Description

Technical Field

[0001] This utility model relates to the technical field of copper tube production equipment, and in particular to a continuous rolling device for copper tubes. Background Technology

[0002] The continuous rolling mill for copper tubes is mainly used in the production process of copper tubes. Through continuous rolling process, copper billets are gradually rolled into copper tubes of the required specifications. The mill adopts an advanced control system and precise process parameters, which can improve production efficiency, reduce energy consumption, and ensure the dimensional accuracy and surface quality of copper tubes. With the development of technology, the continuous rolling mill is constantly being optimized and is gradually developing towards automation, high efficiency, and low loss.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing continuous rolling equipment for copper tubes cannot adapt to the rolling requirements of copper tubes of different specifications, thus failing to improve production efficiency and product dimensional accuracy. When it is necessary to produce copper tubes of different specifications, if the rolling equipment cannot be adjusted quickly and accurately, a lot of time needs to be spent on changing equipment parameters, replacing molds, etc. Due to the poor adaptability of the equipment, enterprises may not be able to flexibly adjust their production plans in a timely manner according to changes in market demand. Copper tubes of different specifications have strict requirements for dimensional accuracy. If the rolling equipment cannot accurately control the rolling process, it may cause the outer diameter, wall thickness, and other dimensional parameters of the copper tubes to not meet the standards.

[0004] Therefore, this utility model proposes a continuous rolling device for copper tubes to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a continuous rolling device for copper tubes.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a continuous rolling apparatus for copper tubes, comprising:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-4 As shown, this embodiment provides a technical solution: a continuous rolling apparatus for copper tubes, comprising:

[0034] Base plate 1;

[0035] The rolling assembly 2 includes a support base 21 fixed on the base plate 1. A first drive motor 22 is mounted on the support base 21. A first work roll 23 is fixed to the output end of the first drive motor 22. A first gear 24 is fixed to the end of the first work roll 23 away from the first drive motor 22. A second gear 25 meshes with the first gear 24. A first rotating block 26 is provided on the second gear 25. A second rotating block 27 is rotatably connected to the first rotating block 26. A third gear 28 is provided on the second rotating block 27. The third gear 28 meshes with the second gear 25. A fourth gear 29 is rotatably connected to the second rotating block 27. The fourth gear 29 meshes with the third gear 28. A connecting block 210 is rotatably connected to the fourth gear 29. A second work roll 211 is rotatably connected to the connecting block 210. The connecting block 210 is slidably connected inside the support base 21. A hydraulic push rod 212 is mounted on the top of the support base 21. The output end of the hydraulic push rod 212 is fixed to the connecting block 210.

[0036] Positioning component 3 includes a support block 31 fixed to one side of support base 21. A first rotating seat 32 is rotatably connected to support block 31, and a third rotating block 33 is rotatably connected to support block 31. A limit sleeve 34 is rotatably connected to the first rotating seat 32, and the third rotating block 33 is slidably connected within the limit sleeve 34. During copper tube rolling, the first drive motor 22 drives the first work roll 23 to rotate. Through the meshing of the first gear 24 and the second gear 25, the first rotating block 26 is driven to move. The third gear 28 on the second rotating block 27 meshes with the second gear 25, and the fourth gear 29 meshes with the third gear 28, forming a multi-stage gear transmission system. The system ensures smooth power transmission and uniform torque distribution. The hydraulic push rod 212 pushes the connecting block 210 to slide along the limiting groove 213 in the support seat 21, driving the second working roll 211 to precisely adjust its position and form an adjustable rolling gap with the first working roll 23. The sliding of the limiting block 214 in the limiting groove 213 ensures the stability of the adjustment process. The first guide roller 216 on the support plate 215 guides the copper tube to smoothly enter the rolling area. The positioning component 3 drives the limiting sleeve 34 to rotate through the first rotating seat 32 on the support block 31. The third rotating block 33 slides in the limiting sleeve 34, and the ball bearing 36 on the positioning wheel 35 achieves precise positioning of the copper tube.

[0037] The above solutions still have the problem of not being able to prevent the copper tube from deforming due to overheating after the copper tube rolling process is completed, such as... Figures 1-3As shown: A limiting groove 213 is provided on the support base 21, and a limiting block 214 is fixed on the side of the connecting block 210 near the limiting groove 213. The limiting block 214 is slidably connected in the limiting groove 213. A support plate 215 is fixed on one side of the support base 21, and a first guide roller 216 is rotatably connected to the support plate 215. The limiting groove 213 provided on the support base 21 cooperates with the limiting block 214 on the connecting block 210 to ensure that the connecting block 210 slides stably along a predetermined trajectory under the drive of the hydraulic push rod 212, avoiding deviation or shaking. The first guide roller 216 on the support plate 215 assists the copper tube to enter the rolling area smoothly, reducing friction and deformation. This structure improves the stability of the rolling process, ensures the dimensional accuracy of the copper tube, and extends the service life of the equipment.

[0038] like Figure 1 as well as Figure 4 As shown, a positioning wheel 35 is rotatably connected to the third rotating block 33, and a ball bearing 36 is provided on the positioning wheel 35. A second rotating seat 37 is rotatably connected to the support block 31, and a screw 38 is provided on the second rotating seat 37. The ball bearing 36 on the positioning wheel 35 reduces the feeding resistance of the copper tube and ensures smooth conveying. The second drive motor 310 drives the screw 38 to rotate, causing the third rotating seat 39 to move along the screw 38, thereby adjusting the position of the first rotating seat 32 to accommodate copper tubes of different diameters. This structure achieves automated adjustment, improves rolling adaptability, and reduces manual intervention. The other end of the rod 38 is threadedly connected to a third rotating seat 39, which is rotatably connected to a first rotating seat 32. A second drive motor 310 is mounted on a second rotating seat 37, and the screw 38 is fixed to the output end of the second drive motor 310. The second drive motor 310 drives the screw 38 to rotate, causing the third rotating seat 39 to move under the action of the thread, thereby adjusting the position of the first rotating seat 32 and the limiting sleeve 34. This mechanism enables precise adjustment of the copper tube feeding path, ensures centering during the rolling process, avoids copper tube deviation, and improves the quality of the finished product.

[0039] like Figure 1 as well as Figure 5As shown, a cooling assembly 4 is provided on the side of the base plate 1 away from the positioning assembly 3. The cooling assembly 4 includes a cooling cylinder 41 fixed on the base plate 1, an air guide plate 42 fixed inside the cooling cylinder 41, a vent 43 on the cooling cylinder 41, and a second guide roller 44 rotatably connected to the cooling cylinder 41. The air guide plate 42 inside the cooling cylinder 41 guides the airflow to be evenly distributed, improving cooling efficiency. The vent 43 ensures air circulation. The second guide roller 44 assists the copper tube to pass smoothly through the cooling zone. This structure avoids deformation of the copper tube due to local overheating, ensuring the stability of the material properties after rolling. The base plate 1 is adjacent to... A water tank 45 is fixed to one side near the bottom of the cooling cylinder 41. A water guide pipe 46 is fixed to the water tank 45. The other end of the water guide pipe 46 is fixed to the top of the cooling cylinder 41. A water pump 47 is installed on the side of the water tank 45 near the water guide pipe 46. The water guide pipe 46 is located at the output end of the water pump 47. A fan 48 is installed on one side of the top of the cooling cylinder 41. The water pump 47 transports the cooling water in the water tank 45 to the top of the cooling cylinder 41 through the water guide pipe 46 to form a spray or water curtain cooling. The fan 48 accelerates the airflow and enhances the heat dissipation effect. This cooling system has efficient temperature control and improves the surface quality of the product.

[0040] Working principle:

[0041] like Figures 1-5As shown, during the copper tube rolling process, the copper tube to be rolled is first placed in the support block 31. The second drive motor 310 is started, driving the screw 38 to rotate, causing the third rotating seat 39 to move along the screw 38, thereby adjusting the position of the first rotating seat 32. The first rotating seat 32 on the support block 31 drives the limiting sleeve 34 to rotate, and the third rotating block 33 slides within the limiting sleeve 34. The ball bearings 36 on the positioning wheel 35 reduce the feeding resistance of the copper tube, ensuring smooth conveying and adapting to copper tubes of different diameters, achieving automated adjustment. Subsequently, the first drive motor 22 starts working, driving the first working roller 23 to rotate at high speed. The first working roller 23 drives the first gear 24 at the end to rotate synchronously. The first gear 24 meshes tightly with the second gear 25, thereby driving the first rotating block 26 to move. The third gear 28 on the second rotating block 27 continuously meshes with the second gear 25 and rotates under the drive of the first rotating block 26. The fourth gear 29 meshes with the third gear 25. 8. Engagement forms a multi-stage gear transmission system, achieving smooth power transmission and uniform torque distribution. Hydraulic push rod 212 pushes connecting block 210 to slide within the limiting groove 213 of support seat 21. Under the constraint of limiting groove 213, limiting block 214 ensures stable movement of connecting block 210, thereby driving the second working roll 211 to precisely adjust its position, forming a rolling gap that can adapt to different pipe diameters. The first guide roller 216 on support plate 215 guides the copper tube to smoothly enter the rolling area, reducing the risk of friction and deformation. The rolled copper tube enters the cooling assembly 4. The air guide plate 42 in the cooling cylinder 41 guides the airflow to be evenly distributed. The ventilation port 43 ensures air circulation. The water pump 47 transports the cooling water in the water tank 45 to the top of the cooling cylinder 41 through the water guide pipe 46, forming a spray or water curtain cooling. The fan 48 accelerates the airflow and enhances the heat dissipation effect. The second guide roller 44 assists the copper tube to smoothly pass through the cooling zone, avoiding deformation of the copper tube due to local overheating, ensuring stable material properties after rolling, and improving the surface quality of the product.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
