DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0028] Example 2

[0029] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] The horizontal moving assembly includes a first motor 9 and a screw rod 10. The screw rod 10 is installed on the inner side of the mounting frame 2. The first motor 9 is installed at one end of the mounting frame 2 and is connected to the screw rod 10 through the output end. A moving seat 11 is provided on the outer sleeve of the upper end of the plate lifting cylinder 3. One side of the moving seat 11 is connected to the screw rod 10 through a slider. The setting of the horizontal moving assembly allows personnel to drive the screw rod 10 to rotate through the first motor 9, and the screw rod 10 drives the moving seat 11 to move left and right when it rotates, and then the moving seat 11 drives the plate lifting cylinder 3 to move synchronously, thereby achieving the plate feeding effect; a number of guide rods are provided on both sides of the moving seat 11 for sliding. 12. Both ends of the guide rod 12 are fixed on the inner wall of the mounting frame 2. The setting of the guide rod 12 makes the moving seat 11 more stable when moving. The circular rotating component includes a mounting plate 14 and a second motor 15. The electromagnetic suction cup 4 is installed on the lower surface of the mounting plate 14. The second motor 15 is set at the output end of the plate lifting cylinder 3. The output end of the second motor 15 is connected to the mounting plate 14. The setting of the circular rotating component can drive the electromagnetic suction cup 4 to rotate, that is, drive the plate to rotate a certain angle, thereby allowing the plate to be cut into steel plates of different shapes according to specific needs during cutting, that is, the versatility of the cutting device is improved.

[0031] A mounting tube 13 is fixed to the output end of the plate lifting electric cylinder 3, and the second motor 15 is installed inside the mounting tube 13. A cylindrical protrusion is provided on the upper surface of the mounting plate 14, and the cylindrical protrusion is rotatably connected to the mounting tube 13 through a bearing. The setting of the mounting tube 13 is convenient for protecting the second motor 15 and sharing the burden of the second motor 15, that is, the second motor 15 is only responsible for driving the electromagnetic suction cup 4 to rotate, thereby reducing the failure rate of the second motor 15; an anti-slip groove is provided on the lower surface of the pressing plate 7, and an anti-slip pattern is provided on the upper surface of the workbench 1. The setting of the anti-slip pattern and the anti-slip groove makes the device more firmly fixed to the steel plate when in use, so that the steel plate is less likely to be accidentally displaced when being cut; the first motor 9 and the second motor 15 are both servo motors, and the width of the pressing plate 7 is greater than 15CM. The setting of the servo motor is convenient for accurately controlling the movement of the plate.

[0032] Principle and advantages of use: During the use of the utility model, when it is necessary to cut the steel plate, if the steel plate does not have magnetic attraction, the steel plate is directly placed on the upper surface of the workbench 1, and the steel plate is rotated and moved by manpower. When the position of the steel plate is determined, the pressing plate 7 can be pushed by the pressing plate lifting electric cylinder 5 to clamp and fix the steel plate, and then the cutter 8 is pushed by the cutter lifting electric cylinder 6 to contact the steel plate until the steel plate is cut off from the pressing plate 7 by the cutter 8, and the cutting of the steel plate is completed.

[0033] Furthermore, in the above process, if the cut steel plate has magnetic attraction, the electromagnetic suction cup 4 can be energized, that is, the steel plate is adsorbed on the lower surface of the electromagnetic suction cup 4. At this time, the steel plate can be fed by the first motor 9, and the second motor 15 can drive the electromagnetic suction cup 4 to rotate, that is, drive the steel plate to rotate synchronously. At this time, when the position and angle of the steel plate are determined, the plate lifting cylinder 3 pushes the electromagnetic suction cup 4 to move downward until the steel plate is clamped on the upper surface of the workbench 1, and the pressing plate 7 is further driven by the pressing plate lifting cylinder 5 to lift the steel plate. After being firmly clamped, the steel plate can then be cut by the cutter 8; in summary, through the mutual cooperation between the above-mentioned components, the present solution can firmly clamp the steel plate through the pressure plate lifting cylinder 5 and the electromagnetic suction cup 4 when in use, thereby avoiding the deformation and movement of the steel plate during the cutting process, which leads to incorrect size of the cut plate, and through the cooperation of the horizontal moving component and the circular rotating component, when processing the magnetic steel plate, the manpower of the personnel can be liberated, thereby improving the processing efficiency.

[0034] It should be further explained that the setting of the horizontal moving component allows personnel to drive the screw rod 10 to rotate through the first motor 9, and when the screw rod 10 rotates, it drives the moving seat 11 to move left and right, and then the moving seat 11 drives the plate lifting cylinder 3 to move synchronously, thereby achieving the plate feeding effect. The setting of the guide rod 12 makes the moving seat 11 more stable when moving. The setting of the circular rotating component can drive the electromagnetic suction cup 4 to rotate, that is, drive the plate to rotate a certain angle, thereby making it possible to cut steel plates of different shapes according to specific needs during cutting, thereby improving the versatility of the cutting device; the setting of the anti-slip grooves makes the device more firmly fixed to the steel plate when in use, so that the steel plate is less likely to be accidentally displaced when being cut.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
