Metal pipe forming equipment and method thereof

Abstract

The invention relates to metal pipe forming equipment, which comprises a mold, primary-secondary punch heads, a feeding compression ring, a base plate, buffer elements, particulate media and vibration-assisted systems. The mold comprises a first half mold and a second half mold; the primary-secondary punch heads comprise upper primary-secondary punch heads and lower primary-secondary punch heads; stepped hole structures are arranged in the primary punch heads; the secondary punch heads are of stepped structures matched with primary punch head stepped holes; the feeding compression ring is arranged in a forming hole of the first half mold; the base plate is arranged on the bottom end of the second half mold and is provided with a through hole; the buffer elements are arranged between the second half mold and the base plate; the particulate media are arranged in a metal pipe to be formed; the vibration-assisted systems comprise hydraulic vibrators which are arranged on the upper surface of the feeding compression ring, the upper surface of one primary punch head and the surface of the mold, so that the forming process of a complex section is simple, the forming process is easy to control, and the problems of fracture, buckling and wrinkling occurred during the forming process are avoided.

Description

technical field [0001] The invention relates to the field of metal forming, in particular to a metal pipe forming equipment and method thereof. Background technique [0002] Lightweight structure and flexible processing technology are one of the general trends in the development of modern advanced manufacturing technology. The lightweight structure can save materials and operating energy, while the flexibility of processing technology can shorten the production cycle of processing tools and reduce production costs. In the fields of aviation, spaceflight and automobile industry, how to reduce the weight on the premise of ensuring the strength and performance of components to achieve the goals of saving materials, saving energy, reducing costs and pollution has become the focus of attention. There are two main ways to reduce the weight of the structure: one is the material way, using lightweight materials to reduce weight, such as aluminum alloy, magnesium alloy, titanium all...
