Description

Technical Field

[0001] The present invention relates to the technical field of workpiece heat treatment, and specifically relates to a uniform rapid cooling type heat treatment cooling table. Background Technique

[0002] Metal heat treatment is a process of heating metal workpieces in a certain medium to an appropriate temperature, maintaining for a certain time at this temperature, and then cooling at different speeds. By changing the microstructure on the surface or inside of the metal material, its properties are controlled.

[0003] Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but endows or improves the service performance of the workpiece by changing the microstructure inside the workpiece or the chemical composition on the surface of the workpiece. Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye.

[0004] When the existing rapid cooling type heat treatment cooling table cools the workpiece, during the process of the operator placing the high-temperature workpiece on the cooling table, the high-temperature workpiece is extremely vulnerable to damage by external forces and deforms. Moreover, when the existing rapid cooling type heat treatment cooling table cools the workpiece, if there is a certain temperature difference due to uneven heat dissipation during the cooling process of the workpiece, it will not only cause certain damage to the workpiece and make it deform, but also reduce the cooling effect of the workpiece. Therefore, it is very necessary to design a uniform rapid cooling type heat treatment cooling table that reduces the damage to the workpiece and improves the cooling effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a uniform rapid cooling type heat treatment cooling table to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A uniform rapid cooling type heat treatment cooling table, including a fixing mechanism and an air cooling mechanism. The fixing mechanism is used for placing the workpiece to be cooled, and the air cooling mechanism is located at the bottom of the fixing mechanism and is used for outputting air to cool the workpiece to be cooled. At the same time, the fixing mechanism is used to provide an adjustable moving channel for the air output by the air cooling mechanism. When the air cooling mechanism cools the workpiece to be cooled, the cooling air volume at the workpiece to be cooled is adjusted through the control of the operator.

[0007] According to the above technical solution, the fixing mechanism includes a cooling chamber. One end of the outer side of the cooling chamber is connected to a transmission shaft by a bearing. A wind deflector is drivingly connected to the outer surface of the transmission shaft. A handle is fixedly installed at the end of the wind deflector. An air inlet plate is arranged at the bottom of the cooling chamber. A number of air inlet holes penetrate through the inside of the air inlet plate. When this cooling table is in use, the transmission shaft is used to drive the wind deflector to rotate horizontally through the handle. The air inlet plate is used to place a tray. The tray is used to place workpieces. The number of air inlet holes is used to provide a path for the air output by the air cooling mechanism to enter the cooling chamber.

[0008] According to the above technical solution, the air cooling mechanism includes an air delivery channel. A number of fans are installed at one end of the side of the air delivery channel. The output ends of the number of fans are all inside the air delivery channel. The top of the air delivery channel is connected to the bottom of the cooling chamber through the air inlet plate. When this cooling table is in use, the fans are used to deliver cooling air into the air delivery channel. After the cooling air enters the air delivery channel, it will enter the inside of the cooling chamber through a number of air inlet holes inside the air inlet plate and move outward through the top of the cooling chamber. During this process, the cooling air moves upward from the top of the air inlet holes and then moves upward through a number of pores of the tray to cool the workpieces placed on the top of the tray.

[0009] According to the above technical solution, an output cylinder is provided at the top of one side of the air delivery channel. An output connecting rod is drivingly connected to the top of the output cylinder. A fixed connecting rod is fixedly installed at the end of the output connecting rod. A fixed column is provided at the end of the fixed connecting rod. A cover plate is fixedly installed at the end of the fixed column. A limiting plate is fixedly installed at the top of the cooling chamber. When this cooling table is in use, the output cylinder is used to drive the output connecting rod to move in the vertical direction and drive the fixed column at the end of the fixed connecting rod to move in the vertical direction through the output connecting rod, thereby driving the cover plate to move in the vertical direction. When the cover plate moves to the bottom of the limiting plate, the top of the cooling chamber is a closed structure.

[0010] According to the above technical solution, a high-pressure valve is provided at the end of the air delivery channel. The exhaust end of the high-pressure valve is connected to an exhaust pipe through a pipeline. When this cooling table is in use, the high-pressure valve is used to discharge the gas inside the air delivery channel through the exhaust pipe.

[0011] According to the above technical solution, the limiting plate is in a funnel-shaped structure. When this cooling table is in use, the top of the funnel-shaped limiting plate is higher than its bottom. Therefore, when the cover plate moves to the bottom of the limiting plate, it will make the top of the cooling chamber form a closed structure. When the cover plate moves to the top of the limiting plate, the cooling air inside the cooling chamber can move outward through the gap between the limiting plate and the cover plate.

[0012] According to the above technical solution, the cover plate is slidably connected to the inner wall of the cooling chamber.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the present invention is in use, cooling air is input into the cooling bin through a plurality of groups of air inlet holes inside the air inlet plate and a plurality of gaps inside the tray, so that the cooling air can evenly cool the workpiece on the top of the tray during the flowing process, avoiding deformation of the workpiece due to excessive temperature difference during cooling, and thus improving the cooling quality of the workpiece. When the operator needs to rapidly cool the workpiece, the circulating heat dissipation method in which the cooling air flows from the bottom to the top of the cooling bin cannot meet the heat dissipation conditions required by the workpiece. At this time, the operator drives the cover plate to move to the bottom of the limiting plate through the output cylinder, and continues to adjust the height of the cover plate according to the required cooling rate until the cover plate moves to a certain distance above the workpiece. At this time, the cooling air flowing into the cooling bin through the air inlet plate cannot move to the outside of the cooling bin through the cover plate, and the cooling air will flow into the air delivery channel through the air inlet plate inside the cooling bin, and circulate at a high speed inside the cooling bin and the air delivery channel to rapidly cool the workpiece, significantly improving the corresponding cooling performance.

Detailed Embodiments

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1-5 The present invention provides a technical solution: a uniform rapid cooling heat treatment cooling table, comprising a fixing mechanism and an air cooling mechanism, wherein the fixing mechanism is used to place a workpiece to be cooled, the air cooling mechanism is located at the bottom of the fixing mechanism, and is used to output air to cool the workpiece to be cooled, and at the same time, the fixing mechanism is used to provide an adjustable moving channel for the air output by the air cooling mechanism, and when the air cooling mechanism cools the workpiece to be cooled, the cooling wind force at the workpiece to be cooled is adjusted by the control of the operator;

[0023] The fixing mechanism includes a cooling bin 1, a transmission shaft 2 is connected to a bearing at the end of one side of the outside of the cooling bin 1, a wind shield 3 is transmission-connected to the outer surface of the transmission shaft 2, a handle 4 is fixedly installed at the end of the wind shield 3, an air inlet plate 5 is arranged at the bottom of the cooling bin 1, and a plurality of groups of air inlet holes 6 are connected through the inside of the air inlet plate 5. When the cooling table is in use, the transmission shaft 2 is used to drive the wind shield 3 to rotate in the horizontal direction through the handle 4, the air inlet plate 5 is used to place a tray 17, the tray 17 is used to place a workpiece 18, and the plurality of groups of air inlet holes 6 are used to provide a path for the air output by the air cooling mechanism to enter the cooling bin 1 When the operator places the workpiece 18 inside the cooling chamber 1 for cooling, the operator only needs to place the workpiece 18 on the top of the tray 17, rotate the wind shield 3 outward along the transmission shaft 2 through the handle 4, and move the tray 17 to the top of the air inlet plate 5 through the forklift, and then rotate the wind shield 5 inward along the transmission shaft 2 through the handle 4 until it is closed, and then cool the workpiece 18. This step allows the operator to place the workpiece 18 to be cooled conveniently and quickly without frequent contact with high-temperature workpieces, thereby improving work efficiency while reducing the safety hazards caused by high-temperature workpieces to users;

[0024] The air-cooling mechanism includes an air delivery channel 7. At one end of one side of the air delivery channel 7, several groups of fans 8 are installed. The output ends of several groups of fans 8 are all inside the air delivery channel 7. The top of the air delivery channel 7 is connected to the bottom of the cooling chamber 1 through an air inlet plate 5. When this cooling table is in use, the fans 8 are used to deliver cooling air into the air delivery channel 7. After the cooling air enters the air delivery channel 7, it will enter the interior of the cooling chamber 1 through several groups of air inlet holes 6 inside the air inlet plate 5 and move outward through the top of the cooling chamber 1. During this process, after the cooling air moves upward from the top of the air inlet holes 6, it will move upward through several pores of the tray 17 to cool the workpiece placed on the top of the tray 17. By inputting the cooling air into the cooling chamber 1 through several groups of air inlet holes 6 inside the air inlet plate 5 and several gaps inside the tray 17, the cooling air can evenly cool the workpiece 18 on the top of the tray 17 during the flowing process, avoiding the deformation of the workpiece 18 due to excessive temperature difference during cooling, and thus improving the cooling quality of the workpiece 18;

[0025] An output cylinder 9 is provided at the top of one side of the air delivery channel 7. The top of the output cylinder 9 is drivingly connected to an output connecting rod 10. A fixed connecting rod 11 is fixedly installed at the end of the output connecting rod 10. A fixed column 12 is provided at the end of the fixed connecting rod 11. A cover plate 13 is fixedly installed at the end of the fixed column 12. A limiting plate 14 is fixedly installed at the top of the cooling chamber 1. When this cooling table is in use, the output cylinder 9 is used to drive the output connecting rod 10 to move in the vertical direction, and drive the fixed column at the end of the fixed connecting rod 11 to move in the vertical direction through the output connecting rod 10, thereby driving the cover plate 13 to move in the vertical direction. When the cover plate 13 moves to the bottom of the limiting plate 14, the top of the cooling chamber 1 is a closed structure. When the workpiece 18 is cooled conventionally, the cover plate 13 is located at the top of the limiting plate 14. At this time, the cooling air flowing into the interior of the cooling chamber 1 will flow out through the gap between the cover plate 13 and the limiting plate 14 to form a circulation of the cooling air to cool the tool 18. When the operator needs to rapidly cool the workpiece 18, the circulating heat dissipation method of the cooling air flowing from the bottom to the top of the cooling chamber 1 cannot meet the heat dissipation conditions required by the workpiece 18. At this time, the operator drives the cover plate 13 to move to the bottom of the limiting plate 14 through the output cylinder 9 and continues to adjust the height of the cover plate 13 according to the required cooling rate until the cover plate 13 moves to a certain distance above the workpiece 18. At this time, the cooling air flowing into the cooling chamber 1 through the air inlet plate 5 cannot move to the outside of the cooling chamber 1 through the cover plate 13. The cooling air will flow into the air delivery channel 7 through the air inlet plate 5 inside the cooling chamber 1 and circulate at a high speed inside the cooling chamber 1 and the air delivery channel 7 to rapidly cool the workpiece 18, significantly improving the corresponding cooling performance;

[0026] A high-pressure valve 15 is provided at the end of the air supply channel 7. The exhaust end pipe of the high-pressure valve 15 is connected to an exhaust pipe 16. When this cooling table is in use, the high-pressure valve 15 is used to discharge the gas inside the air supply channel 7 through the exhaust pipe 16. When the operator rapidly cools the workpiece 18, the cooling air will circulate at a high speed inside the cooling chamber 1 and the air supply channel 7. However, the excessive wind pressure will cause certain damage to the cooling chamber 1 and the air supply channel 7, shortening the service life of the cooling table. Therefore, when the wind pressure reaches a certain level, it will flow into the inside of the exhaust pipe 16 through the high-pressure valve 15 and be discharged outward through the exhaust pipe 16, thereby reducing the damage caused by the excessive wind pressure to the cooling chamber 1 and the air supply channel 7 and extending the service life of the cooling table;

[0027] The limiting plate 14 is of a bucket-shaped structure. When this cooling table is in use, the top of the bucket-shaped limiting plate 14 is higher than its bottom. Therefore, when the cover plate 13 moves to the bottom of the limiting plate 14, a closed structure will be formed at the top of the cooling chamber 1. And when the cover plate 13 moves to the top of the limiting plate 14, the cooling air inside the cooling chamber 1 can move outward through the gap between the limiting plate 14 and the cover plate 13;

[0028] The cover plate 13 is slidably connected to the inner wall of the cooling chamber 1. When this cooling table is in use, since the cover plate 13 is slidably connected to the inside of the cooling chamber 1, the sealing performance can be improved when the cover plate 13 moves into the cooling table 1, reducing the leakage of the cooling air through the gap between the cover plate 13 and the inner wall of the cooling chamber 1, thereby improving the corresponding cooling effect.
