Title:
非鉄金属鋳物の剪断・折断装置
Document Type and Number:
Japanese Patent JP5748323
Kind Code:
B2
Abstract:
Conventionally, in order to securely catch undesired products such as elongate materials and rod-like materials, strip-shaped cutting edges having inclined faces are formed at the lower end of the swinging cutter apparatus. A number of simply tapered cutting edges provided on the stationary cutter apparatus and the swinging cutter apparatus often have simple cutting edge shapes. Therefore, in some cases, it is difficult to finely crush and break weirs, runners, defective products or the like for casting. An apparatus for shearing and breaking nonferrous castings of the present invention comprises one cutter unit and the other cutter unit disposed in a frame. Each of the one cutter unit and the other cutter unit is comprised of at least an intermediate cutter unit located at the intermediate stage and a lower cutter unit located at the lower stage. Each of the intermediate cutter units is a multi-vertex cutter part formed into a multi-vertex shape by rhombic cutting edges and crucial cutting edges connected to the respective intersections of diagonals of the rhombic cutting edges. The lower cutter units respectively have a concave cutting edge and a convex cutting edge which are engaged with a gap being formed therebetween.
