Professor Metal explains how hydroforming utilizes a punch, a ring, a pressurized forming chamber, and a flexible rubber diaphragm to transform a ductile metal blank into a shaped metal part.
Hydroforming is a manufacturing process where fluid pressure is applied to a ductile metallic blank to form a desired component shape. This process requires hydroforming tools, consisting of a punch made in the shape of the desired part, a ring contoured to fit around the punch and a pressurized forming chamber sealed by a flexible rubber diaphragm.
The typical process cycle starts by placing the metal blank onto a ring that is located over the lower tool (punch). The chamber is then closed over the blank and fluid pressure is applied to the top side of the sheet metal blank. At the same time the punch is pushed up into the blank. The pressure is sufficient to cause the blank to form and take the shape of the punch.
The terms Hydroform and Deep Draw are many times used interchangeably, with Hydroform now being the industry "buzz word" for metal forming. Both processes offer their own unique advantages to metal forming.
