[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1

[0032] Reference Figure 1-7 The present embodiment provides a pipe clamping mechanism and a pipe bending machine, including a supporting assembly 100, including a fixing member 101, the fixing member 101 is connected to a movable member 102, and a chuck 103 is provided at the connection between the fixing member 101 and the movable member 102; a fixing assembly 200, including a clamping block 201 arranged on the fixing member 101, and an adjusting member 202 is inserted into the clamping block 201.

[0033] Specifically, after the fixed member 101 is connected to the movable member 102 , there is a certain angle between the two, which can ensure that when a thrust is applied to the movable member 102 , the movable member 102 can rotate around the center of the chuck 103 .

[0034] Preferably, the clamping block 201 is installed on the fixing member 101 through the adjusting member 2021. When the diameter of the straight pipe to be clamped is too large, the installation position of the clamping block 201 can be changed at will by simply taking out the adjusting member 202 along the notch on the fixing member 101.

[0035] Furthermore, the movable member 102 is clamped in the fixed member 101 , so the diameter of the straight tube needs to be smaller than the height of the movable member 102 , otherwise the straight tube cannot be fixed.

[0036] In actual use, the position of the clamping block 201 is first determined according to the diameter of the straight tube, and then the straight tube is passed through the fixed part 101 and the second fixed part 102b on the movable part 102, and then the straight tube is fixed by the chuck 103 and the clamping block 201, and the movable part 102 is pushed under the action of external force. Since the second fixed part 102b is fixedly arranged on the movable part 102, when the movable part 102 rotates under the action of external force, it will drive the second fixed part 102b to rotate synchronously, so the straight tube fixed in the second fixed part 102b is bent as it rotates.

[0037] By setting up the device, not only can the straight pipe be reliably clamped and quickly bent, but it can also be used to bend straight pipes with different diameters, with a wide range of applications and a fast installation speed.

[0038] Example 2

[0039] Reference Figure 2-5, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the fixing member 101 includes two symmetrically arranged fixing rods 101a, the two fixing rods 101a are fixed by bolts 104, a plurality of limiting grooves 101b are evenly opened on the fixing rod 101a, and a fixing groove 101c is arranged on the inner wall of the limiting groove 101b; the movable member 102 includes two symmetrically arranged movable rods 102a, the two movable rods 102a are fixed by bolts 104, a second fixing member 102b is fixedly connected to the movable rod 102a, and a pointer 102b-1 is arranged on the second fixing member 102b; a rotating shaft 103a is arranged at the center of the chuck 103, the rotating shaft 103a is connected to the fixing member 101 and the movable member 102 at the same time, and a plurality of positioning holes are distributed on the circumference of the chuck 103 103b, a scale plate 103c is provided at the bottom of the chuck 103; a semicircular groove 201a is provided on the side wall of the clamping block 201, slots 201b are provided on the upper and lower surfaces of the clamping block 201, and a ratchet groove 201c is provided at the bottom of the slot 201b; the adjusting member 202 comprises a knob 202a and a rod body 202b, a fixing strip 202a-1 is provided at the bottom of the knob 202a, a moving ring 202b-1 is movably sleeved on the rod body 202b, a fixing ring 202b-2 is provided at the bottom of the rod body 202b, an adjusting spring 202b-3 is provided between the moving ring 202b-1 and the fixing ring 202b-2, an adjusting wheel 202c is provided at the bottom of the rod body 202b, a plurality of ratchets 202c-1 are provided on the circumference of the adjusting wheel 202c, and a spring 202c-2 is provided between the ratchet 202c-1 and the adjusting wheel 202c.

[0040] Specifically, since the opening of the clamping block 201 faces the direction opposite to the direction in which the movable rod 102 rotates during bending, when the straight tube is bent, the fixing assembly 200 will only be subjected to a force in the direction away from the opening of the limiting groove 101b. Therefore, even if the adjusting member 202 is not fixed, the fixing assembly 200 will not fall off the fixing member 101. Through the opening of the limiting groove 101b, when adjusting the installation position of the clamping block 201, it is only necessary to directly take it out. When installing the clamping block 201, it is only necessary to insert the adjusting member 102 into the limiting groove 101b and embed the fixing strip 202a-1 into the fixing groove 101c, which saves the time required for disassembly and assembly and greatly improves work efficiency.

[0041] Preferably, when the straight tube is bent, the pointer 102b-1 can point to the corresponding scale on the dial 103c. Through the cooperation between the pointer 102b-1 and the dial 103c, the degree of bending of the straight tube can be known at any time, thereby improving the accuracy of the bending. If the bending angles of all bent tubes need to be consistent, a limit rod can be inserted into the corresponding positioning hole 103b to limit the rotation angle of the movable rod 102, thereby ensuring that the bending angles of the straight tubes are consistent.

[0042] Furthermore, the directions of the ratchet grooves 201c on the upper and lower surfaces of the clamping block 201 are opposite to each other. When the adjusting member 202 is inserted into both surfaces, it can be ensured that the clamping block 201 will not rotate.

[0043] In this embodiment, the installation position of the clamping block 201 is first determined according to the diameter of the straight tube, and then the straight tube is fixed in the semicircular groove 201a of the clamping block 201 and passes through the second fixing piece 102b. Generally, the gap between the clamping block 201 and the chuck 103 is not consistent with the diameter of the straight tube, and the straight tube is prone to shaking, which will affect the accuracy of subsequent bending and even pose a safety hazard. Therefore, after the straight tube is initially fixed, some adjustments need to be made to the clamping block 201 to ensure the stability of the straight tube.

[0044] In order to keep the straight tube fixed, it is necessary to ensure that the semicircular groove 201a of the clamping block 201 is close to the outer wall of the straight tube. At this time, you only need to pull the adjusting piece 202 on one side outward to make the adjusting wheel 202c disengage from the ratchet groove 201c. Since the movable ring 202b-1 is movably sleeved on the rod body 202b, the adjusting spring 202b-3 will be compressed while pulling the adjusting piece 202. In this case, the clamping block 201 is only restricted by the other adjusting piece 202 and can rotate in one direction. Through the rotation of the clamping block 201, the semicircular groove 201a is tightly pressed against the surface of the straight tube to prevent the straight tube from shaking. After the adjustment is completed, the pulled-out adjusting piece 202 is released. Under the action of the restoring force of the adjusting spring 202b-3, the adjusting wheel 202c is re-embedded in the ratchet groove 201c, and the clamping block 201 is fixed in both directions to prevent rotation during the bending process.

[0045] By providing the fixing assembly 100 , a straight pipe of any diameter can be clamped, and the stability of the clamping and the accuracy of the bending can be ensured.

[0046] Example 3

[0047] Reference Figure 6-7 , which is the third embodiment of the utility model, and this embodiment provides a pipe bending machine. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a bending component 300 includes a support frame 301, a cylinder 302 is provided on the support frame 301, and a positioning column 303 is provided on the top of the support frame 301; a universal wheel 301a is provided at the bottom of the support frame 301, and a storage table 301b is provided on the support frame 301; the cylinder 302 is fixed on the storage table 301b, and two air pipes 302a are provided on the cylinder 302; the positioning column 303 is fixedly connected to the fixing member 101, and a driving member 304 is provided on one side of the positioning column 303, and the driving member 304 includes a shell 304a and a push rod 304b, the shell 304a is provided with an air inlet 304a-1 and an air outlet 304a-2, and the push rod 304b is connected to the movable member 101.

[0048] Specifically, the universal wheels 301a at the bottom of the support frame 301 facilitate the transportation of the device, thereby reducing a large amount of labor costs.

[0049] Preferably, when the positioning column 303 is connected to the fixing member 101, the angle between the two is an obtuse angle, and they are not in the same straight line. The driving member 304 is horizontally fixed on one side of the positioning column 303, so the movable member 102 and the push rod 304b are also not in the same straight line. Therefore, the thrust applied by the push rod 304b to the movable member 102 cannot be in the direction of the movable member 101, thereby avoiding the movable member 102 from being squeezed and damaged.

[0050] In this embodiment, the gas is outputted through the cylinder 302, and the outputted gas is passed into the gas connection pipe 302a connected to the gas inlet 304a-1. Since the driving member 304 is sealed, after the gas is passed into the driving member 304, the internal gas pressure increases, and the push rod 304b is pushed outward. When the push rod 304b moves outward, it will drive the movable rod 102 to rotate, thereby completing the bending of the straight tube. After the bending of the straight tube is completed, the cylinder 302 again passes gas into the gas connection pipe 302a connected to the gas outlet 304a-2, and pushes the push rod 304b back again.

[0051] By providing the bending assembly 300, the power required for bending the straight pipe can be provided, reducing the operation of bending the straight pipe by manpower, thereby improving the bending efficiency while reducing the labor cost.
