90 degree metal stamping L bracket

Bending - sheet metal under Bending machine die or mould, under the pressure of the first through the elastic deformation, and then into the plastic deformation, in the initial stage of plastic Bending, the sheet is bent, freedom as the upper die or mould pressure on sheet metal, sheet metal and die of V type groove surface gradually tight, radius of curvature and Bending arm also gradually become smaller, Continue to pressure until the stroke is terminated, so that the upper and lower die and plate three points close to full contact, at this time to complete a V bending, is commonly known as bending.

The notice:

1) Small heat conduction, thermal expansion (Austenitic system), so choose cooling but excellent performance of water-soluble lubricating oil.

2) Yield strength and high tensile strength, austenitic system of stainless steel work hardening, easy to produce rebound and transverse damage, so add plant equipment humidity, stiffness and wear resistance must be excellent, usually choose aluminum bronze (PVD, CVD surface treatment).
