Quality Research of Metal Parts Produced by Cold Sheet Forming

Sheet metal forming is one of the most popular technologies for obtaining finished products in automotive industries. The main techniques sheet forming: microforming, warm/hot forming, incremental flexible-die Electromagnetic Electrohydraulic Spinning and Shear Spinning, Flow Forming cold forming. One stamping process. In production line Ravne VPS400 1992, we take twenty details looking quality review, surface damage reasons - a little changing tonnage speed. biggest deformation, when velocity slowest don’t have an impact on this radius deformation.
 Firstly, measured all with Contourograph CV-2100 M4. measurement point ten points which or tolerance, these results can be reason why detail damage. These make tact We say recommendation – if will making more process, not damage, but extra process very grown price.
 Second, see steel chemistry alloy elements, elements some mechanical properties steels.
 Our samples enough elasticity, structure recommend taking carbon C, Silicon Si Vanadium V. Si, important machinability tensile as well element essential structure.
 Thirsty, used 3D coordinate measuring machine Mitutoyo SurfaceMeasure 606T, tolerances differences.
 And places lowest from layout, blue color. If made tact’s thickness would evenly gradually. crystalline broke due to excessive thinning.
