Description

Technical Field

[0001] This utility model belongs to the field of aluminum tube end shaping technology, specifically an aluminum tube cutting end shaping mechanism. Background Technology

[0002] In modern industrial production, aluminum tubes are widely used in aerospace, automotive manufacturing, construction engineering, and electronic equipment due to their excellent physical properties, such as light weight, high strength, and good corrosion resistance. In these applications, aluminum tubes often need to be cut and processed according to specific usage requirements to adapt to different assembly sizes and functional requirements.

[0003] However, the cutting process of aluminum tubes is not without its challenges, and the condition of the cut ends presents numerous difficulties for subsequent production processes. From a microscopic perspective, the high heat generated during cutting causes localized melting and resolidification of the metal at the tube ends, resulting in a rough microstructure on the end surface, producing numerous tiny protrusions and depressions. These microscopic defects not only reduce the surface finish of the aluminum tube ends but also affect the tightness and stability of connections when subsequently joined with other components due to the reduced contact area. From a macroscopic perspective, the mechanical stress generated during cutting often causes deformation of the aluminum tube ends, significantly impacting their quality.

[0004] Currently, the traditional method for processing the cut ends of aluminum tubes is manual grinding and shaping. This traditional manual method is problematic in two ways: firstly, workers spend long hours holding grinding (or shaping) tools to process the aluminum tube ends, resulting in extremely high labor intensity and very low efficiency; secondly, the quality of manual grinding (or shaping) heavily depends on the individual worker's skill and work condition, leading to significant differences in grinding (shaping) results between different workers, and even among the same worker at different times, making it impossible to guarantee consistent quality in the shaping of the aluminum tube ends. Utility Model Content

[0005] To address the problems of low efficiency and inconsistent processing quality in traditional manual processing of aluminum tube cutting ends, this utility model provides an aluminum tube cutting end shaping mechanism.

[0006] This utility model is achieved through the following technical solution:

[0007] A shaping mechanism for the cut end of an aluminum tube includes a support frame and a movable frame arranged opposite to each other. A chuck capable of clamping and positioning the aluminum tube is positioned on the support frame. The movable frame is slidably connected to the support frame and a motor is positioned on the movable frame. The output shaft of the motor faces the chuck and is coaxial with the chuck. A shaping component is positioned on the output shaft of the motor. The shaping component includes a mounting plate positioned on the output shaft of the motor. A shaping roller capable of rolling and pressing to shape the inner wall of the end of the aluminum tube is rotatably mounted on the mounting plate. A grinding block capable of grinding the end of the aluminum tube is positioned on the mounting plate.

[0008] A further improvement of this utility model is that several shaping rollers are provided, and they are evenly spaced in a ring relative to the motor output shaft.

[0009] A further improvement of this utility model is that the outer edge of the shaping roller near the chuck is provided with a second chamfer.

[0010] A further improvement of this utility model is that several grinding blocks are provided, and they are arranged in correspondence with the shaping rollers.

[0011] A further improvement of this utility model is that the grinding block has a third chamfer on the left and right edges of the side near the chuck.

[0012] A further improvement of this utility model is that the mounting plate is connected to the center of the motor output shaft end by mounting bolts.

[0013] A further improvement of this utility model is that the non-center position of the motor output shaft end is positioned and installed with a positioning pin between it and the mounting plate.

[0014] A further improvement of this utility model is that the movable frame is connected and installed with several guide rods that slide and insert with the support frame for guidance.

[0015] A further improvement of this utility model is that the chuck is provided with several claws arranged in a circular array, and the inner clamping surface of the claws is covered with a rubber protective pad.

[0016] A further improvement of this utility model is that the support frame has a through hole corresponding to the chuck, and the side of the through hole away from the movable frame has a first chamfer.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] In use, the aluminum tube to be shaped is clamped and fixed in place by a chuck, with the tube end extending a short distance towards the shaping component. The motor is started, driving the shaping component to rotate. The moving frame is then slowly moved towards the support frame until the rotating shaping roller contacts and presses against the inner wall of the aluminum tube end, rotating along with it. This achieves high efficiency and precision in shaping the cut end of the aluminum tube. As the moving frame moves towards the support frame, the final rotating grinding block contacts and grinds the aluminum tube end. The overall structure is simple, easy to use, and highly efficient in shaping and grinding aluminum tube ends, effectively ensuring consistent quality in the treatment of aluminum tube ends.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] like Figure 1-4As shown, this utility model discloses an aluminum tube cutting end shaping mechanism, including a support frame 1 and a movable frame 2 arranged opposite to each other. The support frame 1 has an L-shaped bent structure and several support legs 11 at its bottom. A chuck 4 capable of clamping and positioning the aluminum tube is positioned on the vertical section of the support frame 1. The axis of the chuck 4 is in the front-to-back horizontal direction. The movable frame 2 is slidably connected to the support frame 1 in the left-to-right direction, and a motor 5 is positioned on the movable frame 2. The output shaft of the motor 5 faces the chuck 4 and is arranged coaxially with the chuck 4 (front-to-back horizontal direction). A shaping component 6 is positioned on the output shaft of the motor 5. The shaping component 6 includes a mounting plate 61 positioned on the output shaft of the motor 5. A shaping roller 62 capable of rolling and pressing to shape the inner wall of the aluminum tube end is rotatably mounted on the mounting plate 61. A grinding block 65 capable of grinding the aluminum tube end is positioned on the mounting plate 61.

[0027] In use, the aluminum tube to be shaped is clamped and fixed by the chuck 4, with the tube end extending a short distance towards the shaping component 6. The motor 5 is started to drive the shaping component 6 to rotate (at a relatively low speed). The moving frame 2 is then slowly moved closer to the support frame 1 until the rotating shaping roller 62 contacts and presses against the inner wall of the aluminum tube end, rotating along with it. This achieves high efficiency and precision in shaping the cut end of the aluminum tube. As the moving frame 2 moves towards the support frame 1, the rotating grinding block 65 finally contacts and grinds the aluminum tube end (at this point, the shaping is basically complete, and the motor 5 speed can be increased to improve the grinding effect). The overall structure is simple, easy to use, and highly efficient in shaping and grinding aluminum tube ends, effectively ensuring the consistency of the quality of aluminum tube end processing.

[0028] The movable frame 2 is connected to several guide rods 3 that slide and insert with the support frame 1, and can be driven by a motor and a ball screw transmission structure. The guide rods 3 ensure that the movable frame 2 moves strictly along a predetermined linear trajectory relative to the support frame 1, preventing deviation or swaying during movement. This allows for more precise positioning of the motor 5 and shaping assembly 6 mounted on the movable frame 2 as they approach or move away from the aluminum tube, ensuring that the shaping roller 62 and grinding block 65 accurately act on the corresponding positions at the aluminum tube ends, improving the accuracy of shaping and grinding operations. The ball screw structure offers higher rigidity, load-bearing capacity, stable transmission, and high efficiency, reducing the adverse effects of vibration on the shaping effect.

[0029] The chuck 4 features a ring-shaped array of jaws 41, with rubber protective pads covering the inner clamping surfaces of the jaws 41. This ring-shaped array of jaws 41 applies clamping force to the aluminum tube simultaneously from different directions, resulting in more uniform force distribution on the aluminum tube within the chuck 4. This effectively prevents the aluminum tube from shaking or shifting during processing, ensuring stability during shaping and polishing, and guaranteeing improved processing accuracy. The relatively soft rubber protective pads on the inner clamping surfaces of the jaws 41 prevent direct rigid contact between the jaws 41 and the aluminum tube surface, preventing scratches and indentations and ensuring the integrity of the aluminum tube surface. This design is particularly suitable for aluminum tube processing scenarios requiring high surface quality.

[0030] Among them, such as Figure 2 As shown, the support frame 1 has a through hole 12 corresponding to the chuck 4, and a first chamfer 13 is provided on the side of the through hole 12 away from the movable frame 2. The through hole 12 corresponds to the chuck 4, and the first chamfer 13 on the edge of the through hole 12 effectively guides the aluminum tube when it is inserted and clamped, and avoids the aluminum tube end from directly colliding and scratching with the edge of the through hole 12, thus reducing the risk of damage to the aluminum tube end during installation.

[0031] Several forming rollers 62 are arranged in a ring-shaped, evenly spaced configuration relative to the output shaft of motor 5. This ring-shaped distribution of forming rollers 62 allows for simultaneous application of force from different directions during the rolling and extrusion shaping of the inner wall of the aluminum tube end. This results in more even extrusion force across the inner wall of the aluminum tube end, preventing over- or under-shaping in certain areas and significantly improving the uniformity of the overall shaping effect. This ensures consistent dimensional accuracy and surface flatness throughout the end. Compared to a single forming roller 62, the simultaneous operation of multiple forming rollers 62 results in a larger contact area with the inner wall of the aluminum tube end per unit time, providing a wider shaping range and significantly improving the shaping efficiency of the aluminum tube cutting end, meeting the processing speed requirements of large-scale production. The evenly distributed ring-shaped forming rollers 62 also balance the forces applied to the inner wall of the aluminum tube during operation, reducing vibration and misalignment caused by uneven force distribution.

[0032] Preferably, the number of forming rollers 62 is even. This achieves symmetry in the extrusion and forming of the aluminum tube. The reaction forces of the aluminum tube on the forming assembly 6 cancel each other out.

[0033] The shaping roller 62 has a second chamfer 66 on its outer edge near the chuck 4. This second chamfer 66 gives the end of the shaping roller 62 a tapered shape. When the shaping assembly 6 is brought close to the aluminum tube port, this chamfer acts as a guide, making it easier and smoother for the shaping roller 62 to be inserted into the aluminum tube port, improving operational convenience. Furthermore, the second chamfer 66 avoids hard contact and scratching with the inner wall of the aluminum tube, resulting in a gentler contact and protecting the inner wall of the aluminum tube. In the initial stage of shaping, the second chamfer 66 gradually increases the contact area between the shaping roller 62 and the inner wall of the aluminum tube. This means that the extrusion pressure can be applied more evenly to the inner wall of the aluminum tube port, avoiding abnormal deformation of the aluminum tube port caused by excessive localized force. This provides a more stable and reliable starting condition for subsequent shaping operations, helping to improve the uniformity and accuracy of the overall shaping effect.

[0034] The device includes several grinding blocks 65, each corresponding to a shaping roller 62. When grinding the end of the aluminum tube, the tube end can be ground simultaneously from multiple angles, ensuring consistent grinding force across all parts of the tube end. This results in a more uniform grinding effect, effectively preventing over- or under-grinding areas and improving the overall surface quality of the tube end. After the shaping roller 62 completes the rolling and extrusion shaping of the inner wall of the aluminum tube end, the corresponding grinding blocks 65 immediately grind the shaped area. This ensures a smoother transition between the shaping and grinding processes, eliminating the need for additional adjustments to the equipment position or the aluminum tube's orientation, thus improving processing efficiency. The multiple grinding blocks share the grinding workload, resulting in relatively uniform and minimal wear on each block, which helps extend the overall service life of the grinding blocks 65.

[0035] The grinding block 65 has a third chamfer 67 on its left and right edges near the chuck 4. When the grinding block 65 is used for grinding near the aluminum tube end, the third chamfer 67 prevents sharp contact between the edge of the grinding block 65 and the surface of the aluminum tube end, making the contact between the grinding block 65 and the aluminum tube smoother and effectively preventing accidental scratches to the aluminum tube. The third chamfer 67 also helps to smoothly transition the grinding force, avoiding uneven grinding caused by sudden changes in grinding force, thus resulting in a more uniform and smoother surface on the aluminum tube end after grinding, improving the grinding quality.

[0036] The mounting plate 61 is connected to the center of the output shaft end of the motor 5 via mounting bolts 63. The mounting bolts 63 provide strong clamping force, firmly fixing the mounting plate 61 to the center of the output shaft end of the motor 5, preventing loosening or displacement of the mounting plate 61. This ensures that components such as the forming roller 62 and the grinding block 65 can accurately operate on the aluminum tube end, guaranteeing the stability and consistency of the forming and grinding effects. Using mounting bolts 63 for connection simplifies equipment assembly, debugging, and subsequent maintenance, improving maintainability and reducing maintenance costs.

[0037] Furthermore, the off-center position of the motor 5 output shaft end is positioned and mounted to the mounting plate 61 via a locating pin 64. The locating pin 64 at the off-center position effectively prevents the mounting plate from rotating or shifting slightly due to centrifugal force, vibration, or other external forces when the motor 5 rotates at high speed, ensuring the positional accuracy of the shaping component 6 during operation and improving the stability of the entire shaping mechanism. The locating pin 64 provides precise positioning during installation and also shares some of the mechanical stress transmitted from the mounting plate 61 to the motor output shaft.

[0038] In this aluminum tube cutting end shaping mechanism, the aluminum tube to be shaped is clamped and fixed by the chuck 4, with the tube end extending a short distance towards the shaping component 6. The motor 5 is started, driving the shaping component 6 to rotate (at a relatively low speed). The moving frame 2 is then slowly moved towards the support frame 1 until the rotating shaping roller 62 contacts and presses against the inner wall of the aluminum tube end, rotating along with it. This achieves high efficiency and precision in shaping the aluminum tube cutting end. As the moving frame 2 moves towards the support frame 1, the final rotating grinding block 65 contacts and grinds the aluminum tube end (at this point, the shaping is basically complete; the motor 5 speed can be increased to improve the grinding effect). The overall structure is simple, easy to use, and highly efficient in shaping and grinding aluminum tube ends, effectively ensuring the consistency of the quality of aluminum tube end processing.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
