[0025] A laser cutting machine capable of preventing a workpiece from warping comprises a cutting table 1 and a cutter 2 arranged above the cutting table 1, wherein a slideway 3 is provided on the bottom surface of the cutting table 1, a slider 4 is slidably arranged on the slideway 3, a movable plate 5 is fixedly installed on the bottom surface of the slider 4, a support rod 6 is fixedly installed on one side of the movable plate 5, an electromagnet 7 is commonly arranged at the end of the support rod 6, and the electromagnet 7 is arranged in a U shape, the slideway 3, the slider 4, the movable plate 5, the support rod 6 and the electromagnet 7 on the bottom surface of the cutting table 1 are all arranged in two symmetrical groups, and the slider 4 is provided with a support rod 6 on the end of the support rod 6. The cutting table 1 is provided with a limiter 8 for keeping the electromagnet 7 stable. The cutting table 1 is provided with an adjustment mechanism 9 for driving the cutter 2 to move horizontally and vertically, as well as to lift and lower vertically. The adjustment mechanism 9 includes a horizontal drive assembly 91 and a lifting drive assembly 92 arranged above the cutting table 1, and a vertical drive assembly 93 arranged on the cutting table 1. The horizontal drive assembly 91 includes a horizontal plate 911 arranged above the cutting table 1, a motor 912 fixedly mounted on the horizontal plate 911, a screw rod 913 rotatably arranged on the horizontal plate 911, and a sliding device The mounting seat 914 is mounted on the horizontal plate 911, the end of the output shaft of the motor 912 is fixedly mounted to one end of the screw rod 913, the mounting seat 914 is threadedly connected to the screw rod 913, the cutter 2 is fixedly mounted to the mounting seat 914, the lifting drive assembly 92 includes a mounting block 921 symmetrically arranged above the cutting table 1, and an electric telescopic column 922 fixedly mounted on the mounting block 921, the ends of the output shaft of the electric telescopic column 922 are respectively fixedly mounted to the bottom surface of the horizontal plate 911, and the vertical drive assembly 93 includes a mounting block 921 symmetrically arranged above the cutting table 1, and a mounting block 921 symmetrically arranged above the cutting table 1. A symmetrical slideway 931, and an electric push rod 932 fixedly installed in the slideway 931, the mounting block 921 is slidably set on the slideway 931, the end of the output shaft of the electric push rod 932 is fixedly installed on the side of the mounting block 921, the limiting member 8 includes a mounting opening 81 opened on the side of the slider 4, a spring 82 set in the mounting opening 81, and a limiting block 83 slidably set on the mounting opening 81, the spring 82 is pressed between the slider 4 and the limiting block 83, and the limiting block 83 is in contact with the cutting table 1 at one end away from the spring 82.

[0026] When the steel plate is placed on the cutting table 1, in order to ensure that the steel plate does not tilt or shift during the cutting process, a slideway 3 is arranged below the cutting table 1. The slider 4 on the slideway 3 can slide to adjust the position. A movable plate 5 is fixed below the slider 4. The movable plate 5 is connected to the U-shaped electromagnet 7 through a support rod 6. When the electromagnet 7 is energized to generate a magnetic field, it will firmly adsorb the steel plate, thereby preventing the steel plate from moving or tilting during the cutting process. In order to further enhance the stability, a limiting member 8 is also arranged on the slider 4, including a spring 82 and a limiting block 83 in the mounting opening 81. The spring 82 presses the limiting block 83 toward the cutting table 1, so that the position of the slider 4 on the slideway 3 is more stable and will not be easily moved due to external force, thereby improving the stability of the electromagnet 7. In this way, the steel plate can be more stably fixed on the cutting table 1, and the distance between the electromagnets 7 can be adjusted in advance according to the size of the steel plate.

[0027] The transverse drive assembly 91 mainly realizes the transverse movement of the cutter 2 through the cooperation of the motor 912, the screw rod 913 and the mounting seat 914. The motor 912 is fixed on the transverse plate 911, and its output shaft is connected to one end of the screw rod 913. When the motor 912 is started, it drives the screw rod 913 to rotate. Since the mounting seat 914 and the screw rod 913 are threadedly connected, the rotation of the screw rod 913 drives the mounting seat 914 to move transversely along the transverse plate 911. In this way, the cutter 2 fixed on the mounting seat 914 can also be accurately positioned and adjusted transversely to meet different cutting requirements.

[0028] The lifting drive assembly 92 uses an electric telescopic column 922 to realize the lifting function of the cutter 2. The electric telescopic column 922 is fixed on the mounting block 921, and its output shaft is connected to the bottom surface of the horizontal plate 911. By controlling the telescopic length of the electric telescopic column 922, the height of the horizontal plate 911 (and the cutter 2 fixed thereon) can be flexibly adjusted, so that the cutter 2 can be quickly and accurately adjusted to a suitable working height according to the thickness and cutting requirements of different workpieces;

[0029] The vertical drive assembly 93 realizes the horizontal movement of the cutter 2 in the vertical plane through the cooperation of the electric push rod 932 and the mounting block 921. The electric push rod 932 is installed in the second slideway 931 opened on the cutting table 1, and its output shaft is connected to the side of the mounting block 921. When the electric push rod 932 is extended or retracted, it will push the mounting block 921 to move vertically and horizontally along the second slideway 931. Since the lifting drive assembly 92 and the horizontal drive assembly 91 are fixed on the mounting block 921, the entire cutter 2 system will also move accordingly, thereby realizing accurate cutting of different positions of the workpiece;

[0030] This laser cutting machine can effectively prevent the steel plate from warping and shifting during the cutting process, ensuring the accuracy and efficiency of cutting and is highly practical.

[0031] Two groups of support rods 6 are fixedly mounted on each group of the movable plates 5, and the electromagnets 7 are clamped and arranged at the ends of the support rods 6;

[0032] The electromagnet 7 is clamped on the end of the support rod 6, which not only makes the installation of the electromagnet 7 more stable, but also ensures that it will not shift due to vibration or other external forces during use, and also facilitates the replacement of electromagnets 7 of different sizes.

[0033] The top and bottom surfaces of the cutting table 1 are both provided with scales;

[0034] The top and bottom surfaces of the cutting table 1 are provided with scales, which provide precise references for operators and ensure the accuracy and efficiency of steel plate cutting.

[0035] Working principle:

[0036] When the steel plate is placed on the cutting table 1, in order to ensure that the steel plate does not tilt or shift during the cutting process, a slideway 3 is arranged below the cutting table 1. The slider 4 on the slideway 3 can slide to adjust the position. A movable plate 5 is fixed below the slider 4. The movable plate 5 is connected to the U-shaped electromagnet 7 through a support rod 6. When the electromagnet 7 is energized to generate a magnetic field, it will firmly adsorb the steel plate, thereby preventing the steel plate from moving or tilting during the cutting process. In order to further enhance the stability, a limiting member 8 is also arranged on the slider 4, including a spring 82 and a limiting block 83 in the mounting opening 81. The spring 82 presses the limiting block 83 toward the cutting table 1, so that the position of the slider 4 on the slideway 3 is more stable and will not be easily moved due to external force, thereby improving the stability of the electromagnet 7. In this way, the steel plate can be more stably fixed on the cutting table 1, and the distance between the electromagnets 7 can be adjusted in advance according to the size of the steel plate.

[0037] The transverse drive assembly 91 mainly realizes the transverse movement of the cutter 2 through the cooperation of the motor 912, the screw rod 913 and the mounting seat 914. The motor 912 is fixed on the transverse plate 911, and its output shaft is connected to one end of the screw rod 913. When the motor 912 is started, it drives the screw rod 913 to rotate. Since the mounting seat 914 and the screw rod 913 are threadedly connected, the rotation of the screw rod 913 drives the mounting seat 914 to move transversely along the transverse plate 911. In this way, the cutter 2 fixed on the mounting seat 914 can also be accurately positioned and adjusted transversely to meet different cutting requirements.

[0038] The lifting drive assembly 92 uses an electric telescopic column 922 to realize the lifting function of the cutter 2. The electric telescopic column 922 is fixed on the mounting block 921, and its output shaft is connected to the bottom surface of the horizontal plate 911. By controlling the telescopic length of the electric telescopic column 922, the height of the horizontal plate 911 (and the cutter 2 fixed thereon) can be flexibly adjusted, so that the cutter 2 can be quickly and accurately adjusted to a suitable working height according to the thickness and cutting requirements of different workpieces;

[0039] The vertical drive assembly 93 realizes the horizontal movement of the cutter 2 in the vertical plane through the cooperation of the electric push rod 932 and the mounting block 921. The electric push rod 932 is installed in the second slideway 931 opened on the cutting table 1, and its output shaft is connected to the side of the mounting block 921. When the electric push rod 932 is extended or retracted, it will push the mounting block 921 to move vertically and horizontally along the second slideway 931. Since the lifting drive assembly 92 and the horizontal drive assembly 91 are fixed on the mounting block 921, the entire cutter 2 system will also move accordingly, thereby realizing accurate cutting of different positions of the workpiece;

[0040] The electromagnet 7 is clamped at the end of the support rod 6, which not only makes the installation of the electromagnet 7 more stable, but also ensures that it will not be displaced due to vibration or other external forces during use, and also facilitates the replacement of electromagnets 7 of different sizes;

[0041] The top and bottom surfaces of the cutting table 1 are provided with scales, which provide precise references for operators and ensure the accuracy and efficiency of steel plate cutting;

[0042] This laser cutting machine can effectively prevent the steel plate from warping and shifting during the cutting process, ensuring the accuracy and efficiency of cutting and is highly practical.
