Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a clamping and cutting device for high-pressure composite pipes. Background Art

[0002] High-pressure composite pipes are produced in continuous lengths of several thousand meters, and need to be delivered in lengths ranging from fifty to several hundred meters. Therefore, during the production process, the longer high-pressure composite pipes need to be cut and pipe joints installed at both ends. Traditionally, pipe joint installation methods involve manually rolling the composite pipe on the reel into predetermined lengths and cutting it with a manual electric saw. The rolled composite pipe is then placed on the ground, and the pipe joints are hammered in and installed at each end. While this method is simple, the hammer's strong impact during installation can easily cause friction between the composite pipe and the ground, damaging the surface and potentially causing quality and safety issues. Therefore, a clamping device is required to hold the composite pipe joint in the air while the joint is manually installed. However, commonly used clamping devices cannot effectively clamp composite pipes of various sizes, making them prone to loose clamping. Furthermore, the clamping device has a single function and is inconvenient to move. Utility Model Content

[0025] See also Figures 1 to 5As shown, a high-pressure composite pipe clamping and cutting device is shown, in which a first cylinder frame 2 is installed at one end of a base 1, a second cylinder frame 3 is installed at the other end, and a third cylinder frame 4 is installed in the middle position; a first cylinder 5 and a second cylinder 6 are respectively installed on the first cylinder frame 2 and the second cylinder frame 3, and the first cylinder 5 and the second cylinder 6 have exactly the same structure; the output ends of the first cylinder 5 and the second cylinder 6 are respectively installed with the same clamping mechanism 9; the first cylinder 5 can push out the clamping mechanism 9, and similarly, the second cylinder 6 can also push out the clamping mechanism 9; when the first cylinder 5 and the second cylinder 6 are started at the same time, the two clamping mechanisms 9 will move relative to each other at the same time to clamp the high-pressure composite pipe; a third cylinder 7 is installed through the bottom of the third cylinder frame 4, and a lifting mechanism 8 is installed at the output end of the third cylinder 7, which can drive the lifting mechanism 8 to lift or lower; rubber pads are respectively installed at both ends of the lifting mechanism 8 to protect the outer wall of the composite pipe from being scratched.

[0026] The first cylinder 5 includes a piston 51 and a cylinder body; the end of the piston 51 is connected to the clamping mechanism 9; a blind hole is provided at the end of the piston 51; a spring 52 is installed at the bottom of the blind hole, and a slidable sliding shaft 53 is installed at the front end of the blind hole; one end of the sliding shaft 53 is connected to one end of the spring 52; the clamping mechanism 9 includes an external fixing part 91, a first clamping part 92, a second clamping part 93, a tensioning part 94, and a pull rod 95; the end of the piston 51 is fixed to the middle end of the external fixing part 91; the second clamping parts 93 are riveted on both sides of the upper and lower ends of the external fixing part 91, and the riveting is a movable riveting and can be rotated at the connection; a pull rod 95 is installed between two adjacent two of the four second clamping parts 93; when the pull rod 95 is pulled, the four second clamping parts 93 rotate and close around the riveted part in pairs to clamp the composite pipe ; The outer side of the first clamping piece 92 is connected to the sliding shaft 53; the first clamping piece 92 has tensioning pieces 94 riveted on both sides of the upper and lower ends, and the riveting is movable riveting and can rotate at the connection; the other end of the tensioning piece 94 is riveted to the pull rod 95, and similarly, the riveting is movable riveting and can rotate at the connection; when the first clamping piece 92 is in contact with the outer wall of the composite tube, the piston 51 continues to be pushed out, the tensioning piece 94 will pull the pull rod 95 and at the same time drive the second clamping piece 93, and the ends of the second clamping piece 93 will respectively move closer to the outer wall of the composite tube; when the piston 51 continues to be pushed out, the sliding shaft 53 will move toward one side of the cylinder body and at the same time compress the spring 52, which will react to the sliding shaft 53 and the first clamping piece 92, playing a shock absorbing role and reducing the risk of damaging the outer surface of the composite tube during the clamping process. The tensioning member 94 is an elastic component. When the composite pipe is clamped, it will deform and pull the pull rod. After deformation, the tensioning member 94 will fit tightly against the composite pipe. The inner sides of the first clamping member 92 and the tensioning member 94 are coated with rubber material. During the process of clamping the composite pipe, the rubber coating contacts the composite pipe to ensure that the outer wall of the composite pipe is not scratched.

[0027] A fixing seat 10 is installed on the first cylinder frame 2; a rotatable cutting mechanism 11 is installed on one side of the fixing seat 10; the cutting mechanism 11 can be opened separately. If it is necessary to split the roll, the clamping mechanism 9 can be used to clamp it, and then the cutting mechanism can be opened manually and the cutting mechanism handle can be pulled to slowly lower the cut composite pipe.

[0028] The base 1 is a trolley structure, which can be easily moved to the place where the roll cutting or pipe joint installation is required; a number of support seats 101 are spirally installed at the bottom of the base 1, and the support seats 101 can be rotated to the trolley to lift up, and will not shake when in use.

[0029] The working process of the present invention is as follows: when the high-pressure composite pipe clamping and cutting device is used, the trolley is moved to the use position, and then the support seat 101 is rotated to lift the trolley; the composite pipe that needs to be rolled or installed with the pipe joint is manually placed on the rubber pads at both ends of the jacking mechanism 8, and the third cylinder 7 is turned on. The third cylinder 7 will drive the composite pipe on the jacking mechanism 8 to rise, and stop after rising to the clamping position of the clamping mechanism 9; the first cylinder 5 and the second cylinder 6 are started synchronously. At this time, the pistons 51 of the first cylinder 5 and the second cylinder 6 move relative to each other and push the clamping mechanism 9 to move relative to each other; when the composite pipe is to be clamped, the inner side of the first clamping piece 92 first contacts the outer wall of the composite pipe, and the piston 51 continues to move. When the inner sides of the first clamping pieces 92 on both sides contact the outer wall of the composite pipe, the sliding shaft 53 will move toward one side of the cylinder body, and the sliding shaft 53 will compress the spring 52 to achieve a shock absorbing effect; in the process of gradual clamping of the clamping mechanism 9, the sliding shaft 53 will move toward the cylinder body. When the cylinder body moves on one side, it will pull the tensioning member 94, and the tensioning member 94 will pull the pull rod 95, and the pull rod 95 will drag the second clamping member 93 to bend toward the center of the composite pipe. At this time, the four upper and lower points of the composite pipe are clamped by the clamping mechanism 9, and the tensioning member 94 will also be deformed to fit tightly with the composite pipe; if the composite pipe needs to be cut, the cutting mechanism 11 is opened, and the cutting mechanism handle is manually held and pressed down to cut the composite pipe. Since the composite pipe is padded with a pad, the blade of the cutting mechanism 11 will not touch the lifting mechanism 8 after cutting downward; after cutting, the pipe joint can be installed directly by hand and tightened with a hammer; after installation, the reverse switch of the first cylinder 5 and the first cylinder 6 is opened synchronously, and the piston 51 will retract into the cylinder body. At this time, the clamping mechanism 9 will release the composite pipe, and the composite pipe falls onto the lifting mechanism 8. The composite pipe is removed manually to complete the operation; rotate the support seat 101 to make it rise, and then push the trolley to the appropriate position.

[0030] The utility model realizes the clamping of high-pressure composite pipes by means of a first cylinder, a second cylinder, and a clamping mechanism; realizes the clamping mechanism to clamp high-pressure composite pipes of different sizes and specifications by means of an external fixing member, a first clamping member, a second clamping member, a tensioning member, and a pull rod; by arranging a spring in the piston and coating the inner sides of the first clamping member and the tensioning member with rubber, shock absorption is achieved during the clamping process, thereby avoiding damage to the outer surface of the high-pressure composite pipe; by installing a cutting mechanism on the first cylinder frame, the high-pressure composite pipe is cut when it is rolled, and the pipe joint can be directly installed after cutting, which is convenient and quick; by setting the base into a trolley structure, the high-pressure composite pipe clamping and cutting device is conveniently moved, thereby increasing flexibility. The utility model has a simple structure, not only realizing the two functions of cutting and clamping, but also having high flexibility in use, avoiding damage to the outer surface of the high-pressure composite pipe during production, and improving production quality.
