching the forging, under the pulling force of the steel wire rope, lifts the forging material and moves it into the inner part of the cylindrical cover. The cross-section of the forging material contacts the inner side surface of the opening connecting ring. As the forging material continues to move and under the sliding connection of the curved surface slider, the forging material is always at the center inside the cylindrical cover, not easily prone to eccentricity and not prone to shaking, which helps to spray and cool and quench the forging material through the first nozzle and the second nozzle.

[0020] VII. The heat treatment equipment for quenching the forging uses the moving trolley to drive the gantry to move in the reverse direction, and the forging material can be moved out of the inner part of the cylindrical cover. The driving force received by the opening connecting ring disappears, and under the elastic force of the spring, the curved surface slider drives the opening connecting ring and the opening extension edge to move together towards the side away from the inner part of the cylindrical cover, causing the opening extension edge to move linearly, and the oxide layer debris falling to the bottom of the inner cavity of the cylindrical cover can be scraped, facilitating the oxide layer debris and the coolant to fall from the water leakage hole and not easily prone to debris accumulation.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The first embodiment is as Figures 1 to 5 shown, and the present invention provides a technical solution: A heat treatment device for forging quenching processing, including a quenching bath 1 and a sewage pipe 2 installed on the surface of the quenching bath 1 near the bottom, and a workpiece picking mechanism 3 is installed on the top of the quenching bath 1; A spraying mechanism 4, which is used for cooling and quenching the forging material, and the spraying mechanism 4 is installed in the middle of the top of the quenching bath 1; Among them, the spraying mechanism 4 includes a cylindrical cover 41 and a pump body 42. The cylindrical cover 41 is fixedly installed in the middle of the top of the quenching pool 1 through a bracket. The pump body 42 is fixedly installed on the surface of the quenching pool 1 and close to the cylindrical cover 41. A water pipe 43 is fixedly installed on the outer circumferential surface of the cylindrical cover 41. A circular water channel 44 is fixedly installed on the surface of the cylindrical cover 41 and close to one side of the pump body 42. The liquid inlet of the circular water channel 44 is communicated with the liquid outlet on the side of the pump body 42. The water pipe 43 is communicated with the circular water channel 44. The liquid outlet of the water pipe 43 is communicated with a first nozzle 45. An auxiliary component 46 is installed at the center of the cylindrical cover 41. Leakage holes 47 are formed at the bottom of the outer circumferential surface of the cylindrical cover 41. A rectangular notch 48 is formed at the top of the outer circumferential surface of the cylindrical cover 41. When the staff starts the pump body 42 to work, and the water inlet of the pump body 42 penetrates through the surface of the quenching pool 1 and extends into its interior, the coolant can be sucked out from the interior of the quenching pool 1 through the water inlet of the pump body 42. Under the action of fluid pressure, the coolant enters the interior of the circular water channel 44. Through the transportation of the water pipe 43, the coolant can be sprayed from the first nozzle 45 onto the surface of the forging material at the center inside the cylindrical cover 41. Whenever the coolant is sprayed onto the surface of the forging material, the heat of the forging material can be absorbed, and the heat can be dissipated in time by the downward flow of the coolant, thereby cooling the surface of the forging material. Moreover, the water pipes 43 are uniformly installed on the outer circumferential surface of the cylindrical cover 41, and the liquid is sprayed onto the surface of the forging material through the uniformly distributed first nozzles 45; There are six water pipes 43, and the six water pipes 43 are uniformly installed on the outer circumferential surface of the cylindrical cover 41. The first nozzles 45 are uniformly installed on the surface of the water pipes 43, and the liquid outlets of the first nozzles 45 penetrate through the outer circumferential surface of the cylindrical cover 41 and extend into its interior.

[0025] The positions of the leakage holes 47 correspond to the positions of the rectangular notch 48, and the leakage holes 47 are uniformly formed at the bottom of the outer circumferential surface of the cylindrical cover 41.

[0026] The auxiliary component 46 includes a circular tube 461 and a transmission 462. The circular tube 461 is rotatably installed at the center inside the cylindrical cover 41. The transmission 462 is installed on the surface of the cylindrical cover 41 and near the circular water channel 44. A servo motor 463 is installed on the surface of the transmission 462. The output end of the servo motor 463 is drivingly installed with the circular tube 461 through the transmission 462. A second nozzle 464 is communicated at the middle of the outer circumferential surface of the circular tube 461. Elastic pieces 465 are fixedly installed on both sides of the outer circumferential surface of the circular tube 461. The top ends of the elastic pieces 465 are fixedly connected with scraping plates 466. A rotating connector 467 is installed at the liquid inlet of the circular tube 461. The rotating connector 467 is communicated with the liquid outlet at the top of the pump body 42. As the lifted forging material moves towards the inside of the cylindrical cover 41, one end of the circular tube 461 away from the transmission 462 passes through the central hole of the forging material. Under the elastic support of the elastic pieces 465, the edge of the scraping plate 466 fits against the inner wall of the central hole of the forging material. As the forging material continues to move, the oxide layer impurities on the inner wall of the central hole of the forging material can be scraped off. The oxide layer on the surface of the forging material is washed off by the coolant sprayed from the first nozzle 45.

[0027] The second nozzles 464 are evenly installed at the middle of the outer circumferential surface of the circular tube 461. The scraping plates 466 are spiral-shaped and are evenly installed on both sides of the outer circumferential surface of the circular tube 461. The staff turns on the servo motor 463 to work. Using the rotation of the output end of the servo motor 463 and driven by the transmission 462, the circular tube 461 is driven to rotate. And with the rotation connection of the rotating connector 467, the circular tube 461 rotates smoothly and is not prone to mechanism jamming. As the circular tube 461 rotates, it can drive the second nozzles 464 to rotate together. And as the liquid outlet at the top of the pump body 42 conveys the coolant into the circular tube 461, the coolant can be sprayed from the second nozzles 464 towards the inner wall of the central hole of the forging material, thereby cooling the central hole of the forging material.

[0028] The second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 7 as shown: The picking mechanism 3 includes a linear guide rail 31 and a moving trolley 32. The linear guide rail 31 is installed on the side of the top of the quenching pool 1. The moving trolley 32 is rollingly installed in the inner cavity of the top of the linear guide rail 31. A gantry 33 is fixedly installed on the top of the moving trolley 32. A guiding roller 34 is rollingly installed at the middle of the top of the gantry 33. A winch 35 is fixedly installed at the side of the top of the gantry 33 and near the guiding roller 34. A steel wire rope 36 is wound inside the winch 35. One end of the steel wire rope 36 away from the winch 35 penetrates through the top of the gantry 33 and extends to its bottom. An anti-loosening component 37 is installed at the top of the inner side of the gantry 33 and near the steel wire rope 36. The bottom end of the steel wire rope 36 is fixedly connected with a hook 38.

Then, the winch 35 is used to work again to wind up the steel wire rope 36, and the forging material can be lifted. Under the linear guidance of the linear guide rail 31, using the moving trolley 32 as the power, the moving trolley 32 drives the gantry 33 to move, and the forging material can be lifted, and the steel wire rope 36 can move from the position of the rectangular notch 48, and the forging material can be moved into the inner part of the cylindrical cover 41, which is convenient for subsequent spray quenching of the forging material.

[0030] The anti-loosening component 37 includes a connecting frame 371 and an L-shaped swinging plate 372. The top end of the connecting frame 371 is fixedly installed at the side of the surface of the gantry 33 near the winch 35 through screws. The side of the surface of the L-shaped swinging plate 372 is hinged to the bottom end of the connecting frame 371. A roller 373 is rotatably installed at the top of the L-shaped swinging plate 372 near the wire rope 36. A C-shaped support tooth 374 is fixedly installed at the bottom of the L-shaped swinging plate 372. A connecting roller 375 is rotatably installed on the inner side surface of the C-shaped support tooth 374. An elastic support strip 376 is fixedly installed between the surface of the L-shaped swinging plate 372 and the surface of the connecting frame 371. The winch 35 winds up the wire rope 36, and under the pulling force of the weight of the forging itself, the wire rope 36 is in a tightened state. Under the rolling support of the roller 373, the L-shaped swinging plate 372 receives a reverse acting force, so that the L-shaped swinging plate 372 drives the C-shaped support tooth 374 to rotate counterclockwise, and the elastic support strip 376 is compressed. The outer circumferential surface of the connecting roller 375 contacts the wire rope 36, and the two symmetrical connecting rollers 375 form a V shape, so that the two symmetrical wire ropes 36 can be squeezed towards the middle, so that the hook 38 receives a reverse pulling force, making the hook 38 hook the forging material stably.

[0031] The C-shaped support tooth 374 is installed obliquely. There are two connecting rollers 375, and the two connecting rollers 375 are symmetrically installed along the central axis in the middle of the L-shaped swinging plate 372. The elastic support strip 376 is arc-shaped.

[0032] Third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 9 as shown: A guiding module 5 is installed on the outer circular surface of the cylindrical cover 41 near the rectangular notch 48. The guiding module 5 includes a base 51 which is fixedly installed at the top of the outer circular surface of the cylindrical cover 41 near the rectangular notch 48 through bolts. A guide post 52 is fixedly connected to the center of the base 51. A curved surface slider 53 is slidably installed on the outer circular surface of the guide post 52 at the end far from the base 51. The inner arc surface of the curved surface slider 53 is slidably installed between the inner sides of the rectangular notch 48. A spring 54 is fixedly installed between the surface of the curved surface slider 53 and the surface of the base 51 near the guide post 52. An open connecting ring 55 is fixedly installed at the bottom of the curved surface slider 53.

The cross-section of the forging material contacts the inner side surface of the open connecting ring 65. As the forging material continues to move and is slidably connected by the curved surface slider 63, the forging material is always located at the center inside the cylindrical cover 41, not easily eccentric and without shaking, which helps to spray and cool the forging material by the first nozzle 45 and the second nozzle 464. The spring 64 will be compressed under extrusion. When the hook 38 at the center hole of the forging material contacts the scraper 466, as the forging material continues to move, the scraper 466 will be pressed by the hook 38 and move towards the position close to the round tube 461 under the elastic support of the elastic piece 465, so that the forging material moves smoothly.

[0033] There are two guide posts 52, and the two guide posts 52 are symmetrically installed along the rectangular notch 48. The guide posts 52 pass through the center of the spring 54. The openings at the top of the open connecting ring 55 and the openings at the top of the open extension edge 56 correspond to the position of the rectangular notch 48. After the quenching of the forging material is completed, the pump body 42 can be turned off, and the mobile trolley 32 is used to drive the gantry 33 to move in the reverse direction, so that the forging material can be removed from the inside of the cylindrical cover 41. The driving force received by the open connecting ring 65 disappears, and under the elastic force of the spring 64, the curved surface slider 63 drives the open connecting ring 65 and the open extension edge 66 to move together towards the side far from the inside of the cylindrical cover 41, so that the open extension edge 66 moves linearly, and the oxide layer debris falling to the bottom of the inner cavity of the cylindrical cover 41 can be scraped, facilitating the oxide layer debris and the coolant to fall from the water leakage hole 47.

[0034] During use, first, the staff injects an appropriate amount of coolant into the quenching pool 1 and starts the mobile trolley 32 to work. The mobile trolley 32 drives the entire gantry 33 to move towards the end far from the cylindrical cover 41. At this time, the staff starts the winch 35 to work. By lowering the steel wire rope 36 with the winch 35 and under the pulling force of the self-weight of the hook 38, the steel wire rope 36 can be elongated, causing the hook 38 to move downward. Then, the hook 38 is hooked at the central hole of the forging material. By working the winch 35 again to wind up the steel wire rope 36, the forging material can be lifted. When the winch 35 winds up the steel wire rope 36 and under the pulling force of the self-weight of the forging material, the steel wire rope 36 is in a tensioned state. With the rolling support of the roller 373, the L-shaped swing plate 372 receives a reverse acting force, causing the L-shaped swing plate 372 to drive the C-shaped support tooth 374 to rotate counterclockwise, and the elastic support bar 376 is compressed. By making the outer cylindrical surface of the connecting roller 375 contact with the steel wire rope 36, and the two symmetrical connecting rollers 375 form a V shape, the two symmetrical steel wire ropes 36 can be squeezed towards the middle, causing the hook 38 to receive a reverse pulling force and making the hook 38 hook the forging material stably. Under the linear guidance of the linear guide 31, using the mobile trolley 32 as the power, the gantry 33 is driven to move by the mobile trolley 32, so that the forging material can be lifted and the steel wire rope 36 can move from the position of the rectangular notch 48. At the same time, with the forging material moving into the interior of the cylindrical cover 41, the cross-section of the forging material contacts the inner side surface of the opening connecting ring 65. As the forging material continues to move and under the sliding connection of the curved surface slider 63, the forging material is always at the center inside the cylindrical cover 41, not prone to eccentricity and without shaking, which helps to spray and cool the forging material by quenching with the first nozzle 45 and the second nozzle 464. The spring 64 will be compressed under extrusion. When the hook 38 at the central hole of the forging material contacts the scraper 466, as the forging material continues to move, the scraper 466 will receive the pressing force from the hook 38 and, under the elastic support of the elastic piece 465, the scraper 466 will move towards the position close to the round tube 461, making the forging material move smoothly. And as the lifted forging material moves into the interior of the cylindrical cover 41, the end of the round tube 461 far from the speed reducer 462 passes through the central hole of the forging material. Under the elastic support of the elastic piece 465, the edge of the scraper 466 fits against the inner wall of the central hole of the forging material. As the forging material continues to move, the oxide layer impurities on the inner wall of the central hole of the forging material can be scraped off. When the forging moves to the middle inside the cylindrical cover 41, the movement of the trolley 32 is paused. At this time, the staff starts the pump body 42 to work. By making the water inlet of the pump body 42 penetrate the surface of the quenching pool 1 and extend into its interior, the coolant can be sucked out from the interior of the quenching pool 1 through the water inlet of the pump body 42. Under the action of fluid pressure, the coolant enters the interior of the circular water channel 44. Then, through the conveyance of the water pipe 43, the coolant can be sprayed from the first nozzle 45 onto the surface of the forging material at the center inside the cylindrical cover 41. As soon as the coolant sprays onto the surface of the forging material, the heat of the forging material can be absorbed, and the heat is dissipated in a timely manner as the coolant flows downward, thereby cooling the surface of the forging material. Moreover, the water pipe 43 is evenly installed on the outer circular surface of the cylindrical cover 41, and the coolant is sprayed onto the surface of the forging material through the evenly distributed first nozzles 45; Moreover, the staff starts the servo motor 463 to work. By using the rotation of the output end of the servo motor 463 and under the transmission of the transmission 462, the round tube 461 is driven to rotate. And with the rotational connection of the rotational connector 467, the rotation of the round tube 461 is smooth and it is not easy to have the situation of mechanism jamming. As the round tube 461 rotates, the second nozzle 464 can be driven to rotate together. And as the liquid outlet at the top of the pump body 42 conveys the coolant into the interior of the round tube 461, the coolant can be sprayed from the second nozzle 464 onto the inner wall of the central hole of the forging material, thereby cooling the central hole of the forging material and performing spray quenching on the forging material; After the quenching of the forging material is completed, the work of the pump body 42 can be turned off, and the trolley 32 is used to drive the gantry 33 to move in the reverse direction, so that the forging material can be removed from the interior of the cylindrical cover 41. The driving force received by the opening connecting ring 65 disappears, and under the elastic force of the spring 64, the curved surface slider 63 drives the opening connecting ring 65 and the opening extension edge 66 to move together to the side away from the interior of the cylindrical cover 41, making the opening extension edge 66 move linearly, so that the oxide layer debris falling to the bottom of the inner cavity of the cylindrical cover 41 can be scraped, facilitating the oxide layer debris and the coolant to fall from the water leakage hole 47, and then the removed forging material can be put down.
