In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] As shown in Figures 1 to 4 The utility model discloses a kind of anti-warp cutting devices for cold-rolled sheet processing, including base 1, base 1 is equipped with the electromagnetic chuck 2 for adsorbing plate, after placing the plate to be cut on electromagnetic chuck 2, by the adsorption of plate to electromagnetic chuck 2, plate can be attached with electromagnetic chuck 2, to ensure the flatness of plate when cutting, so it can prevent plate from warping when cutting, the electromagnetic chuck 2 uses electromagnetic principle, by making inside coil energized can generate magnetic force on the surface of electromagnetic chuck 2, and cold-rolled sheet is generally steel plate, so that cold-rolled sheet can be adsorbed, it is same with the electromagnetic chuck 2 used in CNC, so do not make too much repetition;

[0022] Subsequently, laser cutting device 3 above electromagnetic chuck 2 can be moved left and right and forward and backward by first drive mechanism 4 and second drive mechanism 5 respectively to complete cutting of plate, and the specific structure of first drive mechanism 4 and second drive mechanism 5 is same with the drive mechanism structure disclosed in the patent document with publication number CN220659432U, that is, ball screw sliding table is used to drive laser cutting device 3 to move, so do not make too much repetition.

[0023] In the embodiment, base 6 is fixed on the outer periphery of laser cutting device 3, for example, in the form of welding, detachable connecting seat 7 is connected to base 6, and first rolling wheel 8 and second rolling wheel 9 described below are connected to base 6 through connecting seat 7, by detachably arranging connecting seat 7, overall assembly can be facilitated, specifically, connecting seat 7 is provided with guide assembly, the guide assembly includes two symmetrically arranged guide pipes 101, guide pipe 101 is fixed to connecting seat 7, and connecting rod 102 is sleeved in guide pipe 101, by fixing mounting seat 103 on one end of connecting rod 102 away from guide pipe 101, two ends of first rolling wheel 8 or second rolling wheel 9 can be connected to connecting flange 103a on both sides of mounting seat 103, so that the connection between first rolling wheel 8 or second rolling wheel 9 and connecting seat 7 can be realized;

[0024] Furthermore, the connecting rod 102 is sleeved in the guide pipe 101, so that the connecting rod 102 can be telescoped by sliding in the guide pipe 101, and the outer periphery of the guide pipe 101 is sleeved with the pressing spring 104, one end of which is fixed to the connecting seat 7 and the other end is fixed to the mounting seat 103. Since the rolling direction of the first rolling wheel 8 is consistent with the moving direction of the first driving mechanism 4, and the rolling direction of the second rolling wheel 9 is consistent with the moving direction of the second driving mechanism 5, when the laser cutter 3 is moved by the first driving mechanism 4 to cut the plate, the clutch mechanism can drive the first rolling wheel 8 to approach the plate and the second rolling wheel 9 to move away from the plate. When the first rolling wheel 8 contacts the plate, the first rolling wheel 8 can be extruded, so that the connecting rod 102 slides towards the guide pipe 101 to compress the pressing spring 104. The force generated by the deformation of the pressing spring 104 can act on the plate through the first rolling wheel 8. Thus, with the movement of the laser cutter 3, the first rolling wheel 8 can roll along the moving direction of the laser cutter 3 to press the plate and apply stress, while preventing the plate from being warped due to the sliding friction between the second rolling wheel 9 and the plate.

[0025] Similarly, when the laser cutter 3 is moved by the second driving mechanism 5 to cut the plate, the clutch mechanism described below can drive the second rolling wheel 9 to approach the plate and the first rolling wheel 8 to move away from the plate. When the second rolling wheel 9 contacts the plate, the second rolling wheel 9 can be extruded, so that the corresponding connecting rod 102 slides towards the guide pipe 101 to compress the pressing spring 104. The force generated by the deformation of the pressing spring 104 can act on the plate through the second rolling wheel 9. Thus, with the movement of the laser cutter 3, the second rolling wheel 9 can roll along the moving direction of the laser cutter 3 to press the plate and apply stress, while preventing the plate from being warped due to the sliding friction between the first rolling wheel 8 and the plate, thereby ensuring that the rolling direction of the rolling wheel is adapted to the moving direction of the laser cutter 3, and avoiding the friction force causing the plate to warp during cutting.

[0026] The specific structure of the clutch mechanism in this embodiment includes an electromagnet 111 fixed to the connecting seat 7 and located between the two guide pipes 101. The mounting seat 103 is fixed with a magnetic block 112 on the side facing the electromagnet 111. Through the setting of the electromagnet 111, a magnetic field can be generated after energization to attract the magnetic block 112, so that the mounting seat 103 can approach the connecting seat 7. In this way, when the first drive mechanism 4 drives the laser cutter 3 to move, the corresponding electromagnet 111 of the second rolling wheel 9 is energized, and the corresponding electromagnet 111 of the first rolling wheel 8 is de-energized, so that the second rolling wheel 9 moves away from the plate, while the first rolling wheel 8 can contact the plate. Similarly, when the second drive mechanism 5 drives the laser cutter 3 to move, the corresponding electromagnet 111 of the first rolling wheel 8 is energized, and the corresponding electromagnet 111 of the second rolling wheel 9 is de-energized, so that the first rolling wheel 8 moves away from the plate, while the second rolling wheel 9 can contact the plate. Thus, the rolling direction of the rolling wheel can be adapted to the moving direction of the laser cutter 3. It should be noted that, since the laser cutter 3 needs to frequently switch between left and right moving directions and front and back moving directions during actual cutting, the mounting seat 103 driven by the electromagnet 111 can have faster response efficiency to meet the requirement of frequent switching of moving direction.

[0027] In this embodiment, the detachable structure of the connecting seat 7 and the base 6 is that the base 6 is provided with a downwardly recessed annular adjusting groove 61, and the bottom of the connecting seat 7 is provided with an annular guide block 71 extending towards the annular adjusting groove 61. The annular guide block 71 is coupled to the annular adjusting groove 61 and can form a sliding fit therebetween. When the connecting seat 7 is connected to the base 6, the annular guide block 71 and the annular adjusting groove 61 can quickly position the installation of the connecting seat 7. That is, after the annular guide block 71 is inserted into the annular adjusting groove 61, the installation position of the connecting seat 7 can be determined.

[0028] In addition, the annular guide block 71 is further provided with an inwardly recessed positioning groove 711, and the annular adjusting groove 61 is provided with a positioning block 611 opposite to the positioning groove 711. The positioning block 611 and the positioning groove 711 can form a sliding fit therebetween. In this way, when the annular guide block 71 is inserted into the annular adjusting groove 61, the positioning block 611 is first ensured to be opposite to the positioning groove 711, and then the annular guide block 71 is inserted into the annular adjusting groove 61. In this way, the rolling directions of the first rolling wheel 8 and the second rolling wheel 9 can be respectively consistent with the moving directions of the first drive mechanism 4 and the second drive mechanism 5, so as to improve the debugging efficiency and accuracy of the setting directions of the first rolling wheel 8 and the second rolling wheel 9.

[0029] In addition, a first threaded hole 62 is arranged in the annular adjusting groove 61, the first threaded hole 62 is multiple and is uniformly distributed in a circle, and a second threaded hole 72 is arranged in the connecting seat 7 and penetrates through, the second threaded hole 72 is opposite to the first threaded hole 62, so that the detachable connection between the connecting seat 7 and the base 6 can be realized by rotating the locking piece matched with the first threaded hole 62 and the second threaded hole 72 into or out of the threaded hole.
