Description

[0001] Automatic saw machine [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic sawing machine, and more particularly, to an automatic sawing machine which automatically cuts a circular cutter in a predetermined size according to a setting value, .

Generally, the metal plate material is usually cut by a band-saw machine or oxygen cutting. However, the band-saw machine is advantageous for cutting a curve, and it is difficult to cut stainless steel or an iron alloy having a high hardness. It is very slow and not suitable for cutting processes such as sheet metal.

Therefore, circular saw blades different from the cutting method of the metal plate material by the band saw machine method as described above have been mainly used recently. Such a circular saw blade is equipped with a cemented carbide tip, or the whole is made of high speed steel, The cutting speed is very fast and the cutting surface has a surface with a good surface roughness as a whole, thereby improving the quality of the product.

The circular saw blade as described above has a problem in that the entire surface of the metal plate and the both side surfaces are frictioned during the process of use, shortening the life span and making the cut surface rough. Thus, the method of sandwiching the wedge between the cut portions is selected, And the structure is improved so that the surface roughness of the cut surface becomes a fine surface with the extension of the service life.

One example of such a technique is disclosed in Document 1 below.

Patent Document 1 discloses a structure in which a top plate is provided on an upper surface, and a guide for guiding and guiding a metal member to be cut is provided on the rear surface of the upper plate; A cutting angle adjusting means installed on one side of the upper plate so that the upper surface thereof has a height corresponding to the upper surface of the upper plate; Cutting means provided on the cutting angle adjusting means for cutting the metal member; And an auxiliary top plate movably installed on the main body so as to be connected to the other end of the top plate when the base is laid flat.

However, in the conventional technique as described above, the plate material is configured to be moved by an operator, and it takes much time to cut and move the plate material to the fixed circular saw blade. When the skill of the operator is lowered, And there is a problem that the worker is injured by the circular saw blade in the course of work.
