Description

Technical Field

[0001] This utility model relates to the field of cutting devices, specifically to a laser sheet metal cutting device. Background Technology

[0002] Laser cutting is a high-precision cutting process that uses a laser beam to cut workpieces. It is commonly used to cut materials such as metal, plastic, wood, and glass, and has the advantages of high speed, high precision, and wide applicability.

[0003] In the prior art, utility model patent application number CN202421777698.3 discloses a laser cutting device, including two symmetrically arranged supports, a first support plate, and a second support plate. A grinding component is provided on one side of each of the first support plates, and a laser cutting component is provided on the top of the second support plate. A clamping component for holding the sheet material is also provided on one side of the second support plate. The clamping component includes a support frame, with a threaded rod rotatably connected to the inner wall of the support frame. The clamping plate and the threaded rod are threaded together. The sheet material is placed between the support frame and the clamping plate, and then the threaded rod is rotated, causing the clamping plate to descend and contact the sheet material, maintaining a certain pressure, thereby completing the clamping of the sheet material.

[0004] However, the aforementioned laser cutting equipment requires manual clamping of the sheet metal each time it cuts, which reduces the cutting efficiency and needs improvement. Utility Model Content

[0005] The purpose of this invention is to provide a laser sheet cutting device that can automatically transport sheet metal to a fixing mechanism for clamping and fixing via a conveyor wheel, thereby solving the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A laser sheet metal cutting device includes a long, rectangular frame on which a laser cutting mechanism is mounted. A support mechanism is located on the frame below the laser cutting mechanism. The support mechanism includes two pallets arranged opposite each other along the width of the frame. The two pallets are driven by an adjustment mechanism to move closer or further apart. Side baffles are fixedly installed on the sides of the two pallets that are further apart, and the side baffles have fixing mechanisms for pressing down the sheet metal. Below the pallets is a mounting frame that moves up and down driven by a lifting assembly. Multiple conveyor wheels are rotatably mounted on the mounting frame, evenly spaced along the length of the frame. The axes of the conveyor wheels extend along the width of the frame. The multiple conveyor wheels are driven to rotate synchronously by a power device. The pallets have pre-drilled holes for the tops of the conveyor wheels to extend out.

[0007] As a further improvement, the frame includes a rectangular frame with a vertically through slot inside. A slide rod extending along the width direction of the frame is fixedly installed in the slot, and a sliding sleeve matching the slide rod is fixedly installed at the bottom of the tray.

[0008] As a further improvement, the upper end of the side baffle extends beyond the top of the support plate.

[0009] As a further improvement, the fixing mechanism includes a support plate fixedly installed on the side baffle, the support plate being located above the corresponding support plate, and a clamping cylinder being installed on the support plate, the piston rod of the clamping cylinder extending downward and fixedly installed with a pressure plate.

[0010] As a further improvement, a bracket is fixedly installed on one of the side baffles, and a detection photoelectric device for detecting when the plate enters the effective range of the pressure plate is fixedly installed on the bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Workers place the sheet material to be cut between the front ends of two pallets, and multiple conveyor wheels transport the sheet material to the bottom of the pressure plate. Then, a clamping cylinder drives the pressure plate to press the sheet material down. Alternatively, the conveyor wheels transport the cut sheet material to the rear ends of the two pallets, and workers can then remove the cut sheet material. This makes loading and unloading the sheet material more convenient and eliminates the need for manual clamping, thereby improving the cutting efficiency of the sheet material. The synchronous extension and retraction of two translation cylinders causes two pallets to move closer or further apart, and the two pallets cause the side baffles on both sides to move closer or further apart, so that plates of different widths can be placed on the pallets between the two side baffles, thus improving versatility.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 6 As shown, the laser sheet cutting device includes a frame 1, which is a long strip extending front to back. The frame specifically includes four support legs 2, and a rectangular frame is fixedly installed on the upper end of the four support legs 2. The frame includes two long side frames 3 arranged opposite each other on the left and right sides, which extend front to back. A horizontally extending short side frame 4 is fixed between the front ends of the two long side frames 3 and between the rear ends of the two long side frames 3 by bolts.

[0017] A laser cutting mechanism is installed on the frame 1. The laser cutting mechanism includes two vertical plates 5 arranged opposite each other on the left and right. A crossbeam 6 is fixedly installed between the upper ends of the two vertical plates 5 by bolts. The bottom of the crossbeam 6 is provided with a horizontally extending slide groove 7. A slide block 8 is slidably installed in the slide groove 7. An adjusting cylinder 9 with a piston rod extending downward is installed at the bottom of the slide block 8 by bolts. A mounting plate is fixedly installed at the lower end of the piston rod of the adjusting cylinder 9 by bolts. A laser cutting head 10 is installed on the mounting plate. The height of the laser cutting head 10 can be adjusted by adjusting the extension and retraction of the adjusting cylinder 9.

[0018] A horizontal adjustment motor 11 is bolted to the upper end of the vertical plate 5 on the right side. The motor shaft of the horizontal adjustment motor 11 extends into the slide groove 7 and is fixedly mounted with a horizontal adjustment screw 12 extending in the same direction as the slide groove 7 via a coupling. The end of the horizontal adjustment screw 12 away from the horizontal adjustment motor 11 is rotatably connected to the inner wall of the slide groove 7 via a bearing. The slide block 8 is threadedly connected to the horizontal adjustment screw 12. The horizontal adjustment motor 11 drives the horizontal adjustment screw 12 to rotate, which in turn drives the slide block 8 to move left and right along the slide groove 7.

[0019] Both long frame members 3 have guide grooves 13 extending along their length at their top. The lower ends of the two vertical plates 5 are slidably installed in the corresponding guide grooves 13. A guide rod 14 extending in the same direction is fixedly installed in the right guide groove 13 by bolts, and the lower end of the right vertical plate 5 is slidably installed on the guide rod 14. A front-to-back adjustment motor 15 is bolted to the outside of the frame. The motor shaft of the front-to-back adjustment motor 15 extends into the left guide groove 13 and is fixedly installed with a front-to-back adjustment screw 16 extending in the same direction as the guide groove 13 by a coupling. The end of the front-to-back adjustment screw 16 away from the front-to-back adjustment motor 15 is rotatably connected to the inner wall of the guide groove 13 by a bearing. The lower end of the left vertical plate 5 is threadedly connected to the front-to-back adjustment screw 16. The front-to-back adjustment motor 15 drives the front-to-back adjustment screw 16 to rotate, which in turn drives the two vertical plates 5 and the crossbeam 6 to move back and forth as a whole, thereby driving the slide 8 to move back and forth. The cutting position of the laser cutting head 10 on the plate 36 is adjusted by moving the slide 8 back and forth and left and right.

[0020] like Figure 3 and Figure 4 As shown, a support mechanism is provided on the frame 1 located below the laser cutting mechanism. The support mechanism includes two support plates 17 arranged horizontally and laterally along the width direction of the frame 1. The support plates 17 are elongated strips extending in the same direction as the frame 1. The two support plates 17 are used to support the bottom of the left and right sides of the plate 36. The inner sides of the two long sidewalls 3 and the two short sidewalls 4 are provided with vertically penetrating through slots 18. The inner walls of the through slots 18 are fixedly installed with slide rods 19 extending horizontally and laterally along the width direction of the frame 1. Two slide rods 19 are arranged opposite each other in front and behind. The bottom of the front and rear ends of the support plate 17 are respectively fixedly installed with sliding sleeves 20 that match the slide rods 19. The sliding sleeves 20 are slidably sleeved on the corresponding slide rods 19, thereby improving the stability of the left and right sliding of the support plate 17.

[0021] Side baffles 21 are fixedly installed on the opposite sides of the two support plates 17 by bolts. The side baffles 21 are located in a vertical plane and are elongated strips extending in the same direction as the support plates 17. The upper end of the side baffles 21 extends out of the top of the support plates 17. The two side baffles 21 are used to limit the left and right edges of the plate 36 to prevent the plate 36 from deviating.

[0022] The two pallets 17 are driven by an adjustment mechanism to move closer or further apart. The adjustment mechanism includes translation cylinders 22, each bolted to the bottom of one of the two long frame plates 3. The piston rods of the two translation cylinders 22 extend towards each other, and connecting seats 23 are bolted to the piston rods of the translation cylinders 22. The connecting seats 23 are welded to or bolted to the bottom of the corresponding pallet 17. The synchronous extension and retraction of the two translation cylinders 22 causes the two pallets 17 to move closer or further apart, and the two pallets 17 cause the side baffles 21 on both sides to move closer or further apart synchronously, so that plates 36 of different widths can be placed on the pallet 17 between the two side baffles 21, thus improving versatility.

[0023] The side baffle 21 is provided with a fixing mechanism for pressing down the plate 36. The fixing mechanism includes a horizontally extending support plate 24 integrally formed in the middle of the upper end of the side baffle 21. The support plate 24 is located above the corresponding support plate 17. A clamping cylinder 25 is bolted to the top of the support plate 24. The piston rod of the clamping cylinder 25 extends downward and is fixedly mounted with a pressure plate 26 by bolts. When the plate 36 moves to the underside of the pressure plate 26, the clamping cylinder 25 extends and drives the pressure plate 26 to press down on the plate 36, so that the plate 36 is fixed between the pressure plate 26 and the support plate 17, preventing the plate 36 from shifting during cutting.

[0024] like Figure 5 and Figure 6 As shown, a mounting frame 27 driven to move up and down by a lifting assembly is provided below the pallet 17. The mounting frame 27 is U-shaped and extends forward and backward. The mounting frame 27 has a horizontally set base plate and two side plates that are set opposite each other on the top of the base plate by bolts. Between the two side plates, there are multiple conveyor wheels 28 that are evenly spaced forward and backward along the length of the frame 1. The axis of the conveyor wheel 28 extends left and right along the width of the frame 1. The left and right ends of the conveyor wheel 28 are respectively coaxially provided with mounting shafts 29. The mounting shafts 29 on both sides are rotatably mounted on the corresponding side plates of the mounting frame 27 by bearings, and the top of the conveyor wheel 28 is higher than the top of the mounting frame 27. The multiple conveyor wheels are driven to rotate synchronously by a power device. The mounting shafts 29 on the same side of the multiple conveyor wheels 28 are connected by a synchronous belt 30 between two adjacent mounting shafts 29. The bottom of the inner cavity of the mounting frame 27 is bolted to a drive motor 31. The motor shaft of the drive motor 31 is connected to one of the mounting shafts 29 by a transmission belt 32, thereby realizing that the drive motor 31 drives the multiple conveyor wheels 28 to rotate synchronously.

[0025] The pallet 17 is provided with a pre-drilled hole 37 for the top of the conveyor wheel 28 to extend out. The lifting assembly specifically includes lifting cylinders 33 located at the front and rear ends of the mounting frame 27. The cylinder body of the lifting cylinder 33 is fixedly mounted to the bottom of the corresponding pallet 17 by bolts, and the piston rod of the lifting cylinder 33 extends downward and is fixedly mounted to the base plate of the mounting frame 27 by bolts. When the lifting cylinder 33 retracts, it drives the mounting frame 27 to move upward, and then the mounting frame 27 drives the top of the conveyor wheel 28 to extend through the corresponding pre-drilled hole 37 to the top of the pallet 17. The conveyor wheel 28 supports the plate 36 placed on the top of the pallet 17, and the rotation of the conveyor wheel 28 drives the plate 36 to move. Conversely, when the lifting cylinder 33 extends, it drives the mounting frame 27 to move downward, and then the mounting frame 27 drives the conveyor wheel 28 to retract completely under the pallet 17, so that the plate 36 falls back onto the pallet 17.

[0026] A bracket 34 is fixedly installed on one of the side baffles 21. The bracket 34 is located behind the pressure plate 26 and is inverted L-shaped. The lower end of the vertical part of the bracket 34 is fixed to the side baffle 21 by bolts. The horizontal part of the bracket 34 extends away from the vertical part to the space between the two support plates 17. The bottom of the horizontal part of the bracket 34 away from the vertical part is screwed with a detection photoelectric sensor 35 for detecting whether the plate 36 has entered the effective range of the pressure plate 26. When the detection photoelectric sensor 35 detects that the plate 36 has been conveyed to the predetermined position by the conveyor wheel 28, the conveyor wheel 28 stops moving the plate 36 so that the pressure plate 26 can accurately press the plate 36 down.

[0027] In practical use, the operator places the sheet material 36 to be cut between the front ends of the two pallets 17. First, the lifting cylinder 33 retracts and drives the top of the conveyor wheel 28 to extend upward above the pallet 17, lifting the sheet material 36 upward. Then, the drive motor 31 drives multiple conveyor wheels 28 to rotate synchronously, conveying the sheet material 36 backward. When the detection photoelectric sensor 35 detects that the sheet material 36 has been conveyed to the predetermined position, the conveyor wheel 28 stops rotating, the lifting cylinder 33 extends and drives the conveyor wheel 28 to retract under the pallet 17, causing the sheet material 36 to fall back onto the pallet 17. The pressing cylinder 25 extends and drives the pressure plate 26 to press down on the sheet material 36, and then the laser cutting head 10 cuts the sheet material 36.

[0028] After the board is cut, the clamping cylinder 25 retracts, causing the pressure plate 26 to lift the board 36 upward. The lifting cylinder 33 retracts again and drives the conveyor wheel 28 to lift the board 36 upward. The cut board 36 is then transported between the rear ends of the two pallets 17 via the conveyor wheel 28. The staff can then remove the cut board 36.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
