When this high-efficiency hydraulic pipe bender is needed, its working principle is as follows:

Preparation process:

Firstly, the round tube 16 can be conveyed from the right side to the left side of the overall device through the external conveying structure. The round tube 16 can pass through the inner wall of the fixed splint 205 and the fixed roller 15 in sequence and finally abut against the right end of the stopper 201, and then Stop the conveyance of the round tube 16, and the drive cylinder 10 at the processing station (i.e. the front end position) at the same time makes the internal drive air rod 17 stretch out, so that the drive air rod 17 drives the movable roller 8 through the base 13 and the strut 9 Turn forward 90° around the pin shaft 21, so that the inner arc groove of the movable roller 8 is pressed against the outer wall of the other side of the round pipe 16, so that the inner arc groove of the movable roller 8 and the fixed roller 15 completely wraps the inner arc groove of the round pipe 16. At the same time, the clamping cylinder 203 controls the clamping air rod 207 to stretch out, driving the movable splint 204 to press on the surface of the fixed splint 205, so that the movable splint 204 and the fixed splint 205 are clamped on the outer wall of the round tube 16 to fix it, and finally the material is blocked The cylinder 202 controls the retraction of the stopper gas rod 206, so that the stopper 201 is retracted backward by the stopper gas rod 206, so as to make room for the bend of the round pipe 16.

Bending process:

After completing the preparation process before bending the pipe, the 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 reducer 302, and the driving shaft 306 can be driven by the driving gear 303 and the driven gear 304 The driven shaft 305 rotates, and 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 by 90° through the support plate 12, and the movable roller 8 rotates through 90° on the outer wall of the fixed roller 15 °, so that the originally straight round pipe 16 can only be bent along the rotation arc of the movable roller 8 to realize the pipe bending process. Since the movable roller 8 is used to rotate and the fixed roller 15 to form a curved pipe structure, compared with the traditional movable The telescopic mode of the roller 8 fits with the fixed roller 15. In this scheme, the movable roller 8 rotates to make the process of engaging and opening the movable roller 8 and the fixed roller 15 to the round pipe 16 faster and more efficient.

Limit process:

During the preparation process of the pipe bend, since the support plate 12 is rotated forward under the control of the driven cylinder 10, the outer wall arc at the end of the block 403 will stick to the chamfered slopes on the upper and lower sides of the outer wall of the fixed roller 15 during the rotation of the support plate 12. close, so that the block 403 can be blocked and driven to retract to the inside of the support plate 12, squeeze the spring 405, and after the support plate 12 rotates 90°, the block 403 is ejected by the elastic force of the spring 405, and inserted into the inside of the slot 401 After the movable roller 8 and the fixed roller 15 are fastened to the round pipe 16, the block 403 and the groove 401 can form a clamping connection, so the movable roller 8 will not be able to reversely rotate and open, so as to resist the round pipe when the pipe is bent. Compared with the reaction force of the pipe 16 on the movable roller 8, compared with the direct reaction force of the cylinder when the traditional pipe is bent, this solution greatly reduces the reaction force applied to the driving cylinder 10 during the pipe bending process, so it can greatly improve The service life of the driving cylinder 10 avoids the problem that the driving cylinder of the movable roller is easily damaged due to the large reaction force for a long time. After the movable roller 8 rotates to 90°, the bending process of the round pipe 16 is completed on the one hand, and at the same time The block 403 that rotates with the support plate 12 also just rotates to the corresponding notch 406 to release the clamping, so that the movable roller 8 can be reversed by the driving cylinder 10 again after rotating 90°, and the movable roller 8 and the fixed roller 15 are released. Fastening of the round pipe 16.

Subsequent process:

After a pipe bending is completed, the clamping cylinder 203 can control the clamping air rod 207 and the movable splint 204 to retreat, and the user can take out the round pipe 16 after the pipe bending according to the demand, or continue to move the round pipe 16 to the left again through the external conveying structure Push, stop after pushing a certain distance, and clamp the round pipe 16 again through the control of the clamping cylinder 203, and in this process, because the rotating platform 11 rotated 90 ° during the last pipe bending, the original processing work The station turns to the idle station, and the idle station at the far right turns to the processing station, so the bending process can be completed again by repeating the operation of the above bending process. After the bending is completed through the continuous replacement of the stations, the movable roller 8. It is not necessary to reverse the rotation and reset to perform the bending process again. The 90° bending tube can just replace the position between the stations, so as to omit the time and process of its rotation and reset, which greatly improves the processing in the bending process. efficiency.

Adjustment process:

Since there is an angle difference of 90° between the clamping block 403 and the notch 406 of the clamping groove 401, if it is necessary to bend the pipe at other angles, the reverse opening process after the movable roller 8 bends the pipe is relatively difficult, so this scheme is designed Adjustment assembly 5, can control and adjust the expansion and contraction of air rod 503 by adjusting cylinder 501 when needed, and then adjust air rod 503 and can drive gear 506 and rotating disk 502 to rotate through cross bar 504 and rack 505, and rotating disk 502 can be rotated simultaneously The fixed roller 15 is driven to rotate through the sleeve 20. Since the slot 401 and the notch 406 are all processed on the outer side of the upper end of the fixed roller 15, the rotation of the fixed roller 15 can drive the notch 406 to rotate, so that the notch 406 and the block 403 The angle between them can be adjusted, so that the movable roller 8 can be reversely opened after corresponding to the bending angle, avoiding the problem that the specific bending angle of the movable roller cannot be adjusted while reducing the reaction force of the driving cylinder.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
