Metal stamping parts processing

Metal stamping parts drawing as one of the major stamping process, application is very broad. By drawing process can be made into all kinds of cylindrical, rectangular, step, spherical and conical, parabola and other irregular shape thin-walled parts. 1, with hemispherical tensile flange processing: spherical parts drawing, blank and punch ball at the top of the local contact, most of the rest in the impending untrammelled free state. Therefore, this kind of main technology of spherical parts drawing part of the problem is that local contact serious thinning, wrinkle or curved surface part of instability. 2, the flange drawing processing: the tensile flange part of the product will be shallow drawing processing. Its stress and strain is similar to compressed flange. Due to tangential compressive stress, wrinkle easily, so the forming limit is mainly restricted by compression wrinkling. 3, the edge stretching processing: flange department of process drawing products before stretching processing Angle, this kind of material has good plasticity processing requirements. 4, deep drawing processing: more than drawing machining limit tensile products, need to go through repeated stretching can complete two or more times. After the former location depth direction tensile processing products, in the depth direction tensile processing again. Wide flange (tensile, the first stretch stretches when required by the flange diameter, behind, stretching with flange diameter stays the same. 5, conical stretching processing: h/d> 0. 8日,α= 10度; ~ 30度; Deep taper, due to large depth, deformation degree of blank is bigger, only on billet the local area of contact with the punch forming force, easy to cause excessive billet local thinning, and broken, need after many transition gradually forming. Stretches ladder stretching method was that the billet step transition, forms its ladder with cone shape of the cut, the last expansion form a cone. Ladder transition metal stamping parts including drawing number, process and steps of drawing of cylinder is the same.
