Support using hybrid material for cutting machine of heating type and Nonferrous material assembly of support for cutting machine of heating type}

The present invention relates to a non-ferrous material joints of the support for the heating cutter and the support for the heating cutter using a dissimilar material, and more particularly, when cutting the cutting base material with the heating cutter can stably support the cutting material of the weight from the lower side The present invention relates to a support for a heated cutter using a dissimilar material and a non-ferrous material joining device for a support for a heated cutter while preventing the welding of the molten iron generated during cutting while maintaining the cutting quality.

In general, in the case of steel structure manufacturers, such as shipyards, military equipment manufacturers, when cutting the cutting base material to the required size, after placing a large number of 8 ~ 10mm thick steel plate side by side at 120-150 mm intervals, a wide cutting base to be cut on the upper side The cutting machine is heated as a cutting machine, and the ultra-high temperature cutting machine melts and cuts together a part of the steel plate support supporting the cutting base material at the bottom of the cutting base material.

Accordingly, the steel plate support has to be replaced every three to four months, which requires a lot of cost and time due to the replacement, and the molten iron produced by melting while cutting the cutting base material is fused with the steel plate support, thus being cut after the cutting operation. The iron plate was separated from the steel plate support welded by the molten iron and additional work to remove the molten iron required to reduce work efficiency.

As a conventional technology devised to solve the problems as described above, it will be briefly described with respect to the ceramic support for the heating cutter of Korea Patent Publication No. 2004-80543. 1 is a perspective view showing a state of use of the ceramic support for the heated cutter, Figure 2 is a longitudinal sectional view of the main portion of FIG.

The ceramic support for the heated cutter has a structure in which the ceramic support 2 is vertically coupled to the upper portion of the H-shaped connecting base 10 having the upper insertion hole 11 and the lower insertion hole 12, thereby providing ceramic The cutting material is placed on the upper side of the support (2), and the cutting is performed by an ultra high temperature heating type cutter. The use of a high heat-resistant ceramic material reduces heat damage and enables long-term use, and the molten iron produced while the cutting base material is cut. Since it is not fused to the ceramic support, it is possible to implement an effect of facilitating separation from the cutting base material.

However, even in the case of highly durable ceramic materials with high heat resistance, high thermal shock resistance and high compressive strength, the components change after numerous repeated high-temperature and high-pressure cutting operations, resulting in compressed air used during cutting. Since the phenomenon of melting or melting occurs, a weak brittle ceramic is not suitable for repeated use of a heavy cutting base material for a long time.

In addition, when the ceramic support 2 is not locally cut together with the cutting base material at the beginning of cutting, the cutting surface of the cutting base material is cut at the portion where the cutting surface of the cutting base material and the ceramic support 2 are contacted by local stress concentration and heat concentration.
