It includes a housing, with a water tank fixedly installed on the upper surface of the housing. Water cooling mechanisms for cooling the bearing steel tube blanks are symmetrically installed on both sides of the water tank.

Description

Technical Field

[0001] This utility model belongs to the technical field of bearing steel tube blank processing equipment, and in particular relates to a controlled cooling device after deformation of bearing steel tube blank. Background Technology

[0002] Bearing steel tubes are mainly used to manufacture rolling elements and bearing rings. After the bearing steel tube billet is hot-rolled and pierced, it needs to be cooled by a controlled cooling device to suppress the precipitation of network carbides, obtain the required structure and properties, and reduce the possibility of deformation and cracking of the bearing steel tube.

[0003] For example, Chinese patent CN207887635U discloses a controlled cooling device for hot-rolled piercing of bearing steel tube blanks. The device includes a housing with legs fixedly connected to both sides of the bottom. Through slots are provided on both sides of the housing, and a conveyor belt is installed inside the housing, with both ends extending to the outside of the housing. This invention achieves excellent controlled cooling by coordinating the housing, legs, through slots, conveyor belt, temperature sensor, water tank, water inlet pipe, temperature setting device, protective box, processor, bracket, water pump, suction pipe, connecting pipe, outlet pipe, spray head, buckle, heat dissipation holes, dust baffle, and anti-slip pad. This allows for accurate temperature control of the bearing steel tube blank during use, preventing damage and extending its service life, thus improving the practicality of the controlled cooling device.

[0004] This patented device has some drawbacks in its use. For example, while it cools the bearing steel tube by spraying water droplets from a nozzle, some cooling water flows to the bottom of the chamber due to gravity after cooling. Since this water is in contact with the hot steel, its temperature rises. When a large amount of hot water remains at the bottom of the chamber, the temperature inside remains high for an extended period, reducing the overall cooling effect and efficiency of the device. Furthermore, the device cannot effectively treat or recycle the remaining hot water inside the chamber. Therefore, we propose a cooling control device for bearing steel tube blanks after deformation. Utility Model Content

[0005] The purpose of this invention is to provide a controlled cooling device for bearing steel tube blanks after deformation, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a controlled cooling device for bearing steel tube blanks after deformation, comprising:

One end of a conveying roller penetrates the inner wall of the housing and extends into the drive box, where it is coaxially connected to the corresponding worm wheel. The other end of the conveying roller is coaxially connected to a bearing seat, which is fixedly installed on the inner wall of the housing.

[0015] In this technical solution, a heat insulation cover fixed to the outer wall of the drive box is provided around the motor, and the heat insulation cover completely blocks the side of the motor facing the feed port of the box.

[0016] In this technical solution, the air-cooling mechanism includes:

[0017] An air inlet is located directly above the discharge port of the housing. A fan is fixedly installed inside the air inlet by bolts. A dustproof net that engages with the air inlet is installed on the outside of the fan. A protective mesh plate is fixedly installed at the outer opening of the air inlet by bolts.

[0020] The beneficial effects of this utility model are:

The bearing steel tube blank deformation cooling device, by setting up an air-cooling mechanism, uses the air generated by the fan to quickly dissipate heat from the upper part of the inner cavity of the box, avoiding the continuous heat accumulation caused by high temperature water vapor inside the box, thereby ensuring that the inner cavity of the box is always in a relatively low constant temperature space, avoiding the adverse effect of the temperature inside the box continuously rising due to the large accumulation of hot steam, which would reduce the cooling efficiency of the bearing steel tube blank.

[0022] 2. The controlled cooling device after the bearing steel tube blank is deformed, by setting up a water recovery component, and by using the cooperation of water pump and pipe, the water filtered in the lower part of the inner cavity of the tank can be transported back to the inner cavity of the water tank, which improves the circulation effect and utilization rate of water resources in the water tank, effectively saves water resources and reduces production costs.

[0035] Example 1:

[0036] Please see Figure 1 - Figure 5 As shown, this embodiment provides a controlled cooling device for bearing steel tube blanks after deformation, including:

[0037] Box 1, with a water tank 2 fixedly installed on the upper surface of box 1. Water cooling mechanisms for cooling bearing steel tube blanks are symmetrically installed on both sides of water tank 2. The water cooling mechanism consists of a booster pump 3, a water supply pipe 4, a diversion pipe 5, and multiple high-pressure atomizing nozzles 6. A feed inlet is opened on the right side of box 1, and a discharge outlet is opened on the left side of box 1. Multiple conveying rollers 7 with linear and equal spacing are rotatably installed in the inner cavity of box 1.

[0038] The drive mechanism is located on the front side wall of the housing 1 and is used to control the rotation of multiple bearing seats 8;

[0039] The air-cooling mechanism is located on the side wall of the box 1 near the upper part of the discharge port and is used to quickly cool the inner cavity of the box 1.

[0040] A water recycling assembly is installed on the tank 1 and the water tank 2, and is used to recycle water from the bottom of the inner cavity of the tank 1 into the water tank 2.

[0041] In this embodiment, the booster pump 3 is fixedly installed on the upper surface of the housing 1, the water inlet end of the housing 1 is connected to the inner cavity of the water tank 2, the water supply pipe 4 is fixedly installed on the water outlet end of the booster pump 3, and the other end of the water supply pipe 4 is located in the inner cavity of the housing 1. The diversion pipe 5 is fixedly installed on one end of the water supply pipe 4 located in the inner cavity of the housing 1. Multiple high-pressure atomizing nozzles 6 are linearly and equally spaced, and the multiple high-pressure atomizing nozzles 6 are fixed to the diversion pipe 5.

[0042] In this embodiment, the high-pressure atomizing nozzle 6 is inclined, and the nozzle of the high-pressure atomizing nozzle 6 faces inward toward the side of the bearing steel tube blank.

[0043] The bearing steel tube blank enters the inner cavity of the box 1 from the feed port on the right side of the box 1 and is discharged from the inner cavity of the box 1 from the discharge port on the left side. During this process, the bearing steel tube blank is fully cooled in the inner cavity of the box 1 by the action of two sets of water cooling mechanisms, thereby reducing the possibility of deformation and cracking of the bearing steel tube blank due to high temperature after heat treatment.

[0044] During this process, the drive mechanism is activated, which drives multiple conveying rollers 7 to rotate counterclockwise, thereby causing the bearing steel tube blank to slide from the feed port on the right side into the inner cavity of the box 1 towards the discharge port on the left side. Under the action of the water cooling mechanism, it achieves a two-stage full cooling and temperature reduction, improving the continuity and efficiency of the production process. When the water cooling mechanism is working, two booster pumps 3 are activated, which pressurize the cooling water in the water tank 2 and deliver it to the water supply pipe 4. Then, it is delivered to the distribution pipe 5 through the water supply pipe 4, and high-pressure and mist-like small water droplets are sprayed out through multiple high-pressure atomizing nozzles 6. The small water droplets come into contact with the surface of the bearing steel tube blank, thereby rapidly cooling the bearing steel tube blank.

[0045] When water comes into contact with the high-temperature bearing steel tube blank, it generates a large amount of steam and heat, which rises to the upper part of the inner cavity of the housing 1. At this time, the air-cooling mechanism is activated, drawing in cool air from the outside through the air inlet 15 and discharging the high-temperature gas inside the housing 1 from the heat dissipation hole 19 on the right side. This ensures that the inner cavity of the housing 1 is always in a relatively low constant temperature space, avoiding the adverse effect of the temperature inside the housing 1 continuously rising due to the accumulation of a large amount of hot steam, which would reduce the cooling efficiency of the bearing steel tube blank. In addition, some cooling water slides down from the bearing steel tube blank under the action of gravity and falls to the bottom of the inner cavity of the housing 1 after being filtered by the filter screen 25. At this time, the water recovery component is activated, which can recover the cooling water at the bottom of the housing 1 back into the water tank 2, thereby reducing water waste and improving water utilization.

[0046] It is worth noting that the bottom surface of the inner cavity of the box 1 is inclined towards the bottom center, and one end of the through pipe 21 is located at the bottom center of the inner cavity of the box 1, thereby ensuring that the water at the bottom of the inner cavity of the box 1 can be fully recycled by the through pipe 21. In addition, since the temperature on the side of the inlet of the box 1 is not cooled by the water cooling mechanism, the ambient temperature is relatively high. Therefore, the air cooling mechanism is located above the left outlet of the box 1 to improve the heat dissipation efficiency. Furthermore, it is worth noting that in order to reduce the impact of the high temperature environment on the motor 13, the motor 13 in the drive mechanism in this application can be located on the side close to the outlet of the box 1. The attached drawings in the specification are for reference only and do not represent the actual optimal situation.

[0047] Example 2:

[0048] This embodiment provides a controlled cooling device for bearing steel tube blanks after deformation. In addition to the technical solutions of the above embodiments, it also has the following technical features, including a driving mechanism comprising:

[0049] A drive box 9 is fixedly installed on the front side wall of the housing 1. A transmission rod 10 is rotatably installed in the inner cavity of the drive box 9. Multiple worm gears 11 with linear and equal spacing are coaxially connected to the transmission rod 10. Worm wheels 12 are meshed on the periphery of the worm gears 11 and are rotatably installed in the inner cavity of the drive box 9. One end of the conveying roller 7 passes through the inner wall of the housing 1 and extends into the drive box 9 and is coaxially connected to the corresponding worm wheel 12. The other end of the conveying roller 7 is coaxially connected to a bearing seat 8, and the bearing seat 8 is fixedly installed on the inner wall of the housing 1. A motor 13 is fixedly installed on the outer wall of the drive box 9, and the output shaft of the motor 13 is coaxially connected to the transmission rod 10.

[0050] When the drive assembly is working, the motor 13 is started, the output shaft of the motor 13 rotates and drives the transmission rod 10 to rotate. At this time, multiple worm gears 11 located on the transmission rod 10 rotate synchronously and drive the corresponding worm wheels 12 to rotate. The worm wheels 12 then drive the corresponding conveying rollers 7 to rotate, thereby realizing the conveying of the bearing steel tube blank.

[0051] By setting up a drive assembly, multiple conveying rollers 7 can rotate within the cavity of the housing 1, thereby facilitating the conveying of the bearing steel tube blank.

[0052] Example 3:

[0053] This embodiment provides a controlled cooling device for bearing steel tube blanks after deformation. In addition to the technical solutions of the above embodiments, it also has the following technical features: a heat insulation cover 14 fixed to the outer wall of the drive box 9 is provided on the periphery of the motor 13. The heat insulation cover 14 completely blocks the side of the motor 13 facing the feed port of the box 1.

[0054] The heat insulation cover 14 is made of heat insulation material, which effectively prevents the high temperature gas near the box 1 from causing adverse effects on the motor 13. The outer side of the heat insulation cover 14 is open to facilitate heat dissipation of the motor 13.

[0055] By installing a heat insulation cover 14 around the motor 13, the high-temperature gas near the housing 1 can be effectively prevented from having an adverse effect on the motor 13.

[0056] Example 4:

[0057] This embodiment provides a controlled cooling device for bearing steel tube blanks after deformation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the air-cooling mechanism includes:

[0058] An air inlet 15 is located directly above the discharge port of the housing 1. A fan 16 is fixedly installed inside the air inlet 15 by bolts. A dustproof net 17 that engages with the air inlet 15 is provided on the outside of the fan 16. A protective mesh plate 18 is fixedly installed at the outer opening of the air inlet 15 by bolts. Multiple evenly distributed heat dissipation holes 19 are provided on one side of the feed port of the housing 1.

[0059] When the air-cooling mechanism is working, the fan 16 is started. At this time, the fan 16 works and generates negative pressure, thereby drawing air from the outside of the housing 1 into the inner cavity of the housing 1 through the air inlet 15. The hot air accumulated in the inner cavity of the housing 1 is then discharged to the outside through the heat dissipation hole 19. During this process, dust in the outside air can be filtered, adsorbed and blocked by the dustproof net 17. When it is necessary to clean and replace the dustproof net 17, simply unscrew the fixing bolts of the protective net plate 18 and then remove the dustproof net 17 from the inner cavity of the air inlet 15. The dustproof net 17 is engaged with the air inlet 15 through a snap-fit ​​design. This is prior art and should be well known to those skilled in the art. This application will not elaborate further on it.

[0060] By setting up a wind-cooling mechanism, the air generated by the fan 16 during operation is used to quickly dissipate heat from the upper part of the inner cavity of the box 1, avoiding the continuous heat accumulation caused by high-temperature water vapor inside the box 1. This ensures that the inner cavity of the box 1 is always in a relatively low constant temperature space, preventing the temperature inside the box 1 from continuously rising due to the large accumulation of hot steam, which would have a negative impact on the cooling efficiency of the bearing steel tube blank. The dustproof net 17 provides protection for the fan 16, and the protective mesh plate 18 provides a certain degree of protection for both the fan 16 and the dustproof net 17.

[0061] Example 5:

[0062] This embodiment provides a controlled cooling device for bearing steel tube blanks after deformation. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the water recovery component includes:

[0063] A water pump 20 is fixedly installed in the inner cavity of the water tank 2. A through pipe 21 is provided on the rear side of the tank body 1. One end of the through pipe 21 is fixed to the bottom of the inner cavity of the tank body 1, and the other end of the through pipe 21 passes through the outer wall of the water tank 2 and extends into the water tank 2 to be fixed to the output end of the water pump 20. A water inlet 22 is provided on the upper surface of the water tank 2. Support bars 23 are symmetrically fixed in the inner cavity of the tank body 1 and below multiple conveying rollers 7. An insertion hole 24 is provided below the feed inlet of the tank body 1. Filter screens 25 are slidably installed on the upper surfaces of the two support bars 23 and are inserted into the insertion hole 24.

[0064] When it is necessary to recycle the cooling water in the lower part of the inner cavity of the housing 1, the water pump 20 is started. At this time, the water in the lower part of the inner cavity of the housing 1 can be transported to the inner cavity of the water tank 2 through the pipe 21. It is worth noting that, due to the presence of the filter screen 25, the water generated by the upper water cooling mechanism during the cooling of the bearing steel tube blank can be effectively filtered, avoiding the presence of a large number of impurities in the water in the lower part of the inner cavity of the housing 1, which would affect the normal operation of the water cooling mechanism. When it is necessary to clean the filter screen 25, it is only necessary to pull the filter screen 25 out of the insertion hole 24.

[0065] By setting up a water recycling component, and using the cooperation of water pump 20 and pipe 21, the filtered water in the lower part of the inner cavity of tank 1 can be transported back to the inner cavity of water tank 2, which improves the circulation effect and utilization rate of water resources in water tank 2, effectively saves water resources and reduces production costs.

[0066] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
