Bending Dies For Sheet Metal

The tube stock is held by force to a fixed form block.

Bending dies for sheet metal.

A wiper like die applies force bending the tube over the form block. If we fail to do this the smaller than required leg will fall into the v opening and our bend will be imprecise. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Using wider dies than necessary can decrease the tonnage required to make a bend.

This is done through the application of force on a workpiece. General purpose 90 degree press brake metal bending punches and dies. Geometry of tooling imposes a minimum bend dimension. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal. So the larger the v opening the larger the minimum leg or flange we must have on a profile. How to bend sheet metal without a brake. Shop 181 sheet metal bending dies at northern tool equipment.

A restrike die operation often follows a drawing or trimming operation. Don t forget that we must have our sheet metal in direct contact with the die shoulders at all times during the bending process. The disadvantage of using wider dies is that the minimum size flange you can bend up becomes larger and so does the inside radius. Compression bending is a tube bending process that has some similarities to edge bending of sheet metal with a wiping die.

The average hack requires at least one angled metal part and the best tool to make one is still the good ol press brake. The diagram shows one such mechanism. However compression also can be used. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.

Bending can be defined simply as a forming operation in which the metal is deformed along a straight axis. Bending is one of the most common sheet metal fabrication operations. Refer to the chart for values for folder as well as various press brake tooling combinations.
