[0022] like Figure 1-4 As shown, a copper tube bending machine for crystallizers includes: a base 1, a vertical stand 2, a support rod seat 3, a hinge seat 4, a first telescopic cylinder 9, and a second telescopic cylinder 15. The vertical stand 2 is fixedly connected to the top surface of the base 1. The first end of the support rod seat 3 is hinged to one side of the vertical stand 2. The output end of the first telescopic cylinder 9 is hinged to the second end of the support rod seat 3, and the first telescopic cylinder 9 is fixedly connected to the hinge seat 4. One end of the hinge seat 4 is hinged to the vertical stand 2. The second telescopic cylinder 15 is fixedly connected to the top of the vertical stand 2. The output end and the support rod 3 are both equipped with pressure roller structures, and the upright 2 is also equipped with a drive roller structure. The pressure roller structure includes the support rod 10 and the pressure roller 14, and the pressure roller 14 is rotatably connected to the support rod 10. The drive roller structure includes the transmission shaft 19, the motor 20, the connecting column 21 and the drive roller 24. The motor 20 is fixedly connected to the rear of the upright 2, the output shaft of the motor 20 is fixedly connected to the transmission shaft 19, and the drive roller 24 is fastened to the transmission shaft 19.
[0023] Specifically, the pressure roller 14 and drive roller 24 have grooves adapted to fit the copper tube to prevent the copper tube from falling off. The support 2 is a hollow structure. The support rod seat 3 is U-shaped, with its open end hinged to one side of the support 2 and its closed end hinged to the telescopic end of the first telescopic cylinder 9. The hinge seat 4 is U-shaped, with its open end hinged to the support 2. The first telescopic cylinder 9 is fixedly installed on the closed end of the hinge seat 4. The support rods 10 of the two sets of pressure roller structures are fixedly connected to the support rod seat 3 and the second telescopic cylinder 15, respectively, to prevent the support rods from falling off. The support rod 10 rotates, and simultaneously supports the rotation of the pressure roller 14, which in turn drives the pressure roller 14 to apply pressure to the copper pipe, causing it to bend. The drive shaft 19 is rotatably connected to the stand 2, and the drive roller 24 is fastened to the drive shaft 19. The motor 20 drives the drive shaft 19 to rotate, which in turn drives the drive roller 24 to rotate. The position of the drive roller 24 is fixed, which is used to provide power for conveying the copper pipe. While the pressure roller 14 applies pressure, the copper pipe is conveyed, causing the copper pipe to form an arc.
[0024] Furthermore, the first end of the support rod seat 3 is hinged to the upright seat 2 via the second rotating shaft 6, and the end of the hinge seat 4 is hinged to the upright seat 2 via the first rotating shaft 5. The first telescopic cylinder 9 is arranged at an angle, and its output end faces the second end of the support rod seat 3. The output end of the first telescopic cylinder 9 is fixedly connected to a sleeve 7, and the sleeve 7 is hinged to the second end of the support rod seat 3 via the third rotating shaft 8.
[0025] Specifically, the first telescopic cylinder 9 and the second telescopic cylinder 15 are electric cylinders or hydraulic cylinders. After the first telescopic cylinder 9 extends and retracts, it drives the support rod seat 3 to change its angle, thereby driving the pressure roller 14 to bend the copper pipe. At the same time, the hinge seat 4 can support the first telescopic cylinder 9 to change its angle.
[0026] Furthermore, the pressure roller structure also includes a first limiting piece 11, a first fastening nut 12, and a bearing 13. The inner ring of the pressure roller 14 is sleeved on the support rod 10 through the bearing 13. The first limiting piece 11 and the first fastening nut 12 are located at both ends of the bearing 13. The first limiting piece 11 is fixedly connected to the support rod 10, and the first fastening nut 12 is screwed to the support rod 10 to fasten the bearing 13.
[0027] Specifically, the bearing 13 supports the rotation of the pressure roller 14, and the end of the support rod 10 has a thread that allows the first fastening nut 12 to be screwed on to fasten the bearing 13. The bearing 13 and the pressure roller 14 can be disassembled and replaced, which is convenient for maintenance and can be adapted to copper pipes of different sizes.
[0028] Furthermore, the drive roller structure also includes a second limiting piece 22 and a second fastening nut 23. The second limiting piece 22 and the second fastening nut 23 are located at both ends of the drive roller 24. The second limiting piece 22 is fixedly connected to the transmission shaft 19, and the second fastening nut 23 is screwed to the transmission shaft 19 to fasten the drive roller 24.
[0029] Specifically, the second limiting plate 22 and the second fastening nut 23 cooperate to keep the drive roller 24 on the connecting post 21. The end of the second limiting plate 22 has a thread that allows the second fastening nut 23 to be screwed on to fasten the drive roller 24. The drive roller 24 can be replaced.
[0030] Furthermore, the output end of the second telescopic cylinder 15 is fixedly connected to the support rod 10 via the connecting block 16. The support 2 is provided with a sliding groove 18 for avoiding the support rod 10, and a slider 17 that can slide and cooperate with the sliding groove 18 is fixedly connected to the support rod 10.
[0031] Specifically, the second telescopic cylinder 15 is securely connected to the support rod 10 via the connecting block 16, and the slider 17 can guide the lifting and lowering of the support rod 10, maintaining the stability of the lifting and lowering of the support rod 10.
[0032] Furthermore, a polygonal cross-section connecting post 21 is provided on the outer wall of the drive shaft 19, and the inner ring of the drive roller 24 is adapted to the connecting post 21 and can be sleeved on the connecting post 21.
[0033] Specifically, the drive roller 24 is mounted on the polygonal connecting post 21 to prevent the drive roller 24 from rotating on its own. After the drive shaft 19 drives the drive roller 24 to rotate, the drive roller 24 conveys the copper pipe.
[0034] In the above structure, the copper tube to be bent passes between the pressure rollers 14 and the drive rollers 24 distributed vertically. The first telescopic cylinder 9 and the second telescopic cylinder 15 are activated to extend. The first telescopic cylinder 9 adjusts the angle of the support rod seat 3 so that the pressure rollers 14 apply pressure to the copper tube. The second telescopic cylinder 15 drives the pressure rollers 14 to press down and apply pressure to the copper tube. At this time, the motor 20 is started to drive the transmission shaft 19 to rotate, so that the transmission shaft 19 drives the drive rollers 24 to rotate through the connecting column 21. Then the copper tube is transported so that the copper tube is gradually formed into an arc shape. The first telescopic cylinder 9 and the second telescopic cylinder 15 gradually extend to obtain the required arc-shaped copper tube. After bending, the first telescopic cylinder 9 and the second telescopic cylinder 15 retract to their original positions, making it easy to remove the copper tube.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
