[0002] Aluminum tubes are tubular products made of aluminum alloy. Due to their light weight, corrosion resistance, and good thermal conductivity, they are widely used in various fields. Punching and threading are common processing methods for aluminum tubes. Punching involves creating through-holes of a certain size in the aluminum tube to facilitate the installation of accessories such as brackets and hooks. This allows the aluminum tube to be easily fixed in the desired position or connected to other structural components. Threading involves creating external threads on the end of the aluminum tube, allowing it to be connected to components with internal threads, such as nuts, thereby assembling pipelines or structures. These processing methods not only increase the flexibility of aluminum tubes but also enhance their functionality, making them more adaptable to various application scenarios.

DETAILED DESCRIPTION

[0018] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0019] An aluminum tube punching and threading machine, such as Figure 1-Figure 5 As shown, it includes a workbench 1, a support table 2, a first cylinder 3, a chamfering assembly 4, a slide rail 5, a threading assembly 6, a second cylinder 7, a support frame 8, an upper hopper 9 and a lower plate 17. The top of the workbench 1 is fixedly connected to the support table 2, the top of the support table 2 is fixedly connected to the first cylinder 3, the piston rod of the first cylinder 3 is installed with the chamfering assembly 4, the chamfering assembly 4 is provided with a motor and a chamfering tool, the motor and the chamfering tool are connected by a belt drive, the top of the workbench 1 is fixedly connected to the slide rail 5, the threading assembly 6 is slidably connected to the slide rail 5, and the threading assembly 6 is equipped with a motor and a threading tool, and the motor and the threading tool are connected by a belt drive. The left side of the slide rail 5 is fixedly connected to the second cylinder 7, and the threading assembly 6 is connected to the piston rod of the second cylinder 7. The rear side of the workbench 1 is fixedly connected to the support frame 8, and the top of the support frame 8 is fixedly connected to the upper hopper 9. The top of the workbench 1 is fixedly connected to the lower plate 17. The upper hopper 9 and the lower plate 17 are both inclined. The rear side of the upper hopper 9 and the rear side of the lower plate 17 are higher than the front side of the upper hopper 9 and the front side of the lower plate 17. A clamping mechanism is connected between the workbench 1 and the support frame 8.

[0020] When threading the aluminum tube, the aluminum tube is placed in the upper hopper 9, and the aluminum tube slides forward along the upper hopper 9, and then the aluminum tube is clamped by the clamping mechanism, and the threading assembly 6 is driven by the second cylinder 7 to move to the right and close to the aluminum tube, and then the aluminum tube is threaded by the threading assembly 6. After the threading process is completed, the threading assembly 6 is driven away from the aluminum tube by the second cylinder 7, and the clamping mechanism releases the aluminum tube, and the aluminum tube falls on the blanking plate 17 to complete the unloading, thereby completing the threading process of the aluminum tube. When it is necessary to punch the aluminum tube, only the threading tool in the threading assembly 6 needs to be replaced with a punching tool, and the above steps can be repeated. When it is necessary to chamfer the aluminum tube, the chamfering assembly 4 is driven downward by the first cylinder 3 so that the chamfering assembly 4 is close to the aluminum tube for chamfering. The aluminum tube is first placed in the upper hopper 9 for loading, which reduces the risk of manual loading of the aluminum tube.

[0021] like Figure 1 、 Figure 3 and Figure 4 As shown, the clamping mechanism includes a third cylinder 11, a first push plate 12, a mounting frame 18, a fourth cylinder 19, a limit plate 20 and a second push plate 21. The third cylinder 11 is fixedly connected to the left side of the support frame 8, and the first push plate 12 is fixedly connected to the piston rod of the third cylinder 11. A avoidance groove for the first push plate 12 to pass through is opened on the front side of the upper hopper 9. The top of the workbench 1 is fixedly connected to the mounting frame 18, and the fourth cylinder 19 is fixedly connected to the mounting frame 18. The piston rod of the fourth cylinder 19 passes through the mounting frame 18, and the second push plate 21 is fixedly connected to the piston rod of the fourth cylinder 19. The top of the mounting frame 18 is fixedly connected to the limit plate 20, and the second push plate 21 is slidably connected to the limit plate 20. When the aluminum tube falls out of the upper hopper 9, the fourth cylinder 19 first moves the second push plate 21 backward along the limit plate 20 so that the second push plate 21 is in close contact with the aluminum tube, and then the third cylinder 11 drives the first push plate 12 to move forward and in close contact with the aluminum tube. Under the joint extrusion of the first push plate 12 and the second push plate 21, the aluminum tube is moved to the same straight line of the threading assembly 6, and then the aluminum tube is threaded, punched or chamfered. There is no need to manually adjust the clamping force of the clamping mechanism, which improves the safety of the clamping mechanism.

[0022] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, it also includes a limiting frame 13, a fixing rod 14, a hinge block 15 and an elastic member 16. The front side of the guide plate 10 is fixedly connected to the limiting frame 13, and the front side of the limiting frame 13 is fixedly connected to the fixing rod 14. The left and right sides of the fixing rod 14 are rotatably connected to the hinge blocks 15. The length of the hinge block 15 above the limiting frame 13 is greater than the outer diameter of the aluminum tube. The left and right hinge blocks 15 are fixedly connected to the fixing rod 14 with elastic members 16. The elastic member 16 is set to a torsion spring. When the elastic member 16 is in a normal state, the hinge block is perpendicular to the ground. When the aluminum tube falls from the loading plate to the limit frame 13, the hinge block 15 will block the aluminum tube under the elastic force of the elastic member 16 to prevent the aluminum tube from falling out of the limit frame 13. When the clamping mechanism moves the aluminum tube out, the aluminum tube will squeeze the hinge block 15, causing the hinge block 15 to rotate and the elastic member 16 to be compressed. When the clamping mechanism moves the aluminum tube away from the hinge block 15, the elastic member 16 returns to its original state, causing the hinge block 15 to reset, thereby limiting the subsequent aluminum tubes and preventing the subsequent aluminum tubes from falling out and affecting the processing of the aluminum tubes.

[0023] like Figure 1 、 Figure 3 and Figure 4As shown, the sides of the first push plate 12 and the second push plate 21 that are close to each other are both curved, and the arc of each arc is less than 180 degrees, which can prevent the aluminum tube from being trapped on the first push plate 12 or the second push plate 21. After the aluminum tube is processed, the third cylinder 11 drives the first push plate 12 to move backward away from the aluminum tube. The aluminum tube is no longer clamped by the first push plate 12 and the second push plate 21, and then naturally falls from the second push plate 21 to the blanking plate, thus completing the unloading of the aluminum tube.

[0024] like Figure 3 and Figure 4 As shown, the feed hopper 9 further includes a guide plate 10, which is fixedly connected to the feed hopper 9. The guide plate 10 is parallel to the feed hopper 9, with the front side of the guide plate 10 extending out of the feed hopper 9 and extending vertically downward. When the aluminum tubes slide on the feed plate, the guide plate 10 ensures that only one aluminum tube falls at a time. During the processing of the aluminum tubes, subsequent aluminum tubes will remain in the space formed by the first push plate 12 and the guide plate 10, preventing multiple aluminum tubes from falling and interfering with the processing of the aluminum tubes.

[0025] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that various other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the invention should be limited only by the claims appended hereto.
