Folding Sheet Metal Edges

Bending is one of the most common sheet metal fabrication operations.

Folding sheet metal edges.

Edge bending is used to eliminate sharp edges to provide geometric surfaces for purposes such as joining to protect the part to increase stiffness and for cosmetic appearance. During seaming two sheet metal parts or two edges of the same sheet metal are joined in an interlocking manner. This is done through the application of force on a workpiece. Suitable for folding 3 8 in.

The force must exceed the material s yield strength to achieve a plastic deformation. For sheet metal parts the thickness is the same everywhere. This weakens the aluminium and creates a fracture line. According to the din 8580 series of standards this process belongs to subgroup 4 5 joining by forming and is specified by din 8593.

In sheet metal hems are used to create folds in sheet metal in order to stiffen edges and create an edge safe to touch. Sheet metal usually refers to a thin metal plate with a thickness of 6 mm or less. Design that allows for easier hand folding. This sheet metal folding tool allows you to make uniform folds in sheet metal.

Place the fracture line over the edge of a table and bend the overhang slightly downwards. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Hems are commonly used to hide imperfections and provide a generally safer edge to handle. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. This is done by simultaneously folding or pressing the prepared and fitted edges. Sheet metal fabrication is a cold processing process which is commonly used for punching bending drawing and forming. Depths this sheet metal folding tool features a rust resistant finish four sight holes for proper depth alignment and an 18 in.

Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. Edge bending operations are commonly used in industrial sheet metal processing and involve bending a section of the metal that is small relative to the part.
