Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting equipment technology, and in particular to an energy-saving, automated, and precise metal sheet cutting device. Background Technology

[0002] In automated metal sheet cutting processes, metal sheets of different materials such as carbon steel, stainless steel, aluminum alloy, and copper have a wide thickness range, with the commonly processed sheet thickness ranging from 0.5mm to 22mm. The mechanical properties of soft and hard materials differ significantly. Existing automated cutting equipment has shortcomings in its sheet clamping and bottom support structures, making it difficult to ensure the stability of sheet positioning throughout the entire cutting process. Existing technologies use a fixed table to rigidly support the bottom of the metal sheet. Before cutting, the sheet edges are held by side clamps and an integrated top clamping frame, leaving the middle of the sheet suspended and subjected to force. During cutting, the middle of the sheet deforms and warps slightly, directly causing slanted cuts and dimensional deviations. Furthermore, existing top clamping mechanisms are mostly single, constant-pressure structures that cannot switch clamping modes based on sheet thickness and material hardness. For thin, soft metal sheets (0.5mm-3mm), rigid high-pressure clamping easily causes dents, surface deformation, and scratches. For thicker, harder metal sheets (over 3mm), low-pressure flexible clamping provides insufficient friction, causing the sheet to slip and shift after cutting. This results in extremely poor adaptability and versatility. More importantly, existing clamping structures only apply pressure synchronously throughout the cutting process. When cutting a portion of the metal sheet, the remaining unprocessed material at one end loses clamping support, causing lateral displacement due to cutting stress and other factors, affecting the yield rate of the cut metal sheet. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an energy-saving, automated, and precise metal sheet cutting device. While cutting the metal sheet, this invention can adjust the clamping force on the top surface of the metal sheet according to the thickness of the sheet, avoiding damage to the sheet surface. Furthermore, it can effectively prevent lateral displacement of the unprocessed sheet during cutting, thereby improving the yield rate of sheet cutting.

[0004] This invention is achieved through the following technical solution: This invention discloses an energy-saving, automated, and precise metal sheet cutting device, comprising a horizontally arranged base plate, a cutting platform horizontally positioned on the top of the base plate, and a longitudinally penetrating cutting groove on one side of the top of the cutting platform; a floating clamping and anti-deviation device on the top of the cutting platform, which provides multi-point floating clamping force to the bottom of the metal sheet; a cutting component capable of cutting the metal sheet on one side of the cutting groove; a sheet clamping and lateral movement device at the lower part of the cutting platform capable of clamping the four corners of the metal sheet and moving the metal sheet laterally to adjust the cutting position; and a top clamping adjustment device directly above the cutting platform capable of providing adjustable clamping force to the top of the metal sheet during cutting.

[0005] Furthermore, the floating clamping anti-deviation device includes several rectangular mounting slots evenly distributed on the top of the cutting platform. The mounting slots are divided into two groups located on both sides of the cutting slot. Each mounting slot has two first springs vertically and symmetrically arranged at its bottom. Each mounting slot has a floating clamping block vertically slidably connected inside. The top of the floating clamping block protrudes from the top of the cutting platform, and the bottom of each floating clamping block is connected to the top of the two first springs. Each floating clamping block is made of wear-resistant polyurethane material.

[0006] Furthermore, the cutting assembly includes a drive cylinder longitudinally positioned directly above the cutting groove. The bottom output end of the drive cylinder is equipped with a cutting device, which is located on one side of the cutting groove. The drive cylinder can drive the cutting device to move from one side of the cutting groove to the other side of the cutting groove to perform the cutting operation on the metal sheet.

[0007] Furthermore, the plate clamping and lateral movement device includes clamping block assemblies at the four corners of the top of the cutting platform, a driving clamping assembly at the bottom of the cutting platform, and a lateral movement assembly at the bottom of the driving clamping assembly; each clamping block assembly includes an L-shaped clamping sleeve located at the top corner of the cutting platform, and an L-shaped clamping block is vertically slidably connected to the top of the clamping sleeve via a second spring. The clamping sleeve and clamping block are flush with the clamping contact surface of the metal plate, and each of the four clamping block assemblies is symmetrically arranged with the adjacent clamping block assembly.

[0008] Furthermore, the drive clamping assembly includes a clamping box located on one side of the bottom of the cutting platform. The top of the clamping box has two sliding blocks that are laterally slidably connected to the clamping box, and the two sliding blocks are symmetrically arranged. A linkage rod is rotatably provided in the middle of the top of the clamping box. The two ends of the linkage rod are rotatably connected to one end of two connecting rods, and the other ends of the two connecting rods are rotatably connected to the middle of two adjacent sliding blocks.

[0009] Furthermore, a first electric push rod is laterally arranged on one side of the top of the clamping box. The output end of the first electric push rod is connected to the side end of one of the sliding blocks. Four sliding openings are symmetrically arranged on both sides of the clamping box. A connecting rod is provided on both sides of each sliding block. The side end of the connecting rod passes through the sliding opening on the side end of the clamping box, and the top of the connecting rod is connected to the side end of the clamping sleeve in the adjacent clamping block assembly. The sliding opening facilitates the lateral sliding of the connecting rod and the clamping sleeve.

[0010] Furthermore, the lateral movement component includes symmetrical slide rails arranged laterally on both sides of the bottom of the cutting platform. The clamping box slides laterally with the bottom of the cutting platform via the slide rails. A second electric push rod is arranged laterally in the center directly below the clamping box. The tail end of the second electric push rod is connected to one side of the bottom of the cutting platform, and the output end of the second electric push rod is connected to the bottom of the clamping box. By controlling the extension and retraction of the output end of the second electric push rod, the metal plate in the clamped state can be moved laterally to adjust the cutting position of the metal plate.

[0011] Furthermore, the top clamping adjustment device includes a drive clamping assembly located directly above the cutting platform. The drive clamping assembly includes third electric push rods symmetrically arranged on both sides of the top of the base plate. The third electric push rods are vertically arranged with their output ends facing upwards. A mounting plate is horizontally arranged directly above the cutting platform. The bottom sides of the mounting plate are respectively connected to the output ends of the two third electric push rods. A first clamping plate and a second clamping plate are spaced apart directly below the mounting plate.

[0012] Furthermore, the gap between the first and second clamping plates is located directly above the cutting groove, and the dimensions of the first and second clamping plates match the top dimensions of the cutting platform. The top clamping adjustment device also includes six rigid-flexible adjustment components. A rigid-flexible adjustment component is provided at each of the four corners of the top of the first clamping plate, and a rigid-flexible adjustment component is provided on each of the two sides of the top of the second clamping plate.

[0013] Furthermore, the rigid-flexible adjustment assembly includes a sliding cylinder vertically disposed at the bottom of the mounting plate. A clamping column is vertically slidably connected to the bottom of the sliding cylinder, and the clamping column is rotatably engaged with the sliding cylinder. The bottom of the clamping column in the rigid-flexible adjustment assembly corresponding to the first or second clamping plate is rotatably connected to the top of the first or second clamping plate. A stop rod is provided through the middle of the clamping column, and a third spring is sleeved on the outside of the clamping column. The top of the third spring is connected to the bottom of the sliding cylinder, and the bottom of the third spring contacts the top of the stop rod. A stop frame is provided on one side of the sliding cylinder. When the third spring is in a contracted state and the top of the sliding cylinder is flush with the top of the clamping column, and the clamping column is rotated to make the stop rod in a longitudinal state, the bottom of the stop rod abuts against the lower part of the stop frame, which can lock the position and state of the clamping column and the third spring. When the stop rod is disengaged from the stop frame and the clamping column is rotated to make the stop rod in a lateral state, the third spring is in an anti-loosening state.

[0014] The present invention has the following advantages: (1) Compared with the prior art, this device firstly relies on the floating clamping anti-deviation device arranged in the cutting platform array to achieve multi-point floating support for the bottom of the plate, eliminating the problem of the plate being suspended and warped in the middle of the cutting; secondly, the top clamping adjustment device can switch the clamping conditions through mechanical rotation, switching between rigid clamping and flexible clamping modes for metal plates of different thicknesses and hardnesses. Thick plates are rigidly clamped to prevent slippage, while thin plates are flexibly pressed to prevent damage to the plate surface, effectively improving the adaptability of the plate; after the plate is partially cut and separated, this device can simultaneously retain the double limiting constraint force of top clamping and bottom floating support on the remaining parent material, effectively offsetting the cutting stress, preventing the parent material from shifting laterally, and improving the continuous cutting dimensional accuracy and finished product yield. Meanwhile, this device has a clamping and lateral movement structure, which can simultaneously complete the centering and clamping of the sheet metal and the lateral adjustment of the cutting point, reducing the manual alignment process. It enables the clamping force on the top surface of the metal sheet to be adjusted according to the thickness of the sheet metal while cutting it, avoiding damage to the surface of the sheet metal. It can also effectively prevent the unprocessed sheet metal from shifting laterally during cutting, thus improving the yield of sheet metal cutting. Attached Figure Description

Furthermore, the drive clamping assembly 62 includes a clamping box 621 located on one side of the bottom of the cutting platform 2. The top of the clamping box 621 has two sliding blocks 622 that are laterally slidably connected to the clamping box 621, and the two sliding blocks 622 are symmetrically arranged. The top center of the clamping box 621 has a linkage rod 623 rotatably connected to one end of two connecting rods 624, and the other ends of the two connecting rods 624 are rotatably connected to the center of two adjacent sliding blocks 622.

The output end of the first electric push rod 625 is connected to the side end of one of the sliding blocks 622. Four sliding openings 626 are symmetrically arranged on both sides of the clamping box 621. A connecting rod 627 is provided on both sides of each sliding block 622. The side end of the connecting rod 627 passes through the sliding opening 626 on the side of the clamping box 621, and the top of the connecting rod 627 is connected to the side end of the clamping sleeve 611 in the adjacent clamping block assembly 61. The sliding opening 626 facilitates the lateral sliding of the connecting rod 627 and the clamping sleeve 611. Furthermore, the lateral movement component 63 includes symmetrical and laterally arranged slide rails 631 on both sides of the bottom of the cutting platform 2. The clamping box 621 is laterally slidably engaged with the bottom of the cutting platform 2 through the slide rails 631. A second electric push rod 632 is laterally arranged in the middle of the bottom of the clamping box 621. The tail end of the second electric push rod 632 is connected to one side of the bottom of the cutting platform 2. The output end of the second electric push rod 632 is connected to the bottom of the clamping box 621. By controlling the extension and retraction of the output end of the second electric push rod 632, the metal plate in the clamped state can be moved laterally to adjust the cutting position of the metal plate. Furthermore, the top clamping adjustment device 7 includes a drive clamping assembly 71 located directly above the cutting platform 2. The drive clamping assembly 71 includes third electric push rods 711 symmetrically arranged on both sides of the top of the base plate 1. The third electric push rods 711 are vertically arranged with their output ends facing upwards. A mounting plate 712 is horizontally arranged directly above the cutting platform 2. The bottom sides of the mounting plate 712 are respectively connected to the output ends of the two third electric push rods 711. A first clamping plate 713 and a second clamping plate 714 are spaced apart directly below the mounting plate 712. Furthermore, the gap between the first clamping plate 713 and the second clamping plate 714 is located directly above the cutting groove 3. The dimensions of the first clamping plate 713 and the second clamping plate 714 are matched with the top dimensions of the cutting platform 2. The top clamping adjustment device 7 also includes six rigid-flexible adjustment components 72. A rigid-flexible adjustment component 72 is provided at each of the four corners of the top of the first clamping plate 713, and a rigid-flexible adjustment component 72 is provided on each of the two sides of the top of the second clamping plate 714. Furthermore, the rigid-flexible adjustment component 72 includes a sliding cylinder 721 vertically disposed at the bottom of the mounting plate 712. A clamping column 722 is vertically slidably connected to the bottom of the sliding cylinder 721, and the clamping column 722 is rotatably engaged with the sliding cylinder 721. The bottom of the clamping column 722 in the rigid-flexible adjustment component 72 corresponding to the first clamping plate 713 or the second clamping plate 714 is rotatably connected to the top of the first clamping plate 713 or the top of the second clamping plate 714. A stop rod 723 is provided through the middle of the clamping column 722, and a third spring 724 is sleeved on the outside of the clamping column 722. The top of the third spring 724 is connected to the sliding cylinder 712. 21 is connected at the bottom and the bottom of the third spring 724 contacts the top of the stop rod 723. A stop frame 725 is provided on one side of the sliding cylinder 721. The third spring 724 is in a contracted state and the top of the sliding cylinder 721 is flush with the top of the pressing column 722. When the pressing column 722 is rotated to make the stop rod 723 in a longitudinal state, the bottom of the stop rod 723 abuts against the lower part of the stop frame 725, which can lock the position and state of the pressing column 722 and the third spring 724. When the stop rod 723 is disengaged from the stop frame 725 and the pressing column 722 is rotated to make the stop rod 723 in a transverse state, the third spring 724 is in an anti-loosening state.

[0019] like Figures 1 to 12 As shown, in this embodiment, after the metal sheet is loaded and positioned, it is placed against the top surface of the cutting platform 2, and the four corners of the sheet are located inside the four corner clamping block assembly 61 of the platform. In the initial state, the floating clamping block 43 is supported by the bottom first spring 42, and the top surface protrudes from the top surface of the cutting platform 2. It supports the bottom surface of the sheet at multiple points, realizing the flexible floating support of the sheet at multiple points, avoiding the problems of the middle of the sheet being suspended and rigid support. The top clamping adjustment device 7 presses down against the top surface of the sheet. As the top clamping force is gradually applied, the metal sheet is pressed down as a whole, and the bottom polyurethane floating clamping block 43 is squeezed simultaneously. The floating clamping block 43 is compressed by the force, and the first spring 42 symmetrically arranged at the bottom moves vertically downward along the mounting groove 41. The deformation height of the bottom surface of the sheet is adaptively adjusted to adjust the support height. The bottom surface of the sheet is kept uniformly floating and supported throughout the process, dispersing the local force of the sheet cutting and avoiding the warping deformation of the middle of the sheet. When corner clamping of metal sheets is required, the first electric push rod 625 pushes the single-sided sliding block 622 to slide laterally. Through the linkage rod 623 and two sets of connecting rods 624, the sliding blocks 622 on both sides slide symmetrically towards each other. Then, through the connecting rod 627, the four corner clamping sleeves 611 are synchronously pulled towards the center to adapt to different lengths and specifications of sheets and complete the corner centering clamping. When the cutting point needs to be adjusted, the second electric push rod 632 extends and retracts to drive the clamping box 621 to slide laterally along the slide rail 631, and the entire clamped sheet moves laterally in sync, accurately adjusting the cutting position of the sheet relative to the cutting component 5 without the need for manual secondary alignment and calibration. The top clamping adjustment device 7 drives the mounting plate 712 to rise and fall as a whole through the third electric push rods 711 arranged vertically on both sides, thereby adjusting the overall downward stroke of the first clamping plate 713 and the second clamping plate 714 to adapt to the downward pressure of the foundation of different thickness plates. The gap between the first clamping plate 713 and the second clamping plate 714 is aligned with the cutting groove 3 to avoid the cutting path of the cutting component 5. The top clamping force and the rigid-flexible clamping mode are independently controlled and switched by six sets of rigid-flexible adjustment components 72. Under normal conditions, the third spring 724 inside the component is in a contracted and locked state. Rotating the clamping column 722 drives the middle stop rod 723 to rotate to the longitudinal position. The stop rod 723 engages with the stop frame 725 to achieve limit locking. The clamping plate has no spring buffer stroke, forming a constant rigid clamping force on the top surface of the plate. It is suitable for cutting hard and thick plates such as carbon steel and stainless steel with a thickness of 3mm or more. It relies on rigid clamping to provide sufficient friction and prevent slippage during cutting. When processing soft and easily deformable plates such as aluminum alloy and copper with a thickness of 0.5mm-3mm, the clamping column 722 is rotated in the opposite direction, so that the stop rod 723 is disengaged from the stop frame 725 and rotates to the lateral position, releasing the locking effect of the components. The third spring 724 returns to the elastic buffer state. At this time, the downward pressing force of the clamping plate is provided by the elastic deformation of the third spring 724, which turns into flexible elastic clamping, reducing the unit pressure intensity on the top surface of the plate and avoiding appearance damage such as dents, scratches, and plastic deformation on the surface of the thin plate. During the process of the plate being pressed down, the four corner clamping block assembly 61 adapts to the change in plate height. The clamping block 612 inside the clamping block assembly 61 slides vertically relative to the clamping sleeve 611 with the second spring, and moves down synchronously with the plate. The inner end face of the clamping block 612 and the clamping sleeve 611 always keeps in contact with the side wall of the plate corner. The plate is laterally clamped and limited throughout the process, and there will be no problem of clamping separation or clamping tightness imbalance due to the plate sinking under pressure. After completing the top and bottom limiting, four-corner clamping, and pressing mode switching of the sheet metal, the cutting assembly 5 starts operation. The drive cylinder 51 drives the lower cutting device 52 to move longitudinally, moving along the cutting groove 3 to complete the through-cutting of the sheet metal. During the cutting process, the first pressing plate 713 and the second pressing plate 714 press the sheet metal in sections. The top surface of the sheet metal on both sides of the cutting position is always under pressure and limited. The bottom floating pressing block 43 bears pressure and supports the bottom surface of the sheet metal in sections. After the sheet metal is partially cut and separated to generate waste, the unprocessed parent material still maintains the double limitation of bottom floating support and top section pressing, which counteracts the lateral displacement trend caused by the cutting shear stress. To prevent the base material from shifting at the point limit level, after cutting, the top clamping adjustment device 7 is raised to release the force, the first spring 42 rebounds and drives the floating clamping block 43 to reset and push out, the clamping block assembly 61 clamping block 612 resets with the rebound height of the plate, and drives the clamping assembly 62 to loosen the edge of the plate, thus completing the finished product unloading. In summary, it is possible to adjust the clamping force on the top surface of the metal plate according to the thickness of the plate while cutting the metal plate, so as to avoid damage to the surface of the plate, and effectively prevent the unprocessed plate from shifting laterally during cutting, thereby improving the yield of plate cutting.
