Device for pipe buckle folding or upset bulging

摘要

In order to fasten any workpiece between two beads of a folded pipe in a single work operation, a device is proposed, in which the second bead is made on the underside of the workpiece to be fastened simultaneously with the folding of the first bead by a movably arranged guide sleeve. As a result, one work operation can be saved, which means a time saving of approximately 50% in relation to the previous two work operations. <IMAGE>
