[0020] See also Figure 1-4The embodiment provided by the present invention is an automated continuous children's bicycle frame bending production equipment, including a workbench 1 for support, a storage box 2 is fixedly provided on the top of the workbench 1 by bolts, a cylinder 3 is fixedly provided on the end of the storage box 2 by bolts, a slot 4 is provided on the top of the cylinder 3 for placing the frame raw materials, the frame raw materials are usually aluminum alloy pipes, the aluminum alloy pipes are existing technology and will not be described in detail here, a slide 5 is provided on the other end of the storage box 2 for the pipe to slide, and the internal size of the slide 5 is the same as that of the cylinder 3. The external dimensions of the pipeline are adapted, and the chute 5 is connected to the bottom end of the slot 4, so that the pipeline can fall from the slot 4 into the interior of the chute 5 in sequence. A limit seat 6 is fixed in the middle of the workbench 1, and a hole groove 12 is opened on the side wall of the limit seat 6. The hole groove 12 and the chute 5 are located at the same horizontal position for the frame to be plugged in, thereby limiting the displacement of the end of the pipeline. The output end of the cylinder 3 passes through the storage box 2 and is fixed with a piston rod 16. The top of the workbench 1 is fixed with a bending cylinder 7, and the top of the bending cylinder 7 is fixed with a servo motor 8. A groove 9 is provided on the side wall of the servo motor 8 near the horizontal position of the chute 5. A bending cylinder 2 10 is fixed to the output end of the top of the groove 9. The bending cylinder 17 and the bending cylinder 2 10 are both made of stainless steel and are cylindrical. The bending cylinder 17 and the bending cylinder 2 10 are tangent to each other in sequence. A groove 2 11 is provided on the side wall of the bending cylinder 2 10 near the groove 9. The groove 2 11 is adapted to the internal dimensions of the groove 9 and the chute 5 in sequence for pipe clamping. When the cylinder 13 is operated to start, the piston rod 16 can be driven to extend and retract. The aluminum alloy pipe clamped in the slide groove 5 can slide horizontally. The internal size of the slide groove 5 is adapted to the external size of the aluminum alloy pipe, thereby improving the stability of the pipe movement, so that the pipe is clamped between groove 1 9 and groove 2 11 through the hole groove 12. When the operator starts the servo motor 1 8 to drive the bending cylinder 2 10 to rotate clockwise, the pipe can be bent and formed inside the groove 1 9 and groove 2 11, thereby improving the efficiency of loading and positioning when the frame is bent, thereby improving the bending and forming efficiency of the frame.

[0021] The limiting seat 6 is rotatably connected to the side wall of the storage box 2 with a mounting seat 13. Two cylinders 14 are symmetrically fixed on the side wall of the mounting seat 13. The output ends of the cylinders 14 pass through the mounting seat 13 and are fixed with claws 15. The claws 15 are all arc-shaped and symmetrically distributed. Starting the cylinders 14 can push the claws 15 to move toward each other, thereby clamping the pipe, thereby improving the stability of the end of the pipe when it is bent.

[0022] A second slot 17 is provided on the side wall of the limit seat 6 for the mounting seat 13 to be engaged. The second slot 17 is connected to the hole slot 12 and is concentric. The internal size of the second slot 17 is adapted to the external size of one end of the mounting seat 13, which improves the rotation stability of the mounting seat 13. A servo motor 2 18 is fixedly provided inside the limit seat 6 near the top of the hole slot 12. A gear wheel 19 is fixedly provided at the output end of the servo motor 2 18. A tooth groove 20 is fixedly provided on the inner side wall of the mounting seat 13 near the gear wheel 19. The tooth groove 20 is engaged with the gear wheel 19. Starting the servo motor 2 18 can drive the gear wheel 19 to rotate. The gear wheel 19 and the tooth groove 20 cooperate to drive the cylinder 2 14 to rotate synchronously with the mounting seat 13, thereby rotating the pipeline, thereby facilitating the change of the bending angle.

[0023] Working principle: When this type of automated continuous children's bicycle frame bending production equipment is in use, the operator first connects an external power supply and evenly places the frame raw materials to be processed inside the groove 4. The frame raw materials are aluminum alloy tubes. Under the action of gravity, the aluminum alloy tubes can fall into the inside of the slide 5 in sequence. When the cylinder 13 is started, the piston rod 16 can be driven to extend and retract, so that the aluminum alloy tube can slide inside the slide 5. The internal size of the slide 5 is compatible with the external size of the aluminum alloy tube, thereby improving the stability of the pipeline movement, so that the pipeline passes through the mounting seat 13 and the hole groove 12 and is clamped between the groove 1 9 and the groove 2 11. When the operator starts the servo motor 18 to drive the bending cylinder 2 10 to rotate clockwise, the pipeline can be bent and formed inside the groove 1 9 and the groove 2 11, thereby improving the efficiency of loading and positioning of the frame during bending, thereby improving the efficiency of the frame bending and forming.

[0024] Secondly, the two air cylinders 14 are started to push the claws 15 to move toward each other to clamp the pipe, thereby improving the stability of the end portion when the pipe is bent.

[0025] Finally, starting the servo motor 2 18 can drive the gear wheel 19 to rotate. The gear wheel 19 cooperates with the tooth groove 20 to drive the cylinder 2 14 to rotate synchronously with the mounting base 13, thereby rotating the pipe, thereby facilitating the change of the bending angle.
