Bending Sheet Metal With A Shop Press

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.

Bending sheet metal with a shop press. 5 16 x 6 length bending length. Weight 34 lbs see more product details. After v shaped bending compression deformation occurred on the inner surface of the bending part of the workpiece and tensile deformation occurred on the outer surface. 14 1 2 x 7 1 2 x 8 estimated.

The v die is usually selected to be 5x to 8x the workpiece thickness. These are h frame presses and are designed as hand operated pumps. Reasonable tolerancing for press brake bending realistic tolerancing can have a profound effect on bending throughput. Attaches to most standard 12 or 20 ton hydraulic shop presses.

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. 12 max attach to most standard 12 or 20 ton hydraulic shop press dim l x w x h in. Actually the term is bending or forming metal in a press brake. Bending principle of sheet metal.

The hydraulic rams makes these presses easy to operate. 01 23 2007 11 12 am 12. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. 3 16 x 12 length.

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. The term you are refering to is called braking metal or a metal brake. Bends up to 90 angles. Theoretically it shouldn t be complicated.

The hydraulic rams makes these presses easy to operate. The eastwood press brake attachment is a precision engineered metal working tool designed to produce accurate variable length bends in angles up to 90 in mild steel and aluminum in widths up to 12 and thicknesses up to 3 8. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. During bending the sheet metal must bridge fully across the v die see figure 2.

In the fab shop the v die width in the press brake limits the size of the flange that can be bent. Brittle materials may require v dies in the 8x to 12x range. Press brake bender attachment bending thickness may vary.
