Description

Technical Field

[0001] The present application relates to the field of cooling forgings, and in particular to an intelligent spray cooling device for heat-treated annular forgings. Background Art

[0002] Ring forgings are a type of forgings that can be seen everywhere in daily life. They are metal billets (excluding plates) that are transformed into ring-shaped objects with appropriate compression force by applying external force according to the requirements of plastic deformation.

[0003] The production process of ring forgings generally includes the steps of marking and blanking, heating and tempering, forging, inspection, heat treatment, rough machining, ultrasonic flaw detection, mechanical property test and final inspection. Among them, heat treatment is a comprehensive process of heating the forging to a predetermined temperature, keeping it warm for a certain period of time, and then cooling it at a predetermined rate to improve the internal structure and performance of the forging.

[0004] At present, a blower is usually used to cool the ring forgings during the cooling process. However, the use of the blower not only generates a large amount of noise, which affects the hearing of the workers, but also fails to accurately control the cooling speed of the ring forgings, thus affecting the quality of the ring forgings. Summary of the invention

[0005] In order to reduce the noise generated when the ring forging is cooled and to control the cooling rate of the ring forging, the present application provides an intelligent spray cooling device for heat-treated ring forgings.

[0006] The present application provides an intelligent spray cooling device for heat-treated annular forgings, which adopts the following technical solution: An intelligent spray cooling device for heat-treated annular forgings comprises an operating platform, a water tank, a water pump, a cooling assembly and a driving assembly, wherein a plurality of support bars are arranged on the operating platform for supporting the annular forgings; the water tank and the water pump are both arranged on one side of the operating platform, the water tank is communicated with the water pump, a control cabinet is arranged on one side of the operating platform, an infrared thermometer is arranged on the control cabinet for detecting the temperature of the annular forgings, and the infrared thermometer is electrically connected to the water pump through a control system; the cooling assembly is arranged on the operating platform, the cooling assembly comprises an inner spray component and an outer spray component, the water pump pumps the water in the water tank to the inner spray component and the outer spray component, the inner spray component is arranged on the inner side of the annular forging, and the outer spray component is arranged on the outer side of the annular forging; the driving assembly is arranged on the top of the operating platform for driving the inner spray component and the outer spray component to rotate.

[0007] By adopting the above technical solution, the heat-treated annular forging is placed on multiple support bars using a lifting device, and the water pump is turned on. The water pump pumps the water in the water tank to the inner spray part and the outer spray part. The inner spray part and the outer spray part spray water mist from the inner side and the outer side of the annular forging to its surface respectively. The noise generated during spraying is small, which greatly reduces the harm to the staff. At the same time, the drive component is started to drive the inner spray part and the outer spray part to rotate, so that the water mist can be evenly sprayed on the surface of the annular forging. When the water vaporizes, it will absorb the heat of the annular forging, so that the annular forging is gradually cooled. The infrared thermometer will monitor the temperature of the surface of the annular forging in real time, and the frequency of the water pump is adjusted according to the temperature to control the size of the spray, so as to achieve the cooling speed of the annular forging.

[0008] Optionally, the external spray component includes a support seat, a rotating ring and a first spray pipe. There are multiple support seats, and the multiple support seats are circumferentially arranged on the top of the operating platform along the axis of the rotating ring. The rotating ring is rotatably connected to the tops of the multiple support seats. The first spray pipe is arranged on the rotating ring and is connected to the water pump.

[0009] By adopting the above technical solution, the water pump is turned on and the first spray pipe sprays toward the surface of the annular forging. At this time, the driving assembly drives the rotating ring to rotate, driving the first spray pipe to rotate, expanding the spraying range of the water mist, so that the annular forging can be evenly cooled.

[0010] Optionally, the inner spray component includes a mounting platform and a second spray pipe, the mounting platform is rotatably connected to the operating platform and is coaxially arranged with the rotating ring, and the second spray pipe is arranged on the top of the mounting platform.

[0011] By adopting the above technical solution, when the water pump is turned on, the second spray pipe sprays from the inside to the surface of the annular forging, and at the same time, the driving component drives the mounting table to rotate, and the mounting table drives the second spray pipe to rotate, thereby further expanding the spraying range of the water mist and covering the surface of the forging with water mist as much as possible, thereby cooling it evenly and quickly.

[0012] Optionally, the driving assembly includes a reduction motor, a driving gear, a driven gear, an internal transmission gear and an external transmission gear. The reduction motor is arranged on the top of the operating platform and is electrically connected to the infrared thermometer through a control system. The driving gear is coaxially fixedly connected to the output shaft of the reduction motor, the driven gear is rotatably connected to the top of the operating platform and is meshed with the driving gear, the internal transmission gear is coaxially fixedly connected to the mounting platform and is meshed with the driven gear, and the external transmission gear is coaxially fixedly connected to the rotating ring and is meshed with the driving gear.

[0013] By adopting the above technical solution, when the infrared thermometer detects that the temperature of the annular forging is high, the reduction motor is started, the output shaft of the reduction motor drives the driving gear to rotate, the driving gear drives the driven gear and the outer transmission gear to rotate, and the driven gear drives the inner transmission gear to rotate, so that the rotating ring and the mounting table rotate with the inner transmission gear and the outer transmission gear respectively, and the first spray pipe and the second spray pipe also rotate synchronously, so that the range of water mist sprayed on the surface of the annular forging is increased, thereby ensuring the cooling speed of the annular forging.

[0014] Optionally, a lifting assembly is provided on the operating platform, and the lifting assembly includes a lifting telescopic rod, a pressing telescopic rod and a pressure plate. The lifting telescopic rod is arranged below the mounting platform in a vertical direction, and the movable end of the lifting telescopic rod is rotatably connected to the bottom of the mounting platform. The pressing telescopic rod is arranged on one side of the lifting telescopic rod in a vertical direction, and the movable end of the pressing telescopic rod is fixedly connected to the pressure plate. The pressure plate is arranged above the operating platform and on one side of the support bar. The rodless cavity of the pressing telescopic rod is communicated with the rodless cavity of the lifting telescopic rod.

[0015] By adopting the above technical solution, when the annular forging is not placed on the support bar, the downward telescopic rod is in an extended state, the horizontal plane of the pressing plate is higher than the horizontal plane of the top of the support bar, and the lifting telescopic rod is in a retracted state, and the horizontal plane of the top of the mounting platform is lower than the top of the operating platform, thereby avoiding damage to the second spray pipe when placing the annular forging. After the annular forging is placed, the pressing plate moves downward under the gravity of the annular forging, pressing the medium in the rodless cavity of the downward telescopic rod into the rodless cavity of the lifting telescopic rod, and the lifting telescopic rod is extended, driving the mounting platform to move up, so that the second spray pipe rises to a specified position, and can spray water mist onto the surface of the annular forging.

[0016] Optionally, two travel switches are provided on the rotating ring, and both of the travel switches are electrically connected to the reduction motor through a control system.

[0017] By adopting the above technical solution, as the rotating ring rotates, one of the travel switches will touch the support seat, and the control system will control the reduction motor to rotate in the opposite direction. When the rotating ring rotates to the point where the other travel switch touches the support seat, the control system will again control the reduction motor to rotate in the opposite direction, so that the rotating ring will reciprocate within a certain angle range, thereby minimizing interference and obstruction of the water pipe connecting the water pump and the first spray pipe to the operation of other parts.

[0018] Optionally, a return spring is provided in the rodless cavity of the downward-pressing telescopic rod.

[0019] By adopting the above technical solution, when the annular forging is cooled to the specified temperature, the annular forging is removed using a lifting equipment, and the downward telescopic rod will extend under the elastic resetting action of the resetting spring, and the medium in the rodless cavity of the lifting telescopic rod enters the rodless cavity of the downward telescopic rod, the lifting telescopic rod contracts, and the mounting platform moves downward to facilitate the placement of the next annular forging.

[0020] Optionally, a water storage chamber is provided in the operating platform, and the top of the operating platform is inclined downward from the edge to the center. A water inlet is provided on the top of the water storage chamber, and the water inlet is provided on a side of the support bar close to the mounting platform. The water storage chamber is connected to the water tank.

[0021] By adopting the above technical solution, the excess water mist sprayed by the first spray pipe and the second spray pipe will flow along the top of the operating platform to the water inlet, and flow into the water storage chamber from the water inlet to be collected. When the water in the water storage chamber accumulates to a certain water level, it will flow back to the water tank and continue to be used for cooling the annular forgings, thereby realizing the recycling of water resources.

[0022] Optionally, at least three positioning rollers are arranged on the top of the operating platform, and the positioning rollers are arranged on a side of the rotating ring away from the mounting platform and are rotatably connected to the rotating ring.

[0023] By adopting the above technical solution, the three positioning rollers are installed on the outer side of the rotating ring, which ensures that the rotating ring can rotate stably and reduces the possibility of the rotating ring being skewed during the rotation process.

[0024] Optionally, a roller wheel is provided on the top of the support seat, and the roller wheel is rotatably connected to the rotating ring.

[0025] By adopting the above technical solution, when the rotating ring rotates, the roller wheel will rotate along its own axis, converting the sliding friction between the rotating ring and the support seat into rolling friction between the rotating ring and the roller wheel, reducing the loss of the rotating ring during operation and extending the service life of the rotating ring.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The temperature of the ring forging is detected by an infrared thermometer, and the power of the water pump can be adjusted to control the spraying amount of water mist, thereby controlling the cooling speed of the ring forging and ensuring the quality of the ring forging; 2. When the annular forging is placed on the support bar, the pressing plate will be pressed down, and the pressing plate will press the medium in the rodless cavity of the downward pressing telescopic rod into the rodless cavity of the lifting telescopic rod. At this time, the mounting block will drive the second spray pipe to move up to the specified spray height to avoid damage to the second spray pipe when placing the annular forging; 3. The rotating ring and the mounting platform will respectively drive the first spray pipe and the second spray pipe to reciprocate within a certain angle range, thereby expanding the spraying range of the water mist, so that the water mist can be evenly sprayed on the surface of the annular forging, thereby prompting the annular forging to cool rapidly.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] Reference Figure 1 The embodiment of the present application discloses an intelligent spray cooling device for heat-treated annular forgings, including an operating platform 1, a water tank 2, a water pump 3, a cooling assembly 4, a driving assembly 5 and a lifting assembly 6. The operating platform 1 is fixedly installed on the ground. In this embodiment, the operating platform 1 is a cylinder, and twelve support bars 11 are fixedly installed on the top of the operating platform 1 by bolts. The twelve support bars 11 are arranged at intervals along the circumferential direction of the axis of the operating platform 1 and are radially arranged to support the annular forgings.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The cooling assembly 4 includes an outer spray member 41 and an inner spray member 42, wherein the outer spray member 41 includes a support seat 411, a rotating ring 412 and a plurality of first spray pipes 413, a plurality of support seats 411 are provided, and are circumferentially arranged along the axis of the rotating ring 412, the support seat 411 is fixedly installed on the top of the operating platform 1 by bolts, and the rotating ring 412 is rotatably connected to the top of the plurality of support seats 411, in order to reduce the friction between the support seat 411 and the rotating ring 412, a roller wheel 4111 is rotatably connected to the top of each support seat 411, and the rotating ring 412 is rotatably connected to the roller wheel 4111. A plurality of first spray pipes 413 are circumferentially installed on the top of the rotating ring 412 along the axis of the rotating ring 412, and are all connected to the water pump 3, and in this embodiment, twelve first spray pipes 413 are provided.

[0032] In order to improve the rotation stability of the rotating ring 412, at least three positioning rollers 7 are arranged on the top of the operating platform 1. The three positioning rollers 7 are all arranged on the side of the rotating ring 412 away from the center of the operating platform 1, and are rotatably connected to the rotating ring 412 to reduce the possibility of the rotating ring 412 being skewed during rotation.

[0033] The inner spray component 42 includes a mounting platform 421 and a plurality of second spray pipes 422. A receiving groove 12 is provided at the center position of the top of the operating platform 1. The mounting platform 421 is a cylinder. The mounting platform 421 is rotatably connected to the receiving groove 12. A plurality of second spray pipes 422 are fixedly installed at the edge of the mounting platform 421 along the circumferential direction of the axis of the mounting platform 421, and are all connected to the water pump 3. In this embodiment, the mounting platform 421 is coaxially arranged with the rotating ring 412, and twelve second spray pipes 422 are provided.

[0034] Use lifting equipment to place the heat-treated annular forging on the support bar 11, turn on the water pump 3, and pump the water in the water tank 2 to the first spray pipe 413 and the second spray pipe 422. The first spray pipe 413 sprays water mist from the outside of the annular forging to the surface of the annular forging, and the second spray pipe 422 sprays water mist from the inside of the annular forging to the surface of the annular forging, which can quickly cool the annular forging and generate very little noise.

[0035] Reference Figure 4The driving assembly 5 includes a reduction motor 51, a driving gear 52, a driven gear 53, an internal transmission gear 54 and an external transmission gear 55. The reduction motor 51 is fixedly mounted on the operating platform 1 in the vertical direction. The driving gear 52 is coaxially fixedly connected to the output shaft of the reduction motor 51. The driven gear 53 is rotatably connected to the top of the operating platform 1 and meshed with the driving gear 52. The internal transmission gear 54 is coaxially fixedly connected to the mounting platform 421 and meshed with the driven gear 53. The external transmission gear 55 is coaxially fixedly connected to the rotating ring 412 and meshed with the driving gear 52.

[0036] Reference Figure 3 and Figure 4 Two travel switches 8 are welded on the rotating ring 412. Both travel switches 8 are electrically connected to the reduction motor 51 through the control system to control the rotation direction of the output shaft of the reduction motor 51. As the rotating ring 412 rotates, one of the travel switches 8 will touch the support seat 411, and the control system will control the reduction motor 51 to rotate in the opposite direction. When the rotating ring 412 rotates to the point where the other travel switch 8 touches the support seat 411, the control system will control the reduction motor 51 to rotate in the opposite direction again, so that the rotating ring 412 reciprocates within a certain angle range, and the water pipe connecting the water pump 3 and the first spray pipe 413 is prevented from interfering with and hindering the operation of other parts.

[0037] It should be noted that, refer to Figure 1 and Figure 4 A control cabinet 9 is also fixedly installed on one side of the operating platform 1. An infrared thermometer 91 is installed on the control cabinet 9 to detect the temperature of the ring forging. The infrared thermometer 91 is electrically connected to the reduction motor 51 through the control system. When the infrared thermometer 91 detects that the temperature of the ring forging is high, the control system starts the reduction motor 51. The output shaft of the reduction motor 51 drives the driving gear 52 to rotate. The driving gear 52 drives the driven gear 53 and the outer transmission gear 55 to rotate. The driven gear 53 drives the inner transmission gear 54 to rotate, so that the rotating ring 412 and the mounting platform 421 rotate with the inner transmission gear 54 and the outer transmission gear 55 respectively, and the first spray pipe 413 and the second spray pipe 422 also rotate synchronously, so that the range of water mist sprayed on the surface of the ring forging is increased to ensure the cooling speed of the ring forging.

[0038] In addition, the infrared thermometer 91 is also electrically connected to the water pump 3 through the control system, and the power of the water pump 3 is adjusted according to the temperature of the ring forging. If it is detected that the temperature of the ring forging is high, the power of the water pump 3 is increased to increase the spraying amount of water mist; when the temperature of the ring forging is reduced, the power of the water pump 3 can be reduced, the spraying amount of water mist can be reduced, and the cooling speed of the ring forging can be controlled to ensure the quality of the ring forging.

[0039] Reference Figure 5The lifting assembly 6 includes a lifting telescopic rod 61, a pressing telescopic rod 62 and a pressing plate 63. The lifting telescopic rod 61 is fixedly installed below the mounting platform 421 in the vertical direction. The movable end of the lifting telescopic rod 61 is rotatably connected to the bottom of the mounting platform 421. There are multiple pressing telescopic rods 62 and pressing plates 63, and the two correspond to each other. In this embodiment, there are four pressing telescopic rods 62 and pressing plates 63. The pressing telescopic rod 62 is embedded in the operating platform 1 in the vertical direction. The movable end of the pressing telescopic rod 62 is welded to the bottom of the pressing plate 63. The pressing plate 63 is located above the operating platform 1. The rodless cavities of the four pressing telescopic rods 62 are all connected to the rodless cavity of the lifting telescopic rod 61. A return spring 621 is arranged in the rodless cavity of the pressing telescopic rod 62. One end of the return spring 621 is fixedly connected to the inner wall of the rodless cavity of the pressing telescopic rod 62, and the other end is fixedly connected to the movable end of the pressing telescopic rod 62.

[0040] When the annular forging is not placed on the support bar 11, the downward telescopic rod 62 is in an extended state, the horizontal plane of the pressing plate 63 is higher than the horizontal plane of the top of the support bar 11, and the lifting telescopic rod 61 is in a retracted state, and the horizontal plane of the top of the mounting platform 421 is lower than the top of the operating platform 1, so as to avoid damage to the second spray pipe 422 when the annular forging is placed. After the annular forging is placed, the pressing plate 63 moves downward under the gravity of the annular forging, and presses the medium in the rodless cavity of the downward telescopic rod 62 into the rodless cavity of the lifting telescopic rod 61. The lifting telescopic rod 61 is extended, driving the mounting platform 421 to move upward, so that the second spray pipe 422 rises to a specified position, and can spray water mist onto the surface of the annular forging. When the annular forging is cooled to the specified temperature, the annular forging is removed using a lifting device, and the downward telescopic rod 62 will extend under the elastic resetting action of the resetting spring 621, and the medium in the rodless cavity of the lifting telescopic rod 61 enters the rodless cavity of the downward telescopic rod 62, the lifting telescopic rod 61 contracts, and the mounting platform 421 moves downward to facilitate the placement of the next annular forging.

[0041] Reference Figure 1 and Figure 5 In addition, a water storage chamber 13 is provided in the operating platform 1, and the water storage chamber 13 is connected to the water tank 2. The top of the operating platform 1 is tilted downward from the edge to the center, and a water inlet is provided at the top of the water storage chamber 13. In this embodiment, the water inlet is located on the side of the support bar 11 close to the mounting platform 421, that is, closer to the center of the operating platform 1. Therefore, the excess water mist sprayed by the first spray pipe 413 and the second spray pipe 422 will flow along the top of the operating platform 1 to the water inlet, and flow into the water storage chamber 13 from the water inlet to be collected. When the water in the water storage chamber 13 accumulates to a certain water level, it will flow back to the water tank 2 and continue to be used for cooling the annular forgings, thereby realizing the recycling of water resources.

[0042] The implementation principle of the intelligent spray cooling device for heat-treated annular forgings in the embodiment of the present application is as follows: the heat-treated annular forgings are placed on the support bar 11 using a hoisting device. When the annular forgings fall, the pressing plate 63 is pressed down, and the medium in the rodless cavity of the downward pressing telescopic rod 62 is pressed into the rodless cavity of the lifting telescopic rod 61. The lifting telescopic rod 61 is extended, driving the mounting platform 421 to move up, so that the second spray pipe 422 rises to the specified position. Turn on the water pump 3, and the water pump 3 delivers the water in the water tank 2 to the first spray pipe 413 and the second spray pipe 422, so that the first spray pipe 413 and the second spray pipe 422 spray water mist from the outside and inside of the annular forging to the surface of the annular forging, respectively, and the noise generated is relatively small.

[0043] When the infrared thermometer 91 detects that the temperature of the ring forging is high, the reduction motor 51 is started, the output shaft of the reduction motor 51 drives the driving gear 52 to rotate, the driving gear 52 drives the driven gear 53 and the outer transmission gear 55 to rotate, and the driven gear 53 drives the inner transmission gear 54 to rotate, so that the rotating ring 412 and the mounting platform 421 rotate with the inner transmission gear 54 and the outer transmission gear 55 respectively, and the first spray pipe 413 and the second spray pipe 422 also rotate synchronously, so that the range of the water mist sprayed on the surface of the ring forging is increased to ensure the cooling speed of the ring forging. When the infrared thermometer 91 detects that the temperature of the ring forging is reduced, the control system will reduce the power of the water pump 3, reduce the spraying amount of water mist, and realize accurate control of the cooling speed of the ring forging. When the annular forging drops to the specified temperature, the control system turns off the reduction motor 51, the water pump 3 is also turned off, and the lifting equipment removes the annular forging. The downward telescopic rod 62 will extend under the elastic resetting action of the resetting spring 621, and the medium in the rodless cavity of the lifting telescopic rod 61 enters the rodless cavity of the downward telescopic rod 62. The lifting telescopic rod 61 contracts, and the mounting platform 421 moves downward to facilitate the placement of the next annular forging.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
