Bridge bearing masonry pads handrail bearing pads pads between steel beams girders grates columns pads between bridge and roof beams and substructures shock and vibration isolation heavy equipment mounting pads railway tie pad applications pads underneath concrete vaults 18. The pressure over rubber membrane is controlled through out the forming cycle with max pressure up to 100 mpi as a result the friction at the punch cup interface increases this increase. Rubber pad forming is a sheet forming process in which one or more product related molds. Sheet metal forming 2 810 d.

This allows the pressure that forms the work part to be increasedto around 100 mpa 15 000 lb in2 thus preventing wrinkling in deep formed parts. The form block is then machined according to each customer s unique specifications. Rubber bearing pads has been used in. In bending and embossing of sheet metal the female die is replaced with rubber pad hydro form or fluid forming process.

A beckwood 400 ton rubber pad forming press making 5 different parts in one cycle. The difference is that it substitutes a fluid in place of the thick rubber pad as in figure 20 29. Rubber pad forming rubber pad forming rpf is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane. 9 boothroyd dewhurst and knight.

Sheet metal parts are deformed by the stamping process. The rubber pads can have a general purpose shape like a membrane. 1 where several process steps like forming cutting or embossing can be carried out in one process step. Cooper sheet metal forming ch.

During the rubber pad forming process the punch deforms the blank and apply large pressure 100 mpa over the blank. Our rubber pad forming process begins with form block a material made from resin board aluminum or plastic. The rubber pad forming process is also called as guerin process. Hydro forming process hydro forming hydro forming is similar to the guerin process.

The rubber pads used in the process are made of hard urethane with dimensions of 43 inches by 51 inches each about 1 5 inches thick. Although a large number of machine components are made from sheet metal with a thickness of up to 2 mm production of such parts is not economically viable in traditional dies which are designed for mass production. Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part.
