This machine adopts mechanical and electrical integration design, and it has concise and elegant appearance, it is the precise device used to test manufacturability of metal thin sheet and banded material, according to GB/T 4156-2007, it can inspect metal’s plastic deformation of metal’s thin sheet and banded in the testing, it also accords with in GB5125-2008< Method for deep drawing cups testing of non-ferrous metals> for testing the characteristics of non-ferrous metal sheets.
For cupping testing, using a certain specifications of steel ball or globular punch, put pressure on the specimen which perimeter has 10kn clamping force, until the specimen produce penetrating cracks, at this time punch press-in depth(mm), it’s the sheet of cupping value, this cupping value is used to judge plastic deformation properties of material.
The testing of deep drawing cups make the thin-sheet and strip’s wafer
Sample(Ø60 )pressing on clamping ring and dies, under momentum-effect of punch applied, generated radially extending and bending plastic deformation, then drawing into a cylindrical cup one time, it is used to assay the material's anisotropic as the symbol of earing rate.
