Abstract

PURPOSE: To let a dog contact a screw and determine bending width by step-revolving a cam group together with the cassette screwed with the setting screw as well as to improve the efficiency of bending by the operation signals of the cams.
CONSTITUTION: When a striking piece 22 is moved near the groove 19 of an upper die 13, a dog 23 contacts a set screw 27 and determines a striking length. Next, the end edge of the work is contacted to the striking piece 22 and the upper die 13 is lowered by treading a pedal, whereby the end part is bent. Thence, when a cassette 25 is revolved by a motor 46, a plate cam and one of limit switches LS1-3 go ON and the float 17 of the lower die floats. In this gap, the bent part of the previous process is pressure flattened. When it is step-revolved after this, one of the limit switches goes ON to let the upper die 14 ascend, then the striking piece 22 retreats and at the same time it advances a moving plate 15. Namely, the set screw 27 of this stage strikes against the dog 23, by which the bending width is determined and the work is bent sequare by the upper die 13 and working groove 19.
