Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe ring cutting devices, in particular to a ring cutting device for processing corrugated pipes. Background Art

[0002] Metal bellows are used to compensate for the mutual displacement of the connection ends of pipelines, machines, and devices, absorb vibration energy, and can play a role in vibration reduction and noise reduction. They have many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance. After the metal bellows are processed and formed, a cutting device is needed to cut the bellows into many small sections.

[0003] When cutting corrugated pipes, the existing circular cutting device usually uses a cutting knife to penetrate the wall of the corrugated pipe, and then rotates the cutting knife to make it surround the corrugated pipe and start cutting. Since the wall of the corrugated pipe is very thin, when one side is subjected to cutting pressure, the pressure is concentrated in one place, which can easily cause the cut of the corrugated pipe to deform, reducing the roundness of the cut and the production yield of the corrugated pipe. In addition, during the cutting process, the debris generated is easy to adhere to the device or the corrugated pipe.

[0013] Furthermore, a ventilation groove is opened in the sleeve on the other side, and an air outlet is opened on one side of the ventilation groove. The support plate has a connecting groove on one side of the ventilation groove, and the air supply pipe is connected with the ventilation groove through the connecting groove.

[0016] The present invention provides a circular cutting device for processing corrugated pipes, which has the following beneficial effects: when in use, the blade can be advanced at a uniform speed, and force can be evenly applied to the corrugated pipe during cutting, thereby preventing the corrugated pipe from being deformed due to uneven force, and during the cutting process, the corrugated pipe can be stably clamped to prevent the corrugated pipe from moving due to force during cutting, thereby causing cutting errors, and when in use, corrugated pipes of different diameters can be transported, clamped and cut, thereby improving the applicability of the device and preventing the corrugated pipe from being deformed when being transported.

[0017] 1. When the present invention is in use, after the cutting point on the bellows reaches the blade, the cutting motor drives the cutting wheel to rotate, so that the gear ring drives the rotating drum to rotate between the sleeves through the ring groove. At the same time, the telescopic rod can drive the slide cylinder to slowly and evenly approach the rotating drum. When the slide cylinder is sleeved on the outer side of the rotating drum, the slide cylinder can apply pressure to the blade, thereby pressing it to slide in the slide cavity and compressing the buffer spring. The slide groove can limit the blade to prevent it from deflecting during movement. The roller and ball in the slide cylinder can make the blade move smoothly in the slide cylinder to prevent the blade from The friction between the blade and the inner wall of the slide affects the rotation of the drum, and as the slide continues to advance, the blade will continue to and slowly approach the bellows until it contacts and cuts it, thereby cutting bellows of different diameters. The symmetrical setting of the blade allows the blade to apply force evenly to the bellows, and the slow transportation and advancement of the blade can prevent the bellows from being deformed due to excessive local force. In summary, when in use, the blade can be advanced at a uniform speed and evenly apply force to the bellows during cutting, thereby preventing the bellows from being deformed due to uneven force.

[0018] 2. In the present invention, after the cutting point on the corrugated tube reaches the blade, the clamping motor is started, so that the clamping wheel drives the double gear ring to rotate on the sleeve, thereby causing the synchronous wheel to drive the sleeve to rotate in the rotating groove, and then the threaded rod drives the clamping plate to move out of the storage groove and approach the corrugated tube until the data detected by the pressure sensor reaches a predetermined value, and the clamping motor stops running, so that the clamping plate clamps the corrugated tube symmetrically to avoid the movement of the corrugated tube under force during cutting, resulting in cutting errors. The engagement of the double gear ring with the sleeve can avoid the deflection of the double gear during rotation, resulting in the inability of the double gear ring to drive all the synchronous wheels to rotate synchronously, and the symmetrically distributed clamping plates make it possible to stably clamp corrugated tubes of different diameters during processing. In summary, during the cutting process, corrugated tubes of different diameters can be stably clamped to avoid the movement of the corrugated tube under force during cutting, resulting in cutting errors.

[0019] 3. Before cutting the bellows, the present invention places the bellows between the air wheels and starts the air pump, which can deliver air into the air supply pipe. The control valve controls the gas flow direction, so that the air flows evenly from the air supply pipe through the shunt pipe into the two air bags, so that the air bags expand and drive the pneumatic plates to move in opposite directions, thereby driving the pressure plate to apply pressure to the air wheel, causing the air wheel to deform until it is tightly attached to the outside of the bellows. The control valve then closes the passage for the air flow to flow into the air bag. The shaft can limit the pneumatic plate and the pressure plate to prevent them from deflecting during movement, and the flexible material of the air wheel can prevent the bellows from being deformed due to excessive force. Starting the drive motor can make the transmission wheel drive the pressure plate to rotate in opposite directions through the shaft, so that the air wheel transports the bellows and temporarily stops after reaching the cutting position. Stop conveying. During the cutting process, the air pump is started, and the air in the exhaust slot can be drawn into the filter frame from the air outlet, and then enter the air pump from the exhaust slot, and is sent from the air supply pipe through the connecting slot into the ventilation slot, and then sprayed out from the nozzle to the bellows, so as to cool the cutting point and the blade, and blow away the debris generated during cutting from the bellows and the blade to avoid debris adhesion, and the blown-off debris will fall into the exhaust slot with the flow of air flow, and be carried to the filter frame by the air flow. The filter frame filters the air flow and retains the debris in the filter frame to avoid debris entering the air pump and causing damage to the air pump. When the filter frame is full, the filter frame can be taken out of the placement slot for cleaning. In summary, when in use, corrugated pipes of different diameters can be flexibly conveyed, and the debris generated during cutting can be cleaned and collected. BRIEF DESCRIPTION OF THE DRAWINGS

A slide cylinder 306 is provided on one side of the rotating cylinder 301, and a roller 307 and a ball 308 are engaged and rotatably connected inside the slide cylinder 306.

[0029] See also Figures 1 to 6The blade 305 is slidably connected with the rotating cylinder 301 through the sliding cavity 302, and the blade 305 is elastically connected with the rotating cylinder 301 through the buffer spring 304, the sliding cylinder 306 is slidably connected with the rotating cylinder 301, the telescopic rod 309 is fixed on the support plate 2, the toothed ring 310 is meshed with the cutting wheel 311, the middle part of the support plate 2 is connected with the sleeve 4, and the side of the sleeve 4 close to each other is provided with an annular groove 5, the rotating cylinder 301 is rotatably connected with the sleeve 4 through the annular groove 5, and the toothed ring 310 is rotatably connected with the rotating cylinder 301 through the annular groove 5, and the sleeve 4 is symmetrically provided with a receiving groove 6, and one side of the receiving groove 6 is provided with a There is a rotating groove 7, a clamping plate 8 is slidably connected in the receiving groove 6, and a threaded rod 9 is connected to one side of the clamping plate 8, a pressure sensor is arranged in the clamping plate 8, a sleeve 10 is rotatably connected in the rotating groove 7, and a synchronous wheel 11 is connected to one side of the sleeve 10, a double gear ring 12 is arranged on one side of the synchronous wheel 11, and a clamping wheel 13 is arranged on one side of the double gear ring 12, and a clamping motor 14 is connected to one side of the clamping wheel 13, the sleeve 10 is threadedly connected to the threaded rod 9, the synchronous wheel 11 is meshed with the double gear ring 12, and the double gear ring 12 is rotatably connected to the sleeve 4, and the double gear ring 12 is meshed with the clamping wheel 13;

[0030] The specific operation is as follows. When in use, after the cutting point on the bellows reaches the blade 305, the cutting motor 312 drives the cutting wheel 311 to rotate, so that the gear ring 310 can drive the rotating cylinder 301 to rotate between the sleeve 4 through the annular groove 5. At the same time, the telescopic rod 309 can drive the slide 306 to slowly and evenly approach the rotating cylinder 301. When the slide 306 is sleeved on the outside of the rotating cylinder 301, the slide 306 can apply pressure to the blade 305, thereby pressing it to slide in the sliding cavity 302 and compressing the buffer spring 304. The slide groove 303 can limit the blade 305 to prevent it from When deflection occurs during the movement, the roller 307 and the ball 308 in the slide 306 can make the blade 305 move smoothly in the slide 306, so as to prevent the friction between the blade 305 and the inner wall of the slide 306 from affecting the rotation of the drum 301. As the slide 306 continues to advance, the blade 305 will continue to and slowly approach the bellows until it contacts and cuts it, thereby cutting bellows of different diameters. The symmetrical setting of the blade 305 allows the blade 305 to apply a balanced force to the bellows, and the slow transportation and advancement of the blade 305 can avoid local damage to the bellows. The bellows is deformed due to excessive force. In summary, when in use, the blade 305 can be pushed forward at a uniform speed, and the bellows can be evenly forcefully applied during cutting, thereby preventing the bellows from being deformed due to uneven force. After the cutting point on the bellows reaches the blade 305, the clamping motor 14 is started, so that the clamping wheel 13 drives the double gear ring 12 to rotate on the sleeve 4, thereby causing the synchronous wheel 11 to drive the sleeve 10 to rotate in the rotating groove 7, and then the threaded rod 9 drives the clamping plate 8 to move out of the storage groove 6 and approach the bellows, until the data detected by the pressure sensor reaches a predetermined value, and the clamping motor 14 stops. During operation, the clamping plates 8 can symmetrically clamp the corrugated tube to avoid the movement of the corrugated tube under force when cutting, which may lead to cutting errors. The engagement of the double gear ring 12 with the sleeve 4 can avoid the deviation of the double gear during rotation, which may cause the double gear ring 12 to be unable to synchronously drive all the synchronous wheels 11 to rotate, and the symmetrically distributed clamping plates 8 can stably clamp corrugated tubes of different diameters during processing. In summary, during the cutting process, corrugated tubes of different diameters can be stably clamped to avoid the movement of the corrugated tube under force during cutting, which may lead to cutting errors.

The support plate 2 is symmetrically provided with placement grooves 17 on both sides of the suction groove 15, and a filter frame 18 is slidably connected in the placement groove 17. A suction groove 19 is provided on one side of the placement groove 17, and an air pump 20 is connected to one side of the suction groove 19. An air supply pipe 21 is connected to one side of the air pump 20. A control valve is provided at the bifurcation of the air supply pipe 21.

A ventilation groove 22 is provided in the sleeve 4 on the other side, and an air outlet 23 is provided on one side of the ventilation groove 22. The support plate 2 is provided with a connecting groove 24 on one side of the ventilation groove 22, and the air supply pipe 21 passes through the connecting groove 24. It is connected to the ventilation groove 22, and the air outlets 23 are equidistantly distributed around the ventilation groove 22. A column 25 is symmetrically arranged on one side of the chassis 1, and a shaft 26 is symmetrically connected to the middle of the column 25 for rotation. Transmission wheels 27 are symmetrically connected to both sides of the shaft 26, and a driving motor 28 is connected to one side of the transmission wheel 27. A pressure plate 29 is slidably connected to the outer side of the shaft 26, and an air wheel 30 is arranged between the pressure plates 29. The air wheel 30 is made of a flexible elastic material. An air bag 31 is connected to one side of the column 25, and a pneumatic plate 32 is connected to the side of the air bag 31 away from the column 25. A shunt pipe 33 is connected to one side of the air bag 31, and the shunt pipe 33 is connected to the air supply pipe 21, and the pneumatic plate 32 is slidably connected to the shaft 26;

[0032] The specific operation is as follows. Before cutting the bellows, place the bellows between the air wheels 30 and start the air pump 20. The air pump 20 can deliver air into the air supply pipe 21. The control valve controls the gas flow direction, so that the air flows evenly from the air supply pipe 21 through the diverter pipe 33 into the two air bags 31, so that the air bags 31 expand and drive the pneumatic plates 32 to move in opposite directions, thereby driving the pressure plate 29 to apply pressure to the air wheel 30, so that the air wheel 30 is deformed to be close to the outside of the bellows, and then the control valve closes the passage for the air flow to flow into the air bag 31. The shaft 26 can limit the pneumatic plate 32 and the pressure plate 29 to prevent them from deflecting during movement, and the flexible material of the air wheel 30 can prevent the bellows from being deformed due to excessive force. Starting the drive motor 28 can make the transmission wheel 27 drive the pressure plate 29 to rotate in opposite directions through the shaft 26, so that the air wheel 30 transports the bellows to the cutting site. The conveying is then suspended. During the cutting process, the air pump 20 is started, and the air in the exhaust slot 15 can be drawn into the filter frame 18 from the air outlet 16, and then enters the air pump 20 from the exhaust slot 19, and is sent from the air supply pipe 21 to the ventilation slot 22 through the connecting slot 24, and then is sprayed out from the nozzle to the bellows, so as to cool the cutting part and the blade 305, and blow off the debris generated during cutting from the bellows and the blade 305 to prevent the debris from adhering, and the blown debris will fall into the exhaust slot 15 with the flow of air flow, and be carried by the air flow to the filter frame 18, the filter frame 18 filters the air flow, and intercepts the debris in the filter frame 18, so as to prevent the debris from entering the air pump 20 and causing damage to the air pump 20, and when the filter frame 18 is full, the filter frame 18 can be taken out from the placement slot 17 for cleaning. In summary, when in use, bellows of different diameters can be flexibly conveyed, and the debris generated during cutting can be cleaned and collected.

[0033] In summary, when using the ring cutting device for processing bellows, first place the bellows between the air wheels 30, start the air pump 20, and the air pump 20 can deliver air into the air supply pipe 21. The control valve controls the gas flow direction, so that the air flows evenly from the air supply pipe 21 through the diverter pipe 33 into the two air bags 31, so that the air bags 31 expand and drive the pneumatic plates 32 to move in opposite directions, thereby driving the pressure plate 29 to apply pressure to the air wheel 30, so that the air wheel 30 is deformed to be close to the outside of the bellows, and then the control valve closes the passage for the air flow to flow into the air bag 31. The shaft 26 can limit the pneumatic plate 32 and the pressure plate 29 to prevent them from deflecting when moving, and the flexible material of the air wheel 30 can prevent the bellows from being deformed due to excessive force, and the drive motor is started. 28, the transmission wheel 27 can drive the pressure plate 29 to rotate in the opposite direction through the shaft 26, so that the air wheel 30 can transport the bellows. After the cutting point on the bellows reaches the blade 305, the transportation is suspended, and the clamping motor 14 is started, so that the clamping wheel 13 drives the double gear ring 12 to rotate on the sleeve 4, so that the synchronous wheel 11 drives the sleeve 10 to rotate in the rotating groove 7, and then the threaded rod 9 drives the clamping plate 8 to move out of the storage groove 6 and approach the bellows until the data detected by the pressure sensor reaches a predetermined value. The clamping motor 14 stops running, so that the clamping plate 8 symmetrically clamps the bellows to avoid the bellows moving after being subjected to force when cutting the bellows, resulting in cutting errors. The engagement of the double gear ring 12 with the sleeve 4 can avoid the double gear ring 12 from moving due to the force applied to the bellows. When the wheel is rotated, it deviates, resulting in the double gear ring 12 being unable to synchronously drive all the synchronous wheels 11 to rotate, and the symmetrically distributed clamping plates 8 make it possible to stably clamp the corrugated pipes of different diameters during processing. After the clamping is stable, the cutting motor 312 drives the cutting wheel 311 to rotate, so that the gear ring 310 can drive the rotating cylinder 301 to rotate between the sleeves 4 through the annular groove 5. At the same time, the telescopic rod 309 can drive the slide 306 to slowly and evenly approach the rotating cylinder 301. When the slide 306 is sleeved on the outside of the rotating cylinder 301, the slide 306 can apply pressure to the blade 305, thereby pressing it to slide in the sliding cavity 302 and compressing the buffer spring 304. The slide groove 303 can limit the blade 305 to prevent it from deviating during the movement. The roller 307 and the ball bearing 308 in the slide cylinder 306 can make the blade 305 move smoothly in the slide cylinder 306, so as to prevent the friction between the blade 305 and the inner wall of the slide cylinder 306 from affecting the rotation of the rotating drum 301. As the slide cylinder 306 continues to advance, the blade 305 will continue to and slowly approach the bellows until it contacts and cuts it, thereby cutting bellows of different diameters. The symmetrical arrangement of the blade 305 allows the blade 305 to apply a balanced force to the bellows, and the slow transportation and advancement of the blade 305 can prevent the bellows from being deformed due to excessive local force. During the cutting process, the air pump 20 is started, and the air in the exhaust slot 15 can be drawn into the filter frame 18 from the air outlet 16, and then enters the air pump 20 from the exhaust slot 19.It is sent into the ventilation groove 22 through the communication groove 24 from the air supply pipe 21, and then sprayed out from the nozzle onto the corrugated pipe to cool the cutting area and the blade 305, and blow off the debris generated during cutting from the corrugated pipe and the blade 305 to avoid debris adhesion. The blown-off debris will fall into the air extraction groove 15 along with the airflow and be carried by the airflow into the filter frame 18. The filter frame 18 filters the airflow and intercepts the debris in the filter frame 18 to avoid the debris entering the air pump 20 and causing damage to the air pump 20. When the filter frame 18 is full, the filter frame 18 can be taken out from the placement groove 17 for cleaning.
