Description

Technical Field

[0001] This utility model relates to the field of pipe cutting and processing technology, specifically to a cutting device for irregularly shaped HDPE pipes. Background Technology

[0002] Irregularly shaped HDPE pipes refer to high-density polyethylene (HDPE) pipes that are processed into non-standard shapes through specific processes. They have excellent wear resistance, corrosion resistance, and long service life, and are widely used in agriculture, packaging, medical, and electronics industries.

[0003] For example, CN218341140U relates to an adaptive high-precision cutting device for irregular pipes, including an mounting ring groove and an inner groove. The inner groove is formed on one side surface of the mounting ring groove, and teeth are formed on the inner wall of the mounting ring groove. A sliding groove is formed on one side surface of the inner groove, and an arc-shaped slider is slidably connected inside the sliding groove.

[0004] This cutting device uses a movable box and springs. When cutting irregularly shaped pipes, the pipes can be fixed to the top of the support. As the saw disc rotates, the springs constantly apply pressure to the saw disc, and the bottom wheel always abuts against the outer contour of the irregularly shaped pipe. This causes the guide telescopic rod to extend and retract along the outer contour of the irregularly shaped pipe, allowing the saw disc to automatically adjust the cutting position according to the outer wall of the irregularly shaped pipe. However, in pipe assembly and installation, in order to reduce welding deformation and stress concentration, improve structural strength, and ensure construction safety, the pipes are generally beveled to form V-shaped / U-shaped bevels. The aforementioned cutting device cannot adjust the angle between the pipe and the saw disc when fixing the pipe, making it impossible to perform beveled cutting, thus affecting the cutting effect of the pipe. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the pipe cannot be cut at an angle due to the inability to adjust the angle between the pipe and the saw blade.

[0006] The purpose of this utility model is to provide a cutting device for irregularly shaped HDPE pipes, which can achieve the effect of bevel cutting of irregularly shaped HDPE pipes by adjusting the angle between the pipe and the saw blade when fixing the irregularly shaped HDPE pipe.

[0007] To achieve the above objectives, this utility model provides a cutting device for irregularly shaped HDPE pipes, including a processing table and a fixing body and a cutting body disposed on the processing table;

[0008] The processing table includes a base plate and a vertical plate located at the top center of the base plate. The vertical plate has an opening in the center for irregularly shaped HDPE pipes to pass through, and adapters are rotatably connected to both ends of the vertical plate.

[0009] The fixing body includes an outer ring and a contact structure disposed inside the outer ring. One end of the outer ring is connected to the adapter frame, and the contact structure is used to fix the irregular HDPE pipe.

[0010] The cutting body includes a cutting structure located at the top of the vertical plate and a locking structure slidably connected to the cutting structure. The locking structure is used to fix the adapter frame.

[0011] After the irregularly shaped HDPE pipe is passed through the outer ring and the port, it is fixed by the contact structure. Then, the adapter is rotated to tilt the irregularly shaped HDPE pipe. Subsequently, the cutting structure moves down to cut the irregularly shaped HDPE pipe. When the cutting structure moves down, it drives the locking structure to slide into contact with the adapter, so that the adapter cannot rotate. This can prevent the cutting structure from being damaged or the cutting quality from being affected by the change of the angle between the irregularly shaped HDPE pipe and the cutting structure during cutting.

[0012] As a further improvement to this technical solution, an inner ring is provided on the inner side of the outer ring, and the contact structure includes multiple bushings disposed on the inner wall of the inner ring. A first turntable is rotatably connected to one end of the bushing away from the inner ring. A first movable plate is inserted and fitted inside the bushing. One end of the first movable plate passes through the first turntable and is connected to a pressure plate. The first movable plate is threadedly connected to the first turntable.

[0013] Furthermore, the first movable plate is rotatably connected to the pressure plate. Rotating the first turntable causes the first turntable to drive the first movable plate to extend outward from inside the bushing until the first movable plate drives the pressure plate to contact the surface of the irregular HDPE pipe.

[0014] As a further improvement to this technical solution, the outer wall of the inner ring is rotatably connected to the inner wall of the outer ring, and the outer wall of the inner ring is provided with several teeth. The two ends of the outer ring are rotatably connected to a second turntable. The second turntable is located inside the outer ring and is threadedly connected to a second movable plate. One end of the second movable plate is engaged with the inner ring. Rotating the second turntable causes the second turntable to drive the second movable plate to move towards the inner ring and lock the inner ring.

[0015] As a further improvement to this technical solution, the cutting structure includes a hydraulic body and a lifting plate disposed at the top of the vertical plate. The bottom end of the hydraulic body is connected to the lifting plate, and a motor is disposed at the bottom of the lifting plate. The motor is connected to the saw blade.

[0016] Furthermore, lifting grooves are provided on both sides of the inner wall of the upright plate, and the two ends of the lifting plate are located in the lifting grooves and are slidably connected to the lifting grooves up and down.

[0017] Furthermore, the bottom of both ends of the lifting plate is provided with plate grooves, and the locking structure includes a clamping plate that is slidably connected to the inner wall of the vertical plate. Plate shafts are provided on both sides of the clamping plate, and the plate shafts are located in the plate grooves. The clamping plate and the lifting plate are slidably connected through the plate shafts and plate grooves. A transfer shaft is provided in the middle of the transfer frame, and gears are provided on the side wall of the transfer shaft. When the hydraulic body drives the saw blade to cut the irregular HDPE pipe through the lifting plate, the two ends of the lifting plate simultaneously drive the clamping plate to slide along the inner wall of the vertical plate, so that the clamping plate contacts and locks the gear.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. In this shaped HDPE pipe cutting device, the shaped HDPE pipe is fixed by a contact structure. Then, the adapter is rotated to tilt the shaped HDPE pipe, changing the angle between the shaped HDPE pipe and the cutting structure. This facilitates bevel cutting of the shaped HDPE pipe. Furthermore, when the hydraulic fluid drives the saw blade to cut the shaped HDPE pipe through the lifting plate, the two ends of the lifting plate simultaneously drive the clamping plates to slide along the inner wall of the vertical plate. This causes the clamping plates to contact and lock the gears, fixing the adapter and keeping the angle between the shaped HDPE pipe and the saw blade constant. This prevents damage to the saw blade or affects the cutting quality of the shaped HDPE pipe.

[0020] 2. In this shaped HDPE pipe cutting device, after the contact structure completes the fixation of the shaped HDPE pipe, it drives the shaped HDPE pipe to rotate inside the outer ring. After the surface of the shaped HDPE pipe to be cut faces the cutting structure, the second turntable is rotated, so that the second turntable drives the second movable plate to move towards the inner ring and contact the inner ring. That is, the second movable plate locks the inner ring by meshing, so that the inner ring can no longer rotate, ensuring the fixation of the shaped HDPE pipe during cutting.

[0035] Please see Figures 1-7As shown, this embodiment provides a cutting device for irregularly shaped HDPE pipes, including a processing table 1 and a fixing body 2 and a cutting body 3 disposed on the processing table 1;

[0036] The processing table 1 includes a base plate 11 and a vertical plate 12 located at the top center of the base plate 11. The vertical plate 12 has an opening in the center for irregularly shaped HDPE pipes to pass through, and adapter frames 13 are rotatably connected to both ends of the vertical plate 12.

[0037] The fixing body 2 includes an outer ring 21 and a contact structure 23 disposed inside the outer ring 21. One end of the outer ring 21 is connected to the adapter frame 13, and the contact structure 23 is used to fix the irregular HDPE pipe.

[0038] The cutting body 3 includes a cutting structure disposed at the top of the vertical plate 12 and a locking structure slidably connected to the cutting structure. The locking structure is used to fix the adapter 13.

[0039] After the irregularly shaped HDPE pipe passes through the outer ring 21 and the opening, it is fixed by the contact structure 23. Then, the adapter 13 is rotated to tilt the irregularly shaped HDPE pipe, so that the angle between the irregularly shaped HDPE pipe and the cutting structure changes, making it easier to cut the irregularly shaped HDPE pipe at an angle. Subsequently, the cutting structure moves down to cut the irregularly shaped HDPE pipe. When the cutting structure moves down, the cutting structure drives the locking structure to slide into contact with the adapter 13, so that the adapter 13 cannot rotate. This can prevent the cutting structure from being damaged or the cutting quality from being affected by the change in the angle between the irregularly shaped HDPE pipe and the cutting structure during cutting.

[0040] The above structure is disclosed below:

[0041] First, the irregularly shaped HDPE pipe needs to be fixed. An inner ring 22 is provided inside the outer ring 21. The contact structure 23 includes multiple bushings 231 set on the inner wall of the inner ring 22. The end of the bushing 231 away from the inner ring 22 is rotatably connected to a first turntable 232. A first movable plate 233 is inserted into the bushing 231. One end of the first movable plate 233 passes through the first turntable 232 and is rotatably connected to a pressure plate 234. The first movable plate 233 and the first turntable 232 are threaded together to hold the irregularly shaped HDPE pipe in place. After one end of the pipe passes through the outer ring 21 and the opening, the first turntable 232 is rotated, causing the first turntable 232 to drive the first movable plate 233 to extend outward from the bushing 231 until the first movable plate 233 drives the pressure plate 234 to contact the surface of the irregular HDPE pipe. The rotational connection between the first movable plate 233 and the pressure plate 234 allows the pressure plate 234 to deflect accordingly when it contacts the irregular surface of the irregular HDPE pipe, thereby better fixing the irregular HDPE pipe.

[0042] After the irregular HDPE pipe is fixed, in order to facilitate the rotation of the irregular HDPE pipe, the outer wall of the inner ring 22 is rotatably connected to the inner wall of the outer ring 21, and the outer wall of the inner ring 22 is provided with several teeth. The two ends of the outer ring 21 are rotatably connected to the second turntable 24. The second turntable 24 is located inside the outer ring 21 and is threadedly connected to the second movable plate 241. One end of the second movable plate 241 is engaged with the inner ring 22. After the contact structure 23 has fixed the irregular HDPE pipe, it can drive the irregular HDPE pipe to rotate inside the outer ring 21. After the surface of the irregular HDPE pipe to be cut is facing the cutting structure, the second turntable 24 is rotated, so that the second turntable 24 drives the second movable plate 241 to move towards the inner ring 22 and contact the inner ring 22. That is, the second movable plate 241 locks the inner ring 22 by meshing, so that the inner ring 22 can no longer rotate, ensuring the fixation of the irregular HDPE pipe during cutting.

[0043] After fixing the irregular HDPE pipe and adjusting the surface to be cut, rotate the adapter 13 to change the angle between the irregular HDPE pipe and the cutting structure. Then, the cutting structure cuts the irregular HDPE pipe. Specifically, the cutting structure includes a hydraulic body and a lifting plate 31 set at the top of the vertical plate 12. The bottom of the hydraulic body is connected to the lifting plate 31. A motor is set at the bottom of the lifting plate 31. The motor drives the saw blade 32. The hydraulic body drives the lifting plate 31 to move down, which in turn drives the saw blade 32 to move down. The motor drives the saw blade 32 to rotate and cut the irregular HDPE pipe.

[0044] To ensure stable cutting of irregularly shaped HDPE pipes by the saw blade 32 during cutting, lifting grooves are provided on both sides of the inner wall of the vertical plate 12. The lifting plate 31 is located within these lifting grooves and is slidably connected vertically. This vertical sliding connection allows the saw blade 32 to move only vertically, preventing horizontal displacement. Furthermore, to prevent changes in the angle between the irregularly shaped HDPE pipe and the saw blade 32 during cutting, which could damage the saw blade 32 or affect cutting quality, grooves 311 are provided at the bottom of both ends of the lifting plate 31. The locking structure includes a clamping plate 121 slidably connected to the inner wall of the vertical plate 12. Plate shafts 122 are provided on both sides of the clamping plate 121, located within the grooves 311. The clamping plate 121 and the lifting plate 31 are slidably connected via the plate shafts 122 and the grooves 311. A transfer shaft 131 is provided in the middle of the adapter frame 13, and a gear 132 is provided on the side wall of the transfer shaft 131. In the initial state, the clamping plate 121 does not contact the gear 132, so that the adapter frame 13 can rotate around the transfer shaft 131 as the axis, causing the irregular HDPE pipe to tilt, so that the angle between the irregular HDPE pipe and the saw blade 32 changes. When the hydraulic body drives the saw blade 32 to cut the irregular HDPE pipe through the lifting plate 31, the two ends of the lifting plate 31 simultaneously drive the clamping plate 121 to slide along the inner wall of the vertical plate 12, so that the clamping plate 121 contacts and clamps the gear 132, fixing the adapter frame 13 so that the adapter frame 13 cannot rotate, that is, the angle between the irregular HDPE pipe and the saw blade 32 remains unchanged, thereby avoiding damage to the saw blade 32 or affecting the cutting quality of the irregular HDPE pipe by the saw blade 32.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
