Description

Technical Field

[0001] This utility model relates to the field of bending frame production equipment, specifically an automatic bending frame welding machine. Background Technology

[0002] With the development of industry, people's perception of wire shapes is no longer limited to simple straight lines. As a result, many frame products made by bending wire have appeared on the market. The production of frame products often involves processes such as wire coil feeding, straightening, 2D bending, welding, 3D bending, punching, and final stacking. Currently, production is generally carried out manually. In mass production, manually processed metal wire suffers from uneven deformation, large internal stress, and inadequate requirements for spacing, bending accuracy, and welding points. This increases labor intensity and reduces safety. Moreover, manual bending of frames requires high labor costs, the processing steps are cumbersome, and quality is difficult to control, resulting in low production efficiency and failure to meet production needs. Therefore, a fully automated production equipment is proposed to address the above-mentioned processes. Utility Model Content

[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] refer to Figure 1As shown, the automatic bending and welding machine includes a machine base 1, on which a workpiece conveying table 9 for conveying workpieces is provided. Along the workpiece conveying direction, the machine base 1 is sequentially provided with a bending frame mechanism 2 for bending the long horizontal lines to be bent symmetrically at both ends to form a bent frame, two sets of horizontal line unloading mechanisms 3 for arranging several short horizontal lines at intervals on the bent frame, and two sets of welding mechanisms 4 for welding the two ends of the short horizontal lines to the bent frame to form a semi-finished product, a tail hook forming mechanism assembly 5 for bending the tail hook of the semi-finished product into a finished frame, a discharge and stacking mechanism 6 for transferring the finished frame material, a workpiece handling mechanism 7 for sequentially transporting the bent frame, or semi-finished product, or finished frame on the workpiece conveying table 9 to each mechanism, and a frame storage and output mechanism 8 for storing and outputting the finished frame.

[0051] refer to Figures 2 to 6 As shown, the bending frame mechanism 2 includes a frame 21, on which a bending frame worktable 22 is provided. The frame 21 is provided with a wiring groove assembly for receiving the cut and shaped long horizontal line and transferring the long horizontal line to the bending frame 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 frame worktable 22 is provided with a moving plate 211 and a processing lifting device for controlling the up and down lifting of the moving plate 211. The moving plate 211 is provided with a gripper device 28 for clamping the long horizontal line on the bending frame worktable 22 and a bending device 29 for bending the long horizontal line to be bent symmetrically at both ends to form a bending frame.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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".

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] refer to Figures 7 to 14As shown, the horizontal wire dropping mechanism 3 includes a horizontal wire dropping frame 31. The horizontal wire dropping frame 31 is provided with a rotating shaft 32 and a dropping power device 33 for driving the rotating shaft 32 to rotate. The rotating shaft 32 is provided with an inner limiting structure. The inner limiting structure includes at least a rotating material distribution wheel 34. The edge of the rotating material distribution wheel 34 is provided with a plurality of circumferentially distributed feeding grooves 341. The inner limiting structure is provided with an upper baffle 35 along the outer side of the feeding path to limit the horizontal wire within the feeding grooves 341. The horizontal wire dropping frame 31 is also provided with a plurality of horizontal wire storage plates 36. The horizontal wire storage plates 36 extend to one side of the inner limiting structure, and the top surface of the horizontal wire storage plates 36 is provided with a feeding inclined surface 361 inclined to the feeding grooves 341.

[0068] The inner limiting structure also includes inner limiting plates 37 disposed on both sides of the rotating distributing wheel 34. The inner limiting plates 37 are sleeved on the rotating shaft 32 through bushings and form an arc-shaped feeding limiting gap 301 between them and the corresponding upper baffle 35. The inner limiting plates 37 are integrally formed with the corresponding horizontal line storage plate 36 and are connected to the horizontal line drop frame 31 through the horizontal line storage plate 36. The rotating distributing wheel 34 provides the power for transplanting the short horizontal lines. The inner limiting plates 37 and the upper baffle 35 cooperate to limit the two ends of the short horizontal lines, so that the two ends of the short horizontal lines also move along the feeding path.

[0069] At least two horizontal line storage plates 36 are respectively arranged on both sides of the rotating material distribution wheel 34, and the ends of the two horizontal line storage plates 36 near the rotating material distribution wheel 34 are provided with horizontal line limiting parts 362. The outer side of the horizontal line limiting parts 362 is connected to an insulating plate 38 and a strong magnet plate 39 in sequence.

[0070] When the short horizontal line falls into the feeding slope 361 (as shown) Figure 8 and Figure 9 (M1 marking), the short horizontal line automatically slides towards the rotating dispensing wheel 34. At the same time, the magnetic field generated by the strong magnetic plate 39 attracts the nearest short horizontal line, causing it to press tightly against the surface of the rotating dispensing wheel 34, until one of the feeding troughs 341 passes by, causing the short horizontal line to fall into the feeding trough 341 (e.g., M1 marking). Figure 8 and Figure 9 M2 mark, Figure 2 and Figure 3 The M3 and M4 markings indicate that the short horizontal line is conveyed along the feeding path in the feeding trough 341. This structure utilizes a strong magnetic plate 39 to ensure the success rate of the short horizontal line sliding into the feeding trough 341.

[0071] The upper baffle 35 has an upper limit slope 351 at its outer end, and the inner limit plate 37 has a lower baffle 310 extending outward. The top surface of the lower baffle 310 has a lower limit slope 3101, and a feeding groove 302 is formed between the lower limit slope 3101 and the upper limit slope 351 to receive the feeding limit gap 301. The feeding groove 302 formed by this structure allows the short horizontal line to disengage from the feeding limit gap 301 (e.g., Figure 8 and Figure 9 (M5 mark) and transported to the welding station of welding mechanism 4, increasing space to facilitate the arrangement of workpiece handling mechanism 7 on the equipment.

[0072] The rotating material distribution wheel 34 includes a rotating wheel 342 and two material distribution wheels 343 that are adjustablely connected to the two sides of the rotating wheel 342. The rotating wheel 342 and the two material distribution wheels 343 are fixed on the rotating shaft 32 by a shaft clamp. The edges of the rotating wheel 342 and the material distribution wheels 343 are respectively provided with a plurality of circumferentially distributed inner opening grooves 341a and outer opening grooves 341b. The inner opening grooves 341a and outer opening grooves 341b correspond one to one and form a feeding groove 341. The size of the feeding groove 341 changes according to the overlapping area of ​​the inner opening grooves 341a and outer opening grooves 341b.

[0073] like Figure 11 As shown, the smaller the overlapping area of ​​the inner opening groove 341a and the outer opening groove 341b, the smaller the short horizontal line of the feeding trough 341. When the inner opening groove 341a and the outer opening groove 341b are as shown... Figure 12 When the two parts are fully overlapped, the feeding groove 341 is maximized. When adjusting the relative position of the rotating wheel 342 and the distributing wheel 343, the rotating wheel 342 has several elongated holes 3421 in the circumferential direction, and the distributing wheel 343 has an outer fastening hole 3431 corresponding to the elongated holes 3421. After fasteners such as bolts pass through the outer fastening hole 3431 and the elongated hole 3421, the rotating wheel 342 and the distributing wheel 343 can be fixed, thereby changing the overlap area of ​​the inner opening groove 341a and the outer opening groove 341b.

[0074] In this embodiment, the feeding trough 341 has a V-shaped structure and includes a short trough surface and a long trough surface. The short trough surface is close to one side of the feeding inclined surface 361. The feeding trough 341 with this shape can better receive the short horizontal line in the early stage and guide the short horizontal line to the discharge trough 302 more quickly in the later stage.

[0075] One side of one of the horizontal line storage plates 36 is connected to a first positioning sensor 311, the sensing surface of the first positioning sensor 311 being located below the feeding ramp 361; a second positioning sensor 315 is connected to one of the inner limiting plates 37, the sensing surface of the second positioning sensor 315 being close to the discharge end of the feeding limiting gap 301; the first positioning sensor 311 and the second positioning sensor 315 are used to sense the number of short horizontal lines entering and exiting, and when the first positioning sensor 311 senses that no short horizontal line has fallen into the feeding ramp 361, it can provide a reminder signal or stop the equipment from working.

[0076] The horizontal wire drop frame 31 is also connected to a horizontal wire side baffle 312. The horizontal wire side baffle 312 is located on one side of the inner limiting structure and at least laterally blocks the entire section of the feeding slope 361. The horizontal wire side baffle 312 can limit the end of the short horizontal wire that falls into the feeding slope 361, preventing the short horizontal wire from sliding out of the automatic dropping device and keeping the short horizontal wires on the feeding slope 361 neat.

[0077] The horizontal wire dropping frame 31 includes a front gantry frame 31a and a rear gantry frame 31b. One end of the plurality of horizontal wire storage plates 36 is connected to the front gantry frame 31a, and the rotating shaft 32, the material dropping power device 33 and the upper baffle 35 are connected to the rear gantry frame 31b.

[0078] The front gantry 31a has several hopper connecting plates 313 that are adjustablely connected to the crossbeams of the gantry frame 31a, corresponding to the number of horizontal line storage plates 36. The several horizontal line storage plates 36 are connected one by one to the hopper connecting plates 313 and can slide in an adjustable manner. In addition to the spacing between the horizontal line storage plates 36, the distance between the inner limit plates 37 can also be adjusted at the same time.

[0079] The crossbeam of the rear gantry 31b is provided with a gap slot plate 314, and several upper baffles 35 are adjustablely connected to the bottom surface of the gap slot plate 314. After the position of the inner limit plate 37 is adjusted, the upper baffles 35 can follow the inner limit plate 37 to adjust, so that the automatic horizontal wire unloading device can use short horizontal wires of different lengths to unload, thereby improving the applicability and practicality.

[0080] The material feeding power unit 33 includes a material feeding servo motor 331 and a reducer 332. The material feeding servo motor 331 is fixed on the wire feeding frame 31 through a reducer mounting plate 334. The reducer 332 is connected to the output shaft of the material feeding servo motor 331. The output shaft of the reducer 332 is connected to one end of the rotating shaft 32 through a perforated coupling 333. The working drive of the material feeding servo motor 331 and the reducer 332 rotates at a speed that maintains the temperature, so that the rotating material distribution wheel 34 can continuously transfer short wires, realizing fully automatic material feeding operation.

[0081] It should be noted that the material feeding power unit 33 can also adopt one of the following methods: gear transmission, belt transmission, chain transmission, or linkage transmission.

[0082] refer to Figure 15 As shown, the tail hook forming mechanism assembly 5 includes, along one side of the semi-finished product conveying direction, a bending mechanism 51 for bending one tail end of the frame upward, an outward bending mechanism 52 for bending the upper folded portion of the frame outward, and a flattening mechanism 53 for flattening the outward folded portion of the frame; and along the other side of the semi-finished product conveying direction, a bending mechanism 54 for rolling the other tail end of the frame and an upward bending mechanism 55 for bending the rolled portion of the frame upward.

[0083] In this embodiment, reference Figure 16 As shown, the bending mechanism 51 includes a bending moving platform 511, on which an upper bending cylinder 512 and a lower bending cylinder 513 are provided. A punching seat is connected to the telescopic shaft of both the upper bending cylinder 512 and the lower bending cylinder 513. A guide post 519 is provided on the bending moving platform 511, which is linearly slidingly engaged with the punching seat 514. The upper punching seat 515 is connected to an upper folding die 516. A right punch 5161 is provided on the bottom surface of the upper folding die 516. The lower punching seat 514 is connected to an upper folding die 517. A left punch 5171 is provided on the top surface of the upper folding die 5171. A bending pressure roller 518 is also rotatably connected to the left punch 5171.

[0084] The working principle of the bending mechanism 51 mentioned above:

[0085] The frame is moved from one end to the upper folding mold 516 and the lower folding mold 517. Then, the upper bending cylinder 512 and the lower bending cylinder 513 are activated to push the upper folding mold 516 and the lower folding mold 517 to move relative to each other. At this time, the left punch 5171 and the right punch 5161 overlap left and right, thereby bending the end of the frame upward. During the bending process, the bending roller 518 is used to reduce the wear of the upper folding mold 517 on the frame, so that the surface of the upper folding part remains smooth.

[0086] In this embodiment, reference Figure 17 and Figure 18 As shown, the outward folding mechanism 52 includes an outward folding moving platform 521. The outward folding moving platform 521 is provided with an upper outward folding cylinder 522 and a lower outward folding cylinder 523. The telescopic shaft of the upper outward folding cylinder 522 is connected to an outward folding bottom mold assembly 524. The outward folding bottom mold assembly 524 is provided with a frame clamping structure 525. The telescopic shaft of the lower outward folding cylinder 523 is connected to an outward folding upper mold assembly 526. The outward folding moving platform 521 is provided with a guide post 527 that linearly slides with the outward folding upper mold assembly 526 and the outward folding bottom mold assembly 524. The outward folding upper mold assembly 526 is provided with a pressure plate assembly 528 that abuts against the outward folding bottom mold assembly 524.

[0087] Specifically: the outer folding bottom mold assembly 524 includes an outer folding lower seat 5241 and an outer folding bottom mold 5242 connected to the bottom surface of the outer folding lower seat 5241. An outer folding push head 5243 is laterally slidably connected inside the outer folding bottom mold 5242. A first spring 5244 is provided between the outer folding push head 5243 and the outer folding bottom mold 5242. An outer folding fixing platform 5245 is provided on the outer side of the outer folding bottom mold 5242. A bending shaft 5246 that moves back and forth relative to the outer folding fixing platform 5245 is connected to the outer folding push head 5243.

[0088] The frame clamping structure 525 includes a clamping guide plate 5251 connected to the outside of the outward folding bottom mold 5242. A clamping block 5252 that moves back and forth relative to the outward folding fixing table 5245 is slidably connected on the clamping guide plate 5251. A second spring 5253 is provided between the clamping block 5252 and the clamping guide plate 5251. The front end of the clamping block 5252 is provided with a cavity that matches the shape of the frame. A clamping cavity 5254 is formed between the cavity and the outward folding fixing table 5245.

[0089] The outer folding upper mold assembly 526 includes an outer folding upper seat 5261 and an outer folding upper mold 5262. The outer folding upper mold 5262 extends upward with an outer folding punch 5263 that pushes the outer folding push head 5243 and a clamping punch 5264 that pushes the clamping block 5252.

[0090] The pressure plate assembly 528 includes a pressure plate 5281 and a third spring 5282. The two ends of the pressure plate 5281 are provided with two guide posts 5283, which are linearly slidably connected in the outer folding upper seat 5261. The third spring 5282 abuts against the pressure plate 5281 and the outer folding upper seat 5261.

[0091] The working principle of the above-mentioned outward folding mechanism 52:

[0092] After bending upwards at one end of the frame, the subsequent upward bending section (such as...) Figure 23 The P1 mark is transferred between the outer folding bottom mold 5242 and the outer folding upper mold 5262. Then, the upper outer folding cylinder 522 and the lower outer folding cylinder 523 are activated to push the outer folding bottom mold assembly 524 and the outer folding upper mold assembly 526 to move relative to each other. At this time, the clamping punch column 5264 pushes the inclined surface on the outside of the clamping block 5252 from top to bottom, so that the clamping block 5252 slides laterally toward the outer folding fixing table 5245. After the two come into contact, the upward bending part of the frame is clamped in the clamping cavity 5254.

[0093] Subsequently, the outer bending punch 5263 pushes the outer inclined surface of the outer bending push head 5243 from top to bottom, causing the outer bending push head 524 to slide laterally, while driving the bending shaft 5246 to move towards the outer bending fixed table 5245, thereby bending the upward bending part outward to form a shape. Finally, the bottom bending die assembly 524 and the upper outer bending die assembly 526 are released from the frame.

[0094] In addition, after the bottom folding mold assembly 524 and the top folding mold assembly 526 are engaged, the pressure plate 5281 presses against the bottom surface of the bottom folding mold 5242. When the frame is released, the third spring 5282 assists in separating the bottom folding mold assembly 524 and the top folding mold assembly 526. The first spring 5244 and the second spring 5253 also help to reset the top folding push head 5243 and the clamping block 5252.

[0095] In this embodiment, reference Figure 19 and Figure 20 As shown, the flattening mechanism 53 includes a flattening moving platform 531, on which an upper flattening cylinder 532 and a lower flattening cylinder 533 are provided. The telescopic shafts of the upper flattening cylinder 532 and the lower flattening cylinder 533 are respectively connected to two relatively moving punches 534. The flattening moving platform 531 is provided with a flattening bottom mold 535. An outward folding positioning cavity 5351 is opened in the flattening bottom mold 535, and a punch through hole 5352 is opened on the flattening bottom mold 535 through the frame positioning cavity.

[0096] The aforementioned outwardly folded positioning cavity 5351 has a laterally open triangular structure. The outwardly bent portion of the frame is positioned at the bottom end of the outwardly folded positioning cavity 5351. The punch through hole 5352 is opened on the upper and lower sides of this bottom end. Based on this structure, the working principle of the aforementioned flattening mechanism 53 is as follows:

[0097] After bending outwards at one end of the frame, the subsequent outward bending section (such as...) Figure 23 The P2 mark is positioned at the bottom of the outward folding positioning cavity 5351. Then, the upper flattening cylinder 532 and the lower flattening cylinder 533 are activated to push the upper and lower punches 534 through the punch through-hole 5352, flattening the outwardly bent portion, thereby flattening the outwardly bent portion into a semi-circular flat section (such as...). Figure 23 (P3 mark).

[0098] In this embodiment, reference Figure 21 As shown, the bending mechanism 54 includes a bending moving platform 541, a bending servo motor 542 fixed on the bending moving platform 541, a bending turntable 543 fixed on the rotating shaft of the bending servo motor 542, a bending bottom pin 544 provided at the center position on the outer side of the bending turntable 543, and a bending block 545 provided on the outer side of the bending turntable 543 next to the bending bottom pin 544. The bending turntable 543 drives the bending block 545 to rotate around the bending bottom pin 544, and the end of the bending block 545 near the bending bottom pin 544 is provided with a bending end face 5451.

[0099] While one end of the frame is being processed by the punching and bending mechanism 51, the other end of the frame is being processed by the bending mechanism 54. The working principle of the bending mechanism 54 is as follows:

[0100] The other end of the frame is moved to the underside of the bending bottom pin 544. At this time, the bending block 545 is located under the end of the frame. The bending servo motor 542 starts and drives the bending turntable 543 to rotate. When the bending turntable 543 rotates, it drives the bending block 545 to rotate in the opposite direction around the bending bottom pin 544 as the center point. During the rotation, the bending block 545 uses the bending end face 5451 to press and push the end of the frame to bend, thereby enabling the other end of the frame to be wound.

[0101] In this embodiment, reference Figure 22 As shown, the upper folding mechanism 55 includes an upper folding moving platform 551, on which an upper punching cylinder 552 and a lower punching cylinder 553 are provided. A punching seat 2 is connected to the telescopic shaft of the upper punching cylinder 552 and the lower punching cylinder 553. A guide post 3 554 is provided on the upper folding moving platform 551 that slides linearly with the punching seat 2. The upper punching seat 2 555 is connected to the upper punching die 556, and the lower punching seat 2 557 is connected to the lower punching die 558. The upper punching die 556 and the lower punching die 558 move relative to each other and form a mold cavity 559 that matches the shape of the bent portion of the frame.

[0102] While one end of the frame is being processed by the outward folding mechanism 52, the other end of the frame is being processed by the upward folding mechanism 55. The working principle of the upward folding mechanism 55 is as follows:

[0103] After the other end of the frame is bent, it is then transferred between the upper punch die 556 and the lower punch die 558. Then, the upper punch cylinder 552 and the lower punch cylinder 553 are activated to push the upper punch die 556 and the lower punch die 558 to move relative to each other. At this time, the upper punch die 556 and the lower punch die 558 are aligned vertically, thereby bending the bent portion of the frame (such as...). Figure 23 The P4 mark) is clamped inside the mold cavity 559, and the inclined surface at the bottom of the mold cavity 559 is used to make the bending part bend upward (as shown in the image). Figure 23 (P5 mark).

[0104] refer to Figures 24 to 28 As shown, the frame storage and output mechanism 8 includes a scooter positioning platform 81 and several scooter assemblies 82. The scooter positioning platform 81 is provided with a positioning guide groove 801. Several scooter assemblies 82 slide into the positioning guide groove 801 in sequence, and each scooter assembly 82 is provided with a frame storage rack 83. The scooter positioning platform 81 is also provided with a trolley device 84 that drives two adjacent scooter assemblies 82 to move forward synchronously along the direction of the positioning guide groove 801, and a trolley positioning device 85 that is used to maintain the position of the scooter assembly 82 when the trolley device 84 releases the scooter assembly 82.

[0105] The trolley device 84 includes a discharge rack 841 disposed in a positioning guide groove 801, a receiving plate 842 slidably connected to the discharge rack 841, and a power output unit 843 for driving the receiving plate 842 to slide back and forth. The receiving plate 842 is provided with a front trolley push-out component 86 and a rear trolley pull-in component 87.

[0106] When the structure is in operation, the front push-out component 86 clamps the front flyer component 82 at the loading station of the flyer positioning table 81. At the same time, the rear pull-in component 87 clamps the rear flyer component 82. After the front flyer components 82 fill the frame, the power output unit 843 controls the front push-out component 86 and the rear pull-in component 87 to move forward simultaneously, pushing the front flyer component 82 out of the positioning guide groove 801 while pulling the rear flyer component 82 into the loading station of the flyer positioning table 81. This output method has a compact rhythm and high output efficiency.

[0107] The fly cart assembly 82 includes a fly cart 88 and a fly cart 89. The fly cart 88 includes a frame 881 and directional casters 882 connected to the bottom of the frame 881. The fly cart 89 is detachably attached to the top of the frame 881, and the frame storage rack 83 is connected to the fly cart 89. When the fly cart assembly 82 is pushed out from the fly cart positioning platform 81, the worker can use the directional casters 882 to push the entire batch of molded products on the frame storage rack 83 to other workstations for storage or to the next process. The operation is convenient and the product transfer efficiency is high.

[0108] The top of the frame 881 is provided with several spur fixation seats 883 along the width direction, and each spur fixation seat 883 is provided with a V-shaped groove 884; the spur 89 is provided with a square shaft 891 located in the middle on the left and right sides and a spur connecting shaft 892 located in front of or behind the square shaft 891. The spur 89 is connected to the top of the frame 881 by the square shaft 891 and the spur connecting shaft 892 respectively engaging with the corresponding V-shaped groove 884.

[0109] The cooperation between the baffle square shaft 891 and the fly bar connecting shaft 892 and the V-shaped groove 884 restricts the fly bar 89 from swaying back and forth. The multiple fly bar fixing seats 883 can adjust the front and rear position of the fly bar 89 according to the product situation, making the bending frame equipment more flexible and practical.

[0110] In addition, a flyer baffle 885 is connected to one side of the flyer fixing base 883. The upper part of the flyer baffle 885 is provided with an inlet inclined surface 886. The inlet inclined surface 886 helps the square shaft 891 and the flyer connecting shaft 892 to slide into the V-shaped groove 884, thereby improving assembly efficiency.

[0111] The trolley positioning device 85 includes a front trolley positioning component 85a and a rear trolley positioning component 85b. The front trolley positioning component 85a and the rear trolley positioning component 85b are fixed at a distance from each other on the trolley positioning platform 81. Both the front trolley positioning component 85a and the rear trolley positioning component 85b are equipped with trolley positioning sensors 85c. After the front trolley push-out component 86 and the rear trolley pull-in component 87 complete one round of output, they need to be reversed and reset. At this time, the front trolley push-out component 86 and the rear trolley pull-in component 87 will release the trolley component 82 at the same time. Therefore, during this period, the front trolley positioning component 85a and the rear trolley positioning component 85b are used to position the front and rear trolley components 82 to prevent the trolley components 82 from sliding and shifting, which would affect the subsequent output accuracy.

[0112] Specifically, the power output unit 843 includes a servo motor 8431, a coupling 8432, a lead screw shaft 8433, and a lead screw nut 8434. The output end of the servo motor 8431 is connected to one end of the coupling 8432, the lead screw shaft 8433 is connected to the other end of the coupling 8432, the lead screw nut 8434 is sleeved on the lead screw shaft 8433 and connected to a conveying plate 8435 that slides on the discharge rack 841. The conveying plate 8435 is connected to the receiving plate 842, and the lead screw nut 8434 drives the receiving plate 842 to move under the drive of the lead screw shaft 8433.

[0113] It should be noted that the power output unit 843 can also adopt one of the following methods: gear drive, belt drive, chain drive, or linkage drive.

[0114] The frame storage rack 83 includes a hanging plate 831, which is attached to one side of the flyer 89. The inner side of the hanging plate 831 is provided with several sets of hanging racks along the height direction. Each set of hanging racks includes two parallel hanging arms 832. Multiple one-to-one frame positioning slots 833 are opened on the two hanging arms 832. The frame storage rack 83 with this structure can make full use of the height space of the flyer 88, so that one flyer 88 can store more frames.

[0115] The front vehicle ejection component 86 and the rear vehicle pull-in component 87 have the same structure. Taking the front vehicle ejection component 86 as an example:

[0116] The device includes two trolley cylinders 861 and a baffle seat 862 located in front of the trolley cylinders 861. The telescopic shafts of the two trolley cylinders 861 move outwards and opposite to each other and are fixed with trolley stop heads 863. Two trolley stops 864 are engaged on the trolley stop heads 863, forming a movable clamping space between the two trolley stops 864 for clamping the fly bike assembly 82. The baffle seat 862 is provided with an inner guide sliding hole 865 adapted to the two trolley stops. The two trolley stops 864 can restrict the forward and backward movement of the fly bike assembly 82. In addition, when the front carriage push-out assembly 86 and the rear carriage pull-in assembly 87 release the fly bike assembly 82 and reset it, the trolley cylinders 861 drive the trolley stops 864 to retract into the inner guide sliding hole 865 to avoid collision between the trolley stops 864 and the fly bike assembly 82.

[0117] The front vehicle positioning assembly 85a and the rear vehicle positioning assembly 85b have the same structure, both including a stop seat 851 and a cylinder bracket 852 connected to the stop seat 851. The cylinder bracket 852 is equipped with a material-stopping cylinder 853. A positioning block head 854 is fixed on the telescopic shaft of the material-stopping cylinder 853. Two positioning blocks 855 are engaged on the positioning block head 854. The two positioning blocks 855 form a fixed clamping space for clamping the frame 881. The stop seat 851 is provided with guide sliding holes 856 adapted to the two blocks. Similarly, the two positioning blocks 855 can restrict the forward and backward movement of the flying car assembly 82.

[0118] The scooter positioning platform 81 includes a floor 811 and scooter positioning seats 812 connected to both sides of the floor 811. A positioning guide groove 801 is defined between the two scooter positioning seats 812. The scooter positioning platform 81 with this structure is installed on the ground. It has a simple structure and does not occupy height space, so that a taller scooter component 82 can be used, increasing the storage capacity of the frame.

[0119] refer to Figure 29 and Figure 30 As shown, the workpiece handling mechanism 7 includes a handling moving platform 71 arranged along the workpiece conveying direction. The handling moving platform 71 is sequentially provided with a bending frame handling device 72 for moving the bending frame (marked with "N" in the figure) to the discharge end of the horizontal unloading mechanism 3, a first welding handling device 73 for moving the bending frame or semi-finished product (marked with "H" in the figure) from the upper welding mechanism 4 to the lower welding mechanism 4, a second welding handling device 74 for moving the semi-finished product to the tail hook forming mechanism assembly 5, and a third welding handling device 75 for moving the finished frame to the discharge stacking mechanism 6.

[0120] The curved frame transport device 72 includes a transport base plate 721 and a transport motor 722 that drives the transport base plate 721 to slide along the transport moving platform 71. A transport base 723 is fixed on the transport base plate 721. A pair of rearward extending clamping arms 724 are rotatably hinged to the transport base 723. A clamping arm cylinder 725 is hinged between the clamping arms 724 and the transport base 723. A curved frame clamping hand 726 is provided at the outer end of the clamping arms 724. The curved frame is clamped away from the curved frame workbench 22 by the curved frame clamping hand 726.

[0121] The structures of the first welding transport device 73, the second welding transport device 74, and the third welding transport device 75 are roughly the same as those of the curved frame transport device 72. The difference is that a gripper seat 727 is slidably connected on the transport base 723, and a gripper cylinder 728 is provided on the transport base plate 721 to control the up and down movement of the gripper seat 727. A vertically positioned workpiece gripper 729 is provided on the gripper seat 727.

A palletizing robot 65 is provided on the swing end of the swing arm 62. The palletizing robot 65 uses the swing arm 62 to transfer materials, and while completing the position transfer, it can also stand up the flat frame product, making it convenient to hang the frame product on the frame storage rack 83.

[0123] In addition, a finished product pressure plate 66 is connected to one side of the palletizing robot 65. When the palletizing robot 65 picks up the finished frame, the finished product pressure plate 66 limits one side of the finished frame to prevent it from tilting up.

[0124] In this embodiment, the translational motion device 64 includes a traveling seat 641, which is slidably connected to the palletizing support seat 61 via a transverse drive assembly 642. A lifting plate 643 is slidably connected to the traveling seat 641 via a longitudinal drive assembly 644. The rotary motor 63 is fixedly connected to the bottom end of the lifting plate 643. The transverse drive assembly 642 and the longitudinal drive assembly 644 are composed of a fixed slide rail, a movable slider, a rack and pinion, and a motor.

[0126] During welding, the welding mechanism 4 first positions the bent frame part on the welding station using the lower electrode 43 and the side positioning guide rod 48. Then, the short horizontal line is positioned at the interval position of the bent frame by the cooperation of the line fixing plate 47 and the horizontal lower positioning block 410. Finally, the upper electrode 45 and the lower electrode 43 clamp the short horizontal line and the bent frame, and welding is achieved after high voltage is applied.

The bottom baffle 562 is located below the wire-pressing cylinder head 564, and its top surface is provided with a side stop block 565. The side stop block 565 is recessed with an avoidance recess 5651 corresponding to the wire-pressing cylinder head 564. The side stop block 565 can achieve lateral positioning of the frame, so that the tail end of the frame can be aligned with the above-mentioned mechanisms.

[0131] Any mobile platform includes welding mobile platform 41 (e.g.) Figure 31 As shown), the bending moving platform 511 (as shown) Figure 16 As shown), the outward-folding mobile platform 521 (as shown) Figure 17 As shown), the flattened mobile platform 531 (as shown) Figure 19 As shown), bending moving platform 541 (as shown) Figure 21 (as shown) and the folding mobile platform 551 (as shown) Figure 22 (as shown)
