Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a radial upsetting device. Background Art

[0002] Radial upsetting is primarily based on the principle of plastic deformation of metals. When a radial external force is applied to a metal blank, the metal is subjected to compressive stress in that direction, causing it to undergo plastic flow, thereby changing the shape of the metal blank and achieving a deformation effect in which the blank gradually increases in radial dimension and decreases in height dimension accordingly. For example, a cylindrical metal blank is placed in a radial upsetting device, and the device applies uniform or specific pressure to the circumferential side of the cylinder. The diameter of the cylinder will gradually increase while the height will gradually decrease, just like the process of kneading a piece of plasticine into a short and fat shape, except that this is for metal materials and is achieved using a specialized device.
