The segmented tables 2 can be supported by vertical plates 3, reinforced by reinforcement seats 4, and buffered by segmented grooves 5 to prevent flame damage, thereby reducing the impact of flame penetration and improving the quality of subsequent cutting of the steel plates as much as possible.

[0024] Example 2, refer to Figure 3 A high-efficiency straight strip cutting machine, a connecting frame 6 is provided on the top of the machine frame 1, and angle plates 7 distributed at equal distances are welded on the outer wall of one side of the connecting frame 6, a screw rod 8 is screwed on the inner wall of the bottom of the angle plate 7, and a pulley 9 is rotatably connected to the outer wall of one end of the screw rod 8, and an inclined pressure plate 10 is welded on the outer frame of the pulley 9.

[0025] In this embodiment, when the straight cutting head 17 is continuously cutting, the connecting frame 6 will continue to move forward, thereby driving the pulley 9 and the inclined pressure plate 10 to move continuously. Since the pulley 9 and the inclined pressure plate 10 can always fit the steel plate under the rotation of the screw rod 8, the steel plate can be continuously compacted to prevent the steel plate from warping upward, thereby ensuring the flatness of the steel plate.

[0026] Reference Figure 3 A guide rod 11 is fixedly connected to the outer wall of the top of the inclined pressure plate 10, and the guide rod 11 is slidably connected to the inner wall of the angle plate 7.

[0030] Reference Figure 1 A base 19 is installed on the bottom outer wall of the frame 1.

[0031] Working principle: The steel plate can be placed directly on multiple segmented platforms 2, and then with the cooperation of the horizontal electric guide rail 12 and the vertical electric guide rail 13, the cross arm 14 can be driven forward. At this time, the straight cutting head 17 will continuously cut the steel plate. The segmented groove 5 inside the reinforcement seat 4 can extend the spacing of the straight cutting head 17, thereby buffering the damage caused by the flame. During this process, the pulley 9 and the inclined pressure plate 10 can always fit into the steel plate and compact the steel plate to prevent the steel plate from warping upward.
