Description

Technical Field

[0001] The invention relates to the technical field of metal sheet processing, in particular to a continuous metal sheet processing laser cutting device. Background Art

[0002] Laser cutting utilizes a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces, and some metal plates need to be processed by laser cutting. When existing metal plates are laser cut into patterns, scraps and debris will be generated.

Through the rotation of the rotary drive 9, each power rod 6 can be driven to rotate through several gears 5 and chains 10, thereby driving each The conveying rollers 12 rotate to convey the metal plate, and small blocks 34 are fixedly installed on the left and right sides of each bottom bar b22, and a trapezoidal block 35 is fixedly installed on the lower side of each small block 34. A plurality of vertical slots 39 are provided on the left and right inner walls of the square groove 11, and each small block 34 is movably connected with each vertical slot 39. Two slide slots 38 are provided in the workbench 1, and the two slide slots 38 are movably connected with each vertical slot 39, respectively. Slide bars 33 are movably connected in the two slide slots 38, and the front sides of the two slide bars 33 are fixedly installed with inclined blocks 30, and the lower sides of the two inclined blocks 30 are fixedly installed with long strips 28, and the sides of the two long strips 28 close to each other are fixedly installed with connecting blocks 41, and push plates 29 are fixedly installed on the two connecting blocks 41, and the upper sides of the push plates 29 are fixedly installed with movable plates 16.The left and right inner walls of the square groove 11 are provided with grooves 36, the movable plate 16 is movably connected with the two grooves 36, the lower inner walls of the two slide grooves 38 are provided with long grooves 37, the two long strips 28 are movably connected with the two long grooves 37, the inner walls of the two long grooves 37 close to each other are provided with connecting grooves 40, and the two connecting blocks 41 are movably connected with the two connecting grooves 40, respectively. After the metal plate is transported to the bottom of the laser cutting mechanism 15, the movable plate 16 is moved forward, so that the two long strips 28 can be moved forward, so that the inclined block 30 can be moved forward. Each trapezoidal block 35 is squeezed to move upward, thereby driving the bottom bar b22 to move upward, driving the triangular block 27 on the bottom bar b22 to move upward, and the metal plate can be lifted upward, and then the triangular block 27 on the bottom bar a23 is driven by the cylinder 24 to move upward to hold the metal plate, so that the metal plate can be moved upward to fit the upper wall of the L-shaped bar 2 for fixation, and then the cutting process can be carried out. After cutting, the bottom bar a23 moves downward to discharge the debris and scraps, and then the moving plate 16 is moved forward, so that the moving plate 16 is under the metal plate. At the same time, as the slide bar 33 moves backward, the bottom bar b22 will move downward, and then the next metal plate will be transported, which can drive the cut metal plate to move forward, and the cut part will fall through the square groove 11, which is convenient for the user to take out the cut metal plate. The rear side of the movable plate 16 is fixedly installed with a protrusion 31, and the rear side of each protrusion 31 is fixedly installed with a triangular plate 32. Each triangular plate 32 is staggered with a plurality of triangular blocks 27 on the trapezoidal bar 26. The protrusion 31 can move backward with the movable plate 16, thereby driving the triangular blocks 27 to move backward. The plate 32 moves backward, and the bottom bar b22 moves downward to lift the cut metal plate from the cut metal plate, thereby preventing the cut metal plate from falling off the metal plate. A support frame 17 is fixedly installed on the support leg 3, and a collection box 18 is movably connected to the support frame 17. The collection box 18 is arranged below the square slot 11, and drives the cut metal plate to move forward by conveying the next metal plate, so that the cut part falls through the square slot 11, and the collection box 18 can be used to collect the cut metal plate from the metal plate.

[0023] When in use, the first step is: by placing the metal plate to be cut on the conveyor roller 12, the conveyor roller 12 can convey the metal plate to the bottom of the laser cutting mechanism 15 for cutting. The scraps generated when the metal plate is cut fall onto the bottom bar a23 and the bottom bar b22. When the metal plate is cut, the two lifting bars 25 can be driven downward by a number of cylinders 24, thereby driving each bottom bar a23 to move downward. A gap will be generated between the bottom bar a23 and the bottom bar b22, so that the debris and scraps can slide through the gap. After the debris and scraps are discharged, the bottom bar a23 can be driven upward by the cylinder, so that the triangular block 27 can continue to be used to hold up the next arriving metal plate for further cutting.

[0024] Step 2: The friction force can be reduced by rotating the column 19, thereby preventing the metal plate from moving forward smoothly due to excessive friction force. At the same time, the limiting strip 14 and the inclined strip 13 can be used to continue guiding the metal plate.

[0025] Step 3: The rotation of the rotary drive 9 can drive each power rod 6 to rotate through a plurality of gears 5 and chains 10, thereby driving each conveying roller 12 to rotate and convey the metal plate.

[0026] Step 4: After the metal plate is conveyed to the bottom of the laser cutting mechanism 15, the movable plate 16 is moved forward, so that the two long strips 28 can be driven forward, so that the inclined block 30 can be driven forward, and each trapezoidal block 35 can be squeezed to move upward, so that the bottom bar b22 can be driven to move upward, and the triangular block 27 on the bottom bar b22 can be driven upward, so that the metal plate can be lifted up, and then the triangular block 27 on the bottom bar a23 is driven by the cylinder 24 to move upward to support the metal plate, so that the metal plate can be moved upward to fit the upper wall of the L-shaped bar 2 for fixation, and then the cutting process can be carried out. After the cutting, the bottom bar a23 moves downward to discharge the debris and scraps, and then the movable plate 16 is moved forward again, so that the movable plate 16 is under the metal plate. At the same time, as the slide bar 33 moves backward, the bottom bar b22 will move downward, and then the next metal plate can be conveyed, which can drive the cut metal plate to move forward, and the cut part will fall through the square groove 11, which can facilitate the user to take out the cut metal plate.

[0027] Step 5: The protrusion 31 can move backward with the movable plate 16, thereby driving the triangular plate 32 to move backward. When the bottom bar b22 moves downward, it loses the support for the cut metal plate on the cut metal plate, thereby preventing the cut metal plate from falling off.

[0028] Step 6: The cut metal plate is driven forward by conveying the next metal plate, so that the cut part falls through the square groove 11, and then the cut metal plate on the metal plate can be collected by the collection box 18.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
