Double Bending Sheet Metal

Geometry of tooling imposes a minimum bend dimension.

Double bending sheet metal.

Custom rolling bending forming steel and waterjet cutting services call 877 754 0900. As a general recommendation 0 005 in. Runs right at the limit of precision flat sheet metal in a job shop environment. We provide a range of metal processing services including tube and steel bending for los angeles california and surrounding areas.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. A 1 degree tolerance on all bend angles. Similarly the more complicated the sheet metal bending process the more material waste may be caused. If you re bending 0 020 thick material use a 0 020 radius.

Bends in sheet metal are manufactured using sheet metal brakes. In the improved design the sheet metal only needs one bending process to complete the bending of the two sides at the same time. The diagram shows one such mechanism. Refer to the chart for values for folder as well as various press brake tooling combinations.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the.

Hansen steel is an expert in metal forming tube bending cutting and fabrication for various markets throughout california. For bent sheet metal variation in the raw material thickness increases the recommended precision to 0 010 in. Since 1984 jorgenson metal rolling and forming has been serving the metals industry in southern california we specialize in rolling of all structural shapes including angle rolling square and rectangular tube rolling pipe rolling channel rolling spiral rolling and beam rolling as well as heavy. When designing parts for laser cutting one should not make holes smaller than the thickness of the material.

In the original design sheet metal requires two bending processes. The average hack requires at least one angled metal part and the best tool to make one is still the good ol press brake. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. The inside bend radius should be equal to the thickness of the material that you re forming.
