[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. After being pressurized by blowers, compressors, pumps and boilers, the fluid flows from the high-pressure part of the pipeline to the low-pressure part.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, the utility model provides a reaming and expanding machine for pipe processing, comprising:

[0030] Support leg 1, an operating table 2 is fixedly installed on the top of the support leg 1, and a mounting plate 3 is fixedly installed on the left side of the top of the operating table 2;

[0031] The adjusting mechanism 4 is arranged on the top of the operating table 2;

[0032] The driving mechanism 5 is arranged on the left side of the operating table 2;

[0033] Among them, the adjustment mechanism 4 includes a limit plate 401, and there are two limit plates 401. The two limit plates 401 are respectively fixedly mounted on the left and right ends of the rear side of the top of the operating platform 2. The tops of the two limit plates 401 are fixedly mounted with baffles 402. The bottoms of the outer surfaces of the two limit plates 401 are movably connected with a bottom plate 403. The bottom end of the bottom plate 403 is movably connected to the top of the operating platform 2. A fixed plate 404 is fixedly mounted on the right side of the top of the bottom plate 403. A hydraulic cylinder 405 is fixedly mounted on the left end of the fixed plate 404. The right end of the hydraulic cylinder 405 passes through the fixed plate 404 and extends to the right side of the outer surface of the fixed plate 404. The upper and lower sides of the front end of the bottom plate 403 are respectively hinged with connecting plates 406 located inside the left end of the operating platform 2. There are two connecting plates 406 and they are symmetrical with each other about the center of the bottom plate 403. The connecting plates 406 will cause the bottom plate 403 to move.

[0034] When one ends of the two connecting plates 406 move toward each other, the other ends of the connecting plates 406 will generate a thrust on the bottom plate 403, pushing the bottom plate 403 to move with the fixed plate 404 and the hydraulic cylinder 405. The existence of the limit plate 401 and the baffle 402 can limit the movement of the bottom plate 403, thereby ensuring the stability of the movement of the bottom plate 403. In this way, the height of the hydraulic cylinder 405 can be adjusted, so that the tube expander can be easily aligned with the pipe to be expanded after the mold is replaced, thereby improving the convenience of using the tube expander.

[0035] The driving mechanism 5 includes:

[0036] The drive motor 501 is fixedly mounted on the left side of the bottom end of the operating table 2. The other end of the output shaft of the drive motor 501 is fixedly sleeved with a double-threaded rod 502. The top end of the double-threaded rod 502 passes through the operating table 2 and extends to the top of the outer surface of the operating table 2.

[0037] There are two movable blocks 503, which are respectively threadedly sleeved on the upper and lower sides of the outer surface of the double-threaded rod 502. The back surfaces of the two movable blocks 503 are movably connected to the upper and lower sides of the left end of the operating table 2, and the rear ends of the two movable blocks 503 are respectively hinged to the front ends of the two connecting plates 406;

[0038] The limiting rod 504 is two in number, and the two limiting rods 504 are movably sleeved on the inner surfaces of the left and right ends of the two movable blocks 503 respectively, and the outer surfaces of the two limiting rods 504 are fixedly sleeved on the inner surface of the left end of the operating table 2.

[0039] When the driving motor 501 is started, the double-threaded rod 502 will rotate, so that the two movable blocks 503 and the connecting plate 406 will move toward each other along the outer surface of the limiting rod 504.

[0040] Among them, a rectangular plate 6 is fixedly installed on the right end of the hydraulic cylinder 405, the left end of the rectangular plate 6 is movably connected to the bottom plate 403 and the right end of the fixed plate 404, and a hole expansion mold 7 is fixedly installed in the middle of the right end of the rectangular plate 6.

[0041] When the hydraulic cylinder 405 is activated, it will push the rectangular plate 6 to move with the hole-expanding die 7, thereby completing the hole-expanding operation.

[0042] Among them, the top of the mounting plate 3 is fixedly installed with a first fixed mold 8, the top of the mounting plate 3 is fixedly installed with a support plate 9 located on the rear side of the first fixed mold 8, the middle of the top of the support plate 9 is fixedly installed with a pneumatic cylinder 10, the bottom end of the pneumatic cylinder 10 passes through the support plate 9 and extends to the outside of the support plate 9 and is fixedly installed with a second fixed mold 11, and the top of the second fixed mold 11 is movably connected to the outer surface of the support plate 9.

[0043] When the pneumatic cylinder 10 is activated, the second fixed mold 11 will move toward the first fixed mold 8, thereby clamping and fixing the pipeline.

[0044] A stopper 12 is movably mounted on the right side of the top of the operating table 2 , a slider 13 is fixedly mounted on the bottom end of the stopper 12 , and the outer surface of the slider 13 is movably connected to the inner surface of the operating table 2 .

[0045] When the slider 13 moves, the stopper 12 will move together with it.

[0046] Among them, the middle part of the front end of the slider 13 is hinged with a connecting rod 14, the rear end of the connecting rod 14 is movably connected to the front end of the operating table 2, and the left end of the connecting rod 14 is hinged with a rotating rod 15, which will move the slider 13.

[0047] When the right end of the rotating rod 15 rotates with the left end of the connecting rod 14, the other end of the connecting rod 14 will generate a pulling force on the slider 13, pulling the slider 13 to move.

[0048] Among them, a power motor 16 is fixedly installed on the left side of the bottom end of the operating table 2, and a rotating shaft 17 is fixedly sleeved on the other end of the output shaft of the power motor 16. The outer surface of the rotating shaft 17 is fixedly sleeved on the inner surface of the left end of the rotating rod 15.

[0049] When the power motor 16 is started, the rotating shaft 17 drives the rotating rod 15 to rotate.

[0050] The working principle and use process of this utility model:

[0051] First, the operator places the pipe to be processed on the top of the first fixed mold 8, and then starts the pneumatic cylinder 10 to move the second fixed mold 11 downward, thereby clamping and fixing the pipe to be processed. Then the operator starts the power motor 16 to rotate the rotating shaft 17 through the rotating rod 15 with one end of the connecting rod 14, so that the other end of the connecting rod 14 generates a pulling force on the slider 13, pulling the slider 13 and moving the stopper 12 along the inner surface of the operating table 2 until the outer surface of the stopper 12 contacts the pipe to be processed, thereby supporting it. With the mutual cooperation of various mechanisms, support for pipes of different lengths is achieved.

[0052] Then the operator starts the driving motor 501, causing the double-threaded rod 502 to rotate. At this time, the two movable blocks 503 threadedly connected to the double-threaded rod 502 will carry one end of the connecting plate 406 to move toward each other along the outer surface of the limit rod 504, so that the other end of the connecting plate 406 generates a thrust on the bottom plate 403, pushing the bottom plate 403 to move upward along the outer surface of the limit plate 401 with the fixed plate 404 and the hydraulic cylinder 405 until the reaming die 7 is aligned with the pipe to be processed. Then the operator can start the hydraulic cylinder 405, thereby pushing the rectangular plate 6 to move the reaming die 7 toward the pipe to be processed, thereby completing the reaming operation, thereby realizing the height adjustment of the hydraulic cylinder 405 and the reaming die 7, so that after the reaming die 7 is replaced, the tube expander does not need to replace the first fixed die 8 and the second fixed die 11, thereby facilitating the alignment with the pipe to be processed after the die is replaced, thereby improving the convenience of using the tube expander.
