Description

Technical Field

[0001] This utility model relates to the field of metal round tube processing technology, and in particular to a cutting device for metal round tube processing. Background Technology

[0002] Metal tubes are hollow metal materials with a circular cross-section and a length much greater than their diameter. They are widely used in construction, machinery, automobiles, energy, furniture, and piping systems.

[0003] In the metal processing industry, cutting metal round tubes is a common processing procedure. Traditional metal round tube cutting devices have many shortcomings. They require repeated rotation of the round tube to adjust the cutting position. On the one hand, frequent rotation and repositioning of the round tube consume a lot of time, resulting in a longer processing cycle. Especially in mass production, the repetitive manual adjustment will significantly reduce the overall production efficiency. On the other hand, each time the round tube is rotated, small errors accumulate, causing the cut position to shift, the angle to tilt, or the length to be uneven, which affects the quality of subsequent assembly or welding.

[0004] To address the above issues, we have developed a cutting device for processing metal round tubes. Utility Model Content

[0005] This utility model discloses a cutting device for processing metal round tubes, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting device for processing metal round tubes includes an operating table, two lower clamping plates, and two upper clamping plates. One of the lower clamping plates is fixedly connected to one end of the top of the operating table and has an L-shaped plate fixedly connected to one side. The other lower clamping plate is slidably connected to the top of the operating table and has a vertical plate fixedly connected to its top. A first cylinder is fixedly connected to the top of the L-shaped plate, and its output end passes through the L-shaped plate and is fixedly connected to the top of one of the upper clamping plates. The other upper clamping plate is slidably connected to the outside of the vertical plate and has two connecting rods fixedly connected to one side. The connecting rods pass through one of the upper clamping plates. Each upper clamping plate is used in conjunction with a corresponding lower clamping plate. Rollers are rotatably connected to both sides of the top of the lower clamping plate and both sides of the bottom of the upper clamping plate. A fixing plate is fixedly connected to one end of the top of the operating table. A first motor is fixedly connected to one side of the fixing plate. The output shaft of the first motor passes through the fixing plate and is fixedly connected to a rotating abutment.

[0008] The metal tube is placed on two lower clamping plates. The first cylinder is started to drive the upper clamping plate to press down, which in turn clamps the tube with the lower clamping plates. The first motor is started to rotate the abutment plate and rotate the tube. With the assistance of rollers, the tube can rotate precisely, ensuring that the cutting position and angle are more accurate.

[0009] In a preferred embodiment, a movable frame is slidably connected between the outer sides of the two connecting rods. A second cylinder is fixedly connected to the top of the movable frame. The output end of the second cylinder extends into the interior of the movable frame and is fixedly connected to a support frame. A second motor is fixedly connected to one side of the support frame. The output shaft of the second motor extends into the interior of the support frame and is fixedly connected to a cutting blade.

[0010] After the round tube is positioned, the position of the movable bracket on the connecting rod is adjusted to align with the cutting point. The second cylinder is then activated to lower the cutting blade close to the round tube. The second motor is then activated to drive the cutting blade to rotate at high speed, thus completing the cutting of the round tube.

[0011] In a preferred embodiment, threaded holes are provided at equal intervals on the opposite sides of the two connecting rods, and adjusting screws are provided on both sides of the movable frame, with the adjusting screws threadedly connected to the corresponding threaded holes.

[0012] For round tubes requiring different lengths, loosen the adjusting screw, move the movable frame along the connecting rod to adjust the position of the cutting blade, and then tighten the adjusting screw to secure it, ensuring cutting accuracy.

[0013] In a preferred embodiment, the operating table has a sliding groove inside, a threaded rod is rotatably connected inside the sliding groove, a sliding block is threadedly connected to the outside of the threaded rod, the top of the sliding block is fixedly connected to the bottom of the lower clamping plate slidably connected to the top of the operating table, and one end of the threaded rod extends to the outside of the operating table and is fixedly connected to a handwheel.

[0014] Rotating the handwheel drives the threaded rod to rotate, causing the sliding block to move within the sliding groove, thereby adjusting the position of the lower clamping plate of the sliding connection to accommodate the clamping and fixing of metal round tubes of different lengths.

[0015] In a preferred embodiment, a first limiting rod is fixedly connected to the top of one of the upper clamping plates and to both sides of the first cylinder, and the first limiting rod is slidably connected to the L-shaped plate. A second limiting rod is fixedly connected to the top of the support frame and to both sides of the second cylinder, and the second limiting rod is slidably connected to the movable frame.

[0016] When the first cylinder drives the upper clamping plate to press down, the first limiting rod slides inside the L-shaped plate to ensure that the pressing process is smooth and does not deviate. When the second cylinder pushes the support frame, the second limiting rod slides inside the movable frame to ensure that the cutting blade descends vertically and improves the cutting accuracy.

[0017] In a preferred embodiment, the top of the operating table and both sides of the sliding groove are fixedly connected to limit slide rails, and the lower clamping plates slidably connected to the top of the operating table are slidably connected to the limit slide rails.

[0018] When adjusting the position of the lower clamping plate, the limiting slide rail limits and guides it, so that it slides smoothly along a straight line, avoiding deviation that would affect the clamping and cutting effect of the round tube.

[0019] In a preferred embodiment, the first cylinder, the first motor, the second cylinder, and the second motor are all electrically connected to an external control device.

[0020] By pre-setting the cutting program through external control equipment, after the equipment is started, the first cylinder is automatically controlled to clamp the round tube, the first motor rotates the round tube, and the second cylinder and the second motor complete the cutting action, thus realizing the automated operation of cutting metal round tubes.

[0021] The cutting device for processing metal round tubes provided by this utility model has the following advantages:

[0022] This invention enables the automatic rotation of the metal tube during cutting, eliminating the need for manual adjustment of the cutting position. This reduces the need for manual intervention, significantly improving the speed and efficiency of cutting. Operators no longer need to manually adjust the tube's position, saving considerable time and labor. Furthermore, it allows for precise control of the tube's rotation angle and speed, ensuring more accurate cutting position and angle, thereby improving product processing precision and consistency. Compared to traditional devices, this invention greatly enhances operational quality and efficiency. Attached Figure Description

[0033] In this embodiment: the metal tube is placed on two lower clamping plates 2, the first cylinder 8 is started to drive the upper clamping plate 3 to press down, and the tube is clamped by the lower clamping plates 2. The first motor 10 is started, and the rotating plate 11 rotates the tube. With the assistance of the roller 4, the tube can rotate accurately, ensuring that the cutting position and angle are more accurate.

[0034] In a preferred embodiment, a movable frame 12 is slidably connected between the outer sides of the two connecting rods 6.

[0035] In this embodiment: after the round tube is positioned, the position of the movable frame 12 on the connecting rod 6 is adjusted to align with the cutting point. The second cylinder 13 is started to lower the cutting blade 16 close to the round tube.

[0036] In a preferred embodiment, threaded holes 18 are provided at equal intervals on the opposite sides of the two connecting rods 6, and adjusting screws 17 are provided on both sides of the movable frame 12, with the adjusting screws 17 threadedly connected to the corresponding threaded holes 18.

[0037] In this embodiment: For round tubes with different length requirements, loosen the adjusting screw 17, move the movable frame 12 along the connecting rod 6 to adjust the position of the cutting blade 16, and then tighten the adjusting screw 17 to fix it to ensure cutting accuracy.

[0038] In a preferred embodiment, the operating table 1 has a sliding groove 19 inside, a threaded rod 20 is rotatably connected inside the sliding groove 19, a sliding block 21 is threadedly connected to the outside of the threaded rod 20, the top of the sliding block 21 is fixedly connected to the bottom of the lower clamping plate 2 which is slidably connected to the top of the operating table 1, and one end of the threaded rod 20 extends to the outside of the operating table 1 and is fixedly connected to a handwheel 22.

[0039] In this embodiment, rotating the handwheel 22 drives the threaded rod 20 to rotate, causing the sliding block 21 to move within the sliding groove 19, thereby adjusting the position of the lower clamping plate 2 of the sliding connection to adapt to the clamping and fixing of metal round tubes of different lengths.

[0040] In a preferred embodiment, a first limiting rod 23 is fixedly connected to the top of one of the upper clamping plates 3 and to both sides of the first cylinder 8.

The second limiting rod 24 is slidably connected to the movable frame 12.

[0041] In this embodiment: when the first cylinder 8 drives the upper clamping plate 3 to press down, the first limiting rod 23 slides within the L-shaped plate 7 to ensure that the pressing process is smooth and does not deviate. When the second cylinder 13 pushes the support frame 14, the second limiting rod 24 slides within the movable frame 12 to ensure that the cutting blade 16 descends vertically and improves the cutting accuracy.

[0042] In a preferred embodiment, the top of the operating table 1 and both sides of the sliding groove 19 are fixedly connected to the limiting slide rails 25, and the lower clamping plates 2 slidably connected to the top of the operating table 1 are slidably connected to the limiting slide rails 25.

[0044] In a preferred embodiment, the first cylinder 8, the first motor 10, the second cylinder 13, and the second motor 15 are all electrically connected to an external control device.

[0045] In this embodiment, the cutting program is preset by an external control device. After the device is started, the first cylinder 8 clamps the round tube, the first motor 10 rotates the round tube, and the second cylinder 13 and the second motor 15 complete the cutting action, thereby realizing the automated operation of cutting metal round tubes.

[0046] Working principle: In use, the metal tube is placed on the two lower clamping plates 2. The first cylinder 8 drives the upper clamping plate 3 to move downward, cooperating with the lower clamping plates 2 to clamp the metal tube. The roller 4 ensures the smooth rotation of the metal tube during clamping. The handwheel 22 drives the threaded rod 20 to rotate, and the sliding block 21 slides in the sliding groove 19, pushing the lower clamping plate 2 to move and adjust the clamping position. The first motor 10 drives the rotating abutment plate 11 to rotate, pushing the metal tube to the cut-off position. The second cylinder 13 drives the support frame 14 downward. The second motor 15 drives the cutting blade 16 to rotate, cutting the metal tube. The adjusting screw 17 engages with the threaded hole 18 to adjust the position of the movable frame 12, ensuring precise alignment between the cutting blade 16 and the metal tube. The first limiting rod 23 and the second limiting rod 24 respectively limit the movement range of the upper clamping plate 3 and the support frame 14, ensuring the stability of clamping and cutting. The limiting slide rail 25 ensures that the slidingly connected lower clamping plate 2 remains stable during movement. This achieves efficient and precise cutting of the metal tube, ensuring processing quality and production efficiency.
