Title: Cutting method for casting and cutter structure
Inventor: OKUYA YASUAKI
IPC: B02C1/04
Filed: 2001-02-01
Abstract: PROBLEM TO BE SOLVED: To eliminate such defects that, in the conventional cutting devices, as the bottom side of each cutter in one and the other cutting devices has a flat surface and the upper side of the cutter has a curved surface, press force or impact force against a long material between the cutters is applied in a state approximating surface contact, so that the impact force is insufficient, and cutting cannot be performed surely and smoothly or the long material is nipped between the flat surface and the curved surface, which makes the processing difficult; and problems in safety, job management, etc., such as the damage of the cutter, occurrence of a failure factor, deterioration in the life time, deterioration in the working efficiency, are caused. SOLUTION: A cutter in the cutting method for castings using a casting cutting device has a structure where cutters 42, 52 facing each other are provided with edge- side crest parts 44, 54 on their edge sides and with bottom-side crest parts 43, 53 on their bottom sides, respectively. As a result, pressing action and cutting action on an unnecessary casting can be applied between the edge-side crest par and the bottom-side crest part installed in each cutter in one and the other cutting devices, an unnecessary long casting can be cut surely and smoothly, and the cutting size can be almost fixed, thereby making the melting more efficient.
