Description

Technical Field

[0001] This application relates to the field of cutting devices, and more particularly to a pipe fitting follow-up cutting device. Background Technology

[0002] On a continuous pipe fitting production line, frequent cutting of moving pipes is a key processing step, which reduces the number of downtime cutting steps and improves the overall production efficiency of the pipe production line.

[0003] Current pipe fitting follow-up cutting devices mainly consist of a support, a cutting frame, and a feeding frame. The cutting frame is slidably connected to the support, and the feeding frame is positioned opposite to the support. The cutting frame contains the cutting structure and moves with the pipe fitting. It cuts the pipe fitting when the cutting frame and the pipe fitting are relatively stationary, achieving the follow-up cutting function. The feeding frame contains V-grooves. After cutting, the pipe fitting moves into the V-grooves, which contain multiple feeding plates with parallel rotating shafts between adjacent plates, allowing finished and defective products to be transported to different stacking racks for collection. To improve the stability of the cutting structure when cutting pipe fittings, a spray pipe is usually installed on the cutting frame, connected to cutting fluid, to cool the cutting structure and the pipe fitting.

[0004] Because cutting fluid is inherently irritating, and the cut pipes are typically transported directly to the unloading rack for stacking, some cutting fluid remains on the surface of the pipes at this point. This can easily affect workers and the pipe production environment, and therefore needs to be improved. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a pipe fitting follow-up cutting device.

[0006] This application provides a pipe fitting follow-up cutting device, which adopts the following technical solution: A pipe fitting follow-up cutting device includes a first support and a second support arranged opposite to each other. A cutting frame is slidably connected to the first support, and a cutting component is provided on the cutting frame. A feeding component is provided on the second support. Two sets of cleaning components for cleaning the surface of the pipe fitting are arranged opposite to each other between the first support and the second support.

[0007] By adopting the above technical solution, when pipe fittings need to be cut to a fixed length, the cutting frame controls the movement of the cutting assembly, ensuring that the cutting assembly and the pipe fitting move at the same speed, making them relatively stationary. At this point, the cutting assembly can cut the pipe fitting. The cut pipe fitting is then conveyed to the second support, while the cleaning assembly cleans the surface of the pipe fitting, making it less likely for cutting fluid to adhere to the surface, thus reducing the possibility of cutting fluid affecting worker safety and the production environment.

[0008] Preferably, the cleaning assembly includes a cleaning frame, a support plate, a driving component, and a plurality of cleaning components. The cleaning frame is disposed between a first support and a second support. The support plate is rotatably connected to the cleaning frame. The driving component is connected to the support plate. The plurality of cleaning components are evenly disposed on the support plate. The cleaning component includes a cleaning seat, a movable column, a support plate, and a cleaning block. The cleaning seat is mounted on a support plate and has a through hole. The movable column is slidably connected in the through hole, and a reset component for controlling the movable column to reset is provided in the through hole. The support plate is mounted on the movable column, and the cleaning block is located on the side of the support plate away from the movable column. The cleaning frame is equipped with several cylinders, each corresponding to a cleaning seat. Each cylinder has a push rod at its output end, and each push rod corresponds to a movable column.

[0009] By adopting the above technical solution, during the pipe conveying process, the cylinder controls the movement of the push rod at the corresponding position, which in turn drives the movement of the moving column at the corresponding position. The moving column then drives the support plate and the cleaning block to move, so that the cleaning block comes into contact with the pipe. At this time, the cleaning block can clean the cutting fluid on the surface of the pipe. When the cleaning block needs to be replaced, the cylinder resets and drives the push rod to reset. Under the action of the reset component, the moving column, support plate, and cleaning block automatically reset. The drive component then controls the rotation of the support plate, and the support plate adjusts the position of the cleaning seat so that the new cleaning block is opposite the pipe. This achieves the function of automatically cleaning the pipe and provides convenience for replacing the cleaning block.

[0010] Preferably, the reset component includes a movable plate and a spring, the inner wall of the through hole is provided with a movable groove, the movable plate is slidably connected in the movable groove, the movable plate is connected to the movable column, one end of the spring is connected to the inner wall of the movable groove, and the other end is connected to the movable plate.

[0011] By adopting the above technical solution, the moving column moves, causing the moving plate to move as well, and the moving plate compresses the spring. After the push rod releases the thrust on the moving column, the moving plate automatically resets under the action of the spring's rebound force, allowing the cleaning block to separate from the pipe fitting for replacement.

[0012] Preferably, the driving component includes a first motor, a first transmission wheel, and a second transmission wheel. The first motor is mounted on the cleaning frame, the first transmission wheel is mounted on the output end of the first motor, and the second transmission wheel is mounted on the support plate. A transmission belt is wound around the second transmission wheel and the first transmission wheel.

[0013] By adopting the above technical solution, the first motor drives the first transmission wheel to rotate, which in turn drives the transmission belt and the second transmission wheel to rotate. The second transmission wheel then drives the support disc to rotate, allowing the support disc to adjust the position of the cleaning seat and achieve the function of automatically replacing the cleaning block.

[0014] Preferably, the cleaning rack is provided with a collection box, the collection box is provided with a support rod, the support rod is provided with a squeezing plate that cooperates with the cleaning block, and the squeezing plate is provided with a plurality of drainage holes.

[0015] By adopting the above technical solution, when the support plate rotates the used cleaning block to face the extrusion plate, the corresponding cylinder is activated and drives the push rod to move, thereby controlling the cleaning block to move towards the extrusion plate. During the contact between the cleaning block and the extrusion plate, the cutting fluid adsorbed in the cleaning block is discharged. At the same time, under the action of the drain hole, the cutting fluid is facilitated to fall into the collection box under its own gravity, making it less likely for the cutting fluid to adhere to the extrusion plate.

[0016] Preferably, the cutting assembly includes a cutting seat, a cutting blade, and a control component for controlling the rotation of the cutting blade. The cutting seat is slidably connected to the cutting frame in a vertical direction, the cutting blade is rotatably connected to the cutting seat, and the control component is disposed on the cutting seat and connected to the cutting blade.

[0017] By adopting the above technical solution, when it is necessary to cut the pipe, the control unit controls the cutting blade to rotate, and the cutting seat then controls the cutting blade to move toward the pipe. When the cutting blade contacts the pipe, it can cut the pipe, thus realizing the function of automatic cutting.

[0018] Preferably, the control component includes a second motor, a first control wheel, and a second control wheel. The second motor is mounted on the cutting seat, the first control wheel is mounted on the output end of the second motor, and the second control wheel is mounted on the rotating shaft of the cutting blade. A control belt is wound around the first and second control wheels.

[0019] By adopting the above technical solution, the second motor drives the first control wheel to rotate, the first control wheel drives the control belt and the second control wheel to rotate in sequence, and the second control wheel can drive the cutting blade to rotate, thus providing convenience for the control of the cutting blade.

[0020] Preferably, a screw is rotatably connected to the cutting frame, the cutting seat is threadedly connected to the screw, and a third motor is provided on the cutting frame, the output end of which is connected to the screw.

[0021] By adopting the above technical solution, when the vertical position of the cutting blade needs to be adjusted, the third motor starts and drives the screw to rotate. Since the cutting seat is slidably connected to the cutting frame, the rotation of the screw can drive the cutting seat to move vertically. The cutting seat then drives the cutting blade to move, so that the cutting blade can cut the pipe fitting, and at the same time, it provides convenience for adjusting the position of the cutting blade.

[0022] Preferably, the cutting frame is equipped with a fourth motor, the output end of the fourth motor is equipped with a gear, and the first bracket is equipped with a rack along its own length direction, the gear meshing with the rack.

[0023] By adopting the above technical solution, when it is necessary to control the movement of the cutting frame, the fourth motor starts and drives the gear to rotate. At this time, under the cooperation of the gear and rack, the cutting frame can move along the length direction of the first support, thus facilitating the adjustment of the position of the cutting frame, and at the same time making it easy to drive the cutting frame to maintain relative stillness with the pipe.

[0024] Preferably, the feeding assembly includes a main shaft and several feeding seats. The main shaft is rotatably connected to a second support. Each feeding seat is disposed on the main shaft. The second support is provided with a guide frame. The guide frame has a support slope for supporting the pipe and a guide slope for guiding the pipe. The support slope and the guide slope have opposite inclination directions. The guide frame has several feeding holes. Each feeding seat corresponds to one feeding hole. Each feeding seat is provided with several feeding plates.

[0025] By adopting the above technical solution, after the pipe fitting moves to the guide frame on the second support, the supporting inclined surface provides support for the pipe fitting. After the pipe fitting is cut to a fixed length, the spindle rotates and drives the unloading seat to rotate, which in turn drives the unloading plate to rotate. The unloading plate contacts the pipe fitting and separates the pipe fitting from the supporting inclined surface. The unloading plate continues to rotate so that the pipe fitting moves to the guide inclined surface, which then guides the pipe fitting, thus realizing the function of automatic unloading.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By setting up a cleaning component, the cutting fluid on the surface of the pipe fittings can be easily cleaned, making it less likely for the cutting fluid to affect workers and the construction environment. By setting up a collection box and a squeezing plate, the collection box facilitates the collection of cutting fluid adsorbed by the cleaning block, and the squeezing plate cooperates with the support plate to squeeze the cleaning block so as to discharge the cutting fluid adsorbed in the cleaning block.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a pipe fitting follow-up cutting device. (Refer to...) Figure 1 A pipe fitting follow-up cutting device includes a first support 1 and a second support 2 arranged opposite to each other. A cutting frame 3 is slidably connected to the first support 1, and a cutting component 31 is arranged on the cutting frame 3. A feeding component 21 is arranged on the second support 2. Two sets of cleaning components 4 are arranged opposite to each other between the first support 1 and the second support 2 for cleaning the surface of the pipe fitting. During the process of the pipe fitting being cut by the cutting component 31 and moving to the second support 2, the cleaning components 4 clean the surface of the pipe fitting, making it less likely for cutting fluid to adhere to the surface of the pipe fitting, thus reducing the possibility of cutting fluid affecting worker safety and the production environment.

[0031] Reference Figure 2The cleaning assembly 4 includes a cleaning frame 41, a support plate 42, a drive component 43, and several cleaning components 44. The cleaning frame 41 is disposed between the first support 1 and the second support 2, and the support plate 42 is rotatably connected to the cleaning frame 41. The drive component 43 is connected to the support plate 42, and the several cleaning components 44 are evenly disposed on the support plate 42.

[0032] The cleaning component 44 includes a cleaning seat 441, a moving column 442, a support plate 443, and a cleaning block 444. The cleaning seat 441 is mounted on the support plate 42 and has a through hole. The moving column 442 is slidably connected in the through hole. A reset component 45 for controlling the resetting of the moving column 442 is provided in the through hole. The support plate 443 is mounted on the moving column 442, and the cleaning block 444 is located on the side of the support plate 443 opposite to the moving column 442. The cleaning frame 41 is equipped with several cylinders 46, each corresponding to a cleaning seat 441. Each cylinder 46 has a push rod 461 at its output end, and each push rod 461 corresponds to a moving column 442. In this embodiment, the cleaning block 444 is a sponge with good adsorption properties to collect the cutting fluid.

[0033] Reference Figure 2 The reset component 45 includes a movable plate 451 and a spring 452. A movable groove is formed on the inner wall of the through hole, and the movable plate 451 is slidably connected in the movable groove. The movable plate 451 is connected to the movable column 442, and one end of the spring 452 is connected to the inner wall of the movable groove, and the other end is connected to the movable plate 451.

[0034] During the pipe conveying process, cylinder 46 controls the movement of push rod 461 at the corresponding position. Push rod 461 then drives the movement of moving column 442 at the corresponding position. Moving column 442 then drives the support plate 443 and cleaning block 444 to move, so that cleaning block 444 comes into contact with the pipe. At this time, spring 452 is in a compressed state, and cleaning block 444 can clean the cutting fluid on the surface of the pipe. When it is necessary to replace cleaning block 444, cylinder 46 resets and drives push rod 461 to reset. Under the action of reset component 45, moving column 442, support plate 443 and cleaning block 444 automatically reset. Drive component 43 then controls support plate 42 to rotate. Support plate 42 adjusts the position of cleaning seat 441 so that new cleaning block 444 is opposite to the pipe. On the one hand, it realizes the function of automatic cleaning of pipe, and on the other hand, it provides convenience for the replacement of cleaning block 444. After the push rod 461 releases the pushing force on the moving column 442, the moving plate 451 automatically resets under the action of the spring 452's rebound force, and the cleaning block 444 can be separated from the pipe fitting so that the cleaning block 444 can be replaced.

[0035] Reference Figure 3The driving component 43 includes a first motor 431, a first transmission wheel 432, and a second transmission wheel 433. The first motor 431 is mounted on the cleaning frame 41, the first transmission wheel 432 is mounted on the output end of the first motor 431, and the second transmission wheel 433 is mounted on the support plate 42. A transmission belt 434 is wound around the second transmission wheel 433 and the first transmission wheel 432. In this embodiment, the first transmission wheel 432 and the second transmission wheel 433 are configured as synchronous pulleys, and the transmission belt 434 is configured as a synchronous toothed belt.

[0036] The first motor 431 drives the first transmission wheel 432 to rotate, which in turn drives the transmission belt 434 and the second transmission wheel 433 to rotate. The second transmission wheel 433 then drives the support plate 42 to rotate, which allows the support plate 42 to adjust the position of the cleaning seat 441 to achieve the function of automatically replacing the cleaning block 444.

[0037] Reference Figure 1 and Figure 4 To facilitate cleaning of the cleaning block 444, a collection box 5 is connected to the cleaning frame 41. The collection box 5 has a support rod, and a squeezing plate 51 that cooperates with the cleaning block 444 is provided on the support rod. Several drainage holes are opened on the squeezing plate 51.

[0038] When the support plate 42 rotates the used cleaning block 444 to face the extrusion plate 51, the corresponding cylinder 46 is activated and drives the push rod 461 to move, thereby controlling the cleaning block 444 to move towards the extrusion plate 51. During the contact between the cleaning block 444 and the extrusion plate 51, the cutting fluid adsorbed in the cleaning block 444 is discharged. At the same time, under the action of the drain hole, the cutting fluid is facilitated to fall into the collection box 5 under its own gravity, making it less likely for the cutting fluid to adhere to the extrusion plate 51.

[0039] Reference Figure 1 The cutting assembly 31 includes a cutting base 311, a cutting blade 312, and a control component for controlling the rotation of the cutting blade 312. The cutting base 311 is slidably connected to the cutting frame 3 in the vertical direction, and the cutting blade 312 is rotatably connected to the cutting base 311. The control component is disposed on the cutting base 311 and is connected to the cutting blade 312.

[0040] The control components include a second motor 313, a first control wheel 314, and a second control wheel 315. The second motor 313 is mounted on the cutting base 311, the first control wheel 314 is mounted on the output end of the second motor 313, and the second control wheel 315 is mounted on the rotating shaft of the cutting blade 312. A control belt 316 is wound around the first control wheel 314 and the second control wheel 315. In this embodiment, the first control wheel 314 and the second control wheel 315 are configured as synchronous pulleys, and the control belt 316 is configured as a synchronous toothed belt. The second motor 313 drives the first control wheel 314 to rotate, which in turn drives the control belt 316 and the second control wheel 315 to rotate. The second control wheel 315 then drives the cutting blade 312 to rotate, thus facilitating the control of the cutting blade 312.

[0041] Reference Figure 5 To facilitate position control of the cutting frame 3 and the cutting seat 311, a screw 32 is rotatably connected to the cutting frame 3, and the cutting seat 311 is threadedly connected to the screw 32. A third motor 33 is provided on the cutting frame 3, and the output end of the third motor 33 is connected to the screw 32.

[0042] The cutting frame 3 is equipped with a fourth motor 34, and the output end of the fourth motor 34 is equipped with a gear 341. The first bracket 1 is equipped with a rack 11 along its own length direction, and the gear 341 meshes with the rack 11.

[0043] When the vertical position of the cutting blade 312 needs to be adjusted, the third motor 33 starts and drives the screw 32 to rotate. Since the cutting seat 311 is slidably connected to the cutting frame 3, the rotation of the screw 32 can drive the cutting seat 311 to move vertically. The cutting seat 311 then drives the cutting blade 312 to move, so that the cutting blade 312 can cut the pipe, and at the same time, it provides convenience for adjusting the position of the cutting blade 312. When the pipe needs to be cut, the fourth motor 34 starts and drives the gear 341 to rotate. At this time, under the cooperation of the gear 341 and the rack 11, the cutting frame 3 can move along the length direction of the first support 1, thus providing convenience for adjusting the position of the cutting frame 3, and at the same time, facilitating the driving of the cutting frame 3 to maintain relative stillness between the pipe and the pipe.

[0044] Reference Figure 1 The feeding assembly 21 includes a main shaft 211 and several feeding seats 212. The main shaft 211 is rotatably connected to the second support 2, and each feeding seat 212 is mounted on the main shaft 211. The second support 2 is provided with a guide frame 6, which has a support inclined surface 61 for supporting the pipe fittings and a guide inclined surface 62 for guiding the pipe fittings. The inclination directions of the support inclined surface 61 and the guide inclined surface 62 are opposite. The guide frame 6 has several feeding holes 63, and each feeding seat 212 corresponds to one feeding hole 63. Each feeding seat 212 is provided with several feeding plates 213.

[0045] After the pipe fitting moves onto the guide frame 6 on the second support 2, the supporting inclined surface 61 provides support for the pipe fitting. After the pipe fitting is cut to a fixed length, the main shaft 211 rotates and drives the unloading seat 212 to rotate, which in turn drives the unloading plate 213 to rotate. The unloading plate 213 contacts the pipe fitting and separates the pipe fitting from the supporting inclined surface 61. The unloading plate 213 continues to rotate so that the pipe fitting moves to the guide inclined surface 62, which then guides the pipe fitting, thus realizing the function of automatic unloading.

[0046] The implementation principle of the pipe fitting follow-up cutting device in this application embodiment is as follows: When a pipe fitting needs to be cut to a fixed length, the cutting frame 3 controls the movement of the cutting component 31 so that the moving speed of the cutting component 31 and the pipe fitting is the same, so that the cutting component 31 and the pipe fitting are relatively stationary. At this time, the cutting component 31 can cut the pipe fitting. The cut pipe fitting is transported to the second support 2, and at the same time, the cleaning component 4 cleans the surface of the pipe fitting, so that the cutting fluid is not easy to adhere to the surface of the pipe fitting, reducing the possibility of the cutting fluid affecting the safety of workers and the production environment.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
