Description

Technical Field

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

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

[0003] The prior art also proposes some solutions: for example, a patent with publication number CN115415597A discloses a metal sheet cutting machine, in which a driving mechanism is turned on to make it contact with a guide mechanism when it slides. When the guide mechanism contacts the sheet, it is convenient to guide it when the sheet is displaced; the contact 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 inside the contact mechanism, and the limiting mechanism is released to fix the sheet when the fixing mechanism is reset; the control switch of the cutting mechanism is turned on, so that it is convenient to cut the sheet when it slides inside the main mechanism, thereby helping to improve 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 operating 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.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 10 As shown, the present invention provides a technical solution: a metal plate cutting device, comprising a workbench 1, characterized in that: two cutting tables 2 are arranged on the top of the workbench 1, a metal plate 3 is placed above the cutting table 2, a cutting blade 4 is arranged directly above the metal plate 3, mounting frames 8 are fixedly installed on both sides of the workbench 1, a fixed table 9 is fixedly connected between the two mounting frames 8, a hydraulic cylinder 5 is fixedly installed on the top of the fixed table 9, the output end of the hydraulic cylinder 5 is fixedly connected to the top of the cutting blade 4, connecting rods 6 are fixedly connected on both sides of the cutting blade 4, one end of the connecting rod 6 is fixedly connected with an inner slide block 7, the two inner slide blocks 7 are respectively slidably connected and adapted to the two fixed tables 9, lifting components are arranged on both sides of the cutting blade 4, the lifting components are used to drive the two cutting tables 2 to tilt, a vibration component is arranged inside the lifting component, the vibration component is used to vibrate the cutting table 2 during the tilting process, and an external positioning component is arranged above the cutting table 2.

[0024] 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, and position the metal sheet 3 above the cutting table 2 by means of an external positioning component to avoid the metal sheet 3 from being offset during cutting. After positioning, start the hydraulic cylinder 5, and its output end can drive the cutting blade 4 to descend to cut the metal sheet 3, and when the cutting blade 4 descends, the lifting component 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, respectively. The external positioning component is canceled to position the sheet. When the cutting blade 4 is driven by the hydraulic cylinder 5 to rise and reset, the lifting component rises and can drive one end of the two cutting tables 2 to rise. When one end of the cutting table 2 rises, since the other end cannot rise, the two cutting tables 2 will gradually tilt, accompanied by As the inclination angle of the two cutting tables 2 becomes larger and larger, the two cut metal plates 3 above the two cutting tables 2 will slide out from one side of the cutting table 2 respectively, so that the cut plates can be collected and processed, and 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 together. In the process of the jacking component driving the cutting table 2 to tilt, the vibration component can make the cutting table 2 vibrate continuously during the tilting process. Through the above embodiment, after cutting, the jacking component 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, and 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.

[0025] 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 the multiple external rods 10 are hinged with inner sliding blocks 12. A plurality of open sliding seats 11 are fixedly installed on the top of the workbench 1, and the inner wall of each open sliding seat 11 is slidably connected and adapted to the outer wall of the inner sliding block 12. Both sides of the other ends of the two cutting tables 2 are fixedly connected with bending plates 17, and the bottoms of the multiple bending plates 17 are fixedly connected with bottom plates 18.

[0026] During operation: During the cutting process, the lifting assembly will gradually descend to the bottom of the bottom plate 18. When the lifting assembly rises, it can lift the bottom 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 12 to slide inside the open slide 11. Under the action of the inner slider 12 and the open 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 the higher the lifting assembly rises, the longer the inner slider 12 slides inside the open slide 11, and the greater the tilt angle, thereby achieving the effect that the plate and debris can naturally slide out under the action of gravity generated by the tilt.

[0027] like Figures 5 to 7 As shown, the jacking assembly includes two vertical plate platforms 22, and the two vertical plate platforms 22 are respectively fixedly connected to the top of the two connecting rods 6, and both sides of the vertical plate platforms 22 are fixedly connected with hinge seats 23, the inner walls of the two vertical plate platforms 22 are hinged with hinge shafts 28, the outer walls of the two hinge shafts 28 are fixedly connected with hinged connecting rods 24, the tops of the two hinged connecting rods 24 are fixedly connected with horizontal plate platforms 25, and angle springs 26 are fixedly connected between the inner sides of the two hinged connecting rods 24 and the two sides of the vertical plate platforms 22, and a damping rod 27 is arranged inside the angle spring 26, and the damping rod 27 is fixedly installed between the vertical plate platforms 22 and the hinged connecting rods 24.

[0028] When working: when the cutting blade 4 descends for cutting, it will drive the vertical plate platform 22 to descend, and the vertical plate platform 22 will drive the horizontal plate platform 25 to descend through the hinge connecting rod 24. The two horizontal plate platforms 25 will pass through the two bending plates 17 during the descending process. When the two horizontal plate platforms 25 contact the inner sides of the two bending plates 17, they will be 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 compression and also squeeze the angle spring 26. When the two horizontal plate platforms 25 descend to the bottom of the bottom plate 18, under the action of the angle spring 26, the two horizontal plate platforms 25 can expand outwards for reset. At this time, the top surface of the horizontal plate platform 25 and the bottom surface of the bottom plate 18 remain in contact with each other. Therefore, when the vertical plate platform 22 and the horizontal plate platform 25 are ascending, the horizontal plate platform 25 can support the bottom plate 18 to ascend, thereby making one end of the two cutting tables 2 rise, achieving a tilting effect.

[0029] As 6 to Figure 7 As shown, the inner walls of the two hinged seats 23 are fixedly connected with limit rods 29, the outer sides of the two hinged connecting rods 24 are fixedly connected with return rods 30, and an extrusion assembly is provided on one side of the return rods 30, which is used to make the two return rods 30 close to each other.

[0030] 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 connecting rod 24 and the hinge seat 23. When the horizontal platform 25 is squeezed by the bending plate 17, the hinge connecting rod 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 limited 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, and the two horizontal platforms 25 can always remain motionless when rising. Through the extrusion component, when the horizontal platform 25 rises and makes the cutting table 2 tilt to a sufficient angle, the plate and debris have slipped out, and 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, so that the horizontal platform 25 and the bottom plate 18 are out of contact, and the rising end of the cutting table 2 can also be lowered to complete the reset.

[0031] 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 all provided with angled grooves 37 , and the angled grooves 37 are slidably connected and matched with the return rod 30 .

[0032] During operation: when the two hinged connecting rods 24 drive the return rod 30 to rise, the angle plate 36 will be close to the return rod 30, and when the return rod 30 rises, it will enter the inside of the angle groove 37. Under the action of the angle groove 37, the two return rods 30 will enter the curved part of the angle groove 37 and be squeezed when continuing to rise. 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 cross plate 25 and the bottom plate 18, and achieving the effect of resetting the cutting table 2.

[0033] 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, a plurality of inner sliding grooves 31 are provided on the inner wall of the top surface of the horizontal platform 25, and a lifting block 33 is provided on the inner wall of each inner sliding groove 31. The plurality of lifting blocks 33 are fixedly connected to the outer wall of the rotating rod 32, and a gear 34 is fixedly connected to one end of the lifting block 33. A plurality of fitting grooves 35 are provided on the bottom surface of each base plate 18, and the plurality of fitting grooves 35 correspond to the plurality of inner sliding grooves 31. A rack assembly for driving the gear 34 to rotate is provided on one side of the gear 34.

[0034] 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 omissions, thereby further improving the effect of processing the debris on the cutting table 2.

[0035] like Figures 9 and 10 As shown, the rack assembly includes a rack plate 38, a plurality of electric sliders 40 are fixedly mounted on the top of the workbench 1, a mounting seat 39 is slidably connected to the inner wall of the electric slider 40, the top of the mounting seat 39 is fixedly connected to the rack plate 38, the teeth of the rack plate 38 are meshed with the teeth of the gear 34, and a plurality of angle plates 36 are fixedly mounted on one side of the plurality of rack plates 38 respectively.

[0036] 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 mesh with the rack plate 38. Similarly, there is no squeezing relationship between the angle 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 to achieve the effect of vibration. The return rod 30 can also enter the angle groove 37 and slide along the inner wall of the angle groove 37.

[0037] like Figures 2 to 3 As shown, one side of the multiple inner sliding blocks 12 is fixedly connected with a plug rod 13, the outer wall of the plug rod 13 is plugged into the inner wall of the open sliding seat 11, and a return spring 14 is arranged on the outside of the plug rod 13. The two ends of the return spring 14 are respectively fixedly connected to the side surface of the inner sliding block 12 and the inner side surface of the open sliding seat 11, one end of the plug rod 13 is fixedly connected to a limiting block 16, and the sides of the two open sliding seats 11 are provided with side sliding grooves 15, and the external connecting rod 10 and the side sliding grooves 15 are movably connected and adapted to each other.

[0038] During operation: when the cutting table 2 is reset after being tilted, 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 absorbing the cutting table 2. The side slide groove 15 is set to limit the internal movable range 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.

[0039] 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 a bonding ball 20 is fixedly connected to the top of each of the cylindrical frames 19. 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 bonded to the bottom of the cutting table 2.

[0040] 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 maintains 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.

[0041] like Figures 4 to 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.

[0042] 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.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
