Bending Sheet Metal With A Shop Press

The deformation of these compressions and stretches is greatest on the surface of the material.

Bending sheet metal with a shop press. 12 max attach to most standard 12 or 20 ton hydraulic shop press dim l x w x h in. The v die is usually selected to be 5x to 8x the workpiece thickness. Brittle materials may require v dies in the 8x to 12x range. The term you are refering to is called braking metal or a metal brake.

5 16 x 6 length bending length. Weight 34 lbs see more product details. Press brake bender attachment bending thickness may vary. 3 16 5mm 4 gauge.

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. In the fab shop the v die width in the press brake limits the size of the flange that can be bent. Attaches to most standard 12 or 20 ton hydraulic shop presses. Bends up to 90 angles.

14 1 2 x 7 1 2 x 8 estimated. During bending the sheet metal must bridge fully across the v die see figure 2. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. 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.

Reasonable tolerancing for press brake bending realistic tolerancing can have a profound effect on bending throughput. 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. 3 16 x 12 length. 01 23 2007 11 12 am 12.

The hydraulic rams makes these presses easy to operate. The woodward fab electric hydraulic press has a sheet metal capacity of 10 tons. These are h frame presses and are designed as hand operated pumps. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses.

Bending principle of sheet metal. 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 hydraulic rams makes these presses easy to operate.
