PROBLEM TO BE SOLVED: To enhance machining precision by accurately positioning a workpiece easily and stably regardless of the width of a workpiece and the shape of a striking face of the workpiece. SOLUTION: In a drawing device in which a workpiece W is bent by dies P, D consisting of a punch P and a die D mounted on the upper and lower tables 9, 10, an auxiliary stopper 1 is installed on the side of the main stopper 3 arranged in the rear side of the lower table 10 and is made capable of projecting/retracting against the main stopper 3. In this case, the projecting/ retracting mechanism of the auxiliary stopper 1 is composed of a rack and pinion motor mechanism. COPYRIGHT: (C)2004,JPO
