[0011] According to the above technical solution, cylinders are fixedly connected to the four sides of the cutting frame, and a clamping strip is fixedly connected to one end of the cylinder away from the cutting frame. The cylinder can quickly clamp the pipe through the clamping strip to ensure good stability of the pipe during the cutting process.

[0013] According to the above technical solution, two of the movable gear and the driven gear are provided, and the two movable gears and the driven gear are respectively distributed at the four corners of the extension frame. During the rotation process, the movable gear and the driven gear cooperate with the racks on the first placement frame and the second placement frame, so that the first placement frame and the second placement frame can slide in the slide grooves on both sides of the extension frame to adapt to the cutting of pipes of different lengths.

[0014] According to the above technical solution, a third motor is fixedly connected to the movable gear at the bottom of the fixed plate.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] 1. The present invention is provided with a cutting mechanism. When the pipe is moved into the cutting frame, the cylinder works to push the clamping strip toward the pipe to fix the pipe. When the first motor starts to drive the lead screw to rotate, the sliding plate can achieve stable forward and backward movement on the sliding rod under the cooperation of the ball nut pair, thereby driving the cutting disc to approach the pipe. When the cutting disc approaches the pipe, the second motor is started, which can drive the cutting disc to rotate at high speed and quickly cut the entire pipe. At the same time, because the cylinder clamps both sides of the cutting position of the pipe through the clamping strip, the stability of the pipe incision during the cutting process can be guaranteed, which effectively solves the problem that the stability of the cutting part cannot be guaranteed during the cutting process, which easily causes the cutting part to deviate and cause the incision to be uneven, and is inconvenient for later installation.

[0019] 2. The present invention is provided with an extension mechanism. When the length of the entire cutting device needs to be adjusted for cutting the pipe, the third motor is started to drive the movable gear to rotate. During the rotation of the movable gear, the slave gear cooperates with the first pulley, the second pulley and the belt to achieve a synchronous rotation effect with the movable gear. At this time, the first placement rack and the second placement rack cooperate with the racks of the slide groove in the extension rack to achieve the first placement rack and the second placement rack sliding into the slide groove or sliding out of the slide groove, thereby quickly achieving the length adjustment of the entire device, so that the entire device can adapt to the cutting of pipes of different lengths.

[0020] 3. The present invention is provided with a placement mechanism. When the pipe is placed on the first placement rack, the inclined placement wheels can form a good supporting effect on the pipe. At the same time, the fourth motor is started, which can drive one of the placement wheels to rotate. The rotating placement wheel can cause the pipe on the first placement rack to generate a force to move toward the cutting rack, thereby further facilitating the cutting of the pipe. At the same time, when the cut pipe is moved to the second placement rack, the fourth motor on the second placement rack is started, which can drive the pipe to separate from the entire cutting device, further realizing a good cutting effect of the entire device.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The present invention provides the following technical solutions: Example 1

[0031] See also Figure 1-2 and Figure 6 A cutting device for pipe production includes an extension mechanism 3, a placement mechanism 5 is provided on both sides of the extension mechanism 3, a support rod 1 is fixedly connected to the bottom of the placement mechanism 5 and the extension mechanism 3, a roller 2 is rotatably connected to the bottom end of the support rod 1, and a cutting mechanism 4 is fixedly connected to the middle of the top of the extension mechanism 3;

[0032] The cutting mechanism 4 includes a cutting frame 41, in the middle of the cutting frame 41, a lead screw 451 is rotatably connected near the top, and the lead screw 451 is threadedly connected to a ball nut pair 43 near the rear end, and the bottom of the ball nut pair 43 is fixedly connected to a sliding plate 441, and the four corners of the top of the sliding plate 441 are fixedly connected to sliding blocks 44, and the middle of the sliding block 44 is slidably connected to a sliding rod 42, and the two ends of the sliding rod 42 are fixedly connected to the two sides of the support frame, and the middle of the bottom of the sliding plate 441 is fixedly connected to a fixed block 47, and the middle of the fixed block 47 is rotatably connected to a cutting blade 48, and the right side of the fixed block 47 is fixedly connected to the corresponding cutting blade 48. By providing the cutting mechanism 4, when the pipe moves into the cutting frame 41, the cylinder 46 works to clamp it. The strip 461 is pushed toward the pipeline to fix the pipeline. When the first motor 45 starts to drive the lead screw 451 to rotate, the sliding plate 441 can achieve stable forward and backward movement on the sliding rod 42 with the cooperation of the ball nut pair 43, thereby driving the cutting disc 48 to approach the pipeline. When the cutting disc 48 approaches the pipeline, the second motor 49 is started to drive the cutting disc 48 to rotate at high speed, thereby achieving rapid cutting of the entire pipeline. At the same time, because the cylinder 46 clamps both sides of the cutting pipeline position through the clamping strip 461, it can ensure the stability of the pipeline incision during the cutting process, effectively solving the problem that the stability of the cutting part cannot be guaranteed during the cutting process, which easily causes the cutting part to deviate and cause the incision to be uneven, which is inconvenient for later installation.

[0033] A sliding sleeve is fixedly connected in the middle of the sliding block 44, and the sliding block 44 is slidably connected to the sliding rod 42 through the sliding sleeve. The sliding block 44 can increase the contact area with the sliding rod 42 through the sliding sleeve in the middle to ensure that the entire sliding plate 441 can move back and forth stably on the sliding rod 42 in the later stage.

[0034] The first motor 45 is fixedly connected to the lead screw 451 corresponding to the rear side of the cutting frame 41. The first motor 45 is fixedly connected to the lead screw 451 through an output shaft. The second motor 49 is fixedly connected to the cutting blade 48 through an output shaft. The first motor 45 applies sufficient power to the lead screw 451. The lead screw 451 cooperates with the ball nut pair 43 to provide power for the movement of the sliding plate 441. The second motor 49 can apply sufficient power to the cutting blade 48, thereby realizing rapid cutting of the pipeline.

[0035] Cylinders 46 are fixedly connected to the four sides of the cutting frame 41, and a clamping strip 461 is fixedly connected to the end of the cylinder 46 away from the cutting frame 41. The cylinder 46 can cooperate with the clamping strip 461 to quickly clamp the pipe, ensuring that the pipe has good stability during the cutting process. Example 2

[0036] See also Figure 1-5, and on the basis of the first embodiment, the extension mechanism 3 is further obtained to include an extension frame 32, with slide grooves 38 on both sides of the extension frame 32, and a fixed plate 34 is fixedly connected to the corresponding slide grooves 38 on the inner side of the extension frame 32, a movable gear 37 is rotatably connected in the middle of the front fixed plate 34 in the extension frame 32, and a slave gear 39 is rotatably connected in the middle of the rear fixed plate 34 in the extension frame 32, and a second pulley 351 and a first pulley 35 are fixedly connected to the top of the movable gear 37 and the slave gear 39 respectively, a belt 36 is provided between the first pulley 35 and the second pulley 351, and the first pulley 35 is connected to the second pulley 351 through the belt 36, and the movable gear 37 and the slave gear 39 are meshed with a rack 31 on the outer side. There is an extension mechanism 3. When the length of the entire cutting device needs to be adjusted for cutting the pipe, the third motor 33 is started at this time, which can drive the movable gear 37 to rotate. During the rotation of the movable gear 37, the slave gear 39 cooperates with the first pulley 35, the second pulley 351 and the belt 36 to achieve the effect of synchronous rotation with the movable gear 37. At this time, the first placement rack 51 and the second placement rack 56 cooperate with the rack 31 of the slide groove 38 in the extension rack 32, so that the first placement rack 51 and the second placement rack 56 can slide into the slide groove 38 or slide out of the slide groove 38, thereby quickly adjusting the length of the entire device, so that the entire device can adapt to pipe cutting of different lengths.

[0037] There are two movable gears 37 and two driven gears 39, which are respectively distributed at the four corners of the extension frame 32. During the rotation process, the movable gears 37 and the driven gears 39 cooperate with the racks 31 on the first placement frame 51 and the second placement frame 56, so that the first placement frame 51 and the second placement frame 56 can slide in the slide grooves 38 on both sides of the extension frame 32 to adapt to the cutting of pipes of different lengths.

[0038] The bottom of the fixed plate 34 is fixedly connected to the movable gear 37 with the third motor 33. The third motor 33 is fixedly connected to the movable gear 37 via an output shaft. The third motor 33 applies sufficient power to the movable gear 37. This enables the first placement rack 51 and the second placement rack 56 to slide easily, further facilitating the cutting of different pipes in the later stage. Example 3

[0039] See also Figure 1-5, and on the basis of embodiment 3, the placing mechanism 5 is further obtained to include a first placing rack 51 and a second placing rack 56, the first placing rack 51 and the second placing rack 56 are slidably connected to the slide grooves 38 on both sides of the extension rack 32, the top of the first placing rack 51 and the second placing rack 56 are fixedly connected to the first support block 52, the top of the first support block 52 is fixedly connected to the second support block 53, and the middle of the top of the second support block 53 is rotatably connected to the placing wheel 54. By providing the placing mechanism 5, when the pipe is placed on the first placing rack 51, the inclined placing wheel 54 can form a good supporting effect on the pipe. At the same time, the fourth motor 55 is started, which can drive one of the placing wheels 54 to rotate. The rotating placing wheel 54 can make the pipe generate a force on the first placing rack 51 to move toward the cutting rack 41, thereby further facilitating the cutting of the pipe. At the same time, when the cut pipe moves to the second placing rack 56, the fourth motor 55 on the second placing rack 56 is started, which can drive the pipe to separate from the entire cutting device, further realizing that the entire device has a good cutting effect.

[0040] The first placement rack 51 and the second placement rack 56 are fixedly connected to the outer side of the rack 31 in the slide groove 38, and the fourth motor 55 is fixedly connected to the corresponding placement wheel 54 on the outer side of the second support block 53. The fourth motor 55 is fixedly connected to the placement wheel 54 through the output shaft. The fourth motor 55 is set on the first placement rack 51 and the second placement rack 56. The fourth motor 55 is set near the middle of the first placement rack 51, and the fourth motor 55 is set near the left side of the second placement rack 56. It can ensure that the placement wheel 54 is driven to rotate by the fourth motor 55 during the cutting process in the later stage, thereby realizing the cutting movement of the pipeline in sequence, which further facilitates the later pipeline cutting.

[0041] During use, when the pipe moves into the cutting frame 41, the cylinder 46 works to push the clamping strip 461 toward the pipe to fix the pipe. When the first motor 45 starts to drive the screw 451 to rotate, the ball nut pair 43 cooperates to enable the sliding plate 441 to achieve stable forward and backward movement on the sliding rod 42, thereby driving the cutting disc 48 to approach the pipe. When the cutting disc 48 approaches the pipe, the second motor 49 starts to drive the cutting disc 48 to rotate at high speed, thereby achieving rapid cutting of the entire pipe. At the same time, because the cylinder 46 clamps both sides of the cutting pipe position through the clamping strip 461, it can ensure the stability of the pipe incision during the cutting process, effectively solving the problem that the stability of the cutting part cannot be guaranteed during the cutting process, which easily causes the cutting part to deviate and cause the incision to be uneven, which is inconvenient for later installation.

[0042] When the length of the entire cutting device needs to be adjusted for cutting the pipe, the third motor 33 is started to drive the movable gear 37 to rotate. During the rotation of the movable gear 37, the slave gear 39 cooperates with the first pulley 35, the second pulley 351 and the belt 36 to achieve synchronous rotation with the movable gear 37. At this time, the first placement rack 51 and the second placement rack 56 cooperate with the rack 31 of the slide groove 38 in the extension rack 32, so that the first placement rack 51 and the second placement rack 56 can slide into the slide groove 38 or slide out of the slide groove 38, thereby quickly adjusting the length of the entire device and making the entire device adaptable to pipe cutting of different lengths.

[0043] When the pipe is placed on the first placement rack 51, the inclined placement wheel 54 can provide a good supporting effect for the pipe. At the same time, the fourth motor 55 is started, which can drive one of the placement wheels 54 to rotate. The rotating placement wheel 54 can cause the pipe on the first placement rack 51 to generate a force to move toward the cutting rack 41, thereby further facilitating the cutting of the pipe. At the same time, when the cut pipe moves to the second placement rack 56, the fourth motor 55 on the second placement rack 56 is started, which can drive the pipe to separate from the entire cutting device, further realizing a good cutting effect of the entire device.
