Forming Sheet Metal With Rubber

The rubber pad forming sheet metal parts having without stress.

Forming sheet metal with rubber.

Rubber pad forming rpf is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane. Thermoset urethane is an excellent option for forming pads used in hydraulic forming presses. The forming block was machined on a cnc mill. Rubber forminguses a flexible material such as rubber or polyurethane to form a sheet metal work piece.

Hydroform rubber wear pads. Under pressure the forming pad molds the sheet metal into the shape of the die thus forming the part. Often the rubber is incased in a steel container and a work piece is placed over a rigid die. The rubber pads are located above the sheet metal whereas the die is located below the sheet metal.

During the rubber pad forming process the punch deforms the blank and apply large pressure 100 mpa over the blank. Mosites 651 is specially compounded for optimum performance in forming rubber applications. Rubber forming is a sheet metal forming process using flexible punch or die. Rubber is forced all around the work creating.

In this paper finite element method is introduced to analyze rubber pad forming process of aluminum sheet metal. Mosites rubber company has supplied rubber parts to the metal forming industry for a number of years. Maziar ramezani zaidi m. The rubber pads can have a general purpose shape like a membrane.

The work into the rubber. Solid rubber pad forming. Sheet metal forming is a costly manufacturing process that is widely used in different industries. These operations include but are not limited to bladder hydro forming hydro presses fluid forming diaphragm forming bulge forming drop hammer and metal spinning.

Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part. Ripin in rubber pad forming processes 2012. Urethane has a better reputation than rubber when working with metal regardless of thickness. 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.

Sheet metal is secured to the pressing machine after which it s exposed to compressive forces. Rubber pad forming works by sandwiching sheet metal between a die and a series of rubber pads.
