Description

Technical Field

[0001] The present invention relates to the field of metal cutting, and more particularly to a metal pipe cutting machine with a rotating tool holder. Background Art

[0002] In the field of metal processing, metal pipe cutting machines, as key equipment for achieving precise pipe cutting, are widely used in many industries such as construction, machinery manufacturing, and the automotive industry. With the continuous improvement of industrial production requirements for pipe cutting accuracy, efficiency, and applicable pipe types, traditional metal pipe cutting machines have gradually exposed some performance shortcomings. The driving mode of its rotating tool holder is mostly a single drive structure. The single drive mode has obvious limitations: during the cutting process, especially when facing metal pipes with thick walls and high material hardness, the required cutting force is large, and the load on the meshing point of the single rack and gear ring is concentrated, which not only easily leads to increased wear of the rack and gear ring and shortens the service life of the equipment, but also makes it difficult to provide sufficient driving torque, resulting in insufficient rotational stability of the rotating tool holder, which in turn affects the cutting accuracy and may even cause jamming, reducing processing efficiency.

[0029] like Figure 4-6 and 9;

[0030] The metal pipe cutting machine with a rotating tool holder includes a rotating tool holder 101, which is rotatably connected to the inner circumference of a collar 102. Two baffles 107 are fixed to the tool holder 101, one on either side of the collar 102. A gear ring 108 is fixed to the left side of the tool holder 101, driven by two upper and lower racks 304. When the upper and lower racks 304 begin to operate, they produce linear motion, which, through the tight engagement of the teeth, is converted into circular motion for the gear ring 108. Because the gear ring 108 is securely attached to the tool holder 101, its rotation drives the tool holder 101 in a circular rotation about the central axis of the collar 102. The two baffles 107, one on either side of the collar 102, constantly limit the axial displacement of the tool holder 101 during its rotation. Without baffle 107, the rotating blade holder 101 could experience axial movement during rotation due to various external interferences, such as reaction forces during cutting and equipment vibrations. This would significantly affect cutting accuracy and equipment stability. The rotating blade holder 101 can only rotate stably along a predetermined circular path, ensuring accurate and stable cutting. The two racks 304 simultaneously drive the gear ring 108 and the rotating blade holder 101, allowing the rotating blade holder 101 to drive the cutting blade 103 for powerful cutting, enhancing cutting force and making it easy to cut thick, hard metal pipes.

[0031] like Figure 4-5 and 9;

[0032] A boss 104 is fixed to the right side of the rotary tool holder 101. A slide post 106 is vertically slidably connected to the boss 104. A cutting blade 103 is fixed to the end of the slide post 106. The slide post 106 is radially arranged on the rotary tool holder 101. A telescopic rod 105 is fixed to the slide post 106. The telescopic end of the telescopic rod 105 is fixed to the boss 104. When the telescopic rod 105 is extended or retracted, it causes the slide post 106 to slide vertically on the boss 104. Because the slide post 106 is radially arranged, its sliding movement can change the radial position of the cutting blade 103 relative to the rotary tool holder 101, thereby adapting to the cutting requirements of pipes of varying diameters and coordinating with the rotation of the rotary tool holder 101 to achieve the cutting action. In actual metal pipe cutting operations, when faced with pipes of varying diameters, such as in the construction industry where pipes used for scaffolding have a variety of diameters, it is necessary to precisely adjust the distance between the cutting blade 103 and the center of the pipe. By precisely controlling the telescopic length of the telescopic rod 105, the position of the cutting blade 103 can be precisely controlled, thereby ensuring that the cutting blade 103 can accurately and efficiently cut pipes of different diameters to meet diverse production needs.

[0033] like Figure 4-5 As shown;

[0034] Since a support column 110 is fixed to the lower side of the collar 102 and a slide 109 is fixed to the lower end of the support column 110, the support column 110 transfers the weight of the collar 102, the rotating tool holder 101 and other components to the slide 109, so that these components can move with the slide 109, providing a support basis for overall position adjustment.

[0035] like Figure 5-6 As shown;

[0036] When the tool holder 101 is in the unlocked position, the gear 302 is locked and the two ends of the gear 303 are locked. In actual operation, by precisely controlling the extension and retraction amount and speed of the two telescopic rods 305, for example, when cutting metal pipes of different materials and diameters, the telescopic parameters of the telescopic rods 305 are precisely adjusted according to the required cutting force and cutting speed, thereby achieving precise control of the rotation speed and angle of the rotating tool holder 101, thereby meeting diverse cutting process requirements and improving cutting quality and efficiency.

[0037] like Figure 4 As shown;

[0038] Since the slide 109 is slidably connected to the track 203 on the base 201, a motor 205 is fixed on the base 201, and a screw rod 204 is fixed on the output shaft of the motor 205. The screw rod 204 is matched with the slide 109 through a thread, and the motor 205 drives the screw rod 204 to rotate. Since the screw rod 204 is matched with the slide 109 through a thread, the rotation of the screw rod 204 is converted into the sliding of the slide 109 along the track 203, thereby driving the rotating tool holder 101 and other components to move as a whole, thereby realizing the adjustment of the cutting position.

[0039] like Figure 7-8 As shown;

[0040] Because a disc 501 is positioned on each side of the rotating tool holder 101, and cones 506 are fixed to the opposing surfaces of the two discs 501, the two discs 501 can move closer or further away from each other. The cones 506 on the two discs 501 can be inserted into the ends of the pipe. When the discs 501 move closer together, the cones 506 clamp the pipe, preventing it from shaking during cutting. When they move further away from each other, they facilitate the removal and placement of the pipe, serving to position and secure it. The special shape of the cones 506 allows them to fit tightly against the ends of the pipe, providing strong friction and clamping force, effectively preventing the pipe from shifting or shaking due to cutting forces during the cutting process. This ensures cutting accuracy, avoids cutting deviations caused by pipe displacement, and improves product quality.

[0041] like Figure 7-8 As shown;

[0042] Because L-shaped pieces 503 are fixed to the upper and lower ends of the disc 501, each L-shaped piece 503 is vertically slidably connected to a short column 504, and the opposite ends of the two short columns 504 are fixed to a V-shaped piece 502. Each L-shaped piece 503 is fixed to a telescopic rod 4 505, and the telescopic ends of the two telescopic rods 4 505 are respectively fixed to the ends of the two short columns 504. The telescopic rod 4 505 is extended and retracted to push the short columns 504 to slide vertically on the L-shaped piece 503, so that the V-shaped piece 502 moves closer to or away from the pipe. The V-shaped piece 502 cooperates with the cone 506 to further clamp pipes of different diameters and improve the firmness of the pipe fixation. At this time, by controlling the telescopic length of the telescopic rod 4 505, the distance between the V-shaped pieces 502 can be flexibly adjusted. The V-shaped structure of the V-shaped member 502 allows it to better adapt to the outer contours of pipes of varying diameters. It cooperates with the cone 506 to clamp the pipe from multiple directions, further enhancing the secure hold of the pipe, ensuring it remains stable during the cutting process and improving cut quality. Once the cut is complete, the two discs 501 can be driven away from each other. Since the two V-shaped members 502 on the discs 501 clamp the ends of the pipe, the two sections of the cut sheet can be separated left and right, facilitating separation after the pipe is cut.

[0043] like Figure 7-8 As shown;

[0044] Since the two discs 501 are fixed with connecting posts 507 at their diverging ends, and the two connecting posts 507 are respectively fixed to the upper parts of the two upper posts 401, the connecting posts 507 connect the discs 501 to the upper posts 401, so that the discs 501 can change their positions as the upper posts 401 move, thereby adjusting the positions of the discs 501 and the cones 506 relative to the rotating tool holder 101 to adapt to the cutting of pipes of different lengths.

[0045] like Figure 4 and 7 -8 shown;

[0046] Since the two upper columns 401 are respectively vertically slidably connected to the upper portions of the two lower columns 405, and the two lower columns 405 are respectively slidably connected to the left and right ends of the track 203, telescopic rods 202 are fixed to the left and right ends of the base 201, and the telescopic ends of the two telescopic rods 202 are respectively fixed to the two lower columns 405. When the telescopic rods 202 are extended or retracted, they can drive the lower columns 405 to slide left and right on the track 203, thereby driving the upper column 401 to move left and right, thereby adjusting the position of the disc 501 and the cone 506 relative to the rotating tool holder 101 to adapt to the cutting of pipes of different lengths.

[0047] like Figure 7-8 As shown;

[0048] Since the front sides of the upper column 401 and the lower column 405 are fixed with a protrusion 404, an elastic rod 403 is fixed between the two protrusions 404, a protrusion 407 is fixed on the outer side of the upper column 401, and a telescopic rod 402 is fixed on the lower column 405. A door-shaped piece 406 is fixed on the upper end of the telescopic rod 402, and the door-shaped piece 406 is inserted into the outer end of the protrusion 407; the door-shaped piece 406 usually presses down on the protrusion 407, thereby pressing the upper column 401 on the lower column 405, thereby making the upper column 401 press on the lower column 405. 1 and the lower column 405 form a complete supporting structure to support the disc 501 and the cone 506. When burrs are stuck at the cut after cutting, the telescopic rod 402 drives the door-shaped member 406 to move up and down continuously, and then the upper column 401 swings up and down through the elastic force of the elastic rod 403, thereby driving the disc 501 and the two V-shaped members 502 thereon to swing up and down, thereby causing the left and right parts of the cut pipe to swing up and down, so that the stuck left and right parts of the pipe are quickly separated.
