The clamping end faces of the two shorter segments of the U-shaped clamping plate 631 are wedge-shaped structures. A plurality of lead screws 632 are respectively arranged on the lower side of the second bottom plate 2 corresponding to the plurality of sliding plates 62.

[0033] It should be noted that the left and right sliding plates 62 on the front and rear sides are initially in a state of moving away from each other. When the raw material steel plate is placed on the first bottom plate 1 by an external feeding device and pushed from left to right to the middle position of the first bottom plate 1, the front and rear lead screws 632 connected are controlled to rotate by the double-shaft motor 634. The front and rear lead screws 632 on the right side drive the front and rear lead screws 632 on the left side to rotate synchronously through the transmission belt 635. The front and rear lead screws 632 on the left and right sides respectively drive the corresponding front and rear sliding plates 62 to approach each other. At this time, the left and right sliding plates 62 on the front and rear sides respectively drive the corresponding U-shaped clamping plates 631 to approach each other, so as to achieve the effect of jointly clamping the steel plate by the front and rear two U-shaped clamping plates 631. Then, control the two pneumatic push rods 71 on the left and right to jointly drive the pressing plate 72 to move downward until the pressing plate 72 presses the middle part of the steel plate. The clamping and limiting unit 6 and the pressing unit 7 cooperate to clamp the side wall of the steel plate and press the middle part of the steel plate at the same time, so as to realize the limiting of the steel plate cutting waste and the cut panel respectively. It can clamp the side wall of the steel plate and press the middle part of the steel plate at the same time, so as to realize the limiting of the steel plate cutting waste and the cut panel respectively, and avoid the problems that the cut part may collapse and the position may shift during the cutting of the steel plate by the traditional cutting equipment, thus affecting the cutting quality.

[0034] Refer to Figure 3-Figure 5 and Figure 7 The auxiliary limiting part 64 includes L-shaped support plates 641 symmetrically installed at the upper ends of the front and rear U-shaped clamping plates 631, and U-shaped limiting plates 642 are symmetrically installed at the opposite ends of the front and rear L-shaped support plates 641.

[0035] Refer to Figure 2-Figure 4 and Figure 7 Refer to

[0036] Refer to Figure 4 、 Figure 7 and Figure 8 The laser cutting part 83 includes an electric slider 840 slidably installed on a rectangular return rail 81, and the four corners of the rectangular return rail 81 are rounded structures. An installation plate 831 is installed at the lower end of the electric slider 840. A waist-shaped sliding groove 832 is opened at the lower end of the installation plate 831. A waist-shaped sliding plate 833 is slidably installed in the waist-shaped sliding groove 832. A connecting disc one 834 is arranged at the lower end of the installation plate 831. An annular sleeve 835 is arranged on the lower side of the connecting disc one 834. The outer wall of the annular sleeve 835 is movably attached to the side wall of the auxiliary limiting plate 73. Connecting discs two 836 are arranged at both the upper and lower ends of the annular sleeve 835. A laser cutting head 837 is installed through the middle of the annular sleeve 835. The connecting disc two 836 and the upper end of the annular sleeve 835 are jointly provided with two front and rear circular sliding holes 838. Support sliding rods 839 are slidably installed in both the front and rear circular sliding holes 838. The upper ends of the front and rear support sliding rods 839 penetrate through the connecting disc one 834 and are fixedly connected to the waist-shaped sliding plate 833.

[0037] When the front and rear U-shaped clamping plates 631 jointly clamp the steel plate, the front and rear U-shaped clamping plates 631 will drive the corresponding U-shaped limiting plates 642 to approach each other through the corresponding L-shaped support plates 641 respectively. At this time, the relative ends of the front and rear U-shaped limiting plates 642 are mutually attached and pressed tightly, and a loop-shaped limiting groove is formed by the front and rear U-shaped limiting plates 642 and the auxiliary limiting plate 73. After the pressing plate 72 presses the middle part of the steel plate, control the electric slider 840 to drive the mounting plate 831 to slide along the loop-shaped slide rail 81. The mounting plate 831 drives the front and rear support slide bars 839 to slide along the loop-shaped slide rail 81 through the waist-shaped slide plate 833. The front and rear support slide bars 839 drive the laser cutting head 837 to slide along the loop-shaped slide rail 81 through the annular sleeve 835. During this period, when the electric slider 840 drives the mounting plate 831 to slide to the corner of the loop-shaped slide rail 81, since the annular sleeve 835 is located in the loop-shaped limiting groove formed by the front and rear U-shaped limiting plates 642 and the auxiliary limiting plate 73 at this time, and the annular sleeve 835 drives the waist-shaped slide plate 833 to perform sliding compensation along the waist-shaped slide groove 832 through the front and rear support slide bars 839, thus realizing the effect of the laser cutting head 837 sliding along the loop-shaped limiting groove. When the laser cutting head 837 slides along the loop-shaped limiting groove, while controlling the laser cutting head 837 to cut the steel plate, control the polishing disc 843 to rotate through the second motor 842, so as to simultaneously realize the effects of laser cutting the steel plate and polishing the cutting surface. The cutting and polishing unit 8 cooperates with the clamping and limiting unit 6, and can control the laser cutting head 837 to perform laser cutting work along the loop-shaped limiting groove formed by the front and rear U-shaped limiting plates 642 and the auxiliary limiting plate 73, and polish the cutting surface at the same time, effectively improving the cutting efficiency and cutting quality.

[0038] Refer to Figure 4 、 Figure 7 and Figure 8 As shown in, the lifting and avoiding unit 9 includes the front and rear support round rods 91 installed at the lower end of the lower connecting disc two 836. Universal wheels 92 are installed at the lower ends of the front and rear support round rods 91, and compression springs are sleeved on the parts of the front and rear support slide rods 839 between the connecting disc one 834 and the upper connecting disc two 836.

[0039] Refer to Figure 2 、 Figure 3 and Figure 5, the ejector part 55 includes rectangular support plates 554 installed at both the front and rear ends of the U-shaped top plate 52. The two front and rear rectangular support plates 554 are respectively slidably connected to the corresponding rectangular through holes 53. A U-shaped frame 551 is commonly installed at the lower ends of the two front and rear rectangular support plates 554. The upper end of the longer section of the U-shaped frame 551 is connected to the bottom plate 2 through a plurality of compression springs. A first motor 552 is installed at the lower end of the bottom plate 2 through a motor base. The output shaft of the first motor 552 is connected to a cam 553, and the cam 553 is in rolling contact with the lower end surface of the U-shaped frame 551.

[0040] After the laser cutting work and the cutting surface polishing work of the steel plate are completed, the two front and rear lead screws 632 connected are controlled to rotate in opposite directions by the double-shaft motor 634. The two front and rear lead screws 632 on the right side are driven by the transmission belt 635 to drive the two front and rear lead screws 632 on the left side to rotate synchronously in opposite directions. The two front and rear lead screws 632 on the left and right sides respectively drive the corresponding two front and rear sliding plates 62 to move away from each other and return to their original positions. At this time, the two left and right sliding plates 62 on the front and rear sides respectively drive the corresponding U-shaped clamping plates 631 to move away from each other, disengaging from the steel plate cutting waste. Then, control the two pneumatic push rods 71 on the left and right to drive the pressing plate 72 to move upward together until the pressing plate 72 moves upward and returns to its original position, disengaging from the panel obtained by cutting the steel plate.

[0041] Then, control the convex block to rotate through the first motor 552. The cam 553 will push the U-shaped frame 551 to move upward. The U-shaped frame 551 drives the U-shaped top plate 52 to move upward through the two front and rear rectangular support plates 554. The U-shaped top plate 52 drives the steel plate cutting waste to move upward to a position higher than the panel obtained by cutting the steel plate. Then, the cutting waste is taken out by an external material taking device, and the panel obtained after cutting the steel plate is taken out by an external material taking device. During this period, the steel plate cutting waste will push the corresponding universal wheels 92 to move upward. The universal wheels 92 drive the lower connecting disc 836 to move upward through the two front and rear support round rods 91. The lower connecting disc 836 drives the laser cutting head 837 to move upward through the annular sleeve 835. At this time, the two front and rear support sliding rods 839 respectively slide into the corresponding circular sliding holes 838, so as to achieve the effect of driving the laser cutting head 837 to adaptively avoid. It should be noted that when controlling the laser cutting head 837 to cut the steel plate, under the action of a plurality of compression springs, the two front and rear support sliding rods 839 will respectively protrude out of the corresponding circular sliding holes 838, so as to achieve the effect that the two universal wheels 92 always roll on the upper end surface of the steel plate.

[0042] Repeat the above operations to repeat the laser cutting work on the steel plate. The clamping and limiting unit 6, the pressing unit 7, the cutting and polishing unit 8, the ejecting unit 5 and the lifting and avoiding unit 9 cooperate to limit the cutting waste and the cut panel of the steel plate respectively, avoiding the problems that the cut part may collapse and the position may shift during the cutting of the steel plate by traditional cutting equipment, which may affect the cutting quality. Moreover, the laser cutting work and the cutting surface polishing work can be carried out on the steel plate simultaneously along the rectangular limiting groove formed by the two U-shaped limiting plates 642 and the auxiliary limiting plate 73 in the front and back directions, effectively improving the cutting efficiency and quality. And when taking out the cutting waste and the cut panel in sequence, the effect of driving the laser cutting head 837 to adaptively avoid is achieved.
