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.

Reasonable tolerancing for press brake bending realistic tolerancing can have a profound effect on bending throughput. 12 max attach to most standard 12 or 20 ton hydraulic shop press dim l x w x h in. 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. 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.

The woodward fab electric hydraulic press has a sheet metal capacity of 10 tons. Press brake bender attachment bending thickness may vary. During bending the sheet metal must bridge fully across the v die see figure 2. Attaches to most standard 12 or 20 ton hydraulic shop presses.

Theoretically it shouldn t be complicated. In the fab shop the v die width in the press brake limits the size of the flange that can be bent. Bending principle of sheet metal. 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. 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. 01 23 2007 11 12 am 12.

3 16 x 12 length. The v die is usually selected to be 5x to 8x the workpiece thickness. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. The term you are refering to is called braking metal or a metal brake.

The deformation of these compressions and stretches is greatest on the surface of the material. Brittle materials may require v dies in the 8x to 12x range. These are h frame presses and are designed as hand operated pumps. 5 16 x 6 length bending length.

Bends up to 90 angles. The hydraulic rams makes these presses easy to operate. Actually the term is bending or forming metal in a press brake.
