Forming Sheet Metal With Rubber

Often the rubber is incased in a steel container and a work piece is placed over a rigid die.

Forming sheet metal with rubber.

The work into the rubber. Rubber forminguses a flexible material such as rubber or polyurethane to form a sheet metal work piece. Rubber is forced all around the work creating. The rubber pad forming sheet metal parts having without stress.

The flat part was punched on a cnc punch press. Rubber pad forming works by sandwiching sheet metal between a die and a series of rubber pads. Many small companies are required to manufacture curved products and shallow parts with fine details in a small lot size which leads to both a higher production cost per detail and a need for multiple tools. These operations include but are not limited to bladder hydro forming hydro presses fluid forming diaphragm forming bulge forming drop hammer and metal spinning.

Sheet metal is secured to the pressing machine after which it s exposed to compressive forces. Mosites 651 is specially compounded for optimum performance in forming rubber applications. Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part. Rubber pad forming rpf is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane.

Urethane has a better reputation than rubber when working with metal regardless of thickness. The rubber pads can have a general purpose shape like a membrane. Solid rubber pad forming. Thermoset urethane is an excellent option for forming pads used in hydraulic forming presses.

Ripin in rubber pad forming processes 2012. The forming block was machined on a cnc mill. Under pressure the forming pad molds the sheet metal into the shape of the die thus forming the part. Maziar ramezani zaidi m.

The rubber pads are located above the sheet metal whereas the die is located below the sheet metal. The punch is act universal tool which is used to provide various different parts. During the rubber pad forming process the punch deforms the blank and apply large pressure 100 mpa over the blank. Mosites rubber company has supplied rubber parts to the metal forming industry for a number of years.

In this paper finite element method is introduced to analyze rubber pad forming process of aluminum sheet metal. Hydroform rubber wear pads.
