Industry information

During the deep drawing process, different regions of the blank exhibit different deformation characteristics. The central part of the billet eventually becomes the bottom of the simple part, and this area is basically not deformed, which can be regarded as the non deformed zone.

sheet metal manufacturingis, in fact, omnipresent in daily life. Metal sheets serve as essential components in numerous applications. For instance, they are used in the fabrication of chimneys, iron drums, oil tanks, ventilation ducts, elbows, and small heads. After undergoing processing, metal sheets of various specifications are required to meet different demands.

Choosing a suitable metal stamping parts supplier is crucial for ensuring product quality, cost control, and production progress. It can be evaluated from multiple aspects such as supplier strength, products, and services. The following are specific points:

Seamless structure: The deep drawing process can shape a uniform and seamless shape, greatly reducing potential weak links in the final product and significantly improving the overall quality and reliability of the product.

The deep drawing coefficient, which is the ratio of the billet diameter D to the workpiece outer diameter d, is an important indicator for measuring the difficulty of deep drawing. The smaller the deep drawing coefficient, the greater the degree of deformation, and the easier it is for the billet to crack, often requiring multiple deep drawings to complete the forming of the workpiece.

The deep drawing die is mainly composed of a convex die, a concave die, and a edging ring. Under the action of the press, the convex mold gradually presses the circular billet into the concave mold, and its shape and size determine the inner surface shape of the workpiece after deep drawing. The concave die is the outer contour limitation of the blank deformation, and its inner wall shape is adapted to the outer surface of the deep drawn part.
