Description

Technical Field

[0001] The present invention relates to the technical field of automatic cutting equipment, and in particular to an intelligent pipe cutting equipment for aluminum material processing. Background Art

[0002] During aluminum processing, formed aluminum tubes often need to be cut to the required lengths. A circular saw is a commonly used cutting machine, offering advantages such as high cutting efficiency and high section accuracy. However, due to its structural characteristics and operating principles, it is only suitable for aluminum tubes with smaller diameters. For larger diameters, a band saw, with its low linear speed and relatively poor cutting performance, must be used.

[0003] The utility model patent with announcement number CN217290661U discloses a rotary disc saw circular pipe cutting machine, in which a rotating disc is mounted on a fixed frame, and a pair of cutting mechanisms are mounted on the disc. Thus, the cutting mechanisms can rotate around the pipe and cut the pipe wall, making it suitable for cutting large-diameter pipes. However, this technology also has significant disadvantages. Generally speaking, the power unit, reduction device, feed mechanism, and power distribution line are necessary components of the cutting mechanism. It is difficult to install these components as a whole on the disc and ensure that they can rotate with the disc through conventional installation methods. It is difficult to implement and has high manufacturing costs. During operation, the disc needs to drive the above-mentioned redundant structure to rotate, which consumes a lot of energy and significantly increases operating costs. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides an intelligent pipe cutting equipment for aluminum processing, which uses a circular saw blade as the cutting component. Through sophisticated structural design, the circular saw blade can cut the pipe wall by rotating around the aluminum pipe, which not only retains the working advantages of the circular saw machine, but also significantly improves the diameter range of applicable aluminum pipes.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: An intelligent tube cutting device for aluminum processing, comprising a cutting device, characterized in that the cutting device comprises: The machine body is provided with a lifting support and a driving mechanism for driving the lifting support to move up and down, wherein a support ring, a first driving device and a second driving device are fixed on the lifting support; A first rotating ring is rotatably connected to the supporting ring with the center lines of the first rotating ring coinciding with the center lines of the first rotating ring. The first rotating ring is axially provided with an eccentric shaft hole. The first rotating ring is driven by a first driving device to rotate. A main shaft is rotatably connected to the eccentric shaft hole, one end of the main shaft extends to the outside of the first rotating ring and is mounted with a circular saw blade, and a driven gear is fixed to the main shaft; a second rotating ring, which is rotatably connected to the first rotating ring and whose center lines coincide with each other, and is provided with a gear ring portion, which meshes with the driven gear; and the second rotating ring is driven by a second driving device to rotate; The control system controls the working states of the driving mechanism, the first driving device and the second driving device to adjust and control the height of the lifting support, the rotation angle of the first rotating ring and the rotation speed of the second rotating ring.

[0006] In a preferred embodiment, the first rotating ring is provided with a first rotating connection part, a second rotating connection part and an inner lining part which are distributed in sequence along the axial direction, the eccentric shaft hole is opened on the second rotating connection part, the inner lining part is provided with a gear housing, and the support ring is sleeved on the first rotating connection part; the second rotating ring is provided with a third rotating connection part, and the third rotating connection part is sleeved on the second rotating connection part; the driven gear is located inside the gear housing, and the inner lining part is located on the inner side of the gear ring part; the end of the inner lining part away from the second rotating connection part is fixedly connected to a retaining ring, and the retaining ring is provided with a gear cover and a through hole.

[0007] In a preferred embodiment, a first transmission coupling portion is provided on the outer side of the first rotating ring. The first transmission coupling portion establishes a transmission connection with a first driving device based on a gear transmission mechanism or a belt transmission mechanism. The first driving device is a motor device with a self-locking function.

[0008] In a preferred embodiment, a first transmission coupling portion is provided on the outer side of the first rotating ring, and teeth are provided on the outer side of the first transmission coupling portion to form a worm gear. A worm engaged with the first transmission coupling portion is rotatably connected to the lifting support, and the first driving device can drive the worm gear to rotate.

[0009] In a preferred embodiment, a second transmission coupling portion is provided on the outer side of the second rotating ring. The second transmission coupling portion establishes a transmission connection with a second driving device based on a gear transmission mechanism or a belt transmission mechanism. The second driving device is a motor device.

[0010] In a preferred embodiment, the intelligent tube cutting equipment for aluminum processing further includes a feeding device, which includes: beam frame; A plurality of supporting wheels are rotatably connected to the beam frame, and the supporting wheels are evenly spaced along the length direction of the beam frame; the upper ends of the supporting wheels protrude from the upper side of the beam frame; Several self-positioning and limiting mechanisms, each of which includes two oblique arms located on both sides of the axial direction of the supporting wheel; the lower end of the oblique arm is rotatably connected to the beam frame, and a positioning roller is rotatably connected to the oblique arm; the two positioning rollers are symmetrically distributed in an inverted eight shape, and the two oblique arms are transmission-connected to a third drive device.

[0011] Compared with the prior art, the intelligent tube cutting equipment for aluminum processing in the present invention has the following beneficial technical effects: 1. The aluminum tube is cut based on a high-speed rotating circular saw blade, which retains the technical advantages of high efficiency and high precision inherent in traditional circular saws. At the same time, because the circular saw blade can rotate around the aluminum tube, it can cut large-diameter aluminum tubes, significantly improving the diameter range of applicable aluminum tubes. Compared with the previous method of cutting large-diameter aluminum tubes by rotating the aluminum tube, the working method of this intelligent tube cutting equipment is more energy-saving, efficient, economical and practical.

[0012] 2. Based on the sophisticated transmission structure design, the circular saw blade can rotate around the aluminum tube, and the second drive device that provides power to the circular saw blade does not need to be moved. On the one hand, unnecessary energy loss caused by the movement of the second drive device is avoided. On the other hand, because the second drive device does not need to be moved, the power supply line and protective mechanism and other auxiliary components can be set in a conventional way, which is easier to implement. Based on this design feature, the device also has a compact and simple structure.

[0013] 3. Based on the scientific and reasonable structural design, the second rotating ring can rotate infinitely, so the position of the circular saw blade can be adjusted more flexibly. When cutting large-diameter aluminum tubes, it can fully ensure that the cutting seam is completely closed, improve the cutting effect, and effectively reduce the idle stroke of the circular saw blade, saving energy consumption.

[0014] 4. The intelligent pipe cutting equipment has a simple and compact structure, high component utilization, easy implementation and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See Figure 1-Figure 7 As shown, the intelligent pipe cutting equipment for aluminum processing disclosed in the present invention includes a cutting device, which includes a body 1, a first rotating ring 9, a main shaft 7, a second rotating ring 6 and a control system; The machine body 1 is provided with a lifting support 3 and a driving mechanism 2. The lifting support 3 is driven by the driving mechanism 2 to move up and down. In practice, the driving mechanism 2 is a commonly used linear driving mechanism such as a pneumatic cylinder, an oil cylinder, an electric cylinder, or a linear motor. A support ring 5, a first driving device 4, and a second driving device 10 are fixed to the lifting support 3. The main body of the support ring 5 is annular, with its centerline in the horizontal direction. The main body of the first rotating ring 9 is annular, and the first rotating ring 9 is rotatably connected to the support ring 5, and the center lines of the first rotating ring 9 and the support ring 5 coincide with each other; an eccentric shaft hole 11 is axially provided on the wall of the first rotating ring 9; the first driving device 4 is in transmission connection with the first rotating ring 9, thereby being able to drive the first rotating ring 9 to rotate; The main shaft 7 is rotatably connected to the eccentric shaft hole 11. The main shaft 7 and the eccentric shaft hole 11 can rotate relative to each other but cannot move relative to each other in the axial direction. One end of the main shaft 7 extends to the outside of the first rotating ring 9 and is fixed with a circular saw blade 8. A driven gear 13 is fixed to the main shaft 7, and the center lines of the driven gear 13 and the driven gear 13 coincide with each other. The main body of the second rotating ring 6 is annular, and the second rotating ring 6 is rotatably connected to the first rotating ring 9 with their center lines coinciding. The second rotating ring 6 is provided with a gear ring portion 602, which is uniformly distributed with teeth and meshes with the driven gear 13. The second driving device 10 is in transmission connection with the second rotating ring 6, thereby being able to drive the second rotating ring 6 to rotate. The control system is used to control the working states of the driving mechanism 2 , the first driving device 4 and the second driving device 10 , so as to adjust and control the height of the lifting support 3 , the rotation angle of the first rotating ring 9 and the rotation speed of the second rotating ring 6 .

[0031] The usage and working principle of this intelligent pipe cutting equipment are as follows: like Figure 1 、 Figure 2 As shown, in the initial state of the device, the center lines of the main shaft 7 and the first rotating ring 9 are located in the same vertical plane. In other words, the main shaft 7 is located directly above or below the center line of the first rotating ring 9. During the cutting operation, the position of the aluminum tube to be cut is adjusted so that the aluminum tube passes through the inside of the first rotating ring 9, and the center lines of the aluminum tube and the first rotating ring 9 are ensured to be in the same vertical plane. When the diameter of the aluminum tube to be cut is small, that is, the circular saw blade 8 can meet the cutting requirements by moving in a straight line; under the control of the controller, the second driving device 10 drives the second rotating ring 6 to rotate, and the first rotating ring 9 remains stationary. The second rotating ring 6 will drive the main shaft 7 to rotate via the driven gear 13, causing the circular saw blade 8 to rotate at high speed; at the same time, the lifting support 3 drives the circular saw blade 8 to move in the vertical direction, thereby cutting the entire aluminum tube. After the cutting is completed, the equipment returns to the initial state. The above working principle and cutting effect are substantially the same as those of the existing circular saw machine. like Figure 8 、 Figure 9 As shown, when the diameter of the aluminum tube to be cut is large, that is, the circular saw blade 8 cannot meet the cutting requirements by moving in a straight line; under the control of the controller, the second driving device 10 drives the second rotating ring 6 to rotate, and the second rotating ring 6 drives the main shaft 7 to rotate through the driven gear 13, so that the circular saw blade 8 rotates at high speed; at the same time, the lifting support 3 drives the circular saw blade 8 to move in the vertical direction until the center lines of the aluminum tube and the second rotating ring 6 tend to coincide, during which the circular saw blade 8 will cut into the tube wall of the aluminum tube; thereafter, the first driving device 4 drives the first rotating ring 9 to rotate, and the circular saw blade 8 will rotate with the first rotating ring 9, that is, the circular saw blade 8 will rotate around the aluminum tube to gradually cut different positions of the tube wall until the cut is closed, thereby cutting the entire aluminum tube, and the equipment is reset to its initial state after the cutting is completed. In the above process, although the first rotating ring 9 and the second rotating ring 6 rotate at the same time, the conventional speed adjustment is used to keep the first rotating ring 9 and the second rotating ring 6 at an appropriate speed difference, thereby ensuring that the circular saw blade 8 rotates at a predetermined speed. When the aluminum tube is cut in this way, the inherent advantages of high efficiency and high precision of the traditional circular saw are retained. At the same time, because the circular saw blade 8 can rotate around the aluminum tube, the diameter range of the applicable aluminum tube is significantly improved.

[0032] In the further optimization design of this intelligent pipe cutting equipment: See Figure 3-Figure 7As shown, the first rotating ring 9 is provided with a first rotating connection part 903, a second rotating connection part 902 and an inner lining part 901 distributed in sequence along the axial direction, the eccentric shaft hole 11 is opened on the second rotating connection part 902, and the inner lining part 901 is provided with a gear housing 14 for accommodating the driven gear 13, and the end of the gear housing 14 away from the second rotating connection part 902 and the side away from the center of the first rotating ring 9 are both open structures; the support ring 5 is sleeved on the first rotating connection part 903, and the two are rotated together, thereby realizing the rotation connection between the support ring 5 and the first rotating ring 9; the second rotating ring 6 is provided with a third rotating connection part 603, and the third rotating connection part 604 is provided on the second rotating ring 6. 03 is sleeved on the second rotating connection part 902, and the two are rotated to cooperate, thereby realizing the rotational connection between the first rotating ring 9 and the second rotating ring 6; the driven gear 13 is located inside the gear housing 14, and the inner lining part 901 of the first rotating ring 9 is located on the inner side of the gear ring part 602 of the second rotating ring 6; the end of the inner lining part 901 away from the second rotating connection part 902 is fixedly connected to the retaining ring 12 via a bolt or other connecting member, and the retaining ring 12 is provided with a gear cover 121 for blocking the end of the gear housing 14 away from the second rotating connection part 902, and the retaining ring 12 is provided with a through hole 122 for the main shaft 7 to pass through, and the retaining ring 12 provides a limiting function for the driven gear 13 and the second rotating ring 6; The technical advantages of this structural design are: On the one hand, the first rotating ring 9, the second rotating ring 6, the main shaft 7 and the driven gear 13 can be conveniently assembled. During the specific assembly process, the corresponding end of the main shaft 7 is first inserted into the eccentric shaft hole 11 and the driven gear 13 is located in the gear housing 14. The third rotating connection portion 603 of the second rotating ring 6 is sleeved on the second rotating connection portion 902 of the first rotating ring 9, and the toothed ring portion 602 of the second rotating ring 6 is ensured to be meshed with the driven gear 13. Finally, the retaining ring 12 is fixedly connected to the inner lining portion 901, and the main shaft 7 is ensured to pass through the through hole 122 of the retaining ring 12 so as to install the circular saw blade 8. On the other hand, the fitting clearance between the first rotating ring 9 and the second rotating ring 6 is prevented from being exposed to the inside, and at the same time, the eccentric shaft hole 11, the main shaft 7, the driven gear 13 and the gear ring part 602 are fitted in a relatively closed space; thereby, the debris and dust generated during the cutting operation can be effectively prevented from entering the fitting clearance of the above components, thereby significantly improving the working stability and service life of the intelligent pipe cutting equipment.

[0033] Furthermore, if Figure 5 、 Figure 7As shown, a first transmission coupling portion 904 is provided on the outer side of the first rotating ring 9, and the first transmission coupling portion 904 is in transmission connection with the first drive device 4; specifically, the first drive device 4 may adopt a motor device, and the first transmission coupling portion 904 may establish a transmission connection with the first drive device 4 based on a gear transmission mechanism by setting teeth, or may establish a transmission connection with the first drive device 4 based on a belt transmission mechanism by setting belt grooves. Taking into account that during the operation of the present intelligent pipe cutting equipment, the second rotating ring 6 drives the main shaft 7 to rotate, which will generate a force on the first rotating ring 9. In order to avoid unexpected rotation of the first rotating ring 9, a corresponding locking mechanism should be provided for the first rotating ring 9 to ensure the controllability of the rotation angle of the first rotating ring 9. Therefore, when the first transmission coupling portion 904 is in transmission connection with the first drive device 4 based on a gear transmission mechanism or a belt mechanism, the first drive device 4 should have a locking function, such as selecting a motor device with a self-locking function; In another embodiment, a first transmission coupling portion 904 is provided on the outer side of the first rotating ring 9, and the first transmission coupling portion 904 is transmission-connected to the first drive device 4. For cost considerations, the first drive device 4 uses an ordinary motor device without a self-locking function, and the first transmission coupling portion 904 and the first drive device 4 use a transmission mechanism with a self-locking function to establish a transmission connection to achieve a locking effect on the first rotating ring 9. For example, teeth are provided on the outer side of the first transmission coupling portion 904 to form a worm gear. A worm that meshes with the first transmission coupling portion 904 is rotatably connected to the lifting support 3. The first drive device 4 is transmission-connected to the worm gear and can drive the worm gear to rotate. Thus, the worm gear and the first transmission coupling portion 904 form a worm gear mechanism with a self-locking function, which can drive the first rotating ring 9 to rotate and provide a locking effect for the first rotating ring 9 to prevent the first rotating ring 9 from rotating unexpectedly.

[0034] Further, see Figure 6 、 Figure 7 As shown, a second transmission coupling portion 601 is provided on the outer side of the second rotating ring 6, and the first transmission coupling portion 904 is transmission-connected to the second drive device 10; specifically, the second drive device 10 can adopt a motor device, and the second transmission coupling portion 601 can establish a transmission connection with the second drive device 10 based on a gear transmission mechanism by setting teeth, and can also establish a transmission connection with the second drive device 10 based on a belt transmission mechanism by setting a belt groove.

[0035] See Figure 10 、 Figure 11As shown, the intelligent tube cutting equipment for aluminum processing disclosed in the present invention also includes a feeding device for feeding the aluminum tube to be cut into the first rotating ring 9 and ensuring that the center lines of the aluminum tube and the first rotating ring 9 are located in the same vertical plane; the feeding device includes a beam frame 16, a plurality of supporting wheels 20 and a plurality of self-positioning limit mechanisms; The supporting wheels 20 are rotatably connected to the beam 16 via a horizontal axle 19. The supporting wheels 20 are evenly spaced along the length of the beam 16. The upper ends of the supporting wheels 20 protrude from the upper side of the beam 16 to provide support for the aluminum tube. Each self-positioning and limiting mechanism includes two oblique arms 17 symmetrically distributed on either side of the axis of the supporting wheel 20; the lower end of the oblique arm 17 is rotatably connected to the beam 16, and a rotatable positioning roller 18 is installed on the oblique arm 17; the two positioning rollers 18 are symmetrically distributed on both sides of the supporting wheel 20 in an inverted eight-shaped pattern, that is, the spacing increases from bottom to top; the two oblique arms 17 are transmission-connected to a third drive device 21, the working state of which is controlled by the control system, and can drive the two oblique arms 17 to swing, so as to synchronously adjust the inclination angles of the two positioning rollers 18. During the swinging process of the two oblique arms 17, the two positioning rollers 18 always remain symmetrical; Based on the above structure adopted by the feeding device, when the aluminum tube to be cut is placed above the supporting wheel 20, the supporting wheel 20 can provide support for the aluminum tube, and the positioning roller 18 can provide a limiting effect on the aluminum tube from both sides. Since the positioning roller 18 is in an inclined state, the aluminum tube will automatically adjust to the position directly above the supporting wheel 20 based on its own gravity, thereby achieving the purpose of self-positioning; in actual use, the feeding device is placed on one side of the axial direction of the first rotating ring 9. After the aluminum tube is placed on the feeding device, it can be ensured that the center lines of the aluminum tube and the first rotating ring 9 are located in the same vertical plane. When the aluminum tube is subjected to axial force, the supporting wheel 20 and the positioning roller 18 can rotate, so that the aluminum tube moves smoothly along the axial direction to achieve feeding.

[0036] Since the inclination angle of the inclined arm 17 and the positioning roller 18 can be adjusted, the positional relationship between the two positioning rollers 18 and the supporting wheel 20 can be adjusted to suit aluminum tubes of different diameters; specifically, when the diameter of the aluminum tube is larger, the angle between the two inclined arms 17 is increased accordingly to ensure that when the supporting wheel 20 supports the lower side of the aluminum tube, the two positioning rollers 18 can abut against both sides of the aluminum tube to achieve the expected limiting effect; on the contrary, when the diameter of the aluminum tube is smaller, the angle between the two inclined arms 17 can be reduced accordingly; when using the present feeding device to feed aluminum tubes of different diameters, the vertical plane in which the center line of the aluminum tube is located is constant. Therefore, when facing aluminum tubes of different diameters, it can be ensured that the center lines of the aluminum tube and the first rotating ring 9 are located in the same vertical plane to meet the aforementioned cutting operation requirements.

[0037] like Figure 10 、 Figure 11As shown, further, the lower end of the inclined arm 17 is fixedly connected to a crank arm 23, and the two crank arms 23 in the same self-positioning limit mechanism are respectively connected to a third drive device 21 through a connecting rod mechanism 22. The third drive device 21 is a commonly used linear drive mechanism such as a pneumatic cylinder, an oil cylinder, an electric cylinder and a linear motor.

[0038] like Figure 12 As shown, in another embodiment, the feeding device includes a fourth driving device 15, and the fourth driving device 15 is connected to the supporting wheel 20 in a transmission manner, and can drive the supporting wheel 20 to rotate. Thus, the feeding device can drive the aluminum tube to move axially by rotating the supporting wheel 20 to achieve feeding; further, a transmission belt 24 is installed on the supporting wheel 20, and the transmission belt 24 can establish a transmission connection between all the supporting wheels 20 and can rotate synchronously. At the same time, the supporting wheel 20 supports the aluminum tube through the transmission belt 24, which can increase the force of the supporting wheel 20 on the aluminum tube, so as to drive the aluminum tube to move axially more stably.

[0039] See Figure 13 As shown, the intelligent tube cutting equipment for aluminum processing disclosed in the present invention also includes a discharge device 25; the discharge device 25 has the same structure as the feeding device, and the two are distributed on opposite sides of the cutting device; since the discharge device 25 has the same structure as the feeding device and has the same function, during the cutting process, the discharge device 25 can support the aluminum tube at the other end of the cut. After the cutting is completed, the cut aluminum tube can be axially moved by the discharge device 25 to achieve discharge.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
