Folding Sheet Metal Edges

Kwando technic introduce how to homemade a metal pressing tool.

Folding sheet metal edges.

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. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. Edge bending processes. This weakens the aluminium and creates a fracture line.

Before folding sheet metal it is good practice to smooth all edges using a hand file followed by emery cloth. 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. During seaming two sheet metal parts or two edges of the same sheet metal are joined in an interlocking manner. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.

This is done by simultaneously folding or pressing the prepared and fitted edges. Create a bend with acute angle tooling in the metal 30 is preferable but 45 will work for some circumstances. Learn how to bend sheet metal so you. According to the din 8580 series of standards this process belongs to subgroup 4 5 joining by forming and is specified by din 8593.

One of the most important considerations in sheet metal manufacture is the condition of the sheet metal s edges particularly with regard to the part after manufacture. When working with a brake press hems are always created in a two step process. Kwandotechnic please like share and subscribe my ch. The sheet metal is place between the two working surfaces of the folding bars and placed in a vice.

Rough sharp edges can be a safety issue and are more difficult to remove once the sheet metal is folded to a 3d shape. Sheet metal of different sizes can be bent an innumerable amount of ways at different locations to achieve desired part geometries.
