Description

Technical Field

[0001] This utility model belongs to the field of aluminum tube production technology, and in particular relates to a tube bending equipment for aluminum tube production. Background Technology

[0002] Aluminum tubes are a type of non-ferrous metal tube, referring to hollow metal tubular materials made of pure aluminum or aluminum alloy through extrusion processing. When used for pipeline laying and repair in power construction, railway construction, boilers, bridges, ships, furniture, decoration, etc., aluminum tubes need to be bent. Therefore, tube bending machines are an indispensable piece of equipment in the production process of aluminum tubes.

[0003] Most existing aluminum tube bending equipment uses a screw rotation to clamp and unlock the aluminum tube. When dealing with aluminum tubes of different sizes in different batches, the number of screw rotations needs to be adjusted to stably clamp the tube without damaging it due to excessive screw rotation. Most existing aluminum tube bending equipment uses electric power to drive the screw rotation to improve processing efficiency; however, adjusting the rotation number of electric screws is cumbersome and affects work efficiency when switching between production of aluminum tubes of different diameters.

[0004] Therefore, we propose a pipe bending machine for aluminum tube production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low work efficiency when switching between production of aluminum tubes of different diameters in the prior art, and to propose a tube bending device for aluminum tube production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tube bending device for aluminum tube production includes a workbench. A hydraulic turntable is mounted on one side of the top surface of the workbench. A rotating arm is fixedly connected to one side of the hydraulic turntable. An installation groove is formed on the top surface of the rotating arm. Two parallel rotating rods are rotatably mounted on both sides of the installation groove. A movable plate is rotatably connected to the top ends of the four rotating rods. A drive assembly for moving the movable plate is provided on one side of the installation groove. A fixing block is fixedly connected to the center of the top surface of the movable plate. A lead screw is threaded through the center of the fixing block. A pressure plate is rotatably connected to the end of the lead screw facing the hydraulic turntable. The pressure plate is slidably mounted on the top surface of the movable plate. A rotating disk is detachably fixedly connected to the top of the hydraulic turntable. An installation groove is formed on one side of the rotating disk, and a fixing plate that matches the pressure plate is detachably fixedly connected within the installation groove. Grooves for matching aluminum tubes are formed on the sides of the fixing plate and the rotating disk, and the side of the fixing plate with the groove is tangent to the side of the rotating disk. A support assembly for auxiliary aluminum tubes is also provided on the top surface of the workbench.

[0008] Preferably, an auxiliary block is fixedly provided on the top surface of the workbench between the support assembly and the rotating disk, and the auxiliary block is attached to the side wall of the aluminum tube.

[0009] Preferably, the top surface of the movable plate is provided with a sliding groove, and the bottom surface of the pressure plate is fixedly connected with a slider that matches the sliding groove.

[0010] Preferably, the top and bottom surfaces of one side of the rotating disk are provided with a first groove for a fixing plate, and the middle of the fixing plate is provided with a second groove for a rotating disk. The rotating disk and the fixing plate are fixedly connected by bolts.

[0011] Preferably, the thread of the lead screw is a trapezoidal thread, and the slope is less than the friction angle.

[0012] Preferably, the lead screw is located on the side of the pressure plate away from the point where the rotating disk is tangent to the fixed plate.

[0013] In summary, the technical effects and advantages of this utility model are as follows: This bending equipment for aluminum tube production uses four rotating rods in conjunction with a drive assembly to move the movable plate, which, in conjunction with a pressure plate, clamps the aluminum tube. The movement of the pressure plate on the movable plate is adjusted by rotating a screw to accommodate aluminum tubes of different diameters. Compared with existing devices, this avoids the problem of cumbersome screw advance distance adjustment caused by relying solely on a drive assembly and screw, thus improving the efficiency of production switching.

[0014] In addition, by using four rotating rods in conjunction with the drive assembly, the pressure plate can extend from the mounting slot when clamping the aluminum tube, and the movable plate can retract into the mounting slot when unlocking the aluminum tube, which facilitates the picking up and placing of the aluminum tube. Compared with existing devices, this reduces the impact of the pressure plate on the picking up and placing of the aluminum tube, and improves practicality and efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A pipe bending device for aluminum tube production includes a workbench 1. A hydraulic turntable 2 is mounted on one side of the top surface of the workbench 1. A rotating arm 3 is fixedly connected to one side of the hydraulic turntable 2. The top surface of the rotating arm 3 has an installation groove 4. Two parallel rotating rods 5 are rotatably mounted on both sides of the installation groove 4. The top ends of the four rotating rods 5 are rotatably connected to a movable plate 6. A drive assembly 7 for moving the movable plate 6 is provided on one side of the installation groove 4. A fixing block 8 is fixedly connected to the middle of the top surface of the movable plate 6. A lead screw 9 is threaded through the middle of the fixing block 8. A pressure plate 10 is rotatably connected to one end of the lead screw 9 facing the hydraulic turntable 2. The pressure plate 10 is slidably mounted on the top surface of the movable plate 6. A rotating disk 11 is detachably fixedly connected to the top of the hydraulic turntable 2. A mounting groove 4 is provided on one side of the rotating disk 11, and a fixing plate 12 that matches the pressure plate 10 is detachably fixedly connected in the mounting groove 4. The fixing plate 12 and the side of the rotating disk 11 have grooves 13 that match the aluminum tubes, and the side of the fixing plate 12 with the grooves 13 is tangent to the side of the rotating disk 11. The top surface of the workbench 1 is also provided with a support component 14 for auxiliary aluminum tubes that work with the workbench 1. The support component 14 is existing technology and can provide support for one end of the aluminum tube, which facilitates the bending process of the aluminum tube. It will not be described in detail here.

[0021] Reference Figure 1-3 The bending equipment used for aluminum tube production, during adjustment, first places one end of the aluminum tube between the pressure plate 10 and the fixed plate 12 and slightly lifts it. The moving plate 6 is then moved to its highest point by the drive assembly 7. At this point, the lead screw 9 is rotated until the pressure plate 10 and the fixed plate 12 fix the aluminum tube, thus adjusting the position of the fixed plate 12. In use, simply align the starting point of the section of the aluminum tube to be bent with the tangent point between the fixed plate 12 and the rotating disk 11. Then, the moving plate 6 is moved by the drive assembly 7 until it reaches its maximum stroke, clamping the aluminum tube. Rotating the hydraulic turntable 2 then drives the rotating arm 3 and the rotating disk 11 to rotate, thus bending the aluminum tube.

[0022] It should be noted that one side of the rotating rod 5 should be in contact with the inner wall of the mounting groove 4, and the other side should be in contact with the movable plate 6. When clamping the aluminum tube, the movable plate 6 should still be located in the mounting groove 4 to ensure the stability of the movable plate 6 and avoid damage to the movable plate 6 and the rotating rod 5 due to the large force generated during the bending of the aluminum tube.

[0023] The drive assembly 7 can use an electric actuator. When the electric actuator moves to its maximum stroke, it is considered to clamp and fix the aluminum tube; when the electric actuator moves to its minimum stroke, it is considered to unlock the aluminum tube.

[0024] Reference Figure 1-3 An auxiliary block 15 is fixedly installed on the top surface of the workbench 1, located between the support assembly 14 and the rotating disk 11, and the auxiliary block 15 is in contact with the side wall of the aluminum tube. The auxiliary block 15 provides a limit for bending the aluminum tube, thereby improving stability. The position of the auxiliary block 15 on the top surface of the workbench 1 can be adjusted by setting multiple mounting holes or adjusting screws, thus accommodating aluminum tubes of different diameters.

[0025] The top surface of the movable plate 6 is provided with a sliding groove 16, and the bottom surface of the pressure plate 10 is fixedly connected with a slider that matches the sliding groove 16. The sliding groove 16 and the slider together limit the movement of the pressure plate 10, preventing the pressure plate 10 from tilting due to uneven force, and improving the bending stability of the aluminum tube.

[0026] The rotating disk 11 has a first groove 17 on both its top and bottom surfaces to mate with the fixing plate 12. The fixing plate 12 has a second groove in its center to mate with the rotating disk 11. The rotating disk 11 and the fixing plate 12 are fixedly connected by bolts 18. The first groove 17 and the second groove, along with the bolts 18, enable a detachable connection between the rotating disk 11 and the fixing plate 12. It should be noted that when processing pipes with different radii of curvature, rotating disks 11 of different sizes are required for bending. The detachable design of the rotating disk 11 and the fixing plate 12 facilitates maintenance and improves the fit between the fixing plate 12 and the pressure plate 10, thereby enhancing bending stability.

[0027] The lead screw 9 has a trapezoidal thread with a slope less than the friction angle. This ensures that when the lead screw 9 stops rotating, it self-locks with the fixed block 8, thus supporting the pressure plate 10. This eliminates the need for an additional locking component to lock the lead screw 9, reducing costs and improving efficiency.

[0028] Since the point where the rotating disk 11 is tangent to the fixed plate 12 is the starting point of the aluminum tube bending, when the aluminum tube is bent, pressure is applied to the side of the pressure plate 10 away from the support assembly 14. The lead screw 9 is located on the side of the pressure plate 10 away from the point where the rotating disk 11 is tangent to the fixed plate 12, thereby shortening the lever arm and improving the stability of the rotational connection between the pressure plate 10 and the lead screw 9.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
