Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe processing, in particular to an automatic cutting device for corrugated pipe production. Background Art

[0002] With the rapid development of industrial automation, bellows, as an important industrial connector, has been widely used in chemical, electronic, medical and other fields. In the current industrial manufacturing and pipeline processing fields, bellows, as an important pipeline material, its cutting and processing process plays a vital role in production efficiency and product quality.

[0003] However, traditional metal bellows cutting methods often have problems such as cumbersome operation, low efficiency and unstable cutting quality. Traditional metal bellows cutting equipment usually adopts fixed clamps and cutting mechanisms, which are difficult to adapt to bellows of different diameters, resulting in complicated and inefficient operation process, and the clamping effect generally only exists on the surface. Under the pressure of the blade and the clamping effect of the clamp, the surface of the metal bellows is easily deformed. In addition, during the cutting process, the bellows is easily hollow inside and lacks support. After the surface is subjected to the pressure of the cutting blade, it may cause the surface to sag due to uneven force, affecting the cutting quality and product appearance. In the cutting process, there is also the problem that the cutting position happens to appear at the intersection of the protrusions and depressions on the surface of the bellows.

The inner support mechanism includes: a driving platform 16, a rotatable rotating platform 12 is arranged on the upper surface of the driving platform 16, and a small motor for driving the rotating platform 12 to rotate is arranged inside the driving platform 16;

[0039] The fixing mechanism also includes: an internal fixing cylinder 30, the internal fixing cylinder 30 is located at the center of the fixing box 11, the outer surface of the internal fixing cylinder 30 is sleeved with a rotating cylinder 31, the upper surface of the internal fixing cylinder 30 is fixedly installed with a connecting plate 32, the top surface of the connecting plate 32 is fixedly connected to the inner wall of the fixing box 11, the surface of the rotating cylinder 31 is also provided with a sliding groove 35 for facilitating the sliding of the connecting plate 32, the surface of the internal fixing cylinder 30 is provided with a plurality of retractable clamping rings 22, a movable protrusion 33 is fixedly installed on one side surface of the clamping ring 22, a fixed contact pressure block 34 for cooperating with the movable protrusion 33 to push the clamping ring 22 out is fixedly installed on the inner wall of the rotating cylinder 31, an engaging notch is provided on the bottom surface of the rotating cylinder 31, an engaging roller 28 is engaged with the bottom surface of the rotating cylinder 31, a driving motor 36 for driving the roller 28 to rotate is provided on one side surface of the engaging roller 28, and a pressure switch 37 is provided on the bottom surface of the driving motor 36, and the fixing mechanism also includes: a buffer box 21, The buffer box 21 is fixedly installed on the upper surface of the movable platform 6. The upper surface of the buffer box 21 is connected with a connecting top plate 25 through a rotating shaft. A folding sleeve 23 is arranged between the buffer box 21 and the connecting top plate 25. A plurality of buffer springs 29 are also arranged on the bottom surface of the connecting top plate 25. A limiting frame 27 is fixedly installed on the upper surface of the buffer box 21. The meshing roller 28 is located in the exposed opening opened in the center of the limiting frame 27. A coupling notch 26 matching with the limiting frame 27 is opened at the center of the connecting top plate 25. Two hydraulic telescopic rods 17 for driving the movable platform 6 to move are also arranged on one side surface of the working machine base 1. Two auxiliary stabilizing frames 7 are also fixedly installed on both side surfaces of the movable platform 6. A stabilizing groove matching with the auxiliary stabilizing frames 7 is opened on the upper surface of the working machine base 1. Two main meshing toothed belts 24 are also fixedly installed on one side surface of the movable platform 6. A fixed meshing disk 8 matching with the main meshing toothed belt 24 is also fixedly connected to the upper surface of the working machine base 1.

[0040] The buffer box 21 and the connecting top plate 25 are connected by a folding sleeve 23. The buffer spring 29 provides a buffering effect to protect the bellows from damage during the cutting process. After one end of the bellows enters the center of the fixed box 11, the connecting top plate 25 is driven down by the gravity of the bellows, and the rotating cylinder 31 is pressed down to engage with the meshing roller 28 below. During the pressing process, the pressure switch 37 is triggered. The pressure switch 37 controls the driving motor 36 to drive the rotating cylinder 31 to rotate on the surface of the internal fixed cylinder 30, and uses the fixed contact block 34 on the inner wall to contact the movable protrusion 33. , push out the clamp ring 22 to fix the surface of the bellows. After the pressure of the bellows is lost inside the fixing box 11, the clamp ring 22 will be retracted, and the movable platform 6 will be moved by the hydraulic telescopic rod 17. The auxiliary stabilizing frame 7 and the main meshing toothed belt 24 cooperate with the fixed meshing disk 8 to ensure the stability of the movable platform 6 during the movement. At the same time, because the main meshing toothed belt 24 and the side of the driving platform 16 are both in cooperation with the fixed meshing disk 8, when the hydraulic telescopic rod 17 drives the movable platform 6 to move, it will also drive the driving platform 16 to move in the opposite direction, so as to quickly fix and unload the bellows;

[0041] The inner support mechanism further includes: a contact plate 44, which is located on one side surface of the rotating platform 12, and a telescopic motor 48 is also provided inside the rotating platform 12, and a telescopic push rod 47 is provided on the output end of the telescopic motor 48, and a length scale is engraved on the surface of the telescopic push rod 47, and an inner support disk 46 is sleeved on the surface of the telescopic push rod 47, and a push ring for pushing out the inner support disk 46 is also sleeved on the surface of the telescopic push rod 47, and an inner push ring plate 45 is also fixedly installed on the end of the telescopic push rod 47;

[0042] The inner support mechanism drives the telescopic top rod 47 to extend and retract through the telescopic motor 48, thereby adjusting the position of the inner support plate 46. The inner top ring plate 45 supports the corrugated tube from the inside to prevent it from being sunken due to the force on the surface of the corrugated tube during the cutting process. The contact plate 44 ensures that the inner support plate 46 is in close contact with the inner wall of the corrugated tube. The small motor drives the rotating table 12 to rotate. After the corrugated tube is cut, the weight applied by the corrugated tube to the fixing mechanism is reduced, and the fixing effect inside the fixing mechanism is cancelled. After the fixing mechanism is separated from the inner support mechanism, the inner support mechanism can be rotated with the finished corrugated tube and put into the discharge assembly at the rear for discharge.

[0043] The cutting mechanism also includes: two detection light strips 41, the upper surface of the cutting disc 9 is fixedly connected with a connecting rod, the two detection light strips 41 are sleeved on the surface of the connecting rod, the side surface of the connecting rod is also fixedly installed with a laser rangefinder 42 for detecting the cutting length, and the upper surface of the rotating table 12 is also fixedly installed with an illuminated plate 43 that matches the laser rangefinder 42;

[0044] The two movable boxes 4 are movable and can be moved with the cutting mechanism to the working area between the fixed mechanism and the inner support mechanism for cutting during operation. The threaded rod 10 is driven by the brake motor to move the cutting seat 3 and the cutting disc 9 in the horizontal direction. The cutting disc 9 cuts the corrugated tube under the drive of the motor. The detection light belt 41 and the laser rangefinder 42 cooperate with the illuminated plate 43 to ensure the accuracy of the cutting length. The two detection light belts 41 are used to detect whether the cutting surface is flat to avoid the problem that the cutting surface is located between the raised position and the recessed position on the surface of the corrugated tube, which leads to poor cutting effect. When this happens, the supporting effect of the inner support mechanism can be cancelled, and the cutting disc 9 can be used to trim the end of the clamping end. The cutting surface is adjusted to a flat surface by trimming a section and cutting is performed. The laser rangefinder 42 can always observe the cutting length by cooperating with the illuminated plate 43 to prevent the problem of different lengths of finished products.

[0045] The material discharging assembly includes: a material discharging slide 13, the material discharging slide 13 is fixedly mounted on one side surface of the working machine base 1, a protective cover plate 14 is fixedly mounted on the upper surface of the material discharging slide 13, a material discharging conveyor belt 15 is arranged at the center of the material discharging slide 13, two loading cylinders 38 are arranged on the surface of the material discharging conveyor belt 15, and a touch switch 39 for triggering the movement of the material discharging conveyor belt 15 is arranged on one side surface of the material discharging conveyor belt 15;

[0046] After the corrugated tube is cut, the cut corrugated tube product is moved to the top of the unloading slide 13 by the internal support mechanism through rotation, and the fixing effect of the internal support mechanism is cancelled after reaching the specified position, so that the finished product slides down to the unloading conveyor belt 15 through the unloading slide 13. The protective cover plate 14 protects the corrugated tube from external interference during the transmission process, and prevents the corrugated tube from sliding out of the unloading assembly due to incorrect falling position. When the driving platform 16 moves with the finished product and approaches and contacts the touch switch 39, the unloading conveyor belt 15 starts to prepare for movement. After the driving platform 16 transfers the finished corrugated tube product to the loading cylinder 38, it leaves and cancels the contact with the touch switch 39 under the drive of the fixing mechanism. The touch switch 39 drives the unloading conveyor belt 15 to transmit, and transports the loading cylinder 38 loaded with the finished product downward, and at the lowest point, it flips with the movement of the unloading conveyor belt 15, pours out the finished product inside, and sends the empty loading cylinder 38 located at the bottom to the waiting position for preparation;

[0047] The guide assembly includes: two guide frames 5, the two guide frames 5 are respectively located on both sides of the feeding conveyor belt 2, and a plurality of small rollers 18 are arranged on the adjacent sides of the two guide frames 5. A double-axis motor 19 is also arranged inside the working machine base 1, and rotatable meshing screws 20 are arranged at both ends of the double-axis motor 19. The ends of the two meshing screws 20 are respectively meshed with the side surfaces of the two guide frames 5, and the two meshing screws 20 can be driven to rotate by the double-axis motor 19, so as to drive the two guide frames 5 to move inward or outward at the same time;

[0048] The feeding conveyor belt 2 is transported on the upper surface of the working machine base 1, and the corrugated tube raw material is transported from one end to the other end. The limiting guardrail ensures that the corrugated tube will not slip off the conveyor belt during transportation. The two guide frames 5 are located on both sides of the feeding conveyor belt 2. They are driven by the meshing screw 20 driven by the dual-axis motor 19 to rotate, so as to adjust the distance between the two guide frames 5 to adapt to corrugated tubes of different diameters. The small roller 18 on the guide frame 5 can help the corrugated tube to adjust its position during transportation and keep moving in a straight line before entering the processing area.

[0049] The working principle of the present invention is as follows: the feeding conveyor belt 2 is conveyed on the upper surface of the working machine base 1, and two guide frames 5 are located on both sides of the feeding conveyor belt 2. They are driven by the meshing screw 20 driven by the double-axis motor 19 to rotate, thereby adjusting the distance between the two guide frames 5 to adapt to the corrugated pipes of different diameters. The small roller 18 on the guide frame 5 can help the corrugated pipe to adjust its position during the transmission process;

[0050] The buffer box 21 and the connecting top plate 25 are connected by a folding sleeve 23. The buffer spring 29 provides a buffering effect to protect the bellows from damage during the cutting process. After one end of the bellows enters the center of the fixed box 11, the connecting top plate 25 is driven down by the gravity of the bellows, and the rotating cylinder 31 is pressed down to engage with the meshing roller 28 below, and the internal fixed contact block 34 is used to contact the movable protrusion 33, and the clamping ring 22 is pushed out to fix the surface of the bellows. After the pressure of the bellows is lost inside the fixed box 11, the clamping ring 22 will be retracted, and the movable platform 6 is moved by the hydraulic telescopic rod 17. The auxiliary stabilizing frame 7 and the main meshing toothed belt 24 cooperate with the fixed meshing disk 8 to ensure the stability of the movable platform 6 during the movement.

[0051] The inner support mechanism drives the telescopic top rod 47 to extend and retract through the telescopic motor 48, thereby adjusting the position of the inner support plate 46. The inner top ring plate 45 supports the inner side of the bellows to prevent it from being sunken due to the force on the surface of the bellows during the cutting process. The contact plate 44 ensures that the inner support plate 46 is in close contact with the inner wall of the bellows. The small motor drives the rotating table 12 to rotate. After the bellows is cut, the inner support mechanism can rotate with the finished bellows and put it into the discharge assembly at the rear for discharge.

[0052] The two movable boxes 4 are movable and can be moved with the cutting mechanism to the working area between the fixed mechanism and the inner support mechanism for cutting during operation. The threaded rod 10 is driven by the brake motor to move the cutting seat 3 and the cutting disc 9 in the horizontal direction. The cutting disc 9 cuts the corrugated pipe under the drive of the motor. The detection light belt 41 and the laser rangefinder 42 cooperate with the illuminated plate 43 to ensure the accuracy of the cutting length. The two detection light belts 41 are used to detect whether the cutting surface is flat to avoid the problem that the cutting surface is located between the raised position and the recessed position on the surface of the corrugated pipe, which leads to poor cutting effect.

[0053] After the corrugated tube is cut, the cut corrugated tube product is moved to the top of the unloading slide 13 through the internal support mechanism by rotation, and the fixing effect of the internal support mechanism is cancelled after reaching the specified position, so that the finished product slides through the unloading slide 13 to the unloading conveyor belt 15. The protective cover plate 14 protects the corrugated tube from external interference during the transmission process, and prevents the corrugated tube from sliding out of the unloading assembly due to incorrect falling position. When the driving platform 16 moves with the finished product and approaches and contacts the trigger switch 39, the unloading conveyor belt 15 starts to prepare for movement. After the driving platform 16 transfers the corrugated tube product to the loading cylinder 38, the trigger switch 39 drives the unloading conveyor belt 15 to transmit, and transports the loading cylinder 38 loaded with the finished product downward, and at the lowest point, it flips with the movement of the unloading conveyor belt 15, pours out the finished product inside, and sends the empty loading cylinder 38 at the bottom to the waiting position for preparation.
