DETAILED DESCRIPTION
[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0021] The utility model provides a bending and forming device for plastic pipe processing, such as Figure 1-3 As shown, it includes a workbench 1 and a control system 20, the control system is placed on the front end side of the workbench 1, two guide blocks 2 are arranged in the middle of one side of the workbench 1, the two guide blocks 2 are relatively spliced to form a semicircular groove structure for conveying plastic pipes, a pushing mechanism is arranged in the middle of one side edge of the workbench 1, and the pushing mechanism corresponds to the two guide blocks 2, the top surface of the workbench 1 is located at one end of the two guide blocks 2 and a heating coil 3 is embedded and installed, the top surface of the workbench 1 is located at one end of the heating coil 3 and a rotating shaft 4 is rotatably installed, and the rotating shaft 4 is arranged perpendicular to the workbench 1, the top surface of the workbench 1 is located in the circumferential direction of the rotating shaft 4 and an arc-shaped slide groove 5 is opened, the bottom of the arc-shaped slide groove 5 is slidably installed with a driving mechanism, the top surface of the driving mechanism is fixedly connected with a pipe pressing mechanism, and the pipe pressing mechanism is placed on the top surface of the workbench 1, and the top surface of the workbench 1 is located directly above the rotating shaft 4 and a cooling mechanism is arranged.
[0022] The plastic pipe is fed by the push mechanism in cooperation with the two guide blocks 2, and the bent part of the plastic pipe is heated and softened by the rotating shaft 4, so that the plastic pipe is more easily deformed, which not only reduces the possibility of plastic pipe rupture during bending, but also facilitates the bending work. Then, the plastic pipe is automatically bent by the pipe pressing mechanism and the driving mechanism in cooperation with the system, and finally, the bent plastic pipe is cooled and shaped by the added cooling mechanism, which greatly improves the automation degree of plastic pipe bending and provides convenience for the plastic pipe bending work.
[0023] The tube pressing mechanism is composed of a second cylinder 9 and a pressing block 10. The second cylinder 9 is installed on the top surface of the driving mechanism. The pressing block 10 is fixedly installed on the movable end of the second cylinder 9, and an arc-shaped groove matching the plastic tube is opened at the front end of the pressing block 10. When bending, the piston end of the second cylinder 9 drives the pressing block 10 to move forward and abut the plastic tube, and then the set driving mechanism is used to drive the second cylinder 9 and the pressing block 10 to move along the center point of the rotating shaft 4, and cooperate with the abutment of the rotating shaft 4 on the plastic tube to complete the bending of the plastic tube.
[0024] The driving mechanism is composed of a limit rod 11, a slider 12, a reduction motor 13, a gear 14 and an annular rack 15. The limit rod 11 is placed in the arc chute 5 and slides inside the arc chute 5. The slider 12 is fixedly mounted on the top surface of the limit rod 11 and slides on the top surface of the workbench 1. The reduction motor 13 is fixedly connected to the bottom of the limit rod 11. The gear 14 is fixedly mounted on the output shaft of the reduction motor 13. The annular rack 15 is fixedly mounted on the top surface of the workbench 1 and is placed on the outer edge of the arc chute 5 and is coaxially arranged with the arc chute 5. The gear 14 is meshed with the annular rack 15. When bending, the opening Start the reduction motor 13, which drives the gear 14 to rotate. Since the gear 14 is meshed with the annular tooth 15, the sliding connection between the arc-shaped slide groove 5 and the limit rod 11 and the slider 12 makes the second cylinder 9 and the pressing block 10 rotate along the outer circumferential direction of the rotating shaft 4. At the same time, the heated softening point of the plastic contacts the rotating shaft 4, and the tube pressing mechanism that cooperates with the pressing rotation performs the bending work. The required angle can be bent arbitrarily according to the control of the control system 20. There is no need to replace new equipment when bending plastic tubes of different angles, which greatly reduces the cost required for production equipment and improves the practicality of the bending equipment.
[0025] The cooling mechanism consists of a second bracket 16, a fan 17, a refrigeration system 18, a connecting pipe 19 and a control system 20. The second bracket 16 is fixedly mounted at the rear end of the rotating shaft 4, the fan 17 is fixedly mounted at the top front end of the second bracket 16 and is in a vertical correspondence with the rotating shaft 4, the refrigeration system 18 is fixedly mounted on the top surface of the workbench 1 at the rear end of the guide block 2, and the air outlet of the refrigeration system 18 is connected to the air inlet of the fan 17 through the connecting pipe 19. After bending, the fan 17 and the refrigeration system 18 are turned on, and the cold air generated by the refrigeration system 18 is sprayed to the heated and softened part of the plastic pipe through the fan 17, so that the heated and bent part of the plastic pipe is immediately cooled and shaped.
[0026] The pushing mechanism consists of a first bracket 6, a first cylinder 7 and a top block 8. The first bracket 6 is fixedly installed in the middle of one side edge of the workbench 1, the first cylinder 7 is fixedly installed at the top end of the first bracket 6, and the top block 8 is fixedly connected to the piston end of the first cylinder 7. When pushing, the plastic tube is placed on the two guide blocks 2. At this time, the first cylinder 7 is turned on, and the retractable piston end of the first cylinder 7 drives the top block 8 to move forward to push the plastic tube, so that the plastic tube moves forward into the heating ring 3 to heat and soften the bent part. The softened plastic tube continues to be pushed to the rotating shaft 4, and the driving mechanism and the tube pressing mechanism are cooperated to perform the bending process.
[0027] The arc chute 5 is a three-quarter annular structure, that is, the arc chute 5 is a 270° fan-shaped structure. One end of the arc chute 5 is located at the rear end of the rotating shaft 4, so that the pressing block 10 set by the driving mechanism just corresponds to the plastic pipe, and the other end extends to the heating ring 3, so that the plastic pipe can be bent into any angle between 0°-180°.
[0028] The control system 20 is electrically connected to the first cylinder 7, the second cylinder 9, the reduction motor 13, the fan 17 and the refrigeration system 18 respectively. The control system 20 is used to set and edit the operation and opening and closing of the first cylinder 7, the second cylinder 9, the reduction motor 13 and the fan 17.
[0029] The working principle of the utility model is as follows: a plastic tube is placed on two guide blocks 2, and the first cylinder 7 is turned on at this time. The telescopic piston end of the first cylinder 7 drives the top block 8 to move forward to push the plastic tube, so that the plastic tube moves forward into the heating ring 3 to heat and soften the bent part. After softening, the heating ring 3 is closed, and then the softened part of the plastic tube continues to be pushed to the rotating shaft 4. At this time, the piston end of the second cylinder 9 drives the pressing block 10 to move forward to abut the plastic tube, and then the reduction motor 13 drives the gear 14 to rotate. Since the gear 14 is meshed with the annular gear 15, the sliding connection between the matching arc-shaped slide groove 5 and the limit rod 11 and the slider 12 makes the second cylinder 9 and the pressing block 10 run along the outer circumferential direction of the rotating shaft 4. At the same time, the heated and softened point of the plastic contacts the rotating shaft 4, and the pressing block 10 rotates in cooperation with the pressing and fitting to perform the bending work. After bending, the fan 17 and the refrigeration system 18 are turned on, and the cold air generated by the refrigeration system 18 is sprayed to the heated and softened part of the plastic tube through the fan 17, so that the heated and bent part of the plastic tube is immediately cooled and shaped.
