Metal-barrel-casing producing machine - has clamp and flanges in fixed position and supporting rollers sliding radially on driving flange and acting separately on shaping rings

摘要

The clamp (10) and the flanges (2-4) enclosing the shaping rings (6,7) are held in a fixed central position. The supporting rollers (63,71) slide in the radial direction on the driving flange (1), and are in groups acting on the rings separately. The clamp can be aligned vertically in a column (11), having internal expanding jaws (12) acting against the casing at one end. There may be an end mounting sliding vertically at the other. USE/ADVANTAGE - For drawing and folding the metal sheet. Simplicity, high output, and low power consumption.
