Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a movable side metal mold positioning method in a section cutter by which a movable metal mold moving origin positioning at the time of cutting a C-channel material and a channel material is highly accurate and stably performed and cost reduction can be performed and device therefor. SOLUTION: The positioning to a moving origin is performed for a movable metal mold 25 by setting an upper limit stopper 53 of an elevating/lowering member 55 which is normally energized upward by an energizing member 57 so that the movable metal mold 25 placed on the elevating/lowering member 55 may be located at the moving origin. When the movable mold 25 is lowered, the elevating/lowering member 55 lowers against the energizing member 57. When lowering force is eliminated, the positioning to the moving origin is performed for the movable side metal mold 25 because the elevating/lowering member 55 returns to an upper limit stopper location by retaining force of the energizing member 57. When cutting working is performed by raising the movable metal mold 25, the movable metal mold 25 is detached from the elevating/lowering member 55 and rises.  When the rising force is eliminated after the working, the movable metal mold 25 lowers up to the elevating/lowering member 55 and the positioning to the moving origin is performed for the movable metal mold 25.
