Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting, and specifically to a high-frequency pipe making machine for automatic production of carbon pipes. Background Art

[0002] The pipe making machine is mainly used for pipe production, and processes metal sheets into pipes after uncoiling, forming, welding, grinding, sizing, straightening, sizing, and cutting.

[0003] In the prior art, the Chinese invention patent with the publication number CN118455615B discloses a numerically controlled gantry pipe making machine with high safety. By limiting the two ends of the pipe, the phenomenon of warping at the outer end of the pipe during cutting is avoided. While the pipe loading is stable, the pipe cutting process is more stable, improving the pipe cutting quality of the pipe making machine.

[0004] Currently, after the carbon steel pipe is formed, it is cut by the cutting equipment at the tail of the pipe making machine. However, since the pipe is always in a conveying state, during cutting, the traditional cutting equipment is prone to positional deviation in the length direction of the pipe, which not only easily causes the blade to break, but also makes the cut of the pipe uneven, affecting the finished product quality. Therefore, the present invention proposes a high-frequency pipe making machine for automatic production of carbon pipes to solve the above problems. Summary of the Invention

Detailed implementation manners

[0033] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 11 , the present invention provides a technical solution:

[0035] Embodiment 1, a high-frequency pipe making machine for automatic production of carbon pipes, comprising: a workbench 1.

[0036] A mounting frame 2 is slidably mounted on the workbench 1. The mounting frame 2 can only slide along the length direction of the workbench 1. Two symmetrically distributed arc-shaped translation plates 3 are arranged on the upper part of the mounting frame 2, and a pipe body 8 is arranged between the two arc-shaped translation plates 3. The pipe body 8 is parallel to the length direction of the workbench 1. The pipe body 8 is conveyed by a conveying device on a pipe making machine in the prior art, such as Figure 1 As shown, the right end of the pipe body 8 is the part to be cut. The pipe body 8 moves horizontally from left to right. In addition, the two arc-shaped translation plates 3 are spliced into a circular ring and are concentric with the pipe body 8. The two arc-shaped translation plates 3 can move away from each other or approach each other. When approaching each other, they can be spliced into a circular ring;

[0037] Secondly, a first convex plate 31 is fixedly arranged on one side edge of the arc-shaped translation plate 3. An arc-shaped clamping plate 4 is arranged inside the first convex plate 31, and an elastic telescopic rod 41 is fixed between the two. The elastic telescopic rod 41 is a telescopic rod structure known in the prior art and has a built-in thrust spring. The elastic telescopic rod 41 always maintains an extended state. According to actual needs, hydraulic oil can also be filled inside the elastic telescopic rod 41 to achieve the effect of buffering and shock absorption. A plurality of elastic telescopic rods 41 are arranged and evenly distributed between the first convex plate 31 and the arc-shaped clamping plate 4. On the one hand, it avoids the rotation of the arc-shaped clamping plate 4, and on the other hand, it reduces the bearing capacity of a single elastic telescopic rod 41. The two arc-shaped clamping plates 4 clamp the pipe body 8 from both sides. In the initial state, the two arc-shaped translation plates 3 are in a state of moving away from each other. When the two arc-shaped translation plates 3 approach each other, the arc-shaped clamping plate 4 first fits the surface of the pipe body 8, and the two arc-shaped clamping plates 4 clamp the pipe body 8. At this time, the arc-shaped clamping plate 4 moves synchronously with the pipe body 8 under the action of friction. That is to say, the arc-shaped translation plate 3 and the mounting frame 2 can move synchronously with the pipe body 8;

[0038] Furthermore, an arc-shaped rotating plate 5 that fits with it is arranged inside the arc-shaped translation plate 3. The arc-shaped rotating plate 5 can only slide around the circumferential direction of the arc-shaped translation plate 3 inside the arc-shaped translation plate 3. An arc-shaped side plate 51 is fixed on one side surface of the arc-shaped rotating plate 5. The arc-shaped side plate 51 and the arc-shaped rotating plate 5 can slide synchronously. A cutting blade 7 is installed on the arc-shaped side plate 51, and the cutting blade 7 slides along the radial direction of the arc-shaped rotating plate 5. When the cutting blade 7 rotates, it can be used to cut the surface of the pipe body 8. When the arc-shaped rotating plate 5 rotates and slides around the center of the arc-shaped translation plate 3, it can drive the cutting blade 7 to move accordingly, forming as Figure 8The cutting path shown, and the cutting blade 7 sliding alone along the radial direction of the arc-shaped rotating plate 5 can be used to adjust the cutting depth of the cutting blade 7 on the surface of the pipe body 8. Since the pipe body 8 is a hollow tubular structure, the cutting radius of the cutting blade 7 only needs to be greater than the wall thickness of the pipe body 8 and does not need to be greater than the overall diameter of the pipe body 8. Compared with traditional cutting equipment, the overall size of this device and the size of the cutting blade 7 can be set smaller. On the one hand, it reduces the space occupation, and on the other hand, it reduces the overall weight of the equipment, ensuring that only a relatively small frictional force between the arc-shaped clamping plate 4 and the pipe body 8 can drive the whole device to move. Moreover, the arc-shaped clamping plate 4 only needs to provide a relatively small clamping force to clamp the pipe body 8. When facing a pipe body 8 with a smaller wall thickness, it is more difficult to clamp the pipe body 8 and deform it;

[0039] In addition, a tooth groove 53 is provided on the other side surface of the arc-shaped rotating plate 5. The two arc-shaped rotating plates 5, the two arc-shaped side plates 51 and the two tooth grooves 53 are all spliced into a circular ring shape. When the two arc-shaped translation plates 3 approach each other and are spliced into a circular ring shape, the two ends of the two arc-shaped rotating plates 5 correspond to each other respectively. At this time, by driving the tooth groove 53 with an external gear, the rotational movement of the arc-shaped rotating plate 5 can be realized, and then the cutting blade 7 can be driven to cut around the circumferential direction of the pipe body 8 on the outside of the pipe body 8. It should be noted that since two cutting blades 7 are provided in this device, the arc-shaped rotating plate 5 of this device only needs to rotate a minimum of 180 degrees. After this device cuts the pipe body 8 once, the positions of the two arc-shaped rotating plates 5 on the inner sides of the two arc-shaped translation plates 3 are interchanged. At this time, even if the two arc-shaped translation plates 3 move away from each other, the arc-shaped rotating plate 5 and the arc-shaped translation plate 3 will not separate from each other. When cutting next time, controlling the arc-shaped rotating plate 5 to rotate 180 degrees in the reverse direction can completely reset this device, thus avoiding the entanglement of the cables on this device caused by the continuous rotation of the arc-shaped rotating plate 5.

[0040] In order to guide the movement of the cutting blade 7, this application also has a guide seat 52 fixedly connected to one end of the surface of the arc-shaped side plate 51. The guide seat 52 is in a "C" shape. Radial sliding grooves 521 along the radial direction of the arc-shaped side plate 51 are opened on both inner walls of the guide seat 52. A radial slider 6 is slidably installed in the inner cavity of the guide seat 52. A limiting convex block 62 adapted to the radial sliding groove 521 is fixed on the surface of the radial slider 6. The limiting convex block 62 and the radial sliding groove 521 cooperate with each other to guide and limit the sliding of the radial slider 6 in the inner cavity of the guide seat 52, so that the radial slider 6 can only slide along the radial direction of the arc-shaped rotating plate 5, and the radial slider 6 itself is set in a cuboid structure and will not rotate during the sliding process;

[0041] Secondly, a fixed shaft 61 is fixed on one side surface of the radial slider 6, and the fixed shaft 61 movably penetrates through the middle of the cutting blade 7, asFigure 7 As shown, the fixed shaft 61 is fixed to the radial slider 6 and cannot rotate on its own. The cutting blade 7 can rotate independently outside the fixed shaft 61. A bearing is provided between the cutting blade 7 and the fixed shaft 61 to reduce the frictional force generated during rotation. A radial cylinder 522 is fixed to one end of the guide seat 52, and the movable end of the radial cylinder 522 is fixedly connected to the radial slider 6. The radial cylinder 522 is mainly used to drive the radial slider 6 to slide, so as to adjust the position of the cutting blade 7. After the cutting blade 7 finishes cutting the pipe body 8, the radial cylinder 522 contracts and drives the cutting blade 7 away from the pipe body 8, and then the mounting bracket 2 slides back in the reverse direction to facilitate the next cutting operation. A protective cover 73 is provided outside the cutting blade 7, and the protective cover 73 is fixedly connected to the fixed shaft 61. The protective cover 73 is mainly used to shield part of the cutting blade 7 to prevent the staff from accidentally touching the edge of the cutting blade 7 and getting injured.

[0042] In order to drive the cutting blade 7 to rotate and cut, the present application also has a driven pulley 71 fixedly connected to one side surface of the cutting blade 7, and the driven pulley 71 is movably sleeved outside the fixed shaft 61. The driven pulley 71 is relatively fixed to the cutting blade 7. The outside of the driven pulley 71 is connected to a driving pulley 72 through belt transmission. The driving pulley 72 is driven to rotate by a cutting motor 74 fixed to the surface of the protective cover 73. The cutting motor 74 is installed on the protective cover 73 and can be relatively fixed to the fixed shaft 61. When the cutting motor 74 works, it drives the driving pulley 72 to rotate, and then drives the driven pulley 71 and the cutting blade 7 to rotate through the belt.

[0043] In order to ensure that the cut of the pipe body 8 is smoother and more even, the two cutting blades 7 of the present application are symmetrically distributed around the center of the circle of the pipe body 8. The width dimension of the cutting edge of the cutting blade 7 is greater than the thickness of the pipe body 8, as Figure 8As can be seen, the two cutting blades 7 can cut the pipe body 8 from both sides of the surface of the pipe body 8 respectively, and the uncut areas on the pipe body 8 are also symmetrically distributed about the center. Therefore, before the cutting blades 7 completely cut off the pipe body 8, the pipe body 8 itself always has a certain anti-bending property, thus preventing the front part of the pipe body 8 from bending downward due to its own gravity and causing the pipe body 8 to break along the cut seam, and further ensuring that the cut seam of the pipe body 8 by this device is smoother and more even. There are gaps between the inner wall of the arc-shaped rotating plate 5, the inner wall of the arc-shaped side plate 51, and the surface of the driven pulley 71 and the surface of the pipe body 8. When this device is working, except for the cutting of the pipe body 8 by the cutting blades 7 and the clamping of the pipe body 8 by the arc-shaped clamping plate 4, the rest of the structures are in a non-contact state with the pipe body 8. When the cutting blades 7 complete the cutting work, the two arc-shaped translation plates 3 move away from each other, and then the arc-shaped clamping plate 4 separates from the pipe body 8, and the frictional force between the arc-shaped clamping plate 4 and the pipe body 8 disappears, and this device no longer moves synchronously with the pipe body 8.

[0044] In order to slidably connect the arc-shaped rotating plate 5 and the arc-shaped translation plate 3, this application also has an inner flange 32 fixedly connected to the inner side wall of the arc-shaped translation plate 3, and the cross-section of the inner flange 32 is in a "convex" shape or a similar structure (such as Figure 5 as shown). A guiding chute 54 is formed on the outer surface of the arc-shaped rotating plate 5, and the inner flange 32 is slidably installed in the inner cavity of the guiding chute 54 and is adapted to it. The cooperation between the guiding chute 54 and the inner flange 32 can be used to install and connect the arc-shaped translation plate 3 and the arc-shaped rotating plate 5, so that the arc-shaped rotating plate 5 can only rotate and slide along the length direction of the inner flange 32, and there will never be an axial offset between the arc-shaped rotating plate 5 and the arc-shaped translation plate 3. A second convex plate 33 is fixed to one side edge of the arc-shaped translation plate 3, a driving gear 34 is rotatably installed on the second convex plate 33, and the driving gear 34 meshes with the tooth groove 53 for transmission. A driving motor 35 is fixed to the surface of the second convex plate 33, and the output end of the driving motor 35 is fixedly connected to the driving gear 34. When the driving motor 35 works, it drives the driving gear 34 to rotate, and then drives the arc-shaped rotating plate 5 and the arc-shaped side plate 51 to rotate and move through the meshing transmission between the driving gear 34 and the tooth groove 53.

[0045] In order to control the horizontal movement of the arc-shaped translation plate 3, the mounting frame 2 of this application is integrally in a "C" shape with an upward opening, and arc-shaped fixing plates 22 are fixed to both upper ends of the mounting frame 2. The two arc-shaped fixing plates 22 are symmetrically distributed. A translation cylinder 25 is fixed to the middle of the arc-shaped fixing plate 22, and the movable end of the translation cylinder 25 is fixedly connected to the middle of the arc-shaped translation plate 3. When the translation cylinder 25 works and expands and contracts, it can drive the arc-shaped translation plate 3 and the arc-shaped fixing plate 22 to approach or move away from each other.

[0046] In order to guide the movement of the arc-shaped translation plate 3, the present application further has guide sleeves 24 fixedly connected through and penetrating at both the upper and lower ends of the arc-shaped fixed plate 22. A guide connecting rod 36 is movably penetrated through the inner cavity of the guide sleeve 24, and the end portions of the two guide connecting rods 36 are respectively fixedly connected to the upper and lower ends of the arc-shaped translation plate 3. The cooperation between the guide sleeve 24 and the guide connecting rod 36 can be used to guide the translational movement of the arc-shaped translation plate 3, and improve the stability of the sliding connection between the arc-shaped translation plate 3 and the arc-shaped fixed plate 22, avoiding tilting and rotation of the arc-shaped translation plate 3 itself.

[0047] In order to reset the sliding of the mounting frame 2, the present application further has a rib plate 23 fixedly arranged at the inner corner of the mounting frame 2. Sliding seats 21 are fixedly connected to both ends of the lower part of the mounting frame 2, and two guide rails 11 are fixed on the surface of the workbench 1. The two sliding seats 21 are respectively slidably connected to the two guide rails 11. The sliding seat 21 is in an inverted "T" shape. The cooperation between the sliding seat 21 and the guide rail 11 can be used to guide and limit the sliding of the mounting frame 2. In addition, in order to improve the stability of the sliding of the mounting frame 2, a sliding damping structure known in the prior art can also be provided between the sliding seat 21 and the guide rail 11, which will not be elaborated here. A reset member 12 is fixed on the surface of the workbench 1, and the movable end of the reset member 12 abuts against the side surface of the mounting frame 2. The end of the reset member 12 is in contact with but not fixed to the mounting frame 2. After the reset member 12 extends and moves the mounting frame 2 to the left end position of the stroke, the reset member 12 contracts and resets. Only when the arc-shaped clamping plate 4 clamps the pipe body 8, the mounting frame 2 can move synchronously with the pipe body 8 to the right until the cutting work is completed and the arc-shaped clamping plate 4 is separated from the pipe body 8. At this time, the mounting frame 2 moves to the right end of the stroke, and then the reset member 12 extends to push the mounting frame 2 to move leftward to reset, and then the above process is repeated.

[0048] In order to improve the stability of the splicing of the arc-shaped rotating plate 5, the present application further has a positioning groove 511 and a positioning boss 512 respectively arranged at the end faces of the upper and lower ends of the arc-shaped side plate 51. The positioning grooves 511 and the positioning bosses 512 on the two arc-shaped side plates 51 are respectively inserted and matched correspondingly. A chamfer is arranged at the end of the positioning boss 512. Since the two arc-shaped rotating plates 5 of the present device need to be frequently spliced and separated, the positioning grooves 511 and the positioning bosses 512 arranged at both ends of the arc-shaped side plate 51 can be used to improve the stability of the splicing of the two arc-shaped rotating plates 5 and avoid misalignment between the two.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
