Description

Technical Field

[0001] The invention relates to the technical field of plate bending equipment, and in particular to a metal sheet punching and folding composite forming machine and a use method thereof. Background Art

[0002] Metal is a substance that has lustre (i.e. strong reflection of visible light), is ductile, and is easy to conduct electricity and heat. Most metal elements on Earth exist in nature in a chemical state. This is because the chemical properties of most metals are relatively active, and only a very small number of metals, such as gold and silver, exist in a free state.

[0003] Metal plates need to be bent during forming. Generally, when bending thin plates, the plates are basically placed on top of a bending device, and a large pressure is generated on the surface of the plates through a pressing device. The plates are bent after being subjected to force. Since generally existing bending devices basically directly punch the plates to bend them after placing them, there is almost no buffer space for the force on the plates. As a result, when the plates are bent, stress is easily concentrated at the bending parts of the plates, which causes stress concentration at the bending parts of the plates, and easily causes deformation of the plates when bending. When thinner plates are bent, cracks are also easily generated at the bending parts, affecting the bending efficiency. Summary of the invention

[0017] A method for using a metal sheet punching and folding composite forming machine, the method comprising the following steps:

[0018] S1: First, the staff places the plate on the conveyor and moves the bending part to be bent to the middle of the fixed frame;

[0019] S2: Then start the hydraulic rod, which will push the bending plate to descend when working. The bending plate will punch the plate when descending to complete the bending work on the plate.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the bending plate punches the plate, the plate will complete the bending work between the two moving blocks. When the plate is bent between the moving blocks, the bent plate will squeeze the moving block after bending. After being squeezed, the moving block will drive the second fixed rod to slide inside the fixed frame. When sliding, the moving block will push the special-shaped plate to rotate slightly around the first fixed rod. When the special-shaped plate is rotating, the rotating special-shaped plate will push the working frame through the inclined rod to make the working frame rise on the outer surface of the fixed cylinder and fit with the bending part of the plate. When the plate is in the process of bending, the bending part of the plate will form a corner, and the corner will squeeze the arc plate. At the same time, the surface of the bending part will fit with the C-shaped axis. After being squeezed, the arc plate will push the rotating Rod, so that the rotating rod rotates with the long rod as the center. When the rotating rod rotates, the rotating rotating rod will push the moving sleeve to slide on the surface of the special-shaped shaft. When the moving sleeve slides, the special-shaped shaft will rotate when the moving sleeve moves through the contact of the spring plate 2 on the surface of the special-shaped shaft. When the special-shaped shaft rotates, it will drive the sliding plate through the inclined axis to make the sliding plate slide back and forth on the surface of the C-shaped shaft. When the sliding plate slides, it will knock on the C-shaped shaft. At this time, when the C-shaped shaft is attached to the surface of the corner of the plate, it can provide certain support and protection for the plate and help disperse the stress at the bending. At the same time, the reciprocating sliding plate can also disperse the stress at the bending when knocking the C-shaped shaft, so as to prevent deformation due to excessive concentration of stress at the bending, thereby reducing the risk of damage to the plate.

[0022] When the movable rod moves upward, the friction plate will be fitted to the bottom surface of the plate, and at the same time, when the movable rod moves upward, the friction plate will rotate with the bending angle of the plate and always fit the surface of the plate. When the friction plate rotates, the friction plate will squeeze the rack, and the rack will drive the two-way toothed plate to rotate after being squeezed. When the two-way toothed plate rotates, the racks on both sides will be dislocated and push the friction plate, so that the friction plate and the plate are fitted together. When the friction plate and the plate are fitted together, the rebound of the plate during the bending process and after the bending is completed can be reduced. At the same time, when the friction plate and the plate are fitted together, the plate is subjected to more uniform force during the bending process, and the local deformation and rebound caused by uneven force can be reduced.

[0023] 3. In the present invention, when the friction plate rotates along with the bending degree of the plate, the rotating friction plate will push the two-way toothed plate to rotate through the rack, and the two-way toothed plate will drive the fixed rod to rotate when rotating, and the fixed rod will drive the worm wheel to rotate through the worm, and the worm wheel will drive the worm wheel to rotate with the square plate through the L rod when rotating. At the same time, when the worm wheel rotates, the long groove on the worm wheel will drive the H axis to rotate in the second special-shaped plate, and the H axis will generate shear force on the special-shaped frame inside the special-shaped frame when rotating. After being subjected to the shear force, the special-shaped frame will push the hollow cylinder to move inside the sliding groove, and when the hollow cylinder moves, the moving hollow cylinder will drive the limit frame and the adsorption frame to move at the bottom of the plate, and when the hollow cylinder moves, the push rod will squeeze the gas inside the hollow cylinder, and when the hollow cylinder moves, the moving hollow cylinder will move in the air Negative pressure is generated between the core tube and the pushing rod. At this time, the generation of negative pressure will generate adsorption force inside the adsorption tube, and the generation of adsorption force will extract the gas inside the adsorption frame. After the gas inside the adsorption frame is extracted, the adsorption frame will generate adsorption force on the plate and adsorb on the surface of the plate. Later, when the special-shaped frame pushes the hollow tube to move, the adsorption frame adsorbed on the bottom of the plate will form a pushing force on the plate. At this time, when the plate just begins to bend and deforms under force, the moving adsorption frame will push the plate through the adsorption force. Since the moving mechanism and auxiliary mechanism on the left and right sides of the fixed frame are symmetrically arranged, when the adsorption frame pushes the plate, the deviation of the plate during bending can be reduced, and the lateral movement of the plate can be further limited, thereby reducing the overall movement of the plate during the bending process and reducing the bending error caused by movement.

[0024] 4. In the present invention, when the special-shaped frame is pushed by the shear force of the H-axis to move the hollow cylinder, the moving hollow cylinder will move inside the sliding groove. When the hollow cylinder moves, the pushing rod will squeeze the gas inside the hollow cylinder. After being squeezed, the gas will enter the hollow plate through the air inlet pipe, and enter several airbag shafts through the hollow plate. At this time, the airbag shaft will expand. The expanded airbag shaft will increase the friction area between the limit frame and the plate. At the same time, when the plate is deformed by force, the airbag shaft will push the hollow plate to rotate slightly on the surface of the adsorption frame, so that part of the airbag shaft can always contact the plate, and the softness and elasticity of the airbag shaft can absorb the vibration and impact generated during partial bending. At the same time, after the airbag shaft increases the friction area with the plate, the adsorption frame can further enhance the push of the plate, enhance the pushing force of the adsorption frame, and further reduce the movement of the plate when it is bent by force.

When the fixed rod 501 rotates, it will drive the worm wheel 503 to rotate through the worm 502, and when the worm wheel 503 rotates, it will push the worm wheel 503 to rotate with the square plate through the L rod 507.

The connecting end is located between the pushing rod 602 and the hollow cylinder 601, and the end of the adsorption tube 605 away from the hollow cylinder 601 is connected to the adsorption frame 604. The side of the hollow cylinder 601 close to the adsorption tube 605 is fixedly connected with an air inlet pipe 606, and the air inlet pipe 606 is connected to the hollow cylinder 601. When the hollow cylinder 601 moves, the moving hollow cylinder 601 will drive the limit frame 603 and the adsorption frame 604 to move at the bottom of the plate, and when the hollow cylinder 601 moves, the pushing rod 602 will squeeze the gas inside the hollow cylinder 601, and when the hollow cylinder 601 moves, the moving hollow cylinder 601 will generate negative pressure between the hollow cylinder 601 and the pushing rod 602.

When the special-shaped frame 506 is pushed by the shear force of the H-axis 505 to move the hollow cylinder 601, the moving hollow cylinder 601 will be in the sliding groove 508. When the hollow cylinder 601 moves inside, the push rod 602 will squeeze the gas inside the hollow cylinder 601. After being squeezed, the gas will enter the hollow plate 701 through the air inlet pipe 606, and enter the airbag shafts 702 through the hollow plate 701. At this time, the airbag shaft 702 will expand. The expanded airbag shaft 702 will increase the friction area between the limit frame 603 and the plate.

[0052] A method for using a metal sheet punching and folding composite forming machine, the method comprising the following steps:

[0053] S1: First, a staff member places the plate on the conveyor 101 and moves the bending part to be bent to the middle of the fixed frame 104;

[0054] S2: Then the hydraulic rod 102 is started. When the hydraulic rod 102 is working, it will push the bending plate 103 to descend. When the bending plate 103 descends, it will punch the plate to complete the bending work on the plate.

[0055] When in use, the staff first places the plate on the conveying body 101 and moves the bending point to be bent to the middle of the fixed frame 104, and then starts the hydraulic rod 102. The hydraulic rod 102 will push the bending plate 103 down when working, and the bending plate 103 will punch the plate when descending to complete the bending work on the plate. When the bending plate 103 punches the sheet, the sheet will complete the bending work between the two moving blocks 206. When the sheet is bent between the moving blocks 206, the bent sheet will squeeze the moving block 206 after bending. After being squeezed, the moving block 206 will drive the fixed rod 205 to slide inside the fixed frame 104. When sliding, the moving block 206 will push the special-shaped plate 202 to rotate slightly around the fixed rod 1 201. When the special-shaped plate 202 is rotating, the rotating special-shaped plate 202 will push the working frame 302 through the inclined rod 301 so that the working frame 302 rises on the outer surface of the fixed cylinder 304 and fits with the bending part of the sheet. When the sheet is in the process of bending, the bending part of the sheet will form a corner, and the corner will squeeze the arc plate 305. At the same time, the surface of the bending part will fit with the C-shaped shaft 310. After being squeezed, the arc plate 305 will push the rotating rod 306, so that The rotating rod 306 rotates with the long rod as the center. When the rotating rod 306 rotates, the rotating rotating rod 306 will push the moving sleeve 307 to slide on the surface of the special-shaped shaft 309. When the moving sleeve 307 slides, the special-shaped shaft 309 will rotate when the moving sleeve 307 moves through the contact of the spring plate 2 308 on the surface of the special-shaped shaft 309. When the special-shaped shaft 309 rotates, it will drive the sliding plate 311 through the inclined axis 312 to make the sliding plate 311 slide back and forth on the surface of the C-shaped shaft 310. When the sliding plate 311 slides, it will knock on the C-shaped shaft 310. At this time, when the C-shaped shaft 310 is attached to the surface of the corner of the plate, it can provide certain support and protection for the plate, help disperse the stress at the bending point, and at the same time, the reciprocating sliding plate 311 can also disperse the stress at the bending point when knocking the C-shaped shaft 310, prevent deformation caused by excessive concentration of stress at the bending point, and reduce the risk of damage to the plate.When the inclined rod 301 pushes the working frame 302 and the outer cylinder 303 to slide upward on the surface of the fixed cylinder 304, the sliding outer cylinder 303 will pull the arc plate 2 402 to rotate on the triangular plate through the pull rope 401, and the arc plate 2 402 will push the moving rod 403 to move upward when rotating. When the moving rod 403 moves, the friction plate 407 will fit the bottom surface of the plate. At the same time, when the arc plate 2 402 pushes the moving rod 403 to rise, the friction plate 407 will rotate with the bending angle of the plate and always fit the surface of the plate. When the friction plate 407 is rotating, the friction plate 407 will squeeze the rack 406, and the rack 406 will drive the two-way tooth plate 404 to rotate after being squeezed. When the two-way tooth plate 404 rotates, the racks 406 on both sides will be misaligned and push the friction plate 407, so that the friction plate 407 and the plate will fit together. When the friction plate 407 and the plate are fitted together, the rebound of the plate during the bending process and after the bending is completed can be reduced. At the same time, when the friction plate 407 and the plate are fitted together, the plate is subjected to a more uniform force during the bending process, and the local deformation and rebound caused by uneven force can be reduced.When the friction plate 407 rotates with the bending degree of the plate, the rotating friction plate 407 will push the two-way tooth plate 404 to rotate through the rack 406. When the two-way tooth plate 404 rotates, it will drive the fixed rod 501 to rotate. When the fixed rod 501 rotates, it will drive the worm wheel 503 to rotate through the worm 502. When the worm wheel 503 rotates, it will push the worm wheel 503 to rotate with the square plate through the L rod 507. At the same time, when the worm wheel 503 rotates, the long slot on the worm wheel 503 will drive the H The shaft 505 rotates in the special-shaped plate 504. When the shaft 505 rotates, it will generate a shear force on the special-shaped frame 506 inside the special-shaped frame 506. After the special-shaped frame 506 is subjected to the shear force, it will push the hollow cylinder 601 to move inside the sliding groove 508. When the hollow cylinder 601 moves, the moving hollow cylinder 601 will drive the limit frame 603 and the adsorption frame 604 to move at the bottom of the plate. When the hollow cylinder 601 moves, the push rod 602 will squeeze the gas inside the hollow cylinder 601 and When the hollow cylinder 601 moves, the moving hollow cylinder 601 will generate negative pressure between the hollow cylinder 601 and the pushing rod 602. At this time, the generation of negative pressure will generate adsorption force inside the adsorption tube 605, and the generation of adsorption force will extract the gas inside the adsorption frame 604. After the gas inside the adsorption frame 604 is extracted, the adsorption frame 604 will generate adsorption force on the plate and adsorb on the surface of the plate. Thereafter, when the special-shaped frame 506 pushes the hollow cylinder 601 to move, the adsorption frame 604 adsorbed on the bottom of the plate will form a driving force on the plate. At this time, when the plate just begins to bend and is deformed by force, the moving adsorption frame 604 will push the plate through the adsorption force. Since the moving mechanism 6 and the auxiliary mechanism 5 on the left and right sides of the fixed frame 104 are symmetrically arranged, when the adsorption frame 604 pushes the plate, the deviation of the plate during bending can be reduced, and the lateral movement of the plate can be further limited, thereby reducing the overall movement of the plate during the bending process and reducing the bending error caused by movement.When the special-shaped frame 506 is pushed by the shear force of the H-axis 505 to move the hollow cylinder 601, the moving hollow cylinder 601 will move inside the sliding groove 508. When the hollow cylinder 601 moves, the push rod 602 will squeeze the gas inside the hollow cylinder 601. After being squeezed, the gas will enter the hollow plate 701 through the air inlet pipe 606, and enter the several airbag shafts 702 through the hollow plate 701. At this time, the airbag shaft 702 will expand. The expanded airbag shaft 702 will increase the friction between the limit frame 603 and the plate. When the plate is deformed under force, the airbag shaft 702 will push the hollow plate 701 to make a slight rotation on the surface of the adsorption frame 604, so that part of the airbag shaft 702 can always be in contact with the plate, and the softness and elasticity of the airbag shaft 702 can absorb the vibration and impact generated during partial bending. At the same time, after the airbag shaft 702 increases the friction area with the plate, the adsorption frame 604 can further enhance the push of the plate, enhance the pushing force of the adsorption frame 604, and further reduce the movement of the plate when it is bent under force.
