[0004] Since the steel plate is bent as a whole after being stretched from the coiled state, it is necessary to level the steel plate to make it straight when cutting it, so as to avoid cutting the steel plate in a bent state, resulting in irregular cutting shapes and affecting the cutting accuracy of the steel plate. Therefore, it is necessary to design a steel plate shearing device with an automatic leveling function to prevent the bending of the steel plate from affecting the cutting accuracy. Summary of the invention

[0005] The object of the present invention is to provide a steel plate shearing device with an automatic leveling function to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a steel plate shearing device with automatic leveling function, comprising a cutting frame, a cutting frame is arranged at the top of the cutting frame, a cutting machine is arranged on the inner side of the cutting frame, and a collecting box is arranged on the inner side of the top of the cutting frame; cutting and leveling components are arranged on both sides of the cutting frame, and the cutting and leveling components include a leveling press frame, a press frame slide bar, a press frame roller, a pressure slide bar, an inclined groove slider, a top pressure roller, a connecting rod, a support block, and a bidirectional screw, the leveling press frame is rotatably connected to the side of the cutting frame, the press frame slide bar is fixedly connected to the bottom side of the leveling press frame, and the press frame roller is rotatably connected At the end of the pressure frame slide rod, the pressure slide rod is slidably connected to the side of the pressure frame slide rod, the inclined groove slider is slidably connected to the side of the collection box, the top pressure roller is rotatably connected to the inner side of the inclined groove slider, the connecting rod is connected to the outer side of the top pressure roller shaft, the support block is slidably connected to the inner side of the collection box, the bidirectional screw is rotatably connected to the inner side of the support block, the cutting machine is slidably connected to the cutting frame, the cutting frame is fixedly connected to the cutting stand, the top pressure roller is rotatably connected to the connecting rod, the support block is hingedly connected to the connecting rod, the pressure slide rod is fixedly connected to the inclined groove slider, and the side of the collection box is provided with a vertical center line of the collection box. The cutting machine is driven by a built-in motor to slide along the structure of the cutting frame to cut and cut the plate. When the bidirectional screw is driven to rotate by the motor built in the collecting box, the rotation of the bidirectional screw will drive the support blocks connected on both sides to rotate, so that the two support blocks are close to or away from each other. When the two support blocks are close to each other and slide along the inside of the collecting box, the support block will drive the inclined slot slider to slide through the connecting rod connected on the side, so that the inclined slot slider slides along the inclined slot on the side of the collecting box, and the top pressure roller connected to the inclined slot slider will move upward together, and gradually make the top side of the top pressure roller consistent with the top surface of the support block, so that the support The block and the top pressure roller together support the steel plate. The support block and the top pressure roller provide support for the steel plate during cutting to prevent the cutting machine from causing damage to objects other than the steel plate or the structure inside the device. At the same time, the movement of the inclined slot slider will drive the connected pressure slide bar to move together, so that the pressure slide bar and the pressure frame slide bar can slide against each other, and the pressure slide bar can pull the leveling pressure frame downward to deflect and apply pressure, so that the leveling pressure frame deflects and drives the bottom pressure frame roller to squeeze, and cooperates with the top pressure roller to apply pressure, and the bent steel plate is rolled and flattened by the pressure of the top pressure roller. When cutting the steel plate, the bent steel plate is leveled to prevent the bending of the steel plate from affecting the cutting accuracy.

[0007] According to the above technical scheme, a material pushing and unloading device is arranged on the inner side of the top end of the cutting frame, and the material pushing and unloading device includes a material pushing table, an auxiliary roller, a width limiting plate, a driving motor, a threaded rod, a sliding frame, a toothed roller shaft, a connecting roller rod, an extension rod, a material pushing rod, and an arc groove rod. The material pushing table is fixedly connected to the inner side surface of the cutting frame, the auxiliary roller is rotatably connected to the inner side of the material pushing table, the width limiting plate is fixedly connected to the surface of the material pushing table, the driving motor is fixedly connected to the inner side of the cutting frame, the threaded rod is fixedly connected to the end of the output shaft of the driving motor, the sliding frame is threadedly connected to the outer side of the threaded rod, the toothed roller shaft is meshingly connected to the bottom side surface of the sliding frame, and the connecting roller rods at two places are respectively fixedly connected At the left and right ends of the gear roller shaft, the extension rod is slidably connected to the inner top of the connecting roller rod, the push rod is slidably connected to the inner side of the extension rod, the curved arc groove rod is fixedly connected to the inner side of the top of the cutting platform, the inner side of the bottom end of the cutting platform is fixedly connected with a square rail, and the square rail is slidably connected to the sliding frame, and a tooth groove is provided on the bottom side of the sliding frame, and the tooth groove is meshed with the surface of the gear roller shaft, a sliding groove is provided on the inner side of the extension rod, and the sliding groove is slidably connected to the push rod, and a spring is provided in the sliding groove, and the top and bottom ends of the spring are respectively fixedly connected to the push rod and the extension rod, a side sliding rod is provided on the side of the extension rod, and the side sliding rod is slidably connected to the curved arc groove rod, a spring is provided on the inner side of the connecting roller rod, and the top of the spring The cam is fixedly connected to the extension rod, and the bottom end of the spring is fixedly connected to the connecting roller rod. When the driving motor rotates, the threaded rod connected to the output shaft will be driven to rotate, and the sliding frame will be driven to slide along the two sides of the square rail through the rotation of the threaded rod, so that the tooth groove on the bottom side of the sliding frame engages the toothed roller shaft, so that the toothed roller shaft rotates to drive the connecting roller rod to deflect. During the deflection and movement of the connecting roller rod, the connecting roller rod drives the extension rod to slide from one end to the other along the curved arc groove rod through the side sliding rod, pushing the steel plate onto the surface of the pushing table, so that the steel plate on the pushing table is pushed by external force through the auxiliary roller and rolled into the inner side of the width limiting plate until the edge of the steel plate passes over the pushing rod. Since the pushing rod is pulled by the spring, the pushing rod is always in contact with the pushing table under the action of the spring tension, and the pushing rod is pulled by the connecting roller. When the rod is deflected, the push rod will push the steel plate. During this process, the extension rod slides along the curved groove rod through the side sliding rod, which will cause part of the extension rod structure to shrink into the inside of the connecting roller rod, and as the connecting roller rod rotates, the push rod will gradually push the steel plate to the bottom of the cutting machine for cutting. After the cutting is completed, as the connecting roller rod continues to rotate, the extension rod extends from the connecting roller rod to push the cut steel plate to the specified position, thereby pushing the steel plate to move a long distance without affecting the cutting. At the same time, when the connecting roller rod swings from the rear end to the front end, the debris scattered from the cut steel plate onto the pushing table is pushed into the groove in the middle of the pushing table through the push rod to prevent particles from scattering onto the pushing table to avoid affecting the flatness of the steel plate, thereby affecting the cutting of the steel plate.

[0008] According to the above technical solution, a buffer device is provided on the rear side of the cutting stand, and the buffer device includes a pressure rod, a pressure arc rod, a pressure flap, a pressure rod pressure block, a baffle, a vertical slot plate, a buffer arc block, a tilting frame, and a buffer rod. The pressure rod is fixedly connected to the side of the sliding frame, the pressure arc rod is fixedly connected to the top of the pressure rod, the pressure flap is hingedly connected to the bottom surface of the top of the cutting stand, the two pressure rod pressure blocks are respectively fixedly connected to the left and right ends of the pressure flap, the baffle is fixedly connected to the top of the rear side of the cutting stand, and the vertical slot plate is fixedly connected to the rear of the cutting stand. The side surface, the buffer arc block is fixedly connected to the inner side surface of the vertical slot plate, the tilting frame is fixedly connected to the rear side surface of the vertical slot plate, the buffer rod is slidably connected to the side surface of the tilting frame, the rear side surface of the buffer rod is provided with a spring, and the front end of the spring is fixedly connected to the buffer rod, and the rear end of the spring is fixedly connected to the tilting frame, the touch rod pressure block corresponds to the position of the pressure arc rod, the side surface of the pressure flap is provided with a torsion spring, and the inner end of the torsion spring is fixedly connected to the pressure flap, and the outer end of the torsion spring is fixedly connected to the baffle, and the cut steel plate is pushed to the inclined surface at the rear side of the pushing table. The pressure plate is blocked by the pressure flap, and the steel plate slides along the slope and passes through the surface of the push plate. At this time, the pressure flap first acts as a buffer for the steel plate to slide along the inclined surface of the push plate. Subsequently, the sliding frame moves from the front end to the rear end of the inner side of the cutting frame, and the movement of the sliding frame drives the pressure rods on both sides to move, so that the pressure rods touch the pressure rod blocks on both sides of the pressure flap, and the pressure rod blocks are compressed to deflect the pressure plate. The deflection of the pressure flap will make the top gradually approach the surface of the steel plate, and make the steel plate gradually tend to the vertical state and slowly deflect. The vertical steel plate moves downward under the action of its own weight to contact the rubber material The high-quality buffer arc block can prevent the steel plate from making a loud noise when it falls and prevent the edge of the steel plate from being bumped. After the buffer arc block is compressed, the steel plate will slide along the tilting racks on both sides and lean against the buffer rod, so that the buffer rod pushes the spring to be compressed, and the buffer rod slides along the tilting rack to make the steel plate in an inclined state. Since the steel plate is heavier as a whole, the compressed flap can be used to transform the steel plate from a state of being in contact with the pushing table to a vertical state, reducing the difficulty of removing the steel plate from the pushing table. At the same time, the buffer arc block is used to buffer the steel plate and place it in the vertical slot plate at an angle, making the transfer of the steel plate safer and more convenient to take the cut steel plate.

[0009] According to the above technical solution, a table surface processing device is arranged on the inner side of the cutting table, and the table surface processing device includes a pressure push plate, a pressure rod, a pressure box push plate, a liquid box, and an air box.

The internal structure of the air box is the same as the internal structure of the liquid tank. A one-way valve is arranged on the top of the liquid tank. When the threaded rod rotates in the opposite direction to reset the sliding frame, the sliding frame is reset through the sliding frame. The movement of the frame drives the pressure push plate to approach the pressure rod on one side of the liquid tank, so that the pressure push plate approaches the pressure rod to control the liquid in the liquid tank to spray out along the external pipe, and a small amount of water is sprayed on the section of the steel plate for cooling the unextinguished sparks and the steel plate. When the sliding frame moves toward the side of the air box, the sliding frame will drive the pressure push plate to push the pressure rod on one side of the air box, and the gas in the air box will be sprayed out through the external pipe, and the extinguished particles and water stains will be blown into the collection box for collection. The operating status of the liquid tank and the air box are controlled respectively by the forward and backward movement of the pressure push plate, so that the cleaning can be reasonably arranged according to the processing steps.

When the steel plate is cut, the bent steel plate is leveled, thereby preventing the bending of the steel plate from affecting the cutting accuracy. The present invention is provided with a push plate, an auxiliary roller, a width limiting plate, a driving motor, a threaded rod, a sliding moment frame, a gear roller shaft, a connecting roller rod, an extension rod, a push rod, and an arc groove rod. The extension rod extends from the connecting roller rod to push the cut steel plate to a specified position, thereby pushing the steel plate to move a long distance without affecting the cutting. At the same time, when the connecting roller rod swings from the rear end to the front end, the debris scattered from the cut steel plate to the push plate is pushed into the groove in the middle of the push plate by the push rod, so as to prevent particles from being scattered to the push plate to avoid affecting the flatness of the steel plate and further affecting the cutting of the steel plate.

The material pushing platform 51 is fixedly connected to the inner side surface of the cutting platform 1, the auxiliary roller 52 is rotatably connected to the inner side of the material pushing platform 51, the width limiting plate 53 is fixedly connected to the surface of the material pushing platform 51, the driving motor 54 is fixedly connected to the inner side of the cutting platform 1, the threaded rod 55 is fixedly connected to the end of the output shaft of the driving motor 54, the sliding frame 56 is threadedly connected to the outer side of the threaded rod 55, and the toothed roller shaft 57 is meshedly connected to the bottom side surface of the sliding frame 56.

When the driving motor 54 rotates, the threaded rod 55 connected to the output shaft will be driven to rotate, and the sliding frame 56 will be driven to slide along the two sides of the square rail through the rotation of the threaded rod 55, so that the gear roller shaft 57 is engaged through the tooth groove on the bottom side of the sliding frame 56, so that the gear roller shaft 57 rotates to drive the connecting roller rod 58 to deflect. During the deflection and movement of the connecting roller rod 58, the connecting roller rod 58 drives the extension rod 59 to slide from one end to the other end along the curved arc groove rod 511 through the side sliding rod, so as to push the steel plate onto the surface of the pushing platform 51, so that the pushing material The steel plate on the table 51 is pushed by an external force and rolled into the inner side of the width limiting plate 53 through the auxiliary roller 52 until the edge of the steel plate passes over the pushing rod 510. Since the pushing rod 510 is pulled by a spring, the pushing rod 510 always fits the pushing table 51 under the action of the spring tension. The pushing rod 510 pushes the steel plate through the deflection of the connecting roller rod 58. During this process, the extension rod 59 slides along the curved arc groove rod 511 through the side sliding rod, which will cause part of the extension rod 59 structure to shrink into the inside of the connecting roller rod 58, and as the connecting roller rod 58 rotates, the pushing rod 510 gradually pushes the steel plate to the bottom of the cutting machine 3 for cutting. A square rail is fixedly connected to the inner side of the bottom end of the cutting table 1, and the square rail is slidably connected to the sliding frame 56.

After the cutting is completed, as the connecting roller rod 58 continues to rotate, the extension rod 59 extends from the connecting roller rod 58 to push the cut steel plate to the specified position, thereby pushing the steel plate to move a long distance without affecting the cutting. At the same time, when the connecting roller rod 58 swings from the rear end to the front end,The push rod 510 pushes the debris scattered on the push plate 51 from the cut steel plate into the groove in the middle of the push plate 51 to prevent the particles from being scattered on the push plate 51 to avoid affecting the flatness of the steel plate and further affecting the cutting of the steel plate.

[0016] Working principle: the cutting machine 3 is driven by the built-in motor to slide along the structure of the cutting frame 2 to cut and cut the plate. When the bidirectional screw 49 is driven to rotate by the built-in motor of the collecting box 7, the rotation of the bidirectional screw 49 will drive the support blocks 48 connected on both sides to rotate, so that the two support blocks 48 are close to or away from each other. When the two support blocks 48 are in a state of approaching each other and sliding along the inner side of the collecting box 7, the support block 48 will drive the inclined slot slider 45 to slide through the connecting rod 47 connected to the side, so that the inclined slot slider 45 slides along the inclined slot on the side of the collecting box 7, and the top pressure roller 46 connected to the inclined slot slider 45 will move upward together, and gradually make the top side surface of the top pressure roller 46 consistent with the top surface of the support block 48, so that the support The block 48 and the top pressure roller 46 together play a supporting role for the steel plate. The support block 48 and the top pressure roller 46 provide support for the steel plate during cutting to prevent the cutting machine 3 from causing damage to objects other than the steel plate or the structure inside the device. At the same time, the movement of the inclined slot slider 45 will drive the connected pressure slide bar 44 to move together, so that the pressure slide bar 44 and the pressure frame slide bar 42 slide against each other, and the pressure slide bar 44 pulls the leveling pressure frame 41 to deflect downward and apply pressure, so that the leveling pressure frame 41 deflects and drives the bottom pressure frame roller 43 to squeeze, and cooperates with the top pressure roller 46 to apply pressure, so that the bent steel plate is pressed and rolled flat by the top pressure roller 46, and the bent steel plate is leveled when the steel plate is cut, so as to prevent the bending of the steel plate from affecting the cutting accuracy; When the driving motor 54 rotates, it will drive the threaded rod 55 connected to the output shaft to rotate, and through the rotation of the threaded rod 55, it will drive the sliding frame 56 to slide along the two sides of the square rail, so that the tooth groove on the bottom side of the sliding frame 56 engages the tooth roller shaft 57, so that the tooth roller shaft 57 rotates and drives the connecting roller rod 58 to deflect. During the deflection and movement of the connecting roller rod 58, the connecting roller rod 58 drives the extension rod 59 to slide from one end to the other along the curved groove rod 511 through the side sliding rod, pushing the steel plate onto the surface of the pushing table 51, so that the steel plate on the pushing table 51 is pushed by the external force through the auxiliary roller 52 and rolled into the inner side of the width limiting plate 53 until the edge of the steel plate passes over the pushing rod 510. Since the pushing rod 510 is pulled by the spring, the pushing rod 510 is always in contact with the pushing table 51 under the action of the spring tension, and the pushing rod 58 is deflected. The rod 510 will push the steel plate. During this process, the extension rod 59 slides along the curved groove rod 511 through the side sliding rod, which will cause part of the extension rod 59 structure to shrink into the inside of the roller rod 58, and as the roller rod 58 rotates, the push rod 510 will gradually push the steel plate to the bottom of the cutting machine 3 for cutting. After the cutting is completed, as the roller rod 58 continues to rotate, the extension rod 59 extends from the roller rod 58 to push the cut steel plate to the specified position, thereby pushing the steel plate to move a long distance without affecting the cutting. At the same time, when the roller rod 58 swings from the rear end to the front end, the debris scattered from the cut steel plate to the pushing table 51 is pushed into the groove in the middle of the pushing table 51 through the pushing rod 510, preventing particles from scattering to the pushing table 51 to avoid affecting the flatness of the steel plate and further affecting the cutting of the steel plate.

[0017] See also Figure 6-Figure 8On the basis of the above embodiment, in another embodiment of the present invention, a buffer device 6 is provided on the rear side of the cutting stand 1, and the buffer device 6 includes a touch pressure rod 61, a pressure arc rod 62, a pressure flap 63, a touch rod pressure block 631, a baffle 64, a vertical groove plate 65, a buffer arc block 66, a tilting frame 67, and a buffer rod 68. The touch pressure rod 61 is fixedly connected to the side of the sliding moment frame 56, the pressure arc rod 62 is fixedly connected to the top of the touch pressure rod 61, the pressure flap 63 is hingedly connected to the bottom surface of the top of the cutting stand 1, and the two touch rod pressure blocks 631 are respectively fixedly connected to the left and right ends of the pressure flap 63, the baffle 64 is fixedly connected to the top of the rear side of the cutting stand 1, and the vertical groove The plate 65 is fixedly connected to the rear side of the cutting platform 1, the buffer arc block 66 is fixedly connected to the inner side of the vertical slot plate 65, the tilting frame 67 is fixedly connected to the rear side of the vertical slot plate 65, and the buffer rod 68 is slidably connected to the side of the tilting frame 67. The cut steel plate is pushed to the slope on the rear side of the pushing platform 51, and passes through the surface of the pushing platform 51 along the slope and is blocked by the pressure flap 63. At this time, the pressure flap 63 first plays the role of buffering the sliding of the steel plate along the inclined surface of the pushing platform 51. Subsequently, in the process of the sliding frame 56 moving from the front end of the inner side of the cutting platform 1 to the rear end, the sliding frame 56 moves to drive the touch rods 61 on both sides to move, so that the touch rods 61 touch the The touch rod pressure blocks 631 on both sides of the pressure flap 63 allow the touch rod pressure blocks 631 to deflect after being compressed. The deflection of the pressure flap 63 will gradually bring the top end closer to the surface of the steel plate, and allow the steel plate to gradually tend to a vertical state and slowly deflect. The vertical steel plate moves downward under the action of its own weight and contacts the rubber buffer arc block 66 to prevent the steel plate from falling and making a loud noise, and to prevent the edge of the steel plate from being bumped. A spring is provided on the rear side of the buffer rod 68, and the front end of the spring is fixedly connected to the buffer rod 68, and the rear end of the spring is fixedly connected to the tilting frame 67. The touch rod pressure block 631 corresponds to the position of the pressure arc rod 62. A torsion spring is provided on the side of the pressure flap 63, and the torsion spring The inner end of the spring is fixedly connected to the pressure flap 63, and the outer end of the torsion spring is fixedly connected to the baffle 64. After the buffer arc block 66 is compressed, the steel plate will slide along the tilting frames 67 on both sides and lean against the buffer rod 68, so that the buffer rod 68 pushes the spring to be compressed, and the buffer rod 68 slides along the tilting frame 67 to put the steel plate in an inclined state. Since the steel plate is heavier as a whole, the pressure flap 63 is used to transform the steel plate from a state of being in contact with the pushing table 51 to a vertical state, thereby reducing the difficulty of removing the steel plate from the pushing table 51. At the same time, the buffer arc block 66 is used to buffer and lower it into the vertical slot plate 65 for tilted placement, making the transfer of the steel plate safer and more convenient to take the cut steel plate.

[0018] A table surface processing device 8 is arranged on the inner side of the cutting table 1, and the table surface processing device 8 includes a pressure push plate 81, a pressure rod 82, a pressure box push plate 83, a liquid tank 84, and an air tank 85. The pressure push plate 81 is fixedly connected to the surface of the sliding frame 56, and the liquid tank 84 is fixedly connected to the inner side of the cutting table 1. The rear side of the top of the liquid tank 84 is fixedly connected to a top fixing support frame, and the rear end of the top fixing support frame is fixedly connected to an air tank 85. The internal structure of the air tank 85 is the same as that of the liquid tank 84. A one-way valve is arranged on the top of the liquid tank 84. When the threaded rod 55 rotates in the opposite direction to reset the sliding frame 56, the pressure push plate 8 is driven by the sliding frame 56 to move. 1 is moved closer to the pressure rod 82 on one side of the liquid tank 84, and the pressure push plate 81 is moved closer to the pressure rod 82 to control the liquid in the liquid tank 84 to spray out along the external pipeline to produce unextinguished sparks and a small amount of water to cool the cross section of the steel plate. When the sliding frame 56 moves toward the side of the air tank 85, the sliding frame 56 will drive the pressure push plate 81 to push the pressure rod 82 on one side of the air tank 85, spray the gas in the air tank 85 through the external pipeline, and blow the extinguished particles and water stains into the collection box 7 for collection. The operating states of the liquid tank 84 and the air tank 85 are respectively controlled by the forward and backward movement of the pressure push plate 81, so that the cleaning can be reasonably arranged according to the processing steps.

[0019] Working principle: the cut steel plate is pushed to the slope on the rear side of the pushing table 51, and passes through the surface of the pushing table 51 along the slope and is blocked by the pressure flap 63. At this time, the pressure flap 63 first plays the role of buffering the sliding of the steel plate along the inclined surface of the pushing table 51. Subsequently, in the process of the sliding frame 56 moving from the front end to the rear end of the inner side of the cutting table 1, the movement of the sliding frame 56 drives the contact pressure rods 61 on both sides to move, so that the contact pressure rods 61 touch the contact rod pressure blocks 631 on both sides of the pressure flap 63, and the contact rod pressure blocks 631 are compressed to deflect the pressure flap 63. The deflection of the pressure flap 63 will make the top end gradually approach the surface of the steel plate, and make the steel plate gradually tend to the vertical state and slowly deflect, tending to the vertical steel plate Under the action of its own weight, the buffer arc block 66 moves downward to contact the rubber material to prevent the steel plate from falling and making a loud noise, and to prevent the edge of the steel plate from being bumped. After the buffer arc block 66 is compressed, the steel plate will slide along the tilting racks 67 on both sides and lean against the buffer rod 68, so that the buffer rod 68 pushes the spring to be compressed, and the buffer rod 68 slides along the tilting rack 67 to make the steel plate in an inclined state. Since the steel plate is heavier as a whole, the compressed flap 63 transforms the steel plate from the state of being in contact with the material pushing table 51 to a vertical state, reducing the difficulty of removing the steel plate from the material pushing table 51. At the same time, the buffer arc block 66 is used to buffer and place it in the vertical slot plate 65, making the transfer of the steel plate safer and more convenient to take the cut steel plate. When the threaded rod 55 rotates in the opposite direction to reset the sliding frame 56, the sliding frame 56 moves to drive the pressure push plate 81 to approach the pressure rod 82 on the side of the liquid tank 84, so that the pressure push plate 81 is close to the pressure rod 82 to control the liquid in the liquid tank 84 to spray out along the external pipeline to produce unextinguished sparks and a small amount of water to cool the cross-section of the steel plate. When the sliding frame 56 moves toward the side of the air tank 85, the sliding frame 56 will drive the pressure push plate 81 to push the pressure rod 82 on the side of the air tank 85, spray the gas in the air tank 85 through the external pipeline, and blow the extinguished particles and water stains into the collection box 7 for collection. The operating states of the liquid tank 84 and the air tank 85 are controlled respectively by the forward and backward movement of the pressure push plate 81, so that the cleaning can be reasonably arranged according to the processing steps.
