[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0024] This utility model provides a pipe bending machine for bending pipes 6, comprising: a fixed base 1 with a fixed disc 101 detachably mounted on the top; a rotating handle 2 rotatably connected to the fixed base 1, with multiple mounting positions preset on the rotating handle 2; and a movable base 3 detachably mounted on one mounting position of the rotating handle 2, with a movable disc 301 detachably mounted on the top. The fixed disc 101 and the movable disc 301 cooperate to bend the pipe 6.
[0025] In practice, the rotating handle 2 is rotatably mounted on the fixed base 1. Multiple mounting positions are preset on the rotating handle 2. The movable disc 301 is mounted on one of the mounting positions for the pipe 6 to be bent as needed. The fixed disc 101 is mounted on the fixed base 1. The pipe 6 is placed between the fixed disc 101 and the movable disc 301. The rotating handle 2 is then turned, causing the movable disc 301 on the movable base 3 to rotate. The pipe 6 is bent between the fixed disc 101 and the movable disc 301. First, the fixed disc 101 and the movable disc 301 are detachably mounted on the fixed base 1 and the movable base 3, respectively. The detachable mounting facilitates the replacement of the fixed disc 101 and the movable disc 301. The fixed disc 101 and the movable disc 301 can be replaced to fit different sizes of pipes 6. Second, the movable base 3 is detachably mounted on the mounting position and rotates with the rotating handle 2. The movable base 3 can be mounted on different mounting positions to accommodate different sizes of pipes 6.
[0026] Furthermore, the fixed disc 101 is a stationary pressure plate mounted on the fixed base 1, and the movable disc 301 is a disc that moves with the movable base 3. Grooves are provided around the edges of both the fixed and movable discs 101 and 301. A pipe 6 is placed between the fixed and movable discs 101, located within the grooves of both the fixed and movable discs 301. These grooves limit the movement of the pipe 6, ensuring its stability during bending. The fixed base 1 has screw holes through which the fixed disc 101 is detachably fixed. The rotating handle 2 has an elongated hole through which the movable base 3 is fixed to its mounting position by bolts passing through the elongated hole. Each different hole on the elongated hole is a mounting position. The movable seat 3 can be installed in different positions on the elongated hole. The movable seat 3 has a through hole. The screw is passed through the elongated hole and the through hole on the movable seat 3 in sequence, and the movable seat 3 is fixed with the nut. The movable seat 3 has a positioning pin 302. The movable disc 301 has a through hole. The positioning pin 302 is passed through the through hole on the movable disc 301 so that the movable disc 301 is detachably positioned on the movable seat 3. The fixed seat 1 has a circular structure. One end of the rotating handle 2 is ring-shaped. The ring-shaped end of the rotating handle 2 is sleeved on the fixed seat 1 so that the rotating handle 2 can rotate around the fixed seat 1. The elongated hole is set on the handle of the rotating handle 2.
[0027] In some embodiments, a base 4 is also included, and a fixing seat 1 is mounted on the base 4.
[0028] During implementation, the fixing seat 1 is installed on the base 4, and the base 4 serves to fix and support the base 4.
[0029] In some embodiments, the base 4 is provided with a tube limiting member 5, which is located on one side of the rotating handle 2 and is used to abut one end of the tube 6.
[0030] During implementation, a pipe limiting component 5 is installed on the base 4. The pipe limiting component 5 is installed on one side of the rotating handle 2. After the pipe 6 is placed between the moving disc 301 and the fixed disc 101, the pipe limiting component 5 abuts against one end of the hanger, so that one end of the pipe 6 remains stationary. The other end of the pipe 6 is rotated and bent when the rotating handle 2 is turned.
[0031] In some embodiments, the pipe fitting limiting member 5 includes an adjusting block 501 and a limiting block 502. The limiting block 502 is detachably mounted on the adjusting block 501. The base 4 has multiple through holes and an elongated hole. The adjusting block 501 is connected to the base 4 by bolts passing through the through holes and the elongated hole. The adjusting block 501 is used to adjust the position of the limiting block 502, and the limiting block 502 is used to abut one end of the pipe fitting 6.
[0032] In practice, the strip on the adjusting block 501 is aligned with the through hole on the base 4. The bolt is passed through the through hole on the base 4 and the strip hole on the adjusting block 501. Finally, the adjusting block 501 is fixed to the base 4 by using a nut and bolt. The limiting block 502 is detachably fixed to the adjusting block 501. The limiting block 502 is used to limit one end of the pipe 6. When different pipes 6 are bent, one end of the pipe 6 will be in different positions. Therefore, the strip on the adjusting block 501 can be aligned with the through hole at different positions on the base 4 to fix it, thereby changing the position of the adjusting block 501. The limiting block 502 on the adjusting block 501 will also change position with the adjusting block 501, so that the limiting block 502 can abut against the pipes 6 at different positions.
[0033] Furthermore, the limiting block 502 abuts against the tube body at one end of the tube 6.
[0034] In some embodiments, the adjusting block 501 is provided with multiple through holes, and the limiting block 502 is provided with an elongated hole. The limiting block 502 is detachably connected to the adjusting block 501 by bolts passing through the through holes on the base 4 and the elongated hole on the limiting block 502 in sequence.
[0035] During implementation, the elongated hole on the limiting block 502 is aligned with the through hole on the adjusting block 501. The limiting block 502 is detachably connected to the adjusting block 501 by bolts passing through the through hole on the base 4 and the elongated hole on the limiting block 502 in sequence. This installation method allows the limiting block 502 to change its installation position on the adjusting block, thereby further increasing the adjustable space of the limiting block 502 and adapting to limiting more different champions.
[0036] In some embodiments, the adjustment block 501 is provided with a support column 503, and the support column 503 is provided with a limiting plate 504, which is detachably connected to the support column 503.
[0037] During implementation, a support column 503 is installed on the adjustment block 501, and a limiting plate 504 is installed on the support column 503. The limiting plate 504 is used to abut the end of the pipe 6. The limiting block 502 in the pipe limiting component 5 is used to limit the pipe body at one end of the pipe 6, and the limiting plate 504 is used to limit the end of the pipe 6. The limiting block 502 prevents the pipe 6 from shifting laterally, and the limiting plate 504 prevents the pipe 6 from shifting longitudinally, ensuring the stability of the pipe 6 so that one end is not bent.
[0038] Since different pipes 6 may have different lengths, in some embodiments, the limiting plate 504 is provided with a through hole, and the support column 503 passes through the through hole on the limiting plate 504.
[0039] During implementation, the support column 503 is passed through the through hole on the limiting plate 504. The limiting plate 504 can be fixed at any position on the support column 503. The position of the limiting plate 504 is adjusted according to the different positions of one end of the pipe 6, so that the limiting plate 504 can adapt to pipes 6 of different lengths.
[0040] Furthermore, the support column 503 is provided with external threads, and the limiting plate 504 is fixed by nuts on both sides.
[0041] In some embodiments, the base 4 is provided with an annular hole 401, and a limiting post (not shown in the figure) is provided in the annular hole 401, which surrounds the fixed base 1. The limiting post is used to limit the rotation handle 2.
[0042] During implementation, a limiting post is installed in the predetermined position of the annular hole 401 according to the angle that the pipe 6 needs to be bent. After the rotating handle 2 is turned and the pipe 6 is bent to the predetermined angle, the rotating handle 2 will be resisted by the limiting post, so that the rotating handle 2 can no longer rotate, thereby ensuring the accuracy of the bending angle.
[0043] The limiting post is a screw that passes through the annular hole 401 from the bottom of the base 4 and is then fixed by a nut. The bottom of the annular hole 401 is provided with a step, which is used to accommodate the screw nut and keep the bottom of the base 4 flat.
[0044] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
