長尺複合刃物の製造方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method of manufacturing a long composite cutter such as a veneered rotary knife, which does not require a particularly large press machine, and which does not require a step on the base metal member. The present invention relates to a method for manufacturing a long composite cutter that is crimped and rolled without requiring machining.

形を示す。As shown in FIG. 5, the long composite cutter is composed of a base metal 1 made of structural carbon steel or the like, and a blade metal 2 made of tool steel or the like. In FIG. 5, the shape indicated by the dashed line indicates the shape of the blade material before performing necessary machining such as cutting or grinding.

材を製造していた。As shown in Fig. 6, the conventional method for manufacturing the material for this long composite cutter is to heat a base metal member 1a and a blade member 2a with a rectangular cross section to the temperature required for forge welding, overlap them, and press them together under high pressure. The blade member 2a was pressed into the base metal member 1a using a press, and then reheated and rolled to produce a material for a long composite blade.

しかしながら、上記従来の長尺複合刃物の製造方法では
、まず第１の方法として記述したプレス圧着による製造
方法においては１例えば５０００トン級の高圧プレス機
械が必要となり５極めて高価な設備を必要としていた。Furthermore, the proposal described in Japanese Patent Publication No. 62-36812 is that, as shown in FIGS. 8 and 9, the blade 2 is crimped onto the base metal 1 to form the blade edge member 3, and then removed after heat treatment. Attached is a manufacturing method in which the member 1b is integrally joined by laser beam welding etc. 6 [Problem to be solved by the invention] However, in the above-mentioned conventional method for manufacturing a long composite cutter, the method described as the first method is The manufacturing method using press crimping requires a high-pressure press machine of, for example, 5,000 tons, and requires extremely expensive equipment.
また、ロール圧延時には再度１１ｏＯ〜１２００℃に加
熱する必要がありエネルギーコストが高くついていた。Further, during roll rolling, it was necessary to heat the material again to 11oO to 1200°C, resulting in high energy costs.
さらに、台金部材と刃金部材の圧着は台金部材に刃金部
材を押し込み、両者が平坦になるまで加圧するので。Furthermore, when crimping the base metal member and the blade member, the blade member is pushed into the base metal member and pressure is applied until both become flat.
刃金の幅及び厚みにむらが出るという欠点があった。There was a drawback that the width and thickness of the blade were uneven.

いた。また段部は平板より削り出すことになるので材料
の歩留りが極めて悪いという欠点があった。Next, in the manufacturing method described as the second method, since it is necessary to provide a notch step in the base metal member, a cutting process for step processing is required, and the number of processing steps is large. Furthermore, since the stepped portion is cut out from the flat plate, there is a drawback that the yield of material is extremely low.

た。Furthermore, although the manufacturing method described in the above-mentioned publication has the effect of reducing deformation and internal stress caused by the compression heat treatment of the cutting edge member only in one direction (up and down), it requires a large laser beam device and the manufacturing cost is high. It had the disadvantage of becoming

The materials are placed against each other and the contacting parts are welded to form a material block. Further, at this time, if the abutting angle between the blade member and the base metal member is about 80 degrees, the adhesion between the two after pressure contact will be even better.
