[0017] The beneficial effects of the present invention are as follows:

[0018] (1) The present invention realizes the rotation of a set of folding shaft bodies through the drive of a stepping motor and a reduction gear set, as well as the transmission of a transmission wheel and a transmission belt, that is, one end of a set of positioning seats undergoes a folding bend, while the other set of folding shaft bodies is meshed with it through a gear sleeve, thereby synchronously driving the other set of folding shaft bodies to flip towards each other, further realizing the synchronous folding of the two sets of positioning seats. During folding, the bottom crank seats b of the two sets of positioning seats are movably connected to the crank seat a through connecting rods, and drive the guide sliders to slide on the guide rails during folding to guide the folding of the two sets of positioning seats. Cooperating with the fixation of the sheet material by the electromagnetic structure in the positioning mechanism, the bending of the cutting part of the sheet material is realized. During the bending process, the hydraulic cylinder is started, and the power is output to the output plate through the hydraulic rod. The output plate passes through the gap between the two sets of folding shaft bodies and contacts the bottom end of the cutting part of the sheet material to further improve the bending efficiency of the sheet material, continuously expand the cutting opening and open the cutting opening, facilitating the next cutting and realizing the efficient cutting of relatively thick sheet materials.

[0019] (2) The present invention docks a conduit with a pump and a tank body, and drips an antireflection agent into the bent cutting groove to improve the next cutting effect. After repeatedly cutting with the bending structure for multiple times, the cutting of relatively thick sheet materials is completed, greatly improving the overall cutting effect and efficiency of the device.

[0020] (3) The present invention triggers the energization of the electromagnetic wire in the electromagnetic seat at the bottom of the magnetic plate on the positioning seat through the travel switch on the cutting platform. After the electromagnetic seat is energized, it endows the magnetic plate with magnetic force to adsorb and fix the sheet material fed to the designated position to complete positioning. By driving the threaded rod, the threaded connection of the threaded seat will drive the clamping plate at the bottom end of the pressure plate to move downward to clamp and press the two side edges of the cutting part of the sheet material, so as to provide a stable fixing effect for the bending of the sheet material while realizing automatic positioning. At the same time, the clamping structure can avoid the deformation of the cutting edge of the sheet material during the bending process.

[0021] (4) The present invention drives the rotation of the gears in the longitudinal drive group and the transverse drive group through motors. Each gear meshes with the longitudinal rack and the transverse rack, thereby realizing the horizontal and vertical movement of the displacement crossbeam and the cutting equipment, so as to realize the horizontal and vertical position adjustment of the laser head and the movement during cutting. By driving the screw rod to rotate on the bearing of the vertical plate through the vertical motor, the nut on the adjustment plate is threadedly connected to the screw rod, and the vertical height adjustment of the laser head is realized through the guidance of the slider and the guide rail, thereby ensuring the accuracy of cutting.

[0022] (5) The present invention realizes the movement of the conveyor belt through the drive of the transport wheel a on the transport shaft a by the transport motor, the transmission of the transport wheel b on the transport shaft b, and the tensioning of the tensioning wheel on the tensioning shaft. The sheet material at the lowest end of the storage frame is transported to the cutting platform through the conveyor belt to complete the loading, reducing the manual loading process and improving the processing efficiency.

[0023] In summary, the present invention has the advantages of high efficiency and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

The nut 535 on the adjusting plate 532 is threadedly connected to the lead screw 534, and the vertical height adjustment of the laser head 543 is realized through the guidance of the slider and the guide rail. The laser device is started to cut the plate 212;

[0069] Step Four: Multiple Bending and Cutting Process: After the laser head 543 reciprocally cuts the cutting area once, through the drive of the stepper motor 414 and the reduction gear set 416, and the transmission of the transmission wheel 418 and the transmission belt 419, a set of folding shaft bodies 411 gradually rotate, that is, one end of a set of positioning seats 401 flips, causing half of the sheet 212 separated by the cut to bend. The other set of folding shaft bodies 411 is meshed through the gear sleeve 412, thereby synchronously driving the other set of folding shaft bodies 411 to flip towards each other, further realizing the synchronous folding of the two sets of positioning seats 401. During folding, the bottom crank seats b425 of the two sets of positioning seats 401 are movably connected to the crank seats a424 through the connecting rods 426, and drive the guiding sliders 423 to slide on the guiding rails 422 during folding to guide the folding of the two sets of positioning seats 401. Cooperating with the fixation of the sheet 212 by the electromagnetic structure in the positioning mechanism 4, it realizes a gradually smaller degree of bending at the cutting area of the sheet 212, making the cut continuously expand and open the cutting opening. Bending once and cutting once in cooperation is convenient for the contact of the laser head 543 to improve the cutting effect. During the bending process, the hydraulic cylinder 432 is started, and the power is gradually output to the output plate 434 through the hydraulic rod 433. The output plate 434 passes through the gap between the two sets of folding shaft bodies 411 and contacts the bottom end of the cutting area of the sheet 212, cooperating with the above-mentioned bending setting to further improve the bending efficiency of the thicker sheet 212 during cutting, so as to improve the cutting efficiency;

[0070] Step Five: Anti-Reflection Drop Coating Process: The anti-reflection agent is dropped into the bent cutting groove through the connection of the conduit 547 with the pump and the tank body, improving the next cutting effect. After repeatedly cutting in cooperation with the bending structure for multiple times, the cutting of the thicker sheet 212 is completed.

[0071] It should be noted that: In this embodiment, the thicker steel plate is cut multiple times. The first cut makes a cut in the steel plate, and then the two sides of the steel plate are bent (the angle should not be too large, and the preferred bending angle is 5°). The cut after bending is V-shaped. The anti-reflection agent is dropped into the V-shaped cut. The laser head 543 makes the second cut at the V-shaped cut. The anti-reflection agent enhances the plasma laser cutting effect; then the two sides of the steel plate are bent again, gradually increasing the angle of the V-shaped cut and then gradually cutting. The increase in the angle of the V-shaped cut facilitates the anti-reflection agent to flow to the bottom of the cut, and at the same time is also conducive to the laser head 543 inserting into the V-shaped cut for another cut. Repeat multiple times until the stainless steel plate is cut off.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
