[0002] In related technologies, during the production of stainless steel horizontal tubes (such as D175 stainless steel horizontal tubes), the bending stations are all independently operated, with each station not connected to the others. The operation mode is one person per machine, and the spacing between equipment is too large, resulting in wasted time and material handling. Multiple processing links are disconnected and cannot cooperate with each other, leading to excessively long unit production time for bending product cutting, which fails to meet customer delivery requirements.

[0003] In the prior art, application publication number CN115771036A discloses an automated high-precision cutting equipment for stainless steel pipe production. It uses a conveyor to transport stainless steel pipes to a laser cutting head for cutting, and then uses a grinding component for grinding. However, it cannot be applied to the cutting of bent pipe products, does not have an automatic unloading function, and the entire equipment has a linear layout, which occupies a large space.

[0066] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0067] This utility model discloses a pipe cutting machine. Because the laser cutting mechanism has X-axis and Z-axis displacement, it can be used for cutting bent pipe products. At the same time, the feeding mechanism is used to transport bent pipe products, realizes automated connection with upstream equipment, connects the upstream and downstream processes, has smooth operation, compact production rhythm, reduces the unit production time of bent pipe product cutting, and improves production efficiency. The unloading mechanism realizes automatic unloading.

[0068] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0069] like Figures 1 to 19As shown, a pipe cutting machine according to an embodiment of the present invention has a machine base. The laser cutting mechanism 2, clamping and rotating mechanism 3, material picking mechanism 4, centering mechanism 5, slag removal mechanism 6, material discharging mechanism 7, and material collecting mechanism 8 are all arranged on the machine base. A dust cover is provided on the machine base. The dust cover is equipped with a touch screen and a control box. The control box is used to control the operation of the laser cutting mechanism 2, clamping and rotating mechanism 3, material picking mechanism 4, centering mechanism 5, slag removal mechanism 6, material discharging mechanism 7, and material collecting mechanism 8. The dust cover covers the material feeding mechanism 1, laser cutting mechanism 2, clamping and rotating mechanism 3, material picking mechanism 4, centering mechanism 5, slag removal mechanism 6, material discharging mechanism 7, and material collecting mechanism 8. A waste collection box is also provided on one side of the machine base.

[0070] An embodiment of the present invention provides a pipe cutting machine comprising a feeding mechanism 1, a laser cutting mechanism 2, a clamping and rotating mechanism 3, a material taking mechanism 4, a centering mechanism 5, a slag removal mechanism 6, a material discharging mechanism 7, and a material receiving mechanism 8.

[0071] like Figures 1 to 5 As shown, the feeding mechanism 1 is used to convey bent pipe products. In some examples, the feeding mechanism 1 includes a feeding conveyor belt 11 and a pushing structure 12. The frame height of the feeding mechanism 1 is slightly higher than the machine platform height to facilitate the gripping mechanism 4 described below to grasp the bent pipe products. The feeding conveyor belt 11 and the pushing structure 12 are mounted on the frame. The feeding conveyor belt 11 is used to convey the bent pipe products. The feeding conveyor belt 11 may include a motor and a conveyor belt. The motor drives the conveyor belt to rotate through a transmission wheel, and the conveyor belt drives the bent pipe products to move. Side rails 13 may be provided on both sides of the conveyor belt in the direction of conveying the bent pipe products, and a baffle plate 14 may be provided at the end of the conveyor belt in the direction of conveying the bent pipe products. The pushing structure 12 is used to push the bent pipe products in a direction perpendicular to the conveying direction of the bent pipe products so that the bent pipe products abut against the side rails 13, which facilitates the gripping mechanism 4 described below to grasp the bent pipe products. The pushing structure 12 may include a pushing cylinder and a pushing plate. The pushing cylinder drives the pushing plate to move, and the pushing plate pushes the bent tube product in a direction perpendicular to the conveying direction of the bent tube product, that is, pushes the bent tube product to the side away from the pushing structure 12 and abuts against the side guard 13 on the other side, so as to facilitate the bending tube product being gripped.

[0072] like Figures 1 to 3 , Figure 6 and Figure 7As shown, the laser cutting mechanism 2 is used for automatic cutting of bent pipe products and has X-axis and Z-axis displacement. In some examples, the laser cutting mechanism 2 includes a first X-axis moving module 21, a first Z-axis moving module 22, and a laser head 23. The first Z-axis moving module 22 is mounted on the first X-axis moving module 21, and the laser head 23 is mounted on the first Z-axis moving module 22. Both the first X-axis moving module 21 and the first Z-axis moving module 22 can include a servo motor and a lead screw. The servo motor drives the lead screw to rotate, the lead screw drives the slider to slide, and thus drives the laser head 23 to move. The servo motor can be a GGMSMD042G1U motor (Panasonic 400W), and the laser head 23 can be an LC218-F150 pointed laser head. The laser head 23 can have X-axis and Z-axis displacement under the drive of the first X-axis moving module 21 and the first Z-axis moving module 22, so that the laser cutting mechanism 2 can be used for cutting bent pipe products.

[0073] like Figures 1 to 3 , Figure 8 and Figure 9 As shown, the clamping rotary mechanism 3 is used to clamp the bent pipe product to facilitate cutting by the laser cutting mechanism 2. The clamping rotary mechanism 3 can also be used to rotate the bent pipe product to facilitate cutting by the laser cutting mechanism 2. In some examples, the clamping rotary mechanism 3 includes a rotating module 31 and a clamping module 32. The clamping module 32 is mounted on the rotating module 31 and is used to clamp and rotate the bent pipe product. The rotating module 31 may include a rotating structure 311, a reducer 312, a drive shaft 313, and a connecting plate 314. The rotating structure 311 is connected to the reducer 312, the reducer 312 is connected to the drive shaft 313, and the drive shaft 313 is connected to the connecting plate 314, so that the rotating structure 311 drives the connecting plate 314 to rotate. The rotating structure 311 can be a servo motor, and the reducer 312 can be a planetary reducer. The clamping module 32 is mounted on the connecting plate 314. The clamping module 32 may include an opening and closing structure 321, an upper mold 322, and a lower mold 323. The opening and closing structure 321 is connected to the upper mold 322 and the lower mold 323 respectively, and drives the upper mold 322 and the lower mold 323 to open and close. The opening and closing structure 321 may be a cylinder, which is mounted on the connecting plate 314. The clamping rotation mechanism 3 can clamp and rotate the bent tube product to different directions to facilitate cutting by the laser cutting mechanism 2.

[0074] like Figures 1 to 3 , Figure 10 and Figure 11As shown, the material handling mechanism 4 is used to grip the bent pipe product to the clamping rotary mechanism 3. In some examples, the material handling mechanism 4 includes a second X-axis moving module 41, a second Z-axis moving module 42, and grippers 43; the second Z-axis moving module 42 is disposed on the second X-axis moving module 41; the grippers 43 are disposed on the second Z-axis moving module 42, and there are two grippers 43 spaced apart. The second X-axis moving module 41 may include a moving cylinder 411 and a moving base 412, the moving cylinder 411 driving the moving base 412 to move along the X-axis direction on the slide rail 413; the second Z-axis moving module 42 may include a lifting cylinder, the lifting cylinder is disposed on the moving base 412; the grippers 43 may be gripper cylinders, the gripper cylinders are disposed on the lifting cylinders, and the grippers 43 are used to grip the bent pipe product.

[0075] like Figures 1 to 3 , Figure 12 and Figure 13 As shown, in some examples, the pipe cutting machine also includes a centering mechanism 5, which centers the bent pipe product so that it is positioned below the gripper of the material handling mechanism 4. The centering mechanism 5 may include an X-axis pushing structure 51, a Y-axis pushing structure 52, and a baffle 53. The X-axis pushing structure 51 is used to push the bent pipe product in the X-axis direction; the Y-axis pushing structure 52 is used to push the bent pipe product in the Y-axis direction; and the baffle 53 is used to block the bent pipe product. The X-axis pushing structure 51, the Y-axis pushing structure 52, and the baffle 53 are mounted on a base plate 54. Both the X-axis pushing structure 51 and the Y-axis pushing structure 52 may include a cylinder and a push plate. The cylinder is connected to the push plate and pushes the push plate to move.

[0076] In some examples, of the two grippers 43, the first gripper 43 is used to grip the bent pipe product onto the base plate 54 of the centering mechanism 5, while the second gripper 43 is used to grip the bent pipe product on the base plate 54 of the centering mechanism 5 onto the clamping rotary mechanism 3. That is, the distance between the first gripper 43 and the second gripper 43 is approximately equal to the distance between the second gripper 43 and the clamping rotary mechanism 3. The two grippers 43 grip one bent pipe product from the feed conveyor 11 onto the centering mechanism 5, and at the same time grip the other bent pipe product on the centering mechanism 5 onto the clamping rotary mechanism 3. This makes the structure compact and reduces the number of processes and structural components.

[0077] The base plate 54 of the centering mechanism 5 is at approximately the same height as the feeding conveyor belt 11 of the feeding mechanism 1, facilitating the first gripper 43 to grip the bent pipe product onto the base plate 54 of the centering mechanism 5. Simultaneously, the second gripper 43 grips the bent pipe product on the base plate 54 of the centering mechanism 5 and transfers it to the clamping rotary mechanism 3. The base plate 54 of the centering mechanism 5 is at approximately the same height as the upper die 322 and lower die 323 of the clamping rotary mechanism 3, facilitating the second gripper 43 to grip the bent pipe product on the base plate 54 of the centering mechanism 5 and transfer it to the clamping rotary mechanism 3.

[0078] Because the laser cutting mechanism 2 has X-axis and Z-axis displacement, it can be used for cutting bent pipe products. At the same time, the feeding mechanism 1 is used to transport bent pipe products, realizing automated connection with upstream equipment, seamless connection between upstream and downstream processes, smooth operation, compact production cycle, reducing unit production time for bent pipe product cutting, improving production efficiency, and orderly completing the upstream and downstream processing flow of a single bent pipe product. This efficient unitized operation mode provides a favorable foundation for the development of "U-shaped lines".

[0079] like Figures 1 to 3 , Figure 14 and Figure 15 As shown, in some examples, the pipe cutting machine also includes a slag removal mechanism 6, which is used to remove debris generated during the cutting of the bent pipe product. The slag removal mechanism 6 may include a moving structure 61 and a slag blowing pipe 62, which is mounted on the moving structure 61 and connected to an air source. The moving structure 61 may be a cylinder connected to a mounting plate, on which the slag blowing pipe 62 is mounted. Since iron filings are generated during pipe cutting, to prevent them from sticking to the pipe cavity and affecting the surface finish of the bent pipe product, the slag removal mechanism 6 works simultaneously, removing slag while cutting to ensure product quality.

[0080] like Figures 1 to 3 , Figures 16 to 19 As shown, in some examples, the pipe cutting machine also includes a discharge mechanism 7 and a receiving mechanism 8, wherein the discharge mechanism 7 is used to pick up the bent pipe product and send it to the receiving mechanism 8, and the receiving mechanism 8 is used to collect the bent pipe product.

[0081] like Figures 16 to 17 As shown, the discharge mechanism 7 includes a third X-axis moving module 71, a third Z-axis moving module 72, and a gripper 73. The third Z-axis moving module 72 is mounted on the third X-axis moving module 71; the gripper 73 is mounted on the third Z-axis moving module 72. The third X-axis moving module 71 may include a sliding cylinder 711 and a sliding seat 712. The sliding cylinder 711 drives the sliding seat 712 to move along the X-axis direction on the slide rail 713. The third Z-axis moving module 72 may include a lifting cylinder, which is mounted on the sliding seat 712. The gripper 73 may include a clamping cylinder and a clamping plate. The clamping cylinder is mounted on the lifting cylinder, and the clamping plate is mounted on the clamping cylinder. The clamping plate grips the bent tube product to the receiving mechanism 8, where it falls under gravity. The discharge mechanism 7 is coaxially arranged with the clamping rotary mechanism 3 to facilitate the gripper 73 of the discharge mechanism 7 to grip the bent tube product from the clamping rotary mechanism 3.

[0082] like Figures 18 to 19As shown, the receiving mechanism 8 includes an inclined slide 81, a stop 82, and a receiving plate 83. The stop 82 is located at the lower end of the inclined slide 81 to restrict the cut bent pipe products. The bent pipe products slide down towards the stop 82 under the action of gravity. The inclined slide 81 can be a sliding surface provided on a material rack, which can be a stainless steel rack. The receiving plate 83 is movably located at the upper end of the inclined slide 81 to push the cut bent pipe products. Specifically, a cylinder is provided at the upper end of the inclined slide 81, and the cylinder is connected to the receiving plate 83. A receiving rack 84 is provided between the cylinder and the receiving plate 83 to facilitate the collection of bent pipe products.

[0083] In this invention, when cutting bent pipe products, after the upstream bending process is completed, the bent pipe products are placed into the feeding conveyor belt 11, allowing them to be conveyed sequentially and ensuring the feeding stroke distance of the bent pipe products. At this time, the material detection probe responds and feeds a signal back to the pushing structure 12. Upon receiving the signal, the pushing structure 12 stops the bent pipe products. The first gripper 43 of the picking mechanism 4 picks up the bent pipe products and places them onto the base plate 54 of the centering mechanism 5. Then, the centering mechanism 5 starts working, and the push plate of the centering mechanism 5 extends to center the bent pipe products so that they fall directly below the second gripper 43 of the picking mechanism 4 for easy picking. At this time, the gripper 43 of the picking mechanism 4 begins its grasping action, and the second gripper 43 picks up the bent pipe products from the base plate 54 of the centering mechanism 5 and places them onto the laser cutting mechanism 2. Simultaneously, the clamping rotation mechanism 3 responds, and the upper mold 322 and lower mold 323 of the clamping rotation mechanism 3 close, clamping the bent pipe products and preventing displacement and loosening. Then, the system information is retrieved and fed back to the traveling mechanism of the laser cutting mechanism 2. The laser head 23 receives the execution command and enters the calibration mode. The feed speed and light intensity of the laser head 23 are adjusted according to the wall thickness parameters of the pipe. Then, the focal length of the X, Y, and Z axes is finely adjusted to prevent the laser head 23 from getting too close and burning. Next, the turntable and the light column start synchronously. The energy light column focused by the laser continuously makes a circular motion around the center until the bent pipe product is quickly and accurately cut. Since iron filings are generated when cutting the pipe, in order to prevent them from sticking in the pipe cavity and affecting the end surface smoothness of the bent pipe product, the slag removal mechanism 6 works simultaneously, removing slag while cutting to ensure the quality of the bent pipe product. After the operation is completed, the discharge mechanism 7 will grab the bent pipe product to the receiving mechanism 8. The receiving mechanism 8 will move the processed bent pipe product laterally to the receiving rack 84. The receiving rack 84 receives the execution command and extends the receiving plate 83 to retract the bent pipe product again to prevent the bent pipe product from getting stuck in the receiving mechanism 8.
