Description

Technical Field

[0001] The invention belongs to the technical field of three-phase copper busbar production, in particular to a production method of a three-phase copper busbar. Background Art

[0002] In motors, three-phase copper busbars are mainly used at the input and output ends of the motor as conductors for power transmission and distribution.

[0003] In the prior art, a three-phase copper busbar is usually made of a copper plate. The copper plate is crimped with pure copper to form a wide and flat conductor, and is formed through a painting process. When making a three-phase copper busbar, the copper plate is conveyed to a straightening device through a conveying device, so that the copper plate passing through the straightening device is straightened, and is conveyed to a punching machine through a conveying device. After punching, circular holes are formed on the surface of the copper plate. The stamped copper plate is then conveyed to a bending and cutting machine through a conveying device, and then bent and cut after bending to form a copper busbar. A plastic shell is then put on the surface of the copper busbar and heat-sealed to fit the plastic shell with part of the surface of the copper busbar.

[0004] After the copper plate is stamped, there are burrs on the inner wall of the stamped circular holes. Since the stamped three-phase copper busbar is often used as a connecting structure with other electronic components, when the wires of other electronic components pass through the holes of the three-phase copper busbar, the burrs on the inner wall of the hole will contact the wires of other electronic components, resulting in a reduction in the contact area between the wires of other electronic components and the inner wall of the hole, causing the current to be unevenly distributed in the holes of the three-phase copper busbar, thereby generating a local high resistance area, resulting in an increase in resistance, and then causing the copper busbar to heat up.

[0005] To this end, the present invention provides a production method of a three-phase copper busbar. Summary of the invention

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention does not adsorb the magnet stone after the electromagnet is powered on and the power is turned off, so that the rotating column 2 contacts the surface of the copper plate until the punching hole on the copper plate is located below the rotating column 2. At this time, the rotating column 2 falls into the inside of the punching hole, and then the copper plate is stopped from being transported and the driving motor is started. The rotating column 1 rotates to drive the rotating column 2 and the grinder thereon to rotate, and the burrs on the inner wall of the punching hole of the copper plate are polished to make it smooth, thereby preventing the problem of heating of the copper busbar due to the burrs on the inner wall of the punching hole of the copper plate, and improving the quality and service life of the three-phase copper busbar.

[0026] 2. The present invention rotates the rotating column one counterclockwise, so that the guide column moves downward under the action of the rotating groove of the spiral groove, so that the piston rod drives the piston plate to squeeze the water in the piston cylinder, so that the water is sprayed into the space between the grinder and the punching hole on the rotating column two through the pipe two, and the water flows into the storage box after passing through the punching hole. In this process, the water flushes the debris and heat generated in the grinding process to prevent the inner wall of the punching hole on the copper plate from overheating during the grinding process, resulting in the inner wall of the copper plate being accumulated between the grinder and the inner wall of the punching hole due to debris, and the inner wall is squeezed as the grinder rotates, causing the inner wall to deform and generate new burrs. In addition, after the guide column enters the vertical groove of the spiral groove, the guide column is located at the top of the vertical groove through the elastic contraction of the spring, so that the water in the water tank flows into the piston cylinder to prepare for the next water spraying.

[0027] 3. The present invention rotates the rotating column 1 to make the sponge reciprocate under the guidance of the guide rod 4, so that during the process of polishing and spraying water, the upper surface of the copper plate at the polishing location and its surroundings is wiped to prevent some water containing polishing debris from being thrown onto the surface of the copper plate due to the rotation of the polisher during the polishing process.

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0046] Embodiment 1

[0047] like Figures 1 to 10 As shown, a method for producing a three-phase copper busbar according to an embodiment of the present invention is specifically as follows:

[0048] Preparation: pulling one end of the copper plate through the conveying device, then passing it through the straightening device, passing the copper plate through the punching machine, and finally passing it through the discharge port 11;

[0049] Stamping: Use a stamping machine to stamp the copper plate to form a circular connection port;

[0050] Bending and cutting: After the stamped copper plate passes through the discharge port 11, it is bent by the bending device 2 on the integrated machine body 1 until it is bent into a desired shape, and then the copper plate passing through the discharge port 11 is cut by the cutting device 3 so that it falls into the collection box below the integrated machine body 1;

[0051] Socketing and heat sealing: The copper busbar in the collection box is socketed on the plastic shell and heat-sealed to form a three-phase copper busbar.

[0052] Embodiment 2

[0053] like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is:

[0054] like Figures 2 to 6 As shown, the bending and cutting of this embodiment are specifically as follows: an output slot is provided on the integrated machine body 1, a discharge port 11 is fixed on the integrated machine body 1, the discharge port 11 is adapted to and communicated with the output slot on the integrated machine body 1, a bending device 2 is slidably provided on one side of the integrated machine body 1, a cutting device 3 is slidably provided on one side of the integrated machine body 1, and the bending device 2 and the cutting device 3 are on the same side;

[0055] The integrated machine body 1 is provided with a grinding assembly 4, which is composed of a moving device and a rotating device. The moving device includes an L-shaped guide groove 41, which is provided on the integrated machine body 1. The L-shaped guide groove 41 is composed of a horizontal slide groove and a vertical slide groove. One end of the horizontal slide groove is connected to the top of the vertical slide groove. A circular ring sleeve 416 is rotatably arranged in the L-shaped guide groove 41. A slider 3 49 is slidably arranged at one end of the integrated machine body 1 away from the discharge port 11. The slider 3 49 is symmetrically arranged on both sides of the integrated machine body 1. A rotating block 1 is rotatably connected inside the slider 3 49. 414, a guide rod 2 415 is fixedly connected to one side of the rotating block 1 414 close to the integrated machine body 1, a circular ring sleeve 416 is sleeved on the surface of the guide rod 2 415, a fixed plate 2 418 is fixedly connected to one side of another slider 3 49, and a support frame 419 is fixedly connected to one side of the fixed plate 2 418. When the slider 3 49 is displaced, the guide rod 2 415 and the circular ring sleeve 416 drive the other slider 3 49 to move, and then the fixed plate 2 418 drives the support frame 419 to move synchronously, ensuring that the grinding component 4 will not block the operation of the bending device 2 and the cutting device 3 when they are running;

[0056] The rotating device includes a rotating column 421, which is rotatably arranged on the lower surface of the top of the support frame 419. A rotating column 426 is slidably arranged inside the rotating column 421, and a grinder is arranged on the bottom surface of the rotating column 426. The rotating column 421 rotates to drive the rotating column 426 and the grinder thereon to rotate synchronously, thereby grinding the inner wall of the copper plate punching hole.

[0057] Specifically, after the copper plate is stamped, burrs will appear on the inner wall of the circular holes punched out. Since the stamped three-phase copper busbar is often used as a connecting structure with other electronic components, when the wires of other electronic components pass through the holes of the three-phase copper busbar, the burrs on the inner wall of the hole will contact the wires of other electronic components, resulting in a reduction in the contact area between the wires of other electronic components and the inner wall of the hole, causing the current to be unevenly distributed in the holes of the three-phase copper busbar, thereby generating a local high-resistance area, resulting in an increase in resistance, and then causing the copper busbar to heat up.

[0058] Therefore, the present invention solves this problem by setting a corresponding structure. The grinding component 4 is set on the integrated machine body 1, and the copper plate is polished before being bent, so that the staff can better observe the state and details of the grinding and make adjustments more convenient.

[0059] After the copper plate passes through the discharge port 11, the copper wire passes through the inside of the support frame 419, and the second rotating column 426 contacts the surface of the copper plate until the punching hole on the copper plate is located below the second rotating column 426. At this time, the second rotating column 426 falls into the inside of the punching hole, and then the copper plate is stopped and the first rotating column 421 is rotated, so that the second rotating column 426 and the grinder thereon rotate to grind the inner wall of the punching hole of the copper plate;

[0060] When the copper plate needs to be bent, the slider 3 49 is moved, and the other slider 3 49 is driven to move synchronously under the action of the rotating block 1 414 and the annular sleeve 416 sliding in the L-shaped guide groove 41, so that the rotating device on the fixed plate 2 418 only performs an L-shaped displacement in the vertical plane, so that the rotating device does not block the operation of the bending device 2 and the cutting device 3, and then the bending device 2 is started to bend the copper plate passing through the rotating column 2 426, until the bending device 2 is reset, the slider 3 49 is reset, and then the rotating device is reset, and then the copper plate is continued to be transported;

[0061] When the copper plate needs to be cut, the above operation is repeated to complete the cutting, and the cut copper bar falls into a collection box arranged below the integrated machine body 1 .

[0062] like Figures 2 to 6As shown, the mobile device of this embodiment also includes a fixed bracket 42, which is fixed to a side of the integrated machine body 1 away from the discharge port 11, and a hydraulic cylinder 43 is fixedly connected to the fixed bracket 42. A guide block 44 is fixedly connected to the integrated machine body 1, and the guide block 44 is located between the output groove of the integrated machine body 1 and the horizontal slide groove of the L-shaped guide groove 41. A slider 45 is slidably connected to the guide block 44, and the slider 45 slides on the guide block 44. The output end of the fixed bracket 42 is fixed to one side of the slider 45, and a slide rail 46 is fixedly connected to the surface of one side of the integrated machine body 1. The vertical slide groove of the L-shaped guide groove 41 is located between the slide rails 46, and a slider 47 is slidably connected to the slide rail 46. A guide block 48 is fixedly connected to one side of the slider 47.

[0063] The slider 3 49 at one end away from the discharge port 11 is fixedly connected to a fixed plate 410 near the end of the slide rail 46, the slider 45 is fixedly connected to a rotating rod 411 at the side away from the integrated machine body 1, the fixed plate 410 is fixedly connected to a rotating rod 412 at the side away from the integrated machine body 1, a guide rod 413 is rotatably connected between the rotating rod 411 and the rotating rod 412, an L-shaped guide rail 417 is fixedly connected to the integrated machine body 1, the L-shaped guide rail 417 is located on the side where the discharge port 11 is located, the L-shaped guide groove 41 is located between the L-shaped guide rails 417, and the slider 3 49 near the discharge port 11 slides in the L-shaped guide rail 417.

[0064] Specifically, when bending or cutting is required, on the side of the integrated machine body 1 away from the discharge port 11, the hydraulic cylinder 43 is started, and the slider 1 45 is pushed to slide on the guide block 1 44 through the output end of the hydraulic cylinder 43. Under the action of the guide rod 1 413, the slider 3 49 slides on the guide block 2 48 until the slider 3 49 slides to the other end of the guide block 2 48. There are two circular sleeves 416 and two guide rods 415. Under the action of the guide rod 2 415 and the circular sleeve 416, the other slider 3 49 slides in the L-shaped guide rail 417.

[0065] When the first annular sleeve 416 is located at the same position of the horizontal slide groove and the top of the vertical slide groove of the L-shaped guide groove 41, the first annular sleeve 416 slides into the vertical slide groove, thereby driving the rotating block 1 414 to rotate inside the slider 3 49. At this time, the guide rod 1 413 rotates, and as the slider 1 45 continues to move, the guide block 2 48 is pushed by the force of the guide rod 1 413. During this process, another annular sleeve 416 also slides into the vertical slide groove of the L-shaped guide groove 41, and the guide block 2 48 drives the slider 2 47 to slide on the slide rail 46. The slider 3 49 in the L-shaped guide rail 417 slides into the vertical part of the L-shaped guide rail 417, thereby driving the rotating device to not block the movement of the bending equipment 2 and the cutting equipment 3.

[0066] like Figures 6 to 9As shown, the rotating device of this embodiment also includes a driving motor 422, which is fixed on the top of the support frame 419. A storage box 420 is fixedly connected to the upper surface of the bottom of the support frame 419 for collecting dropped objects in the process of grinding metal burrs. A rectangular groove 423 is opened inside the rotating column 1 421, and an electromagnet 424 is fixedly connected to one end of the rectangular groove 423 close to the top of the support frame 419. A magnet 425 is slidably connected in the rectangular groove 423, and the bottom of the magnet 425 is fixedly connected to the rotating column 2 426.

[0067] Specifically, the electromagnet 424 is externally connected with a power line. When the bending device 2 or the cutting device 3 is in operation, the electromagnet 424 is energized to generate a magnetic field and adsorb the magnet 425, thereby causing the second rotating column 426 to move upward. The bottom of the second rotating column 426 is set to be arc-shaped, which reduces the contact area between the bottom of the second rotating column 426 and the copper plate, thereby reducing friction and making the second rotating column 426 easier to slide on the surface of the copper plate;

[0068] When the bending device 2 or the cutting device 3 is reset, the moving device is reset by the moving device. At this time, the rotating column 426 is located above the copper plate, and then the electromagnet 424 is powered off, the electromagnet 424 and the magnet 425 are no longer adsorbed, and the rotating column 426 is in contact with the upper surface of the copper plate until the punching hole on the copper plate is located below the rotating column 426. At this time, the rotating column 426 falls into the punching hole, and then the copper plate is stopped from being transported and the driving motor 422 is started. The rotating column 421 is rotated to drive the rotating column 426 and the grinder thereon to rotate, and the burrs on the inner wall of the punching hole of the copper plate are polished to make it smooth, thereby preventing the problem of heating of the copper busbar due to burrs on the inner wall of the punching hole of the copper plate, thereby improving the quality and service life of the three-phase copper busbar.

[0069] like Figures 6 to 9 As shown, in this embodiment, a spray assembly 5 is provided on the support frame 419, and the spray assembly 5 is used for spraying water during grinding. The spray assembly 5 includes a fixed block 51, and the fixed block 51 is fixed to the lower surface of the top of the support frame 419. The bottom end of the fixed block 51 is fixedly connected to a piston cylinder 52, and a piston rod 53 is slidably connected inside the piston cylinder 52. The piston rod 53 consists of a rectangular rod and a cylindrical rod, and a piston plate 54 is fixedly connected to the bottom of the rectangular rod of the piston rod 53. The piston plate 54 slides in the piston cylinder 52, and a spring 55 is fixedly connected between the piston plate 54 and the inner surface of the top of the piston cylinder 52. A water tank 511 is fixedly connected to the top of the support frame 419, a pipe 1 56 is fixedly connected between the bottom of the water tank 511 and the bottom of the piston cylinder 52, and a pipe 2 57 is fixedly connected to the bottom of the piston cylinder 52.

[0070] Specifically, initially, water is stored between the bottom of the piston cylinder 52 and the piston plate 54, a one-way valve 1 is provided at the connection between the pipe 1 56 and the piston cylinder 52, and a one-way valve 2 is provided between the connection between the pipe 2 57 and the piston cylinder 52, and the directions of the one-way valve 1 and the one-way valve 2 are opposite;

[0071] When the piston rod 53 moves downward, the spring 55 is elastically stretched, and the piston plate 54 squeezes the water through the second pipe 57 and sprays it into the space between the grinder and the punching hole on the second rotating column 426 through the movement of the piston rod 53;

[0072] When the piston rod 53 moves upward, the spring 55 elastically contracts, causing the piston rod 53 to accelerate upward movement until the piston rod 53 is reset. At this time, the space between the piston plate 54 and the bottom of the piston cylinder 52 becomes larger, and the pressure increases, causing the water in the water tank 511 to flow into the piston cylinder 52 through the pipe 56, preparing for the next water spray.

[0073] like Fig. 9 As shown, the spray assembly 5 of this embodiment also includes a guide rod 3 58, one end of the guide rod 3 58 is fixed to the cylindrical rod surface of the piston rod 53, and the end of the guide rod 3 58 close to the rotating column 1 421 is fixedly connected to the guide column 59, and the surface of the rotating column 1 421 is provided with a spiral groove 510, and the guide column 59 slides in the spiral groove 510. The spiral groove 510 consists of a rotating groove and a vertical groove, the top of the rotating groove is connected to the top of the vertical groove, and the bottom of the rotating groove is connected to the bottom of the vertical groove, and the depth of the rotating groove gradually becomes shallower from the top to the bottom.

[0074] Specifically, the rectangular rod portion of the piston rod 53 slides inside the piston cylinder 52, and the piston cylinder 52 is fixed by the fixing block 51;

[0075] When the rotating column 421 rotates counterclockwise, the guide column 59 is moved from the top to the bottom under the guidance of the rotating groove of the spiral groove 510, and then drives the piston rod 53 to move downward through the guide rod 3 58. At this time, the guide column 59 is located in the vertical groove part of the spiral groove 510. Because the depth of the rotating groove gradually becomes shallower from the top to the bottom, the guide column 59 can only slide in the vertical groove of the spiral groove 510, and then under the action of the upward movement of the piston rod 53, the guide column 59 slides into the top of the vertical groove of the spiral groove 510.

[0076] The present invention rotates the rotating column 421 counterclockwise to make the guide column 59 move downward under the action of the rotating groove of the spiral groove 510, so that the piston rod 53 drives the piston plate 54 to squeeze the water in the piston cylinder 52, so that the water is sprayed into the space between the grinder and the punching hole on the rotating column 426 through the pipe 57, and the water flows into the storage box 420 after passing through the punching hole. In this process, the water washes away the debris and heat generated during the grinding process to prevent the inner wall of the punching hole on the copper plate from overheating during the grinding process, resulting in the inner wall of the copper plate being accumulated between the grinder and the inner wall of the punching hole due to debris, and the inner wall is squeezed as the grinder rotates, causing the inner wall to deform and generate new burrs. In addition, after the guide column 59 enters the vertical groove of the spiral groove 510, the guide column 59 is located at the top of the vertical groove through the elastic contraction of the spring 55, so that the water in the water tank 511 flows into the piston cylinder 52 to prepare for the next water spraying.

[0077] like Figures 6 to 8 and Fig.10 As shown, a cleaning assembly 6 is provided on the support frame 419 of this embodiment. The cleaning assembly 6 is used to clean the surface of the copper plate at the grinding location during grinding. The cleaning assembly 6 includes a rotating bevel gear rod 62, and the rotating bevel gear rod 62 is fixed to the lower surface of the top of the support frame 419. A pulley 61 is fixedly connected to the surface of the rotating column 421, and a pulley 2 63 is fixedly connected to the surface of the rotating bevel gear rod 62. A belt 64 is connected for transmission between the pulley 1 61 and the pulley 2 63. A transmission bevel gear rod 65 is rotatably connected inside the support frame 419, and the transmission bevel gear on the transmission bevel gear rod 65 is meshed with the rotating bevel gear on the rotating bevel gear rod 62.

[0078] Specifically, when the rotating column 421 rotates, the rotating bevel gear rod 62 is rotated through the belt 64, and then the transmission bevel gear rod 65 is driven to rotate through the meshing between the bevel gears.

[0079] like Figure 8 and Fig.10 As shown, the cleaning assembly 6 of this embodiment also includes a reciprocating screw 67, which is rotatably connected between the inner walls of the support frame 419, one end of the transmission bevel gear rod 65 is fixedly connected to a pulley three 66, one end of the reciprocating screw 67 is fixedly connected to a pulley four 68, a belt two 69 is transmission-connected between the pulley three 66 and the pulley four 68, two guide rods four 610 are rotatably connected between the inner walls of the support frame 419, a fixed frame 614 is slidably connected between the guide rods four 610, a displacement plate 611 is fixedly connected to the top of the fixed frame 614, a hole is provided in the middle of the displacement plate 611, the reciprocating screw 67 passes through the hole on the displacement plate 611, the top of the displacement plate 611 is rotatably connected to a rotating block two 612, the bottom end of the rotating block two 612 is fixedly connected to an arc plate 613, the arc plate 613 slides on the reciprocating screw 67, and a sponge 615 is fixedly connected to the bottom of the fixed frame 614.

[0080] Specifically, the reciprocating screw rod 67 is symmetrically arranged, two pulleys 3 66 are arranged, located at both ends of the transmission bevel gear rod 65, and pulleys 4 68 are arranged on the two reciprocating screw rods 67, respectively located at both ends of the pulleys 4 68, and a belt 2 69 is arranged between the pulleys 3 66 and the pulleys 4 68 at each end, and the guide rods 4 610 are symmetrically arranged, and the structures on the guide rods 4 610 and the reciprocating screw rods 67 are symmetrically arranged;

[0081] When the transmission bevel gear rod 65 rotates, the reciprocating screw rod 67 is driven to rotate through the belt 2 69, and then the arc plate 613 drives the displacement plate 611. Under the limiting action of the reciprocating screw rod 67 and the guide rod 4 610, only horizontal displacement is performed, so that the fixed frame 614 drives the sponge 615 to move synchronously. When the arc plate 613 moves to one end of the reciprocating thread groove, the arc plate 613 drives the rotating block 2 612 to rotate in the displacement plate 611 through the guidance of the thread groove, and then slides into the thread groove on the other side, thereby driving the sponge 615 to reciprocate.

[0082] The present invention rotates the rotating column 421 to make the sponge 615 reciprocate under the guidance of the guide rod 4 610, so that during the process of grinding and spraying water, the upper surface of the copper plate at and around the grinding area is wiped to prevent some water containing grinding debris from being thrown onto the surface of the copper plate due to the rotation of the grinder during the grinding process.

[0083] Working principle:

[0084] After the copper plate passes through the discharge port 11, the copper wire passes through the inside of the support frame 419. At this time, the second rotating column 426 contacts the surface of the copper plate until the punching hole on the copper plate is located below the second rotating column 426. At this time, the second rotating column 426 falls into the inside of the punching hole, and then the copper plate is stopped and the rotating column 1 421 is rotated. The rotation of the rotating column 1 421 drives the second rotating column 426 and the grinder thereon to rotate, thereby completing the grinding of the burrs on the inner wall of the punching hole;

[0085] When the rotating column 1 421 rotates counterclockwise, the guide column 59 moves from the top to the bottom under the guidance of the rotating groove of the spiral groove 510, and then drives the piston rod 53 to move downward through the guide rod 3 58, so that the spring 55 is elastically stretched, and the piston plate 54 squeezes the water through the pipe 2 57 and sprays it into the space between the grinder and the punching hole on the rotating column 2 426 through the movement of the piston rod 53;

[0086] At this time, the guide post 59 is located in the vertical groove part of the spiral groove 510. Since the depth of the rotating groove gradually becomes shallower from the top to the bottom, the guide post 59 can only slide in the vertical groove of the spiral groove 510. Then the spring 55 elastically contracts, causing the piston rod 53 to move upward at an accelerated speed until the piston rod 53 is reset, causing the guide post 59 to slide into the top of the vertical groove of the spiral groove 510. At this time, the space between the piston plate 54 and the bottom of the piston cylinder 52 becomes larger, and the pressure increases, causing the water in the water tank 511 to flow into the piston cylinder 52 through the pipe 1 56, preparing for the next water spraying.

[0087] When the rotating column 421 rotates, the rotating bevel gear rod 62 is rotated through the belt 1 64, and then the transmission bevel gear rod 65 is driven to rotate through the meshing between the bevel gears, and the reciprocating screw rod 67 is driven to rotate through the belt 2 69, so that the arc plate 613 drives the displacement plate 611 to guide the reciprocating thread groove on the reciprocating screw rod 67, and only performs horizontal displacement under the limiting action of the two guide rods 4 610, so that the fixed frame 614 drives the sponge 615 to move synchronously. When the arc plate 613 moves to one end of the reciprocating thread groove, the arc plate 613 drives the rotating block 2 612 to rotate in the displacement plate 611 through the guidance of the thread groove, and then slides into the thread groove on the other side, thereby driving the sponge 615 to reciprocate.

[0088] When bending or cutting is required, on the side of the integrated machine body 1 away from the discharge port 11, the hydraulic cylinder 43 is started, and the slider 1 45 is pushed to slide on the guide block 1 44 through the output end of the hydraulic cylinder 43. Under the action of the guide rod 1 413, the slider 3 49 slides on the guide block 2 48 until the slider 3 49 slides to the other end of the guide block 2 48. There are two circular sleeves 416 and guide rods 2 415. Under the action of the guide rod 2 415 and the circular sleeve 416, the other slider 3 49 slides in the L-shaped guide rail 417.

[0089] When the first annular sleeve 416 is located at the same position of the transverse slide groove and the top of the vertical slide groove of the L-shaped guide groove 41, the first annular sleeve 416 slides into the vertical slide groove, thereby driving the rotating block 1 414 to rotate inside the slider 3 49. At this time, the guide rod 1 413 rotates. As the slider 1 45 continues to move, the guide block 2 48 is pushed by the guide rod 1 413. In this process, another annular sleeve 416 also slides into the vertical slide groove of the L-shaped guide groove 41. The guide block 2 48 drives the slider 2 47 to slide on the slide rail 46. The slider 3 49 in the L-shaped guide rail 417 slides into the vertical part of the L-shaped guide rail 417, thereby driving the rotating device to not block the movement of the bending device 2 and the cutting device 3.

[0090] Then, the bending device 2 or the cutting device 3 is started to bend or cut the copper plate passing through the rotating column 2 426, and the cut copper bar falls into the collection box provided below the integrated machine body 1;

[0091] When the bending device 2 or the cutting device 3 is running, the electromagnet 424 is energized to generate a magnetic field and adsorb the magnet 425, thereby causing the second rotating column 426 to move upward until the bending device 2 or the cutting device 3 is reset, and the output end of the hydraulic cylinder 43 is reset. Through the above operation, the rotating device is reset. At this time, the second rotating column 426 is located above the copper plate, and then the electromagnet 424 is powered off, the electromagnet 424 and the magnet 425 are no longer adsorbed, and the second rotating column 426 contacts the upper surface of the copper plate, and then the copper plate continues to be transported.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
