Description

Technical Field

[0002] In the process of industrial processing and production, it is often necessary to cut various metal tubular components, such as aluminum tubes and aluminum profiles, to a fixed length. The traditional cutting method is to use a tube cutting machine to cut the metal tubular components according to the required length. However, the traditional tube cutting machine still has some shortcomings during use. For example, after the tube is cut, there will be burrs on the end of the pipe. Workers are required to unload the materials, and then transport and load them to the deburring machine. There are many processes and the production efficiency is low.

[0003] At present, the prior art discloses a deburring pipe cutting machine and a pipe cutting method (CN115922353A). When in use, the pipe to be cut is placed in the pipe placing area, the first motor is started, and the movable seat is moved backward, and the cutting blade can cut the pipe on the pipe placing area, and then the first motor is stopped, the position of the cut pipe is adjusted, and then the second motor is started and the movable seat is moved forward, and the grinding wheel can grind the cut, without the need to carry the pipe to the deburring machine. However, the deburring equipment in the prior art still has the following deficiencies: It is not possible to fully cut pipes of different diameters, especially those with larger diameters. 2. When grinding the cuts on both sides of the pipe fittings, since the grinding wheel only contacts the flat part of the cut during the grinding process, this contact method can remove most of the burrs on the plane, but for the burrs that are not directly located on the cut plane but extend to the inside or edge of the pipe fitting or are located in hidden positions inside or on the edge of the pipe fitting, the grinding wheel may not be able to directly reach them. Therefore, these burrs are not easy to remove, and the burr removal is insufficient, which can easily affect the quality of the pipe fittings. Summary of the invention

The above mechanisms are interconnected and cooperated to form a processing whole, so that the pipe fittings can be processed in sequence and in an orderly manner, thereby improving the processing efficiency and quality, reducing manual operations, and saving labor costs.

[0024] In order to enable automatic conveyance of pipes during processing and ensure the accuracy of the conveying position, this embodiment installs a moving mechanism 2 on the extension bracket 11 to automatically convey the pipes and sets the conveying position according to requirements to ensure cutting accuracy.

A limit block is also arranged on the installation base plate 21, and the limit block is used to prevent the mobile base 25 from moving excessively and interfering with other structures; a mobile chain can also be arranged on the installation base plate 21 to ensure the stability of movement.

[0027] Furthermore, the clamping block 27 is made of an elastic material, such as rubber, which can elastically clamp the pipe to avoid damage to the surface of the pipe clamping part. At the same time, it can achieve a fully stable and adaptive clamping of pipes of different diameters, avoiding the need to replace different clamping structures for processing pipes of different diameters, thereby improving the efficiency of the entire processing. It should be further noted that the clamping block 27 can also be configured with a central slot (such as Figure 3 As shown in the figure), the deformation ease of the middle part of the clamping block 27 is improved, so that the effective clamping surface of the clamping block 27 and the pipe fitting is larger after clamping, thereby ensuring the stability of clamping.

At the same time, the extended or hidden burrs can be adaptively ground off for the pipe cuttings with different pipe wall thicknesses, and in order to avoid the accumulation of burrs polished off during the grinding process and the influence on the grinding, a plurality of groups of discharge ports 845 are symmetrically opened on both sides of the grinding block body 841, and each group of discharge ports 845 is connected to the bottom of the docking groove 842, so that the burrs after grinding are discharged along the discharge port 845, and the accumulation of burrs in the docking groove 842 is avoided, which affects the grinding.

[0046] Furthermore, for pipes with different diameters, the grinding blocks 84 need to be replaced accordingly. The grinding blocks 84 used for different pipe diameters only change the position and size of the docking groove 842, and other structures remain unchanged.

[0047] By docking the pipe cut in the docking groove 842, the outer edge and inner edge of the cut are made to contact with the outer polishing surface 843 and the inner polishing surface 844 at an angle, and then the rotating pipe and the polishing block 84 generate friction, and the burrs extending or hidden on the outer edge and the inner edge are removed. At the same time, the removed burrs will be discharged from the discharge port 845. For pipes with different wall thicknesses, the outer edge and inner edge of the cut are also made to contact with the outer polishing surface 843 and the inner polishing surface 844 at an angle. The difference is that the contact positions are different, and the burrs can be further removed. Embodiment 2

[0048] This embodiment is a specific method of using the first embodiment, and includes the following steps: Step 1, preparation stage: according to the diameter of the pipe fitting to be cut to a fixed length, the adjusting screw 413 in the first limiting guide mechanism 4 and the second limiting guide mechanism 6 is rotated to adjust the spacing between the two corresponding guide cylinders 416 so that they can adapt to the support, and the adjusting cylinder 32 in the first rotating mechanism 3 and the second rotating mechanism 7 is synchronously started to adjust the position of the rotating base 35 so that the axes of the two rotating bases 35 are collinear and the axes of the two rotating bases 35 are aligned. They are collinear with the circular axes formed by the two groups of guide cylinders 416 on the corresponding sides.

[0049] Step 2, pipe conveying: put the pipe to be cut between the two groups of guide cylinders 416 of the first limiting guide mechanism 4, start the limiting cylinder 425, drive the limiting roller 426 to descend, squeeze and limit the pipe, then start the two-way telescopic cylinder 26 to drive the clamping block 27 to clamp the pipe, then the limiting cylinder 425 drives the limiting roller 426 to rise, release the pipe, and at the same time start the moving motor 24 to drive the screw 23 to rotate, and the screw 23 drives the moving base 25 to move to convey the pipe; in the initial stage, move until one end of the pipe is flush with the cutting blade 55, and then convey it according to the fixed-length cutting distance. It should be explained that when the moving distance is insufficient at one time, multiple moves can be used to achieve fixed-length conveying.

[0050] Step 3, rotary cutting: after being transported to the right place, the limiting cylinder 1 425 drives the limiting roller 1 426 to descend, and the limiting cylinder 2 623 drives the limiting roller 2 624 to descend, so as to squeeze and limit the pipe fitting, and then the clamping cylinder 38 pushes the clamping claw 39 to clamp the pipe fitting inward (the first rotating mechanism 3 and the second rotating mechanism 7 clamp synchronously), and the rotating motor 311 is started to drive the driving gear 312 to rotate, and the driving gear 312 drives the rotating base 35 to rotate, and then drives the pipe fitting to rotate, and the cutting motor 53 is started to drive the cutting disc 55 to rotate, and the adjusting cylinder 56 is started synchronously to adjust the angle of the cutting disc 55 for cutting; Step 4, grinding burrs: After cutting, start the regulating cylinder 56 to drive the cutting blade 55 away from the pipe, then start the clamping cylinder 38 of the second rotating mechanism 7 to drive the clamping claw 39 to release the pipe, then start the traverse cylinder 634 to drive the traverse base plate 633 to move to one side of the second rotating mechanism 7 to expand the distance between the pipes at both ends, then start the rotating motor 82 to drive the rotating cross bar 83 to deflect 90 degrees so that the grinding block 84 corresponds to the height position of the pipe cut, then start the traverse cylinder 634 to drive the traverse base plate 633 to move toward the cutting mechanism 5, and at the same time, the push rod 611 squeezes the connecting rod 85 to drive the grinding block 84 Move so that the cuts of the pipe fittings at both ends are connected to the docking groove 842, and then start the clamping cylinder 38 of the second rotating mechanism 7 to drive the clamping claw 39 to clamp the pipe fitting, and synchronously start the two sets of rotating motors 311 to drive the rotating base 35 to rotate synchronously, and then drive the pipe fitting to rotate for grinding and deburring. After grinding, the second rotating mechanism 7 releases the pipe fitting, and the transverse cylinder 634 drives the transverse base plate 633 to move toward the second rotating mechanism 7 to transport the pipe fittings after cutting and deburring. At the same time, the grinding block 84 is reset, and the rotating motor 82 drives the grinding block 84 to deflect ninety degrees in the opposite direction and return to the initial position to wait for the next processing.

[0051] This embodiment ensures the dimensional accuracy of the pipe after cutting through the precise conveying of the moving mechanism 2, drives the pipe to rotate synchronously through the first rotating mechanism 3 and the second rotating mechanism 7, and cooperates with the limiting guidance of the first limiting guide mechanism 4 and the second limiting guide mechanism 6 to ensure that the pipe is cut evenly and stably during the cutting process, avoiding the pipe being completely deformed due to the force at the cutting point, which affects the cutting quality, and the adjustability of the spacing between the guide cylinders 416 in the first limiting guide mechanism 4 and the second limiting guide mechanism 6 and the adjustability of the limiting roller 1 426 or the limiting roller 2 624 further enable the present device to be applicable to the processing of pipes with different diameters; And the present embodiment further drives the rear legs of the cut pipe by the transverse movement assembly 63, thereby expanding the distance between the pipes on both sides, so that the grinding mechanism 8 can be docked between the pipes on both sides, and the position of the grinding block 84 can be flexibly adjusted so that the cuts of the pipes at both ends can be inserted into the grinding block 84 to achieve sufficient grinding, thereby removing the burrs extending or hidden on the outer and inner edges. Embodiment 3

[0052] Since the lengths of the pipes to be cut are different, when encountering a long pipe, directly placing the pipe will cause the external pipe to be unstable without support, affecting the entire cutting. Therefore, this embodiment is provided with a feeding mechanism 9 on the basis of the first embodiment. The feeding mechanism 9 is arranged on the side close to the moving mechanism 2, and Figure 16-Figure 18 As shown, the feeding mechanism 9 includes a material rack 91, on which a plurality of lifting mechanisms 92 are arranged at equal intervals, and the plurality of lifting mechanisms 92 are connected by transmission screws 93 to achieve synchronous lifting.

[0053] For longer pipe fittings, after the pipe fittings are placed in the first limiting guide mechanism 4, the outer part is placed in the loading mechanism 9 for support, wherein the lifting mechanism 92 includes a mounting cylinder 95 installed on the material rack 91, and a lifting rod 96 is slidably arranged inside the mounting cylinder 95, and the top of the lifting rod 96 is Y-shaped, and a transmission cylinder 97 is rotatably arranged on the Y-shaped inclined rod, and the axial surface of the lifting rod 96 is provided with a tooth groove, and a plurality of groups of transmission gears 94 are arranged at corresponding positions on the transmission screw 93, and the transmission gear 94 is meshed and connected with the lifting rod 96 at the corresponding position, and the transmission screw 93 is driven to synchronously drive the lifting rod 96 to move up and down to support pipes of different diameters, and the center of the circular trajectory tangent to the two transmission cylinders 97 is colinear with the axis of the rotating base 35, so as to realize stable transmission at the same height and stable conveying and support for longer pipe fittings.

[0054] Furthermore, an automatic unloading mechanism can be set on one side of the feeding mechanism 9, which can automatically release the pipe fittings to fall onto the feeding mechanism 9, and cooperate with the feeding mechanism 9 to realize automatic loading of the pipe fittings, further improving the automation level of the entire device, wherein no specific restrictions are made on the automatic unloading mechanism.

[0055] It should be noted that after the automatic loading, the transportation of the pipe requires the moving mechanism 2 to perform multiple reciprocating movements to achieve the initial state of cutting, that is, one end of the pipe is flush with the cutting blade 55.

[0056] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
