Description

Technical Field

[0002] With the continuous development of mechanical transmission and automation technology, screw rods are more and more widely used in precision equipment. Therefore, the requirements for the hardness, wear resistance, mechanical properties, etc. of screw rods are also gradually increasing. In order to improve the surface strength and mechanical properties of the screw rods during processing, quenching equipment is usually used to quench the screw rods. However, during the quenching heating process of the screw rod by the existing quenching equipment, the oxygen in the air easily undergoes an oxidation reaction with the iron in the screw rod heated to a high state to generate oxide scale, which not only reduces the uniformity of the subsequent quenching cooling of the screw rod surface by the equipment, but also reduces the uniformity of the quenching cooling of the inner and outer layers of the screw rod by the equipment to a certain extent, thereby reducing the quenching processing effect of the equipment on the screw rod, and ultimately leading to a decrease in the processing quality of the screw rod.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 19 A screw quenching device includes a support frame 1 and a screw 3. A protection box 2 is fixedly installed on the support frame 1. A spray assembly 4 is arranged in the protection box 2. A positioning assembly 7 is arranged on the support frame 1.

[0021] like Figure 1 - Figure 3 , Fig.19 As shown, a driving system 8 is installed on the support frame 1, a pushing device 9 that cooperates with the driving system 8 is installed on the support frame 1, a unloading system 10 is installed on the support frame 1, a loading system 11 is installed on the support frame 1, and a heating device 12 is fixedly installed on the inner wall of the protective box 2.

[0022] When the device is needed to perform quenching processing on the screw rod 3, the screw rod 3 is first transported to the drive system 8 through the operation of the feeding system 11, and then the drive system 8 and the pushing device 9 are started in sequence. The operation of the drive system 8 drives the screw rod 3 to rotate continuously, and the operation of the pushing device 9 pushes the screw rod 3 to move to the left (such as Figure 1 In the direction shown), when the screw rod 3 completes the quenching process inside the protective box 2 and is moved to the right side of the driving system 8 as a whole under force, the screw rod 3 after processing can be collected by the operation of the unloading system 10.

[0023] The driving system 8, the pushing device 9, the unloading system 10, the loading system 11 and the heating device 12 are all existing equipment, and their specific working principles and internal components are all existing mature technologies, which will not be further elaborated here.

[0024] like Figure 1 - Figure 8 As shown, the spray assembly 4 includes a box body 42 fixedly mounted on the inner top wall of the protective box 2, an oxygen absorption component is installed between the box body 42 and the protective box 2, a temperature control cover 410 is fixedly mounted on the inner bottom wall of the box body 42, an adjustment component is installed on the temperature control cover 410, a cleaning assembly 5 is arranged at the lower end of the box body 42, and a jet assembly 6 is arranged at the lower end of the box body 42.

[0025] The oxygen absorption component includes a water pipe 41 fixedly connected to the upper end of the protection box 2, a servo motor 45 is fixedly installed on the inner top wall of the protection box 2, a rotating shaft 46 is fixedly installed on the driving end of the servo motor 45, a linearly evenly distributed stirring member 47 is fixedly installed on the rotating shaft 46, a water stirring plate 411 is fixedly installed on the rotating shaft 46, and two water stirring plates 411 are provided. An exhaust fan 48 is fixedly installed on the protection box 2, an oxygen absorption tube 49 is fixedly connected to the exhaust fan 48, and one end of the oxygen absorption tube 49 is sealed and passed through and fixedly installed on the box body 42.

[0026] The regulating component includes a drain port 414 provided on the temperature control cover 410. There are two drain ports 414. A conduit 43 is fixedly installed on each of the two drain ports 414. Both conduits 43 are sealed and penetrate and are fixedly installed on the box body 42. The lower ends of the two conduits 43 are fixedly connected to a spray pipe 44. The temperature control cover 410 is provided with an annular slide groove 413 connected with two drain ports 414, and a sealing plate 412 is sealingly and slidably installed on the annular slide groove 413. There are two sealing plates 412, and both sealing plates 412 are provided with a slot 415. The two water stirring plates 411 are rotatably installed with a spring pusher 416 that matches the corresponding slot 415.

[0027] During operation, the temperature control cover 410 can adjust the temperature of the water entering the temperature control cover 410 according to the water temperature required for quenching and cooling the high-temperature screw 3 of the equipment. Its specific working principle and components are all corresponding technologies and will not be further elaborated here.

[0028] When the feeding system 11 conveys the screw rod 3 that needs to be quenched to the top of the driving system 8, water is first continuously conveyed to the inside of the temperature control cover 410 through the water pipe 41 through the existing water supply equipment, and in this process, the exhaust fan 48 is started. The operation of the exhaust fan 48 will continuously extract the gas inside the box 42 and the temperature control cover 410 through the oxygen absorption pipe 49. When the pressure inside the box 42 and the temperature control cover 410 continues to decrease, the solubility of the dissolved gas in the water body will also decrease accordingly, which can help to promote the continuous escape of gas (such as oxygen, carbon dioxide, etc.) in the water body.

[0029] When the equipment performs quenching processing on the screw rod 3, the heating device 12 usually quickly heats the screw rod 3 to 800 to 900 degrees, or even higher. In order to ensure the quenching processing effect of the screw rod 3, the high-temperature screw rod 3 is usually sprayed with water for quenching cooling after a few seconds after the screw rod 3 is heated. When the water body sprays the high-temperature screw rod 3, the oxygen dissolved in the water body is easy to react violently with the iron in the screw rod 3 in the high-temperature state. The oxygen in the water body will react violently with the oxygen in the water body to finally generate iron oxide, that is, oxide scale. At the same time, in the initial stage of quenching and cooling the screw rod 3, the surface temperature of the screw rod 3 is much higher than the boiling point of water, so the water will quickly gasify on the surface of the screw rod 3 to form water vapor, and these water vapors will also react with iron to generate oxide scale; The oxide scale itself has poor thermal conductivity. When the two spray pipes 44 cooperate to spray water quenching and cooling the surface of the screw rod 3, the water needs to pass through the oxide scale covering the surface of the screw rod 3 before cooling the screw rod 3. Therefore, the oxide scale attached to the surface of the screw rod 3 will reduce the quenching of the screw rod 3 by the equipment, as well as the uniformity of the overall spray quenching cooling of the screw rod 3 by the equipment, and reduce the effect of the final quenching processing of the screw rod 3. Therefore, by removing oxygen from the water body, the generation of oxide scale on the surface of the screw rod 3 during the subsequent water spray quenching cooling of the high-temperature screw rod 3 by the equipment can be effectively reduced, which helps to improve the uniformity and effect of the subsequent overall quenching cooling of the screw rod 3 by the equipment.

[0030] At the same time, while the water pipe 41 is continuously conveying water to the temperature control cover 410, the servo motor 45 is started. At this time, the operation of the servo motor 45 drives the plurality of stirring members 47 and the two stirring plates 411 to rotate counterclockwise around the rotating shaft 46 to stir the water inside the temperature control cover 410 (such as Figure 5 In the direction shown), it can effectively accelerate the escape rate of oxygen molecules in the water body, and at the same time, when the temperature control cover 410 is running to adjust the temperature of the collected water body inside, it can improve the uniformity of the water body temperature, which can help to further improve the subsequent water spray quenching cooling effect of the high-temperature screw rod 3 of the equipment.

[0031] At the same time, through Figure 6It can be seen that in the initial state, the blocking area of ​​the left blocking plate 412 on the corresponding drain port 414 is greater than the blocking area of ​​the right blocking plate 412 on the corresponding drain port 414, that is, the subsequent water delivery amount of the right drain port 414 to the inside of the corresponding conduit 43, that is, the water spraying amount of the right spray pipe 44, is greater than the water spraying amount of the left spray pipe 44 (combined with Figure 5 and Figure 6 direction shown).

[0032] The two spray pipes 44 cooperate to repeatedly spray and quench the screw rod 3, which can effectively improve the quenching and cooling effect of the screw rod 3. When the high-temperature screw rod 3 is forced to move to the lower end of the right spray pipe 44 (such as Figure 5 In the direction shown), by opening the valves on the two conduits 43 (not shown in the figure), the right spray pipe 44 starts to spray quench and cool the screw rod 3, causing the surface temperature of the screw rod 3 (i.e., the outer layer of the screw rod 3) to drop rapidly, while the internal temperature is still very high. Since the heat inside the screw rod 3 takes a certain amount of time to be transferred to the outer layer of the screw rod 3 by heat conduction and carried away by the water body, and the thermal conductivity of the material is limited, it is easy to cause the heat dissipation speed of the outer layer of the screw rod 3 to be faster than the heat dissipation speed of the inner layer of the screw rod 3. If the two spray pipes 44 use the same water spraying volume, it is easy to increase the temperature difference between the outer layer and the inner layer of the screw rod 3. This temperature difference is easy to cause the screw rod 3 to generate a large thermal stress, and it is easy to cause the screw rod 3 to crack under the action of thermal stress, thereby reducing the mechanical strength of the screw rod 3 after the final quenching process.

[0033] By gradually reducing the water spraying amount of the two spray pipes 44, the larger water spraying amount of the right spray pipe 44 can prompt the surface of the high-temperature screw rod 3 to cool rapidly, so that its temperature drops rapidly, which is beneficial to the transformation of the austenite of the screw rod 3 to martensite, ensuring the ultimate use strength of the screw rod 3. As the screw rod 3 continues to move to the left (such as Figure 5 In the direction shown), the heat inside the screw rod 3 is gradually transferred to the outer layer of the screw rod 3. When the screw rod 3 moves to the lower end of the left spray pipe 44, the smaller water spray volume through the left spray pipe 44 can reduce the cooling speed of the water body on the surface of the screw rod 3 (at the same time, the moving speed of the screw rod 3 can be reduced by reducing the moving speed of the pushing device 9 to slow down the moving speed of the screw rod 3, ensuring that the device has enough time to spray quench and cool the screw rod 3), allowing the heat inside the screw rod 3 to have enough time to transfer out, thereby helping to reduce the temperature difference between the inner and outer layers of the screw rod 3, helping to reduce the growth rate of thermal stress, and avoiding defects such as cracks or deformation in the screw rod 3 caused by excessive thermal stress, thereby improving the effect of the equipment on quenching and cooling the screw rod 3.

[0034] At the same time, if the drainage volume of the two drainage ports 414 needs to be increased as required, the servo motor 1 45 can be reversed to drive the two water stirring plates 411 to rotate clockwise around the rotating shaft 46 (such as Figure 6 When the spring pushers 416 on the two water stirring plates 411 are rotated and engaged with the corresponding slots 415, the two water stirring plates 411 will push the two blocking plates 412 to rotate clockwise together through the corresponding spring pushers 416 and the slots 415, so as to gradually reduce the blocking area of ​​the left and right blocking plates 412 on the corresponding drain outlets 414 (such as Figure 6 In the direction shown), the effect of increasing the drainage volume of the two drainage ports 414 helps to improve the applicable scope of the equipment (the screw rod 3 of different materials or different quenching and cooling processing requirements require different water spray volumes for water spray quenching and cooling the screw rod 3).

[0035] At the same time, when the heating device 12 heats the screw rod 3 to a high temperature, the activity of the iron atoms, the main component of the screw rod 3, will increase accordingly, and it is easy to react with oxygen in the air to generate oxide scale. When the two spray pipes 44 spray the surface of the screw rod 3 during the quenching cooling process, the impact force generated can blow off the oxide scale covering the surface of the screw rod 3 to a certain extent. At this time, the two inclined spray pipes 44 (from Figure 5 As can be seen in the figure, the oxide scale on the surface of the screw rod 3 can be effectively prevented from falling off, and the nozzles on the two spray pipes 44 are blocked, which can effectively ensure the smoothness of the continuous water spraying of the two spray pipes 44.

[0036] like Figure 5 , Fig. 9 - Fig.13 As shown, the cleaning assembly 5 includes a support plate 53 fixedly mounted on the inner wall of the protective box 2, a cache box 54 fixedly mounted on the support plate 53, a liquid spray pipe 518 fixedly connected to the lower end of the cache box 54, a vibration mechanism installed on the cache box 54, and a transmission component installed on the support plate 53.

[0037] The vibration mechanism includes a liquid supply box 51 fixedly mounted on the inner bottom wall of the protection box 2, and a water pump (not shown in the figure but not marked) is installed on the liquid supply box 51. Fig.10 As can be seen in the figure, the water inlet end of the water pump is fixedly connected to a suction pipe, the water outlet end of the water pump is fixedly connected to a liquid infusion pipe 52, and one end of the liquid infusion pipe 52 is sealed and fixedly installed on the buffer box 54; The buffer box 54 is provided with a limit groove, on which a fixed plate 55 is rotatably mounted, and the fixed plate 55 is sealed and penetrated and fixedly mounted with ring-shaped and uniformly distributed vibration rods 56, and a groove body (drawn but not marked in the figure, from the lower end of the box body 42) is provided. Figure 5As can be seen in the figure, a spring support 59 is slidably mounted on the groove body, and two spring support members 59 are provided. A pressing plate 510 is fixedly mounted between the two spring support members 59. Round rods 57 evenly distributed in a ring shape are fixedly mounted on the lower end of the pressing plate 510. A knocking block 58 is fixedly mounted on the lower end of the round rods 57. A connecting plate 511 is rotatably mounted on the pressing plate 510, and a driving component is installed between the fixed plate 55 and the box body 42.

[0038] The driving component includes a servo motor 2 512 fixedly mounted at the lower end of the box body 42, a transmission rod 513 fixedly mounted on the driving end of the servo motor 2 512, a gear block 515 fixedly mounted on the fixed plate 55, two gear blocks 515 are provided, and an incomplete gear 1 514 matching the two gear blocks 515 is fixedly mounted on the transmission rod 513.

[0039] The transmission component includes a vertical plate fixedly mounted on the support plate 53, a rotating shaft 516 is passed through the vertical plate and rotatably mounted, a cam 517 is fixedly mounted on the rotating shaft 516, a bevel gear 1 is fixedly mounted on the rotating shaft 516, and a bevel gear 2 meshing with the bevel gear 1 is fixedly mounted on the transmission rod 513.

[0040] The liquid supply box 51 stores a pre-input cleaning liquid, which can be an acidic cleaning liquid suitable for removing oxide scale (such as diluted sulfuric acid or hydrofluoric acid), so that the cleaning liquid sprayed from the subsequent liquid spray pipe 518 can dissolve the oxide, i.e., oxide scale, covering the surface of the screw 3.

[0041] When the right spray pipe 44 rapidly quenches and cools the high-temperature screw rod 3 (such as Figure 5 The water pump and the servo motor 2 512 are started. The operation of the water pump can input the cleaning liquid stored in the liquid supply box 51 into the buffer box 54 through the cooperation of the suction tube and the infusion tube 52. The operation of the servo motor 2 512 can drive the pressing plate 510 to move up and down intermittently (such as Fig.11 In the process of intermittent downward movement, the pressing plate 510 drives multiple knocking blocks 58 through multiple round rods 57 to intermittently knock on the corresponding vibration rods 56. The vibration force generated during the knocking of the multiple vibration rods 56 will be transmitted to the cleaning liquid cached in the cache box 54. When the liquid is continuously knocked and vibrated, pressure waves will be generated, causing cavitation in the local low-pressure area of ​​the liquid, thereby forming bubbles in the cleaning liquid.

[0042] When the screw 3 after preliminary quenching and cooling rotates and moves to the lower end of the spray pipe 518, by starting an electric valve 1 (not shown in the figure) on the spray pipe 518, the cleaning liquid cached in the cache box 54 can be sprayed toward the screw 3 from the spray pipe 518, thereby effectively removing the oxide scale on the surface of the screw 3, which can help improve the uniformity of cooling the outer surface of the screw 3 when the subsequent equipment sprays and quenches the screw 3 again. When the cleaning liquid containing a large number of bubbles is sprayed onto the surface of the screw 3, when the bubbles burst, they will release a lot of energy and generate impact force on the surface of the screw 3, which can help improve the effect of removing the oxide scale on the surface of the screw 3 by the cleaning liquid.

[0043] At the same time, the cleaning liquid should be a water-based solution containing an appropriate amount of surfactant and solvent. These solutions can reduce surface tension, make bubbles more easily generated and stabilized, and help enhance the permeability of the cleaning liquid, thereby improving the cleaning liquid's effect on removing oxide scale on the surface of the screw 3.

[0044] At the same time, when the transmission rod 513 cooperates with the cam 517 to strike the multiple vibration rods 56 at a high frequency, causing bubbles to be continuously generated in the cleaning fluid in the cache box 54, the transmission rod 513 and the incomplete gear 1 514 intermittently cooperate with the two tooth blocks 515, and the fixed plate 55 can be driven to drive the multiple vibration rods 56, the round rod 57, the knocking block 58 and the pressing plate 510 to rotate together. During the rotation of the multiple vibration rods 56, tangential flow stress will be generated on the cleaning fluid inside the cache box 54, causing the bubbles already formed in the cleaning fluid to disperse, and the rotating multiple vibration rods 56 can vibrate the cleaning fluid area inside the cache box 54 that was not fully disturbed, further promoting the uniformity of the bubble distribution in the cleaning fluid, thereby helping to improve the uniformity of the bubble distribution in the cleaning fluid sprayed out by the subsequent spray pipe 518, and helping to further improve the cleaning fluid The effect of removing the oxide scale on the surface of the screw 3.

[0045] At the same time, in order to ensure that the multiple knocking blocks 58 vibrate the cleaning liquid through the vibration rod 56 to produce bubbles, the servo motor 2 512 is required to drive the transmission rod 513 to run quickly. If the transmission rod 513 drives the fixed plate 55 to drive the multiple vibration rods 56 to rotate too fast, the multiple vibration rods 56 will violently stir the cleaning liquid, causing the cleaning liquid to rotate at a high speed. The strong shear force generated by the high-speed rotation of the cleaning liquid can easily cause the internal bubbles to break, reducing the number of bubbles in the cleaning liquid, that is, reducing the subsequent cleaning liquid's effect of removing the oxide scale on the surface of the screw 3; Therefore, through the intermittent cooperation between the incomplete gear 514 and the two tooth blocks 515, the rotation speed of the transmission rod 513 driving the fixed plate 55 and the multiple vibration rods 56 can be effectively reduced, ensuring that the rotation of the multiple vibration rods 56 promotes the uniformity of the bubble distribution in the cleaning liquid, and can also effectively reduce the damage of the rotation of the multiple vibration rods 56 to the bubbles in the cleaning liquid.

[0046] At the same time, from Figure 3 It can be seen that a collecting trough is provided at the lower end of the protective box 2, and two isolation plates are installed on the collecting trough. Through the cooperation of the collecting trough and the two isolation plates, the waste water sprayed by the two spray pipes 44 on the screw rod 3 for quenching and cooling can be collected on the left and right sides of the collecting trough, and the waste liquid sprayed by the spray pipe 518 on the surface of the screw rod 3 can be collected in the middle of the collecting trough, so that the staff can recover the waste water and waste liquid separately.

[0047] like Figure 5 , Fig. 9 , Fig.14 As shown, the jet assembly 6 includes a positioning plate 63 fixedly mounted on the lower end of the box body 42, a buffer box 64 fixedly mounted on the positioning plate 63, a jet pipe 65 fixedly connected to the lower end of the buffer box 64, two jet pipes 65 are provided, and an extrusion component is provided in the buffer box 64.

[0048] The extrusion component includes a partition 610 fixedly installed in the cache box 64, a sealing plate 66 is sealed and slidably installed between the cache box 64 and the partition 610, a sealing plate 67 is sealed and slidably installed between the cache box 64 and the partition 610, and the upper end of the sealing plate 67 is fixedly connected to the connecting plate 511, a winding roller 69 is rotatably installed on the partition 610, a guide roller is rotatably installed on the inner wall of the cache box 64, and there are two guide rollers, a steel belt 68 is commonly wound and installed between the two guide rollers and the winding roller 69, and one end of the steel belt 68 is fixedly connected to the sealing plate 66, and the other end of the steel belt 68 is fixedly connected to the sealing plate 2 67, an air tank 61 is fixedly installed on the inner bottom wall of the protective box 2, and an air supply pipe 62 is fixedly connected between the air tank 61 and the cache box 64.

[0049] When the liquid spraying pipe 518 starts to spray the cleaning liquid on the surface of the screw rod 3 to remove the oxide scale on the surface of the screw rod 3, the gas storage tank 61 is started (the gas stored in the gas storage tank 61 is inert, such as nitrogen or argon). At this time, the inert gas stored in the gas storage tank 61 will enter the buffer box 64 along the gas supply pipe 62. When the screw rod 3 moves to the lower end of the right injection pipe 65 (such as Fig. 9 In the direction shown), the electric valve 2 (not shown) on the two jet pipes 65 is started, and the oxide scale remaining on the surface of the screw rod 3 can be blown off through the two jet pipes 65, thereby further improving the effect of removing the oxide scale on the surface of the screw rod 3 and further improving the uniformity of the subsequent equipment in water spray quenching cooling on the surface of the screw rod 3.

[0050] At the same time, the overall weight of the sealing plate 1 66 is set to be greater than that of the sealing plate 2 67, so that when the servo motor 2 512 is running, the pressing plate 510 is driven to move up and down (such as Fig.11 The pressing plate 510 will drive the sealing plate 67 to move up and down through the connecting plate 511 (as shown in the direction of FIG. Fig.14 When sealing plate 2 67 is forced to move downward, the cooperation of winding roller 69, two guide rollers and steel belt 68 will cause the left end of steel belt 68 to pull sealing plate 1 66 upward. When sealing plate 2 67 is forced to move upward, sealing plate 1 66 moves downward under the action of its own gravity, thereby achieving the effect of relative up and down movement of sealing plate 1 66 and sealing plate 2 67.

[0051] When the sealing plate 2 67 moves downward and squeezes the inert gas at its lower end, the ejection speed of the inert gas on the right side of the buffer box 64 can be accelerated (eg Fig.14 In the direction shown), that is, increasing the jet pressure and jet volume of the right jet pipe 65, prompting the right jet pipe 65 to eject a pulse airflow, and the instantaneous impact force generated by the pulse airflow can further improve the effect of the jet pipe 65 on blowing off the residual oxide scale on the surface of the screw rod 3, and further improve the gas cleaning effect on the oxide scale on the surface of the screw rod 3.

[0052] When the sealing plate 66 moves downward, the inert gas at its lower end is squeezed (such as Fig.14 The left end jet pipe 65 can also be prompted to eject pulsed airflow, and the left and right side jet pipes 65 intermittently and in coordination with each other eject pulsed airflow to the surface of the screw rod 3 (such as Fig. 9 The direction shown in the figure) can further ensure the effect of the two air injection pipes 65 on removing the oxide scale on the surface of the screw rod 3.

[0053] like Fig.13 , Fig.15 - Fig.19 As shown, the positioning assembly 7 includes a positioning frame 71 fixedly mounted on the support frame 1, and two positioning frames 71 are provided. The two positioning frames 71 are rotatably mounted with threaded rods 78 evenly distributed in an annular shape, and the threaded rods 78 are fixedly mounted with parallel axis gears 79. The threaded rods 78 are threadedly mounted with sliding members 710, and the sliding members 710 are rotatably mounted with limiting rollers 711. Both positioning frames 71 are provided with an annular groove 712, on which a gear ring 77 is rotatably mounted, and both gear rings 77 are meshed with corresponding parallel axis gears 79, and both gear rings 77 are fixedly mounted with a turntable 76, and a striking component is installed between the two positioning frames 71 and the rotating shaft 516.

[0054] The knocking component includes an incomplete gear 2 72 fixedly mounted on the rotating shaft 516, a rack push rod 1 73 is sealed and slidably mounted on the protection box 2, a rack push rod 2 74 is sealed and slidably mounted on the protection box 2, and the rack push rod 1 73 and the rack push rod 2 74 are both matched with the incomplete gear 2 72, a spring knocking plate 75 is fixedly mounted on the protection box 2, two spring knocking plates 75 are provided, and the left spring knocking plate 75 is fixedly connected to the rack push rod 1 73, and the right spring knocking plate 75 is fixedly connected to the rack push rod 2 74 (the left and right here refer to Fig.15 , Fig.15 The position of the rack push rod 2 74 in the figure is the left side, and the position of the positioning frame 71 in the figure is the right side).

[0055] Before the equipment starts to quench the screw 3, the spacing between the corresponding multiple limiting rollers 711 can be adjusted according to the diameter of the screw 3. If the spacing between the corresponding multiple limiting rollers 711 needs to be increased, the corresponding gear ring 77 can be driven to rotate by rotating the turntable 76. During the rotation of the gear ring 77, the corresponding multiple limiting rollers 711 can be driven away from each other by cooperating with the corresponding multiple parallel shaft gears 79, multiple threaded rods 78 and multiple sliding parts 710. Conversely, by reversing the turntable 76, the corresponding multiple limiting rollers 711 can be driven to move closer to each other.

[0056] When the screw rod 3 is subjected to force and continuously moves to the left (such as Fig.15 In the direction shown), the movement of the screw rod 3 can be limited by the cooperation of the corresponding multiple limiting rollers 711 on the left and right sides, which helps to improve the stability of the movement of the screw rod 3 during the displacement of the screw rod 3 by the pushing device 9, and can also improve the heating, cooling and cleaning effects of the device on the screw rod 3 to a certain extent.

[0057] At the same time, when the transmission rod 513 is driven by the force to drive the rotating shaft 516 to rotate counterclockwise (such as Fig.15The rotating shaft 516 drives the incomplete gear 2 72 to intermittently mesh with the rack push rod 1 73 and the rack push rod 2 74. When the incomplete gear 2 72 rotates counterclockwise to mesh with the rack push rod 1 73 and push the rack push rod 1 73 to move to the left, the rack push rod 1 73 drives the corresponding spring knocking plate 75 to quickly knock the corresponding positioning frame 71, and the vibration force generated by the knocking of the left positioning frame 71 is transmitted to the plurality of limit rollers 71 through the corresponding plurality of threaded rods 78. The cooperation is transferred to the screw rod 3, which causes tiny elastic waves to be generated inside the screw rod 3, and these elastic waves help to transfer the heat inside the screw rod 3 to the outer layer of the screw rod 3. For example, knocking and vibrating the screw rod 3 can break the thermal boundary layer formed by the temperature gradient inside the screw rod 3, so that the heat can be transferred from the inside to the surface faster, thereby reducing the temperature difference between the surface and the inside. In this way, the uniformity of the quenching and cooling of the inner and outer layers of the screw rod 3 by the equipment can be further improved, which helps to further improve the quenching and cooling effect of the equipment on the screw rod 3.

[0058] At the same time, when the incomplete gear 2 72 is forced to rotate counterclockwise away from the rack push rod 1 73, the rack push rod 1 73 can be driven to move quickly to the right and reset (such as Fig.15 When the incomplete gear 2 72 is forced to rotate counterclockwise and gradually approach the rack push rod 2 74, the rack push rod 2 74 cooperates with the corresponding spring knocking plate 75, and the knocking vibration effect on the screw rod 3 can be achieved by knocking the right positioning frame 71.

[0059] Instructions for use: Before the screw rod 3 needs to be quenched, water is first supplied to the interior of the box 42 through the existing water supply equipment, and the exhaust fan 48 and the servo motor 45 are started. During the operation of the exhaust fan 48, the gas in the box 42 and the temperature control cover 410 can be extracted by cooperating with the oxygen absorbing component, so as to promote the escape of oxygen collected in the temperature control cover 410, thereby achieving the effect of deoxygenating the water body and improving the effect of subsequent equipment on the quenching and cooling of the high-temperature screw rod 3. The operation of the servo motor 45 can accelerate the escape speed of oxygen in the water body. At the same time, the drainage volume of the two drainage ports 414 can be adjusted according to needs through the cooperation of the servo motor 45 and the adjustment component (such as Figure 6 As shown, the drainage volume of the right drainage port 414 is greater than the drainage volume of the left drainage port 414) When the screw rod 3 is quenched, the drive system 8 and the push device 9 cooperate to drive the screw rod 3 to rotate and move to the left (such as Figure 1 When the heating device 12 is running to heat the screw rod 3 to a high temperature state, and the screw rod 3 moves to the lower end of the left spray pipe 44 (as shown in the direction of FIG. Figure 5In the direction shown), by opening the valves on the two conduits 43, the screw rod 3 can be repeatedly quenched and cooled through the cooperation of the two spray pipes 44, and by reducing the water spraying amount of the right spray pipe 44, the temperature difference between the inner and outer layers of the screw rod 3 during the quenching and cooling process of the screw rod 3 by the equipment can be effectively reduced, which helps to improve the uniformity of the cooling of the inner and outer layers of the screw rod 3 by the equipment.

[0060] At the same time, when the left spray pipe 44 rapidly cools the screw rod 3 (such as Figure 5 In the direction shown), start the servo motor 2 512. Through the cooperation of the servo motor 2 512 and the vibration mechanism, bubbles can be continuously generated in the cleaning liquid inside the cache box 54. When the screw 3 moves to the lower end of the spray pipe 518, the cleaning liquid with a large number of bubbles is sprayed out through the spray pipe 518, which can effectively remove the oxide scale on the surface of the screw 3. This can effectively improve the uniformity of the subsequent overall quenching cooling of the outer surface of the screw 3 by the equipment (the right spray pipe 44). At the same time, through the cooperation of the vibration mechanism and the jet assembly 6, the two jet pipes 65 can intermittently spray pulse airflow to further remove the oxide scale remaining on the surface of the screw 3.

[0061] Furthermore, the positioning component 7 can be used to limit the position of the processed screw rods 3 of different sizes according to the size of the screw rod 3, thereby effectively improving the effect of the equipment on the quenching processing of the screw rod 3. At the same time, by knocking the parts, the heat of the inner layer of the screw rod 3 can be accelerated to transfer to the outside during the quenching and cooling process of the screw rod 3 by the equipment, which helps to further improve the uniformity of the equipment's quenching and cooling of the inside and outside of the screw rod 3.

[0062] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
