Abstract

PROBLEM TO BE SOLVED: To maintain the quality of a cut material by erecting a plurality of cast iron plates on frames at prescribed spaces apart, placing and supporting the material to be cut, and thereby preventing melt at the time of cutting from sticking to the rear face of the material by the return of a plasma arc or an assist gas, even if a cutting torch is right above the plate. SOLUTION: A plurality of cast iron plates, which are each inserted between a pair of brackets 13 oppositely placed on frames 10, 11, 12, are erected at prescribed spaces apart, to form a level block for cutting in accordance with a moving distance of a plasma cutting device. Since a cast iron plate is easier to melt than a steel plate, these cast iron plates 14 for placing and supporting a material to be cut are likely to melt at the time of cutting; hence, the melt from the cutting is provided with a constant relief, enabling the cut material to retain quality. In addition, being erected, these cast iron plates 14 are less susceptible to erosion in the cutting operation of the material and provided with a comparatively long life. If the cast iron plates become unstable in supporting the material to be cut because of increased erosion, they are easily replaceable.

Since the present invention has the above-described structure and operation, the plasma cutting torch or the laser cutting torch is placed directly above the flat plate on which the cutting surface plate is erected during plasma cutting or laser cutting. Even at this time, the quality of the cut product can be maintained without the melt being attached to the back surface of the material to be cut, because the melt at the time of cutting loses the escape area and the melt returns to the plasma arc or the assist gas without returning to the back surface of the material to be cut.

That is, according to the first aspect of the present invention, since the flat plate on which the material to be cut is placed and supported is formed of cast iron, the flat plate is easily melted at the time of cutting, and the melted material at the time of cutting is evacuated. The quality of the cut product can be maintained without losing the quality.

According to the second aspect of the present invention, the covering member made of cast iron is mounted on a flat plate, and the material to be cut is placed and supported on the covering member to cut the covering member. Sometimes it is easy to melt, and the quality of the cut product can be maintained without losing the escape of the melt at the time of cutting.
