Clutch housing for automotive gearbox

The idea

To produce round, hollow sheet metal parts with interior or exterior profiles in a single press stroke, without subsequent mechanical machining.

The process

Whilst a die on a transfer or multi-station press is closing, the translational closing movement in the bottom die is converted into a rotational movement of forming rollers with the required profile by means of racks and gears, and the profile is applied to the round sheet part.

The benefit: Cost saving

The new process delivers precise, round sheet metal parts with a toothed or grooved profile in one operation. The new forming process permits a cost saving of 50 - 70 %.
