Hengli metal stamping parts, what are the types of stamping and drawing + hundreds of precision processing production equipment

The hardware technicians responsible for the production of Hengli metal stamping parts said that there are several common types when using stamping equipment for metal stamping and stretching. Click: 1. Cylinder stretching process for the stretching of flanged (flanged) cylinder products. The flange and the bottom are both flat, the side wall of the cylinder is axisymmetric, and the deformation is evenly distributed on the same circumference, and the blank on the flange produces deep drawing deformation. 2. Elliptical drawing processing The deformation of the blank on the flange is drawing deformation, but the amount of deformation and the deformation ratio change accordingly along the contour shape. The larger the curvature, the greater the plastic deformation of the blank; conversely, the smaller the curvature, the smaller the plastic deformation of the blank. 3. Rectangular stretch processing Low rectangular parts formed by one stretch. When stretching, the tensile resistance at the rounded corners of the flange deformation zone is greater than the tensile resistance at the straight edges, and the degree of deformation at the rounded corners is greater than that at the straight edges. 4. Mountain-shaped drawing processing When the side wall of the stamping part is inclined, the side wall is suspended during the stamping process and is not attached to the mold. The mold is not attached until the end of forming. The deformation characteristics of different parts of the side wall during forming are not completely the same. 5. Mound-shaped stretching processing The blank deformation of the mound-shaped cover plate during the forming process is not a simple stretching deformation, but a composite forming where stretching and bulging deformation exist at the same time. The deformation of the blank on the blanking surface is tensile deformation (tensile stress in the radial direction and compressive stress in the tangential direction), while the deformation of the blank inside the profile (especially in the middle area) is bulging deformation (both radial and tangential). Is tensile stress). 6. Flanged hemispherical drawing processing When the spherical part is drawn, the blank partly touches the spherical top of the punch, and most of the rest are in a suspended and unconstrained free state. Therefore, the main process problem of this kind of spherical part stretching is the serious thinning of the local contact part, or the instability and wrinkling of the curved part.
