Rubber Press Sheet Metal Forming

Rubber is forced all around the work creating pressure and forming the metal onto the die.

Rubber press sheet metal forming.

A rigid lower die often called a form block provides the mold for forming the sheet metal. Rubber press forming a small rib for a horizontal stabilizer. The flat part was punched on a cnc punch press. For metalworking processes sheet metal is pressed between a die and a forming pad which is connected to a hydraulic press.

The rubber pad forming sheet metal parts having without stress. Fluid pressure forces metal such as aluminum brass alloy steel and stainless steel directly over the die through a diaphragm. Rubber pad forming presses use an enclosed rubber or urethane pad box as a universal female die to form parts over a single un mated tool. Rubber pad forming is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane.

Hydroform presses are incredibly powerful delivering over 10 000 psi to achieve complex forming and tight tolerances. Often the rubber is incased in a steel container and serves as a punch. The rubber pads can have a general purpose shape like a membrane. The fully contained pad box prevents the rubber from extruding outside of the work area during the forming process.

The punch forces the work into the rubber. Before the forming process the blanks are precut to their final dimension. Cost effective way to form sheet metal in addition to the strengthening of the metal 3 verson hydroform bladder presses 4. Solid rubber pad forming process.

It is easy and requires application of rigid container fillet with solid rubber pad. Solid rubber pad forming. A beckwood 400 ton rubber pad forming press making 5 different parts in one cycle. The tool is placed unsecured onto the bed bolster and downward pressure is applied.

Rubber pad forming is a deep drawing technique that is ideally suited for the production of small and medium sized series. The blank of sheet metal work piece is placed on the die. Under pressure the forming pad molds the sheet metal into the shape of the die thus forming the part. Impresa uses the hydroform process to produce large sophisticated parts including fuselage frames.

A work piece is placed over a rigid die. Rubber forming rubber forming uses a flexible material such as rubber or polyurethane to form a sheet metal work piece. Alternatively they can be machined in the shape of die or punch.
