Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and particularly relates to a spinning and necking device for aluminum pipes. Background Art

[0002] The spinning and necking technology of aluminum pipes is widely used in the fields of refrigeration equipment, automotive parts and industrial pipe manufacturing. It performs necking or sealing on the end of the aluminum pipe through a rotary extrusion process to meet the requirements of sealing or connection. Traditional spinning and necking devices for aluminum pipes usually consist of a clamping mechanism, a spinning head and a driving system, which can achieve precise positioning and efficient processing of aluminum pipes. However, after the traditional spinning and necking machine finishes processing, the operator needs to manually remove the aluminum pipe from the clamping mechanism. This process not only takes time, but also easily causes worker fatigue in high-frequency production, increasing labor costs. Some automated equipment uses a robotic arm to pick up and unload, but limited by the spatial layout of the clamping mechanism, the robotic arm needs to frequently adjust its posture to avoid collision with the spinning head or fixture. This not only prolongs the unloading cycle, but also increases the system control difficulty due to complex path planning.

Detailed implementation manners

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] As Figures 1 - 12 shown, a kind of aluminum tube spinning necking device proposed in an embodiment of the present invention includes a base 1, a connecting frame 2 and a workbench frame 3 are installed on the base 1, a necking component 4 is installed on the workbench frame 3, the necking component 4 is a spinning head and is installed on the workbench frame 3, a clamping member 5 is rotatably installed on the connecting frame 2. In this embodiment, the clamping member 5 is an existing three-jaw chuck with a large aperture. One end of the aluminum tube to be clamped can pass through the back of the three-jaw chuck, exposing the unprocessed end of the aluminum tube to the back of the three-jaw chuck. The three-jaw chuck can be manually controlled or a pneumatic three-jaw chuck can be used according to needs. It also includes: A support member 6, horizontally and slidably installed on the connecting frame 2 and located at the back of the clamping member 5, which is used to clamp the inner peripheral wall of the aluminum tube. It should be noted that in this embodiment, the support member 6 only serves to support the inner peripheral wall of the aluminum tube and will not affect the rotation of the aluminum tube when the clamping member 5 rotates to drive the aluminum tube to rotate after the aluminum tube is clamped by the clamping member 5; A transportation component 7, including a conveying frame 701 inclinedly installed on the connecting frame 2, a triggering member 702 is installed on the connecting frame 2. By moving the support member 6, the end of the aluminum tube located at the back of the clamping member 5 is made to contact the triggering member 702, so that the aluminum tube falls into the conveying frame 701. Specifically, the triggering member 702 is located below the conveying frame 701. In this embodiment, as Figure 2 shown, the conveying frame 701 is inclined downward, and a box can be placed below the end of the conveying frame 701 to pick up the processed aluminum tube; The driving component 9 is installed on the connecting frame 2 and is used to drive the clamping member 5 to rotate. After the aluminum tube is installed on the clamping member 5, one end of the aluminum tube is located on the back of the three-jaw chuck. Subsequently, the inner wall side of the unprocessed end of the aluminum tube is supported by the support member 6. When the driving component 9 drives the clamping member 5 to rotate, the aluminum tube rotates in cooperation with the spinning head to perform necking processing on the aluminum tube. After the processing is completed, the three-jaw chuck releases the clamping of the aluminum tube. However, under the action of the support member 6, the aluminum tube will not fall naturally due to the action of gravity. Subsequently, the support member 6 moves away from the three-jaw chuck, thereby driving the movement of the aluminum tube. When the unprocessed end of the aluminum tube touches the trigger member 702, the aluminum tube stops moving due to the blocking of the trigger member 702, and the support member 6 continues to move until the support member 6 disengages from the aluminum tube. At this time, the aluminum tube will fall naturally due to the action of gravity and thus enter the conveying frame 701. The aluminum tube located in the conveying frame 701 slides to the end of the conveying frame 701 and thus enters the box below the conveying frame 701, completing rapid blanking. Compared with the existing manual and robotic arm methods for blanking, not only is the blanking time reduced, but also compared with the robotic arm blanking method, the occupied space is smaller.

[0020] As Figure 2 and Figure 6 shown, the structure of the support member 6 is further disclosed. The support member 6 includes a sliding frame 601 horizontally slidably installed on the connecting frame 2. An installation cylinder 602 is provided on the sliding frame 601. The installation cylinder 602 is coaxial with the clamped aluminum tube. A plurality of sliding plates 603 are slidably installed in a circular array on the installation cylinder 602. One end of the sliding plate 603 is located inside the installation cylinder 602 and a plurality of support plates 604 are elastically slidably installed. In this embodiment, the movement of the sliding frame 601 can be driven by an electric push rod. The electric push rod is installed on the connecting frame 2, and the telescopic end of the electric push rod is connected to the sliding frame 601. Specifically, a chute is provided on the sliding plate 603, and a strip plate perpendicular to it is constructed on the support plate 604. A spring piece is installed between the strip plate and the chute. An adjusting member 8 for driving the movement of the plurality of sliding plates 603 is installed on the installation cylinder 602. By the adjusting member 8, the plurality of sliding plates 603 move, driving the plurality of support plates 604 to fit against the inner wall of the aluminum tube to complete the support of the aluminum tube. The design of the spring piece enables the support plate 604 to avoid hard contact with the aluminum tube while being able to support the aluminum tube, ensuring the normal rotation of the aluminum tube. Preferably, the free end of the support plate 604 is inclined. In this way, during batch processing, when the aluminum tube needs to be replaced with the same type of aluminum tube after disengaging from the plurality of support plates 604, one end of the aluminum tube can be directly inserted onto the plurality of support plates 604 without moving the support plates 604 again, making the feeding of the aluminum tube more rapid and convenient during the batch processing.

[0021] As Figure 2 and Figure 6As shown, in order to further reduce the influence of the support plate 604 on the aluminum tube during rotation, the mounting cylinder 602 is rotatably mounted on the sliding frame 601. The mounting cylinder 602 is coupled to the clamping member 5. When the aluminum tube is reprocessed, the aluminum tube rotates synchronously with the mounting cylinder 602. During the process of processing the aluminum tube by rotation, the mounting cylinder 602 rotates synchronously with the aluminum tube, driving a plurality of support plates 604 to rotate synchronously with the aluminum tube, thereby effectively reducing the friction between the support plate 604 and the inner wall of the aluminum tube during rotation and ensuring the quality of the processed aluminum tube.

[0022] As Figure 1 , Figure 5 and Figure 8 As shown, in order to further improve the loading performance after blanking, an adjusting screw 10 is horizontally and rotatably mounted on the connecting frame 2. A limiting plate 11 is slidably mounted on the connecting frame 2. The limiting plate 11 is threadedly sleeved on the adjusting screw 10. The sliding frame 601 is located between the limiting plate 11 and the triggering member 702. After the aluminum tube is installed on the clamping member 5, at this time, the support plate 604 is inside the aluminum tube and the unprocessed end face of the aluminum tube is in contact with a plurality of sliding plates 603. Then, the adjusting screw 10 is rotated so that the limiting plate 11 is in contact with the sliding frame 601. Because the screw thread fit has self-locking property, after the subsequent sliding frame 601 moves to complete blanking, the sliding frame 601 only needs to move to be in contact with the limiting plate 11 again, which plays a positioning role. After the aluminum tube is installed on the clamping member 5 and the unprocessed end of the aluminum tube is in contact with a plurality of sliding plates 603, the aluminum tube can be positioned, ensuring that the subsequent processing of the aluminum tube can be carried out normally without the need to additionally adjust the length of the unprocessed end of the aluminum tube protruding.

[0023] As Figure 1 , Figure 2 and Figure 5 As shown, a partial structure of the driving assembly 9 is disclosed. The driving assembly 9 includes a rotating rod 901 horizontally and rotatably mounted on the connecting frame 2. A synchronous belt assembly 902 is installed between the rotating rod 901 and the clamping member 5. The synchronous belt assembly 902 is an existing belt transmission assembly. A driving motor 904 for driving the rotating rod 901 to rotate is installed on the connecting frame 2. Specifically, the driving motor 904 is located below the conveying frame 701, which does not interfere with the movement of the sliding frame 601 and the blanking of the aluminum tube, and during the process of processing the aluminum tube, iron filings are not easily splashed onto the driving motor 904, improving the rationality of the overall layout.

[0024] As Figure 1 , Figure 3 and Figure 9As shown, the connection relationship between the installation cylinder 602 and the clamping member 5 is further disclosed. A rotating cylinder 903 is rotatably installed on the sliding frame 601. The rotating cylinder 903 is slidably sleeved on the rotating rod 901. A sliding sleeve relationship is maintained between the rotating rod 901 and the rotating cylinder 903 through a sliding bar and a sliding groove. In this way, the rotating rod 901 can smoothly drive the rotating cylinder 903 to rotate. The rotating cylinder 903 is coupled to the installation cylinder 602. When the rotating rod 901 rotates, the rotating cylinder 903 rotates synchronously. Specifically, the connection between the rotating cylinder 903 and the installation cylinder 602 is achieved by using an existing belt drive mechanism. Pulley wheels are installed on both the rotating cylinder 903 and the installation cylinder 602, and a belt is synchronously installed between the two pulley wheels. In this way, when the rotating rod 901 rotates to drive the clamping member 5 to rotate, the rotating rod 901 will drive the rotating cylinder 903 to rotate. When the rotating cylinder 903 rotates, it drives the installation cylinder 602 to rotate through the belt transmission assembly, thereby realizing the synchronous rotation of the clamping member 5 and the installation cylinder 602, ensuring the synchronism between the clamping member 5 and the installation cylinder 602, and the design of the rotating cylinder 903 does not affect the horizontal movement of the sliding frame 601.

[0025] As Figure 2 , Figure 5 and Figures 9 - 11 shown, the specific structure of the trigger member 702 is disclosed. The trigger member 702 includes a connecting rod 7021 constructed on the connecting frame 2. An X-shaped frame baffle 7022 is constructed on the connecting rod 7021. The frame baffle 7022 is located between the connecting rod 7021 and the installation cylinder 602. The number of sliding plates 603 is four and they are distributed in a circular array. The cross-section of the sliding plate 603 is triangular and the surface facing the frame baffle 7022 is an inclined arc surface 7023. The design of the inclined arc surface 7023 is such that when the sliding frame 601 moves towards the frame baffle 7022, if the end of the sliding plate 603 facing the frame baffle 7022 contacts the frame baffle 7022 first, the contact between the frame baffle 7022 and the inclined arc surface 7023 will force the installation cylinder 602 to rotate, so as to ensure that the end of the aluminum tube to be unloaded can contact the frame baffle 7022. After the aluminum tube contacts the frame baffle 7022, as the sliding frame 601 continues to move, the aluminum tube is limited because it contacts the frame baffle 7022, so at this time the aluminum tube will not move and multiple support plates 604 will gradually disengage from the aluminum tube during the movement of the sliding frame 601. After the multiple support plates 604 are completely disengaged from the aluminum tube, at this time the aluminum tube will fall naturally under the action of gravity because there is no support, and thus enter the conveying frame 701. The design of the four support plates 604 ensures the stability of the support and can also ensure the normal unloading of the aluminum tube.

[0026] As Figure 1 , Figure 2 , Figure 6 and Figure 12As shown, the moving manner of the sliding carriage 601 is further disclosed. Two driving rods 12 are rotatably mounted on the connecting frame 2. Synchronous pulleys 13 are sleeved on both of the two driving rods 12. A synchronous belt 14 is synchronously mounted between the two synchronous pulleys 13. The sliding carriage 601 is elastically sleeved on the horizontal section of the synchronous belt 14. Specifically, the sliding carriage 601 is elastically sleeved on the horizontal section of the synchronous belt 14. In this embodiment, as Figure 12 shown, a set of rollers 20 is mounted on the sliding carriage 601. The rollers 20 are in contact with the horizontal section of the synchronous belt 14. A pressing plate 21 is vertically and slidably inserted into the sliding carriage 601. A set of rollers 20 is also mounted on one side of the pressing plate 21. The rollers 20 press against the bottom surface of the horizontal section of the synchronous belt 14, achieving the purpose of reducing friction. An elastic sheet 22 is mounted between the pressing plate 21 and the sliding carriage 601. The drive motor 904 is coupled to one of the driving rods 12, so that the drive motor 904 drives the corresponding driving rod 12 to rotate. That is to say, the drive motor 904 can not only drive the clamping member 5 to rotate, but also drive one of the driving rods 12 to move, causing the synchronous belt 14 to move. With the design that the sliding carriage 601 is elastically sleeved on the horizontal section of the synchronous belt 14, when the synchronous belt 14 moves, it can ensure the movement of the sliding carriage 601. And after the sliding carriage 601 contacts the limit plate 11, due to the limitation of the limit plate 11, the sliding carriage 601 will slip on the synchronous belt 14. While ensuring the movement of the sliding carriage 601, it can also ensure that when the drive motor 904 is not timely turned off after the sliding carriage 601 contacts the limit plate 11, the sliding carriage 601 will not directly contact the limit plate 11 rigidly and cause damage, protecting the drive motor 904 and the sliding carriage 601.

[0027] As Figure 1 、 Figure 3 and Figure 10 shown, the rotation manner of the drive motor 904 driving the corresponding driving rod 12 and the clamping member 5 is further disclosed. An installation rod 15 is mounted on the drive motor 904. The installation rod 15 has two free ends. A transmission rod 16 is horizontally and rotatably mounted on the connecting frame 2. An installation groove 17 is formed at one end of the rotating rod 901. A one-way bearing 18 is mounted in the installation groove 17. One end of the installation rod 15 is mounted in the one-way bearing 18, and the other end of the installation rod 15 is connected to the transmission rod 16. The transmission rod 16 is connected to one of the driving rods 12 through a bevel gear assembly 19. Specifically, a coupling rod is vertically and rotatably mounted on the connecting frame 2. Two meshing bevel gears are mounted between one end of the coupling rod and one of the driving rods 12, and meshing bevel gears are also mounted between the other end of the coupling rod and the transmission rod 16. Thus, when the installation rod 15 of the drive motor 904 rotates forward, the installation rod 15 drives the rotating rod 901 to rotate through the one-way bearing 18. At this time, since the installation rod 15 is connected to the transmission rod 16, the transmission rod 16 will also rotate at this time. Through the bevel gear assembly 19, the synchronous belt 14 will move to the left (asFigure 1 In the perspective), the sliding carriage 601 is always in contact with the limiting plate 11. When blanking is required, the mounting rod 15 rotates in the reverse direction. At this time, under the action of the one-way bearing 18, slipping will occur between the mounting rod 15 and the rotating rod 901. Therefore, the rotating rod 901 will not rotate, and thus the clamping member 5 will not rotate. However, at this time, the synchronous belt 14 will move to the right. Therefore, the sliding carriage 601 will also move to the right until one end of the aluminum tube to be blanked contacts the frame baffle 7022. During this process, the frame baffle 7022 may come into contact with the sliding plate 603 first. However, one side of the sliding plate 603 is an inclined arc surface 7023, and the design of the one-way bearing 18 enables the mounting cylinder 602 to have a rotational force in one direction. Therefore, after the frame baffle 7022 contacts the sliding plate 603, the inclined arc surface 7023 design will force the mounting cylinder 602 to rotate so that the aluminum tube to be blanked can smoothly contact the frame baffle 7022. In this way, using one driving motor 904 can achieve the rotation of the clamping member 5 and also the movement of the sliding carriage 601, which is more convenient to use.

[0028] As Figure 6 and Figure 7 shown, the specific structure of the adjusting member 8 is disclosed. The adjusting member 8 includes an external gear ring 801 rotatably sleeved on the mounting cylinder 602. One end of the external gear ring 801 is provided with a convex plate 802. A positioning rod 803 is elastically slidably mounted on the convex plate 802. As Figure 7 shown, the positioning rod 803 slidably penetrates through the convex plate 802. A ring plate is formed on the outer peripheral side of the positioning rod 803. A spring is installed between the ring plate and the inside of the convex plate 802. A plurality of positioning holes 804 are circularly arrayed on the outer peripheral side of the mounting cylinder 602. Four driving gears 805 meshing with the external gear ring 801 are rotatably mounted on the outer peripheral side of the mounting cylinder 602 in a circular array. A tooth groove 806 is provided on one side of the sliding plate 603. The four tooth grooves 806 are respectively meshed with the four driving gears 805. That is to say, by pulling the positioning rod 803 to make the positioning rod 803 disengage from the positioning hole 804, and then rotating the convex plate 802, the external gear ring 801 can be rotated. Because the external gear ring 801 meshes with a plurality of driving gears 805, the plurality of driving gears 805 will rotate synchronously. Because the driving gears 805 mesh with the tooth grooves 806 on the sliding plate 603, at this time, the plurality of sliding plates 603 will approach or move away from each other, and thus the movement of the plurality of sliding plates 603 can be controlled. The design of the elastic sliding mounting of the positioning rod 803 can effectively ensure that when the mounting cylinder 602 rotates, the positioning rod 803 will not disengage from the corresponding positioning hole 804.

[0029] Working principle: When in use, first insert the aluminum tube into the three-jaw chuck and make the unprocessed end of the aluminum tube located at the back of the three-jaw chuck. Then, clamp the aluminum tube through the three-jaw chuck. Then, the driving motor 904 makes the rotating rod 901 rotate. When the rotating rod 901 rotates forward, the synchronous belt 14 is asFigure 1 shown to move leftward (the mounting cylinder 602 will also rotate at this time but it doesn't matter), the movement of the synchronous belt 14 indirectly causes the sliding frame 601 to move leftward until the multiple sliding plates 603 on the mounting cylinder 602 come into contact (at this time, the multiple support plates 604 are located inside the aluminum tube). Subsequently, rotate the positioning rod 803 to make the external tooth ring 801 rotate through the convex plate 802, thereby causing the multiple support plates 604 to move away from each other until they fit against the inner wall of the aluminum tube. At this time, move the limit plate 11 to make the limit plate 11 fit against the sliding frame 601, which plays a positioning role. Then, start the drive motor 904 to make the mounting rod 15 rotate forward (such as Figure 1 in the perspective), the rotation of the mounting rod 15 will cause the three-jaw chuck to continuously rotate, thereby being able to meet the rotational speed requirements during the processing of the aluminum tube. At this time, the sliding frame 601 is in a slipping state with the synchronous belt 14 due to the limitation of the limit plate 11. After the processing of the aluminum tube is completed, the three-jaw chuck releases the installation of the aluminum tube. At this time, the drive motor 904 rotates in reverse to make the sliding frame 601 move rightward until the end of the aluminum tube to be unloaded contacts the frame baffle 7022 and the multiple support plates 604 are separated from the aluminum tube to be unloaded, so that the frame baffle 7022 falls onto the conveying frame 701 due to gravity. Subsequently, the drive motor 904 rotates forward again to make the sliding frame 601 fit against the limit plate 11. When loading aluminum tubes of the same model later, only need to directly sleeved multiple aluminum tubes on the multiple support plates 604 to make the aluminum tubes fit against the multiple sliding plates 603, and then clamp the aluminum tubes through the three-jaw chuck.
