Filed: 1990-02-15
Abstract: PURPOSE:To provide the edging press which can prevent the generation of twists in a press material subjected to edging by providing a twist preventive member on the upstream side in the line direction of buckling preventive rolls. CONSTITUTION:Twists are sometimes generated in the press material 5 subjected to the edging by the presence of mechanical clatters in the press or the presence of a nonuniform temp. distribution or the unbalance of a component distributions in the press material 5, etc. If, however, the twists tend to be generated in the press material 5, the press material 5 first comes into contact with the twist preventive member 8 provided near the upstream in the line direction 1 of the buckling preventive roll 6 and the twist of the part in contact with this member is restrained. Since the press material 5 is a continuous body, the restraining force on the part in contact with the member 8 spreads to the entire part and the generation of the twist in the part of the press material 5 edged between metallic molds 4 and 4 is prevented.
