Bending Sheet Metal With A Shop Press

Commonly used equipment include box and pan brakes brake presses and other specialized machine presses.

Bending sheet metal with a shop press.

During bending the sheet metal must bridge fully across the v die see figure 2. 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. Sheet metal and plate bending looks simple enough but the truth is that it s often the most complicated process on many metal fabrication shop floors. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.

Creating a 22 gauge sheetmetal box from scratch. Theoretically it shouldn t be complicated. Bends up to 90 angles. The term you are refering to is called braking metal or a metal brake.

3 16 5mm 4 gauge. Actually the term is bending or forming metal in a press brake. 5 16 x 6 length bending length. 2 metal sheet bends in a single descent of the press brake this last method is the most reliable since it is manufactured completely to the client s specifications and allows us to test the metal sheet of the client before finishing the tool and to be able to test its result.

The v die is usually selected to be 5x to 8x the workpiece thickness. Reasonable tolerancing for press brake bending realistic tolerancing can have a profound effect on bending throughput. Weight 34 lbs see more product details. Video tutorial includes cutting the sheetmetal template and bending the pieces on my 24 grizzly box pan b.

12 max attach to most standard 12 or 20 ton hydraulic shop press dim l x w x h in. To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to selectively. 3 16 x 12 length. Attaches to most standard 12 or 20 ton hydraulic shop presses.

14 1 2 x 7 1 2 x 8 estimated. Brittle materials may require v dies in the 8x to 12x range. In the fab shop the v die width in the press brake limits the size of the flange that can be bent.
