Description

Technical Field

[0001] The utility model belongs to the technical field of copper tube heat treatment, and particularly relates to a cooling device for copper tube heat treatment. Background Technique

[0002] During the production process of copper tubes, heat treatment processes will be passed through to improve the physical and mechanical properties of copper tubes. Heat treatment can eliminate internal stress, improve the grain structure (the improvement of the grain structure helps to prevent oxidation and ensure the quality of copper tubes), improve the hardness and strength of copper tubes, and at the same time can also improve the processing performance of copper tubes. After the heat treatment of copper tubes, different cooling is required according to different performance requirements, and a cooling device is needed during cooling.

[0003] When cooling copper tubes, a cooling pool will be used. The existing method is to uniformly lift the copper tubes into the cooling pool to cool the copper tubes. However, after the copper tubes are lifted in, there is a lack of a mechanism to restrict the copper tubes, and it is more troublesome to fish out the copper tubes. Moreover, multiple groups of copper tubes are close to each other, resulting in a decrease in the cooling effect on the surface of the copper tubes where they are close, and further affecting the heat treatment effect of the copper tubes. Therefore, a technical measure is proposed to solve the problems of the existing lack of a mechanism to restrict the copper tubes, the trouble in fishing out the copper tubes from the cooling pool, the mutual proximity of multiple groups of copper tubes, the resulting decrease in the cooling effect on the surface of the copper tubes where they are close, and the further impact on the heat treatment effect of the copper tubes.

[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the present utility model provides a cooling device for copper tube heat treatment, including a cooling pool and a lifting plate. The cooling pool is filled with a coolant inside. At both ends of the upper surface of the lifting plate, two groups of symmetrically distributed columns are installed. Below the interior of the columns, a bearing rod is installed. Tooth grooves are formed on the side surface of the bearing rod. The bearing rod is slidably connected with a plurality of movable limiting components. Thanks to the arrangement of the movable limiting components, it is convenient to adjust the distance between the movable limiting components according to the size of the copper tube, so that more copper tubes can be placed, improving the use efficiency of the device. And the movable limiting components limit the copper tubes to prevent the position of the copper tubes from shifting inside the cooling pool, facilitating the fishing out of the copper tubes from the cooling pool. At the same time, the movable limiting components reduce the contact area between the copper tubes, preventing the cooling effect on the surface where the copper tubes are in contact from decreasing and ensuring the heat treatment effect of the copper tubes.

[0008] Further, a square column is installed on the upper part of the cooling pool. A chute is formed on the square column. A motor is installed at the bottom of the square column. The motor is connected with a screw rod. The screw rod is rotatably connected with the square column.

A spring is installed on the side of the pressing plate facing the pull rod, and the other end of the spring is installed inside the tube body.

[0012] Even further, a connecting rod is installed at the end of the pressing plate away from the round rod. The other end of the connecting rod is connected with a clamping block. A plurality of uniformly distributed teeth are formed on the side of the clamping block away from the connecting rod.

[0013] Even further, the teeth are in snap-fit with the tooth grooves, the tube body is adapted to the first card slot, and the isolation rod is adapted to the second card slot. Thanks to the arrangement of the isolation rod, multiple copper tubes are separated, reducing the contact area between the copper tubes.

[0016] With the setting of the movable limiting component in the utility model, it is convenient to adjust the distance between the movable limiting components according to the size of the copper pipe, so that more copper pipes can be placed, improving the use efficiency of the device. And the movable limiting component limits the copper pipe to prevent the position of the copper pipe from shifting inside the cooling pool, facilitating the fishing out of the copper pipe from the cooling pool. At the same time, the movable limiting component reduces the contact area between the copper pipes, preventing the cooling effect on the surface where the copper pipes are in contact from decreasing and ensuring the heat treatment effect of the copper pipes. Adjust the distance of the movable limiting component according to the size of the copper pipe to be cooled.

[0024] This specific embodiment is a cooling device for copper tube heat treatment, and its structural schematic diagram is as Figure 1 and Figure 2 shown. There are a cooling pool 1 and a lifting plate 4. The cooling pool 1 is filled with coolant inside. At both ends of the upper surface of the lifting plate 4, two groups of symmetrically distributed columns 3 are installed. Below the interior of the column 3, a bearing rod 12 is installed. A tooth groove 13 is provided on the side surface of the bearing rod 12. The bearing rod 12 is slidably connected with a plurality of movable limiting components 2. Above the cooling pool 1, a square column 5 is installed. A chute 7 is provided on the square column 5. At the bottom of the square column 5, a motor 6 is installed. The motor 6 is connected with a screw rod 8. The screw rod 8 is rotatably connected with the square column 5. The screw rod 8 is threadedly connected with a connecting plate 9. The connecting plate 9 is L-shaped. A fixed connection is provided between the lifting plate 4 and the connecting plate 9. A second card slot 11 is provided at the bottom of the column 3. A first card slot 10 is provided at the lower end of the side surface of the column 3. The movable limiting component 2 is in suitable fit with the first card slot 10 and the second card slot 11. When cooling the copper tube, first, coolant is injected into the cooling pool 1. The distance of the movable limiting component 2 is adjusted according to the size of the copper tube to be cooled. Subsequently, the copper tube is lifted and placed into the gap between the movable limiting components 2. The motor 6 is started. The start of the motor 6 drives the screw rod 8 to rotate. The rotation of the screw rod 8 drives the connecting plate 9 to move downward. The downward movement of the connecting plate 9 drives the lifting plate 4 to move downward into the cooling pool 1. The downward movement of the lifting plate 4 drives the copper tube into the cooling pool 1, completing the cooling of the copper tube.

[0025] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The shown movable limiting component 2 includes a slip ring 201, which is slidably adapted to the bearing rod 12. An isolating rod 202 is installed on the upper surface of the slip ring 201, and a tube body 204 is installed on the side surface of the slip ring 201. A round rod 206 is slidably connected to the tube body 204. One end of the round rod 206 is connected to a pull rod 203, and the other end of the round rod 206 away from the pull rod 203 is connected to a pressing plate 210. A spring 207 is installed on the side of the pressing plate 210 facing the pull rod 203, and the other end of the spring 207 is installed inside the tube body 204. A connecting rod 205 is installed at the end of the pressing plate 210 away from the round rod 206, and the other end of the connecting rod 205 is connected to a clamping block 208. A plurality of evenly distributed clamping teeth 209 are provided on the side of the clamping block 208 away from the connecting rod 205, and the clamping teeth 209 are engaged and adapted to the tooth grooves 13. The tube body 204 is adapted to the first card slot 10, and the isolating rod 202 is adapted to the second card slot 11. Pull the pull rod 203 outwards, the outward movement of the pull rod 203 drives the outward movement of the round rod 206, the outward movement of the round rod 206 drives the outward movement of the pressing plate 210. When the pressing plate 210 moves outwards, the spring 207 is compressed. The outward movement of the pressing plate 210 synchronously drives the outward movement of the connecting rod 205, the outward movement of the connecting rod 205 drives the clamping block 208 away from the tooth groove 13, and the clamping block 208 moving away from the tooth groove 13 drives the clamping teeth 209 away from the tooth groove 13, releasing the limit on the movable limiting component 2. At this time, drive the isolating rod 202 to move along the horizontal direction, and the movement of the isolating rod 202 drives the movement of the slip ring 201. When the distance between multiple slip rings 201 is adapted to the size of the copper tube, release the pull rod 203, and under the rebounding action of the spring 207, the clamping teeth 209 are snapped into the tooth groove 13 to complete the fixation of the movable limiting component 2.

[0026] Working principle: When cooling the copper pipe, first inject the coolant into the cooling pool 1. Adjust the distance of the movable limit component 2 according to the size of the copper pipe to be cooled (the redundant movable limit component 2 is inserted into the column 3 without hindering the copper pipe). The specific method is to pull the pull rod 203 outwards. The outward movement of the pull rod 203 drives the round rod 206 to move outwards. The outward movement of the round rod 206 drives the pressing plate 210 to move outwards. When the pressing plate 210 moves outwards, it compresses the spring 207. The outward movement of the pressing plate 210 synchronously drives the connecting rod 205 to move outwards. The outward movement of the connecting rod 205 drives the block 208 away from the tooth groove 13. The block 208 moving away from the tooth groove 13 drives the tooth 209 away from the tooth groove 13, releasing the limit on the movable limit component 2. At this time, drive the isolation rod 202 to move along the horizontal direction. The movement of the isolation rod 202 drives the slip ring 201 to move. When the distance between multiple slip rings 201 is adapted to the size of the copper pipe, release the pull rod 203. Under the elastic return of the spring 207, the tooth 209 is inserted into the tooth groove 13, completing the fixation of the movable limit component 2. Through the setting of the movable limit component 2, it is convenient to adjust the distance between the movable limit components 2 according to the size of the copper pipe, so that more copper pipes can be placed, improving the use efficiency of the device. And the movable limit component 2 limits the copper pipe to prevent the position of the copper pipe from shifting inside the cooling pool 1, facilitating the fishing out of the copper pipe from the cooling pool 1. At the same time, the movable limit component 2 reduces the contact area between the copper pipes, preventing the cooling effect on the surface where the copper pipes are in contact from decreasing and ensuring the heat treatment effect of the copper pipes;

[0027] Subsequently, lift the copper pipe into the gap between the movable limit components 2, start the motor 6. The start of the motor 6 drives the screw rod 8 to rotate. The rotation of the screw rod 8 drives the connecting plate 9 to move downwards. The downward movement of the connecting plate 9 drives the lifting plate 4 to move downwards into the cooling pool 1. The downward movement of the lifting plate 4 drives the copper pipe into the cooling pool 1 to complete the cooling of the copper pipe.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
