Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a pipe cutting device. Background Technology

[0002] Traditional pipe cutting, especially stainless steel pipe cutting, is mainly done by abrasive wheel saws, but abrasive wheel saws have low cutting accuracy and poor cut quality.

[0003] With the development of industrial technology, laser cutting equipment is being used more and more. It uses a laser beam to irradiate the surface of a workpiece, causing the workpiece to reach its melting or boiling point, and then cuts the pipe to the required length.

[0004] However, in order to achieve automatic feeding, the existing large pipe cutting machines are bulky, and the separate steel pipe clamping device and long track feeding mechanism are difficult to deploy in places with small space, which cannot meet the assembly and use needs of small-area factories. Summary of the Invention

[0005] The purpose of this invention is to provide a pipe cutting device that can automatically feed and cut pipes in situations where the installation space is small, while ensuring positioning accuracy.

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

[0007] A pipe cutting device includes a feeding device, a rolling base, a positioning and fastening device, a laser cutting device, and a controller electrically connected to the feeding device, the rolling base, the positioning and fastening device, and the laser cutting device. The rolling base has a top, a bottom, a feeding end, and a discharging end. The feeding end and the discharging end are disposed opposite to each other between the top and the bottom. The feeding device is fixedly connected to the feeding end of the rolling base, the positioning and fastening device is fixedly connected to the discharging end of the rolling base, and the laser cutting device is fixedly connected to the top of the rolling base and located above the discharging end.

[0008] The controller is used to control the feeding device to pre-clamp the pipe to be cut and drive the pipe to be cut into the rolling base;

[0009] The controller is also used to control the positioning and fastening device to clamp the pipe to be cut after it reaches the target position, and to control the laser cutting device to perform laser cutting on the positioned and clamped pipe. During the laser cutting process, the controller controls the rolling base to drive the pipe to be cut to rotate so as to use the laser cutting device to perform laser cutting on different areas of the pipe.

[0010] Based on this, in this invention, after the feeding device pre-clamps the pipe to be cut under the control of the controller, it drives the pipe to be cut into the rolling base and moves it to below the laser cutting device. After the pipe reaches the target position according to the actual cutting requirements, the controller controls the positioning and fastening device to clamp the pipe. Then, the laser cutting device above the pipe performs laser cutting. Simultaneously, during the laser cutting process, the controller controls the rolling base to drive the positioning and fastening device and the pipe to be cut to rotate, allowing the laser cutting device to perform laser cutting on different areas of the pipe according to the actual cutting requirements, thereby completing the cutting of the pipe. In this invention, the feeding device is fixedly connected to the feeding end of the rolling base, the positioning and fastening device is fixedly connected to the discharge end of the rolling base, and the laser cutting device is fixedly connected to the top of the rolling base, located above the discharge end. Therefore, this invention can centrally set up the feeding device and the positioning and fastening device on the rolling base, which can reduce the footprint of the pipe cutting equipment to a certain extent. Thus, the installation space requirement for the cutting equipment is also relatively reduced. Furthermore, the feeding device controls the feeding of the pipe to be cut, and the positioning and fastening device clamps the positioned pipe. The positioning and fastening device together maintain the height of the pipe, eliminating the need for a separate slide rail and a fixed chuck slidably connected to it to fix the end of the pipe furthest from the laser cutting device. This further reduces the size of the cutting device, thus reducing the required installation space. Additionally, because the feeding and discharging ends are positioned relative to each other at the top and bottom, with the feeding device fixedly connected to the feeding end of the rolling base and the positioning and fastening device fixedly connected to the discharging end, the height of the pipe is consistent at both the feeding and positioning and fastening devices. This ensures the pipe maintains the same height in both devices. After positioning the pipe using the positioning and fastening device, the laser cutting device can maintain a consistent cutting angle relative to the pipe during rotation, thus improving the cutting accuracy of the pipe cutting equipment.

Therefore, they should not be construed as limitations on this invention.

[0080] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0081] Laser cutting technology boasts unique advantages such as high cutting quality, narrow kerf width, high precision, and good surface roughness, making it widely used in profile processing. However, large pipe cutting machines are bulky and require specific installation sites, necessitating separate steel pipe clamping devices and track feeding mechanisms. Deployment is challenging in limited spaces.

[0082] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment of the invention provides a pipe cutting device, including a feeding device 1, a rolling base 4, a positioning and fastening device 2, a laser cutting device 3, and a controller electrically connected to the feeding device 1, the rolling base 4, the positioning and fastening device 2, and the laser cutting device 3. The rolling base 4 has a top, a bottom, a feeding end, and a discharging end; the feeding end and the discharging end are disposed opposite each other between the top and the bottom; the feeding device 1 is fixedly connected to the feeding end of the rolling base 4, the positioning and fastening device 2 is fixedly connected to the discharging end of the rolling base 4, and the laser cutting device 3... The controller is fixedly connected to the top of the rolling base 4 and located above the discharge end; the controller is used to control the feeding device 1 to pre-clamp the tube to be cut and drive the tube to be cut into the rolling base 4; the controller is also used to control the positioning and fastening device 2 to clamp the tube to be cut after the tube to be cut is sent to the target position, and to control the laser cutting device 3 to perform laser cutting on the positioned and clamped tube to be cut, and to control the rolling base 4 to drive the tube to be cut to rotate during the laser cutting process.

[0083] In the specific implementation process, the pipe to be cut is placed in the feeding device 1. The controller controls the feeding device 1 to pre-clamp the pipe to be cut. Then the feeding device 1 works, driving the pipe to be cut from the feeding end of the rolling base 4 to the discharge end. When the pipe to be cut reaches the target position, the controller controls the positioning and fastening device 2 to clamp the pipe to be cut, while ensuring that the height position of the pipe to be cut is consistent at both the feeding device 1 and the positioning and fastening device 2. After that, the controller controls the laser cutting device 3 to perform laser cutting on the pipe to be cut. At the same time, the controller controls the rolling base to make the positioning and fastening device 2 and the pipe to be cut rotate together, cooperating with the laser cutting device 3 to complete the circumferential cutting of the pipe.

[0084] Based on this, in this invention, after the feeding device 1 is pre-clamped by the controller, it is driven to move through the rolling base 4 to below the laser cutting device 3. After the pipe to be cut reaches the target position according to the actual cutting requirements, the controller controls the positioning and fastening device 2 to clamp the pipe to be cut. Then, the laser cutting device 3 above the pipe to be cut performs laser cutting. During the laser cutting process, the controller controls the rolling base 4 to drive the positioning and fastening device 2 and the pipe to be cut to rotate, so that the laser cutting device 3 can perform laser cutting on different areas of the pipe to be cut according to the actual cutting requirements, thereby completing the cutting of the pipe. In this invention, the feeding device 1 is fixedly connected to the feeding end of the rolling base 4, the positioning and fastening device 2 is fixedly connected to the discharge end of the rolling base 4, and the laser cutting device 3 is fixedly connected to the top of the rolling base 4 and located above the discharge end. Based on this, this invention can concentrate the feeding device 1 and the positioning and fastening device 2 on the rolling base 4, which can reduce the cutting speed of the pipe to a certain extent. The floor space required for the cutting equipment is reduced, thus decreasing the need for installation space. Furthermore, the feeding device 1 controls the feeding of the pipe to be cut, and the positioning and fastening device 2 clamps the positioned pipe. The feeding device 1 and the positioning and fastening device 2 work together to maintain the height of the pipe, eliminating the need for a separate slide rail and a fixed chuck slidably connected to the slide rail to fix the end of the pipe away from the laser cutting device 3. This further reduces the size of the cutting equipment, thus further reducing the need for installation space. Additionally, since the feeding end and the discharge end are positioned relative to each other between the top and bottom, with the feeding device fixedly connected to the feeding end of the rolling base 4 and the positioning and fastening device 2 fixedly connected to the discharge end of the rolling base 4, the pipe to be cut can maintain the same height within the feeding device 1 and the positioning and fastening device 2. After positioning the pipe using the positioning and fastening device 2, the laser cutting device 3 can maintain a consistent cutting angle relative to the pipe during its rotation, thus improving the cutting accuracy of the pipe cutting equipment.

[0085] Specifically, such as Figure 3As shown, in the above-mentioned pipe cutting equipment, the feeding device 1 includes a feeding tray 11, a feeding assembly 12 and a lifting assembly 13 electrically connected to the controller; the first side of the feeding tray 11 is fixedly connected to the feeding end of the rolling base 4, and the second side is used to install and fix the feeding assembly 12 and the lifting assembly 13; the lifting assembly 13 is used to adjust the position of the pipe to be cut after entering the feeding device 1 under the control of the controller and to pre-clamp the pipe to be cut; after the feeding assembly 12 pre-clamps the pipe to be cut, it drives the pipe to be cut to move towards the discharge end of the rolling base 4 under the control of the controller. After the pipe to be cut enters the feeding device 1, the controller controls the lifting assembly 13 to adjust the height position of the pipe to be cut and pre-clamp the pipe to be cut at the same time; then, the feeding assembly 12 controls the pipe to be cut to move towards the discharge end of the rolling base 4, thereby realizing the pre-clamping and feeding of the pipe to be cut.

[0086] Specifically, in the aforementioned pipe cutting equipment, the lifting assembly 13 includes a first driving component 131, a first transmission assembly 132, and a driven roller 133. The first driving component 131 is fixedly connected to the second side of the feeding tray 11 and electrically connected to the controller. The first transmission assembly 132 is drivenly connected to the output end of the first driving component 131, and both the driven roller 133 and the feeding assembly 12 are drivenly connected to the first transmission assembly 132. The first transmission assembly 132 is used to move the driven roller 133 and the feeding assembly 12 relatively closer or further apart under the drive of the first driving component 131, thereby pre-clamping or releasing the pipe to be cut. The controller controls the operation of the first driving component 131, transmitting power to the driven roller 133 and the feeding assembly 12 through the first transmission assembly 132, causing the driven roller 133 and the feeding assembly 12 to move relatively closer or further apart, thereby achieving position adjustment and pre-clamping of the pipe to be cut.

[0087] Specifically, in the aforementioned pipe cutting equipment, the first transmission assembly 132 includes a first driving bevel gear 1321, a first driven bevel gear 1322, and a first lifting screw 1323; the first lifting screw 1323 includes a first fixing member and a first threaded rod, the first fixing member is fixedly connected to the second side of the feed tray 11, and the first threaded rod is rotatably connected to the first fixing member and its axis is limited, so that the first threaded rod can only rotate and cannot move along the axial direction; the first driving bevel gear 1321 is drivenly connected to the output end of the first driving member 131, and the first driven bevel gear 1322 is fixedly connected to the first end of the first threaded rod; the first driving bevel gear 1321 and the first driven bevel gear 1322... The transmission connection includes a first threaded rod comprising a first section near the first driven bevel gear 1322 and a second section away from the first driven bevel gear 1322, with the threads of the first and second sections rotating in opposite directions. The first end of the driven roller 133 is threadedly connected to the first section of the first threaded rod, and the first end of the feeding assembly 12 is threadedly connected to the second section of the first threaded rod. A controller controls the first drive member 131 to rotate the first drive bevel gear 1321, which in turn causes the first threaded rod to rotate via the first driven bevel gear 1322. This, in turn, causes the driven roller 133 and the feeding assembly 12 to move in the direction of the first threaded rod, bringing them closer together or further apart. With this configuration, when the first drive member 131 rotates the first threaded rod, the feeding assembly 12 and the driven roller 133 move in opposite directions, achieving pre-clamping or loosening of the tube to be cut.

[0088] Specifically, in the aforementioned pipe cutting equipment, the lifting assembly 13 further includes a second lifting screw 1324 fixedly connected to the second side of the feed tray 11. The second lifting screw 1324 is arranged parallel to the first lifting screw 1323. The second lifting screw 1324 includes a second fixing member and a second threaded rod. The second fixing member is fixedly connected to the second side of the feed tray 11, and the second threaded rod is rotatably connected to the second fixing member and its axis is limited, so that the second threaded rod can only rotate and cannot move along the axial direction. The second threaded rod includes a first section near the first driving member 131 and a second section away from the first driving member 131, and the threads of the first section and the second section of the second threaded rod have opposite directions. The second end of the driven roller 133 is connected to the second threaded rod. The first threaded connection connects the second end of the feeding assembly 12 to the second threaded section of the second threaded rod. When the driven roller 133 and the feeding assembly 12 are relatively close or relatively far apart under the action of the first lifting screw 1323, they drive the second threaded rod, which is threadedly connected to the driven roller 133 and the feeding assembly 12 respectively, to rotate. At this time, the driven roller 133 and the feeding assembly 12 move in opposite directions relative to the second threaded rod. Since the second threaded rod is rotatably connected to the second fixed part and its axis is limited, and the first threaded rod is rotatably connected to the first fixed part and its axis is limited, the positions of the first threaded rod and the second threaded rod relative to the feeding tray 11 do not change. Therefore, the included angle between the driven roller 133 and the feeding assembly 12 and the first lifting screw 1323 remains unchanged. The first and second sections of the second threaded rod have opposite thread directions, and the driven roller 133 is threadedly connected to the first section of the second threaded rod. The feeding assembly 12 is threadedly connected to the second section of the second threaded rod. When the first threaded rod rotates, it drives the feeding assembly 12 and the driven roller 133 to move in opposite directions. The feeding assembly 12 and the driven roller 133 drive the second threaded rod of the second lifting screw 1324 to rotate. When the feeding assembly 12 and the driven roller 133 stop moving, the feeding assembly 12 and the driven roller 133 also remain stationary relative to the second threaded rod. This ensures that the angle between the driven roller 133 and the feeding assembly 12 and the first lifting screw 1323 remains constant, thereby enhancing the strength of the device and the accuracy of the height of the pipe to be cut.

[0089] Specifically, in the aforementioned pipe cutting equipment, the feeding assembly 12 includes a second driving component 121, a second transmission assembly 122, and a driving roller 123. The second driving component 121 is fixedly connected to the second side of the feeding tray 11 and electrically connected to the controller. The second transmission assembly 122 is drivenly connected to the output end of the second driving component 121, and the driving roller 123 is drivenly connected to the second transmission assembly 122. The second transmission assembly 122 is used to drive the driving roller 123 to rotate under the drive of the second driving component 121, thereby causing the pipe to be cut to move towards the discharge end of the rolling base 4. The controller controls the operation of the second driving component 121, which drives the driving roller 123 to rotate through the second transmission assembly 122. Under the rolling action, the pipe to be cut moves towards the discharge end of the rolling base 4, realizing the feeding of the pipe to be cut.

[0090] Specifically, in the aforementioned pipe cutting equipment, the second transmission assembly 122 includes a first spur gear 1221 and a second spur gear 1222. The first spur gear 1221 is drivenly connected to the output end of the second drive member 121, and the second spur gear 1222 is fixedly connected to the drive roller 123. The first spur gear 1221 and the second spur gear 1222 are also connected in a transmission manner. With this configuration, the controller controls the second drive member 121 to drive the first spur gear 1221 to rotate, which in turn drives the second spur gear 1222 to rotate, causing the drive roller 123 to rotate. This, in turn, drives the pipe to be cut towards the discharge end of the rolling base 4. The spur gears have high transmission efficiency, improving the working efficiency of the feeding assembly 12.

[0091] Specifically, in the aforementioned pipe cutting equipment, the feeding device 1 further includes a feeding sensor and a sensor bracket 14; the sensor bracket 14 is disposed on the second side of the feeding tray 11, and the feeding sensor is disposed on the sensor bracket 14 and electrically connected to the controller; exemplarily, the feeding sensor is an XKC-001A-T active infrared beam sensor. The feeding sensor can detect the position information of the pipe to be cut relative to the rolling base 4 and send the position information to the controller. It should be understood that the feeding sensor can also be directly disposed on the second side of the feeding tray 11 without the need for a sensor bracket.

[0092] Specifically, such as Figure 4As shown, in the aforementioned pipe cutting equipment, the positioning and fastening device 2 includes a positioning tray 21, and a first fastening component 22 and a second fastening component 23 electrically connected to the controller. The positioning tray 21 is fixedly connected to the discharge end of the rolling base 4, the first fastening component 22 is fixedly connected to the first side of the positioning tray 21, and the second fastening components 23 are both fixedly connected to the second side of the positioning tray 21, respectively used to restrict the movement of the pipe to be cut in the first direction and the second direction. The first direction and the second direction have a preset angle, preferably 90°. By controlling the first fastening component 22 and the second fastening component 23 respectively, the movement of the pipe to be cut in the first direction and the second direction is restricted, preventing the pipe to be cut from sliding relative to the positioning and fastening device 2, and ensuring the working stability of the device during the cutting process.

[0093] Specifically, in the aforementioned pipe cutting equipment, both the first fastening assembly 22 and the second fastening assembly 23 include a third driving component 221, a third transmission assembly 222, a first idler roller 223, and a second idler roller 224. The third driving component 221 is fixedly connected to the positioning tray 21 and electrically connected to the controller. The third transmission assembly 222 is drivenly connected to the output end of the third driving component 221, and the first idler roller 223 and the second idler roller 224 are drivenly connected to opposite ends of the third transmission assembly 222. The third transmission assembly 222 is used to move the first idler roller 223 and the second idler roller 224 closer or further apart under the drive of the third driving component 221. The controller controls the operation of the third driving component 221, transmitting power to the first idler roller 223 and the second idler roller 224 through the third transmission assembly 222, causing the first idler roller 223 and the second idler roller 224 to move closer or further apart, thereby clamping or releasing the pipe to be cut.

[0094] Specifically, in the aforementioned pipe cutting equipment, the third transmission assembly 222 includes a second driving bevel gear 2221, a second driven bevel gear 2222, and a first fastening screw 2223; the first fastening screw 2223 includes a third fixing member and a third threaded rod, the third fixing member is fixedly connected to the positioning tray 21, and the third threaded rod is rotatably connected to the third fixing member and its axis is limited; the second driving bevel gear 2221 is drivenly connected to the output end of the third transmission assembly 222, the second driven bevel gear 2222 is fixedly connected to the first end of the third threaded rod, and the second driving bevel gear 2221 and the second driven bevel gear 2222 are connected in a transmission manner; the third threaded rod The third threaded rod includes a first section near the second driven bevel gear 2222 and a second section away from the second driven bevel gear 2222; the first and second sections of the third threaded rod have opposite thread directions; the first idler roller 223 is threadedly connected to the first section of the third threaded rod, and the second idler roller 224 is threadedly connected to the second section of the third threaded rod; the controller is used to control the third drive member 221 to drive the second drive bevel gear 2221 to rotate, and through the second driven bevel gear 2222, to rotate the third threaded rod, thereby causing the first idler roller 223 and the second idler roller 224 to move in the direction of the third threaded rod, so that the first idler roller 223 and the second idler roller 224 are relatively closer or relatively farther apart. The third threaded rod of the first fastening screw 2223 includes a first section near the second driven bevel gear 2222 and a second section away from the second driven bevel gear 2222. The first and second sections of the third threaded rod have opposite thread directions. The first roller 223 is threadedly connected to the first section of the third threaded rod, and the second roller 224 is threadedly connected to the second section of the third threaded rod. Therefore, when the third driving member 221 drives the third threaded rod to rotate, the first roller 223 and the second roller 224 move in opposite directions to achieve clamping or loosening of the tube to be cut.

[0095] Specifically, in the aforementioned pipe cutting equipment, both the first fastening assembly 22 and the second fastening assembly 23 further include a second fastening screw 2224 fixedly connected to the feed tray 11. The second fastening screw 2224 is arranged parallel to the first fastening screw 2223. The second fastening screw 2224 includes a fourth fixing member and a fourth threaded rod. The fourth fixing member is fixedly connected to the positioning tray 21, and the fourth threaded rod is rotatably connected to the fourth fixing member and its axis is limited. The fourth threaded rod includes a first section close to the third driving member 221 and a second section away from the third driving member 221. The threads of the first section and the second section of the fourth threaded rod have opposite directions. The first roller 223 is threadedly connected to the first section of the fourth threaded rod, and the second roller 224 is threadedly connected to the second section of the fourth threaded rod. When the first roller 223 and the second roller 224 are relatively close or relatively far apart under the action of the first fastening screw 2223, they drive the fourth threaded rod to rotate, so that the included angle between the first roller 223 and the second roller 224 and the first fastening screw 2223 remains unchanged. The first and second sections of the fourth threaded rod have opposite thread directions. The first idler roller 223 is threadedly connected to the first section of the fourth threaded rod, and the second idler roller 224 is threadedly connected to the second section of the fourth threaded rod. When the third threaded rod rotates, it drives the first idler roller 223 and the second idler roller 224 to move in opposite directions. The first idler roller 223 and the second idler roller 224 drive the fourth threaded rod of the second fastening screw 2224 to rotate. When the feeding assembly 12 and the driven idler roller 133 stop moving, the feeding assembly 12 and the driven idler roller 133 also remain stationary relative to the fourth threaded rod. This ensures that the angle between the driven idler roller 133 and the feeding assembly 12 and the first fastening screw 2223 remains constant, thereby enhancing the strength of the device and the accuracy of the height of the pipe to be cut.

The vertical slide rail 323 is driven to the output end of the fifth driving component, so as to move along the horizontal slide rail 322 under the drive of the fifth driving component, thereby driving the laser cutting head 31 to move along the horizontal slide rail 322. The controller controls the fourth drive unit 321 to drive the laser cutting head 31 to move on the vertical slide rail 323 to adjust the position of the laser cutting head 31 in the vertical direction. The controller controls the fifth drive unit to drive the vertical slide rail 323 to move on the horizontal slide rail 322 to adjust the position of the laser cutting head 31 in the horizontal direction, thereby realizing the adjustment of the relative position of the laser cutting head 31 with respect to the tube to be cut.

When cutting the pipe to be cut, the controller is also used to control the rotation of the rolling assembly 42, thereby driving the positioning and fastening device 2 to rotate. After the positioning and fastening device 2 clamps the pipe to be cut, the controller controls the rotation of the rolling assembly 42, driving the positioning and fastening device 2 fixedly connected to the rolling assembly 42 to rotate, thereby driving the pipe to be cut, which is clamped by the positioning and fastening device 2, to rotate, so as to cut different areas of the pipe to be cut.

The controller controls the operation of the sixth driving component 421, which drives the rolling component 423 to rotate through the fourth transmission assembly 422, causing the positioning and fastening device 2, which is fixedly connected to the rolling component 423, to rotate, thereby driving the pipe to be cut, which is clamped by the positioning and fastening device 2, to rotate.
