This drum pressing machine and flanging machine mainly applicable to all kinds of pressure vessel heads of cold and hot forming.

Dished end drum pressing and flanging machine unit

Flanging and stamping forming compared with many advantages. The equipment is lighter weight, smaller tools and lower cost, higher efficiency (equipment volume higher), and bigger ratios of radius to thickness. Thin dished end with flanging method do not crease (longitudinal no, but sometimes a circumferential wrinkles). When the dished end ratios of radius to thicknessmore than with flanging method won't wrinkle.flanging forming can be made into a diameter of twenty m's dished end, therefore has become an important modern pressure container manufacturing equipment.

 

Flanging is for two steps, the first step will dished end circular blank sheet placed on the drum pressing machine using corresponding on the Yin Yang side automatic clamping and rotation, and gradually point pressure into POTS sphere, and then spinning flanging on the flanging machine, until meet the size requirements so far. Flanging is fast, usually only 7 to 10 minutes.
