Description
Technical Field
[0001] This utility model relates to the field of bearing processing and application technology, and in particular to a rapid cooling device for bearing rings after heat treatment. Background Technology
[0002] Heat treatment is a crucial step in the production of bearing rings, and cooling is an indispensable part of the heat treatment process. The cooling rate has a significant impact on the microstructure and properties of the bearing rings; a suitable cooling rate ensures that the rings achieve good overall properties such as hardness, strength, and toughness.
[0003] However, existing cooling devices have some shortcomings. On the one hand, traditional cooling methods have a slow cooling speed, which cannot meet the requirements of some bearing ring heat treatment processes with high cooling speed requirements, resulting in low production efficiency and potentially affecting product quality. On the other hand, during the cooling process, the distribution of coolant is uneven, causing inconsistent cooling of different parts of the bearing ring, which can easily lead to defects such as deformation. In addition, the existing devices are not perfect in terms of coolant recovery and reuse, resulting in waste of resources and increased costs. Therefore, this utility model proposes a rapid cooling device for bearing rings after heat treatment. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a rapid cooling device for bearing rings after heat treatment, so as to solve the problems of slow cooling speed, uneven cooling and imperfect coolant recovery mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention provides a rapid cooling device for bearing rings after heat treatment, including a cooling box, wherein an air supply system is installed on the outer wall of the cooling box to perform air cooling operation on the bearing rings placed inside.
[0006] A spray cooling assembly is fixedly connected to the inner top of the cooling box to perform water cooling on the placed bearing rings.
[0007] The cooling box is internally bolted with a rotating mechanism to rotate the inserted bearing rings.
[0008] The present invention is further configured such that: multiple anti-slip pads are equidistantly distributed on the bottom circumference of the cooling box.
[0009] The above technical solution makes it easy to fix the entire cooling box in place using anti-slip pads, preventing it from tipping over or shaking during use.
[0010] The present invention is further configured such that: a partition is bolted to the interior of the cooling box near the middle position, and the interior of the cooling box is divided into a coolant collection tank and a cooling chamber by the partition, and the coolant collection tank is located below the partition and the cooling chamber is located above the partition. A guide plate is provided at the bottom of the partition, and the guide plate is arranged in the shape of a conical funnel.
[0011] The above technical solution prevents the inserted bearing rings from falling out by using a partition, and the guide plate collects the sprayed coolant to avoid waste. At the same time, the cooling chamber allows the inserted bearing rings to move freely.
[0012] The present invention is further configured such that: the outer wall of the cooling box is provided with a discharge port and a discharge port at the location of the cooling cavity, and the discharge port and discharge port correspond to the installation position of the rotating mechanism and are higher than the installation position of the partition.
[0013] The above technical solution facilitates the insertion and removal of bearing rings that require cooling, and the two openings can increase the air cooling effect.
[0014] The present invention is further configured such that: the air supply system includes two air supply fans installed on the outer wall of the coolant collection tank, and the two air supply fans are higher than the coolant inside the coolant collection tank; and two sets of exhaust fans are symmetrically fixedly connected to the outer wall of the cooling chamber.
[0015] The above technical solution uses a blower fan to introduce external air into the coolant collection tank. After being cooled by the coolant, the air inside is exhausted by an exhaust fan. The cooled air is then blown through a baffle to multiple bearing rings, and in conjunction with the cooling of the external air, the cooling process of the bearing rings is achieved.
[0016] The present invention is further configured such that: the spray cooling assembly includes a pump body bolted to the outer wall of the cooling tank; the bottom input end of the pump body is connected to an inlet pipe, which is connected to the interior of the coolant collection tank; the output end of the pump body is connected to a delivery pipe, which is connected to an annular pipe; and multiple nozzles are fixedly connected to the bottom of the annular pipe.
[0017] The above technical solution utilizes a pump body to extract coolant from the coolant collection tank through the inlet pipe, then transmits it through the delivery pipe to the inside of the annular pipe, and finally sprays the coolant onto the outside of multiple bearing rings through multiple nozzles, achieving comprehensive cooling of the bearing rings.
[0018] The present invention is further configured such that: the rotating mechanism includes a motor bolted to the center of the top of the cooling box, the output shaft of the motor is connected to a rotating shaft, a support frame is sleeved on the outer wall of the rotating shaft, and multiple positioning columns are fixedly connected to the end face of the support frame.
[0019] With the above technical solution, the motor is started, and its output shaft drives the rotating shaft on the end face to rotate, thereby driving multiple receiving frames to rotate, causing the bearing rings sleeved on the positioning column to rotate and move away from the discharge port, thus making it easier to remove from the discharge port.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. The bearing ring rapid cooling device proposed in this utility model has a combination of spray water cooling and air cooling structure, which enables the bearing ring to be placed in a rapid cooling operation, thereby improving the cooling efficiency of the bearing ring.
[0022] 2. The bearing ring rapid cooling device proposed in this utility model has a rotating mechanism inside the cooling device, which can rotate the inserted bearing ring, thus separating the operation of inserting and removing the bearing ring, thereby improving the continuous operation efficiency of bearing ring.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0030] like Figures 1-3 As shown, a rapid cooling device for bearing rings after heat treatment includes a cooling box 1. Multiple anti-slip pads 11 are evenly distributed around the bottom circumference of the cooling box 1 to secure its position and prevent tipping or shaking during use. A partition 13 is bolted to the interior of the cooling box 1 near the center, dividing the interior into a coolant collection tank 12 and a cooling chamber 14. The coolant collection tank 12 is located below the partition 13, and the cooling chamber 14 is located above the partition 13. A guide plate 15 is provided at the bottom of the partition 13. The flow plate 15 is set in the shape of a conical funnel. The baffle 13 can prevent the inserted bearing rings from falling out. The flow guide plate 15 can collect the sprayed coolant to avoid waste. At the same time, the cooling chamber 14 can facilitate the movement of the inserted bearing rings. The outer wall of the cooling box 1 has a discharge port 16 and a discharge port 17 at the location of the cooling chamber 14. The discharge port 16 and the discharge port 17 correspond to the installation position of the rotating mechanism 4 and are higher than the installation position of the baffle 13, which facilitates the insertion and removal of the bearing rings that need to be cooled. The two openings can also increase the air cooling effect.
[0031] like Figure 1 and Figure 2 As shown, an air supply system 2 is installed on the outer wall of the cooling box 1 to perform air cooling operation on the placed bearing rings. The air supply system 2 includes two air supply fans 21 installed on the outer wall of the coolant collection tank 12, and the two air supply fans 21 are higher than the coolant inside the coolant collection tank 12. Two sets of exhaust fans 22 are symmetrically fixedly connected to the outer wall of the cooling chamber 14. The air supply fans 21 introduce external air into the coolant collection tank 12. After being cooled by the coolant, the exhaust fans 22 exhaust the internal air, so that the cooled air is blown to multiple bearing rings through the partition 13, and in conjunction with the cooling of the external air, the cooling process of the bearing rings is achieved.
[0032] like Figure 3 and Figure 4 As shown, a spray cooling assembly 3 is fixedly connected to the top of the inner side of the cooling tank 1 for water cooling of the placed bearing rings. The spray cooling assembly 3 includes a pump body 31 bolted to the outer wall of the cooling tank 1. The bottom input end of the pump body 31 is connected to an inlet pipe 32, which is connected to the inside of the coolant collection tank 12. The output end of the pump body 31 is connected to a delivery pipe 33, which is connected to an annular pipe 34. Multiple nozzles 35 are fixedly connected to the bottom of the annular pipe 34. The pump body 31 can draw coolant from the inside of the coolant collection tank 12 through the inlet pipe 32, and then transfer it to the inside of the annular pipe 34 through the delivery pipe 33. Finally, the coolant is sprayed onto the outside of multiple bearing rings through the multiple nozzles 35 to achieve comprehensive cooling of the bearing rings.
[0033] like Figure 1 and Figure 5 As shown, the cooling box 1 is bolted to a rotating mechanism 4 to rotate the inserted bearing rings. The rotating mechanism 4 includes a motor 41 bolted to the center of the top of the cooling box 1. The output shaft of the motor 41 is connected to a rotating shaft 42. A receiving frame 43 is sleeved on the outer wall of the rotating shaft 42. Multiple positioning posts 44 are fixedly connected to the end face of the receiving frame 43. When the motor 41 is started, its output shaft drives the rotating shaft 42 on the end face to rotate, thereby driving the multiple receiving frames 43 to rotate, causing the bearing rings sleeved on the positioning posts 44 to rotate and move away from the discharge port 16, so that they can be easily removed from the discharge port 17.
[0034] In use, the bearing rings to be cooled are first placed into the positioning pins 44 on the receiving frame 43. Then, the motor 41 is started, and its output shaft drives the rotating shaft 42 on the end face to rotate, thereby driving multiple receiving frames 43 to rotate, causing the bearing rings fitted on the positioning pins 44 to rotate. At the same time, the pump body 31 can draw coolant from the coolant collection tank 12 through the inlet pipe 32, and then transfer it through the delivery pipe 33 to the annular pipe 34. Finally, it is discharged through multiple spray nozzles. The head 35 sprays coolant onto the outside of multiple bearing rings to achieve comprehensive cooling of the bearing rings. The sprayed coolant then enters the coolant collection tank 12 from the guide plate 15 for a second spraying operation. The exhaust fan 22 exhausts the internal air, allowing the cooled air to be blown onto the multiple bearing rings through the partition 13. This, combined with the cooling of the external air at the discharge port 16 and outlet 17, achieves the cooling process of the bearing rings. Finally, the bearing rings are removed from the outlet 17.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
