Then, the bending servo motor 291 is started to drive the bending mandrel 292 to rotate, so that the folding angle pin 295 drives the folding angle sleeve 296 to rotate around the bending sleeve 294, thereby bending the end of the long horizontal line by 90°. Finally, the clamping jaw device 28 releases the long horizontal line, and the moving plate 211 drives the clamping jaw device 28 and the two bending devices 29 to move below the bent frame workbench 22, so that the bent frame monomer can be released and transferred to the next process.

After the adjustment is in place, the locking screws are used to fasten the locking connecting seat 217 and the movable plate 211, thereby locking the bending position of the two bending devices 29 on the long horizontal line.

[0061] The first slide rail assembly 245, the second slide rail assembly 215 and the third slide rail assembly 216 are mainly composed of movable slide rails and fixed sliders.

[0062] The frame 21 is provided with a plurality of bent frame wire plates 218 between the bent frame wiring groove 23 and the transplanting wiring groove 25. The plurality of bent frame wire plates 218 are evenly spaced along the length direction of the long horizontal line, and a wire inclined surface 2181 is provided on the outer side of the bent frame wire plates 218. When the long horizontal line in the bent frame wiring groove 23 falls into the transplanting wiring groove 25, the plurality of bent frame wire plates 218 help to improve the accuracy of blanking and ensure that the long horizontal line can fall into the transplanting wiring groove 25.

[0063] The frame 21 is also provided with a wiring side baffle 219, which is arranged on the side of the bent frame wiring slot 23 opposite to the feeding end; when the long horizontal line that has just been cut is sent into the bent frame wiring slot 23, the wiring side baffle 219 is used to stop and limit the long horizontal line to prevent the long horizontal line from sliding out of the bent frame wiring slot 23, and the length of the transplanting wiring slot 25 is greater than the bent frame wiring slot 23, and the transplanting wiring slot 25 is connected to the two mounting plates of the frame 1, and the mounting plates also have the function of the wiring side baffle 219.

[0066] The inner limit structure also includes inner limit plates 37 arranged on both sides of the rotating dividing wheel 34. The inner limit plates 37 are mounted on the rotating shaft 32 through a bushing and form an arc-shaped feeding limit gap 301 with the corresponding upper baffle plate 35. The inner limit plates 37 are integrally formed with the corresponding horizontal line storage plates 36 and are connected to the horizontal line drop frame 31 through the horizontal line storage plates 36. The rotating dividing wheel 34 provides power for transplanting the short horizontal lines. The inner limit plates 37 cooperate with the upper baffle plate 35 to limit the two ends of the short horizontal line, so that the two ends of the short horizontal line can also move along the feeding path.

[0067] At least two horizontal wire storage plates 36 are arranged on both sides of the rotating material distribution wheel 34, and the ends of the two horizontal wire storage plates 36 close to the rotating material distribution wheel 34 are provided with horizontal wire limiting parts 362, and the outer side surfaces of the horizontal wire limiting parts 362 are connected with insulating plates 38 and strong magnet plates 39 in sequence; When the short horizontal line falls into the feeding inclined surface 361 (such as Figure 8 and Fig. 9 The short horizontal line automatically slides toward the rotating material distribution wheel 34. At the same time, the magnetic field generated by the strong magnet plate 39 attracts the nearest short horizontal line, so that the nearest short horizontal line is tightly pressed against the wheel surface of the rotating material distribution wheel 34 until one of the feeding slots 341 passes by, causing the short horizontal line to fall into the feeding slot 341 (such as Figure 8 and Fig. 9 Middle M2 marker, Figure 2 and Figure 3 The M3 and M4 marks indicate that the short horizontal wire is transported along the feeding path in the feeding trough 341).

[0068] The outer end of the upper baffle plate 35 is provided with an upper limit inclined surface 351, and the inner limit plate 37 is provided with a lower baffle plate 310 extending outward, and the top surface of the lower baffle plate 310 is provided with a lower limit inclined surface 3101, and a lower material trough 302 for receiving the feeding limit gap 301 is formed between the lower limit inclined surface 3101 and the upper limit inclined surface 351; the lower material trough 302 formed by this structure can make the short horizontal line escape from the feeding limit gap 301 (such as Figure 8 and Fig. 9 The workpiece is transported to the welding station of the welding mechanism 4, thereby increasing space and facilitating the arrangement of the workpiece transport mechanism 7 on the equipment.

[0069] The rotating material dividing wheel 34 comprises a rotating wheel 342 and material dividing wheels 343 which are adjustably connected to the two sides of the rotating wheel 342.

The inner opening grooves 341a and the outer opening grooves 341b correspond to each other one by one and constitute a feeding groove 341. The feeding groove 341 changes its size according to the overlapping area of ​​the inner opening grooves 341a and the outer opening grooves 341b. like Fig.11 As shown, when the overlapping area of ​​the inner opening groove 341a and the outer opening groove 341b is smaller, the short horizontal line of the feed groove 341 is directly smaller. Fig.12 After the complete overlap as shown, the feed slot 341 is maximized; when adjusting the relative positions of the rotating wheel 342 and the dividing wheel 343, a plurality of elongated holes 3421 are opened circumferentially on the rotating wheel 342, and an external fastening hole 3431 is opened on the dividing wheel 343 corresponding to the elongated holes 3421. After fasteners such as bolts are passed through the external fastening hole 3431 and the elongated hole 3421, the rotating wheel 342 and the dividing wheel 343 can be fixed, thereby changing the overlapping area of ​​the inner opening slot 341a and the outer opening slot 341b.

[0070] In addition, in the present embodiment, the feed trough 341 is V-shaped and includes a short groove surface and a long groove surface. The short groove surface is close to the side of the feeding slope 361. The feed trough 341 of this shape can better receive the short horizontal lines in the early stage and guide the short horizontal lines to the discharge trough 302 more quickly in the later stage.
