The Metal Stamping parts produced by stamping factories are characterized by relatively small material thickness, large structural dimensions, complex shapes, high requirements for dimensional accuracy and appearance quality compared to ordinary thin sheet stretching parts. When forming automotive metal stamping parts, the deformation of various parts on the blank is complex and significant, and the stress is uneven, making it prone to surface defects such as rebound, wrinkling, cracking and stamping lines. Let me briefly explain the impact line:

The impact line is caused by the displacement of the contact point between the material and the punch during the forming process of metal stamping parts, as well as the different resistance during material forming. The bottom sheet metal moves through the top of the punch, and its external motion static conflict is transformed into a dynamic conflict resulting in the formation of impact traces. The reason for the occurrence of stamping lines is generally due to differences in resistance during the sheet metal forming process, or significant deformation of the bottom surface of the parts. Secundo legem deformation is tendentiae partium metallorum, i scire potest quod distributio deformationis tensilis secundum periferiam vacuum in deformationis zonae stampionis metallorum non est aequa. Area rotae vacuum minor est quam illud rotae anguli, ita deformationis fortis deformationis quae ad deformationem compressionis in angulo recto est minor quam illud in angulo rotundi.

A causa inequalitatis convex mollis ad metallum folii, variatio modi occurrit in movimento metallis subter folii, ab initio turbatio usque ad liniam impactionis quae occurrit dum profunda procedura drawing is. Vires formatio est totum continuum, et movementum lineae impactionis continuum crescit dum continuum movementum metallis folii. Maximum movementum lineae impactionis occurrit in summo puncto convex molditae supra movementi, quod est quando formatio finita est.

Problema influentium linearum crescere apparuerit et facta est mala apparentiae linearum in processione partium stampionis metallorum. Hoc difficile multas difficiles facit in fabricationem design et reparationem pro productione potentiae partium stampionis metallorum.
