Abstract

PURPOSE: To enable to cut a plate structure of a complex shape by a simple device with no generation of a hanging, a return, and a bending etc., by means of causing the upper cutter to be lowered against the pushing force of reversed pushing members at the shearing time.
CONSTITUTION: This device is composed of an upper mould 2 which forms a cavity of a plate structure 1 of a complex shape and a lower mould 3. The upper mould 2 is separated into two at the dividing position, and one becomes to a pushing cutter 4 and the other becomes to an upper cutter 5, and each of them is holded by a holder 6 of pushing cutter and a holder 7 of the upper cutter respectively. And, the lower mould 3 is also separated into two at the dividing position, and the side corresponding to the pushing cutter 4 of the upper mould 4 becomes to a lower cutter 17 and the side corresponding to the upper cutter 5 becomes to a reversed pushing cutter 18, and each of them is holded by a holder 20 of a lower cutter and by a holder 21 of a reversed pushing cutter. By such constitution, even in a plate structure 1 of a complex shape, a fine cut having no hanging, return, and bending etc. can be performed with good efficiency.
