項記載の連続折曲げ機。[Claims for Utility Model Registration] A continuous folding machine in which an upper mold 3 comprising mold parts 10 and 11 each having a desired shape on a plurality of longitudinal ridges is rotatably attached to the lower part of a ram 2. In a bending machine, driving means 12 for forcibly rotating the upper mold 3
, 13, and corresponding to each mold part 10, 11, a stopper 15, which prevents each mold part 10, 11 from further rotating beyond its working position.
16 are provided on the lower surface of the ram 2, and these stoppers 15 are provided on the circumferential surface of the upper mold 3 as the upper mold 3 rotates.
. Of the stoppers 15 and 16, one is a fixed stopper consisting of a recess formed on the lower surface of the ram 2, and the other is located at the rear of the upper mold 3, and the engaging portion 20 is inserted into the rotation locus of the cam projection 14. A continuous folding machine according to claim 1, which is formed in a movable stopper that can be freely retracted. The drive means for forcibly rotating the upper mold 3 is comprised of a gear 12 connected to the upper mold 3, a rack gear 13 meshing with the gear 12, and a drive source for forcibly reciprocating the rack gear 13. Continuous bending machine as described in Scope section.
