Description

Technical Field

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

[0002] When processing sheet metal materials, steel needs to be cut. At present, laser cutting is the most commonly used cutting method. Laser cutting is when the laser beam is irradiated onto the surface of the workpiece. When the workpiece reaches the melting point or boiling point, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting and engraving.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-9A technical solution provided by an embodiment of the present invention is as follows: the laser cutting machine for sheet metal comprises a machine base 1, a material pushing assembly and a transmission assembly, a material storage trough 3 is provided in the machine base 1, a laser cutting assembly 4 for cutting sheet metal parts 2 is provided in the machine base 1, an active roller 9 is rotatably connected in the machine base 1, a support platform is provided in the machine base 1, a plurality of material storage assemblies for placing sheet metal parts 2 are vertically and equidistantly provided in the material storage trough 3, each material storage assembly comprises two material storage plates 27 rotating in the opposite direction, each material storage plate 27 is provided with a reset member for driving the material storage plate 27 to reset to a horizontal state, the material pushing assembly is driven by the rotation of the active roller 9 to push a sheet metal part 2 at the bottom layer in the material storage trough 3 toward the support platform, the transmission assembly is driven by the rotation of the active roller 9 to reversely rotate the two material storage plates 27 of each material storage assembly in the material storage trough 3 from bottom to top, so that the sheet metal parts 2 on the two material storage plates 27 of each material storage assembly fall to the bottom.

[0030] As a preferred technical solution, each reset component includes a second rotating rod 26, a torsion spring 28 and a trigger gear 25. The second rotating rod 26 is rotatably connected to the inner wall of the material storage trough 3, and the torsion spring 28 is sleeved on the second rotating rod 26. The trigger gear 25 is coaxially fixedly connected to one end of the second rotating rod 26, and each material storage plate 27 is sleeved with each second rotating rod 26 in a one-to-one correspondence. Specifically, the transmission assembly causes the two material storage plates 27 of each material storage component in the material storage trough 3 to rotate in reverse from bottom to top, so that the sheet metal parts 2 on the two material storage plates 27 of each material storage component fall to the bottom, and then the corresponding material storage plates 27 are rotated in reverse through the elastic deformation of the torsion spring 28 and reset to the initial horizontal state, so as to provide support force for the subsequent fall of the adjacent upper material storage plates 27.

[0031] As a preferred technical solution, the pushing assembly includes a driven roller 10 and a pushing block 7. The driven roller 10 is rotatably connected in the machine base 1. The active roller 9 and the driven roller 10 are jointly connected by a synchronous belt 8 on their circumferential sides. The pushing block 7 is arranged on the synchronous belt 8. The pushing block 7 abuts against a sheet metal part 2 at the bottom layer in the storage trough 3. Specifically, the active roller 9 and the driven roller 10 rotate, and at the same time, the pushing block 7 is driven to move by the synchronous belt 8. When one side of the pushing block 7 abuts against one side of a sheet metal part 2 at the bottom layer in the storage trough 3, the pushing block 7 pushes the sheet metal part 2 at the bottom layer in the storage trough 3 to move to the support table, so that the laser cutting assembly 4 can perform laser cutting on the sheet metal part 2 later, thereby improving the cutting efficiency and enabling continuous loading. At the same time, the problem of scratches on the surfaces of adjacent sheet metal parts 2 is avoided during the process of pushing out the sheet metal parts 2.

[0032] As a preferred technical solution, the transmission assembly includes two trigger mechanisms, both of which include a guide rod 19 and a rack body 23. The guide rod 19 is vertically arranged in the machine base 1, and the rack body 23 is movably sleeved on the guide rod 19. Each trigger gear 25 close to the rack body 23 is meshed with the rack body 23 in turn. Specifically, a second slide groove 24 is opened in the machine base 1, and the guide rod 19 is vertically arranged in the second slide groove 24. After the sheet metal part 2 at the bottom layer in the material storage trough 3 is pushed to the support platform, the rack body 23 has a linear stroke and a rotational stroke in turn during the upward movement of the guide rod 19. In the linear stroke, the rack body 23 meshes with multiple trigger gears 25 in turn from bottom to top, so that each second rotating rod 26 drives the corresponding material storage plate 27 to rotate downward, so that the sheet metal parts 2 on the two material storage plates 27 of each material storage component fall into the two material storage plates 27 of the adjacent material storage component below in turn.

[0033] As a preferred technical solution, a second protrusion 22 is provided in the rack body 23, and two straight grooves 20 and two second spiral grooves 21 are provided on the guide rod 19. The two straight grooves 20 are arranged parallel to each other, and the two second spiral grooves 21 are arranged between the two straight grooves 20, which are used to connect the head and tail end points of the two straight grooves 20. The two straight grooves 20 and the two second spiral grooves 21 are both slidably matched with the second protrusion 22. Specifically, during the upward movement of the rack body 23, the rack body 23 is vertically moved upward through the cooperation between one of the straight grooves 20 and the second protrusion 22. When the rack body 23 is meshed with the topmost trigger gear 25, the second spiral groove above is used to move the rack body 23 upward. 21 cooperates with the second protrusion 22, and the rack body 23 rotates 180 degrees during the upward movement to prevent the rack body 23 from meshing with the trigger gears 25 during the downward movement of the rack body 23, so that the sheet metal parts 2 on the two material storage plates 27 of each material storage assembly fall to the bottom layer and stack together, affecting the loading of the material. The rack body 23 moves vertically downward through the cooperation of another straight groove 20 and the second protrusion 22, and then rotates 180 degrees again during the downward movement of the rack body 23 through the cooperation between the second spiral groove 21 and the second protrusion 22 below, so that the rack body 23 meshes with the trigger gears 25 during the subsequent upward movement of the rack body 23.

[0034] As a preferred technical solution, both ends of the active roller 9 are provided with a driving assembly for driving the adjacent rack body 23 to slide, and the two driving assemblies include an incomplete bevel gear 11, a bevel gear body 12 meshing with the incomplete bevel gear 11, a first rotating rod 14 and a slider 16. The incomplete bevel gear 11 is coaxially fixedly connected to one end of the active roller 9, the bevel gear body 12 is horizontally rotatably connected to the base 1, the first rotating rod 14 is coaxially fixedly connected to the top of the bevel gear body 12, and the slider 16 is vertically slidably sleeved on the first rotating rod. On the rod 14, the top of the slider 16 abuts against the bottom of the adjacent rack body 23. Specifically, the active roller 9 rotates to drive the incomplete bevel gear 11 to rotate, and through the meshing transmission, the bevel gear body 12 is driven to rotate, thereby causing the first rotating rod 14 to rotate. The rotation of the first rotating rod 14 drives the slider 16 to slide on the first rotating rod 14. The slider 16 provides an upward driving force to drive the rack body 23 to move upward. When the rack body 23 moves downward due to its own gravity, the slider 16 provides an upward supporting force to it.

[0035] As a preferred technical solution, two first spiral grooves 15 connected end to end are symmetrically opened on the first rotating rod 14, and a first protrusion 17 is provided in the slider 16. The two first spiral grooves 15 are slidably matched with the first protrusion 17. Specifically, a first slide groove 18 is vertically opened in the machine base 1, and the first slide groove 18 is communicated with the second slide groove 24. The first rotating rod 14 is rotatably connected in the first slide groove 18. The cross-sectional size of the slider 16 is adapted to the first slide groove 18. The first slide groove 18 limits the circumferential rotation of the slider 16. Through the sliding cooperation between the first protrusion 17 and the two first spiral grooves 15, the rotation action of the first rotating rod 14 drives the slider 16 to perform vertical reciprocating motion.

[0036] As a preferred technical solution, a motor 13 is provided on one side of the machine base 1, and the output end of the motor 13 is coaxially fixedly connected to one end of the active roller 9. Specifically, the motor 13 drives the active roller 9 to rotate, and drives the pushing block 7 to perform intermittent loading through the synchronous belt 8. At the same time, the transmission component is driven by the rotation of the active roller 9 to make the two storage plates 27 of each storage component in the storage trough 3 rotate in reverse from bottom to top, so that the sheet metal parts 2 on the two storage plates 27 of each storage component fall to the bottom, thereby solving the problem of scratching the surface of adjacent sheet metal parts 2 during the process of pushing out the sheet metal parts 2.

[0037] As a preferred technical solution, a guide groove 29 is provided on the machine base 1, and the guide groove 29 is communicated with the material storage trough 3. The push block 7 is slidably connected with the guide groove 29. Specifically, the guide groove 29 is used to guide and limit the moving direction of the push block 7, so that the push block 7 can push the sheet metal part 2 at the bottom layer in the material storage trough 3 toward the support table for subsequent cutting.

[0038] As a preferred technical solution, the support platform includes a support frame 5, on which a plurality of support tooth plates 6 are arranged at equal distances. Specifically, the bottom of the sheet metal part 2 is slidably abutted against each support tooth plate 6, and the waste cut by the laser cutting assembly 4 is passed through the gap between adjacent support tooth plates 6 and then directly falls to the ground through the support frame 5, thereby avoiding the accumulation of waste materials affecting the subsequent cutting effect.

[0039] Working principle: The laser cutting machine for sheet metal places multiple sheet metal parts 2 on two storage plates 27 in each storage component. The motor 13 drives the active roller 9 to rotate, and drives the push block 7 to move through the synchronous belt 8 and the driven roller 10. When one side of the push block 7 abuts against one side of a sheet metal part 2 at the bottom layer in the storage tank 3, the push block 7 pushes the sheet metal part 2 at the bottom layer in the storage tank 3 to move to the support table, which is convenient for the laser cutting component 4 to perform laser cutting on this sheet metal part 2 later, thereby improving the cutting efficiency and enabling continuous feeding. At the same time, it avoids the problem of scratching the surface of adjacent sheet metal parts 2 during the process of pushing out the sheet metal parts 2. During the cutting process of the sheet metal parts 2, the active The roller 9 rotates, driving the incomplete bevel gear 11 to rotate, and through the meshing transmission, the bevel gear body 12 is driven to rotate, thereby causing the first rotating rod 14 to rotate. The rotation of the first rotating rod 14 drives the slider 16 to slide on the first rotating rod 14. The slider 16 provides an upward driving force to drive the rack body 23 to move upward. The rack body 23 meshes with multiple trigger gears 25 from bottom to top, so that each second rotating rod 26 drives the corresponding storage plate 27 to rotate downward, so that the sheet metal parts 2 on the two storage plates 27 of each storage component fall into the two storage plates 27 of the adjacent storage component below in turn, avoiding multiple sheet metal parts 2 from being stacked together and affecting the loading efficiency.

[0040] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
