[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] refer to Figures 1 to 5 As shown, the automatic frame bending device includes a frame 21, on which a bending worktable 22 is provided. The frame 21 is provided with a wiring groove assembly for receiving and transferring the long horizontal wires to the bending worktable 22, and a bending frame flipping device for controlling the up-and-down flipping of the wiring groove assembly. The lower side of the bending worktable 22 is provided with a moving plate 211 and a processing lifting device for controlling the up-and-down movement of the moving plate 211. The moving plate 211 is provided with a gripper device 28 for clamping the long horizontal wires on the bending worktable 22, and a bending device 29 for bending the long horizontal wires to be bent symmetrically at both ends to form a bent frame.

[0024] This automatic frame bending device can automatically feed and bend long horizontal lines in 2D, forming curved frames. The operation is precise and error-free, requiring no frequent manual intervention. This reduces labor costs by minimizing manual labor positions and can significantly improve the production efficiency and accuracy of frame equipment.

[0025] The wiring trough assembly includes a curved frame wiring trough 23 and a transplanting wiring trough 25 rotatably connected to the frame 21. The curved frame flipping device includes a first flipping device 24 and a second flipping device 26. The first flipping device 24 is drivenly connected to the curved frame wiring trough 23. The transplanting wiring trough 25 is disposed between the curved frame wiring trough 23 and the curved frame workbench 22. The second flipping device 26 is drivenly connected to the transplanting wiring trough 25.

[0026] The bending frame workbench 22 is equipped with side pusher plates 212 on both the left and right sides. The frame 21 is equipped with pusher cylinders 213 that control the relative movement of the pusher plates 212 on both sides. When the long horizontal line falls from the transfer connection slot 25 onto the bending frame workbench 22, the pusher cylinders 213 drive the pusher plates 212 on both sides to move in opposite directions, thereby arranging the long horizontal line to the workpiece position on the bending frame workbench 22 to ensure the accuracy of the bending frame.

[0027] Two gripper devices 28 are provided, positioned one on the left and one on the right in the middle of the bending frame worktable 22. After the long horizontal line falls into the bending frame worktable 22, the two gripper devices 28 clamp the middle part of the long horizontal line, keeping the middle part of the long horizontal line straight during bending and preventing it from bending. The gripper device 28 includes a gripper cylinder 281, and the output end of the gripper cylinder 281 is connected to two mechanical grippers 282.

[0028] Two bending devices 29 are provided, and the two bending devices 29 are respectively located on the left or right side of the gripper device. After the long horizontal line falls into the bending frame workbench 22, the two bending devices 29 can simultaneously bend the two ends of the long horizontal line by 90°, thereby forming a bending frame unit in the shape of "U".

[0029] Specifically, each bending device 29 includes a longitudinal bending servo motor 291. The output shaft of the bending servo motor 291 is fixed with a bending mandrel 292. A bending pin 293 is provided at the center of the bending mandrel 292. A bending sleeve 294 is fitted onto the bending pin 293. An angle pin 295 that rotates around the bending pin 293 is provided on the side of the bending pin 293. An angle sleeve 296 is fitted onto the angle pin 295. The bending sleeve 294 and the angle sleeve 296 are rotatably connected to the bending pin 293 and the angle pin 295, respectively. During bending, this can reduce wear on the long horizontal line and maintain the integrity of the surface of the long horizontal line.

[0030] During processing, after the long horizontal line on the bending frame worktable 22 is clamped by the gripper device 28, the end of the long horizontal line is held between the bending sleeve 294 and the angle sleeve 296. Then, the bending servo motor 291 is started to drive the bending mandrel 292 to rotate, so that the angle nail 295 drives the angle sleeve 296 to rotate around the bending sleeve 294, thereby bending the end of the long horizontal line by 90°. Finally, the gripper device 28 releases the long horizontal line, and the moving plate 211 moves the gripper device 28 and the two bending devices 29 to below the bending frame worktable 22, so that the bending frame unit can be released from fixation and can be transferred to the next process.

[0031] The first flipping device 24 includes a transverse base 241, a wiring swing rod 242 rotatably connected to the transverse base 241, and a wiring flipping cylinder 243 fixed to the transverse base 241. The transverse base 241 slides laterally on the frame 21 via a first slide rail assembly 245. The wiring swing rod 242 is fixedly connected to the curved frame wiring groove 23 via several wiring swing blocks 246. The curved frame wiring groove 23 has a V-shaped cross-section, and the two ends of the wiring swing rod 242 are provided with gear 247. The telescopic shaft of the wiring flipping cylinder 243 is provided with a longitudinal rack 248 that meshes with gear 247. The first flipping device 24 also includes a rodless cylinder 2410, which is fixed to the frame 1 and connected to the transverse base 241. The rodless cylinder 2410 drives the transverse base 241 to move left and right.

[0032] The second flipping device 26 includes a transplanting swing rod 261 and a transplanting flipping cylinder 262 fixed on the frame 21. The transplanting wiring groove 25 is fixed on one side of the transplanting swing rod 261, and the transplanting swing rod 261 is rotatably connected to the frame 21 and has gears 263 at both ends. The telescopic shaft of the transplanting flipping cylinder 262 is provided with a transverse rack 264 that meshes with the gears 263. In addition, the transverse shift seat 241 and the frame 21 are also provided with rack guide sleeves 249 and 265 that form a linear sliding fit with the longitudinal rack 248 or the transverse rack 264.

[0033] Based on the above structure, after the newly cut long horizontal wire is fed into the bending frame wiring groove 23, the wiring tilting cylinder 243 starts to drive the bending frame wiring groove 23 to tilt downward, thereby pouring out the long horizontal wire in the bending frame wiring groove 23. Then, the wiring tilting cylinder 243 drives the bending frame wiring groove 23 to reset, waiting for the next long horizontal wire to be fed in. At this time, the slot of the transplanting wiring groove 25 is facing upward and is located in the path of the long horizontal wire falling, and it receives the long horizontal wire poured out of the bending frame wiring groove 23. Then, the transplanting tilting cylinder 262 starts to drive the transplanting wiring groove 25 to tilt downward, thereby pouring the long horizontal wire in the transplanting wiring groove 25 onto the bending frame worktable 22.

[0034] The frame 21 includes a fixed plate 214, and the movable plate 211 is longitudinally slidably connected to one side of the fixed plate 214 via a second slide rail assembly 215. A third slide rail assembly 216 is provided on one side of the movable plate 211, and a locking connecting seat 217 that slides laterally is connected to the third slide rail assembly 216. The bending device 29 is fixed on the locking connecting seat 217. The processing lifting device includes a lifting cylinder 210, which is connected to the bottom of the fixed plate 214 and its telescopic shaft is connected to the movable plate 211.

[0035] The distance between the two bending devices 29 can be adjusted laterally using the third slide rail assembly 216, allowing the automatic bending frame device to be adjusted arbitrarily according to the specifications of the bending frame, making the automatic bending frame device more applicable and more practical. After the adjustment is in place, the connecting seat 217 and the moving plate 211 are tightened with locking screws, thereby locking the bending position of the two bending devices 29 on the long horizontal line.

[0036] The first slide rail assembly 245, the second slide rail assembly 215, and the third slide rail assembly 216 are mainly composed of a movable slide rail and a fixed slide block. The transverse sliding seat 241, the movable plate 211, and the locking connecting seat 217 are slidably connected to the frame 21, or the fixed plate 214, or the movable plate 211 respectively through the cooperation of the movable slide rail and the fixed slide block.

[0037] The frame 21 has several curved frame guide plates 218 arranged between the curved frame wiring groove 23 and the transplant wiring groove 25. The curved frame guide plates 218 are evenly distributed along the length of the long horizontal line, and the outer side of the curved frame guide plates 218 is provided with a guide inclined surface 2181. When the long horizontal line in the curved frame wiring groove 23 falls into the transplant wiring groove 25, the several curved frame guide plates 218 help to improve the accuracy of material dropping and ensure that the long horizontal line can fall into the transplant wiring groove 25.

[0038] The frame 21 is also provided with a wiring side baffle 219, which is located on the side of the curved frame wiring groove 23 opposite to the feed end. When the long horizontal wire that has just been cut is fed into the curved frame wiring groove 23, the wiring side baffle 219 is used to stop and limit the long horizontal wire to prevent it from sliding out of the curved frame wiring groove 23. The length of the transplant wiring groove 25 is greater than that of the curved frame wiring groove 23, and the transplant wiring groove 25 is connected to the two mounting plates of the frame 1. The mounting plates also serve the function of the wiring side baffle 219.

[0039] In this embodiment, the bending frame workbench 22 includes a middle table panel 221, a left table panel 222, and a right table panel 223. The left table panel 222 and the right table panel 223 are provided with mandrel clearance openings 224 corresponding to the bending device 29. The middle table panel 221 and the left table panel 222 or the right table panel 223 are provided with side gripper clearance positions 225 corresponding to the gripper device 28. This enables the gripper device 28 to hold the long horizontal line in the overhead position of the bending frame workbench 22, and enables the bending device 29 to bend the long horizontal line in the overhead position of the bending frame workbench 22.
