Multi-layer pipe quick liquid-filled forming method and system

Abstract

The invention relates to a multi-layer pipe quick liquid-filled forming method and system; according to the invention, a technical problem that plates in two layers or more than two layers are formed by using pressure uniformly loaded by a liquid and the liquid filling speed can be increased can be solved; pipes in a plurality of layers are sleeved together and clamped by upper and lower half molds; no pretreatment is needed between the pipes in the plurality of layers; additional oil guide cylinders are sleeved at the right ends of the pipes in the plurality of layers; a left pushing head is inserted into the left ends of the pipes in the plurality of layers; a right pushing head is inserted into the additional oil guide cylinders; the pipes in the plurality of layers, the left pushing head, the right pushing head and the additional oil guide cylinders form a liquid chamber; through the additional oil guide cylinders, a forming medium is filled into the liquid chamber; after the liquid chamber is full of the forming medium, the right pushing head is moved to seal the right ends of the pipes in the plurality of layers; the forming medium is filled into the liquid chamber in the pipes from the left or right pushing head so as to supercharge; meanwhile, the left pushing head and the right pushing head are axially moved and fed to the pipes so as to ensure the sealing of the pipes; and the pipes in the plurality of layers are in close contact with each other due to the effect of the forming medium, so that the layers of a formed pipe are also closely combined with each other.

Description

technical field [0001] The invention relates to a multilayer pipe forming method and system, in particular to a multilayer pipe liquid-filled forming method and system. Background technique [0002] In the fields of aircraft, spacecraft and automobiles, reducing weight to save materials and energy during operation is a long-term goal pursued by people, and it is also one of the trends in the development of modern advanced manufacturing technology. The use of composite structures such as multi-layer pipe structure parts can achieve multiple functions. For example, the parts have both strength and certain functions such as anti-corrosion performance. Pipes with good corrosion resistance such as aluminum alloy can be used. [0003] Nowadays, there are also many composite pipes that must be prepared before forming, so that the multi-layer pipes can be tightly combined before forming, and then formed using a rigid punch and die; but this forming method is difficult to guarantee ...
