Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to an annealing device for copper tube processing. Background Art

[0002] A steel pipe is a steel material with a hollow cross-section, and its length is much greater than its diameter or circumference; it has a wide range of applications in the fields of petroleum, chemical industry, power stations, ships, mechanical manufacturing, automobiles, coal, construction, etc., and is one of the key steel materials required for major equipment manufacturing.

[0003] The production process of steel pipes mainly includes steps such as material selection, melting, rolling, piercing, heat treatment, and finishing. Among them, the heat treatment processing step includes annealing treatment. The purpose of annealing treatment is to reduce the hardness and brittleness of steel pipes and improve their plasticity and toughness. After annealing treatment, the steel pipes often need to be cooled.

[0004] When the existing steel pipes are annealed and cooled, the cooling water is usually directly sprayed onto the surface of the steel pipes. It is found in production and observation that this cooling method is difficult to cool the inner wall of the steel pipes, which will reduce the contact area between the cooling water and the steel pipes, and then increase the working time required for cooling the steel pipes.

[0005] Therefore, an annealing device for copper tube processing is proposed for the above problems. Summary of the Utility Model

[0006] For this reason, the technical problem to be solved by the utility model is to overcome the problem in the prior art that it is difficult to cool the inner wall of the steel pipe, thereby increasing the working time required for cooling the steel pipe.

[0007] To solve the above technical problem, the utility model provides an annealing device for copper tube processing, including a housing; a fixing component is provided on the surface of the housing; a motor is fixedly connected to the middle of the housing; a first cooling pipe is fixedly connected to the output end of the motor; the first cooling pipe is rotationally connected to the housing and is arranged through; the middle of the first cooling pipe is symmetrically communicated with a second cooling pipe; the surfaces of the first cooling pipe and the second cooling pipe are both provided with pores; a water inlet plate is fixedly connected to the middle of the housing; the water inlet plate is rotationally connected to the first cooling pipe and is in a communicating relationship; a water inlet pipe is communicated with the top of the water inlet plate; a cooling plate is fixedly connected to the inner side wall of the housing; the surface of the cooling plate is provided with pores; an air inlet pipe is communicated with the top of the cooling plate; the air inlet pipe is arranged through the housing; through the above structure, after starting the motor, the first cooling pipe together with the second cooling pipe can rotate, realizing the simultaneous cooling of the inner and outer walls of the copper tube by the device, increasing the cooling area of the device and the copper tube, and shortening the working time required for the device to cool the copper tube.

[0008] In an embodiment of the present utility model, a plurality of connecting plates are symmetrically and fixedly connected to the middle of the second cooling pipe; a connecting rod is fixedly connected to the surface of the connecting plate; the ends of adjacent connecting rods are fixedly connected with a scraping plate; by providing the scraping plate, the scraping plate will remove the oxide layer on the surface of the copper pipe, realizing the cleaning effect of the device on the surface of the copper pipe, improving the smoothness of the surface of the copper pipe, and facilitating the subsequent processing of the copper pipe.

[0009] In an embodiment of the present utility model, a plurality of convex plates are fixedly connected to the surface of the scraping plate; the ends of the convex plates are sharp; when the copper pipe is cooled, the water pump connected to the water inlet pipe can be stopped. At this time, the cooling plate will continue to blow air onto the surface of the copper pipe, and at the same time, the scraping plate will continue to drive the convex plates to rotate together. Because the convex plates are sharp, the convex plates will scrape off the remaining water droplets on the surface of the copper pipe, improving the drying speed of the device on the surface of the copper pipe.

[0010] In an embodiment of the present utility model, a plurality of round holes are formed in the surface of the connecting plate; the round holes are arranged at equal intervals; during the flow of the air flow ejected by the cooling plate, the air flow will pass through the connecting plate. Because a plurality of round holes are formed in the surface of the connecting plate, the air flow will pass through the round holes and reach the surface of the copper pipe, and at the same time, part of the air flow will also flow out from the edge of the connecting plate, increasing the flow path of the air flow and increasing the contact area between the air flow and the copper pipe.

[0011] In an embodiment of the present utility model, a plurality of baffle plates are fixedly connected to the surface of the cooling plate; the baffle plates and the holes on the surface of the cooling plate are correspondingly arranged; the surface of the baffle plate is of an arc structure; a sealing plate is fixedly connected to the inner side wall of the baffle plate; the sealing plate is of an elastic structure; when the cooling plate is in a closed state, the sealing plate will be stretched under its own elastic force and block the holes on the surface of the cooling plate, reducing the situation of impurities in the air entering the cooling plate. When the air inlet pipe sends air into the cooling plate, the air pressure inside the cooling plate will gradually increase, causing the sealing plate to be compressed under the action of the air pressure and move closer to the baffle plate. At this time, the holes on the surface of the cooling plate are in an open state, and at the same time, the water flows ejected from the first cooling pipe and the second cooling pipe will splash. The splashed water flow will be blocked by the baffle plate when it reaches the surface of the cooling plate.

When the cooling plate is in a compressed state, the elastic force of the torsion springs will be greater than the pulling force of the pulling rope, causing the guiding plates to rotate along the baffle. At this time, the air flow ejected from the surface of the cooling plate will reach the surface of the guiding plates after flowing through the surface of the baffle, and the guiding plates will guide the flowing direction of the air flow, further increasing the flowing range of the air flow.

[0013] In an embodiment of the present utility model, a plurality of sealing balls are rotatably connected to the middle of the sealing plate; the sealing balls are of a flexible structure; the sealing balls are arranged in a circumferential array; when the sealing plate blocks the surface of the cooling plate, the sealing balls will also come into contact with the cooling plate and deform under the extrusion action, and the sealing balls will fit the surface of the cooling plate, enhancing the sealing effect of the sealing plate on the cooling plate.

[0014] In an embodiment of the present utility model, the holes on the surface of the second cooling pipe are linearly arranged; because the holes on the surface of the second cooling pipe are linearly arranged, the water flow will be more concentrated and sprayed onto the surface of the copper pipe, improving the accuracy of the water flow in cooling the copper pipe.

[0015] The above technical solutions of the present utility model have the following advantages compared with the prior art:

[0016] 1. For a copper pipe processing annealing device of the present utility model, after starting the motor, the first cooling pipe and the second cooling pipe can be rotated, realizing the simultaneous cooling of the inner and outer walls of the copper pipe by the device, increasing the cooling area of the device and the copper pipe, and shortening the working time required for the device to cool the copper pipe.

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments given are not intended to limit the present utility model.

[0026] Refer to Figures 1 to 5As shown in the figure, an annealing device for copper tube processing of the present utility model includes a housing 1; a fixing component 12 is provided on the surface of the housing 1; a motor 13 is fixedly connected to the middle of the housing 1; the output end of the motor 13 is fixedly connected to a first cooling tube 14; the first cooling tube 14 is rotatably connected to the housing 1 and is arranged through the housing 1; two second cooling tubes 15 are symmetrically communicated with the middle of the first cooling tube 14; the surfaces of the first cooling tube 14 and the second cooling tubes 15 are both provided with pores; a water inlet plate 16 is fixedly connected to the middle of the housing 1; the water inlet plate 16 is rotatably connected to the first cooling tube 14 and is in a communication relationship; a water inlet pipe 17 is communicated with the top of the water inlet plate 16; a cooling plate 18 is fixedly connected to the inner side wall of the housing 1; the surface of the cooling plate 18 is provided with pores; an air inlet pipe 19 is communicated with the top of the cooling plate 18; the air inlet pipe 19 is arranged through the housing 1; during operation, after the high-temperature copper tube is sent into the housing 1, it can be fixed by the fixing component 12. At this time, the first cooling tube 14 will be located inside the copper tube. Then, the motor 13 can be started and the water inlet pipe 17 can be externally connected to a water pump. Water flow will pass through the water inlet pipe 17, pass through the water inlet plate 16 and enter the inside of the first cooling tube 14. Part of the water flow will be diverted into the two second cooling tubes 15. After the motor 13 is started, the first cooling tube 14 will drive the second cooling tubes 15 to rotate together. The second cooling tubes 15 will perform planetary rotation around the copper tube. The holes on the surface of the second cooling tubes 15 will spray out water flow to cool the surface of the copper tube, while the first cooling tube 14 will rotate inside the copper tube. The water flow sprayed out from the holes on the surface of the first cooling tube 14 will cool the inner wall of the copper tube. At the same time, the air inlet pipe 19 can be externally connected to an air pump so that the air flow will enter the inside of the cooling plate 18 through the air inlet pipe 19. The air flow will spray out from the holes on the surface of the cooling plate 18 and reach the surface of the copper tube. The water flow sprayed out from the surface of the second cooling tubes 15 will also accelerate to reach the surface of the copper tube under the action of the air flow, realizing the simultaneous cooling of the inner and outer walls of the copper tube by the device. After the copper tube is cooled, the copper tube can be transported out by a traction device in cooperation with the fixing component 12; after the motor 13 is started, the first cooling tube 14 together with the second cooling tubes 15 can be rotated, realizing the simultaneous cooling of the inner and outer walls of the copper tube by the device, increasing the cooling area of the device and the copper tube, and shortening the working time required for the device to cool the copper tube.

[0027] Referring to Figure 2 and Figure 3As shown, a plurality of connecting plates 2 are symmetrically and fixedly connected to the middle of the second cooling pipe 15; a connecting rod 22 is fixedly connected to the surface of the connecting plate 2; the ends of adjacent connecting rods 22 are fixedly connected with a scraping plate 23; an oxide layer will be generated on the surface of the copper pipe after high-temperature annealing. When the second cooling pipe 15 rotates, it will drive the connecting plate 2, the connecting rod 22 and the scraping plate 23 to move together. When the scraping plate 23 moves, it will come into contact with the outer wall of the copper pipe, and the scraping plate 23 will scrape off the oxide layer attached to the surface of the copper pipe; by setting the scraping plate 23, the scraping plate 23 will remove the oxide layer on the surface of the copper pipe, realizing the cleaning effect of the device on the surface of the copper pipe, improving the surface finish of the copper pipe, and facilitating the subsequent processing of the copper pipe.

[0028] Refer to Figure 3 As shown, a plurality of convex plates 3 are fixedly connected to the surface of the scraping plate 23; the ends of the convex plates 3 are sharp; when the copper pipe is cooled, the water pump connected to the water inlet pipe 17 can be stopped. At this time, the cooling plate 18 will continue to blow air towards the surface of the copper pipe, and at the same time, the scraping plate 23 will continue to drive the convex plates 3 to rotate together. Because the convex plates 3 are sharp, the convex plates 3 will scrape off the remaining water droplets on the surface of the copper pipe, improving the drying speed of the device on the surface of the copper pipe.

[0029] Refer to Figure 3 As shown, a plurality of round holes 4 are formed on the surface of the connecting plate 2; the round holes 4 are arranged at equal intervals; during the flow of the air flow ejected by the cooling plate 18, it will pass through the connecting plate 2. Because a plurality of round holes 4 are formed on the surface of the connecting plate 2, the air flow will pass through the round holes 4 and reach the surface of the copper pipe, and at the same time, part of the air flow will also flow out from the edge of the connecting plate 2, increasing the flow path of the air flow and the contact area between the air flow and the copper pipe.

[0030] Refer to Figure 4 and Figure 5 As shown, a plurality of baffle plates 5 are fixedly connected to the surface of the cooling plate 18; the baffle plates 5 correspond to the holes on the surface of the cooling plate 18; the surface of the baffle plate 5 is an arc structure; a sealing plate 52 is fixedly connected to the inner side wall of the baffle plate 5; the sealing plate 52 is an elastic structure; when the cooling plate 18 is in the closed state, the sealing plate 52 will be stretched under its own elastic force and block the holes on the surface of the cooling plate 18, reducing the situation of impurities in the air entering the cooling plate 18. When the air inlet pipe 19 sends air into the cooling plate 18, the air pressure inside the cooling plate 18 will gradually increase, causing the sealing plate 52 to be compressed under the air pressure and move closer to the baffle plate 5. At this time, the holes on the surface of the cooling plate 18 are in the open state. At the same time, the water flow ejected from the first cooling pipe 14 and the second cooling pipe 15 will splash. The splashed water flow will be blocked by the baffle plate 5 when it reaches the surface of the cooling plate 18. The baffle plate 5 will reduce the water stains entering the inside of the cooling plate 18 and reduce the pollution of the cooling plate 18 by the waste water.

[0031] Refer to Figure 5As shown, a plurality of guide plates 6 are rotatably connected to the middle of the baffle 5; the guide plates 6 and the baffle 5 are connected by a torsion spring; a pull rope 62 is fixedly connected to the middle of the guide plate 6; the pull rope 62 and the sealing plate 52 are also fixedly connected; when the sealing plate 52 is in a stretched state, the guide plate 6 will be close to the surface of the cooling plate 18 under the pulling force of the pull rope 62, and the torsion spring will be in a bent state, enhancing the sealing effect of the sealing plate 52 on the surface of the cooling plate 18. When the cooling plate 18 is in a compressed state, the elastic force of the torsion spring will be greater than the pulling force of the pull rope 62, causing the guide plate 6 to rotate along the baffle 5. At this time, the air flow ejected from the surface of the cooling plate 18 will reach the surface of the guide plate 6 after flowing through the surface of the baffle 5, and the guide plate 6 will guide the air flow direction, further increasing the air flow range.

[0032] Referring to Figure 5 As shown, a plurality of sealing balls 7 are rotatably connected to the middle of the sealing plate 52; the sealing balls 7 are of flexible structure; the sealing balls 7 are arranged in a circular array; when the sealing plate 52 seals the surface of the cooling plate 18, the sealing balls 7 will also come into contact with the cooling plate 18 and deform under the extrusion, and the sealing balls 7 will fit the surface of the cooling plate 18, enhancing the sealing effect of the sealing plate 52 on the cooling plate 18.

[0033] Referring to Figure 3 As shown, the holes on the surface of the second cooling pipe 15 are linearly arranged; because the holes on the surface of the second cooling pipe 15 are linearly arranged, the water flow will be more concentrated and sprayed onto the surface of the copper pipe, improving the accuracy of the water flow in cooling the copper pipe.

[0034] Working principle: After the high-temperature copper pipe is sent into the interior of the housing 1, it can be fixed by the fixing component 12. At this time, the first cooling pipe 14 will be located inside the copper pipe. Subsequently, the motor 13 can be started and the water inlet pipe 17 can be externally connected to a water pump. The water flow will pass through the water inlet pipe 17, pass through the water inlet plate 16 and enter the interior of the first cooling pipe 14. Part of the water flow will be diverted into the two second cooling pipes 15. After the motor 13 is started, the first cooling pipe 14 will drive the second cooling pipe 15 to rotate together. The second cooling pipe 15 will perform planetary rotation around the copper pipe. The holes on the surface of the second cooling pipe 15 will spray out water flow to cool the surface of the copper pipe, while the first cooling pipe 14 will rotate inside the copper pipe, and the water flow sprayed out from the holes on the surface of the first cooling pipe 14 will cool the inner wall of the copper pipe. At the same time, the air inlet pipe 19 can be externally connected to an air pump so that the air flow will enter the cooling plate 18 through the air inlet pipe 19. The air flow will spray out from the holes on the surface of the cooling plate 18 and reach the surface of the copper pipe. The water flow sprayed out from the surface of the second cooling pipe 15 will also be accelerated to reach the surface of the copper pipe under the action of the air flow, realizing the simultaneous cooling of the inner and outer walls of the copper pipe by the device. After the copper pipe is cooled, the copper pipe can be transported out by the traction device in cooperation with the fixing component 12; an oxide layer will be generated on the surface of the copper pipe after high-temperature annealing. When the second cooling pipe 15 rotates, it will drive the connecting plate 2, the connecting rod 22 and the scraping plate 23 to move together. When the scraping plate 23 moves, it will come into contact with the outer wall of the copper pipe, and the scraping plate 23 will scrape off the oxide layer attached to the surface of the copper pipe; when the copper pipe is cooled, the water pump externally connected to the water inlet pipe 17 can be stopped. At this time, the cooling plate 18 will continue to blow air towards the surface of the copper pipe. At the same time, the scraping plate 23 will also continue to drive the convex plate 3 to rotate. Because the convex plate 3 is sharp, the convex plate 3 will scrape off the remaining water droplets on the surface of the copper pipe; during the flow of the air flow sprayed out from the cooling plate 18, it will pass through the connecting plate 2. Because a plurality of round holes 4 are formed on the surface of the connecting plate 2, the air flow will pass through the round holes 4 and reach the surface of the copper pipe. At the same time, part of the air flow will also flow out from the edge of the connecting plate 2, increasing the flow path of the air flow; when the cooling plate 18 is in the closed state, the sealing plate 52 will be stretched under its own elastic force and block the holes on the surface of the cooling plate 18, reducing the situation of impurities in the air entering the cooling plate 18. When the air inlet pipe 19 sends air into the cooling plate 18, the air pressure inside the cooling plate 18 will gradually increase, so that the sealing plate 52 will be compressed under the action of the air pressure and move towards the baffle 5. At this time, the holes on the surface of the cooling plate 18 are in the open state. At the same time, the water flow sprayed out from the first cooling pipe 14 and the second cooling pipe 15 will splash. The splashed water flow will be blocked by the baffle 5 after reaching the surface of the cooling plate 18, and the baffle 5 will reduce the water stains entering the interior of the cooling plate 18;When the sealing plate 52 is in a tensile state, it will cause the guiding plate 6 to approach the surface of the cooling plate 18 under the pulling force of the pulling rope 62, and the torsion spring will be in a bent state, enhancing the blocking effect of the sealing plate 52 on the surface of the cooling plate 18. When the cooling plate 18 is in a compressed state, the elastic force of the torsion spring will be greater than the pulling force of the pulling rope 62, causing the guiding plate 6 to rotate along the baffle 5. At this time, the air flow ejected from the surface of the cooling plate 18 will reach the surface of the guiding plate 6 after flowing through the surface of the baffle 5, and the guiding plate 6 will guide the air flow direction; when the sealing plate 52 blocks the surface of the cooling plate 18, the sealing ball 7 will also come into contact with the cooling plate 18 and deform under the extrusion, and the sealing ball 7 will fit the surface of the cooling plate 18; because the holes on the surface of the second cooling pipe 15 are linearly arranged, the water flow will be more concentrated and sprayed onto the surface of the copper pipe.
