Abstract

PURPOSE:To obtain a titled device in which a stopper occupies automatically proper positions successively by inputting sequence of processing of each bent part, size of shoulder width of V part of the lower die, plate thickness, bending angle etc. a computer incorporated in a press brake, and calculating all elongation by the computer. CONSTITUTION:The body of press brake consists of frames 3 erected on left and right sides and a long upper apron 5 fixed on them. The device works plate material by a punch 5a and a die 7a while moving a lower apron 7 vertically by a hydraulic cylinder. When performing bending work of the plate material, the elongation of material is calculated basing on the above-mentioned data inputted in a computer, and a stopper 15 on the stretch 13 positions the material backward and forward by a motor and an encoder. Under this condition, locking distance of a lever 31 and a locking piece 29 are controlled by a tachogenerator 81, a motor 77, a detector 63 etc. and eventually, locking distance between the punch 5a and the die 7a is controlled.
