Metal stamping, drawing and forming process-hardware

What are the types of metal stamping and drawing forming processes? As one of the main stamping processes, compression-stretching is widely used. Various thin-walled parts with cylindrical, rectangular, stepped, spherical, conical, parabolic and other irregular shapes can be made by the stretching process. So today, the hardware is here to share with you: What are the types of metal stamping and drawing forming processes? When using stamping equipment for metal stamping and drawing processing, there are the following 6 types: 1. Cylinder drawing processing: with flange (Flange) Stretching of cylindrical 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 flange blank 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 drawing process low rectangular parts formed by one-time drawing. 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 until the end of the forming. The deformation characteristics of different parts of the side wall during forming are not completely the same. 5. Mound-shaped stretching processing: The deformation of the blank of the mound-shaped cover plate during the forming process is not a simple stretching deformation, but a composite forming in which stretching and bulging deformation exist simultaneously. The deformation of the blank on the blank 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 contour (especially the zhong center area) is bulging deformation (radial and tangential) All are tensile stress). 6. Flanged hemispherical drawing processing: When the spherical part is drawn, the blank partly contacts 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. The above is the introduction of the hardware author. I hope it will be helpful to you.
