アップとならず、安価な材料案内手段となっている。According to the present invention, when the angle steel material is inserted into the mold during the second step of the corner cutting of the angle steel material, there are a plurality of guide surfaces corresponding to the plate thickness of the angle steel material. By setting the holding plate to, it is possible to easily shear many angle steel materials continuously. In addition, since the guide surface and the convex portion that correspond to the plate thickness of the angle steel material are provided on the upper side of each guide surface to prevent it from rising, the movement of the angle steel material during shearing can be restricted, and it can be machined with high precision, improving workability. it can. Further, the cost of the conventional die is hardly increased, and the material guide means is inexpensive.
