Description

Technical Field

[0001] The present application relates to the field of production of reinforced composite plastic pipes, and in particular to a chip-free cutting machine for steel wire reinforced plastic pipes that can be applied to steel wire mesh reinforced polyethylene composite plastic pipes. Background Art

[0002] The main structure of the pure polyethylene pipe planetary cutting machine used in the prior art uses a carbide saw blade to cut the pipe. However, since the saw blade cuts in a milling manner, plastic and metal shavings will be generated during cutting (and plastic will generate static electricity). After a long period of work, they will adhere to the periphery of the machine and are difficult to clean, thus affecting the cutting effect. In addition, the wire mesh reinforced polyethylene composite plastic pipe uses high-strength and high-elastic steel wire, which causes great damage to the saw blade teeth. The high-speed rotating saw blade is easily interrupted by the steel wire, and the end face of the pipe is also prone to burrs and unevenness after cutting. The subsequent pipe sealing requires pipe grinding, which is time-consuming and labor-intensive.

[0003] The prior art, such as the Chinese utility model patent with patent number 201620799017.2 and the name "Dust-free Pipe Cutting Machine", has the following technical solution: The utility model discloses a dust-free pipe cutting machine, which includes: a rotating disk; a feed position adjustment device installed on the rotating disk; a cutting device installed on the feed position adjustment device and used for cutting pipes; a clamping device for clamping pipes; and a heated airflow generating device for blowing a heated airflow into the incision of the pipe clamped on the clamping device.

[0004] The above patent or prior art planetary cutting machine only has a pipe clamping mechanism at the pipe outlet end of the cutting follower trolley, or at the inlet end + outlet end, and there is no effective fixing mechanism near the cutting blade, so that the pipe between the front and rear clamps is longer. Since the wire mesh reinforced polyethylene composite plastic pipe is a flexible pipe, the cut section of the wire mesh reinforced polyethylene composite plastic pipe will be unstable when cutting.

[0036] Example 1

[0037] A chipless cutting machine for steel wire reinforced plastic pipes includes a frame 1, a track 2 and a cutting follower trolley 3, wherein the track 2 is connected to the frame 1, and the cutting follower trolley 3 moves on the track 2 through rollers, and the cutting follower trolley 3 includes a body 4, a blade 5 and a cutting clamping device 6, wherein the blade 5 and the cutting clamping device 6 are both located inside the body 4, and the cutting clamping device 6 for providing fixed clamping for the pipe located at the incision is installed at the front end of the blade 5. The cutting clamping device 6 provides support and clamping near the incision of the pipe to ensure stable cutting. The cutting clamping device 6 is installed inside the cutting follower trolley 3, near the cutting blade 5, to ensure that the pipe is not bent or shaken when subjected to force during cutting, and to ensure sufficient support force and stability during cutting.

[0038] Cutting action: After the pipe reaches the fixed length point, the cutting clamping device clamps the pipe, and the follower trolley moves with it. At the same time, the orbiting motor drives the blade 5 to rotate around the pipe axis. The blade 5 rotates driven by the blade rotating motor 18, and the hydraulic cylinder 20 gradually presses the blade 5 toward the center of the pipe. After the cutting is completed, the blade is retracted, the clamping is released, and the reset cylinder drives the cutting follower trolley 3 to return to the initial position to complete a cutting cycle.

[0039] Based on the existing cutting machine, the present application adds a cutting clamping device inside the trolley. The cutting clamping device is close to the cutting blade 5, which can ensure stability and increase the bearing capacity, so that the pipe will not bend or shake during cutting, and the pipe will not bounce when the cutting is completed.

[0040] Example 2

[0041] A chipless cutting machine for steel wire reinforced plastic pipes includes a frame 1, a track 2 and a cutting follower trolley 3, wherein the track 2 is connected to the frame 1, the cutting follower trolley 3 is located on the track 2 and moves on the track 2 through rollers, the cutting follower trolley 3 includes a body 4, a blade 5 and a cutting clamping device 6, the blade 5 and the cutting clamping device 6 are both located inside the body 4, and the cutting clamping device 6 for providing fixed clamping for the pipe at the incision is installed at the front end of the blade 5. The cutting clamping device 6 provides support and clamping near the incision of the pipe to ensure stable cutting. The cutting clamping device 6 is installed inside the cutting follower trolley 3, near the cutting blade 5, to ensure that the pipe is not bent or shaken when subjected to force during cutting, and to ensure sufficient support force and stability during cutting.

[0042] The cutting follower trolley 3 also includes a front-end guiding and stabilizing device 7 and a rear-end clamping device 8 for the pipe. The front-end guiding and stabilizing device 7 is located outside the front end of the trolley 4, and the rear-end clamping device 8 is located outside the rear end of the trolley 4. The front-end guiding and stabilizing device 7 and the rear-end clamping device 8 for the pipe are installed on the front and rear outer end surfaces of the cutting follower trolley 3. The front-end guiding and stabilizing device 7 prevents the front pipe from warping during pipe cutting and keeps it centered. The rear-end clamping device 8 ensures that the pipe remains stable after cutting.

[0043] The cutting clamping device 6 comprises a lower clamping seat 9 fixed on the cutting trolley 3 and an upper clamping block 10 movably connected to the cutting trolley 3, and the upper clamping block 10 can move relative to the cutting trolley 3. The lower clamping seat 9 and the cutting trolley 3 are fixedly connected, and the two move at the same time, and there is no relative movement between the lower clamping seat 9 and the cutting trolley 3; while the upper clamping block 10 is movably connected to the cutting trolley 3, and the movably connected mode is not limited to the existing movably connected modes such as sliding connection and hinge. The upper clamping block 10 realizes its relative movement with the cutting trolley 3 through the movably connected structure. Since the lower clamping seat 9 and the cutting trolley 3 are fixed to each other, the upper clamping block 10 can also realize relative movement relative to the lower clamping seat 9.

[0044] The lower clamping seat 9 is fixed on the wall panel 11 of the cutting follower trolley 3, and two linear guide rails 12 are arranged above the lower clamping seat 9. The two sides of the upper clamping block 10 are sleeved on the linear guide rails 12. A slider is installed on the back of the upper clamping block 10. The slider cooperates with the linear guide rails 12 to achieve movement. The upper clamping block 10 is connected to the clamping drive device 31, and the clamping drive device 31 drives the upper clamping block 10 to move along the linear guide rails 12. The slider cooperates with the linear guide rails 12 installed on the wall panel 11 of the cutting follower trolley 3, and can move up and down under the drive of the clamping drive device 31 to complete the clamping action.

[0045] The clamping drive device 31 is a clamping cylinder. When the clamping drive device 31 is installed horizontally: the output end of the clamping drive device 31 is connected to a hinge plate mechanism, and the hinge plate mechanism includes a first hinge plate 13 and a second hinge plate 14. The first hinge plate 13 is fixed to the wall panel 11 through a mounting seat 15, and the second hinge plate 14 is fixed to the upper clamp block 10. The output end of the clamping drive device 31 is connected to one end of the first hinge plate 13 and one end of the second hinge plate 14 at the same time. For small models with limited space, the clamping drive device 31 can also be installed horizontally. When installed horizontally, it can be connected to the upper clamp block 10 through the hinge plate mechanism.

[0046] When the clamping drive device 31 is installed vertically: the output end of the clamping drive device 31 is connected to the upper clamping block 10. When there is extra space for large models, the clamping drive device 31 can be installed vertically.

[0047] The top of the lower clamping seat 9 is provided with a lower semicircular specification block 16, and the bottom of the upper clamping block 10 is provided with an upper semicircular specification block 17. The two specification blocks are arranged up and down to form a circular space through which the pipe can pass. The specification block can be a nylon plate. The lower clamping seat 9 is fixedly connected to the wall plate 11 of the cutting follower trolley 3 by bolts to keep the lower busbar unchanged (that is, to ensure the maximum specification). One or more groups of semicircular nylon plates adapted to the pipe can be inserted into the lower clamping seat 9, so as to adapt to pipes of different specifications and keep the cutting center unchanged. The upper clamping block 10 is also equipped with one or more groups of semicircular nylon plates adapted to the pipe.

[0048] The blade 5 is connected to the blade rotation motor 18, which is fixed at one end of the blade motor mounting plate 19, and the other end of the blade motor mounting plate 19 is connected to the output end of the hydraulic cylinder 20. A hinge seat 21 is connected to the middle of the blade motor mounting plate 19, and the hydraulic cylinder 20 is fixed on the hydraulic cylinder mounting seat 22. A specification adjustment screw 23 is connected to the bottom of the hydraulic cylinder mounting seat 22. The feeding mode is changed from electric feeding to hydraulic feeding. The blade rotation motor 18 drives the blade 5 to rotate. At the same time, the hydraulic cylinder 20 pushes one end of the blade motor mounting plate 19 to move toward the outer side of the circumference. Since there is a hinge seat 21 in the middle of the blade motor mounting plate 19, the other end of the blade motor mounting plate 19 will move toward the center of the circumference at this time, so that the cutting action of the cutter on the reinforced plastic pipe is realized. The specification adjustment screw 23 is used to adjust the distance between the hydraulic cylinder mounting seat 22 and the blade motor mounting plate 19, and adjust the depth of the blade 5 cutting the reinforced plastic pipe.

[0049] The blade 5 is a carbide circular blade 5. The carbide circular blade 5 is selected and the active hard cutting method is adopted, so that there is no chip when cutting the plastic layer and the wire mesh metal layer, and the end is flat. Because the hard cutting force needs to be very large, strong support and clamping are required near the pipe cut.

[0050] The front-end guiding and stabilizing tube device 7 comprises a mounting frame 24 and a set of transverse centering rollers 25 and a set of longitudinal centering rollers 26 fixed on the mounting frame 24. The two sets of centering rollers adjust the four directions of the tube.

[0051] The transverse centering roller 25 includes two transversely arranged V-shaped wheels 27 and two longitudinally arranged screw rods 28. The two V-shaped wheels 27 are respectively located at the upper and lower parts of the fixed mounting frame 24, and the two screw rods 28 are respectively located at the left and right parts of the fixed mounting frame 24. The two ends of each V-shaped wheel 27 are respectively connected to a V-shaped wheel shaft 29, and the V-shaped wheel shaft 29 is threadedly connected to the adjacent screw rod 28. A handwheel 30 is connected to the top of each screw rod 28.

[0052] The longitudinal centering roller 26 includes two longitudinally arranged V-shaped wheels 27 and two transversely arranged screw rods 28. The two V-shaped wheels 27 are respectively located at the left and right parts of the fixed mounting frame 24, and the two screw rods 28 are respectively located at the upper and lower parts of the fixed mounting frame 24. The two ends of each V-shaped wheel 27 are respectively connected to a V-shaped wheel axle 29, and the V-shaped wheel axle 29 is threadedly connected to the adjacent screw rod 28.

[0053] Because of the cutting clamping device 6 in the follower carriage, the traditional clamping device is eliminated here, so it is adjusted to a guiding and stabilizing device for guiding and stabilizing the pipe. The screw rod 28 is a positive and negative thread. When the hand wheel 30 is turned, the positive and negative thread screw rod 28 drives the paired V-shaped wheels 27 to move closer to or away from the center of the pipe, completing the centering of the pipe.

[0054] like Figure 2 As shown, a revolving motor is installed on the top of the follower trolley, and the output shaft of the revolving motor has a sprocket. The follower trolley is arranged with a rotating cylinder on the periphery of the pipe axis (larger than the maximum pipe specification), and a large sprocket is installed on the rotating cylinder. There are rolling bearings between the rotating cylinder and the follower trolley. The sprocket on the output shaft of the revolving motor is connected to the large sprocket through a chain, which provides rotational power to the rotating cylinder. Thereby driving the blade 5 and the blade rotating motor 18 to rotate around the reinforced plastic pipe. In addition, a cylindrical brush is installed on the rotating cylinder, so that power can be provided to the cutting motor. The above structures are all existing technologies of planetary cutting machines and are not limited here.

[0055] Cutting action: After the pipe reaches the fixed length point, the cutting clamping device clamps the pipe, and the follower trolley moves with it. At the same time, the orbiting motor drives the blade 5 to rotate around the pipe axis. The blade 5 rotates driven by the blade rotating motor 18, and the hydraulic cylinder 20 gradually presses the blade 5 toward the center of the pipe. After the cutting is completed, the blade is retracted, the clamping is released, and the reset cylinder drives the cutting follower trolley 3 to return to the initial position to complete a cutting cycle.
