Description

Technical Field

[0001] This invention relates to the field of automatic feeding rotary circumferential cutting technology for metal pipes, specifically to an automatic feeding rotary circumferential cutting device for metal pipes and its circumferential cutting method. Background Technology

[0002] Pipe cutting technology has wide applications in industrial production, building construction, and pipeline maintenance. In these applications, pipes typically need to be cut to specific lengths to meet different engineering requirements.

[0003] For example, Chinese patent CN118492687B discloses a metal pipe cutting device, comprising: a cutting platform; a support pipe disposed on top of the cutting platform for supporting a metal pipe; a cutting section disposed on the cutting platform for cutting the metal pipe; a ring disposed on the cutting platform, fitted over the metal pipe, the ring having multiple rollers; a positioning part that limits the position of the metal pipe, ensuring that the metal pipe will not retract; and a limited and fixed distance for the driving component to move the ring, ensuring that the distance the metal pipe is pushed to the cutting section is consistent each time, thus achieving fixed-length cutting of the metal pipe. The purpose is to address these issues by providing a new type of rotary circumferential cutting equipment. The clamping and positioning parts are designed to work in tandem with the direction of the circumferential tube's movement, eliminating cumbersome steps and significantly improving cutting efficiency and precision. Traditional rotary circumferential cutting equipment requires a chuck to fix the metal tube, rotate it, and then cut it with a laser. However, the chuck fixes the metal tube to a fixed size. When adjusting the size of the metal tube, the clamping arms on the chuck must be disassembled, adjusted, and reinstalled. This adjustment process is time-consuming and the precision is difficult to control. Therefore, this paper proposes an automatic feeding rotary circumferential cutting equipment for metal tubes and its circumferential cutting method to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an automatic feeding rotary circumferential cutting device for metal pipes and its circumferential cutting method. It offers advantages such as convenient adjustment of the clamping arm position and fixation of metal pipes of different specifications, thus solving the problems of complex clamping arm adjustment and poor precision in traditional methods.

[0005] (II) Technical Solution To achieve the above-mentioned purpose of conveniently adjusting the position of the clamping arms, the present invention provides the following technical solution: an automatic feeding rotary ring cutting device for metal pipes, including a frame, a card seat rotatably mounted on the front outer surface of the frame, an adjusting outer ring mounted on the front end of the card seat, clamping arms mounted around the outer surface of the card seat, and an adjusting component provided at one end of the clamping arm, the position of the clamping arm being adjusted by the adjusting component. The slide is mounted on the outer surface of the frame, and the slide is provided above the adjusting outer ring. The outer surface of the slide is slidably mounted with a mounting base, the outer surface of the mounting base is slidably mounted with a front seat, and the front outer surface of the front seat is fixedly mounted with a laser emitter. The conveyor frame is located at the rear end of the machine frame. A box is slidably installed on the top outer surface of the conveyor frame. A moving component is installed inside the box. The moving component drives the box to slide along the conveyor frame. A chuck and a guide seat are fixedly installed on the top of the box. A clamping plate assembly is installed on one side outer surface of the chuck.

[0006] Preferably, a lead screw is provided on the outer surface of the frame at the rear end of the mounting base, and mounting brackets are provided at both ends of the lead screw, with both ends of the lead screw rotatably connected to the mounting brackets. A second motor is fixedly installed on the outer surface of the frame at one end of the lead screw, and one end of the output shaft of the second motor is fixedly connected to one end of the lead screw. A movable frame is fixedly installed on the outer surface of the rear end of the mounting base, and the lead screw is threadedly connected to the movable frame. A cylinder is fixedly installed on the top end of the mounting base, and the bottom end of the output shaft of the cylinder is fixedly connected to the outer surface of the front seat. When the second motor is started, it drives the lead screw in the mounting bracket to rotate, causing the mounting base to slide laterally along the slide. At the same time, the cylinder can drive the front seat to slide up and down, so that the bottom end of the laser emitter corresponds to the cutting position.

[0007] Preferably, a gear ring is rotatably mounted on the rear outer surface of the slide, and a first motor is fixedly mounted on the front outer surface of the frame. A first gear is fixedly mounted on one end of the output shaft of the first motor, and the first gear meshes with the gear ring. The gear ring is fixedly connected to the rear outer surface of the clamp. While the laser emitter emits laser cutting, the first motor drives the first gear to rotate, the first gear drives the gear ring, and the gear ring drives the clamp to rotate, thereby driving the metal tube to rotate and cut through the clamp arm.

[0008] Preferably, the adjustment assembly includes a fixed base fixedly installed on the outer surface of the card holder, and one end of the clamping arm is slidably connected to the fixed base. The other end of the clamping arm is provided with a pressure roller, so that the metal tube is fixed by the pressure roller at one end of the clamping arm when cutting the metal tube.

[0009] Preferably, an adjusting gear is rotatably mounted on the outer surface of one end of the fixed base, and a first adjusting screw is rotatably mounted inside the fixed base. One end of the first adjusting screw is fixedly connected to the outer surface of the adjusting gear. One end of the clamping arm is threadedly connected to the adjusting gear. The adjusting gear meshes with the inner wall of the adjusting outer ring. By rotating the adjusting outer ring, the adjusting gear is driven to rotate, causing the first adjusting screw at one end of the adjusting gear to drive the clamping arm to slide along the fixed base, thereby adjusting the position of the clamping arm according to the specifications of the metal tube.

[0010] Preferably, a rotating ring is fixedly installed at one end of the adjusting outer ring, and the adjusting outer ring is rotatably connected to the card seat through the rotating ring. A limit pin is inserted into one side of the outer surface of the card seat, and a plurality of limit holes matching the limit pin are opened on the outer surface of the rotating ring. Pulling the limit pin outward causes one end of the limit pin to disengage from the limit hole on the surface of the rotating ring, thereby releasing the limitation on the adjusting outer ring.

[0011] Preferably, the moving assembly includes a base frame fixedly installed inside the housing and a third motor fixedly installed on the top of the base frame. Two sets of transmission wheels are rotatably installed inside the base frame, and a transmission belt is fitted on the outer surface of the transmission wheels. The bottom end of the output shaft of the third motor is fixedly connected to one end of the transmission wheel, and the bottom end of the other end of the transmission wheel is fixedly connected to a second gear. A rack is fixedly installed on one side of the top of the conveyor frame, and the second gear meshes with the rack. When the third motor is started, it drives the transmission wheel at one end to rotate, which drives the second gear to rotate through the transmission belt and the transmission wheel. The second gear meshes with the rack on the conveyor frame, thereby driving the housing to slide forward along the conveyor.

[0012] Preferably, the clamp assembly includes a slider that slides around the outer surface of one side of the chuck. A guide tube is fixedly installed on one side of the outer surface of the slider. A connecting rod is slidably installed inside the guide tube. A second adjusting screw is threadedly connected to the inside of the connecting rod. A clamp is fixedly installed at one end of the connecting rod. A knob is rotatably installed on the other side of the outer surface of the slider. One end of the knob is fixedly connected to one end of the second adjusting screw. By rotating the knob, the second adjusting screw at one end is driven, causing the second adjusting screw to drive the connecting rod to push the clamp along the guide tube, adjusting the initial position of the clamp, thereby facilitating the clamp to fix metal tubes of different specifications.

[0013] Preferably, a guide rod is fixedly installed around the inside of the chuck. A connecting block and an electromagnet are sleeved on the outer surfaces of both ends of the guide rod. A return spring is sleeved on the outer surface of the guide rod between the connecting block and the electromagnet. The outer surface of the connecting block is fixedly connected to the slider. When the electromagnet at one end of the guide rod is activated, the slider is attracted by magnetic force and slides inward along the guide rod, thereby driving the clamp at one end of the guide tube to fix the surface of the metal tube.

[0014] A circumferential cutting method for an automatic feeding rotary circumferential cutting device for metal pipes, comprising the following steps: Step 1: Pass the metal tube through the guide seat and the chuck in sequence, so that one end of the metal tube comes out of the chuck. Step 2: Fix the metal tube with the pressure roller at one end of the clamping arm, and move the laser emitter by the second motor and cylinder so that the bottom end of the laser emitter corresponds to the cutting position of the metal tube; Step 3: Start the laser emitter to emit a laser, and at the same time start the first motor to drive the cassette to rotate, thereby driving the metal tube to rotate, and use the laser to perform circumferential cutting on the metal tube; Step 4: Start the electromagnet to clamp the metal tube through the clamping plate. After the metal tube at the front end is cut, start the third motor to slide the box forward and push the metal tube forward. Step 5: After the metal tube is pushed a fixed distance, the clamp releases the metal tube, and the third motor drives the box to reset. After the metal tube is cut, it continues to be conveyed forward, and so on.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an automatic feeding rotary circumferential cutting device for metal pipes and a circumferential cutting method thereof, which has the following beneficial effects: By engaging with the adjusting gear through the inner wall of the adjusting outer ring, the position of the clamping arm can be adjusted by rotating the adjusting outer ring along the card seat, thereby driving the adjusting gear to rotate. This causes the first adjusting screw at one end of the adjusting gear to drive the clamping arm to slide along the fixed seat, thus making it convenient to adjust the position of the clamping arm according to the specifications of the metal tube. The slider is controlled to move back and forth by an electromagnet and a return spring, thereby controlling the clamping plate on the chuck to clamp and release the metal tube. The second adjusting screw at one end can be driven by rotating the knob, which in turn drives the connecting rod to push the clamping plate along the guide tube, adjusting the initial position of the clamping plate, thus facilitating the clamping plate to fix metal tubes of different specifications.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figure 1-6 The present invention provides the following technical solution: an automatic feeding rotary ring cutting device for metal pipes and a ring cutting method thereof, comprising a frame 1, a card seat 21 rotatably mounted on the front outer surface of the frame 1, an adjusting outer ring 2 mounted on the front end of the card seat 21, clamping arms 23 mounted around the outer surface of the card seat 21, and an adjusting component provided at one end of the clamping arm 23, the position of the clamping arm 23 being adjusted by the adjusting component; In this embodiment, the slide 3 is installed on the outer surface of the frame 1, and the slide 3 is provided above the adjusting outer ring 2. The outer surface of the slide 3 is slidably mounted with a mounting base 31, the outer surface of the mounting base 31 is slidably mounted with a front seat 37, and the front end outer surface of the front seat 37 is fixedly mounted with a laser emitter 38. The frame 1 has a lead screw 34 located at the rear end of the mounting base 31 on its outer surface. Mounting brackets 33 are mounted at both ends of the lead screw 34, and the two ends of the lead screw 34 are rotatably connected to the mounting brackets 33. A second motor 35 is fixedly mounted at one end of the lead screw 34 on the outer surface of the frame 1, and one end of the output shaft of the second motor 35 is fixedly connected to one end of the lead screw 34. A movable frame 32 is fixedly mounted on the outer surface of the rear end of the mounting base 31, and the lead screw 34 is threadedly connected to the movable frame 32. A cylinder 36 is fixedly mounted at the top of the mounting base 31, and the bottom end of the output shaft of the cylinder 36 is fixedly connected to the outer surface of the front seat 37. Starting the second motor 35 rotates the lead screw 34 within the mounting bracket 33, causing the mounting base 31 to slide laterally along the slide 3. Simultaneously, the cylinder 36 can drive the front seat 37 to slide up and down, aligning the bottom end of the laser emitter 38 with the cutting position.

[0020] In this embodiment, a gear ring 22 is rotatably mounted on the outer rear surface of the slide 3, and a first motor 24 is fixedly mounted on the outer front surface of the frame 1. A first gear 241 is fixedly mounted on one end of the output shaft of the first motor 24, and the first gear 241 meshes with the gear ring 22. The gear ring 22 is fixedly connected to the outer rear surface of the clamp 21. While the laser emitter 38 emits laser for cutting, the first motor 24 drives the first gear 241 to rotate, the first gear 241 drives the gear ring 22, and the gear ring 22 drives the clamp 21 to rotate, thereby driving the metal tube to rotate and cut through the clamping arm 23.

[0021] In this embodiment, the adjustment component includes a fixed base 25 fixedly installed on the outer surface of the card holder 21, and one end of the clamping arm 23 is slidably connected to the fixed base 25. The other end of the clamping arm 23 is provided with a pressure roller 231. When cutting the metal tube, the metal tube 231 is fixed by the pressure roller at one end of the clamping arm 23.

[0022] The fixed base 25 has an adjusting gear 26 rotatably mounted on one end of its outer surface. A first adjusting screw 261 is rotatably mounted inside the fixed base 25, with one end of the first adjusting screw 261 fixedly connected to the outer surface of the adjusting gear 26. One end of the clamping arm 23 is threadedly connected to the adjusting gear 26. The adjusting gear 26 meshes with the inner wall of the adjusting outer ring 2. Rotating the adjusting outer ring 2 drives the adjusting gear 26 to rotate, causing the first adjusting screw 261 at one end of the adjusting gear 26 to drive the clamping arm 23 along the fixed base. 25 slides to adjust the position of the clamping arm according to the specifications of the metal tube. One end of the adjusting outer ring 2 is fixedly installed with a rotating ring 211, and the adjusting outer ring 2 is rotatably connected to the card seat 21 through the rotating ring 211. A limit pin 213 is inserted into one side of the outer surface of the card seat 21. The outer surface of the rotating ring 211 is provided with several limit holes 212 that match the limit pin 213. Pulling the limit pin 213 outward causes one end of the limit pin 213 to disengage from the limit hole 212 on the surface of the rotating ring 211, thereby releasing the limitation on the adjusting outer ring 2.

[0023] The working principle of this embodiment is as follows: When cutting the metal tube, the metal tube 231 is fixed by the pressure roller at one end of the clamping arm 23. Then, the second motor 35 is started to drive the lead screw 34 in the mounting frame 33 to rotate, which drives the mounting seat 31 to slide laterally along the slide 3. At the same time, the front seat 37 can be driven up and down by the cylinder 36 so that the bottom end of the laser emitter 38 corresponds to the cutting position. While the laser emitter 38 emits laser for cutting, the first motor 24 drives the first gear 241 to rotate. The first gear 241 drives the gear ring 22, which in turn drives the clamping seat 21 to rotate, thereby driving the metal tube to rotate and cut through the clamping arm 23. When the position of the clamping arm 23 needs to be adjusted according to the specifications of the metal tube, first pull the limiting pin 213 outward so that one end of the limiting pin 213 disengages from the limiting hole 212 on the surface of the rotating ring 211, thereby releasing the limitation on the adjusting outer ring 2. Then, by rotating the adjusting outer ring 2, the adjusting gear 26 is driven to rotate, so that the first adjusting screw 261 at one end of the adjusting gear 26 drives the clamping arm 23 to slide along the fixed seat 25, thereby adjusting the position of the clamping arm according to the specifications of the metal tube.

[0024] Example 2 Please see Figure 7-10 The present invention provides the following technical solution: an automatic feeding rotary ring cutting device for metal pipes and a ring cutting method thereof, comprising a conveyor frame 4 disposed at the rear end of a frame 1, a housing 5 slidably mounted on the top outer surface of the conveyor frame 4, a moving component disposed inside the housing 5, the moving component driving the housing 5 to slide along the conveyor frame 4, a chuck 51 and a guide seat 52 fixedly mounted on the top of the housing 5, and a clamping plate assembly mounted on one side outer surface of the chuck 51.

[0025] In this embodiment, the moving component includes a base frame 531 fixedly installed inside the housing 5 and a third motor 53 fixedly installed on the top of the base frame 531. Two sets of transmission wheels 532 are rotatably installed inside the base frame 531. A transmission belt 533 is sleeved on the outer surface of the transmission wheels 532. The bottom end of the output shaft of the third motor 53 is fixedly connected to one end of the transmission wheel 532, and the bottom end of the other end of the transmission wheel 532 is fixedly connected to a second gear 55. A rack 41 is fixedly installed on one side of the top of the conveyor frame 4, and the second gear 55 is meshed with the rack 41. When the third motor 53 is started, it drives the transmission wheel 532 at one end to rotate. Through the transmission belt 533 and the transmission wheel 532, it drives the second gear 56 to rotate. The second gear 55 is meshed with the rack 41 on the conveyor frame 4, thereby driving the housing 5 to slide forward along the conveyor.

[0026] In this embodiment, the clamping plate assembly includes a slider 54 that slides around the outer surface of one side of the chuck 51. A guide tube 56 is fixedly installed on one side of the outer surface of the slider 54. A connecting rod 562 is slidably installed inside the guide tube 56. A second adjusting screw 563 is threadedly connected inside the connecting rod 562. A clamping plate 561 is fixedly installed at one end of the connecting rod 562. A knob 541 is rotatably installed on the other side of the outer surface of the slider 54. One end of the knob 541 is fixedly connected to one end of the second adjusting screw 563. By rotating the knob 541, the second adjusting screw 563 is driven at one end, causing the second adjusting screw 563 to drive the connecting rod 562 to push the clamping plate 561 along the guide tube 56, adjusting the initial position of the clamping plate 561, thereby facilitating the clamping plate 561 to fix metal tubes of different specifications.

[0027] The chuck 51 has a guide rod 58 fixedly installed around its interior. The outer surfaces of the two ends of the guide rod 58 are fitted with connecting blocks 57 and electromagnets 59. A return spring 581 is fitted between the connecting blocks 57 and electromagnets 59 on the outer surface of the guide rod 58. The outer surface of the connecting blocks 57 is fixedly connected to the slider 54. When the electromagnet 59 at one end of the guide rod 58 is activated, the slider 54 is attracted by the magnetic force and slides inward along the guide rod 58, thereby driving the clamp 561 at one end of the guide tube 56 to fix the surface of the metal tube.

[0028] The working principle of this embodiment is as follows: During the conveying and feeding process of the metal tube, the metal tube is first passed through the guide seat 5 and the chuck 51 in sequence. Then, the electromagnet 59 at one end of the guide rod 58 is activated. The slider 54 is attracted by the magnetic force and slides inward along the guide rod 58, thereby driving the clamp 561 at one end of the guide tube 56 to fix the surface of the metal tube. Then, the third motor 53 is activated, driving the transmission wheel 532 at one end to rotate. Through the transmission belt 533 and the transmission wheel 532, the second gear 56 is driven to rotate. The second gear 55 meshes with the rack 41 on the conveyor frame 4, thereby driving the box 5 to slide forward along the conveyor, thereby driving the metal tube to be fed. After the metal tube is pushed forward a certain distance, the electromagnet 59 is turned off. The return spring 581 will reset the slider 54 outward, releasing the metal tube. Then, the second gear 55 drives the box 5 to reset. This cycle continues, driving the metal tube to be continuously pushed forward. By rotating the knob 541, the second adjusting screw 563 at one end is driven, which in turn drives the connecting rod 562 to push the clamp 561 along the guide tube 56, thereby adjusting the initial position of the clamp 561 and making it easier for the clamp 561 to fix metal tubes of different specifications.
