Bending Sheet Metal With A Shop Press

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.

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. 01 23 2007 11 12 am 12. Weight 34 lbs see more product details. Press brake bender attachment bending thickness may vary.

5 16 x 6 length bending length. 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. 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. 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 hydraulic rams makes these presses easy to operate. Theoretically it shouldn t be complicated. The v die is usually selected to be 5x to 8x the workpiece thickness. During bending the sheet metal must bridge fully across the v die see figure 2.

3 16 5mm 4 gauge. Attaches to most standard 12 or 20 ton hydraulic shop presses. 14 1 2 x 7 1 2 x 8 estimated. The term you are refering to is called braking metal or a metal brake.

Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. Actually the term is bending or forming metal in a press brake. The woodward fab electric hydraulic press has a sheet metal capacity of 10 tons. 3 16 x 12 length.

Brittle materials may require v dies in the 8x to 12x range. Bends up to 90 angles. The deformation of these compressions and stretches is greatest on the surface of the material. 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.

These are h frame presses and are designed as hand operated pumps. Bending principle of sheet metal. Reasonable tolerancing for press brake bending realistic tolerancing can have a profound effect on bending throughput.
