Folding Sheet Metal Edges
According to the din 8580 series of standards this process belongs to subgroup 4 5 joining by forming and is specified by din 8593.
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. This weakens the aluminium and creates a fracture line. In sheet metal hemming means to fold the metal back on itself. Kwandotechnic please like share and subscribe my ch.
Kwando technic introduce how to homemade a metal pressing tool. This is done by simultaneously folding or pressing the prepared and fitted edges. 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. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.
Before folding sheet metal it is good practice to smooth all edges using a hand file followed by emery cloth. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. 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. Rough sharp edges can be a safety issue and are more difficult to remove once the sheet metal is folded to a 3d shape.
During seaming two sheet metal parts or two edges of the same sheet metal are joined in an interlocking manner. Edge bending processes. Sheet metal of different sizes can be bent an innumerable amount of ways at different locations to achieve desired part geometries. Learn how to bend sheet metal so you.
Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.
