摘要：
A stripping device for enlarging an opening in sheet material and possibly for initially forming and then enlarging the opening. A hydraulically operated cylinder has a cylinder housing around it. A piston in the cylinder is connected to move a shoe that is guided on the cylinder housing. A clamping jaw is attached to the cylinder housing. An axially displaceable stripping jaw is connected to the piston either by a rod on the piston or that jaw is attached on the shoe and moves with the shoe. The shoe may have a plurality of spaced attachment points for the stripping jaw. There may be an extension of the piston on which the stripping jaw is carried or on which an additional sripping jaw is carried. There may be an extension of the cylinder housing on which an additional clamping jaw is carried.
