Common product types of stretch parts

Stretching parts are a kind of metal stamping parts, and their applications are also very extensive. For stretch parts processing plants, there are also various types of stamping parts processed, including cylindrical, elliptical, tapered, rectangular, and so on. These are the more common types of stretch parts. Of course, for some products, stretch parts with more complex shapes are required. Next, Precision will introduce you to the main types of metal drawing parts. 1. Cylindrical drawing parts The bottom end of the product is flat, and the outer wall of the barrel is symmetrical in the middle, and the deformation is evenly distributed on the same circumference, so that the plate or strip can be stretched. 2. Elliptical stretched parts The deformation of the blank is a stretched deformation, but the amount of deformation and the deformation ratio are relatively transformed along the shape of the contour. The larger the curvature, the greater the plastic deformation of the blank; on the contrary, the smaller the curvature, the smaller the plastic deformation of the blank. 3. Rectangular stretched parts When stretched, the tensile friction resistance at the arc of the flange deformation zone exceeds the tensile friction resistance at the straight side, and the deformation level at the arc exceeds the deformation level at the straight side. 4. Cone-shaped stretched parts Stretched products that exceed the limit of stretch processing need to go through multiple stretches before they can be processed. The stretched parts that have undergone the stretching process in the previous process are re-stretched in the subsequent process. The wide flange stretch piece 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. 5. Because of the large degree of stretching, the appearance design of the special-shaped stretched parts is more complicated, and the material deformation is large. Only the total area of u200bu200bthe material and the mold touches the forming force to transmit the forming force, which is very easy to cause the embryo material to become soft due to too much part. Even cracking, it takes many stretching processes to form slowly.
