TECHNICAL FIELD
[0001] The application belongs to the technical field of metal, and particularly relates to a metal piece bending device. BACKGROUND
[0002] At present, when low-carbon steel metal plates are bent, an operator usually manually places the plate on a V-shaped die and repeatedly adjusts the position of the plate to accurately align the metal plate with the die profile. However, due to the dependence on manual positioning, the adjustment accuracy is low, resulting in obvious deviation of the bending positions of the multiple V-shaped workpieces formed by bending, poor consistency of the finished products, and difficulty in meeting the use requirements. In addition, after bending is completed, the V-shaped plate still needs to be manually taken out of the die. Due to the rebound effect, the workpiece generates a holding force with the surface of the die, and micro-warping deformation may occur. The workpiece can be separated and taken out of the die cavity only by the operator with the help of a tool by prying or knocking. The operation is complicated and inefficient.

[0015] Compared with the prior art, the metal bending device provided by the present invention has at least the following beneficial effects: (1) The low-carbon steel metal plate can be bent into a V-shaped structure by means of the hydraulic cylinder, V-shaped mold and V-shaped press; the bent V-shaped plate can be automatically pushed out by means of the first electric push rod and triangular push plate; the initial position of the low-carbon steel metal plate can be positioned by means of the C-shaped frame, which ensures that the bending of the low-carbon steel metal plate is uniform, thereby avoiding obvious deviations in the bending position of multiple V-shaped plates formed by bending, resulting in poor product consistency. At the same time, the bent V-shaped plate can be automatically pushed out, which is simple to operate and improves the efficiency of V-shaped plate removal.
[0016] (2) The toothed ring, the first gear, and the first servo motor enable the rotating ring to rotate, thereby driving the bent V-shaped plate on the built-in V-shaped placement block to rotate; the built-in magnet allows the V-shaped plate to be attracted into the built-in V-shaped placement block, preventing the V-shaped plate from falling off when rotating with the ring; the contact block allows the contact rod to be pushed down when the rotating ring rotates, thereby pushing the push column down and entering the opening to push the V-shaped plate to move, separating the V-shaped plate from the built-in magnet and causing the V-shaped plate to fall onto the triangular strip. This design allows the V-shaped plate to automatically separate from the built-in magnet and fall onto the triangular strip after adjusting its position; the connecting pipe, the first piston, the second piston, the elastic plate, the first moving rod, and the second moving rod allow the push rod to pass over the elastic plate under the blocking action of the second blocking block when moving, and then push the elastic plate to move during the push rod reset process, thereby moving the second moving rod, and pushing the ore in the connecting pipe through the second piston. The hydraulic oil moves the material, eventually causing the triangular bar to move out of the rotating ring and into the placement box. This design allows the V-shaped plates to be transported into the placement box. A second electric push rod, a second outer shell, and a T-shaped column allow the V-shaped plates on the T-shaped column to move downwards, thus driving the V-shaped plates entering the placement box one by one. A second servo motor allows the placement box to rotate to a horizontal position. A third electric push rod allows the T-shaped column to release its restriction on the V-shaped plates. A moving column blocks the V-shaped plates below the arc-shaped opening inside the placement box. A third servo motor, a second gear, a rack, an arc-shaped column, an arc-shaped hole, and a moving column connect the moving column to the arc-shaped column, thereby pushing several V-shaped plates inside the placement box to achieve unloading and storage. This streamlined operation from initial loading and unloading to orderly storage effectively avoids the inefficiency and high labor intensity of traditional manual transfer of V-shaped plates, significantly improving the efficiency of the storage process and the continuity of overall production.

[0022] Please see Figures 1-21 The present invention provides a metal bending device, including a placement platform 100, a V-shaped mold 102 fixed on the top surface of the placement platform 100, C-shaped frames 103 fixed on both sides of the top surface of the V-shaped mold 102, a C-shaped frame 101 fixed on the top surface of the placement platform 100, a hydraulic cylinder 104 fixed on the bottom surface of the inner side wall of the C-shaped frame 101, a V-shaped press 105 fixed at the output end of the hydraulic cylinder 104, a first T-shaped rod 106 fixed on the top surface of the placement platform 100, a first electric push rod 107 fixed on the top surface of the first T-shaped rod 106, and a triangular push plate 108 fixed at the output end of the first electric push rod 107.
[0023] As a further embodiment of the present invention, two support frames 201 are fixed on one side of the top surface of the placement platform 100, and a rotating ring 200 is provided between the two support frames 201. Two engaging rings 202 are fixed on the outer wall of the rotating ring 200, and the engaging rings 202 are correspondingly and movably engaged inside the support frame 201. A toothed ring 203 is fixed on the outer wall of the rotating ring 201. A first servo motor 205 is fixed at the bottom of one side of the support frame 201. A first gear 204 is fixed at the output end of the first servo motor 205. The first gear 204 meshes with the toothed ring 203. An internal V-shaped placement block 206 is fixed on the inner wall of the rotating ring 200. Two placement slots 207 are respectively opened on both sides of the internal V-shaped placement block 206, and an internal magnet 208 is fixed in the placement slot 207.
[0024] The toothed ring 203, the first gear 204, and the first servo motor 205 enable the rotating ring 200 to rotate, thereby driving the bent V-shaped plate on the built-in V-shaped placement block 206 to rotate; the built-in magnet 208 enables the V-shaped plate to be attracted into the built-in V-shaped placement block 206, preventing the V-shaped plate from falling off when it rotates with the rotating ring 200.
[0025] As a further embodiment of the present invention, a C-shaped rod 218 is fixed to one side of the C-shaped frame 101, a first outer shell 212 is fixed to the bottom surface of the C-shaped rod 218, an inner block 213 is movably engaged inside the first outer shell 212, a push column 214 is fixed to the bottom surface of the inner block 213, a second L-shaped rod 215 is fixed to the bottom of the outer side wall of the push column 214, a contact rod 216 is fixed to the top of one side of the second L-shaped rod 215, a first spring 217 is sleeved at the bottom of the push column 214, the bottom end of the first spring 217 is fixed to the top surface of the second L-shaped rod 215, and the top end of the first spring 217 is fixed to the bottom surface of the first outer shell 212. An opening 209 is opened on the outer side wall of the rotating ring 200, a first L-shaped rod 210 is fixed to the outer side wall of the rotating ring 200, a contact block 211 is fixed to one end of the first L-shaped rod 210, and the contact block 211 cooperates with the contact rod 216.
[0026] By using the contact block 211, when the rotating ring 200 rotates, the contact block 211 contacts the contact rod 216, which pushes the contact rod 216 downward, thereby causing the push column 214 to move downward and enter the opening 209 to push the V-shaped plate to move. This causes the V-shaped plate to separate from the built-in magnet 208, and the V-shaped plate to fall onto the triangular bar 300. This design allows the V-shaped plate to automatically separate from the built-in magnet 208 and fall onto the triangular bar 300 after its position is adjusted, making it easier for the triangular bar 300 to drive the V-shaped plate to move subsequently.
[0027] As a further embodiment of the present invention, two fixing rods 315 are fixed to one side of the V-shaped mold 102. A connecting pipe 302 is fixed to one end of each fixing rod 315. A first moving rod 303 is movably connected to one end of the connecting pipe 302. A first piston 304 is fixed to one end of the first moving rod 303 and is located inside the connecting pipe 302.

A first blocking block 313 and a second blocking block 314 are fixed to the top surface of the placement platform 107.

[0028] Through the connecting pipe 302, the first piston 304, the second piston 305, the elastic plate 311, the first moving rod 303, and the second moving rod 306, the push rod 312 can pass over the elastic plate 311 under the blocking action of the second blocking block 314 when it moves. Then, during the reset process of the push rod 312, it can push the elastic plate 311 to move, thereby causing the second moving rod 306 to move. The second piston 305 pushes the mineral oil-type hydraulic oil in the connecting pipe 302 to move, and finally causes the triangular bar 300 to move out of the rotating ring 200.
[0029] As a further embodiment of the present invention, a V-shaped passage plate 316 is fixed on the side of the V-shaped mold 102 away from the first electric push rod 107, and one end of the V-shaped passage plate 316 is in contact with one side of the built-in V-shaped placement block 206.
[0030] The V-shaped passage plate 316 allows the bent V-shaped plate on the V-shaped mold 102 to pass through the V-shaped passage plate 316 and enter the built-in V-shaped placement block 206.
[0031] As a further embodiment of the present invention, a stabilizing frame 402 is fixed to one side of the placement platform 100, and a second servo motor 403 is fixed to one side of the stabilizing frame 402. The output end of the second servo motor 403 passes through the stabilizing frame 402, and an L-shaped plate 401 is fixed to the output end of the second servo motor 403. A placement box 400 is fixed to one side of the L-shaped plate 401. A first side opening 404 is opened on the side of the placement box 400 away from the placement platform 100. A second electric actuator 405 is fixed to the side of the placement box 400 away from the placement platform 100, and a second connecting rod 406 is fixed to the output end of the second electric actuator 405.

A third moving rod 412 is fixed to one end of the T-shaped column 410. The third moving rod 412 moves through the second outer shell 409. One end of the second connecting rod 406 is fixed to the outer wall of the second outer shell 409. A third electric push rod 407 is fixed to the bottom of the side of the placement box 400 away from the placement platform 100. The third electric push rod 407 cooperates with the third moving rod 412.
[0032] The second electric push rod 405 and the second connecting rod 406 enable the second outer shell 409 to move, thereby enabling the T-shaped column 410 to move. The movement of the T-shaped column 410 drives the V-shaped plate on the T-shaped column 410 to move, thus enabling the V-shaped plate to be unloaded into the placement box 400. The third electric push rod 407 and the third moving rod 412 enable the placement box 400 to be in a horizontal state, and the T-shaped column 410 to be moved to the corresponding position. The third electric push rod 407 is activated to push the third moving rod 412 to move, thereby enabling the T-shaped column 410 to move and removing the T-shaped column 410 from limiting the V-shaped plate inside the placement box 400.
[0033] As a further embodiment of the present invention, an inner plate 417 is fixed inside the placement box 400. A fourth side opening 418 is opened on the top of one side of the inner plate 417, and a fifth side opening 419 is opened on one side of the inner plate 417.

A side strip 413 is fixed on the top of one side of the placement box 400 near the placement platform 100. An arc-shaped opening 414 is opened on one side of the placement box 400 near the placement platform 100.
[0034] The second side opening 415 allows the V-shaped plate to enter the placement box 400; the fourth side opening 418 allows the triangular strip 300 to pass through, while the V-shaped plate on the triangular strip 300 will not pass through the fourth side opening 418, thus blocking the V-shaped plate and causing it to fall off the triangular strip 300 onto the T-shaped post 410; the third side opening 416 allows the moving post 505 to pass through and push the placement box 400. Several V-shaped plates inside the storage box 602 move and enter the storage box 602. Through the arc-shaped opening 414, when the storage box 400 rotates at a certain angle, the moving column 505 can enter the arc-shaped opening 414 and eventually contact the inner wall of the third side opening 416. At this time, the side strip 413 contacts the guide column 503, so that when the storage box 400 rotates, it can drive the guide column 503 and the moving column 505 to rotate. When the moving column 505 rotates with the storage box 400, it can block the V-shaped plates inside the storage box 400 to prevent the position of the V-shaped plates from changing.
[0035] As a further embodiment of the present invention, an arc-shaped groove 500 is formed on one side of the placement platform 100. An arc-shaped rod 501 is fixed between the two sides inside the arc-shaped groove 500. A movable block 502 is movably connected to the outer wall of the arc-shaped rod 501. The movable block 502 is movably engaged with the arc-shaped groove 500. A fourth spring 508 is provided on the outer wall of the arc-shaped rod 501. One end of the fourth spring 508 is fixed to one side of the movable block 502, and the other end of the fourth spring 508 is fixed to one side inside the arc-shaped groove 500. A guide post 503 is fixed to the other side of the movable block 502. A first magnet 504 is fixed to one side of the inner wall of the guide post 503. A magnet 504 is engaged inside the guide post 503. A movable column 505 is provided, and a second magnet 506 is fixed to the outer wall of the movable column 505 near the guide column 503. Two arc-shaped holes 507 are provided on the outer wall of the movable column 505. A second T-shaped rod 511 is fixed to one side of the placement platform 100. A rack 512 is movably engaged on the second T-shaped rod 511. A top block 513 is fixed to one side of the top surface of the rack 512. Two arc-shaped columns 514 that cooperate with the arc-shaped holes 507 are fixed to the top surface of the top block 513. A third servo motor 509 is fixed to one side of the inner wall of the placement platform 100. A second gear 510 is fixed to the output end of the third servo motor 509. The second gear 510 meshes with the rack 512.
[0036] The arc-shaped rod 501 allows the position of the moving block 502 to be movably limited. The fourth spring 508 allows the moving block 502 to be stretched when it rotates, facilitating its subsequent reset. The second gear 510 and the third servo motor 509 allow the rack 512 to move. The arc-shaped column 514 allows the arc-shaped hole 507 and the arc-shaped column 514 to connect, facilitating the separation of the moving column 505 from the guide column 503. This allows the movement of the moving column 505 to push several V-shaped plates within the placement box 400.
[0037] As a further embodiment of the present invention, a placement plate 600 is fixed to one side of the placement platform 100, and two baffles 601 are fixed to the top surface of the placement plate 600. A positioning post 605 is fixed to one end of the two baffles 601 away from the placement box 400, and a blocking plate 607 is fixed to one end of the two positioning posts 605. A contact strip 604 is movably connected between the two positioning posts 605. A fifth spring 606 is provided around the positioning posts 605. A storage box 602 is provided between the two baffles 601, and a sixth side opening 603 is provided on one side of the storage box 602.
[0038] The storage box 602 can be limited by the stop bar 601. The contact bar 604 and the fifth spring 606 allow the storage box 400 to be moved by pulling the contact bar 604 when it is in a horizontal state. This places the storage box 602 between the two stop bars 601, so that one end of the storage box 602 can fit against one end of the horizontal storage box 400. Then, the contact bar 604 is released, so that the storage box 602 fits tightly against the storage box 400. This design avoids the existence of space between the contact surfaces of the storage box 602 and the storage box 400, which would affect the entry of the V-shaped plate into the storage box 602.
[0039] As a further embodiment of the present invention, a PLC controller 700 is fixed on the top surface of the placement platform 100, and the hydraulic cylinder 104, the first electric push rod 107, the first servo motor 205, the second servo motor 403, the second electric push rod 405, the third electric push rod 407 and the third servo motor 509 are respectively electrically connected to the PLC controller 700.
[0040] The entire device can be coordinated and controlled by the configured PLC controller 700.
[0041] Among them, the centers of the arc-shaped groove 500, arc-shaped rod 501, arc-shaped hole 507 and arc-shaped opening 414 all coincide with the axis of the output end of the second servo motor 403, and the radii corresponding to the centers are all the same; when the arc-shaped column 514 is in the initial position, its center coincides with the axis of the output end of the second servo motor 403, and the radius corresponding to its center is the same as the radius of the center of the arc-shaped groove 500, arc-shaped rod 501, arc-shaped hole 507 and arc-shaped opening 414.
[0042] In summary: When bending low-carbon steel sheet, firstly, a sheet of the appropriate size is placed on the surface of the V-shaped mold 102. At this time, the C-shaped frames 103 on both sides limit the sheet. Then, the PLC controller 700 starts the hydraulic cylinder 104, which drives the V-shaped press 105 downward. The V-shaped press 105 presses and bends the sheet, bending it into a V-shape to form a V-shaped sheet. The V-shaped sheet is located within the V-shaped structure of the V-shaped mold 102. Then, the output end of the hydraulic cylinder 104 drives the V-shaped press 105 upward. Subsequently, the PLC controller 700 controls the first electric push rod 107 to start, which pushes the triangular push rod. As plate 108 moves, the triangular pusher 108 moves, pushing the V-shaped plate to move, causing the V-shaped plate to pass through the V-shaped passage plate 316 and enter the built-in V-shaped placement block 206. The V-shaped plate is attracted and fixed by the built-in magnet 208. During this process, the push rod 312 moves. When the bottom end of the push rod 312 contacts the elastic plate 311, due to the obstruction of the second blocking block 314, the bottom end of the push rod 312 pushes the elastic plate 311 to deform and pass over the elastic plate 311. After the bottom end of the push rod 312 passes over the elastic plate 311, part of the V-shaped plate is now located on the V-shaped passage plate 316, and the other part is located on the built-in V-shaped placement block 206. As the triangular pusher 108 continues to move... Continuing to move, the V-shaped plate is fully pushed onto the built-in V-shaped placement block 206. At this time, the push rod 312 is located below the triangular bar 300. Subsequently, the PLC controller 700 controls the output end of the first electric push rod 107 to move in the reverse direction until the push rod 312 is no longer located below the triangular bar 300. The first electric push rod 107 stops working. Then, the PLC controller 700 controls the first servo motor 205 to start. The rotation of the first servo motor 205 drives the first gear 204 to rotate. Through the cooperation with the toothed ring 203, the rotating ring 200 rotates. The rotation of the rotating ring 200 drives the contact block 211 to rotate. When the contact block 211 contacts the contact rod 216, the contact block 211 rotates. Under the action of 11, the contact rod 216 slowly moves down, and the downward movement of the contact rod 216 drives the push column 214 to move down. The push column 214 gradually enters the opening 209. When the contact rod 216 moves to the bottom of the contact block 211, the push column 214 pushes the V-shaped plate, causing the V-shaped plate to separate from the built-in magnet 208. At this time, the V-shaped plate falls onto the triangular strip 300, forming an inverted V state. Then the rotating ring 200 continues to rotate, causing the contact block 211 to separate from the contact rod 216. The first spring 217 pulls the push column 214 to reset. Then the rotating ring 200 rotates to reset the built-in V-shaped placement block 206. After that, the first servo motor 205 stops rotating.Then, the PLC controller 700 controls the output of the first electric actuator 107 to start in reverse again, causing the push rod 312 to move in reverse. When the bottom of the push rod 312 contacts the elastic plate 311, the push rod 312 continues to push the elastic plate 311 to move. The movement of the elastic plate 311 drives the second moving rod 306 to move. The movement of the second moving rod 306 drives the second piston 305 to push the mineral oil-type hydraulic oil in the connecting pipe 302, thereby pushing the first piston 304. The movement of the first piston 304 drives the first moving rod 303 and the first connecting rod 301 to move. The movement of the first connecting rod 301 drives the triangular bar 300 to move. The movement of the triangular bar 300 drives the V-shaped plate on it to move. During this process, the second spring 308 is gradually compressed. When the V-shaped plate enters the outlet through the second side port 415... After being placed in the box 400, the triangular strip 300 continues to move, passing through the fourth side opening 418 and the first side opening 404, until it is removed from the box 400. During this process, the V-shaped plate cannot pass through the fourth side opening 418 and is blocked by the inner plate 417. When the triangular strip 300 is removed from the box 400, the V-shaped plate falls onto the T-shaped post 410, while the L-shaped strip 310 is blocked by the first blocking block 313. Subsequently, the push rod 312 passes over the elastic plate 311 and moves to its initial position. The compressed second spring 308 pushes the fixing ring 307, causing the second moving rod 306 to move. Through the cooperation of the first piston 304, the second piston 305, and the mineral oil-based hydraulic oil, the triangular strip 300 moves and resets, thus completing the bending and transportation of a V-shaped plate. The same steps are then repeated for the operation of the metal plate.
[0043] When the V-shaped plate is positioned on the T-shaped column 410, the PLC controller 700 activates the second electric push rod 405. The second electric push rod 405 pushes the second connecting rod 406 to move, which in turn moves the second housing 409, causing the T-shaped column 410 to move downwards. At this time, the V-shaped plate on the T-shaped column 410 also moves downwards, leaving space for the next V-shaped plate. When the next V-shaped plate falls onto the previous V-shaped plate in the placement box 400, the second electric push rod 405 activates again, causing the T-shaped column 410 to move downwards again, again leaving space for the next V-shaped plate. This process repeats, resulting in several V-shaped plates being stacked in an orderly manner within the placement box 400. At this time, the T-shaped column 410 is located at the bottom of the placement box 400, the third electric push rod 407 corresponds to the third moving rod 412, and the topmost V-shaped plate is located below the arc-shaped opening 414. At this time, the PLC controller 700 does not activate the hydraulic cylinder 104. Subsequently, the PLC controller 700 controls the second servo motor 403 to rotate. The rotation of the second servo motor 403 drives the placement box 400 to rotate slowly. When the moving column 505 passes through the arc-shaped opening 414, the moving column 505 contacts the inner wall of the third side opening 416, and the guide column 503 contacts the side strip 413, so that the V-shaped plate below the arc-shaped opening 414 is blocked. As the placement box 400 rotates, the guide column 503 and the side strip 413 rotate synchronously, so that the moving block 502 moves. At this time, the fourth spring 508 is stretched until the placement box 400 is in a horizontal state. At this time, the arc-shaped column 514 is located in the arc-shaped hole 507, and the opening on the guide column 503 is in a horizontal state. Then, the contact strip 604 is pulled, and then the storage box 602 is placed between the two stop strips 601. The pull on the contact strip 604 is released. At this time, the storage box 602 and the placement box 400 are in close contact, and the storage box 602 is positioned. Subsequently, the PLC controller 700 controls the third electric actuator 407 to start, which pushes the third moving rod 412 to move. The movement of the third moving rod 412 drives the T-shaped column 410 to move, causing the T-shaped column 410 to move into the second housing 409. At this time, the V-shaped plate near the storage box 602 is de-positioned, and the T-shaped column 410 no longer obstructs the V-shaped plate. Then, the PLC controller 700 controls the third servo motor 509 to rotate, which drives the second gear 510 to rotate. The rotation of the second gear 510 drives the rack 512 to move, the movement of the rack 512 drives the arc-shaped column 514 to move, and the movement of the arc-shaped column 514 drives the moving column 505 to move, causing the first magnet 504 and the second magnet 506 to separate. The moving column 505 moves out of the guide column 503, and then the moving column 505 moves in the third side opening 416 and pushes the V-shaped plate to move, so that several V-shaped plates in the placement box 400 are pushed into the storage box 602. Then the storage box 602 can be taken out and placed in the corresponding position.Subsequently, the third servo motor 509 of the PLC controller 700 rotates in the reverse direction, causing the moving column 505 to re-engage within the guide column 503. At this time, the first magnet 504 and the second magnet 506 attract each other, connecting the moving column 505 and the guide column 503. Then, the PLC controller 700 controls the second servo motor 403 to rotate in the reverse direction, causing the placement box 400 to rotate in the reverse direction. At this time, the arc-shaped column 514 and the arc-shaped hole 507 separate. During the rotation of the placement box 400, the fourth spring 508 pulls the moving block 502 to move until the moving block 502 is in its initial state. Then, the placement box 400 rotates to its initial state. Subsequently, the PLC controller 700 controls the third electric push rod 407 to move in the reverse direction, and the third spring 411 pushes the T-shaped column 410 to reset. Afterward, the PLC controller 700 controls the second electric push rod 405 to move in the reverse direction, causing the second outer shell 409 to return to its initial position, completing one unloading and storage of several V-shaped plates.
[0044] Figure 5 As shown, there is a space between the bottom surface of the triangular strip 300 and the top surface of the triangular push plate 108, that is, when the triangular push plate 108 is below the triangular strip 300, the top surface of the triangular push plate 108 does not contact the bottom surface of the triangular strip 300; the height of the first connecting rod 301 is higher than the top surface of the placement box 400.
