Method of manufacturing band blade, method of bending band plate material and apparatus for bending band plate material
WO 1996021543 A1
Abstract
The invention has its object to perform respective processings of forming notches and bends on a portion (62) being processed of a lengthy edged band plate material (61) with high precision. A bending device (31) and a notch forming device (11) are used such that the portion (62) being processed of the lengthy edged band plate material (61) which is passed through an outlet (35) of a die member (32) of the bending device (31) is subjected to notch-forming by the notch-forming device (11), then subjected to bending by the bending device (31) and is finally cut off from a portion which is not processed. When the edged band plate material (61) is pressed against a forming surface (36) of the outlet (35) of the stationary die member (32) by a pressing tool (33) to be bent, a pulled-out amount of the edged band plate material (61) is measured by an encoder (8). A servomotor (7) is operated a number of revolutions which corresponds to a measurement of the encoder (8) to rotate feed rollers (51) to feed the edged band plate material (61) by a predetermined amount.
