Provided is a multipoint stretch forming apparatus enabling individual clamping control for manufacturing a curved panel, wherein a plurality of stretching units are positioned at both sides at a lower position of a supporting frame in forward and backward directions, and each of the stretching units is independently and individually controlled. Further, since the distance between the right and left stretching units is adjustable in accordance with the size of punch modules and the size of a curved panel to be formed, the precision formation of both wide and narrow curved panels/shapes is possible. Through this technical constitution, an atypical curved panel is formed more efficiently and the loss of panel material is remarkably reduced. |
