Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and more specifically, relates to a pipe cutting device for building engineering. Background Technology

[0002] With the development of society, more and more buildings are being constructed, and pipes, as a common building material in construction projects, are being used in increasing quantities. Before using pipes, they need to be cut into small sections of fixed length. Traditional techniques often use manual cutting, which is slow and has poor cutting results, and it is difficult to ensure that the cut lengths are consistent.

[0003] Chinese patent with authorization announcement number "CN114083048B" discloses a continuous pipe cutting mechanism for construction engineering, including a mounting frame and a rotating shaft. A first mounting ring and a second mounting ring are fixed to the circumference of the rotating shaft through connecting rods. A socket is fixed to the circumference of the second mounting ring. An adjusting ring is installed on the first mounting ring, and a stop block is fixed on the adjusting ring. Multiple pipes are placed on the mounting frame, which facilitates the adjustment of the cutting position of the pipes and is conducive to cutting into pipes of different lengths. It can cut multiple pipes continuously at the same time, with a high degree of automation, which greatly improves the cutting volume of pipes.

[0004] In subsequent use, the device also has the following problems: the pipe can only be inserted into the socket from the side of the cutting equipment, making it difficult to increase the speed. Furthermore, the pipe inserted into the socket is difficult to fix, which causes the pipe to vibrate and shift during the cutting process, resulting in more burrs on the cut surface and poor cutting quality.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 17As shown, a pipe cutting device for construction engineering includes a housing 1. A pipe storage chamber 101 is fixedly installed on the side of the housing 1. Multiple sets of steel pipes 8 are installed inside the pipe storage chamber 101. The steel pipes 8 to be cut are uniformly placed inside the pipe storage chamber 101. A pipe pushing assembly 2 is fixedly installed on the outer wall of the pipe storage chamber 101. The pipe pushing assembly 2 includes an electric push rod 201, which is fixedly connected to the outer wall of the pipe storage chamber 101. A push block 202 is fixedly connected to one end of the electric push rod 201. The push block 202 is slidably connected to the inner wall of the pipe storage chamber 101. The pipe storage chamber 101 is generally L-shaped. The vertical part is used to store the pipes to be processed, and the horizontal part is used to push the pipes into the clamping mechanism 5 individually. With the rotation of the drive motor 301 and the drive motor 401, the pipe fixing groove 501B of the clamping mechanism 5 is aligned with the horizontal part of the pipe storage compartment 101. The electric push rod 201 extends and drives the push block 202 to push the bottom steel pipe 8 into the pipe fixing groove 501B, and is grabbed and fixed by the claw 504 for subsequent cutting operations. Then, the electric push rod 201 drives the push block 202 to retract, and the steel pipe 8 continues to fall, waiting for the next push into the housing 1.

[0037] The bottom of the housing 1 is fixedly provided with a tube ejection port 102, and multiple sets of guide rails 103 are fixedly provided on the inner wall of the housing 1. Multiple sets of tube ejection claws 7 are fixedly connected to the bottom of the inner wall of the housing 1. The tube ejection claws 7 cooperate with the tube ejection port 102, so that the steel pipe 8 after the cutting operation falls from the tube ejection port 102. A rotating cylinder 3 is installed inside the housing 1. The steel pipe 8 enters the rotating cylinder 3 radially. Compared with the axial direction, its speed is faster, which greatly improves the production efficiency. The steel pipe 8 is placed in a horizontal position in the rotating cylinder 3. During the rotation of the rotating cylinder 3, the cutting operation is completed at the same time. The cut steel pipe 8 falls from the tube ejection port 102 and is collected. A clamping mechanism 5 is rotatably connected to the rotating cylinder 3. After the steel pipe 8 is pushed radially into the housing 1, it is clamped and fixed by the clamping mechanism 5 to prevent the vibration generated during the cutting process from affecting the cutting quality. While fixing the steel pipe 8, the clamping mechanism 5 also generates its own... The rotation of the cylinder 3 causes the steel pipe 8 to rotate, allowing the pipe wall to come into contact with the cutting mechanism 6. This allows the cutting tool 605B to gradually cut from the outer wall of the steel pipe 8 towards the center. Compared to the traditional method of directly cutting the pipe from one end to the other, this method of circling the steel pipe 8 effectively reduces the number of burrs on the cut surface, greatly improving cutting quality. Furthermore, when dealing with thin-walled steel pipes 8, this circling cutting method effectively avoids deformation. The rotating cylinder 3 contains a rotating assembly 4, which controls the rotation of the clamping mechanism 5. The cutting mechanism 6 is slidably connected to the outer wall of the rotating cylinder 3. The cutting mechanism 6 is used to cut the steel pipe 8 into segments. By sliding the cutting mechanism 6 and adjusting its position on the outer wall of the rotating cylinder 3, the length of each segment of the steel pipe 8 after cutting can be changed.

[0038] like Figure 3 and Figure 5 As shown, the rotating cylinder 3 includes multiple sets of rotating cylinders 302. Multiple sets of mounting grooves 302A are fixedly provided on the rotating cylinders 302. Each mounting groove 302A has an inner wall with a slot 302B. Rotating pipes 303 are fixedly connected between the multiple sets of rotating cylinders 302. Straight rails 303A are fixedly provided on the rotating pipes 303. A drive motor 301 is fixedly connected to the left side wall of the housing 1. The output shaft of the drive motor 301 extends into the housing 1 and is fixedly connected to the rotating cylinders 302. A through hole 304 is fixedly provided at the center of the side wall of the rightmost rotating cylinder 302. Driven by the drive motor 301, the rotating cylinder 3 rotates within the housing 1, causing the clamping mechanism 5, mounted on the mounting groove 302A, to revolve around the housing 1. During rotation, it completes a series of actions, including the entry, fixing, cutting, and exiting of the steel pipe 8, greatly improving cutting efficiency.

[0039] like Figure 6 , Figure 7 and Figure 8 As shown, the clamping mechanism 5 includes a mounting cylinder 501, the outer wall of which is rotatably connected to the mounting groove 302A. A fixing tooth 501A is fixedly provided in the middle of the outer wall of the mounting cylinder 501, which cooperates with the groove 302B. Thus, the mounting cylinder 501 can rotate directionally on the mounting groove 302A with the cooperation of the rotating component 4. A pipe-fixing groove 501B is fixedly provided on the mounting cylinder 501, and the steel pipe 8 is placed and fixed at the bottom of the pipe-fixing groove 501B. A latch 504 is rotatably connected inside the mounting cylinder 501, which cooperates with the pipe-fixing groove 501B. A pressing block is fixedly provided at the top front end of the latch 504. 504A, a small compression spring 506 is fixedly connected to the bottom rear end of the latch 504. The other end of the small compression spring 506 is fixedly connected to the mounting cylinder 501. The front end of the latch 504 is a triangular block structure. Under the elastic force of the small compression spring 506, the latch 504 will block the entrance of the solid pipe groove 501B. When the steel pipe 8 is pushed into the solid pipe groove 501B, it will also come into contact with the triangular block structure, squeezing the front end of the latch 504. The small compression spring 506 is compressed, the latch 504 is lifted, and the steel pipe 8 enters the innermost part of the solid pipe groove 501B. At the same time, the latch 504 rebounds under the action of the small compression spring 506 to press the steel pipe 8, so that the steel pipe 8 cannot easily slip out of the solid pipe groove 501B.

[0040] The bottom of the latch 504 is equipped with a pusher 505. The middle part of the pusher 505 is rotatably connected to the mounting cylinder 501. The front end of the pusher 505 engages with the pipe-fixing groove 501B. A large compression spring 507 is fixedly connected to one side of the rear end of the pusher 505. The other end of the large compression spring 507 is fixedly connected to the mounting cylinder 501. The front end of the pusher 505 is located at the innermost side of the pipe-fixing groove 501B. Ideally, the pusher 505 will push the steel pipe 8 out of the pipe-fixing groove 501B under the elastic force of the large compression spring 507. The elastic force of spring 507 is greater than that of small compression spring 506. Therefore, under normal conditions without external interference, the steel pipe 8 will be easily pushed out of the fixed pipe groove 501B by pusher 505 and forcibly separated from the latch 504. A second pressing block 505A is fixedly provided on the other side of the rear end of pusher 505. Adjusting rod 1 502 and adjusting rod 2 503 are slidably connected to the side wall of mounting cylinder 501. Adjusting rod 1 502 cooperates with pressing block 1 504A, and adjusting rod 2 503 cooperates with pressing block 2 505A. Both pressing block 2 505A and pressing block 1 504A have smooth structures to reduce friction between the parts in contact with them.

[0041] like Figure 9 and Figure 10As shown, an adjusting disc 508 is provided on one side of the mounting cylinder 501. The adjusting disc 508 is in contact with the guide rail 103. Therefore, the adjusting disc 508 will move to a certain extent under the control of the guide rail 103, allowing the adjusting disc 508 to move away from or closer to the side wall of the mounting cylinder 501, thereby adjusting the state of the pusher 505 and the latch 504, realizing actions such as blocking the steel pipe 8, fixing the steel pipe 8, and popping out the steel pipe 8. An opening 508A is fixedly opened on the adjusting disc 508, which cooperates with the pipe fixing groove 501B to avoid interference between the adjusting disc 508 and the steel pipe 8. Two sets of pressure rods 508B are fixedly connected to the adjusting disc 508. A transition rod 502B is provided in the middle of the adjusting pressure rod 502. A thin rod 502A is fixedly provided on the left side of the transition rod 502B, and a thick rod 502C is fixedly provided on the right side of the transition rod 502B. When the thin rod 502A and the extrusion rod 502C are connected, the adjustment rod 508B will move away from or closer to the side wall of the mounting cylinder 501. When the pressure block 504A is engaged, the adjusting rod 502 does not interfere with the latch 504, and the latch 504 is in automatic mode. At this time, the latch 504 is only subjected to the elastic force of the small compression spring 506. When the thick rod 502C is engaged with the pressing block 504A, the adjusting rod 502 applies strong pressure to the latch 504, firmly pressing the latch 504 onto the pipe groove 501B, thereby completely fixing the steel pipe 8 in the pipe groove 501B. When the transition rod 502B comes into contact with the pressing block 504A, as the adjusting disc 508 gradually approaches the mounting cylinder 501, the pressure applied by the transition rod 502B to the pressing block 504A also increases, and the fixing force of the latch 504 on the steel pipe 8 also increases. As the adjusting disc 508 gradually moves away from the mounting cylinder 501, the transition rod 502B also gradually releases the pressing block 504A.

[0042] The thick rod 502C has a slot inside, and a compression spring 508C is fixedly connected to the bottom of the slot. The other end of the compression spring 508C is fixedly connected to a set of pressure rods 508B. The force applied by the adjusting disc 508 is transmitted to the compression spring 508C through the pressure rods 508B and then continues to be applied to the adjusting pressure rod 502. Therefore, the adjusting pressure rod 502 can accept a large compressive force, which is then applied to the latch 504. However, the adjusting pressure rod 502 only requires a small pulling force to release the latch 504. 4. A transition rod 503B is provided in the middle of the adjusting pressure rod 503. A thin rod 503A is fixed to the left end of the transition rod 503B, and a thick rod 503C is fixed to the right side of the transition rod 503B. When the thick rod 503C contacts the extrusion block 505A, the adjusting pressure rod 503 extrudes the pusher 505, the large compression spring 507 is compressed, the front end of the pusher 505 retracts into the pipe groove 501B, and the pusher 505 disengages from the steel pipe 8. At this time, the steel pipe 8 is in the pipe groove. The internal force of 501B is only exerted by the latch 504. When the thin rod 503A engages with the extrusion block 505A, the adjusting pressure rod 503 loses contact with the pusher 505, and the pusher 505 returns to its free state, only subject to the elastic force of the large compression spring 507. At this time, the front end of the pusher 505 continuously extrudes the steel pipe 8. When the latch 504 returns to its free state, the pusher 505 can push the steel pipe 8 out of the fixed pipe groove 501B. When the transition rod 503B contacts the extrusion... When block 505A is pressed, as the adjusting disc 508 gradually approaches the mounting cylinder 501, the pressure exerted by the transition rod 503B on the pressing block 505A increases. As the adjusting disc 508 gradually moves away from the mounting cylinder 501, the transition rod 503B gradually disengages from the pressing block 505A, at which point the pusher 505 returns to its free state. The right end of the thick rod 503C is fixedly connected to the compression spring 508C, and the other end of the compression spring 508C is fixedly connected to another set of pressure rods 508B.

[0043] The length of thin rod 502A is the sum of the lengths of thin rod 503A and transition rod 503B, and the length of thick rod 503C is the sum of the lengths of transition rod 502B and thick rod 502C.

[0044] The four sets of mating relationships between the adjusting disc 508 and the guide rail 103 are as follows:

[0045] 1. When the adjusting disc 508 approaches the mounting cylinder 501 to the closest distance, the first thick rod 502C contacts the first extrusion block 504A, and the latch 504 firmly fixes the steel pipe 8. At the same time, the second thick rod 503C also contacts the second extrusion block 505A, and the pusher 505 opens, losing the pushing force on the steel pipe 8, and the steel pipe 8 is firmly fixed.

[0046] 2. When the adjusting disc 508 approaches the mounting cylinder 501 to the second closest distance, the transition rod 502B engages with the extrusion block 504A, and the latch 504 gradually loosens the steel pipe 8 until finally the small compression spring 506 keeps the steel pipe 8 fixed. At the same time, the thick rod 503C contacts the extrusion block 505A, the pusher 505 remains open, and there is no force between the pusher 505 and the steel pipe 8.

[0047] 3. When the adjusting disc 508 is far away from the mounting cylinder 501 to the second farthest distance, the thin rod 502A cooperates with the extrusion block 504A, the pawl 504 loses the extrusion force on the steel pipe 8, and at the same time the transition rod 503B contacts the extrusion block 505A, the extrusion force of the adjusting rod 503 on the extrusion block 505A becomes smaller and smaller, and the extrusion force of the pusher 505 on the steel pipe 8 gradually increases.

[0048] 4. When the adjusting disc 508 is farthest away from the mounting cylinder 501, the thin rod 502A cooperates with the pressing block 504A, and the pawl 504 loses its pressing force on the steel pipe 8. At the same time, the thin rod 503A cooperates with the pressing block 505A, and the adjusting pressure rod 503 loses its pressing force on the pressing block 505A. Under the elastic force of the large compression spring 507, the pusher 505 pushes the steel pipe 8 out of the fixed pipe groove 501B.

[0049] like Figure 11 and Figure 12As shown, the rotating assembly 4 includes a central rotating shaft 402, which is rotatably connected to the inner wall of the rotating tube 303. The central rotating shaft 402 is also rotatably connected to the through hole 304. The central rotating shaft 402 extends out of the rotating drum 302 through the through hole 304. A second drive motor 401 is fixedly connected to the right side of the housing 1. The output shaft of the second drive motor 401 extends into the housing 1 and is fixedly connected to the central rotating shaft 402. Multiple sets of central gears 403 are fixedly provided on the central rotating shaft 402. The number of central gears 403 is the same as the number of rotating drums 302. Each set of rotating drums 302 has a set of central gears 403 and a fixed frame 404 inside. The fixed frame 404 is provided around the central gears 403. Multiple sets of transmission gears 405 are rotatably connected to the fixed frame 404. The transmission gears 405 mesh with the central gears 403 and also mesh with the fixed gears 501A. Driven by the second drive motor 401, the central shaft 402 drives the central gear 403 to rotate. The central gear 403 transmits power to the transmission gear 405, which in turn drives the mounting cylinder 501 to rotate, thereby causing the steel pipe 8 on the clamping mechanism 5 to rotate. This ensures that the wall of the steel pipe 8 can contact the cutting tool 605B from the outside to the inside, making the cutting operation more uniform and smooth. Each fixed tooth 501A meshes with two transmission gears 405. Because the mounting cylinder 501 has a pipe-fixing groove 501B, the fixed teeth 501A may be discontinuous or incomplete, failing to form a complete ring. By keeping the fixed teeth 501A meshed with the two sets of transmission gears 405, at least one set of transmission gears 405 is engaged with the fixed teeth 501A at all times, transmitting the power of the second drive motor 401 to the clamping mechanism 5 in real time, allowing the clamping mechanism 5 to maintain its rotation.

[0050] like Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, the cutting mechanism 6 includes a mounting frame 601. A sliding hole 601A is provided at the center of the mounting frame 601, which is slidably connected to the outer wall of the rotating tube 303. A limiting groove 601B is fixedly provided on the side wall of the sliding hole 601A, and the limiting groove 601B cooperates with the straight rail 303A. Therefore, the mounting frame 601 can be moved on the rotating tube 303 to adjust the cutting position of the steel pipe 8. Multiple sets of support frames 601C are fixedly connected to the mounting frame 601. Each support frame 601C is rotatably connected to a connecting frame 603. An electric push rod 602 is rotatably connected to the rear of the connecting frame 603, and the other end of the electric push rod 602 is rotatably connected to the mounting frame 601. A mounting bracket is fixedly connected to the front of the connecting frame 603. A vertical mounting plate 604 is provided, on which a slide rail 604A is provided. A lifting assembly 606 and a cutting assembly 605 are provided on the vertical mounting plate 604. The cutting assembly 605 includes a second motor 605A and a cutting blade 605B. The lifting assembly 606 includes a first motor 606A, which is fixedly connected to the top of the vertical mounting plate 604. The output shaft of the first motor 606A is fixedly connected to a screw 606B. The screw 606B is fixedly connected to the vertical mounting plate 604 through a fixed slide block. A lifting block 606C is threadedly connected to the screw 606B. A slide rod 606D is slidably connected to the other side of the lifting block 606C. The slide rod 606D is fixedly connected to the vertical mounting plate 604 through a fixed slide block.

[0051] Driven by motor 606A, screw 606B rotates, causing lifting block 606C to move up and down, thereby driving cutting assembly 605 to gradually cut from the pipe wall towards the center of steel pipe 8. The outer wall of lifting block 606C is fixedly connected to motor 605A. The output shaft of motor 605A passes through lifting block 606C and is fixedly connected to cutting tool 605B. Motor 605A drives cutting tool 605B to rotate, performing the pipe cutting operation. Multiple sets of distance sensors 607 are fixedly connected to the bottom of mounting plate 604. The distance sensors 607 detect the distance between the bottom of mounting plate 604 and the side wall of steel pipe 8 in real time, and the distance between the mounting plate 604 and the side wall of steel pipe 8 is controlled by the extension and retraction of electric push rod 602, ensuring that the distance between them remains constant. This allows for the gradual cutting of various types of steel pipe 8, such as square and irregularly shaped pipes, from the outer wall to the center, ensuring cutting quality.

[0052] Working principle:

[0053] 1. Place the steel pipe 8 to be processed into the storage bin 101, start the electric push rod 201 to push the steel pipe 8 into the solid pipe groove 501B, the steel pipe 8 squeezes open the buckle 504 and enters the innermost part of the solid pipe groove 501B.

[0054] 2. Under the guidance of the guide rail 103, the adjusting plate 508 gradually approaches the mounting cylinder 501, and the latch 504 firmly latches the steel pipe 8 to achieve fixation. The rotating component 4 drives the mounting cylinder 501 to rotate, causing the steel pipe 8 to rotate.

[0055] 3. When the electric push rod 602 is started, the mounting plate 604 maintains a constant distance from the wall of the steel pipe 8. The motor 605A starts and drives the cutting tool 605B to rotate. The motor 606A starts and drives the lifting block 606C to gradually descend, cutting the steel pipe 8. Since the steel pipe 8 is rotating, the cutting tool 605B cuts from the outer wall of the steel pipe 8 towards the center, resulting in a better cutting effect.

[0056] 4. During the cutting process, the drive motor 301 continuously drives the rotating drum 302 to rotate, and the steel pipe 8 moves forward continuously. When the steel pipe 8 moves close to the bottom of the housing 1, the adjusting plate 508 gradually moves away from the mounting cylinder 501 to the second farthest distance under the guidance of the guide slide rail 103. At this time, the clamping claw 504 gradually releases the steel pipe 8, and the push claw 505 pops the steel pipe 8 out of the innermost side of the fixed pipe groove 501B. With the assistance of the tube retraction claw 7, the steel pipe 8 completely disengages from the clamping mechanism 5 and falls from the tube retraction port 102, leaving the housing 1.

[0057] 5. The rotating drum 302 continues to rotate, and the adjusting plate 508 moves further away from the mounting cylinder 501. At this time, the pusher 505 opens and moves away from the range of the fixed pipe groove 501B. The latch 504 only relies on the small compression spring 506 to maintain its most basic function, so that the new steel pipe 8 to be processed can be pushed into the fixed pipe groove 501B and the cutting operation can start again.

[0058] This invention, by setting up a storage chamber 101 and a pusher assembly 2, enables the steel pipe 8 to enter from the radial direction of the rotating cylinder 3. Compared with the traditional axial direction entry, its entry and exit speed from the shell 1 is faster, greatly improving production efficiency. By setting up a clamping mechanism 5, the steel pipe 8 can be fixed at the same time, and it can also rotate, driving the fixed steel pipe 8 to rotate simultaneously. This ensures that the pipe wall of the steel pipe 8 can be cut, and the cutting operation gradually rotates from the outer wall of the steel pipe 8 to cut into the center of the steel pipe 8, ensuring the cutting quality of the cutting surface.
