Hardware drawing parts, several types of drawing process to share with you? 【Hardware】

Hardware drawing parts are one of the more important types of stamping processing, and they are widely used. Various thin-walled parts with cylindrical, rectangular, stepped, spherical, conical, parabolic and other irregular shapes can be made by the stretching process. And what are the general types of metal drawing parts? Xiaoshuo understands with you: 1. Step stretch processing: Re-stretch the left-side initial stretched product to form a step-shaped bottom on the right side. The deeper part is deformed in the early stage of stretching, and the shallower part is deformed in the later stage of stretching. It is easy to induce shear stress and deformation on the sidewall of the step change part. 2. Reverse stretching processing: Reverse stretching is a kind of re-stretching of the workpiece that was stretched in the previous process. The reverse stretching method can increase the radial tensile stress and can achieve better results in preventing wrinkles. It is also possible to increase the stretch coefficient of re-stretching. 3. Thinning and drawing processing: Different from ordinary drawing, thinning and drawing is mainly to change the thickness of the tube wall of the drawing part during the drawing process. The gap between the convex and concave dies is smaller than the thickness of the blank. When the straight wall part of the blank passes through the gap, it is under a large uniform compressive stress. While the wall thickness becomes thinner during the stretching process, the wall thickness deviation of the container is eliminated and the surface of the container is increased. The smoothness improves accuracy and strength. 4. Panel drawing processing: Panel products are sheet metal stamping parts with complex surface shapes. In the drawing process, the deformation of the blank is complicated, and its forming properties are no longer simple drawing forming, but a composite forming in which deep drawing and bulging exist at the same time.
