Description

[0001] This case is a divisional application. The original application was entitled "A Pipe Cutting Machine". The original application was filed on August 29, 2022, and the original application number was 202211036517.7. Technical Field

[0002] This invention relates to the field of pipe cutting equipment, and more particularly to a cutting system for building pipes. Background Technology

[0003] In the production of templates, a large number of pipes of specific lengths are often required, so the pipes need to be cut. Usually, a pipe cutting system is used to process the pipes. However, after the pipes are cut by the existing pipe cutting system, the cut pipes need to be collected and sorted manually. The whole process is time-consuming, labor-intensive, and has certain dangers. For example, hands can be easily scratched by the burrs of the pipes during the manual collection process.

[0004] Therefore, it is essential to provide a device that can save manpower and, to some extent, replace manual labor in effectively storing cut pipes during use. Summary of the Invention

The fourth motor drives the lead screw C to rotate, which enables the circular saw teeth to move up and down, thereby cutting the steel pipe.

[0045] Working principle:

[0046] 1. Debugging: First, set the working angle of the stepper motor to 120 degrees, and make the position of the clamping groove flush with the position of the steel pipe after it is clamped on the worktable, so that the steel pipe can smoothly enter the clamping groove. Adjust one side of the vertical rod to be exactly below the clamping groove, and make the guide part completely in the first T-shaped slide groove of the vertical rod above the electric telescopic rod A. Then, connect the sliding sleeve with the fixed sleeve on the first bearing, and then start the electric telescopic rod A so that the guide part at the top is in the second T-shaped slide groove.

[0047] 2. Work:

[0048] The first step is to place the steel pipe to be cut onto the workbench, press it against the baffle, and then clamp it with the clamping mechanism.

[0049] The second step is to start the stepper motor to make the conveyor mechanism rotate. At this time, the clamping groove above the electric telescopic rod A rotates 120 degrees and reaches above the belt.

[0050] The third step involves adjusting the position of the circular saw teeth according to the required length of the steel pipe to be cut using the second motor, then starting the circular saw teeth to rotate using the third motor, and then moving the circular saw teeth downwards using the fourth motor to cut. After cutting, the circular saw teeth are raised.

[0051] Fourth step, rotate the rotating handle to move the rollers on both sides to the middle and clamp the cut steel pipe. At the same time, the baffle moves down. After the steel pipe is clamped, start the first motor to rotate the rollers on the corresponding side and drive the steel pipe to move towards the clamping groove. At this time, start the fifth motor to rotate the belt. When the steel pipe reaches the belt, the steel pipe will continue to be moved forward until it is inserted into the guide bar.

[0052] Fifth step, start the stepper motor to make the conveying mechanism rotate 120 degrees. At this time, the clamp with the steel pipe is exactly above the storage box. Under the action of gravity, the steel pipe, together with the guide part, falls into the storage box. Repeat the above steps until the storage box is full of steel pipes. At this time, all the guide parts have also fallen into the storage box.

[0053] Step 6: Remove the storage box filled with the steel pipes, then slide the sector block and insert the sliding rod into the insertion hole of the sliding sleeve. Next, pull the handle to engage the sliding sleeve with the fixed sleeve on the second bearing. Then slide the sector block away and start the stepper motor to rotate the guide mechanism 120 degrees. This will rotate the vertical rod filled with the guide part above the electric telescopic rod A. Finally, place the empty storage box in the storage position and start a new round of operations.

[0054] The beneficial effects of this invention are as follows: the device has a simple structure and is easy to operate, realizing accurate cutting of steel pipes of different required lengths, and at the same time, it performs semi-automatic storage of the cut steel pipes, saving manpower and improving work efficiency.

[0111] Working principle:

[0112] 1. Debugging: First, set the working angle of the stepper motor 68 to 120 degrees, and make the position of the clamping groove 59 flush with the position of the steel pipe after clamping on the workbench 1, so that the steel pipe can smoothly enter the clamping groove 59. Adjust one side of the vertical rod 63 to be exactly below the clamping groove 59, and make the guide part 8 completely in the first T-shaped slide groove 62 of the vertical rod 63 above the electric telescopic rod A69. Then, connect the sliding sleeve 51 with the fixed sleeve 83 on the first bearing 47, and then start the electric telescopic rod A69 so that the top guide part 8 is in the second T-shaped slide groove 60.

[0113] 2. Work:

[0114] The first step is to place the steel pipe to be cut on the workbench 1, press it against the baffle 19, and then clamp it with the clamping mechanism 2.

[0115] The second step is to start the stepper motor 68 to make the transmission mechanism 6 rotate. At this time, the clamping groove 59 above the electric telescopic rod A69 rotates 120 degrees and reaches above the belt 48.

[0116] The third step is to adjust the position of the circular saw teeth 15 according to the length requirement of the steel pipe to be cut by the second motor 26, then start the circular saw teeth 15 to rotate by the third motor, and then move the circular saw teeth 15 downward by the fourth motor 21 to cut. After cutting, the circular saw teeth 15 are raised.

[0117] Fourth step, rotate the handle 22 to move the rollers 30 on both sides towards the middle to clamp the cut steel pipe. At the same time, the baffle 19 moves down. After the steel pipe is clamped, start the first motor 36 to rotate the rollers 30 on the corresponding side, which will drive the steel pipe to move towards the clamping groove 59. At this time, start the fifth motor 67 to rotate the belt 48. When the steel pipe reaches the belt 48, the steel pipe will continue to be moved forward until it is inserted into the guide bar 81.

[0118] Fifth step, start the stepper motor 68 to make the conveying mechanism 6 rotate 120 degrees. At this time, the clamping groove 59 with steel pipe is exactly above the storage box 10. Under the action of gravity, the steel pipe, together with the guide part 8, falls into the storage box 10. Repeat the above steps until the storage box 10 is full of steel pipe. At this time, all the guide parts 8 also fall into the storage box 10.

[0119] Step 6: Remove the storage box 10 filled with steel pipes, then slide the sector block 9 and insert the slide rod 78 into the insertion hole 64 of the sliding sleeve 51. Then pull the handle 76 to engage the sliding sleeve 51 with the fixed sleeve 83 on the second bearing 55. Next, slide the sector block 9 away and start the stepper motor 68 to rotate the guide mechanism 7 120 degrees. This will rotate the vertical rod 63 filled with the guide part 8 to the top of the electric telescopic rod A69. Finally, place the empty storage box 10 in the storage position and start a new round of operations.
