Description

Technical Field

[0001] This utility model belongs to the field of pipe processing, specifically relating to a pipe cutting device. Background Technology

[0002] Pipe cutting devices are typically used to cut metal or plastic pipes to the appropriate length for repair, replacement, or installation of new parts.

[0003] Existing pipe cutting devices typically consist only of circular saws. When using them, workers need to manually fix the pipes before cutting them. Because a lot of vibration is generated during cutting, the manually fixed pipes may shift during the cutting process, resulting in uneven cuts that may require further grinding before they can be used. Moreover, manually cutting pipes is not only time-consuming and labor-intensive, but may also pose certain safety hazards.

[0004] Therefore, to address the potential safety hazards and uneven pipe cuts that may occur when using the aforementioned pipe cutting devices, a new pipe cutting device has been developed. This device utilizes a pipe-fixing structure consisting of a motor, a mounting base, and a belt to secure the pipe to the top of the housing before cutting, significantly reducing the risk of uneven pipe cuts due to vibration. Furthermore, an automatic cutting structure comprised of an electric cylinder, a movable block, and a circular saw allows the electric cylinder to drive the circular saw downwards to cut the pipe, reducing manual operation and improving safety. Utility Model Content

[0005] In order to overcome the potential safety hazards of pipe cutting devices during use and the problem of uneven pipe cuts after cutting.

A material discharge chute is also provided at the upper end of the housing, located between the leftmost through slot and the central through slot. Fixed blocks are fixed to both ends of the through slots, and drive rollers are rotatably mounted on the inner walls of both ends of the fixed blocks. Three sets of fixed seats are equidistantly distributed at the upper end of the housing, with the front end of each fixed seat corresponding to the rear end of the through slot. Two sets of driven rollers, distributed front and rear, are rotatably mounted on the inner wall of the front end of each fixed seat. A belt is installed at the rear end of each fixed seat. The end passes through two sets of driven rollers and through grooves and is installed on the driving roller. Three sets of first motors are installed on the inner wall of the upper end of the box. The output end of the first motor passes through the right end of the fixed block and is connected to the driving roller. A support frame is installed at the upper end of the box. The support frame corresponds to the material drop chute. The front and rear ends of the support frame are through-cut into grooves. Movable blocks are installed in the grooves. An electric cylinder is installed on the inner wall of the upper end of the support frame. The output end of the electric cylinder is connected to the movable block. A disc cover is installed at the lower end of the movable block. A circular saw is rotatably installed on the inner walls of the left and right ends of the disc cover. A second motor is installed on the right end of the disc cover.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-7This utility model provides an embodiment of a pipe cutting device, including a housing 1 and a support frame 2, as well as a fixed base 4, a belt 5, an electric cylinder 6, and a circular saw 7. The upper end of the housing 1 has three sets of through slots 8 evenly distributed from left to right. A material discharge chute 10 is also opened through the upper end of the housing 1, located between the leftmost through slot 8 and the central through slot 8. Fixed blocks 9 are fixed to both ends of the through slots 8, and active rollers 12 are rotatably mounted on the inner walls of both ends of the fixed blocks 9. Three sets of fixed bases 4 are evenly distributed on the upper end of the housing 1, with the front end of each fixed base 4 corresponding to the rear end of each through slot 8. Two sets of driven rollers 11 are rotatably mounted on the inner wall of the front end of each fixed base 4, distributed front to back. A belt 5 is installed at the rear end of each fixed base 4, with one end of the belt 5 passing through the two sets of driven rollers 11. Roller 11 and through groove 8 are mounted on drive roller 12. Three sets of first motors 13 are equidistantly distributed on the upper inner wall of housing 1. The output end of the first motor 13 passes through the right end of fixed block 9 and is connected to drive roller 12. Support frame 2 is mounted on the upper end of housing 1. Support frame 2 corresponds one-to-one with drop chute 10. Groove 22 is opened through both the front and rear ends of support frame 2. Movable block 15 is set in groove 22. Electric cylinder 6 is mounted on the upper inner wall of support frame 2. The output end of electric cylinder 6 is connected to movable block 15. Disc cover 17 is mounted on the lower end of movable block 15. Circular saw 7 is rotatably mounted on the inner walls of left and right ends of disc cover 17. Second motor 18 is mounted on the right end of disc cover 17. The output end of second motor 18 passes through the right end of disc cover 17 and is connected to the rotating shaft of circular saw 7.

[0018] The output of the first motor 13 drives the drive roller 12 to rotate. The rotating drive roller 12 can wind or loosen the belt 5, so that the belt 5 can fix or loosen the pipe placed on the upper end of the fixed seat 4. Tightening the belt 5 can fix the pipe and prevent uneven cuts caused by vibration during cutting. Then, the output of the second motor 18 drives the circular saw 7 to rotate inside the disc cover 17. The output of the electric cylinder 6 can drive the movable block 15 to move up and down, so that the disc cover 17 drives the circular saw 7 to move up and down to cut the pipe, reducing manual operation by workers and improving safety.

[0019] Please see Figure 4 In this embodiment, an anti-slip pad is installed on the upper end of the fixed seat 4, and the outer wall of the belt 5 is in contact with the outer wall of the driven roller 11. During use, the anti-slip pad can improve the fixing effect on the pipe, and the driven roller 11 can reduce the friction between the fixed seat 4 and the belt 5.

[0020] Please see Figure 6In this embodiment, a limiting post 14 is installed inside the groove 22, and limiting holes 16 are opened through the upper and lower ends of the movable block 15. In use, the movable block 15 can be limited by the limiting post 14 and the limiting hole 16. The outer wall of the movable block 15 is in contact with the inner wall of the groove 22, and the limiting post 14 and the limiting hole 16 are adapted to each other. In use, the stability of the movable block 15 when moving up and down can be improved by the movable block 15 being in contact with the groove 22 and the limiting post 14 being in contact with the limiting hole 16.

[0021] Please see Figure 7 In this embodiment, a protective cover 3 is installed on the upper end of the box 1. The protective cover 3 surrounds the outer wall of the support frame 2. During use, the protective cover 3 can block the debris from the cutting saw and prevent the debris from flying everywhere. A container 20 is provided on the inner wall of the box 1. A box door 21 is hinged to the inner wall of the front end of the box 1. During use, the box door 21 can be used to easily maintain the equipment inside the box 1. The container 20 can carry the debris. A discharge pipe 19 is installed on the inner wall of the discharge chute 10. The opening of the discharge pipe 19 corresponds one-to-one with the opening of the container 20. During use, the debris from the cutting saw can be collected through the discharge pipe 19 and introduced into the container 20 for easy cleaning by workers.

[0022] When working, first place the pipe to be cut through the belt 5 on the upper end of the fixed base 4, and adjust the distance and position of the pipe. Then start the first motor 13. After the output end of the first motor 13 rotates, it drives the belt 5 to tighten and fix the pipe. Then turn off the first motor 13. Next, start the second motor 18. After the output end of the second motor 18 rotates, it drives the circular saw 7 to rotate. Then start the electric cylinder 6. The output end of the electric cylinder 6 presses down, which drives the circular saw 7 to press down and cut the pipe. After the circular saw 7 has finished cutting the pipe, operate the output end of the electric cylinder 6 to rise. Then turn off the electric cylinder 6 and the second motor 18. Start the first motor 13. Operate the output end of the first motor 13 to reverse and loosen the belt 5. Then turn off the first motor 13. Finally, remove the pipe. During cutting, the cut debris can fall into the container 20 through the feed chute 10. The splashing debris can be blocked by the protective cover 3. After the work is completed, the debris on the inner wall of the protective cover 3 and the upper part of the box 1 can be manually swept into the feed chute 10, and the box door 21 can be opened to take out the container 20, clean the debris and put it back.

[0023] Through the above steps, the output end of the first motor 13 can drive the active roller 12 to rotate, so that the belt 5 can fix or loosen the pipe placed on the upper end of the fixed seat 4. Then, the output end of the second motor 18 drives the circular saw 7 to rotate inside the disc cover 17, and the output end of the electric cylinder 6 drives the movable block 15 to move up and down to cut the pipe. This solves the problem that there may be certain safety hazards when using the pipe cutting device and the problem that the pipe cut is uneven after the cutting is completed.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
