The Spun Drum Head

2015-11-21


The blank plate and the mandrel spin together, fed and forced by the roller, so that the blank plate can cling to the mandrel and be local deformed point by point. This is the stamping and forming method.

Fix the blank plate on the mould of the spinning machine. The blank plate spins following the machine tool spindle, in the meanwhile, forced by the spinning roller or stick so that it can have the partial plastic deformation. During the feeding force by the spinning roller and the plate’s self spinning, the partial plastic deformation expands to the whole surface of the plate step by step and the plate clings to the mandrel so that the spinning process is finished.

Drum head by cold forming has the accurate dimensions and the stable quality. It is free from the rough surface and oxidation by the heating. It has good appearance. And don’t worry about the changes of material characteristics.

When the stamping closes to the little R of the drum head, the oxidation film falls off and it has the clathrate trace. It is caused by the plastic forming. It’s not the defection.
