[0030] The bending device 3 includes a bending fixed plate 31, a linear guide 32 is fixedly connected to the surface of the bending fixed plate 31 by bolts, a plurality of sliders 33 are movably connected to the linear guide 32, a first movable plate 34 and a second movable plate 35 are respectively fixedly connected to the surface of the sliders 33 by bolts, a first cylinder 361 and a second cylinder 362 are symmetrically arranged on both sides of the surface of the bending fixed plate 31, the first cylinder 361 and the second cylinder 362 are respectively connected to the first movable plate 34 and the second movable plate 35 by transmission, and the first cylinder 361 and the second cylinder 362 drive the two first movable plates 34 and the second movable plate 35. The plate 34 and the second movable plate 35 can be moved to make them closer or separate. The top of the first movable plate 34 is fixedly connected to the first mold 391 and the first bending mechanism, and the top of the second movable plate 35 is fixedly connected to the second mold 392 and the second bending mechanism. When the pipe fitting 9 moves to the positioning groove 21, the first cylinder 361 and the second cylinder 362 drive the first movable plate 34 and the second movable plate 35 to move closer to each other. At this time, the first mold 391 and the second mold 392 are closed to clamp one end of the pipe fitting 9, and then the first bending mechanism and the second bending mechanism are used to perform two bending operations to complete the processing of the pipe fitting 9.

[0031] Specifically, the first bending mechanism includes a first bending cylinder 371, the output shaft of the first bending cylinder 371 is transmission-connected to a connecting plate 372, one side of the connecting plate 372 is bolt-fixedly connected to a rack 373, the top end of the first movable plate 34 is bolt-fixedly connected to a first fixed block 374, the side of the first fixed block 374 is rotatably connected to a gear 375, the gear 375 is meshed with the rack 373, the side of the gear 375 is fixedly connected to a connecting shaft 376, one end of the connecting shaft 376 is fixedly connected to a first bending wheel 377, and the first bending wheel 377 is arranged above the first mold 391. When the pipe fitting 9 is moved to the positioning groove 21 by the transfer mechanism 4, the first cylinder 361 and the second cylinder 362 drive the first mold 391 and the second mold 392 to move together, and the first mold 391 and the second mold 392 clamp the end of the pipe fitting 9. At this time, the pipe fitting 9 is between the first mold 391 and the first bending wheel 377. The rack 373 is driven to move by the first bending cylinder 371, and the rack 373 drives the gear 375 to rotate. The rotation of the gear 375 drives the connecting shaft 376 to move in an arc trajectory, thereby driving the first bending wheel 377 to move. During the movement of the first bending wheel 377, the end of the pipe fitting 9 is bent so that it is bent along the arc side of the first mold 391, completing the first bending operation.

[0032] Specifically, the second bending mechanism includes a second bending cylinder 381, which is fixedly connected to the top of the second movable plate 35 through a cylinder fixing plate 382, ​​and the output shaft of the second bending cylinder 381 is connected to the second bending wheel 383, and the top of the second movable plate 35 is fixedly connected to the second fixing block, and the second mold 392 is fixedly connected to the second fixing block, and the second bending wheel 383 is arranged below the second mold 392. After the first bending operation is completed, the end of the pipe 9 is moved to the bottom of the first mold 391 and the second mold 392 after bending, and the second bending wheel 383 is driven by the second bending cylinder 381 to move in the direction of the first mold 391, and the pipe 9 is pushed by the second bending wheel 383 to be bent and deformed, and the second bending operation is completed.

[0033] Among them, the side surfaces of the first mold 391 and the second mold 392 are arc-shaped surfaces, and a first guide groove is provided on the adjacent side of the first mold 391 and the second mold 392. After the two first guide grooves of the first mold 391 and the second mold 392 are combined together, an arc-shaped groove with a semicircular cross-section is formed, which is matched with the bottom of the pipe fitting 9 after being combined together. The upper part of the pipe fitting 9 is extruded by the first bending wheel 377 and bent along the direction of the first guide groove to ensure that the bent shape meets the requirements; a second guide groove is provided at the bottom of the first mold 391, and the end of the pipe fitting 9 is bent along the direction of the second guide groove after being pushed by the second bending wheel 383 to ensure that the bending shape meets the processing requirements.

[0034] Furthermore, the first movable plate 34 is bolted and fixedly connected with a linear bearing 310, and the linear bearing 310 is embedded with a guide light shaft 311, and one end of the guide light shaft 311 is fixedly connected to the connecting plate 372. The guide light shaft 311 assists in guiding, ensuring that the rack 373 moves in an accurate direction.

[0035] Specifically, it also includes a tube pressing mechanism, which includes a cylinder fixing frame 61, and the cylinder fixing frame 61 is bolted and fixedly installed on the surface of the frame 1, and the top bolt of the cylinder fixing frame 61 is fixedly connected with a tube pressing cylinder 62, and the output shaft of the tube pressing cylinder 62 is fixedly connected with a pressing plate 63, and the pressing plate 63 is arranged above the bending device 3. When the first mold 391 and the second mold 392 are close to clamp the pipe 9, the pressing plate 63 is driven by the tube pressing cylinder 62 to move downward and press the top of the pipe 9, so as to avoid the pipe 9 being pressed upward during the bending process, which affects the bending effect.

[0036] Furthermore, it also includes a pushing mechanism, which includes a pushing guide rail 71, and the pushing guide rail 71 is movably connected with a pushing mounting block 72, and the pushing mounting block 72 is fixedly installed on the pushing guide rail 71 by bolts. The position of the pushing mounting block 72 on the pushing guide rail 71 can be adjusted, and then fixed by bolts, so as to adjust the position of the pushing cylinder 73, and the pushing mounting block 72 is fixedly connected with the pushing cylinder 73, and the output shaft of the pushing cylinder 73 is fixedly connected with a pushing head 74, and the cylinder fixing frame 61 is fixedly connected with a limiting column 75 at a position corresponding to the pushing head 74. After the pipe fitting 9 is placed in the positioning groove 21, the pushing head 74 is driven to move by the pushing cylinder 73, and the pushing head 74 pushes the pipe fitting 9 to move, so that one end of the pipe fitting 9 is set against the limiting column 75, thereby adjusting the position of the pipe fitting 9 to ensure its accurate bending position.

[0037] Specifically, the transfer mechanism 4 includes a first linear motion module 41 and a second linear motion module 42 fixedly connected to the inside of the frame 1, the movement direction of the first linear motion module 41 is parallel to the direction of the positioning plate 2, the movement direction of the second linear motion module 42 is perpendicular to the movement direction of the first linear motion module 41, the first linear motion module 41 is transmission-connected to the second linear motion module 42, the output shaft of the second linear motion module 42 is transmission-connected to a lifting plate 43, the two sides of the surface of the lifting plate 43 are fixedly connected to a transfer plate 44, and a plurality of positioning grooves 45 are provided on the transfer plate 44. The first linear motion module 41 and the second linear motion module 42 in the present embodiment are motion modules in the prior art, which are guided by guide rails and sliders 33 and driven by cylinders as power. The specific structure and working principle thereof will not be described in detail here. The lifting plate 43 is driven to move forward and backward by the first linear motion module 41, and the lifting plate 43 is driven to move up and down by the second linear motion module 42, thereby driving the transfer plate 44 to move forward and backward and up and down. When working, firstly, one end of the transfer plate 44 is driven to move below the feeding mechanism 5 by the first linear motion module 41, and then the transfer plate 44 is driven to rise by the second linear motion module 42, and the pipe 9 falls into the positioning groove 45 on the transfer plate 44. At this time, the first linear motion module 41 drives the transfer plate 44 to move forward and backward and up and down. The carrier plate 44 moves in the direction away from the feeding mechanism 5, driving the pipe fitting 9 to move above the positioning groove 21, and the second linear motion module 42 drives the transfer plate 44 to move downward to make the pipe fitting 9 fall into the positioning groove 21. After the transfer plate 44 continues to move downward to disengage the pipe fitting 9, the pipe fitting 9 is transferred to the positioning groove 21. At this time, the first linear motion module 41 moves in the opposite direction for the next feeding. During the next feeding, the transfer plate 44 drives the pipe fitting 9 of the feeding mechanism 5 to continue to be transferred to the positioning groove 21. At the same time, one end of the transfer plate 44 is located below the positioning groove 21. When it rises, it drives the processed pipe fitting 9 to disengage from the positioning groove 21, and continues to move forward to load while unloading the processed pipe fitting 9. A collection box can be placed at the end of the frame 1.

[0038] Specifically, the feeding mechanism 5 includes two feeding plates 51 arranged opposite to each other, and the inner side of the feeding plates 51 is fixedly connected with an inclined material guide channel 52. The two ends of the pipe 9 are respectively placed in the material guide channel 52, and the pipe 9 can fall down in sequence along the material guide channel 52. The bottom of the feeding plate 51 is fixedly connected with a material receiving cylinder 53, and the output shaft of the material receiving cylinder 53 is fixedly connected with a material receiving plate 54, and the material receiving plate 54 is arranged at the output end of the material guide channel 52. The material receiving cylinder 53 drives the material receiving plate 54 to close the material guide channel 52. When the transfer mechanism 4 carries the pipe 9 at the bottom, the material receiving cylinder 53 drives the material receiving plate 54 to descend so that the pipe 9 at the bottom rolls onto the transfer mechanism 4, and then quickly closes the discharge end of the material guide channel 52, waiting for the next material discharge.

[0039] Furthermore, a controller 8 is fixedly connected to the surface of the rack 1 , and the controller 8 is a PLC controller 8 , through which the overall operation of the device is controlled.
