Common product types for metal stamping and drawing processing

With the development of industrial manufacturing, there are a wide variety of metal drawing parts, complex processes, and many changes in shape. The most common drawing parts are cylindrical, elliptical, rectangular, triangular and tapered, etc., such as the more mature stamping process Under circumstances, it can also be manufactured into more complex product shapes. The following is a brief introduction by stamping. What are the most common stretched products? 1. Stretching of cylindrical products, the bottom of the product is flat, the side wall of the cylinder is axisymmetric, and the deformation is evenly distributed on the same circumference, so that The flat blank produces deep drawing deformation. The products in the picture below are customized round pipes, accessories for military products, and stamped strong stretched long pipes processed by our company for customers. 2. The deformation of the elliptical stretch-processed board material blank is stretch 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 shell is stretched to process a low-rectangular piece 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. The most important thing for this product is the molding. The fuel tank molding is a drawing process, the stability of the mold design, while ensuring the stability of the machine tool, the molding process needs to be completed on a hydraulic press. The product in the figure below is a diesel fuel tank processed by our company for customers. 3. The tapered stretch exceeds the stretch processing limit of the stretch processing product, which can be completed after more than two stretches. The products that have been stretched in the depth direction of the front station are re-stretched in the depth direction. The wide flange stretched part is stretched to the required flange diameter when it is stretched for the first time, and the flange diameter remains unchanged when it is stretched later. This product is a car starter cup product processed by our company for customers. Gasoline generator starter cup 4 special-shaped stretched parts. Due to its large depth, complex shape, and large deformation of the blank, it only depends on the local area of u200bu200bthe blank and the punch The transfer of forming force can easily cause local excessive thinning or even rupture of the blank, and it needs to be gradually formed through multiple transitions. 5. 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. Metal drawing parts have different shapes, stamping processing materials are diverse, and their usefulness characteristics are different. When stamping and drawing, the selection of stamping processing materials should meet their own needs, and the mold design and manufacturing process are also different. The drawing parts processed by stamping manufacturers are not limited to those described above. Stretching parts are widely used, not only in industry, but have already popularized people's daily life needs.
