Abstract

This utility model discloses an integrated pipe bending and chamfering machine, relating to the field of pipe bending technology. It includes a base and a chamfering device. Two sets of crossbars are fixedly installed on the top of the base, and a first electric cylinder is fixedly installed on one side of the top of the base. In this utility model, the rotating base is rotated 90° counterclockwise via a rotary support shaft. Then, the first electric cylinder is activated, causing it to push a moving trolley to move to the right on the crossbars. The pipe body then fits tightly against the inner side of the second fixed block and the pipe bending wheel axle. A second electric cylinder is then activated by a operator, pushing the first fixed block so that one end of the first fixed block fits tightly against the outer side of the pipe body. The rotating base is then rotated clockwise via the rotary support shaft to the desired bending angle. During the bending process, the chamfering device can chamfer both ends of the pipe body, allowing bending and chamfering to be performed simultaneously without the need for manual handling, thus accelerating the pipe bending production efficiency.

[0002] Pipe bending machines are machines used for bending pipes and can also be used as jacks. They are generally divided into CNC pipe bending machines and hydraulic pipe bending machines, and are used in pipeline laying and repair in power construction, railway and highway construction, bridges, ships and other fields.

[0003] When our company processes pipe bends, the pipes must first be bent, and then manually transported to the chamfering equipment for reinstallation and chamfering of both ends. This process of bending and chamfering requires a lot of time for transportation and reinstallation, resulting in low production capacity and being time-consuming and labor-intensive. Utility Model Content

A left baffle and a right baffle are fixedly installed on the bottom edge of the lifting cylinder. A motor is installed at the bottom of the lifting cylinder, and the output end of the motor is connected to the top center of one set of gears in the gear set. A rotating shaft is installed at the center of another set of gears in the gear set, and one end of the rotating shaft is inserted into the interior of the left baffle.

The tube body can then be tightly attached to the inner side of the second fixed block and the bending wheel axle. Then, the operator activates the second electric cylinder, which pushes the first fixed block so that one end of the first fixed block is tightly attached to the outer side of the tube body. The rotating base is then rotated clockwise via the rotary support shaft to the required bending angle.

[0024] The chamfering device 5 includes a guide rail 51, a lifting cylinder 52, a motor 53, a left baffle 54, a right baffle 55, a gear set 56, a rotating shaft 57, a transmission belt 58, a connecting shaft 59, a chamfering cutter 510, a support frame 511, and a hollow turntable 512.

[0025] The guide rail 51 is located at the bottom of the support frame 511, and the support end of the guide rail 51 is fixedly connected to the lifting cylinder 52. The bottom edge of the lifting cylinder 52 is fixedly installed with a left baffle 54 and a right baffle 55 respectively. The bottom of the lifting cylinder 52 is equipped with a motor 53, and the output end of the motor 53 is connected to the top center of one set of gears in the gear set 56. The center of the other set of gears in the gear set 56 is equipped with a rotating shaft 57, and one end of the rotating shaft 57 is inserted into the interior of the left baffle 54. The rotating shaft 57 forms a belt drive with the connecting shaft 59 through the transmission belt 58. Both ends of the connecting shaft 59 pass through the hollow turntable 512 and two sets of chamfering cutters 510 are fixedly installed at the end.

[0026] Furthermore, gear set 56 consists of helical bevel gears arranged vertically.

[0027] Furthermore, the outer side of the connecting shaft 59 is fixedly connected to the inner side of the hollow turntable 512, and the two sets of hollow turntables 512 are fixedly installed inside the left baffle 54.

[0031] Working principle: In use, the tube body 12 is held by the pneumatic three-jaw chuck 4. After the holding is stable, the lifting cylinder 52 is moved above the end of the tube body 12 via the guide rail 51. Then, the lifting cylinder 52 is raised and lowered so that the chamfering cutter 510 is aligned with the tube body 12. The motor 53 is started, which drives the gear set 56 to rotate. The vertically set helical bevel gear drives the rotating shaft 57 to rotate. At the same time, the rotating shaft 57 drives the connecting shaft 59 to rotate via the transmission belt 58. The chamfering cutters 510 at both ends of the connecting shaft 59 will rotate. At this time, the chamfering cutter 510 is driven to move to the left via the guide rail 51. The left chamfering cutter 510 can chamfer one end of the tube body 12. After the chamfering is completed, the chamfering device 5 returns to its original position. At the same time, the rotating base 7 is rotated 90° counterclockwise via the rotary support shaft 6. Then, the first electric cylinder 13 is started so that the first Electric cylinder 13 pushes the moving trolley 3 to move to the right on the crossbar 2, so that the tube body 12 can be tightly attached to the inner side of the second fixed block 11 and the bending wheel axle 9. Then, the operator starts the second electric cylinder 16, which pushes the first fixed block 8 so that one end of the first fixed block 8 is tightly attached to the outer side of the tube body 12. Then, the rotating base 7 is rotated clockwise through the rotary support shaft 6 to the required bending angle. While bending the tube, the tube body 12 will move slightly to the right, and the lead screw guide rail 15 will drive the second fixed block 11 to move together, so that the second fixed block 11 and the first fixed block 8 fix the tube body 12 to the outer side of the bending wheel axle 9. Then, the operator starts the chamfering device 5 as described above, and chamfers the other end of the tube body 12 with the chamfering cutter 510 on the right end. After the chamfering is completed, the rotating base 7 is rotated to pull out the tube body 12, thus completing the bending and chamfering at the same time.
