Description
Technical Field
[0001] The invention relates to the technical field of pipe processing, and in particular to a dust collecting device for mechanical processing. Background Art
[0002] The traditional pipe cutting machine has a cutting range of 75-1000mm and a wall thickness of 3mm. The pipe cutting machine is light, easy to carry and easy to operate on site. It can be used to cut steel, plastic, copper, cast iron, stainless steel and multi-layer pipes. It is mostly used in house construction, shipyards, automobile production, industrial pipeline equipment, pulp, papermaking, chemicals, boilers, water pumping stations, etc., construction site fresh water and wastewater systems, municipal heating and cooling systems, urban natural gas pipelines, municipal engineering such as hospitals, office buildings, buildings and large public buildings, maintenance and repair work for medium and large industries, power stations, installation companies, front assemblies in workshops, automatic sprinkler systems, etc., pipeline repair processing.
[0003] However, in the prior art, traditional pipe cutting machines, when in use, mostly adopt a processing form in which the blade rotates and the pipe is fixed. Although this method can cut the pipe, when cutting large-diameter pipes, a large-volume blade needs to be replaced, and the application range of the equipment is relatively small. Although the rotation of the pipe can assist in cutting during the cutting process, the pipe is prone to jumping and falling off, affecting the cut surface and cutting accuracy. In addition, during high-speed cutting, dust and debris generated by cutting will splash everywhere. Long-term high-speed cutting and high temperature will cause great damage to the blade. The metal blade will undergo certain deformation due to thermal expansion and contraction and the reaction force of external cutting, which will affect subsequent cutting. Summary of the invention

The equipment has a large range of utilization and good versatility.
[0008] Preferably, the lifting device includes an outer cover, the outer surface of the outer cover is fixedly connected to a connecting column, the outer surface of the connecting column is fixedly connected to a back cover, the inner surface of the back cover is fixedly connected to a sealing ring, the outer surface of the sealing ring is rotatably connected to a cutting device, an adjusting device is provided on the outside of the cutting device, a side plate is provided on the outside of the adjusting device, and in the process of contact between the outer wall of the pipe and the rolling device, the splint forces the movable plate to approach the pipe, and under the push of the reaction force, the roller slides along the slide grooves at both ends thereof, and the force storage spring and the telescopic rod shrink at the same time, further ensuring the fitting of the pipe.
[0009] Preferably, the cutting device includes a blade, the outer surface of the blade is fixedly connected to a turbofan, a U-shaped groove is opened in the wall of the blade, and the inside of the U-shaped groove is slidably connected to a centrifugal device. In the process of pushing the tube to move, the roller drives the rubber strip to rotate, and the rubber strip and the roller both adopt a concave design, which can effectively prevent the tube from slipping during rotation and movement and avoid idling and empty cutting. At the same time, the rubber strip can also absorb part of the vibration during the cutting process to ensure a smooth incision.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention sets up a machine body. When the equipment is in use, the pipe is inserted into the machine body, the bent rod lifts the end of the pipe, and then pushes the pipe to make the pipe slide inside the machine body. During this process, the cutting device cuts the pipe, and the storage device collects the debris generated during the cutting process. Under the action of gravity, the splashed debris slides along the inner surface of the baffle to the outside of the guide strip, and then is discharged from the through grooves on both sides of the guide strip to the inside of the storage box. When cutting, the cutting device sucks the floating debris into the inside of the cutting device, blows it into the inside of the storage box through the connecting pipe, and collects it in multiple directions, further reducing the probability of solid particles overflowing, thereby solving the problem that floating solid particles cannot be collected when traditional cutting machines cut pipes.
[0014] 2. The present invention provides a cutting device. When the equipment is in use, the rotating device rotates driven by the lifting device, and the inside of the lifting device also rotates at the same time. In this process, the lifting device drives the passive gear inside the rotating device to rotate. Since the passive gear is fixed on the outside of the swivel, when the swivel rotates along the inner wall of the machine body, it drives the clamping device to rotate together. The clamping device clamps and fixes the pipe. The clamping device cooperates with the cutting device inside the lifting device. The cutting device rotates to cut the pipe. The pipe also rotates at the same time driven by the clamping device, which shortens the pipe cutting time. Compared with traditional fixed pipe cutting, the pipe cutting efficiency can be further improved. Moreover, under the limiting effect of the clamping device, even if the pipe rotates during the cutting process, it will not cause large jumps and deviations. On the premise of shortening the cutting time, the cutting accuracy can also be further guaranteed.
[0015] 3. The present invention provides a clamping device. When the device is in use, the pipe rolls along the outer surface of the rolling device. The compression spring makes the two clamps always keep a tendency to move away from each other. The nut outside the screw is used to control the initial deformation of the compression spring, thereby controlling the clamping force of the two rolling devices. The base ensures that the clamping device can be fixed on the rotating ring. Since the opening angle of the two rolling devices can be adjusted, within the range allowed by the clamping device, it can ensure that pipes of different diameters are always fitted on the outside of the clamping device. The device has a large available range and good versatility. In addition, in the process of contact between the outer wall of the pipe and the rolling device, the clamp forces the movable plate to approach the pipe. Under the push of the reaction force, the roller slides along the slide grooves at both ends thereof, and the force storage spring and the telescopic rod shrink at the same time, further ensuring the fitting of the pipe. In the process of pushing the pipe to move, the roller drives the rubber strip to rotate. The rubber strip and the roller are both concave in design, which can effectively prevent the pipe from slipping during rotation and movement, and avoid idling and empty cutting. At the same time, the rubber strip can also absorb part of the vibration during the cutting process to ensure a smooth incision.
[0016] 4. The present invention is provided with a lifting device. When the equipment is in use, the cutting device rotates driven by the adjusting device, the outer cover is fixed to the back cover by the connecting column, the sealing ring inside the back cover remains stationary during the operation of the equipment, and the blade inside the cutting device drives the turbofan to slide along the inner cavity of the sealing ring. According to Bernoulli's principle, the fluid has a low pressure where the flow rate is large. When the turbofan rotates, the air pressure inside the sealing ring is much lower than the external air pressure, and the inclined side of the turbofan will also push the air to be injected into the interior of the connecting pipe. The dust mixed in the air enters the interior of the storage box through the connecting pipe, and the side panels intercept the large particles of debris splashing laterally.
[0017] 5. The present invention provides a cutting device and a centrifugal device. When the device is in use, the blade rotates at high speed. During this process, the centrifugal device inside the U-shaped groove is thrown out by the centrifugal force, and the slide bar slides along the inner wall of the blade. The locking bolt prevents the slide bar from falling off. The guide wheel prevents the slide bar from swinging and breaking while providing lateral support. The cutting disc and the blade participate in cutting. When the blade rotates, the diameter of the entire cutting device increases due to the throwing out of the centrifugal device. The higher the rotation speed, the greater the extension of the centrifugal device and the greater the cutting depth. The rotation speed can be used to directly control the cutting depth of the pipe. In addition, the centrifugal device adopts a flexible connection. When it contacts the pipe, it can pre-cut the outer surface of the pipe. Then the blade performs secondary cutting along the groove opened in advance by the centrifugal device, thereby avoiding the jamming and interruption of the single cutter head due to thermal expansion and contraction and resistance during long-term cutting, thereby improving the service life.
[0018] 6. The present invention provides an adjustment device. When the equipment is in use, the rotating rod on one side of the connecting plate uses a collar to control the meshing and separation of the active gear and the passive gear. With long-term use, a gap will be generated between the active gear and the passive gear due to wear, affecting the normal transmission efficiency. The rotating rod presses down the collar to reduce the gap and ensure normal transmission. The hollow shaft rotates under the drive of the external motor, and the turbofan rotates. Since one end of the hollow shaft is exposed, the outside air is sucked into the interior of the hollow shaft, and then enters the space outside the turbofan and the inside of the sealing ring through the through hole. The mixed air is sucked in and discharged, and the dust is blown into the interior of the connecting pipe and the storage box. The entire equipment can achieve front and rear linkage with a single motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The outer surface of the slide rod 44 is slidingly connected to the inner surface of the blade 40, the outer surface of the locking bolt 45 is threadedly connected to the inner surface of the blade 40, the outer surface of the slide rod 44 is rollingly connected to the outer surface of the guide wheel 46, the outer surface of the guide wheel 46 is rollingly connected to the inner surface of the U-shaped groove 42, the outer surface of the cutting disk 47 is fixedly connected to the inner surface of the slide rod 44, the turbofan 41 is located inside the sealing ring 33, the outer surface of the side plate 36 is fixedly connected to the outer surface of the outer cover 30, and the outer surface of the blade 40 is rotatably connected to the inner surface of the outer cover 30.
[0030] The adjusting device 35 includes a connecting plate 50, the inner surface of which is threadedly connected to a rotating rod 51, the bottom end of which is rotatably connected to a collar 52, the inner surface of which is rotatably connected to a hollow shaft 53, the outer surface of which is fixedly connected to a driving gear 54, a through hole 55 is provided in the wall of the hollow shaft 53, the outer surface of the hollow shaft 53 is slidably connected to the inner surface of the connecting plate 50, the lower surface of the connecting plate 50 is fixedly connected to the outer surface of the body 1, and the through hole 55 is located inside the sealing ring 33.
[0031] When the equipment is in use, the pipe is inserted into the body 1, the bending rod 4 lifts the end of the pipe, and then pushes the pipe to make it slide inside the body 1. During this process, the cutting device 3 cuts the pipe, and the storage device 2 collects the debris generated during the cutting process. Under the action of gravity, the splashed debris slides along the inner surface of the baffle 6 to the outside of the guide bar 7, and then is discharged from the through grooves on both sides of the guide bar 7 to the inside of the storage box 5. When cutting, the cutting device 3 sucks the floating debris into the inside of the cutting device 3, blows it into the inside of the storage box 5 through the connecting pipe 8, and collects it in multiple directions, further reducing the probability of solid particles overflowing, and solves the problem that floating solid particles cannot be collected when the traditional cutting machine cuts the pipe.
[0032] The rotating device 10 rotates under the drive of the lifting device 11, and the interior of the lifting device 11 also rotates at the same time. During this process, the lifting device 11 drives the passive gear 13 inside the rotating device 10 to rotate. Since the passive gear 13 is fixed on the outside of the swivel 12, when the swivel 12 rotates along the inner wall of the body 1, it drives the clamping device 14 to rotate together. The clamping device 14 clamps and fixes the pipe. The clamping device 14 cooperates with the cutting device 34 inside the lifting device 11. The cutting device 34 rotates to cut the pipe. The pipe also rotates at the same time under the drive of the clamping device 14, which shortens the pipe cutting time. Compared with traditional fixed pipe cutting, the efficiency of pipe cutting can be further improved. Moreover, under the limiting effect of the clamping device 14, even if the pipe rotates during the cutting process, it will not produce large jumps and deviations. On the premise of shortening the cutting time, the cutting accuracy can also be further guaranteed.
[0033] The pipe rolls along the outer surface of the rolling device 19, and the compression spring 18 makes the two clamps 16 always keep the tendency to move away from each other. The initial deformation of the compression spring 18 is controlled by the nut outside the screw 17, thereby controlling the clamping force of the two rolling devices 19. The base 15 ensures that the clamping device 14 can be fixed on the swivel 12. Since the opening angle of the two rolling devices 19 can be adjusted, within the range allowed by the clamping device 14, it can ensure that pipes of different diameters are always attached to the outside of the clamping device 14. The equipment has a wide range of application and good versatility. Moreover, in the process of the outer wall of the pipe contacting with the rolling device 19, the clamping plate 16 forces the movable plate 20 to approach the pipe. Under the push of the reaction force, the roller 23 slides along the slide grooves at both ends thereof, and the force storage spring 22 and the telescopic rod 21 shrink at the same time, further ensuring the fit of the pipe. In the process of pushing the pipe to move, the roller 23 drives the rubber strip 24 to rotate. Both the rubber strip 24 and the roller 23 adopt an inwardly concave design, which can effectively prevent the pipe from slipping during rotation and movement and avoid idling and empty cutting. At the same time, the rubber strip 24 can also absorb part of the vibration during the cutting process to ensure a smooth incision.
[0034] The cutting device 34 rotates driven by the adjusting device 35, the outer cover 30 is fixed to the back cover 32 by the connecting column 31, the sealing ring 33 inside the back cover 32 remains stationary during the operation of the equipment, and the blade 40 inside the cutting device 34 drives the turbofan 41 to slide along the inner cavity of the sealing ring 33. According to the Bernoulli principle, the fluid has a low pressure where the flow rate is high. When the turbofan 41 rotates, the air pressure inside the sealing ring 33 is much lower than the external air pressure, and the inclined side of the turbofan 41 will also push the air to be injected into the connecting pipe 8. The dust mixed in the air enters the interior of the storage box 5 through the connecting pipe 8, and the side plate 36 intercepts the large particles of debris splashing laterally.
[0035] The blade 40 rotates at high speed. During this process, the centrifugal device 43 inside the U-shaped groove 42 is thrown out by the centrifugal force, and the slide bar 44 slides along the inner wall of the blade 40. The locking bolt 45 prevents the slide bar 44 from falling off. The guide wheel 46 prevents the slide bar 44 from swinging and breaking while providing lateral support. The cutting disc 47 and the blade 40 participate in cutting. When the blade 40 rotates, the centrifugal device 43 is thrown out, and the diameter of the entire cutting device 34 increases. The higher the speed, the greater the extension of the centrifugal device 43 and the greater the cutting depth. The speed can be used to directly control the cutting depth of the pipe. In addition, the centrifugal device 43 adopts a flexible connection. When it contacts the pipe, it can pre-cut the outer surface of the pipe. Then the blade 40 performs secondary cutting along the groove opened in advance by the centrifugal device 43, thereby avoiding the jamming and interruption of the single cutter head due to thermal expansion and contraction and resistance during long-term cutting, thereby improving the service life.
[0036] The rotating rod 51 on one side of the connecting plate 50 uses the collar 52 to control the meshing and separation of the driving gear 54 and the driven gear 13. With long-term use, a gap will be generated between the driving gear 54 and the driven gear 13 due to wear, affecting the normal transmission efficiency. The rotating rod 51 presses down the collar 52 to reduce the gap and ensure normal transmission. The hollow shaft 53 rotates under the drive of the external motor, and the turbofan 41 rotates. Since one end of the hollow shaft 53 is exposed, the outside air is sucked into the interior of the hollow shaft 53, and then enters the space outside the turbofan 41 and the inside of the sealing ring 33 through the through hole 55. The mixed air is sucked in and discharged, and the dust is blown into the connecting pipe 8 and the interior of the storage box 5. The entire device can achieve front and rear linkage using a single motor.
