Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal heat treatment, in particular to a temperature control system for cooling a heat-treated workpiece. BACKGROUND

[0002] Heat treatment generally includes three processes of heating, holding and cooling, and cooling of heat treatment usually has air cooling, water cooling, oil cooling and natural cooling, wherein water cooling is mainly used for high-temperature rapid cooling, such as quenching process.

[0003] In order to improve the water cooling effect, a heat treatment cooling device is disclosed in Chinese Patent No. CN111575460A, which comprises a cooling chamber, a moving assembly and a stirrer. The moving assembly drives the workpiece to move in the cooling water, and the stirrer stirs the cooling water. At the same time, the cooling chamber is provided with cooling water by a water pump, so that the cooling water in the cooling chamber can be circulated, and the workpiece can be in contact with other cooling water to ensure the cooling effect.

[0004] In the above scheme, the newly added cooling water in the cooling chamber will be mixed and exchanged with the cooling water heated by the workpiece under the action of the stirrer. Although the newly added cooling water reduces the temperature of the cooling water in the cooling chamber, for a cooling chamber of a large-size workpiece, the total amount of the cooling water in the cooling chamber is much larger than the amount of the newly added cooling water, which leads to slow recovery of the cooling capacity of the cooling water in the cooling chamber, so that the cooling speed of the workpiece after entering the water is slow, thereby resulting in poor rapid cooling effect of the workpiece.

[0031] 1. This application discloses a temperature control system for cooling heat-treated workpieces, comprising a cooling water tank, a moving assembly, a stirring assembly, a water inlet assembly, and a water exchange assembly. By immersing the workpiece at an angle, the workpiece remains in constant contact with unheated cooling water during immersion, improving the cooling effect. Simultaneously, the angled movement of the workpiece helps to break up the vapor film formed on its surface. After the workpiece reaches the center of the water exchange area, the stirring assembly is activated, causing the probe on the water flow support rod to contact the workpiece under the continuous force of the water flow. Then, the electromagnet is de-energized, causing the probe on the gravity support rod to contact the workpiece under the influence of gravity. Under the action of force, it comes into contact with the workpiece. Due to the continuity and gentleness of the water flow force and gravity, there is no need to preset the movement stroke of the probe. The first water pump can spray the cooling water in the water supply chamber to the area around the workpiece. The sprayed cooling water helps to break the vapor film on the surface of the workpiece. The second water pump can discharge the heated cooling water in the cooling chamber into the filter water tank, so that the cooling water around the workpiece can be directly replaced to control the cooling temperature around the workpiece. This improves the cooling recovery ability of the cooling water around the workpiece, thereby ensuring the cooling speed of the workpiece after it enters the water and improving the rapid cooling effect of the workpiece.

[0032] 2. The temperature control system for cooling heat-treated workpieces according to this application further includes a safety component, wherein, when at least one water flow support rod has not slid to the position furthest from the center of the water exchange area, the fixing block can engage the safety block in the safety slot to prevent the workpiece from moving and damaging the elastic telescopic nozzle and probe on the water flow support rod; when the gravity support rod has not slid to the position furthest from the partition, the push plate will be below the connecting plate, and the safety baffle can block the sliding of the first slide plate, making it difficult for the water flow support rod corresponding to the gravity support rod to push the first slide plate to slide, thereby preventing the workpiece from moving and damaging the elastic telescopic nozzle and probe on the gravity support rod.

[0043] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0044] This application discloses a temperature control system for cooling heat-treated workpieces. (Refer to...) Figure 1 and Figure 2 A temperature control system for cooling heat-treated workpieces includes a cooling water tank 1, a moving component 2, a stirring component 3, a water inlet component 4, and a water exchange component 5.

[0045] Reference Figure 2 A partition 11 is fixedly installed inside the cooling water tank 1. The partition 11 divides the internal space of the cooling water tank 1 into two layers: the upper layer is the cooling chamber 12 and the lower layer is the water supply chamber 13. Both the cooling chamber 12 and the water supply chamber 13 are filled with cooling water. The cooling water in the cooling chamber 12 is used to directly cool the workpiece, and the cooling water in the water supply chamber 13 is used to replace the cooling water heated by the workpiece.

[0046] The moving component 2 is installed inside the cooling chamber 12, and multiple sets are arranged around it. The multiple sets of moving components 2 form a water exchange area. The moving component 2 includes a water flow moving part 21 and a gravity moving part 22.

[0047] Reference Figure 3 The water flow moving part 21 includes a water flow support rod 211 and a water flow moving plate 212.

[0048] Reference Figure 2 and Figure 3 The water flow support rod 211 is vertically set and its bottom end is slidably set on the partition plate 11. The sliding direction of the water flow support rod 211 is towards or away from the center of the water exchange area. The water flow moving plate 212 is fixedly connected to the bottom end of the water flow support rod 211 and is inclined relative to the sliding direction of the water flow support rod 211.

[0049] The stirring assembly 3 is set in the water exchange area and is used to stir the cooling water in the water exchange area in both directions to make the cooling water in the cooling chamber 12 uniform. When the stirring assembly 3 stirs the cooling water in the forward direction, the vortex flow of the cooling water applies a driving force to the water flow moving plate 212 toward the center of the water exchange area to drive the water flow support rod 211 to slide toward the center of the water exchange area. When the stirring assembly 3 stirs the cooling water in the reverse direction, the vortex flow of the cooling water applies a driving force to the water flow moving plate 212 away from the center of the water exchange area to drive the water flow support rod 211 to slide away from the center of the water exchange area.

[0050] Reference Figure 3 The gravity-moving part 22 includes a gravity support rod 221, an electromagnet 222, and a magnetic block 223.

[0051] The gravity support rod 221 is horizontally positioned, with one end slidably mounted on the water flow support rod 211. The density of the gravity support rod 221 is greater than that of the cooling water, allowing it to sink in the cooling water in a free state. An electromagnet 222 is fixed to the top of the water flow support rod 211, and a magnetic block 223 is connected to the end of the gravity support rod 221 near the water flow support rod 211. The electromagnet 222 and the magnetic block 223 are positioned opposite each other. When energized, the polarities of the electromagnet 222 and the magnetic block 223 are opposite on the side closest to each other. The electromagnet 222 can drive the gravity support rod 221 to slide upwards through magnetic attraction.

[0052] Reference Figure 4 The water inlet assembly 4 includes a mesh tray 41 and a water inlet section 42.

[0053] Reference Figure 2 and Figure 4 The mesh tray 41 is used to receive the workpiece. The mesh tray 41 is set on the water inlet 42, which is connected to the partition 11. The water inlet 42 is used to drive the mesh tray 41 to discharge water to receive the workpiece. The water inlet 42 is also used to drive the mesh tray 41 to move the workpiece to the center of the water exchange area.

[0054] Reference Figure 2 The water exchange assembly 5 includes a side water exchange section 51, a top water exchange section 52, a bottom water exchange section 53, and a filter section 54.

[0055] Reference Figure 3 , Figure 5 and Figure 6 The side water exchange section 51 and the top water exchange section 52 have the same structure and are provided in multiples. The side water exchange section 51 includes an elastic telescopic nozzle 511, a first water pump head 512 and a probe 513. The bottom water exchange section 53 is provided in multiples. The bottom water exchange section 53 includes a bottom nozzle 531 and a second water pump head 532.

[0056] The elastic telescopic nozzles 511 of the side water exchange section 51 are connected to the water flow support rod 211 in a corresponding manner. The elastic telescopic nozzles 511 of the top water exchange section 52 are connected to the gravity support rod 221 in a corresponding manner. The first water suction head 512 is connected to the elastic telescopic nozzle 511. One end of the probe 513 is connected to the elastic telescopic nozzle 511, and the other end is used to abut against the workpiece. The bottom nozzle 531 is fixed to the mesh tray 41, and the second water suction head 532 is fixed to the bottom nozzle 531.

[0057] Reference Figure 2 , Figure 5 and Figure 6Both the elastic telescopic nozzle 511 and the bottom nozzle 531 are connected to a water spray hose 514. The other end of all the water spray hoses 514 is connected to a first water pump 5141 via a pipeline. The inlet of the first water pump 5141 is connected to the water supply chamber 13. The first water pump 5141 is used to draw cooling water from the water supply chamber 13. Both the first water suction head 512 and the second water suction head 532 are connected to a water suction hose 515. The other end of all the water suction hoses 515 is connected to a second water pump 5151 via a pipeline. The outlet of the second water pump 5151 is connected to a filter section 54. The filter section 54 is connected to the water supply chamber 13. The filter section 54 is used to filter and cool the cooling water discharged from the water suction hoses 515. The second water pump 5151 is used to draw heated cooling water from the cooling chamber 12.

[0058] Specifically, the connecting pipes between the first water pump 5141 and all the spray hoses 514 are not shown in the figure, and the connecting pipes between the second water pump 5151 and all the pumping hoses 515 are not shown in the figure.

[0059] In use, after the workpiece is heated, the water inlet assembly 4 moves the workpiece to the middle position of the water exchange area. The stirring assembly 3 stirs the cooling water in the cooling chamber 12 in a positive direction. The stirring assembly 3 causes the cooling water to vortex. The vortex-flowing cooling water can mix the cooling water heated by the workpiece and the cooling water not heated by the workpiece. At the same time, the vortex-flowing cooling water can drive the water flow moving plate 212 to move with the power of the water flow, so that the water flow moving plate 212 can drive the water flow support rod 211 to slide towards the workpiece until the probe 513 on the water flow support rod 211 touches the surface of the workpiece, so that the electromagnet 222 is de-energized. The gravity support rod 221 slides towards the workpiece under the action of gravity until the probe 513 on the gravity support rod 221 touches the surface of the workpiece. The elastic telescopic nozzle 511 buffers the contact reaction force of the probe 513 through elastic deformation.

[0060] Both water flow force and gravity are continuous driving forces. After the probe 513 comes into contact with the workpiece, the water flow force and gravity will continue to act on the probe 513. However, neither the water flow force nor gravity is likely to damage the elastic telescopic nozzle 511 and the probe 513. The continuous driving force of the water flow force and gravity on the probe 513 will only stabilize the contact state between the probe 513 and the workpiece. Since there is no need to consider the removal of the water flow force and gravity, the sliding stroke of the water flow support rod 211 and the gravity support rod 221 does not need to be preset in advance. Therefore, the moving displacement of the probe 513 does not need to be preset in advance according to the shape and size of the workpiece.

[0061] The first water pump 5141 draws cooling water from the water supply chamber 13, allowing the cooling water in the water supply chamber 13 to be sprayed out from the elastic telescopic nozzle 511 and the bottom nozzle 531, so that the cooling water in the water supply chamber 13 can be sprayed directly onto the surface of the workpiece at a position close to the workpiece. The second water pump 5151 draws cooling water heated by the workpiece from the cooling chamber 12 through the first water suction head 512 and the second water suction head 532, so that the heated cooling water can be filtered and cooled by the filter section 54 and then flow back into the water supply chamber 13, so that the cooling water around the workpiece can be directly replaced, thereby controlling the cooling temperature around the workpiece and improving the cooling recovery capacity of the cooling water around the workpiece, thereby improving the cooling speed of the workpiece after entering the water.

[0062] The probe 513 can limit the distance between the elastic telescopic nozzle 511 and the workpiece surface, so that the cooling water flow sprayed by the elastic telescopic nozzle 511 can meet the needs of rapid cooling of the workpiece, and will not cause cracks on the workpiece surface during cooling due to the cooling water flow being too close to the workpiece.

[0063] The cooling water sprayed from the elastic telescopic nozzle 511 and the bottom nozzle 531 can impact the surface of the workpiece. The impacting cooling water can break the vapor film formed on the surface of the workpiece during the initial cooling, thereby improving the initial cooling effect of the workpiece. Furthermore, the impact force of the cooling water sprayed from the elastic telescopic nozzle 511 on the workpiece is less than the driving force of the vortex water flow on the water flow moving plate 212, and the impact force of the cooling water sprayed from the elastic telescopic nozzle 511 on the workpiece is less than the gravity of the gravity support rod 221.

[0064] Since only the cooling water around the workpiece is replaced, the amount of cooling water replaced is greatly reduced compared to replacing the cooling water in the entire cooling chamber 12, thereby reducing the amount of cooling water needed to restore cooling capacity and reducing the cooling energy consumption of the filter section 54.

[0065] Based on the above analysis, by directly replacing the cooling water around the workpiece, the cooling capacity of the cooling water around the workpiece can be quickly restored, the cooling temperature of the workpiece can be controlled, the cooling speed of the workpiece after immersion in water can be guaranteed, and the rapid cooling effect of the workpiece after immersion in water can be improved.

[0066] Among them, reference Figure 3 and Figure 5The elastic telescopic nozzle 511 includes a fixed tube 5111, a movable tube 5112, and a nozzle spring 5113. The fixed tube 5111 is connected to the water flow support rod 211 or the gravity support rod 221. The fixed tube 5111 is connected to the water spray hose 514. The first water suction head 512 is fixedly connected to the fixed tube 5111. The movable tube 5112 is slidably inserted inside the fixed tube 5111. The nozzle spring 5113 is fixedly connected between the movable tube 5112 and the fixed tube 5111. The nozzle spring 5113 is used to make the movable tube 5112 slide elastically relative to the fixed tube 5111. The probe 513 is fixedly connected to the movable tube 5112.

[0067] Reference Figure 1 and Figure 5 To control the replacement rate of cooling water around the workpiece based on the ambient temperature, a water temperature sensor 516 is fixedly mounted on probe 513. The water temperature sensor 516 is located in the middle of probe 513 and outputs a first temperature signal of the cooling water near the workpiece. A first electrically controlled valve 5142 is installed on the spray hose 514, and a second electrically controlled valve 5152 is installed on the suction hose 515. All water temperature sensors 516, all first electrically controlled valves 5142, and all second electrically controlled valves 5152 are electrically connected to a controller 55. The controller 55 responds to the first temperature signal from the water temperature sensor 516 and controls the opening degree of the corresponding first and second electrically controlled valves 5142 and 5152. A higher first temperature signal results in a larger opening degree for the first and second electrically controlled valves 5142 and 5152, respectively. The controller 55 is fixed to the outer wall of the cooling water tank 1.

[0068] The opening degree of the first solenoid valve 5142 and the second solenoid valve 5152 is controlled by the temperature of the cooling water around the workpiece, so that the spraying and suction volume of the cooling water around the workpiece can be adjusted according to the temperature of the cooling water, thereby further improving the cooling effect of the workpiece.

[0069] Reference Figure 3 and Figure 5 In order to adjust the position of the elastic telescopic nozzle 511 according to the shape and size of the workpiece, the elastic telescopic nozzle 511 is connected to a first electric cylinder 517. The fixed end of the first electric cylinder 517 is fixed to the water flow support rod 211 or the gravity support rod 221, and the movable end of the first electric cylinder 517 is connected to the elastic telescopic nozzle 511. The first electric cylinder 517 can drive the elastic telescopic nozzle 511 to move, so as to adjust the position of the elastic telescopic nozzle 511, so that the probe 513 can stably abut against the workpiece of different shapes.

[0070] Specifically, refer to Figure 2The filtration unit 54 includes a water tank 541, a filter screen 542, and a cooler 543.

[0071] The filter screen 542 is inclinedly installed inside the filter water tank 541. The cooler 543 is installed inside the filter water tank 541 and located below the filter screen 542. The cooler 543 is used to cool the cooling water in the filter water tank 541. The filter water tank 541 is connected to the water supply chamber 13. The outlet of the second water pump 5151 is connected to the filter water tank 541.

[0072] The cooling water pumped by the second water pump 5151 first flows through the filter screen 542. The inclined filter screen 542 can filter the cooling water and is not easy to clog. The cooler 543 can cool and lower the temperature of the filtered cooling water so that the cooling water pumped from the cooling chamber 12 can restore its cooling capacity. The cooled water that has restored its cooling capacity can flow back into the water supply chamber 13, so that the cooling water can be recycled. Since the cooling water that is replaced is only the cooling water around the workpiece, compared with replacing the cooling water in the cooling chamber 12, the circulation volume of the cooling water is greatly reduced, so that the cooling water required by the cooler 543 is significantly reduced, thereby significantly reducing the energy consumption of the cooling water in the circulation process.

[0073] Reference Figure 4 and Figure 7 In order to enable the mesh tray 41 to support workpieces of different sizes, multiple telescopic support rods 411 are arranged around the mesh tray 41. The fixed end of the telescopic support rod 411 is fixed to the mesh tray 41. A second electric cylinder 412 is provided on the telescopic support rod 411. The fixed end of the second electric cylinder 412 is fixed to the fixed end of the telescopic support rod 411, and the movable end of the second electric cylinder 412 is fixed to the movable end of the telescopic support rod 411. Multiple bottom water exchange parts 53 are also provided on the movable end of the telescopic support rod 411.

[0074] The second electric cylinder 412 can drive the telescopic support rod 411 to extend and retract, thereby adjusting the length of the telescopic support rod 411. By adjusting the length of the telescopic support rod 411, the mesh tray 41 can support workpieces of different sizes.

[0075] Reference Figure 1 and Figure 6 To accurately measure the cooling temperature of the workpiece surface, a third electric cylinder 413 is fixedly connected to the mesh tray 41. A workpiece temperature sensor 414 is fixedly connected to the movable end of the third electric cylinder 413, directly facing the mesh on the mesh tray 41. The workpiece temperature sensor 414 outputs a second temperature signal from the workpiece surface. The workpiece temperature sensor 414 is electrically connected to a display screen 415, which digitally displays the second temperature signal. The display screen 415 is fixed to the outer wall of the cooling water tank 1.

[0076] After the workpiece has cooled for a period of time, the third electric cylinder 413 can drive the workpiece temperature sensor 414 to move so that the workpiece temperature sensor 414 can pass through the mesh of the mesh tray 41 and come into contact with the workpiece surface. After the workpiece temperature sensor 414 measures the temperature of the workpiece surface, the workpiece temperature sensor 414 can display the measured second temperature signal on the display screen 415 so that the worker can accurately know the cooling status of the workpiece.

[0077] Specifically, refer to Figure 4 The water inlet section 42 includes a water inlet slider 421, a telescopic push rod 422, a water inlet support block 423, and a water inlet hydraulic cylinder 424.

[0078] Reference Figure 2 and Figure 4 The water inlet slider 421 is slidably mounted on the partition plate 11. The movable end of the telescopic push rod 422 is fixedly connected to the water inlet slider 421, and the fixed end of the telescopic push rod 422 is fixedly connected to the mesh tray 41. The water inlet support block 423 is fixedly connected to the partition plate 11, and the water inlet support block 423 is provided with a displacement inclined surface 4231. The water inlet hydraulic cylinder 424 is fixedly connected to the partition plate 11, and the movable end of the water inlet hydraulic cylinder 424 is fixedly connected to the water inlet slider 421. When the water inlet slider 421 slides to the position of the water inlet support block 423, the displacement inclined surface 4231 can push the telescopic push rod 422 to extend, so that the mesh tray 41 is removed from the surface of the cooling water.

[0079] Among them, reference Figure 4 and Figure 6 To make it easier for the displacement ramp 4231 to push the telescopic push rod 422 to extend, a matching ramp 4221 adapted to the displacement ramp 4231 is provided on the fixed end of the telescopic push rod 422; to make the driving force applied by the water inlet support block 423 to the telescopic push rod 422 more stable, two water inlet support blocks 423 are symmetrically arranged on both sides of the water inlet slide rail 14; to enhance the connection strength between the mesh tray 41 and the telescopic push rod 422, multiple reinforcing rods 4222 are fixed between the fixed end of the telescopic push rod 422 and the mesh tray 41; a temperature measuring groove 4223 for accommodating the third electric cylinder 413 and the workpiece temperature sensor 414 is provided on the fixed end of the telescopic push rod 422.

[0080] The water inlet hydraulic cylinder 424 can drive the water inlet slider 421 from the position of receiving the workpiece at the water outlet to the center position of the water exchange area. When the water inlet slider 421 slides to the projection position of the top of the displacement ramp 4231 on the water inlet slide rail 14, the displacement ramp 4231 can drive the telescopic push rod 422 to extend to its maximum length. At this time, the mesh tray 41 can be pushed out of the cooling water surface so that the workpiece can be placed on the mesh tray 41. During the process of the water inlet slider 421 sliding to the center position of the water exchange area, the fixed end of the telescopic push rod 422 will slide along the displacement ramp 4231, so that the workpiece can first enter the cooling water at an angle and then move horizontally to the center position of the water exchange area. This allows the workpiece to contact the cooling water surface of different areas during the water inlet process, so that the workpiece can always be in contact with the unheated cooling water when entering the water, thus improving the cooling effect of the workpiece when entering the water.

[0081] Reference Figure 3 , Figure 5 and Figure 6 To prevent the workpiece from colliding with the probe 513 when it is removed from the water, the temperature control system for cooling heat-treated workpieces in this application also includes a safety component 6, which includes a safety block 61 and a first safety part 62.

[0082] Reference Figure 2 and Figure 4 The water inlet slider 421 is slidably mounted on the water inlet slide rail 14 fixed on the partition plate 11. The water inlet slide rail 14 not only provides a sliding track for the water inlet slider 421, but also provides a stirring space for the stirring assembly 3.

[0083] Reference Figure 4 and Figure 6 The safety block 61 is slidably connected to the sleeve 15 fixed on the water inlet slide rail 14. The safety block 61 is located at the center of the water exchange area. The water inlet slider 421 is provided with a safety slot 4211 for engaging the safety block 61. A release spring 611 is fixed between the safety block 61 and the sleeve 15. The release spring 611 is used to drive the safety block 61 out of the safety slot 4211. When the safety block 61 is inserted into the safety slot 4211, the safety block 61 can restrict the water inlet slider 421 from sliding relative to the water inlet slide rail 14.

[0084] Reference Figure 2 and Figure 3 The first safety part 62 is provided with multiple parts, each corresponding to a water flow support rod 211. Multiple movable slide rails 16 corresponding to each water flow support rod 211 are fixedly connected to the partition plate 11. The ends of the water flow support rods 211 are slidably connected to the movable slide rails 16. The movable slide rails 16 not only provide a sliding track for the water flow support rods 211, but also provide a stirring space for the stirring assembly 3. The first safety part 62 includes a fixing block 621, a first connecting rod 622, and a first sliding plate 623.

[0085] Reference Figure 3 and Figure 8 The fixed card block 621 is provided with an insertion ramp 6211. The fixed card block 621 is used to be inserted into the fixed card slot 612 opened on the safety card block 61 through the insertion ramp 6211. When the fixed card block 621 is inserted into the fixed card slot 612, the safety card block 61 is inserted into the safety card slot 4211.

[0086] Reference Figure 3 One end of the first connecting rod 622 is fixedly connected to the fixed block 621, and the other end is fixedly connected to the first sliding plate 623. The first connecting rod 622 is slidably connected to the movable slide rail 16, and the first sliding plate 623 is slidably connected to the movable slide rail 16 and is located at the end of the movable slide rail 16 away from the center of the water exchange area.

[0087] Reference Figure 3 and Figure 8 A first safety spring 6231 is fixed between the first slide plate 623 and the movable slide rail 16. The first safety spring 6231 is used to drive the fixed block 621 to insert into the fixed slot 612. When the water flow support rod 211 slides to the position furthest from the center of the water exchange area, the water flow support rod 211 drives the first slide plate 623 to disengage the fixed block 621 from the fixed slot 612. When the water flow support rod 211 slides toward the center of the water exchange area, the water flow support rod 211 releases the driving force on the first slide plate 623.

[0088] After the water flow support rod 211 slides toward the workpiece, the first safety spring 6231 can drive the first slide plate 623 to slide. The first slide plate 623 can drive the fixed block 621 to slide through the first connecting rod 622. The fixed block 621 is inserted into the fixed slot 612 of the safety block 61 through the insertion inclined surface 6211. At the same time, the fixed block 621 drives the safety block 61 to slide through the insertion inclined surface 6211, so that the safety block 61 can be inserted into the safety slot 4211. The safety block 61 can restrict the sliding of the water inlet slider 421 relative to the water inlet slide rail 14 through the safety slot 4211. When at least one water flow support rod 211 has not slid to the position furthest from the center of the water exchange area, the safety block 61 cannot disengage from the safety slot 4211, making it difficult for the workpiece to move and damage the elastic telescopic nozzle 511 and probe 513 on the water flow support rod 211.

[0089] Furthermore, referring to Figure 3 and Figure 6 The safety component 6 also includes a second safety unit 63, which includes a safety baffle 631, a second connecting rod 632, and a second sliding plate 633.

[0090] Reference Figure 3The safety baffle 631 is located on the side of the first slide plate 623 near the first safety spring 6231. The safety baffle 631 is slidably connected to the movable slide rail 16. A connecting plate 6311 is fixedly connected to the safety baffle 631. A baffle spring 6312 is fixed between the connecting plate 6311 and the movable slide rail 16. The baffle spring 6312 is used to drive the safety baffle 631 to block the sliding of the first slide plate 623.

[0091] Reference Figure 2 and Figure 3 The second connecting rod 632 is vertically arranged. One end of the second connecting rod 632 near the movable slide rail 16 is fixedly connected to an inclined push plate 6321, and the other end is fixedly connected to a second sliding plate 633. The second sliding plate 633 is slidably connected to the water flow support rod 211. A second safety spring 6331 is fixed between the second sliding plate 633 and the water flow support rod 211. The second safety spring 6331 is used to drive the push plate 6321 to be positioned below the connecting plate 6311. When the gravity support rod 221 slides to... When the position furthest from the partition 11, the gravity support rod 221 drives the push plate 6321 to move upward, so that the connecting plate 6311 is located on the path of the push plate 6321 moving with the water flow support rod 211. At this time, the inclined push plate 6321 can drive the connecting plate 6311 to slide down after approaching the connecting plate 6311. When the gravity support rod 221 fails to slide to the position furthest from the partition 11, the inclined push plate 6321 can move below the connecting plate 6311 after approaching the connecting plate 6311.

[0092] After the gravity support rod 221 slides toward the workpiece, the second safety spring 6331 can drive the second slide plate 633 to slide. The second slide plate 633 can drive the push plate 6321 to move through the second connecting rod 632, so that the push plate 6321 moves below the connecting plate 6311. In this state, the safety baffle 631 can block the first slide plate 623 from sliding. Even if the water flow support rod 211 slides to the first slide plate 623, it is difficult to drive the first slide plate 623 to slide. That is, when the gravity support rod 221 has not slid to the position furthest from the partition 11, the water flow support rod corresponding to the gravity support rod 221... 211 makes it difficult to drive the fixed block 621 out of the fixed slot 612, making it difficult for the workpiece to move and damage the elastic telescopic nozzle 511 and probe 513 on the gravity support rod 221; when the gravity support rod 221 slides to the position furthest from the partition 11, the gravity support rod 221 can drive the push plate 6321 to move upward, so that the push plate 6321 can drive the connecting plate 6311 to move downward when sliding with the water flow support rod 211, so as to release the obstruction effect of the safety baffle 631 on the first slide plate 623, so that the water flow support rod 211 can drive the fixed block 621 out of the fixed slot 612.

[0093] Specifically, refer to Figure 2The stirring assembly 3 includes a first motor 31, a first stirring head 32, a second motor 33, and a second stirring head 34.

[0094] Reference Figure 2 and Figure 3 The first motor 31 is located at the center of the water exchange area and is fixedly connected to the partition 11. The first motor 31 is installed inside the water supply chamber 13, and the output shaft of the first motor 31 rotates through the partition 11. The first stirring head 32 is fixedly connected to the output shaft of the first motor 31. The second motor 33 is located at the top of the water exchange area and is coaxial with the first motor 31. The second motor 33 is fixedly connected to the cooling water tank 1, and the second stirring head 34 is fixedly connected to the output shaft of the second motor 33. The first stirring head 32 and the second stirring head 34 have the same direction of rotation. The second stirring head 34 is immersed in the cooling water. The water flow support rod 211 and the gravity support rod 221 are both located between the first stirring head 32 and the second stirring head 34.

[0095] The first motor 31 drives the first stirring head 32 to rotate, and the second motor 33 drives the second stirring head 34 to rotate. With the first stirring head 32 and the second stirring head 34 rotating in the same direction, the cooling water in the water exchange area can flow in the form of a vortex to mix the cooling water in the water exchange area and drive the water flow moving plate 212 to move.

[0096] It should be noted that all electrical components involved in this application that operate in cooling water are waterproofed. The specific waterproofing measures are existing technologies and will not be described in detail in this application.

[0097] The implementation principle of the temperature control system for cooling heat-treated workpieces in this application embodiment is as follows: During use, the water inlet hydraulic cylinder 424 drives the water inlet slider 421 to slide, and the fixed end of the telescopic top rod 422 slides along the displacement inclined surface 4231, so that the workpiece enters the water obliquely and moves to the center position of the water exchange area. The stirring assembly 3 drives the cooling water to vortex flow. The vortex water flow mixes with the cooling water in the water exchange area and applies a driving force to the water flow moving plate 212. The water flow moving plate 212 drives the water flow support rod 211 to slide towards the workpiece, so that the probe 513 on the water flow support rod 211 can be elastically buffered after... When the probe 513 on the gravity support rod 221 comes into contact with the workpiece, the electromagnet 222 is de-energized, and the gravity support rod 221 slides down toward the workpiece under the action of gravity, so that the probe 513 on the gravity support rod 221 can come into contact with the workpiece after elastic buffering. The first water pump 5141 sprays the cooling water in the water supply chamber 13 onto the workpiece from the elastic telescopic nozzle 511 and the bottom nozzle 531. The second water pump 5151 draws the heated cooling water around the workpiece into the filter water tank 541, so that the cooling water around the workpiece can be directly replaced, ensuring the cooling speed of the workpiece after entering the water and improving the rapid cooling effect of the workpiece.

[0098] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
