Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting processing, and particularly relates to an automatic control device for pipe cutting and deburring. Background Art

[0002] During industrial processing and production, it is often necessary to perform fixed-length cutting on various metal tubular components, such as aluminum pipes and aluminum profiles. The traditional cutting method is to use a pipe cutting machine to cut metal tubular components according to the required length. However, there are still some deficiencies in the traditional pipe cutting machine during use. For example, there will be burrs at the end cut of the pipe fitting after cutting, and workers are required to unload the materials, then transport and load them onto the deburring machine. The processes are numerous and the production efficiency is low.

[0003] Currently, there is a disclosed deburring pipe cutting machine and pipe cutting method (CN115922353A). When in use, the pipe fitting to be cut is placed in the pipe placing area, the first motor is started, and the moving seat is moved backward. The cutting blade can cut the pipe fitting in the pipe placing area. Then the first motor is stopped, the position of the cut pipe fitting is adjusted, and then the second motor is started, and the moving seat is moved forward. Then the grinding wheel can grind the cut. There is no need to additionally transport the pipe fitting to the deburring machine. However, the equipment with deburring function in the prior art still has the following deficiencies:

[0004] Pipes with different pipe diameters cannot be cut sufficiently, especially when encountering pipes with larger pipe diameters.

[0005] 2. When grinding the cut of the pipe fittings on both sides, since the grinding wheel only contacts the flat part of the cut during the grinding process, although this contact method can remove most of the burrs on the plane, for the burrs that do not directly lie on the cut plane but extend into the pipe or towards the edge, or burrs in hidden positions inside or at the edge of the pipe fitting, the grinding wheel may not be able to directly reach them. Therefore, these burrs are not easily removed, and the burr removal is insufficient, which easily affects the quality of the pipe fitting. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic control device for pipe cutting and deburring. Through the coordinated processing of a moving mechanism, a first rotating mechanism, a first limiting and guiding mechanism, a cutting mechanism, a second limiting and guiding mechanism, a second rotating mechanism, and a grinding mechanism, the problem that pipes with different pipe diameters cannot be cut sufficiently is solved; by the inclined butt joint of the grinding mechanism with the outer edge and inner edge of the pipe fitting cut, the problem that the burrs extending into the pipe or towards the edge, or burrs in hidden positions inside or at the edge of the pipe fitting are not easily removed is solved.

Furthermore, the rotating pipe fitting generates friction with the grinding block to remove the burrs extending or hidden at the outer edge and the inner edge. At the same time, the removed burrs will be discharged from the discharge port. For pipe fittings with different wall thicknesses, the outer edge and the inner edge of the cut are also in inclined contact with the external grinding surface and the internal grinding surface to fully remove the burrs.

Detailed implementation mode

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Embodiment 1

[0045] In this embodiment, Figures 1 - 15As shown, an automatic control device for pipe cutting and deburring is disclosed, which includes a workbench 1 located on a processing production line, a moving mechanism 2 is arranged on one side of the workbench 1, and is used for automatically conveying pipe fittings in fixed lengths, and a first rotating mechanism 3, a first limiting guide mechanism 4, a cutting mechanism 5, a second limiting guide mechanism 6 and a second rotating mechanism 7 are arranged in sequence on the workbench 1 along the processing direction (i.e., the conveying direction of the moving mechanism 2), wherein the first rotating mechanism 3 is arranged close to the moving mechanism 2, and a grinding mechanism 8 is also arranged on the workbench 1 at a position corresponding to the cutting mechanism 5, and is used for fully grinding and removing burrs from the cut ends of the pipe fittings after cutting.

[0046] The pipe fittings are automatically cut and deburred by the cooperation of the moving mechanism 2, the first rotating mechanism 3, the first limiting guide mechanism 4, the cutting mechanism 5, the second limiting guide mechanism 6, the second rotating mechanism 7 and the grinding mechanism 8. 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.

[0047] like Figure 1 , Figure 2 and Figure 8 As shown, the workbench 1 comprises a frame 10 , a panel 12 is arranged on the top of the frame 10 , and the panel 12 is used to receive and install the various mechanisms mentioned above, and an extension bracket 11 is arranged on one side of the frame 10 for receiving and installing the moving mechanism 2 .

[0048] 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.

[0049] Among them Figures 1 - 3 As shown, the above-mentioned moving mechanism 2 includes a mounting base 21 fixedly connected to the extension bracket 11, and slide rails 22 are symmetrically arranged on both sides of the top surface of the mounting base 21, and a moving base 25 is slidably arranged on the two slide rails 22, and a two-way telescopic cylinder 26 is installed on the top of the moving base 25, and the telescopic rods on both sides of the two-way telescopic cylinder 26 are symmetrically connected to the clamping seats, and the two clamping seats are both installed with clamping blocks 27, and mounting blocks are symmetrically arranged at both ends of one side of the mounting base 21, and screws 23 are rotatably installed on the two mounting blocks, and one end of the screw 23 is connected to the output shaft of the moving motor 24 fixed on one side of the mounting base 21, wherein the moving base 25 is threadedly connected to the screw 23 near one end of the screw 23.

[0050] The moving motor 24 drives the screw 23 to rotate. The screw 23 drives the moving base 25 to move horizontally. And the two-way telescopic cylinder 26 drives the clamping blocks 27 on both sides to clamp the pipe fittings. Then, in cooperation with the movement of the moving base 25, the clamping and conveying of the pipe fittings are realized. Among them, a limiting block is also provided on the mounting base plate 21 to prevent the moving base 25 from moving excessively and interfering with other structures. A moving chain can also be provided on the mounting base plate 21 to ensure the stability of the movement.

[0051] And the above-mentioned clamping block 27 is made of an elastic material, such as rubber, etc. It can elastically clamp the pipe fittings, avoid damaging the surface of the clamped part of the pipe fittings, and at the same time can achieve full, stable and adaptable clamping of pipe fittings with different diameters, avoiding the need to replace different clamping structures for the processing of pipe fittings with different diameters and improving the efficiency of the entire processing. Further, it should be noted that the clamping block 27 can also be provided with a groove in the middle (as Figure 3 shown), which improves the ease of deformation in the middle of the clamping block 27, makes the effective clamping surface between the clamping block 27 and the pipe fitting larger after clamping, and ensures the stability of the clamping.

[0052] Furthermore, in order to make the equipment in this embodiment adaptable to the processing of pipe fittings with different diameters and perform sufficient cutting, in this embodiment, the first rotating mechanism 3 and the second rotating mechanism 7 are provided to clamp and rotate the pipe fittings. In cooperation with the cutting mechanism 5, sufficient cutting is realized. By using the rotary cutting of the pipe fittings, the cutting mechanism 5 can smoothly cut the pipe fittings with a larger diameter.

[0053] Among them, as Figure 4 and Figure 5 shown, the above-mentioned first rotating mechanism 3 includes a mounting bracket 31 connected to the extension bracket 11. A positioning cylinder 32 is installed on the top of the mounting bracket 31. The telescopic rod of the positioning cylinder 32 passes through the mounting bracket 31 and is connected with an adjusting cross-seat 33. And the adjusting cross-seat 33 is slidably arranged on the mounting bracket 31 and can slide up and down along the mounting bracket 31. A fixed base 34 is connected to the bottom surface of the adjusting cross-seat 33. An arc groove larger than a semi-circle is opened on the fixed base 34. A rotating base 35 is rotatably arranged in the arc groove. The side of the rotating base 35 away from the moving mechanism 2 is connected with a mounting panel 36 by bolts. A clamping groove is opened in the middle of the mounting panel 36. A plurality of sliding pressure strips 37 are symmetrically installed on both sides of the clamping groove of the mounting panel 36. Two sliding pressure strips 37 on each side are a group. A sliding groove is opened between the opposite sides of a group of sliding pressure strips 37. A clamping jaw 39 is slidably arranged in cooperation between the two sliding grooves. And a clamping cylinder 38 is connected to the tail of the clamping jaw 39. The clamping cylinder 38 is fixed on the mounting panel 36 and pushes the clamping jaw 39 to slide between a group of sliding pressure strips 37. The opposite two groups of clamping jaws 39 move inward to realize the clamping of the pipe fittings. Among them, the clamping surface of the clamping jaw 39 is provided with an inward concave arc surface to increase the adaptability to pipe fittings with different diameters.

[0054] Further, one end of the horizontal base 33 is connected with an installation shell 310 through a connecting rod. A rotating motor 311 is arranged inside the installation shell 310. The output shaft of the rotating motor 311 is connected with a driving gear 312. A tooth groove is formed on the axial surface of the rotating base 35. The driving gear 312 is meshed with the tooth groove. The rotating base 35 is driven to rotate by the rotating motor 311, so as to drive the pipe fitting to rotate.

[0055] Furthermore, the above-mentioned second rotating mechanism 7 has the same structure as the first rotating mechanism 3. The difference is that the first rotating mechanism 3 is installed on the extension bracket 11, while the second rotating mechanism 7 is installed on the panel 12, and the second rotating mechanism 7 is close to the output end of the pipe fitting.

[0056] By adopting the first rotating mechanism 3 and the second rotating mechanism 7, the two ends of the pipe fitting are synchronously rotated, and then cooperate with the cutting mechanism 5 for cutting, so that the pipe fitting can be stably cut.

[0057] Furthermore, in order to ensure the stability of the pipe fitting during the rotary cutting process and avoid the deformation of the pipe fitting caused by uneven stress at the cut end of the pipe fitting, in this embodiment, the first limit guiding mechanism 4 and the second limit guiding mechanism 6 are arranged to limit and support the pipe fitting at both ends of the cut and conduct rotary guiding, so as to provide sufficient supporting force for the pipe fitting and ensure the stability of the cutting process and avoid bending deformation.

[0058] As Figure 6 and Figure 7 shown, the above-mentioned first limit guiding mechanism 4 includes a first rotary guiding component 41 installed on the panel 12 and a first limit component 42 located outside the first rotary guiding component 41. The first rotary guiding component 41 includes an installation base 411. The installation base 411 is fixedly connected to the panel 12. A sliding cavity is formed in the middle of the installation base 411. Chute grooves are symmetrically formed at both ends of the sliding cavity. A connecting seat 412 is arranged in the middle of the sliding cavity. Offset platforms 414 are symmetrically and slidably installed on both sides of the connecting seat 412. Both ends of the offset platforms 414 are slidably matched with the chute grooves. An adjusting screw rod 413 is rotatably arranged on the connecting seat 412. The adjusting screw rod 413 is a bidirectional screw rod, and both ends of the bidirectional screw rod extend towards both ends of the connecting seat 412 and are threadedly connected with the corresponding offset platforms 414. One end of the adjusting screw rod 413 is connected with an adjusting handle for manually adjusting the distance between the two offset platforms 414. An installation platform 415 is arranged on each offset platform 414. A guiding cylinder 416 is rotatably arranged on the installation platform 415. The guiding cylinder 416 is arranged along the length direction of the pipe fitting. The two guiding cylinders 416 stably support the cutting end of the pipe fitting and guide the rotation of the pipe fitting, so as to ensure that the pipe fitting can rotate smoothly while having supporting force.

[0059] By rotating the adjusting screw rod 413, the guiding cylinders 416 on both sides are driven to move towards each other, so as to adjust the distance between the guiding cylinders 416 and adapt to the stable support of pipe fittings with different pipe diameters.

[0060] Further, the first limiting component 42 includes support columns 421 located at the four corners of the mounting base 411. Connecting plates are arranged at the tops of two support columns 421 on the same side in a matching manner. Rotating gears are rotatably arranged in the middle of the two connecting plates. An adjusting rod 422 is threadedly connected to the middle of the rotating gear (external threads are provided on the outer shaft surface of the adjusting rod 422, and internal threads are provided in the middle of the rotating gear, and the two cooperate to achieve up and down movement). The bottoms of the two adjusting rods 422 are connected to a moving substrate 424 in a matching manner, and the four sides of the moving substrate 424 are slidably connected to the four support columns 421. A rotating handle is installed at the top of the rotating gear on one side. The two rotating gears are driven by a transmission chain 423. A first limiting air cylinder 425 is arranged in the middle at the bottom of the moving substrate 424. The telescopic rod of the first limiting air cylinder 425 is connected to a mounting seat. A first limiting roller 426 is rotatably installed in the mounting seat. The axis of the first limiting roller 426 is parallel to the axis of the guiding cylinder 416. The pipe fitting is cut and limited by the cooperation of the first limiting roller 426 and the guiding cylinder 416, so as to avoid the bending deformation of the pipe fitting at the cut during cutting.

[0061] By rotating the rotating gear, the adjusting rods 422 on both sides are synchronously driven to move up and down, and then the moving substrate 424 is driven to move up and down, roughly adjusting the distance between the first limiting roller 426 and the guiding cylinder 416. Then, the distance between the first limiting roller 426 and the guiding cylinder 416 is accurately adjusted by the first limiting air cylinder 425, so as to achieve the stable limiting support and guiding of the pipe fitting.

[0062] As Figure 10 and Figure 11 shown, the above-mentioned second limiting and guiding mechanism 6 includes a transverse movement component 63 installed on the workbench 1. The transverse movement component 63 includes a transverse movement track 631 installed on the panel 12. Multiple groups of sliders 632 are arranged on the transverse movement track 631. The multiple groups of sliders 632 are connected to a transverse movement substrate 633 in a matching manner. A movement matching groove is opened on the panel 12 below the transverse movement substrate 633. A transverse movement air cylinder 634 is installed at the bottom of the panel 12. The telescopic rod of the transverse movement air cylinder 634 passes through the movement matching groove through a connecting plate and is connected to the bottom of the transverse movement substrate 633, so as to achieve the flexible sliding of the transverse movement air cylinder 634 driving the transverse movement substrate 633 on the transverse movement track 631.

[0063] Further, a second rotary guiding assembly 61 is arranged on the transverse moving substrate 633, and a second limiting assembly 62 is arranged outside the second rotary guiding assembly 61. The structure and operation mode of the second rotary guiding assembly 61 are the same as those of the first rotary guiding assembly 41. The second limiting assembly 62 includes a connecting frame 621 arranged on the transverse moving substrate 633. An installation transverse plate 622 is connected to the top of the connecting frame 621. A second limiting cylinder 623 is installed at the bottom of the installation transverse plate 622 close to one end of the first limiting guiding mechanism 4. The telescopic rod of the second limiting cylinder 623 is connected with an installation seat, and a second limiting roller 624 is installed in the installation seat. The axis of the second limiting roller 624 is also parallel to the axis of the guiding cylinder 416. The limiting support for the cutting end of the pipe fitting is realized through the cooperation of the second limiting roller 624 and the guiding cylinder 416.

[0064] In this embodiment, a cutting mechanism 5 with an adjustable cutting angle is also provided to adapt to the cutting of pipe fittings with different diameters. The cutting mechanism 5 cooperates with the above-mentioned first rotating mechanism 3, second rotating mechanism 7, first limiting guiding mechanism 4 and second limiting guiding mechanism 6 to realize the stable and efficient cutting of pipe fittings with different diameters.

[0065] As Figure 8 and Figure 9 shown, the above-mentioned cutting mechanism 5 includes two groups of fixed seats 51 installed on the panel 12. A deflection table 52 is rotatably connected between the two groups of fixed seats 51 through a rotating shaft. A cutting motor 53 is arranged on one side of the deflection table 52, and a cutting installation seat 54 is arranged on the other side. A cutting shaft is rotatably arranged in the cutting installation seat 54. One end of the cutting shaft is connected to the output shaft of the cutting motor 53 through a chain to realize power transmission. The other end of the cutting shaft is connected with a cutting blade 55 to realize the cutting of the pipe fitting. An avoidance groove is formed in the panel 12 at the position below the deflection table 52. An adjusting cylinder 56 is rotatably arranged on the frame 10. The telescopic rod of the adjusting cylinder 56 passes through the avoidance groove and is rotatably connected to the bottom of the deflection table 52. The deflection angle of the deflection table 52 is adjusted by the telescopic movement of the adjusting cylinder 56, so as to change the cutting angle and adapt to the cutting of pipe fittings with different diameters.

[0066] As Figures 12 - 14 shown, in this embodiment, a grinding mechanism 8 is further arranged to synchronously grind and remove burrs from the cut ends of the two cut pipe fittings. At the same time, burrs at the cut of the pipe fitting are fully removed by setting an insertable docking grinding block 84, including burrs extending or hidden at the outer edge and inner edge.

[0067] The grinding mechanism 8 includes a support platform 81 arranged on the panel 12. A rotating motor 82 is installed on the support platform 81. The output shaft of the rotating motor 82 is connected with a rotating cross bar 83, and a grinding block 84 is installed at the head of the rotating cross bar 83.

[0068] And specifically as Figure 13As shown in the figure, an installation groove 831 is formed in the rotating cross bar 83. One end of the grinding block 84 is connected with a connecting rod 85. The connecting rod 85 is inserted into the installation groove 831. A connecting shaft 86 is arranged at one end of the installation groove 831. The connecting shaft 86 penetrates through the connecting rod 85. Springs (not shown in the figure) are arranged on the connecting shaft 86 on both sides of the connecting rod 85. Further, a push rod 611 is arranged on the second rotating guide assembly 61. The position of the grinding block 84 can be flexibly adjusted by the cooperation of the push rod 611 and the springs to butt the cut ends of the two pipe fittings.

[0069] Further, as Figure 14 shown, the above-mentioned grinding block 84 includes a grinding block body 841. Docking grooves 842 are symmetrically formed on both sides of the grinding block body 841. The outer side surface of the docking groove 842 is an outwardly inclined external grinding surface 843, and the inner side surface of the docking groove 842 is an inwardly inclined internal grinding surface 844. The further removal of burrs on the outer edge and inner edge is realized by the cooperation of the externally inclined external grinding surface 843 and the internally inclined internal grinding surface 844. At the same time, for the cut ends of pipe fittings with different wall thicknesses, the extended or hidden burrs can also be adaptively ground off. And in order to avoid the accumulation of burrs ground off during the grinding process and affect the grinding, a plurality of groups of discharge ports 845 are symmetrically formed on both sides of the grinding block body 841. Each group of discharge ports 845 communicates with the bottom of the docking groove 842, so that the burrs after grinding are discharged along the discharge ports 845, avoiding the accumulation of burrs in the docking groove 842 and affecting the grinding.

[0070] Further, for pipe fittings with different pipe diameters, the grinding block 84 needs to be replaced correspondingly. The grinding block 84 used for different pipe diameters only changes the position and size of the docking groove 842, and other structures remain unchanged.

[0071] By butting the cut end of the pipe fitting in the docking groove 842, the outer edge and inner edge of the cut end are in inclined contact with the external grinding surface 843 and the internal grinding surface 844. Then, the rotating pipe fitting generates friction with the grinding block 84, removing the extended or hidden burrs on the outer edge and inner edge. At the same time, the removed burrs will be discharged from the discharge ports 845. For pipe fittings with different wall thicknesses, the outer edge and inner edge of the cut end are also in inclined contact with the external grinding surface 843 and the internal grinding surface 844. The difference is that the contact positions are different, and the burrs can be further removed. Embodiment 2

[0072] This embodiment is the specific usage method of Embodiment 1, including the following steps:

[0073] Step 1. Preparation stage: According to the pipe diameter of the pipe fittings to be cut with a fixed length, rotate the adjusting screws 413 in the first limit guiding mechanism 4 and the second limit guiding mechanism 6 to adjust the distance between the corresponding two groups of guiding cylinders 416 respectively, so that they can be adapted for support. Synchronously start the positioning cylinders 32 in the first rotating mechanism 3 and the second rotating mechanism 7 to adjust the positions of the rotating bases 35 respectively, so that the axes of the two groups of rotating bases 35 are collinear, and the axes of the two groups of rotating bases 35

[0074] are respectively collinear with the circular axes formed by the two groups of guiding cylinders 416 on the corresponding side.

[0075] Step 2. Pipe fitting transportation: Place the pipe fittings to be cut between the two groups of guiding cylinders 416 of the first limit guiding mechanism 4. Start the first limit cylinder 425 to drive the first limit roller 426 to descend, and squeeze and limit the pipe fittings. Then start the double-acting telescopic cylinder 26 to drive the clamping block 27 to clamp the pipe fittings. Then the first limit cylinder 425 drives the first limit roller 426 to rise to release the pipe fittings. 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 transport the pipe fittings; at the initial stage, move to one end of the pipe fitting to be flush with the cutting blade 55, and then transport according to the fixed-length cutting distance. It should be noted that when the moving distance at one time is insufficient, multiple moves can be used to achieve fixed-length transportation.

[0076] Step 3. Rotary cutting: After the transportation is in place, the first limit cylinder 425 drives the first limit roller 426 to descend and the second limit cylinder 623 drives the second limit roller 624 to descend to squeeze and limit the pipe fittings. Then the clamping cylinder 38 pushes the jaws 39 to clamp the pipe fittings inward (the first rotating mechanism 3 and the second rotating mechanism 7 clamp synchronously). Start the rotating motor 311 to drive the driving gear 312 to rotate, and the driving gear 312 drives the rotating base 35 to rotate, thereby driving the pipe fittings to rotate. Start the cutting motor 53 to drive the cutting blade 55 to rotate, and synchronously start the adjusting cylinder 56 to adjust the angle of the cutting blade 55 for cutting;

[0077] Step 4. Deburring: After cutting, start the adjusting cylinder 56 to drive the cutting blade 55 away from the pipe fitting. Then start the clamping cylinder 38 of the second rotating mechanism 7 to drive the clamping jaws 39 to release the pipe fitting. Then start the transverse moving cylinder 634 to drive the transverse moving substrate 633 to move towards the second rotating mechanism 7, expanding the distance between the pipe fittings at both ends. Then start the rotating motor 82 to drive the rotating cross bar 83 to deflect by 90 degrees, so that the grinding block 84 corresponds to the height position of the pipe fitting cut. Then start the transverse moving cylinder 634 to drive the transverse moving substrate 633 to move towards the cutting mechanism 5. At the same time, the push rod 611 squeezes the connecting rod 85 to drive the grinding block 84 to move, so that the cuts of the pipe fittings at both ends are both butted into the docking grooves 842. Then start the clamping cylinder 38 of the second rotating mechanism 7 to drive the clamping jaws 39 to clamp the pipe fitting, and synchronously start the two groups of rotating motors 311 to drive the rotating bases 35 to rotate synchronously, thereby driving the pipe fitting to rotate for deburring. After grinding, the second rotating mechanism 7 releases the pipe fitting, and the transverse moving cylinder 634 drives the transverse moving substrate 633 to move towards the second rotating mechanism 7 to convey the pipe fitting after cutting and deburring. At the same time, the grinding block 84 resets, and the rotating motor 82 drives the grinding block 84 to deflect reversely by 90 degrees to return to the initial position, waiting for the next processing.

[0078] In this embodiment, through the precise conveying of the moving mechanism 2, the dimensional accuracy of the pipe fitting after cutting is ensured. The pipe fitting is driven to rotate synchronously by the first rotating mechanism 3 and the second rotating mechanism 7, and with the limiting and guiding of the first limiting and guiding mechanism 4 and the second limiting and guiding mechanism 6, the pipe fitting is cut evenly and stably during the cutting process, avoiding the pipe fitting being completely deformed due to the force at the cutting position, which affects the cutting quality. And the adjustability of the distance between the guide cylinders 416 in the first limiting and guiding mechanism 4 and the adjustability of the first limiting roller 426 or the second limiting roller 624 further enable this device to be applicable to the processing of pipe fittings with different pipe diameters.

[0079] Furthermore, in this embodiment, by the transverse moving assembly 63 driving the hind legs of the pipe fitting after cutting to expand the distance between the pipe fittings on both sides, the grinding mechanism 8 is further enabled to dock between the pipe fittings on both sides. Through the flexible adjustment of the position of the grinding block 84, the cuts of the pipe fittings at both ends can be inserted into the grinding block 84 to achieve sufficient grinding and remove the burrs extending or hidden on the outer edge and inner edge. Embodiment 3

[0080] Since the lengths of the pipe fittings to be cut are different, when encountering a longer pipe fitting, directly putting the pipe fitting in will cause the external pipe fitting to be unstable without support, affecting the entire cutting. Therefore, on the basis of Embodiment 1, this embodiment is provided with a feeding mechanism 9, which is arranged on one side close to the moving mechanism 2, and as Figures 16 - 18As 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.
