Description

Technical Field

[0001] The invention belongs to the technical field of plate cutting, and particularly relates to a metal plate cutting device. Background Art

[0002] The working principle of sheet metal cutting equipment is mainly based on different cutting technologies such as shearing, sawing, laser cutting, and plasma cutting. Among them, shearing is the most common cutting method. It uses two blades to apply shear force to the metal sheet. When the shear force exceeds the shear strength of the material, the sheet is severed. Other cutting methods use energy sources such as lasers and plasma to locally heat or melt the metal sheet to achieve cutting.

[0003] The existing technology also proposes some solutions: for example, a patent with publication number CN115415597A discloses a metal plate cutting machine, in which the driving mechanism is turned on to make it contact with the guide mechanism when it slides. When the guide mechanism contacts the plate, it is convenient to guide it when the plate is displaced; the interference mechanism is stepped on to drive the fixing mechanism to rotate, so that the limiting mechanism is convenient to limit it when it is engaged with the inside of the interference mechanism, and the limiting mechanism is released to fix the plate when the fixing mechanism is reset; the control switch of the cutting mechanism is turned on, so that it is convenient to cut the plate when it slides inside the main mechanism, thereby improving the use effect of the cutting mechanism.

[0004] After the existing device completes the cutting of the plate, the plate needs to be taken out and collected by starting an additional unloading system. The additional unloading system requires more operation steps and time to complete the collection of the plate, which reduces the overall production efficiency. After the plate is cut and unloaded, a part of the cut debris will remain on the cutting table. The debris will cause the next plate to be placed unevenly and affect the cutting accuracy. The debris needs to be cleaned up additionally, further increasing the workload.

[0005] To this end, the present invention provides a metal sheet cutting device. Summary of the Invention

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1 to 10 As shown, the present invention provides a technical solution: a metal sheet cutting equipment, including a workbench 1, characterized in that: two cutting tables 2 are provided on the top of the workbench 1, a metal sheet 3 is placed above the cutting table 2, and a cutting blade 4 is provided directly above the metal sheet 3. Mounting brackets 8 are fixedly installed on both sides of the workbench 1, a fixed table 9 is fixedly connected between the two mounting brackets 8, a cylinder 5 is fixedly installed on the top of the fixed table 9, the output end of the cylinder 5 is fixedly connected to the top of the cutting blade 4, both sides of the cutting blade 4 are fixedly connected with a connecting rod 6, one end of the connecting rod 6 is fixedly connected with an inner slider 7, the two inner sliders 7 are respectively slidably connected and adapted to the two fixed tables 9, and jacking components are provided on both sides of the cutting blade 4, the jacking components are used to drive the two cutting tables 2 to tilt, and a vibration component is provided inside the jacking component, the vibration component is used to vibrate the cutting table 2 during the tilting process, and an external positioning component is provided above the cutting table 2.

[0034] During operation: place the metal sheet 3 to be cut directly above the two cutting tables 2, and make the cutting line of the metal sheet 3 located between the gaps of the two cutting tables 2. Position the metal sheet 3 above the cutting table 2 through an external positioning assembly to avoid positional displacement of the metal sheet 3 during cutting. After positioning, start the cylinder 5 so that its output end can drive the cutting blade 4 to descend to cut the metal sheet 3. When the cutting blade 4 descends, the jacking assembly can also descend. When the cutting is completed, the metal sheet 3 will be divided into two and located directly above the two cutting tables 2. The external positioning assembly is canceled to position the sheet. When the cutting blade 4 is driven by the cylinder 5 to rise and reset, the jacking assembly rises and can drive one end of the two cutting tables 2 to rise. When one end of the cutting table 2 rises, the other end cannot rise, so the two cutting tables 2 will gradually tilt, accompanied by the two As the cutting table 2 tilts at an increasingly larger angle, the two cut metal plates 3 above the two cutting tables 2 will slide out from one side of the cutting table 2 respectively, thereby collecting and processing the cut plates. In the process of the cutting table 2 tilting and causing the plates to fall out, the cutting debris remaining above the cutting table 2 will also slide out. In the process of the jacking assembly driving the cutting table 2 to tilt, the vibration assembly can cause the cutting table 2 to vibrate continuously during the tilting process. Through the above embodiment, after cutting, the jacking assembly drives the two cutting tables 2 to gradually tilt. During the tilting process, the plates and debris naturally slide down under the action of gravity, and the cutting table 2 can also vibrate during the tilting process, further ensuring that the debris is removed from the table more quickly and thoroughly, reducing residue and accumulation. The collection of the plates and the processing of the debris can be carried out during the process of the cutting blade 4 rising and resetting, making the cutting process smoother and more efficient.

[0035] like Figures 2 to 3 As shown, both sides of one end of the two cutting tables 2 are fixedly connected with external rods 10, and the outer walls of multiple external rods 10 are hinged with inner sliders 12. Multiple open slides 11 are fixedly installed on the top of the workbench 1, and the inner wall of each open slide 11 is slidably connected to the outer wall of the inner slider 12 and adapts to each other. Both sides of the other end of the two cutting tables 2 are fixedly connected with bending plates 17, and the bottoms of multiple bending plates 17 are fixedly connected with base plates 18.

[0036] During operation: During the cutting process, the lifting assembly will gradually descend to the bottom of the base plate 18. When the lifting assembly rises, it can lift the base plate 18 upward, and when one end of the cutting table 2 is subjected to an upward support force, the other end of the cutting table 2 will cause the inner slider 2 12 to slide inside the opening slide 11. Under the action of the inner slider 2 12 and the opening slide 11, the other end of the cutting table 2 will not rise. Therefore, with the cooperation of the two, the two cutting tables 2 can gradually tilt, and as the lifting assembly rises higher, the inner slider 2 12 slides more inside the opening slide 11, and the tilt angle becomes larger, thereby achieving the effect that the plate and debris can naturally slide out under the action of gravity generated by the tilt.

[0037] like Figures 5 to 7 As shown, the jacking assembly includes two vertical platforms 22, and the two vertical platforms 22 are respectively fixedly connected to the bottom of the two connecting rods 6. Both sides of the vertical platforms 22 are fixedly connected with hinged seats 23, the inner walls of the two vertical platforms 22 are hinged with hinged shafts 28, the outer walls of the two hinged shafts 28 are fixedly connected with hinged links 24, the tops of the two hinged links 24 are fixedly connected with horizontal platforms 25, and angle springs 26 are fixedly connected between the inner sides of the two hinged links 24 and the two sides of the vertical platforms 22. A damping rod 27 is arranged inside the angle spring 26, and the damping rod 27 is fixedly installed between the vertical platforms 22 and the hinged links 24.

[0038] When the cutting blade 4 is lowered for cutting, the vertical plate platform 22 is driven to lower, and the vertical plate platform 22 drives the horizontal plate platform 25 to lower through the hinge connecting rod 24. During the lowering process, the two horizontal plate platforms 25 pass through the two bent plates 17. When the two horizontal plate platforms 25 contact the inner sides of the two bent plates 17, they are squeezed by the bending plates 17, so that the hinge connecting rod 24 and the hinge seat 23 are hinged and rotated, and the two horizontal plate platforms 25 are close to each other for squeezing and also squeezing the angle spring 26. When the two horizontal plate platforms 25 are lowered to the bottom of the bottom plate 18, the two horizontal plate platforms 25 can expand outwards to reset under the action of the angle spring 26. At this time, the top surface of the horizontal plate platform 25 remains in contact with the bottom surface of the bottom plate 18. Therefore, when the vertical plate platform 22 and the horizontal plate platform 25 are raised, the horizontal plate platform 25 can support the bottom plate 18 to rise, thereby making one end of the two cutting tables 2 rise, achieving a tilting effect.

[0039] Such as 6 to Figure 7 As shown, the inner walls of the two hinged seats 23 are fixedly connected with the limiting rod 29, and the outer sides of the two hinged links 24 are fixedly connected with the return rod 30. An extrusion assembly is provided on one side of the return rod 30, and the extrusion assembly is used to make the two return rods 30 close to each other.

[0040] During operation: by setting a limit rod 29 on the inner wall of the hinge seat 23, the limit rod 29 limits the hinge relationship between the hinge link 24 and the hinge seat 23. When the horizontal platform 25 is squeezed by the bending plate 17, the hinge link 24 can be hinged and rotated with the hinge seat 23, so that the two horizontal platforms 25 approach each other and smoothly descend through the gap formed between the two bending plates 17. When the top of the horizontal platform 25 is in contact with the bottom surface of the bottom plate 18 and supports the bottom plate 18 to rise, the horizontal platform 25 is restricted by the limit rod 29. The upward supporting force will not cause the hinged relationship between the hinged connecting rod 24 and the hinged seat 23 to be hinged. The two horizontal platforms 25 can always remain motionless when rising. Through the provided extrusion component, when the horizontal platform 25 rises and the cutting table 2 is tilted to a sufficient angle, the plate and debris have slipped out. The extrusion component will make the two return rods 30 approach each other and make the two horizontal platforms 25 approach each other and shrink. Therefore, the horizontal platform 25 and the base plate 18 are separated from the fitting relationship, and the rising end of the cutting table 2 can also be lowered to complete the reset.

[0041] like Figures 9 and 10 As shown, the extrusion assembly includes a plurality of angled plates 36 , and the inner walls of the plurality of angled plates 36 are each provided with an angled groove 37 , and the angled groove 37 is slidably connected and adapted to the return rod 30 .

[0042] During operation: when the two hinged links 24 drive the return rod 30 to rise, the angled plate 36 will be close to the return rod 30, and when the return rod 30 rises, it will enter the inside of the angled groove 37. Under the action of the angled groove 37, the two return rods 30 will enter the curved part of the angled groove 37 as they continue to rise and be squeezed. The two return rods 30 will slide close to each other due to the squeezing force, thereby achieving the effect of breaking the fitting relationship between the horizontal plate 25 and the bottom plate 18, and achieving the effect of resetting the cutting table 2.

[0043] like Figures 7 and 8 As shown, the vibration assembly includes a rotating rod 32, the outer wall of the rotating rod 32 is rotatably connected to the inner wall of the horizontal platform 25, and a plurality of inner sliding grooves 31 are provided on the inner wall of the top surface of the horizontal platform 25. The inner wall of each inner sliding groove 31 is provided with a lifting block 33, and the plurality of lifting blocks 33 are fixedly connected to the outer wall of the rotating rod 32. One end of the rotating rod 32 is fixedly connected to a gear 34. The bottom surface of each base plate 18 is provided with a plurality of fitting grooves 35, and the plurality of fitting grooves 35 correspond to the plurality of inner sliding grooves 31. A rack assembly is provided on one side of the gear 34 for driving the gear 34 to rotate.

[0044] During operation: when the horizontal plate 25 is attached to the bottom of the base plate 18, each lifting block 33 is respectively located between the inner slide groove 31 and the fitting groove 35. When the horizontal plate 25 supports the base plate 18 and drives the cutting table 2 to tilt, the gear 34 can continuously rotate through the rack assembly. When the gear 34 rotates, it will drive multiple lifting blocks 33 to rotate through the rotating rod 32. The lifting blocks 33 can continuously lift and lower the base plate 18 during continuous rotation, thereby achieving the effect of continuous vibration of the cutting table 2 during the tilting process. During the vibration process, the debris remaining on the upper surface of the cutting table 2 can slide out better to avoid omission, thereby further improving the effect of processing the debris on the cutting table 2.

[0045] like Figures 9 and 10 As shown, the rack assembly includes a rack plate 38, a plurality of electric sliders 40 are fixedly installed on the top of the workbench 1, the inner wall of the electric slider 40 is slidably connected to a mounting seat 39, the top of each mounting seat 39 is fixedly connected to a rack plate 38, the teeth of the rack plate 38 are engaged with the teeth of the gear 34, and a plurality of angle plates 36 are respectively fixedly installed on one side of the plurality of rack plates 38.

[0046] During operation: In the initial state, when the horizontal platform 25 descends, the mounting seat 39 slides to one end inside the electric slider 40. At this time, when the gear 34 descends, it will not engage with the rack plate 38. Similarly, there is no squeezing relationship between the angled plate 36 and the return rod 30. When the horizontal platform 25 rises, the mounting seat 39 can slide to the other end inside the electric slider 40. At this time, during the rising process of the horizontal platform 25, the gear 34 can mesh with the rack plate 38 and cause the gear 34 to rotate, achieving the effect of vibration. The return rod 30 can also enter the angled groove 37 and slide along the inner wall of the angled groove 37.

[0047] like Figures 2 to 3 As shown, one side of multiple inner sliders 12 is fixedly connected with a plug-in rod 13, the outer wall of the plug-in rod 13 is plugged into the inner wall of the open slide 11, and a return spring 14 is provided on the outside of the plug-in rod 13. The two ends of the return spring 14 are respectively fixedly connected to the side of the inner slider 12 and the inner side of the open slide 11. One end of the plug-in rod 13 is fixedly connected to the limiting block 16. The sides of the two open slides 11 are provided with side sliding grooves 15. The external rod 10 and the side sliding grooves 15 are movably connected and adapted.

[0048] During operation: When the cutting table 2 is reset after tilting, the inner slider 12 will slide to the initial position inside the open slide 11. Under the action of the reset spring 14 and the connecting rod 13, no large noise will be generated during the process of the cutting table 2 being reset from the tilted state to the flat state. The connecting rod 13 and the reset spring 14 play a role in shock absorption of the cutting table 2. The side slide groove 15 is provided to limit the internal range of movement of the inner slider 12 to avoid the generation of large pressure during cutting, which may cause the two cutting tables 2 to shift in position.

[0049] like Figures 2 to 3 As shown, a plurality of cylindrical frames 19 are symmetrically fixedly connected to the top of the workbench 1, and the tops of the plurality of cylindrical frames 19 are fixedly connected to bonding balls 20. The plurality of cylindrical frames 19 are arranged at the bottom of the cutting table 2 near one end of the bending plate 17, and the tops of the plurality of bonding balls 20 are all bonded to the bottom of the cutting table 2.

[0050] During operation: the cylindrical frame 19 and the bonding ball 20 are provided to support the bottom of the cutting table 2 close to the bending plate 17, so that when the metal plate 3 is placed on the cutting table 2 for cutting, the cutting table 2 always remains in a flat state under the huge pressure generated by the cutting, and the metal plate 3 can stably complete the cutting work above the cutting table 2.

[0051] like Figures 4 and 5 As shown, the outer walls of both sides of the cutting blade 4 are symmetrically fixedly connected with extrusion blocks 21, and the two extrusion blocks 21 and the cutting blade 4 are in a V shape. The maximum width between the two extrusion blocks 21 is the same as the distance between the two cutting tables 2. Collection boxes 41 are symmetrically arranged on the top of the two workbenches 1, and the collection box 41 is located directly below the cutting table 2.

[0052] During operation: by providing an extrusion block 21, after the cutting blade 4 descends to cut and divide the metal plate 3 into two, the extrusion block 21 can descend along the cutting surface of the metal plate 3, and can push the two plates when descending, so that one side of the two plates is flush with one side of the cutting table 2, respectively, to avoid the small gap between the two plates affecting the tilting process of the two cutting tables 2, and the collection box 41 is used to collect the cut plates in a centralized manner.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
