[0028] Example

[0029] Reference Figure 1-Figure 4 The present embodiment provides a sheet iron cutting machine, including a workbench 110, on which a cutting mechanism 120 is provided, and on which a telescopic adjustment mechanism 130 is also provided. Two flexible support plates 140 are hingedly connected to the top of the telescopic adjustment mechanism 130, and a gap is provided between the two flexible support plates 140, and the gap is located below the cutting station of the cutting mechanism 120. The flexible support plate 140 is used to place an arc-shaped sheet iron 150, and the flexible support plate 140 includes a plurality of arc-shaped plates 141 hinged to each other. The telescopic adjustment mechanism 130 is used to drive the corresponding arc-shaped plates 141 to rotate so as to adjust the overall curvature of the flexible support plate 140.

[0030] In this embodiment, a flexible support plate 140 is provided to place the arc-shaped iron sheet 150. According to the curvature of the arc-shaped iron sheet 150, the telescopic adjustment mechanism 130 can be used to drive a plurality of corresponding arc-shaped plates 141 in the flexible support plate 140 to rotate, thereby adjusting the overall curvature of the flexible support plate 140, and realizing the flexible stretching effect of the flexible support plate 140, that is, the flexible support plate 140 can adapt to the arc-shaped iron sheet 150 of the corresponding curvature, ensuring the fit with the arc-shaped iron sheet 150, thereby ensuring the clamping reliability, thereby improving versatility, and eliminating the need for frequent replacement operations, thereby improving work efficiency.

[0031] Working principle: When cutting is required, the arc-shaped iron sheet 150 is placed on the top surfaces of the two flexible support plates 140, and the curvature of the flexible support plates 140 is adjusted to fit the lower surfaces of the arc-shaped iron sheet 150, so that the arc-shaped iron sheet 150 to be cut is placed in the gap between the two flexible support plates 140, and the arc-shaped iron sheet 150 is cut by the cutting mechanism 120, and the gap cooperates with the cutting station so that the cutting mechanism 120 does not touch the flexible support plate 140.

[0032] As an optional implementation, the telescopic adjustment mechanism 130 includes a bottom plate 131 , on which a plurality of first telescopic cylinders 132 are hinged, and the first telescopic cylinders 132 are hinged to the bottoms of corresponding arc plates 141 .

[0033] In this embodiment, when adjustment is required, the first telescopic cylinder 132 is used to drive the corresponding arc plates 141 to rotate the corresponding angles, so that all the arc plates 141 fit the lower surface of the arc-shaped iron sheet 150 as closely as possible, thereby realizing automatic adjustment of the curvature of the flexible support plate 140 and ensuring the adjustment accuracy.

[0034] As an optional embodiment, the number of arc plates 141 on the same flexible support plate 140 is an odd number, the bottom of the middle arc plate 141 is connected to a pillar 160, the pillar 160 is connected to the bottom plate 131, and multiple first telescopic cylinders 132 are evenly distributed on both sides of the pillar 160.

[0035] In this embodiment, the middle arc plate 141 does not need to be rotated, so the middle of the arc iron sheet 150 is placed on the top surface of the middle arc plate 141 for easy positioning and installation, and then the rotation angles of the remaining arc plates 141 are adjusted to fit the arc iron sheet 150.

[0036] As an optional embodiment, the cutting mechanism 120 includes a frame 121 arranged on the workbench 110, a moving block 122 is slidably arranged at the top of the frame 121, a laser cutting head 123 is arranged at the bottom of the moving block 122, and the laser cutting head 123 is located directly above the gap opening.

[0037] In this embodiment, the laser cutting head 123 can be used to perform laser cutting on the arc-shaped iron sheet 150 with high cutting accuracy, and the moving block 122 can drive the laser cutting head 123 to move in a straight line, thereby cutting along the cutting line of the arc-shaped iron sheet 150. It should be noted that the moving block 122 can be automatically moved by a screw drive assembly, and can also be configured with X and Y axis movement functions to meet more cutting requirements.

[0038] As an optional embodiment, at least two second telescopic cylinders 170 are provided on the workbench 110, the base plate 131 is connected to the top of the second telescopic cylinder 170, and a clamping mechanism 180 is provided at the top of the frame 121, and the clamping mechanism 180 is used to clamp the upper surface of the arc-shaped iron sheet 150.

[0039] In this embodiment, after the arc-shaped iron sheet 150 is installed on the flexible support plate 140, the bottom plate 131 is driven upward by the second telescopic cylinder 170, and the arc-shaped iron sheet 150 moves upward accordingly until the upper surface of the arc-shaped iron sheet 150 is in contact with the clamping mechanism 180, thereby achieving a clamping and clamping effect on the upper and lower surfaces of the arc-shaped iron sheet 150 to ensure that the arc-shaped iron sheet 150 will not deviate during the cutting process.

[0040] As an optional embodiment, the clamping mechanism 180 includes a hollow cylinder 181 connected to the top of the frame 121, and a telescopic rod 182 is movably arranged in the hollow cylinder 181. The telescopic rod 182 extends out of the bottom of the hollow cylinder 181 and is hinged with an arc-shaped pressure block 183. The arc-shaped pressure block 183 is used to press the upper surface of the arc-shaped iron sheet 150. A stopper 184 is fixedly sleeved on the telescopic rod 182, and a compression spring 185 is sleeved on the telescopic rod 182 and located between the stopper 184 and the bottom of the hollow cylinder 181.

[0041] In this embodiment, when the arc-shaped iron sheet 150 moves up to contact the arc-shaped pressing block 183, the arc-shaped iron sheet 150 continues to move up for a distance. At this time, the telescopic rod 182 is retracted into the hollow tube 181. Under the action of the compression spring 185, the telescopic rod 182 has a force to extend out of the hollow tube 181, so that the arc-shaped pressing block 183 is firmly pressed against the upper surface of the arc-shaped iron sheet 150 to ensure the clamping reliability.

[0042] It should be noted that a limit block can be set when the telescopic rod 182 extends into the hollow tube 181, and a limit step is correspondingly set in the hollow tube 181. Under the limiting action of the limit block and the limit step, the telescopic rod 182 will not separate from the hollow tube 181.

[0043] As an optional embodiment, the arc pressure block 183 is made of rubber material, so that the arc pressure block 183 has a certain stretching effect, so that it can adapt to the fit of the arc-shaped iron sheet 150 with different curvatures, further improving the clamping reliability. At the same time, the arc pressure block 183 has a certain extrusion deformation effect, which can avoid rigid contact from causing indentations on the surface of the arc-shaped iron sheet 150, thereby ensuring the surface quality of the arc-shaped iron sheet 150.

[0044] As an optional implementation, a pressure sensor 186 in contact with the compression spring 185 is provided at the bottom of the hollow cylinder 181 . The pressure sensor 186 is electrically connected to a controller 190 , and the controller 190 is electrically connected to the second telescopic cylinder 170 .

[0045] In this embodiment, when the arc-shaped pressure block 183 is pressed against the arc-shaped iron sheet 150, the telescopic rod 182 is retracted into the hollow tube 181. At this time, the compression spring 185 generates pressure on the pressure sensor 186. The pressure sensor 186 can detect the pressure size. When the preset pressure is reached, the pressure data can be transmitted to the controller 190. The controller 190 processes the pressure data and converts it into an electrical signal to control the second telescopic cylinder 170 to stop the action, thereby accurately controlling the clamping force on the arc-shaped iron sheet 150 and reducing human operation errors.

[0046] It should be noted that the controller 190 here can adopt a PLC controller of model S7-200 to meet the use requirements.

[0047] As an optional implementation, the bottom plate 131 is in an inverted V shape, at least two vibrators 210 are disposed at the bottom of the bottom plate 131 , and slag leakage grooves 111 are respectively opened at two ends of the workbench 110 corresponding to the bottom plate 131 .

[0048] In this embodiment, the debris generated by cutting can automatically slide down along both sides of the upper surface of the inverted V-shaped bottom plate 131, and the vibrator 210 can vibrate the bottom plate 131 to promote the debris to slide down, and then leak out from the slag trough 111 on the workbench 110, so as to facilitate the subsequent centralized collection of the debris. For example, a slag discharge pipe or a receiving box is arranged under the slag trough 111 to avoid excessive accumulation of debris and reduce frequent cleaning work.

[0049] As an optional implementation, a slag collecting box 220 is provided under the slag leakage chute 111 , T-shaped blocks 230 are connected to both sides of the top of the slag collecting box 220 , and a T-shaped slot matching the corresponding T-shaped block 230 is opened at the bottom of the workbench 110 .

[0050] In this embodiment, the cutting debris can be directly accumulated in the slag collecting box 220 through the slag leakage groove 111. Here, the slag collecting box 220 is slidably connected by the T-shaped block 230 and the T-shaped groove. When there is a lot of accumulation, the slag collecting box 220 can be directly pulled out from the bottom of the workbench 110, cleaned and then installed again. The operation is convenient and quick.

[0051] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
