[0031] Figures 1-4 As shown in the figure, the two groups of extension frames 3 are respectively located on both sides of the rotating frame, and both groups of extension frames 3 are slidingly connected to the rotating frame 2, so that in use, the two groups of extension frames 3 can be respectively pulled out to both sides according to the width of the iron plate, thereby increasing the width of the extension frame 3, the air cylinder 4 has two groups and is arranged inside the support frame 1, and the two groups of air cylinders 4 are respectively close to both sides of the support frame 1, the rotating assembly 6 is located at the middle position of the two groups of air cylinders 4, and the fixed end and the output end of the two groups of air cylinders 4 are respectively hinged to the rotating frame 2 and the support frame 1.

[0032] As shown in the figure, the two groups of extension frames 3 are respectively located on both sides of the rotating frame, and both groups of extension frames 3 are slidingly connected to the rotating frame 2, so that in use, the two groups of extension frames 3 can be respectively pulled out to both sides according to the width of the iron plate, thereby increasing the width of the extension frame 3, the air cylinder 4 has two groups and is arranged inside the support frame 1, and the two groups of air cylinders 4 are respectively close to both sides of the support frame 1, the rotating assembly 6 is located at the middle position of the two groups of air cylinders 4, and the fixed end and the output end of the two groups of air cylinders 4 are respectively hinged to the rotating frame 2 and the support frame 1. Figures 1-4 ​As shown in the drawings, one end of the rotating frame 2 is hinged to the support frame 1, and the other end of the rotating frame 2 is provided with two groups of bolts 21, which are both threadedly connected to the rotating frame 2 and arranged on the two sides of the rotating frame 2. A plurality of corresponding grooves are arranged on the two groups of extension frames 3 at the positions of the bolts 21. Therefore, after the extension frames 3 are moved to the desired positions, the bolts 21 can be screwed in the forward direction, and the positions of the extension frames 3 can be limited after the end portions of the bolts 21 are inserted into the grooves, thereby avoiding the continuous movement of the extension frames 3.

[0033] As shown in the drawings, Figure 5 The ball assembly 5 includes a base 51 and balls 52. The base 51 is fixedly connected to the rotating frame 2 and the extension frames 3 by screws. The top end of the base 51 is provided with a groove, and the balls 52 are embedded in the groove at the top end of the base 51. Therefore, the balls 52 can rotate while being prevented from falling out of the base 51. When the iron plate is placed on the rotating frame 2, the balls 52 will directly contact the iron plate. Therefore, the balls 52 can support the weight of the iron plate while rotating with the movement of the iron plate, thereby reducing the friction caused by the iron plate.

[0034] As shown in the drawings, Figures 6-7 The rotating assembly 6 includes a housing 61, a rotating plate 62, second magnets 63, a collector ring 64, brushes 65, a relay 66, and a control circuit board 67. The housing 61 is arranged at the center of the rotating frame 2 and is welded to the rotating frame 2. The rotating plate 62 is vertically arranged inside the housing 61. The bottom end of the rotating plate 62 is clamped to the housing 61, and a plurality of steel balls are embedded in the bottom end of the rotating plate 62. Therefore, when the rotating plate 62 rotates, the steel balls can reduce the friction between the rotating plate and the housing 61, thereby ensuring that the rotating plate 62 is rotatably connected to the bottom plate of the housing 61. A group of servo motors 8 is arranged below the housing 61. The servo motors 8 are fixedly connected to the housing 61 by screws, and the output ends of the servo motors 8 pass through the bottom plate of the housing 61 and are connected to the rotating plate 62.

[0035] As shown in the drawings, Figures 6-7 Therefore, the servo motors 8 can drive the rotating plate 62 to rotate after being started. The second magnets 63 are fixedly connected to the rotating plate 62 by screws. Therefore, the rotating plate 62 can drive the four groups of second magnets 63 to synchronously rotate when the rotating plate 62 rotates. The four groups of second magnets 63 are arranged at the four positions around the rotating plate 62, thereby increasing the adsorption area of the second magnets 63 and the stability of the adsorption of the second magnets 63. The first magnets 7 and the second magnets 63 are both electromagnets.

[0036] As shown in the drawings, Figures 6-7As shown, the magnetism of the electromagnet can be controlled by energizing or de-energizing, so when the worker places or takes the iron plate, as long as the first magnet 7 and the second magnet 63 are de-energized, the first magnet 7 and the second magnet 63 will not hinder the worker's process of taking the iron plate, and when the first magnet 7 and the second magnet 63 are energized, the first magnet 7 and the second magnet 63 can immediately generate magnetism to adsorb the iron plate, thereby limiting the position of the iron plate.

[0037] As shown, Figures 6-7 The four groups of second magnets 63 are electrically connected with the collector ring 64, the collector ring 64 is sleeved below the rotating plate 62 and is bonded to the rotating plate 62, so that the rotating plate 62 drives the collector ring 64 to rotate when rotating, the collector ring 64 is made of conductive material (such as copper or aluminum), the brush 65 is arranged on one side of the collector ring 64 and is connected to the bottom plate of the shell 61, and the brush 65 is in contact with the collector ring 64, so that the brush 65 directly inputs external current into the inside of the collector ring 64, and then transmits the current to the second magnets 63 through the collector ring 64.

[0038] As shown, Figures 6-7 Because the collector ring 64 is always in contact with the brush 65, even when the collector ring 64 rotates with the rotating plate 62, the brush 65 always transmits current into the inside of the collector ring 64, thereby avoiding causing the second magnets 63 to be de-energized, the control circuit board 67 is connected to the other side of the collector ring 64 and is electrically connected with the relay 66, the relay 66 is located at the middle position between the brush 65 and the control circuit board 67 and is connected to the bottom plate of the shell 61, and the relay 66 is electrically connected with the first magnet 7 and the brush 65.

[0039] As shown, Figures 6-7 Therefore, the control circuit board 67 can start or stop the first magnet 7 by controlling the relay 66, and the control circuit board 67 can also control the brush 65 to be energized or de-energized through the relay 66, so as to turn on or turn off the electromagnet, the servo motor 8 is electrically connected with the control circuit board 67, so the worker can directly start or stop the servo motor 8 through the control circuit board 67.

[0040] The movement process of the embodiment: after the support frame 1 is moved to the desired position by the universal wheel 11, the position of the extension frame 3 can be moved according to the size of the iron plate to be bent, after the extension frame 3 is moved to the desired position, the bolt 21 is screwed in the positive direction until the end of the bolt 21 is inserted into the pre-designed groove at the end of the extension piece, and then the iron plate is placed on the rotating frame 2 and the end of the iron plate to be bent is moved to the bending position of the bending machine.

[0041] Subsequently, the first magnet 7 and the second magnet 63 are started by the control circuit board 67, after the first magnet 7 and the second magnet 63 completely adsorb the iron plate, the bending machine can be opened to bend the end of the iron plate, during the working of the bending machine, the end of the iron plate is bent into the required shape, but the whole iron plate is rotated upward during the bending of the end of the iron plate by the bending machine, so when the iron plate is bent by the bending machine, the cylinder 4 is opened, the output end of the cylinder 4 can be used to lift the rotating frame 2 and the iron plate upward with the hinge point as the center, during the upward rotation of the rotating frame 2, the whole iron plate is lifted, so as to cooperate with the bending machine to bend.

[0042] During the bending of the bending machine and the release of the end of the iron plate, the cylinder 4 is opened again and the output end of the cylinder 4 is retracted, during the retraction of the output end of the cylinder 4, the rotating frame 2 is rotated downward, and during the downward rotation of the rotating frame 2, the whole iron plate is supported, so as to avoid the sudden falling of the iron plate, after the rotating frame 2 is reset to the original position, the first magnet 7 is closed and the servo motor 8 is opened.

[0043] The servo motor 8 can be used to rotate the iron plate by the rotating plate 62 and the second magnet 63 after starting, after the end of the iron plate which is not bent is rotated to the position of the bending machine, the servo motor 8 is closed, then the second magnet 63 is closed and the end of the iron plate which is not bent is moved to the bending position of the bending machine, then the first magnet 7 and the second magnet 63 are started again, after the first magnet 7 and the second magnet 63 adsorb the iron plate, the above bending process can be repeated, after the four ends of the iron plate are all bent, the first magnet 7 and the second magnet 63 are closed and the iron plate which has been bent is taken off from the rotating frame 2.

[0044] The above embodiment is only for illustrating the technical idea of the present application, and cannot limit the protection scope of the present application, any modification made on the basis of the technical scheme according to the technical idea of the present application falls within the protection scope of the present application.
