Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting, in particular to a pipe cutting and positioning device for PVC pipe production. Background Art

[0002] Most pipes are made of polymer materials, metal materials or fiber composite materials, and are widely used in the fields of electricity, construction, drainage and water supply. The final process of pipe forming includes essential grinding and fine grinding. For example, in the production line operation of PVC pipes, before the PVC pipes are cut by the cutting machine, they are often required to be clamped and fixed with a pipe clamping device to ensure that they will not jump before the next cutting operation can be carried out.

[0003] At present, when cutting or drilling PVC pipes, a simple homemade structure is basically used. However, for some larger pipe products, when a clamping device made of a simple structure is used, the processing quality will be low or even inferior products will be produced. When cutting the pipe, it is necessary to clamp and position both ends of the pipe. However, when cutting larger pipes, one end of the cut material is not clamped, and the material falls directly after cutting, which will cause the cut to bend as the gravity of one end of the pipe drops, making the bottom cut uneven. The fallen pipes need to be picked up again by workshop workers, which increases the workload, and direct falling will also cause collision damage. In addition, after the pipe is cut, it will curl up without clamping at both ends, affecting subsequent processing. There is no good processing positioning structure, and when the pipe to be processed is fed and pushed for processing, it only has the effect of clamping, and its periphery cannot be cleaned, and impurities cannot be removed, resulting in unstable clamping at the subsequent processing end.

[0048] See also Figure 3 , Figure 4 , Fig. 9 , Fig.10 and Fig.11 A second motor 35 is fixedly mounted on the top of the processing box 10 at the center of the bottom side of the fixed plate 30 by bolts, the top end of the first rotating rod 33 extends through the output end of the second motor 35, and the first gear 32 is fixed on the outer periphery of the first rotating rod 33;

[0049] An arc-shaped clamping plate 70 is fixedly installed at the center of one side of the top of the L-shaped connecting plate 54 by bolts, and a limiting column 71 is fixedly installed at the center of both ends of one side of the top of the arc-shaped clamping plate 70 by bolts, and a telescopic spring 72 is fixedly installed at the center of the inner bottom end of the limiting column 71 by bolts, and a support rod 73 movable in the limiting column 71 is fixedly installed between the top ends of the telescopic springs 72 by bolts, and a ball 74 is rotatably connected to the center of the top end of the support rod 73.

[0050] See also Figure 2 , Figure 3 and Fig.12 A third motor 80 is fixedly installed at the top center of the other side of the fixed disk 30 by bolts, and a processing ring 81 is fixedly installed at the center of the other side of the fixed disk 30 by bolts. A processing turntable 83 is movably connected to the processing ring 81 through a slider, and the output end of the third motor 80 is connected to a processing gear 84 movably meshed with the processing turntable 83 through a rotating shaft to realize rotation processing.

[0051] A processing plate 85 is fixedly installed at the top of one side of the processing turntable 83 by bolts, and an electric telescopic rod 86 is fixedly installed at the bottom center of the other end of the processing plate 85 by bolts. The distance can be adjusted to meet the processing and cutting requirements of pipe bodies 90 with different inner diameters. A processing and cutting frame 82 is fixedly installed at the bottom end of the electric telescopic rod 86 by bolts to achieve cutting and discharging of one end of the pipe body 90.

[0052] Working principle: the pipe body 90 is inserted into the movable disk 20 in sequence and enters the cleaning disk 40, and then enters the fixed disk 30 through the top of the limiting base 50, and then the third gear 22 is driven by the first motor 21 to rotate, and the third gear 22 is engaged to drive the clamping turntable 62 on the annular limiting seat 61 to rotate, and the clamping turntable 62 drives the arc clamping rod 64 under the push plate 65 to move through the arc movable groove 63, so that the L-shaped support seat 66 on the movable disk 20 drives the arc side plate 60 of the push plate 65 to clamp and fix one end of the pipe body 90, and then the first gear 32 is driven by the second motor 35 to rotate, and similarly, the L-shaped support seat 66 on the fixed disk 30 drives the arc side plate 60 on the push plate 65 to clamp and fix the other end of the pipe body 90, thereby achieving clamping and fixing of both ends of the pipe body 90;

[0053] The third motor 80 on the processing disk drives the processing gear 84 to rotate, and the processing gear 84 meshes to drive the processing turntable 83 on the processing ring 81 to rotate. During the rotation of the processing turntable 83, the processing plate 85 and the electric telescopic rod 86 drive the processing cutting frame 82 to perform rotational cutting processing on the outer periphery of the pipe body 90, and the operation is stable;

[0054] When the fixed plate 30 clamps one end of the pipe body 90, the first rotating rod 33 on the first gear 32 is driven by the second motor 35 to rotate, and the first rotating rod 33 drives the second bevel gear 34 at the top to rotate synchronously, and the second bevel gear 34 engages to drive the first bevel gear 53 in the limiting base 50 to rotate, and the first bevel gear 53 drives the positioning screw 52 on the bearing 51 to rotate stably during the rotation process, and the L-shaped connecting plate 54 on the positioning screw 52 drives the top arc clamping plate 70 to limit and support the two ends of the pipe body 90 under the action of the positioning rod 56 and the limiting groove 55, so that the telescopic spring 72 in the limiting column 71 is compressed under the action of the support rod 73 and the ball 74, so as to achieve the effect of limiting and supporting the pipe body 90;

[0055] When the cutting is completed, the second motor 35 is started to loosen and clamp the cut pipe body 90, and the cut pipe body 90 can be directly removed from between the arc-shaped side plates 60. During the loosening process, the first rotating rod 33 drives the arc-shaped clamping plate 70 to loosen and clamp the two ends of the pipe body 90 to a certain extent through the meshing of the bevel gears. However, at this time, the telescopic spring 72 in the limit column 71 is still in the power storage state, and the ball 74 of the support rod 73 still has the effect of limiting and supporting one end of the pipe body 90, so as to prevent the pipe body 90 from tipping over under the clamping of the falling fixed plate 30, affecting the subsequent feeding. The structure is ingenious and simple.

[0056] During the continuous feeding after cutting, the driving motor 15 is used to drive the movable block 13 and the movable disk 20 on the pushing frame 11 to push the tube body 90. One end of the tube body 90 moves horizontally and stably between the balls 74 to feed, so that the other end of the tube body 90 enters the fixed disk 30 to be clamped and fixed. When the movable screw 12 rotates to drive the tube body 90 on the movable disk 20 to push, it will drive the second gear 43 under the cleaning disk 40 to rotate stably in the rotating groove 42. The second gear 43 engages to drive the cleaning disk 40 on the cleaning ring 45 to rotate. The cleaning brush in the cleaning frame 47 in the cleaning disk 40 rotates and cleans the outer periphery of the tube body 90, and brushes off impurities on the outer periphery of the tube body 90, so that the subsequent fixed disk 30 is more stable in the process of clamping the tube body 90, and will not cause tilting or clamping damage, and the cleaning function performance is strong.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
