When this novel high-efficient hydraulic pipe bender of needs uses, its theory of operation as follows:

the preparation process comprises the following steps:

firstly, the circular tube 16 can be conveyed from the right side to the left side of the whole device through an external conveying structure, the circular tube 16 can firstly cling to the right end of the stop block 201, the inner walls of the fixed clamping plate 205 and the fixed roller 15 sequentially penetrate through the circular tube 16 and finally abut against the right end of the stop block 201, then the conveying of the circular tube 16 is stopped, meanwhile, the driving air cylinder 10 at a processing station (namely the front end position) enables the driving air rod 17 inside to extend outwards, the driving air rod 17 enables the movable roller 8 to drive the movable roller 8 to rotate forwards by 90 degrees around the pin shaft 21 through the base 13 and the support rod 9, the inner arc-shaped groove of the movable roller 8 is pressed on the outer wall of the other side of the circular tube 16, the inner arc-shaped grooves of the movable roller 8 and the fixed roller 15 completely wrap the outer wall of the circular tube 16, meanwhile, the clamping air cylinder 203 controls the clamping air rod 207 to extend out, the movable clamping plate 204 is driven to press on the surface of the fixed clamping plate 205, the movable clamping plate 204 and the outer wall of the circular tube 16 are clamped to be fixed, finally, the stop air rod 206 is controlled by the stop air cylinder 202 to retract, the air blocking rod 206 drives the stop block 201 to retract backwards, so as to make room for the bent pipe of the circular pipe 16.

A pipe bending process:

after the preparation process before bending the pipe is finished, a user can start the driving motor 301, so that the output shaft of the driving motor 301 drives the driving shaft 306 to rotate through the speed reducer 302, meanwhile, the driving shaft 306 can drive the driven shaft 305 to rotate through the driving gear 303 and the driven gear 304, finally, the driven shaft 305 can drive the rotating platform 11 to rotate, so that the rotating platform 11 can drive the movable roller 8 to rotate 90 degrees through the support plate 12, the movable roller 8 rotates 90 degrees on the outer wall of the fixed roller 15, so that the originally straight circular pipe 16 can only be bent along the rotating radian of the movable roller 8 to realize the pipe bending processing, because the movable roller 8 and the fixed roller 15 form a pipe bending structure in a rotating mode, compared with the traditional movable roller 8 telescoping mode and the fixed roller 15, the movable roller 8 and the fixed roller 15 are attached to the circular pipe 16 in a buckling and opening process faster in the rotating mode in the scheme, the efficiency is higher.

A limiting process:

in the preparation process of the bent pipe, the support plate 12 is controlled by the driving cylinder 10 to rotate forwards, the arc of the outer wall at the tail end of the clamping block 403 is attached to the chamfer inclined planes at the upper side and the lower side of the outer wall of the fixed roller 15 in the rotation process of the support plate 12, so that the clamping block 403 can be blocked and driven to retract towards the inside of the support plate 12 to extrude the spring 405, and after the support plate 12 rotates for 90 degrees, the clamping block 403 is popped up by the elastic force of the spring 405 and inserted into the clamping groove 401, so that after the movable roller 8 and the fixed roller 15 are buckled on the circular pipe 16, the clamping block 403 and the clamping groove 401 can form clamping connection, therefore, the movable roller 8 cannot rotate reversely to open, so as to resist the reaction force of the circular pipe 16 on the movable roller 8 in the bent pipe, compared with the direct resistance of the cylinder to the reaction force in the traditional bent pipe, the scheme greatly reduces the reaction force applied to the driving cylinder 10 in the bent pipe bending process, thereby greatly prolonging the service life of the driving cylinder 10, the problem that the driving cylinder of the movable roller is easily damaged due to the fact that the movable roller is located at a large reaction force for a long time is solved, after the movable roller 8 rotates to 90 degrees, on one hand, the pipe bending of the circular pipe 16 is completed, meanwhile, the clamping block 403 rotating along with the support plate 12 also just rotates to the corresponding notch 406 to remove clamping, the movable roller 8 can be controlled to rotate reversely by the driving cylinder 10 after rotating by 90 degrees, and the clamping of the movable roller 8 and the fixed roller 15 to the circular pipe 16 is removed.

And (3) subsequent processes:

after the pipe bending is completed for one time, the clamping air rod 207 and the movable clamping plate 204 can be controlled by the clamping air cylinder 203 to retreat, a user can take out the circular pipe 16 after the pipe bending according to the requirement, or the circular pipe 16 is continuously pushed leftwards again by an external conveying structure, the circular pipe is stopped after being pushed for a certain distance, and the circular pipe 16 is clamped again by the control of the clamping air cylinder 203, in the process, because the rotating platform 11 rotates 90 degrees during the last pipe bending, the original processing station rotates to the idle station, and the idle station at the rightmost end rotates to the processing station, the pipe bending can be completed again by repeating the operation of the pipe bending process, after the pipe bending is completed by the continuous replacement of the station, the movable roller 8 can perform the pipe bending again without reversely rotating and resetting, the pipe bending 90 degrees are the positions which can be just replaced with each other between the stations, so that the time and the process of the rotating and the resetting are omitted, the processing efficiency in the pipe bending process is greatly improved.

And (3) adjusting:

because the angle difference of 90 degrees exists between the clamping block 403 and the notch 406 of the clamping groove 401, when the bending at other angles is required, the reverse opening process after the bending of the movable roller 8 is difficult, therefore, the scheme designs the adjusting component 5, so that the expansion and contraction of the adjusting air rod 503 can be controlled by the adjusting air cylinder 501 when needed, the adjusting air rod 503 can drive the gear 506 and the turntable 502 to rotate through the cross rod 504 and the rack 505, and the turntable 502 can drive the fixed roller 15 to rotate through the sleeve 20, because draw-in groove 401 and breach 406 are all processed in the upper end outside of fixed roll 15, consequently the rotation of fixed roll 15 can drive breach 406 and rotate, makes the angle between breach 406 and the fixture block 403 adjust, makes things convenient for movable roll 8 to open in the reversal after corresponding return bend angle, has avoided unable reduction to drive the specific return bend angle problem of adjusting movable roll when actuating cylinder reaction force.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
