Flanging processing technology of cylindrical drawing parts

Cylinder-shaped drawing parts are a relatively common metal drawing parts, and they are also widely used. Some customers have special requirements for stretched parts, such as flanging, which can meet the special needs of the product. Stretch parts processing plants need to fully understand the flanging processing of stretch parts. Precision-More than 10 years dedicated to customized processing services for precision metal drawing parts. Next, I will introduce the flanging process of the stretched parts below. Cylinder stretching parts with flanging include narrow flanging cylinder stretching parts and wide flanging cylinder stretching parts; narrow flanging cylinder stretching parts are stretching parts with a small total flanging width. When the parts are stretched several times, because the flanging is narrow, they can be stretched according to the non-flanging cylinder first, and then the flanging process is performed to form the required narrow flanging appearance, in order to make the flanging better Forming, in the latter two processes of stretching, a tapered die and a tapered press ring can be used for stretching, and the tapered flanging can be freed, so that the radial stretching deformation of the flanging area can be reduced when the part is reshaped. It is beneficial to avoid edge splitting. When the wide-flanged cylindrical stretched part needs to be stretched several times, the flanging specification must be equal to the flanging specification of the stretched part for the first stretch, and the flanging specification will remain unchanged during the following stretches. , It only relies on the migration of a part of the cylinder to reach the specifications of the stretched part. Because in the subsequent stretching process, even if the flanging part causes little deformation, it will cause very large tensile stress in the force transmission area of u200bu200bthe cylinder wall. In turn, the bottom end section is cracked.
