MACHINE FOR BENDING THIN PLATE, METHOD OF BENDING THIN PLATE USING THE MACHINE, AND BENT PRODUCT OF RESIN-MADE THIN PLATE MIXED WITH WOOD POWDER

摘要

PROBLEM TO BE SOLVED: To provide a machine ensuring bending of a thin plate made of a resin mixed with wood powder and a method of bending a thin plate.;SOLUTION: The machine 1 is equipped with a table 3, a female member 7 which has a V-shaped groove 7A and is to be mounted with a thin plate 10, a heating device 20 for heating the plate 10 and a male member 6 pressing the plate in a heated state to bend along the bent portion 10A. A small-diameter portion for pressing the portion 10A toward the bottom of the groove 7A is formed at the tip of the pressing portion 6B of the member 6. The machine ensures good bending work because a thin plate is bent by pressing a thin plate toward the bottom of a V-shaped groove with the tip of a pressing portion of a male member while heating the plate at a specified temperature. Therefore, a corner portion along a V-shaped groove can be formed reliably without cracks even when the plate is made of a resin mixed with wood powder.;COPYRIGHT: (C)2004,JPO
