Comparative Analysis of Powerful Spinning Process And Drawing Process for Cylindrical Parts Low-carbon steel cylindrical thin-walled parts with a bottom are widely used in the energy industry. There are usually two processing methods: drawing and powerful spinning. The following is a comparative analysis of the spinning process and the drawing process for thinning cylindrical parts: (1) Powerful spinning process: By applying local pressure to the rotating blank through rollers, the blank deforms point by point in the gap between the roller and the mold, achieving wall thickness reduction and shape formation. The products produced by powerful spinning have higher dimensional accuracy, can achieve higher wall thickness uniformity and dimensional accuracy, and are suitable for cylindrical parts with high-precision requirements. The products produced by powerful spinning have better surface quality and lower surface roughness, making them suitable for parts with high surface quality requirements. The powerful spinning process is suitable for cylindrical parts with high precision and high strength requirements, such as in high-end manufacturing fields like aerospace and automobiles. (2) Drawing process: The blank is stretched and deformed by using a die. By controlling the stretching force and the shape of the die, the blank is deformed simultaneously in the axial and radial directions to achieve the required dimensions of the cylindrical part. The cylindrical part after stretching has good plasticity, but its strength is relatively low. This is because during the stretching process, the metal flow is relatively uniform and the internal stress distribution is relatively uniform. The surface of the stretched product may have marks and requires subsequent processing. The drawing process is suitable for cylindrical parts with high requirements for plasticity and relatively low requirements for dimensional accuracy In actual production, we should select the processing technology based on the production situation of the product.
