They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 2As shown, an aluminum tube support ring mechanism includes a support head stamping assembly 2 and two support ring mold seats 3 symmetrically distributed vertically. The support head stamping assembly 2 is located on one side of the two support ring mold seats 3. The support head stamping assembly includes a support head mold seat 201 and a support head 202. The support head mold seat 201 is connected to the support head 202, and a first protruding ring groove 4 is provided at the connection. Each support ring mold seat has a positioning groove 5 on its surface. The two positioning grooves cooperate with each other to form a positioning cavity for clamping the aluminum tube. The positioning cavity and the support head are located on the same central axis. The support ring mold seat includes a fixed seat 3011 and a movable seat 3012. The movable seat is slidably connected to the fixed seat along the axial direction of the positioning cavity. The positioning groove includes a fixed groove 501, a movable groove 502, and a second convex ring groove 503. The fixed groove 501 is mounted on a fixed base 3011, and the movable groove 502 and the second convex ring groove 503 are mounted on a movable base 3012. One end of the movable groove mates with the support head, and the other end connects to the second convex ring groove. The second convex ring groove is located between the movable groove and the fixed groove. The inner diameters of the fixed groove and the movable groove are the same and smaller than the inner diameters of the first convex ring groove and the second convex ring groove. The inner diameters of the fixed groove and the movable groove match the outer diameter of the aluminum tube. The inner diameters of the first convex ring groove and the second convex ring groove are the same and match the outer diameter of the annular protrusion on the aluminum tube. When performing ring-forming on aluminum tube 1, aluminum tube 1 is first placed in the positioning cavity between two ring-forming mold seats. The two ring-forming mold seats clamp and fix aluminum tube 1. Then, the ring-forming head stamping assembly 2 moves quickly to one side of the aluminum tube, and the ring head is inserted into the aluminum tube. At the same time, the end of the aluminum tube is embedded in the first convex ring groove 4. The ring-forming head mold seat 201 applies pressure to the movable seat 3012 and pushes it to move towards the fixed seat 3011. As a result, the aluminum tube at the first convex ring groove 4 and the second convex ring groove 503 undergoes local deformation under axial force, forming an outward bulge and forming a ring-shaped protrusion, realizing the one-time forming of the two ring protrusions.

[0030] Combination Figure 2 and Figure 3 As shown, one end of the fixed seat has an L-shaped slot 6 for accommodating the movable seat, and one end of the movable seat is connected to a sliding rod 7. The sliding rod is slidably connected to a stepped sliding hole 8 on the fixed seat. The end of the sliding rod passes through the stepped sliding hole and is threadedly connected to a nut 9. A spring 10 is fitted on the sliding rod and is located inside the stepped sliding hole. After the ring upsetting is completed, the movable seat quickly resets under the action of the spring, facilitating the next ring upsetting process. The nut can limit the reset of the movable seat and the sliding rod. To facilitate the disassembly, assembly, and maintenance of the movable seat and the sliding rod, the movable seat has a first mounting hole 11 for assembling the sliding rod. One side of the first mounting hole has a first locking hole 12, and a first locking rod 13 for fixing the sliding rod is threaded into the first locking hole. By turning the first locking rod, the sliding rod can be effectively locked and fixed, which is simple and convenient to operate.

[0031] Combination Figure 2 and Figure 6As shown, the pier head mold base is provided with a second mounting hole 14 for assembling the pier head. The inner diameter of the second mounting hole is smaller than the inner diameter of the first convex ring groove, and a second locking hole 15 is provided on one side. The second locking hole is internally threaded with a second locking rod 16 for fixing the pier head, which facilitates the disassembly, assembly and maintenance of the pier head.

[0032] like Figure 4 As shown, an aluminum tube pressing and ringing device includes an aluminum tube pressing and ringing mechanism, a first support 17, a second support 18, a clamping cylinder 19, a stamping cylinder 20, and a worktable 21. The first and second supports are mounted on the worktable. The aluminum tube pressing and ringing mechanism includes a pressing head stamping assembly 2, an upper pressing ring mold seat 301, and a lower pressing ring mold seat 302. The clamping cylinder is located on the upper part of the first support, and its output shaft is connected to the upper pressing ring mold seat. The lower pressing ring mold seat is located on the lower part of the first support. The stamping cylinder is located on the second support, and its output shaft is connected to the pressing head stamping assembly. The clamping cylinder 19 drives the upper pressing ring mold seat to move downward, effectively clamping and fixing the aluminum tube to be processed. The stamping cylinder 20 drives the pressing head stamping assembly to move rapidly toward the aluminum tube, completing the pressing and ringing process on the aluminum tube.

[0033] Combination Figure 4 and Figure 5 As shown, a lifting block 22 is provided between the upper piercing ring mold seat and the clamping cylinder. The lifting block has an upper groove 23 that is connected to the upper piercing ring mold seat. The upper piercing ring mold seat is embedded in the upper groove. An upper locking rod 24 for fixing the upper piercing ring mold seat is threaded to one side of the lifting block. A lower groove 25 that is connected to the lower piercing ring mold seat is provided on the first support. The lower piercing ring mold seat is embedded in the lower groove. A lower locking rod 26 for fixing the lower piercing ring mold seat is threaded to one side of the first support. The above structural design facilitates the quick disassembly and replacement of the two piercing ring mold seats, so as to realize the piercing ring processing of aluminum tubes of different specifications.

[0034] like Figure 4 As shown, a movable seat 27 is provided between the stamping cylinder and the head stamping assembly. The movable seat is slidably connected to the slide rail 28 on the workbench, which can effectively improve the motion stability during the head stamping process. The movable seat is provided with a third mounting hole 29 for assembling the head stamping assembly. A third locking rod 30 for fixing the head stamping assembly is threaded into the third mounting hole, which facilitates the disassembly, replacement and maintenance of the head stamping assembly.

[0035] The working principle of this utility model is as follows:

[0036] like Figures 2 to 6As shown, the clamping cylinder 19 drives the upper pier ring mold seat 301 to move downward and cooperate with the lower pier ring mold seat 302 to clamp and fix the aluminum tube 1 located in its positioning cavity. The stamping cylinder 20 drives the pier head stamping assembly 2 to move rapidly toward the aluminum tube 1. The end of the aluminum tube 1 is embedded in the first convex ring groove 4 of the pier head mold seat 201. The pier head mold seat 201 squeezes the movable seat 3012 and drives it to slide toward the fixed seat 3011. Since the aluminum tube 1 is fixed as a whole, it undergoes local deformation under axial force, forming outward bulges and annular protrusions at the first convex ring groove 4 and the second convex ring groove 503, respectively, thereby realizing the one-time forming of two annular protrusions.

[0037] The specific operating steps for using this invention to perform ring-forming treatment on aluminum tubes are as follows:

[0038] S1, place the aluminum tube 1 to be processed into the lower support ring mold seat 302, with one end of it located outside the movable groove 502;

[0039] S2, the clamping cylinder 19 works, driving the lifting block 22 and the upper pier ring mold seat 301 to descend and clamp and fix the aluminum tube 1;

[0040] S3, the stamping cylinder 20 operates, driving the moving seat 27 and the stamping assembly 2 to move rapidly towards the aluminum tube 1 to complete the ring forming process. The resulting aluminum tube 1 contains two annular protrusions 101 (e.g., Figure 1 (As shown).

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
