It is roughly divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. It is used in power construction, road and railway construction, bridges, ships and other aspects of pipeline laying and repair. Pipe bending machine can be roughly divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. It is mainly used for power construction, railway construction, pipeline laying and repair of boilers, bridges, ships, furniture, decoration, etc. It has the advantages of multiple functions, reasonable structure and simple operation.

[0003] During the operation of the pipe bending machine, some small pipes need to be straightened in advance to ensure the stability of the subsequent processing and bending.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a straightening mechanism for a pipe bending machine, comprising a base 1 and an air guide hose 23, two first plates 2 are fixedly installed on the top of the base 1, two slide columns 4 are fixedly installed on the opposite sides of the two first plates 2, three slide seats 3 are slidably sleeved on the outer sides of the two slide columns 4, a plurality of fixing holes 5 are provided on the outer sides of the two slide columns 4, two second plates 11 are fixedly installed on the tops of the three slide seats 3, two slide rods 13 are fixedly installed on the opposite sides of the two second plates 11, springs 12 are sleeved on the outer sides of the two slide rods 13, two moving seats 14 are sleeved on the outer sides of the two slide rods 13, straightening rollers 15 are movably installed on the tops of the two moving seats 14 through bearing support seats, and three limiting arc grooves 1 are provided on the outer sides of the straightening rollers 15. 6. A support rod 22 is fixedly installed on the top of the straightening roller 15, and an air guide cover 17 is movably installed on the top of the support rod 22 through a bearing support seat, and an air guide cone 18 is fixedly installed on the top of the air guide cover 17, and a threaded mounting tube 19 is fixedly installed on the top of the air guide cone 18. A pillar 20 is fixedly installed at the center of the top of the straightening roller 15, and a plurality of turbine blades 21 are fixedly installed on the outer side of the pillar 20. Three mounting plates 8 are fixedly installed on the top of the base 1 by bolts, and gas elastic telescopic columns 9 are fixedly installed on the top of the three mounting plates 8, and an auxiliary frame 10 is fixedly installed on the top of the gas elastic telescopic column 9. A support 6 is fixedly installed on the top of the base 1, and three conical positioning holes 7 are opened inside the support 6. Two threaded mounting heads 24 are fixedly installed on the bottom end of the air guide hose 23.

[0020] The working principle of the above technical solution is as follows: when in use, the user arranges the pipeline for preliminary support, passes through the conical positioning hole 7, and passes through the auxiliary frame 10. The elastic support of the auxiliary frame 10 and the gas elastic telescopic column 9 supports the pipeline, and then the pipeline passes through the inner side of the straightening roller 15 and the limiting arc groove 16 to stabilize the position. At the same time, the threaded mounting head 24 is installed on the outer side of the threaded mounting tube 19, and the air guide hose 23 is connected to the air flow output device. After the air flow is output, it is introduced into the air guide cone 18 through the air guide hose 23 and the threaded mounting tube 19. The air guide cone 18 applies the air flow to the pillar 20 and the turbine blade 21. At this time, the turbine blade 21 is blown by the air flow and drives the pillar 20 and the straightening roller 15 to rotate. Due to the symmetrical distribution of the turbine blade 21, the rotation direction of the straightening roller 15 is opposite, so that the straightening roller 15 and the limiting arc groove 16 clamp the pipeline for transmission and perform straightening work, which stabilizes the operation and can cope with the straightening of small pipelines, and can adapt to different sizes of small pipelines for transmission operations, thereby improving efficiency.

[0021] In another embodiment, Figure 1-Figure 3 As shown, the fixing holes 5 are linearly and evenly distributed on the outside of the sliding column 4 , and the fixing holes 5 are also distributed on both ends of the sliding seat 3 . The sliding seat 3 is fixed to the relative position of the sliding column 4 by inserting bolts into the fixing holes 5 .

[0022] The setting of the fixing hole 5 can insert a bolt to fix the slide seat 3 at the required position of the slide column 4, which is convenient for adjusting the working position according to different pipelines, increases adaptability, and has a good overall use effect.

[0023] In another embodiment, Figure 1-Figure 3 As shown, one end of the spring 12 is fixedly mounted on one side of the second plate 11 , and the other end of the spring 12 is fixedly mounted on one side of the moving seat 14 .

[0024] The spring 12 is convenient for applying an elastic force to make the straightening roller 15 and the limiting arc groove 16 close to each other, so as to clamp the pipeline and stabilize the position of the pipeline to avoid falling, thereby increasing practicality.

[0025] In another embodiment, Figure 1-Figure 3 As shown, three limiting arc grooves 16 are linearly evenly distributed from top to bottom from small to large on the outside of the straightening roller 15, and rubber friction coating pads are arranged on the outside of the three limiting arc grooves 16. The three mounting plates 8 and the straightening roller 15 are evenly distributed in an alternating manner.

[0026] The size distribution of the limiting arc groove 16 facilitates the clamping of pipes of different sizes at the same time, so that large and small pipes can be clamped according to large and small holes, stabilizing the overall operation effect. The rubber friction coating pad facilitates the stable structure, increases the friction force, stabilizes the stability of pipe clamping, and reduces falling off.

[0027] In another embodiment, Figure 1-Figure 3 As shown, the turbine blades 21 are evenly distributed on the outer side of the support 20 in a circumferential manner, and the specifications and dimensions of the air guide cone 18 are adapted to the specifications and dimensions of the support 20 and the turbine blades 21 .

[0028] By setting the turbine blades 21 and the air guide cone 18, the air guide cone 18 blows the high-pressure airflow to the outside of the turbine blades 21 when the airflow is discharged. At this time, the turbine blades 21 are rotated by the high-pressure and high-speed airflow. The hose structure of the air guide hose 23 and the symmetrically distributed turbine blades 21 facilitate the adjustment of light plastic pipes and small steel pipes of different sizes by the limiting arc grooves 16 and the straightening rollers 15. When transmitting, the power does not need to be adjusted, which is convenient for power transmission, and changes the inconvenience of adjusting and transmitting power with the traditional mechanical rigid structure.

[0029] In another embodiment, Figure 1-Figure 4 As shown, the specifications and sizes of the two threaded mounting heads 24 are matched with the specifications and sizes of the threaded mounting tube 19 .

[0030] The threaded mounting head 24 and the threaded mounting tube 19 are installed by threaded connection, which facilitates the airflow of the air guide hose 23 to be directed to the threaded mounting tube 19, facilitates installation and use, and the overall structure is stable and convenient for operation.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
