不锈钢塑性变形时,剧烈硬化。不仅强度极限提高,比例极限提高,而且相对延伸率急剧降低。深拉伸过程中,模具表面形成粘结瘤。粘结瘤的出现,导致拉伸表面划伤,重则工件破裂。随着工业的发展,难成形板料越来越多,研究保护膜具有极其重要的意义。 下面介绍B01—3丙烯酸清漆的应用 在冲压加工前,板料或半成品工件表面用洁净的布擦干净,可以蘸汽油或硝基漆稀释剂擦净工件。如果表面有凸起的沉积物,
Stainless steel plastic deformation, severe hardening. Not only the intensity limit is increased, the proportionality limit is increased, but also the relative extension rate is drastically reduced. Deep drawing process, the mold surface to form a cohesive tumor. Adhesion of the emergence of the resulting tensile surface scratches, while the workpiece is broken. With the development of industry, more and more difficult to form sheet metal, the study of protective film has an extremely important significance. The following describes the B01-3 acrylic varnish application Before stamping process, sheet metal or semi-finished workpiece surface with a clean cloth, you can dip gasoline or nitro paint thinner wipe the workpiece. If there is a bumpy deposit on the surface,
