[0001] The utility model belongs to the technical field of aluminum pipe processing, and particularly relates to an aluminum pipe cutting and processing device. Background Art

[0002] All kinds of pipes are widely used in industry. Especially, the usage quantity of copper pipes, aluminum pipes, composite pipes, etc. in the thermophysical fields such as radiators and coolers is huge. However, for long aluminum pipes, in order to facilitate transportation and use, it is often necessary to carry out cutting operations on them. In the prior art, a pipe cutting machine applicable to metal pipe cutting is disclosed, and the literature number is: CN110000425B. This solution sets a cutting mechanism, and the cutting mechanism includes an annular blade and a power mechanism. The inner circle of the annular blade is provided with sawteeth, and the axis direction of the annular blade is horizontally arranged; the power mechanism is used to drive the annular blade to rotate around its axis. The sawteeth of the annular blade of this pipe cutting machine applicable to metal pipe cutting directly cut around the surface of the metal pipe, and the cutting efficiency is high;

[0003] However, in the above patent, the annular blade only approaches the axis of the metal pipe in the radial direction of the metal pipe and does not shift in the axial direction of the metal pipe, that is, it can only perform vertical cutting on the metal pipe and cannot perform inclined cutting. Then, when the metal pipe needs to be inclinedly cut, other cutting equipment needs to be replaced for operation, reducing the cutting efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an aluminum pipe cutting and processing device that can not only vertically cut an aluminum pipe but also inclinedly cut the aluminum pipe, and has a relatively high cutting efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: an aluminum pipe cutting and processing device, including a horizontally arranged bottom support table. The key structural points are that a positioning member is provided on the bottom support table, and the aluminum pipe can pass through the positioning member and be fixed by the positioning member. Two vertical plates are symmetrically arranged on both sides of the bottom support table, and an outer protection box is connected to the two vertical plates. A longitudinal support arm is arranged in the outer protection box. The upper end of the longitudinal support arm extends out of the outer protection box and is movably connected to the outer protection box. The lower end of the longitudinal support arm is connected with a longitudinal base plate and an electric push rod. A vertical moving block is connected to the longitudinal base plate. The power end of the electric push rod is connected to the vertical moving block and can drive the vertical moving block to move along the length direction of the longitudinal base plate. A cutting wheel is connected to the vertical moving block through a driving motor, and the driving motor can drive the cutting wheel to rotate; an angle adjustment plate is provided on the outer protection box. The longitudinal support arm is connected to the outer protection box through a shaft rod, and the longitudinal support arm can be turned around the shaft rod. A screw is screwed at the upper end of the longitudinal support arm, and the end of the screw can be screwed into the angle adjustment plate.

[0006] Furthermore, a limiting member is arranged between the two vertical plates. The limiting member includes a movable arm and a limiting clamping plate. One end of the movable arm is connected to the limiting clamping plate, and the other end horizontally penetrates through the vertical plate and is connected with an anti - detachment disc.

[0007] Further, a reset spring is sleeved on the movable arm. When the reset spring is compressed, a restoring force can be generated. The reset spring is located between the vertical plate and the limit clamping plate.

[0008] Further, a positioning groove is formed on the bottom support table. The positioning member is located in the positioning groove. The positioning member includes a rotating toothed ring. An annular groove is provided on the end face of the rotating toothed ring. A positioning ring is also connected to the rotating toothed ring.

[0009] Further, positioning rods are fixed on both side walls of the positioning groove. The rotating toothed ring is connected in the positioning groove. The end of the positioning rod is inserted into the annular groove. The aluminum tube can pass through the rotating toothed ring and the positioning ring and is fixed by the positioning ring.

[0010] Further, a rotating meshing part is provided above the rotating toothed ring. The rotating meshing part is connected to the outer protection box. The rotating meshing part includes a threaded rod. A flat rack is connected to the lower end of the threaded rod. The flat rack can move to contact and mesh with the rotating toothed ring.

[0011] Further, flat tooth grooves are respectively provided on the two vertical plates. The flat rack can gradually move into the flat tooth grooves. Both ends of the flat rack are located outside the two vertical plates.

[0012] Further, a semi-circular groove is provided on the bottom support table. The semi-circular groove is located below the cutting wheel. The cutting wheel can enter the semi-circular groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging the limiting member and the positioning member, the aluminum tube can be limited and fixed, avoiding the rolling or deviation of the aluminum tube during the movement and cutting processes, and improving the stability of the aluminum tube; at the same time, by meshing the flat rack with the rotating toothed ring, the aluminum tube in the rotating toothed ring can be driven to rotate, enabling the aluminum tube with a diameter larger than the cutting wheel to be completely cut. And by arranging the semi-circular groove, the direct contact between the cutting wheel and the bottom support table is avoided, resulting in the wear of the cutting wheel;

[0014] By fixedly connecting the longitudinal support arm with the outer protection box, the vertical cutting of the aluminum tube by the cutting wheel is realized. And by axially connecting the longitudinal support arm with the outer protection box, the cutting wheel can be tilted and flipped, enabling the inclined cutting of the aluminum tube by the cutting wheel. In this way, aluminum tubes with respective cutting angles can be processed according to the required cutting angles of the aluminum tubes.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

In the embodiments, the components of the embodiments of the present application usually described and shown in the accompanying drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application.

[0025] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0026] Refer to Figures 1 to 2 As shown, an aluminum tube cutting and processing device includes a horizontally arranged bottom support table 1. The lower surface of the bottom support table 1 is installed with support feet 2, and the support feet 2 can stably place the bottom support table 1. Vertical plates 3 are symmetrically arranged on both sides of the bottom support table 1. A limiting member 4 is arranged between the two vertical plates 3. The aluminum tube to be cut can be placed on the bottom support table 1, and the aluminum tube can pass through the limiting member 4, and the limiting member 4 can limit the aluminum tube to prevent the aluminum tube from rolling on the bottom support table 1. At the same time, a processing component 5 is also arranged on the two vertical plates 3. The aluminum tube passes through the limiting member 4 and the processing component 5 in sequence. A positioning member 6 is also arranged on the bottom support table 1. The positioning member 6 is located below the processing component 5, and the positioning member 6 can cooperate with the processing component 5 to drive the aluminum tube to rotate, so as to realize the cutting of the aluminum tube by the processing component 5.

[0027] The above-mentioned limiting member 4 is set to two groups, and the two groups of limiting members 4 are respectively connected to the vertical plates 3 on both sides. When the aluminum tube needs to be cut, the aluminum tube is placed on the bottom support table 1, and the aluminum tube will pass between the two groups of limiting members 4. The limiting members 4 can approach or move away from each other to adapt to aluminum tubes of different diameters and form a limit. Specifically:

[0028] Each limiting member 4 includes a movable arm 7 and a limiting clamping plate 8. One end of the movable arm 7 is connected to the limiting clamping plate 8, and the other end horizontally penetrates the vertical plate 3 and is connected with an anti-drop disk 9. The movable arm 7 can horizontally move in the vertical plate 3 along a direction perpendicular to the vertical plate 3. The limiting clamping plate 8 is located between the two vertical plates 3, and the anti-drop disk 9 is located outside the two vertical plates 3. A return spring 10 is sleeved on the movable arm 7. When the return spring 10 is compressed, it can generate a restoring force. The return spring 10 is located between the vertical plate 3 and the limiting clamping plate 8. Slide rods 11 are symmetrically arranged on the limiting clamping plate 8. The free ends of the slide rods 11 also horizontally penetrate the corresponding vertical plate 3, and the slide rods 11 can also horizontally move in the vertical plate 3. The arrangement of the slide rods 11 can make the limiting clamping plate 8 always maintain a vertical state during the horizontal movement, improving the stability of the limiting clamping plate 8 during the movement. At the same time, there is a slight gap between the limiting clamping plate 8 and the bottom support table 1 to avoid friction between the bottom support table 1 and the limiting clamping plate 8.

[0029] Refer to Figures 3 to 4As shown, a positioning member 6 is further provided on the bottom support table 1. A positioning groove 12 is formed on the upper surface of the bottom support table 1. The positioning member 6 is connected in the positioning groove 12. The positioning member 6 in the positioning groove 12 can be replaced according to the diameter of the aluminum tube. Positioning rods 13 are fixed on both side walls of the positioning groove 12. The positioning member 6 includes a rotating toothed ring 14. The aluminum tube can pass through the rotating toothed ring 14. Convex teeth are annularly and arrayedly distributed on the outer circumferential surface of the rotating toothed ring 14. Annular grooves 15 are provided on both end faces of the rotating toothed ring 14. The rotating toothed ring 14 is placed in the positioning groove 12. The end portions of the positioning rods 13 in the positioning groove 12 are inserted into the annular grooves 15 on the rotating toothed ring 14. In this way, the rotating toothed ring 14 can rotate in the positioning groove 12. At the same time, during the rotation process, the positioning rods 13 move in the annular grooves 15, preventing the rotating toothed ring 14 from separating from the positioning groove 12. A positioning ring 16 is further connected to the rotating toothed ring 14. The positioning ring 16 can be arranged on any one end face of the rotating toothed ring 14. The inner diameter of the positioning ring 16 is equal to the inner diameter of the rotating toothed ring 14. The outer diameter of the positioning ring 16 is smaller than the inner diameter of the annular groove 15. And the positioning ring 16 is located above the bottom support table 1. Tightening screws 17 are symmetrically arranged on the outer circumferential surface of the positioning ring 16. After the aluminum tube passes through the rotating toothed ring 14 and the positioning ring 16, the tightening screws 17 are tightened to fix the aluminum tube.

[0030] Refer to Figures 5 to 6 As shown, after the aluminum tube is fixed by the positioning member 6, the processing assembly 5 above will contact the rotating toothed ring 14 and drive the rotating toothed ring 14 to rotate, thereby driving the aluminum tube to rotate and enabling the processing assembly 5 to complete the cutting of the aluminum tube. At this time, a semi-circular groove 18 is formed on the bottom support table 1. The semi-circular groove 18 is located directly below the processing assembly 5. When the processing assembly 5 cuts the aluminum tube, the processing assembly 5 can enter the semi-circular groove 18 to ensure sufficient cutting of the aluminum tube and avoid the processing assembly 5 from contacting the bottom support table 1. The processing assembly 5 includes an outer protection box 19. The outer protection box 19 is rectangular and has an open lower end. The outer protection box 19 is located above the vertical plate 3 and both sides of the outer protection box 19 are connected to the corresponding vertical plate 3. A cutting part 20 and a rotating meshing part 21 are arranged in the outer protection box 19. The semi-circular groove 18 is located directly below the cutting part 20. The cutting part 20 can drive the rotating meshing part 21 to move vertically until both the cutting part 20 and the rotating meshing part 21 contact the aluminum tube below and drive the aluminum tube to complete cutting while rotating. Specifically:

[0031] The cutting part 20 includes a longitudinal support arm 22. The upper end of the longitudinal support arm 22 is fixed to the upper inner wall of the outer protection box 19, and the lower end is connected with a longitudinal base plate 23. A vertical moving block 24 is slidably connected to the longitudinal base plate 23, and the vertical moving block 24 can slide vertically along the longitudinal base plate 23. At this time, an electric push rod 25 is installed at the lower end of the longitudinal support arm 22. The power end of the electric push rod 25 is connected to the upper surface of the vertical moving block 24. The electric push rod 25 can drive the vertical moving block 24 to move vertically. At the same time, a driving motor 26 is installed on the vertical moving block 24, and the output end of the driving motor 26 is connected to the cutting wheel 27. When it is necessary to cut the aluminum pipe below, control the electric push rod 25 to drive the vertical moving block 24 to move downward until the cutting wheel 27 contacts the aluminum pipe, and then control the driving motor 26 to start working. Its output end can drive the cutting wheel 27 to rotate, so as to realize the cutting of the aluminum pipe;

[0032] The rotary meshing part 21 therein corresponds to the rotary tooth ring 14 on the bottom support table 1. The rotary meshing part 21 includes a threaded rod 28 and a flat rack 29. A rectangular groove 30 is provided on the upper surface of the flat rack 29. The lower end of the threaded rod 28 is slidably connected in the rectangular groove 30. The upper end of the threaded rod 28 extends vertically upward to penetrate the upper surface of the outer protection box 19 and is connected with a gripping disc 31. By rotating the gripping disc 31, the threaded rod 28 can move vertically while rotating, and drive the flat rack 29 to move vertically. However, the flat rack 29 does not rotate with the threaded rod 28. The flat rack 29 can move vertically to contact and mesh with the rotary tooth ring 14 below. At this time, flat tooth grooves 32 are respectively arranged on the two vertical plates 3. When the flat rack 29 approaches the rotary tooth ring 14, the flat rack 29 will gradually enter the flat tooth grooves 32 until the flat rack 29 meshes with the rotary tooth ring 14. During this process, both ends of the flat rack 29 are located outside the two vertical plates 3. Then when it is necessary to rotate the aluminum pipe, a horizontal thrust or pull force can be applied to the end of the flat rack 29 to drive the rotary tooth ring 14 to rotate, thereby realizing the rotation of the aluminum pipe.

[0033] When this device is in use, first place the aluminum tube on the bottom support table 1, pass the aluminum tube through the limiting member 4 and the positioning member 6 in sequence, so that the limiting member 4 and the positioning member 6 fix the aluminum tube, avoiding the rolling or displacement of the aluminum tube during the cutting process of the cutting tool, which affects the cutting effect. Subsequently, for aluminum tubes with a diameter smaller than that of the cutting wheel 27, directly control the electric push rod 25 to drive the cutting wheel 27 to move downward, and turn on the drive motor 26 to make the cutting wheel 27 rotate and complete the cutting of the aluminum tube. For aluminum tubes with a diameter larger than that of the cutting wheel 27, first rotate the gripping disc 31 to make the flat rack 29 move downward until it contacts and meshes with the rotating gear ring 14. Subsequently, control the electric push rod 25 to drive the cutting wheel 27 to move downward, and turn on the drive motor 26 to make the cutting wheel 27 rotate and cut the aluminum tube. Since the diameter of the aluminum tube is larger than that of the cutting wheel 27, the cutting wheel 27 cannot directly cut off the aluminum tube. At this time, apply a horizontal thrust or pull force to the end of the flat rack 29 to make the rotating gear ring 14 drive the aluminum tube to rotate until the cutting wheel 27 completely cuts off the aluminum tube. In this way, the vertical cutting of the aluminum tube can be realized.

[0034] Another embodiment of the present utility model is that the above structure can only perform vertical cutting on aluminum tubes. When the cutting requirement of the aluminum tube changes to inclined cutting, it can be realized through the following structure. Specifically:

[0035] Refer to Figure 7 As shown in the figure, on the basis of the above structure, the upper end of the longitudinal support arm 22 extends vertically upward and passes through the upper surface of the outer protection box 19. At the same time, the longitudinal support arm 22 is connected to the outer protection box 19 through a shaft rod, and the longitudinal support arm 22 can be turned around the shaft rod. At this time, a threaded hole is provided at the upper end of the longitudinal support arm 22, and a screw 33 is screwed into the threaded hole. At the same time, an angle adjustment plate 34 is provided on the upper surface of the outer protection box 19. The angle adjustment plate 34 is semi-circular and angle scale lines are provided on the plate surface of the angle adjustment plate 34. When the longitudinal support arm 22 is in a vertical state, the longitudinal support arm 22 is aligned with the center of the angle adjustment plate 34. When inclined cutting of the aluminum tube is required, a thrust can be applied to the upper end of the longitudinal support arm 22 to align the longitudinal support arm 22 with the required angle scale line, and then tighten the screw 33 so that the end of the screw 33 is aligned with the angle scale line on the angle adjustment plate 34 and screwed into the angle adjustment plate 34, so that the cutting wheel 27 indirectly connected to the lower end of the longitudinal support arm 22 can be turned from a vertical state to an inclined state at a specified angle, and the cutting wheel 27 can maintain this inclined angle to cut the aluminum tube. In this way, the inclined cutting of the aluminum tube at different angles can be realized.

[0036] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims described above.
