Description

Technical Field

[0001] The utility model relates to the technical field of aluminum tube spinning, and more specifically to an aluminum tube spinning and closing device with a positioning function. Background Art

[0002] The aluminum tube spinning and closing device is a device used to process aluminum tubes. It is mainly used to spin the end of the aluminum tube to form a special closing structure. This closing structure can provide better sealing and connectivity and is often used in applications such as pipelines, cylinders, and containers.

[0003] In the existing closing device, a positioning push rod is generally provided at the front end of the spinning machine head, which is a rod-shaped object that can rise and fall vertically. The user inserts the aluminum tube into the spinning machine head, controls the positioning push rod to descend, and then pulls the aluminum tube that has been inserted into the spinning machine head outward for a distance so that the outer end of the aluminum tube abuts against the positioning push rod. The function of the positioning push rod is to assist in positioning the aluminum tube and ensure that the aluminum tube is correctly aligned with the spinning tool of the spinning machine head. This is very important for the accuracy and consistency of the spinning process, and an ideal closing structure can be obtained.

[0004] However, in the existing closing devices, the operation process of pulling out the aluminum tube to make it abut against the positioning push rod is mostly manual, which may be cumbersome and time-consuming, especially in large-scale processing, which will increase the complexity of the operation and the intensity of work. At the same time, manual operation involves placing the hands close to the area of ​​the spinning machine head, which poses certain safety risks. Especially in the case of high-speed rotation, improper operation may cause hand injuries or accidents.

[0005] Therefore, in order to solve the above problems, an aluminum tube spinning and closing device with a positioning function is proposed. Utility Model Content

[0039] Example:

[0040] See also Figure 1-2 , including a spinning machine 1 and an aluminum tube 2, a spinning machine head is installed at one end of the spinning machine 1, and an adjusting plate 3 is installed at the top of the spinning machine 1, an electric push rod 4 is installed at the end of the adjusting plate 3 close to the spinning machine head, and a positioning column 5 is fixedly connected to the output end of the electric push rod 4, the positioning column 5 is located on one side of the spinning machine head, and a positioning component 6 is provided on the side of the positioning column 5 close to the spinning machine head, the positioning component 6 includes a movable block 602, and the movable block 602 is fixedly connected to a bracket 610 at one end close to the spinning machine head, a pair of rollers 605 are rotatably connected to the inner end of the bracket 610, and a servo motor 606 is installed at the outer end of the bracket 610.

[0041] The aluminum tube spinning and closing device is a device used to process aluminum tubes. It is mainly used to spin the end of the aluminum tube to form a special closing structure. This closing structure can provide better sealing and connectivity and is often used in applications such as pipelines, cylinders, and containers.

[0042] In this solution, the spinning head at the front end of the spinning machine 1 has a clamping device, which can adjust and tightly clamp the end of the aluminum tube 2 to ensure its stability and fixity. The spinning head is equipped with a driving device, such as a motor or a pneumatic device. Through the driving device, the spinning head can apply sufficient rotational force to the clamped aluminum tube 2 to make it rotate at high speed. When the aluminum tube 2 rotates at high speed, the spinning tool of the spinning head is usually a mold that contacts the end of the aluminum tube 2 and applies a spinning force, which will cause the end of the aluminum tube 2 to undergo plastic deformation to form the desired closing structure.

[0043] The electric push rod 4 and the positioning column 5 set at the front end of the spinning head are used to assist the aluminum tube 2 in positioning, ensuring that the spinning tool of the aluminum tube 2 spinning head is correctly aligned, which is very important for the accuracy and consistency of the spinning process, and an ideal closing structure can be obtained. The upper end of the adjustment plate 3 is provided with an adjustment mechanism, so that the adjustment plate 3 can slide on the top of the spinning machine 1, so that the user can adjust the position of the positioning column 5 according to the process needs. The user inserts the aluminum tube 2 into the spinning head, starts the electric push rod 4 to control the positioning column 5 to descend, and then pulls out the aluminum tube 2 that has been inserted into the spinning head. A distance is set so that the outer end of the aluminum tube 2 is in contact with the positioning column 5, and then the aluminum tube 2 is clamped by the spinning machine head, and finally the electric push rod 4 is started to drive the positioning column 5 to reset, so as to realize the positioning of the aluminum tube 2. If this process is manually operated, the complexity of the operation and the work intensity will be increased. At the same time, manual operation involves placing the hand close to the area of ​​the spinning machine head, which poses certain safety risks. Especially in the case of high-speed rotation, improper operation may cause hand injuries or accidents. Therefore, a positioning component 6 is provided in this solution to realize automatic positioning of the aluminum tube 2 without manual intervention.

[0044] See also Figure 3-5 The positioning assembly 6 also includes a limit block 601. The end of the positioning column 5 near the spinning head is provided with a mounting groove 7. The limit block 601 is slidably connected to the inner wall of the mounting groove 7. The movable block 602 is slidably connected to the inner cavity of the limit block 601. The top of the limit block 601 is fixedly connected to a spring 604. The top of the spring 604 is fixedly connected to the inner wall of the mounting groove 7. The top of the limit block 601 is threadedly connected to a screw 603. The bottom end of the screw 603 extends to the inner cavity of the limit block 601 and is connected to the top of the movable block 602. The second pulley 608 is rotatably connected to the inner end of the bracket 610, the output end of the servo motor 606 is fixedly connected to the second pulley 608, the outer ends of a pair of rollers 605 are fixedly connected to the first pulley 607, the first pulley 607 matches the second pulley 608, the positioning assembly 6 also includes a belt 609, a pair of first pulleys 607 and the second pulley 608 are connected by the belt 609, and the outer ends of the rollers 605 are inlaid with a plurality of anti-slip strips arranged equidistantly in a ring.

[0045] After the user inserts the aluminum tube 2 into the spinning machine head, the spinning machine head does not clamp the aluminum tube 2 at this time. The user starts the electric push rod 4 to drive the positioning column 5 to move downward. The positioning column 5 comes to one side of the aluminum tube 2, and the pair of rollers 605 abuts against the top of the aluminum tube 2. As the positioning column 5 continues to move downward for a distance, the limit block 601 is blocked by the aluminum tube 2 and slides upward on the inner wall of the installation groove 7, and squeezes the spring 604, so that the elastic force applied by the spring 604 makes the pair of rollers 605 tightly abut against the top of the aluminum tube 2.

[0046] The user can loosen the screw 603 to make the movable block 602 slide in the limit block 601, thereby appropriately adjusting the distance between the bracket 610 and the spinning head to prevent the bracket 610 from colliding with the spinning head during the downward movement.

[0047] When a pair of rollers 605 abut against the top of the aluminum tube 2, the user starts the servo motor 606 to drive the second pulley 608 to rotate, and the second pulley 608 drives the belt 609 to move, thereby driving a pair of first pulleys 607 to rotate synchronously in the same direction, and the first pulley 607 drives a pair of rollers 605 to rotate on the surface of the aluminum tube 2, so that the aluminum tube 2 is moved outward from the inside of the spinning head through the friction band formed between the rollers 605 and the aluminum tube 2 until one end of the aluminum tube 2 abuts against the positioning column 5. When the aluminum tube 2 abuts against the positioning column 5, the spinning head automatically clamps the aluminum tube 2, the servo motor 606 stops working, and the electric push rod 4 drives the positioning column 5 to reset, thereby realizing the automatic positioning of the aluminum tube 2. The anti-slip strip inlaid on the surface of the roller 605 can be made of rubber, which can enhance the friction between the roller 605 and the aluminum tube 2, thereby helping the aluminum tube 2 to move out quickly.

[0048] Working principle:

[0049] When in use, the user inserts the aluminum tube 2 into the spinning machine head. At this time, the spinning machine head does not clamp the aluminum tube 2. The user starts the electric push rod 4 to drive the positioning column 5 to move downward. The positioning column 5 comes to one side of the aluminum tube 2, and the pair of rollers 605 abut against the top of the aluminum tube 2. As the positioning column 5 continues to move downward for a distance, the limit block 601 is blocked by the aluminum tube 2 and slides upward on the inner wall of the installation groove 7, and squeezes the spring 604, so that the elastic force applied by the spring 604 makes the pair of rollers 605 tightly abut against the top of the aluminum tube 2. Then the user starts the servo motor 606 to drive the second pulley 608 to rotate. The belt 609 is driven to move by the second pulley 608, thereby driving a pair of first pulleys 607 to rotate synchronously in the same direction. The first pulley 607 drives a pair of rollers 605 to rotate on the surface of the aluminum tube 2, so that the aluminum tube 2 is moved from the inside of the spinning head to the outside through the friction band formed between the rollers 605 and the aluminum tube 2 until one end of the aluminum tube 2 abuts against the positioning column 5. When the aluminum tube 2 abuts against the positioning column 5, the spinning head automatically clamps the aluminum tube 2, the servo motor 606 stops working, and the electric push rod 4 drives the positioning column 5 to reset, thereby realizing automatic positioning of the aluminum tube 2.

[0050] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
