Rubber pad forming sheet metal.

Rubber pad forming is a sheet metal forming process in which a rubber pad is used to deform metal sheets. Solid rubber pad forming. As an european leader in the technical rubber parts borflex masters the whole manufacturing chain from specific compounds r d for rubber pads production which are particularly adapted to the most accurate stampings.

Rubber pad forming rpf is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane. It is easy and requires application of rigid container fillet with solid rubber pad. The tool is placed unsecured onto the bed bolster and downward pressure is applied. 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.

The flat part was punched on a cnc punch press. The fully contained pad box prevents the rubber from extruding outside of the work area during the forming process. It s not designed to cut sheet metal. Under pressure the forming pad molds the sheet metal into the shape of the die thus forming the part.

Thermoset urethane is an excellent option for forming pads used in hydraulic forming presses. A form of deep drawing rubber pad forming is a technique used in the manufacturing industry to manipulate sheet metal by pressing it between a series of rubber pads and a die. Rubber press forming a small rib for a horizontal stabilizer. The operations are 1 the guerin process and 2 hydro forming guerin process the guerin process uses a thick rubber pad or other flexible material to form sheet metal over a positive form block as in figure 20 28.

The forming block was machined on a cnc mill. Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part. The rubber pad is confined in a steel container. The rubber pad forming sheet metal parts having without stress.

How rubber pad forming works. The rubber pads can have a general purpose shape like a membrane.
