Abstract

The invention discloses a processing method for thin-wall barrels. The method comprises the steps such as setting-out, blanking, circle-shearing, milling processing, wrapping, welding, welding seam grinding, stretching and forming, explosive forming and the like. The processing method is simple and convenient to operate, a plurality of thermal-treatment tempering processes are not needed, processing steps are simplified, and time consumption is reduced, so that the processing efficiency is improved; the processed thin-wall barrels are high in dimension consistency and are high in precision, so that the production cost can be reduced; besides, the processing method further has relatively wide applicability, and can be used for processing other similar thin-wall barrels.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and manufacturing, in particular to a processing method for a thin-walled cylinder. Background technique [0002] In the field of mechanical processing, for the processing of thin-walled cylindrical parts, the traditional processing methods mainly include the following two methods: one is multiple sets of drawing dies, gradually stretching and forming, and the other is powerful spinning forming. Step by step stretching of multiple sets of drawing dies not only requires a reasonable number of heat treatment and tempering processes between the processes to eliminate tensile stress, but also prevents oxidation from tempering during the heat treatment and tempering process, which is extremely difficult. Moreover, the workpiece has a certain amount of springback after stretching, and it is difficult to control the consistency of the size, resulting in a decrease in the precision of the fi...
