Tube hydroforming is a forming method which has several advantages. By using pressure in combination with material feeding it is possible to manufacture products with high structural integration and tight dimensional tolerances. The forming method is especially suited for aluminium alloys which have a relatively low ductility. Finite Element simulations are used extensively in the sheet metal s...

In this paper, we propose a reliability–mechanical study combination to treat the tube hydroforming process (THP). This process consists to apply an inner pressure combined to an axial displacement to manufacture the part. Our goal is the computation of the failure probability of the hydroforming process. Normally, this process is particularly complex and have to be solved numerically. There ar...

forming limit curve (flc) is an important tool for evaluation of formability of sheet metals subjected to different loading. free bulge of aluminume tubes has been investigated numerically to obtain flc. to verify the numerical results one experimental setup has been manufactured which has the ability of controlling the internal pressure and axial feed. in this study, time and zone of bursting ...

Hydroforming process is largely used for the production of tubular parts in various industries, and has advantages such as less weight, higher quality, more strength and fewer production cost compared to the conventional methods of production. The aim of this study is forming a tube-shaped part with a special geometry that has both bulge- and T-zones with tube hydroforming process. The forming ...

During oil-well production, there are often cracks, breaks, and perforation corrosion on the screen pipe that can significantly deteriorate sand control strength. To repair damaged pipes, we developed a technique originating from tube hydroforming, feasibility of was systematically investigated. First, elastoplastic mechanics patch tubes during hydroforming process analyzed to investigate formi...

This paper gives an overview of a deep drawing process by pressurized liquid medium separated from the sheet by a rubber diaphragm. Hydroforming deep drawing processing of sheet metal parts provides a number of advantages over conventional techniques. It generally increases the depth to diameter ratio possible in cup drawing and minimizes the thickness variation of the drawn cup. To explore the...

High-pressure tube hydroforming is a promising method to deform the tubes in various shapes by bulging applying high internal pressure. However, challenges lie process itself, i.e., requires an expensive pump system and brings excessive thinning deformed part section. One option reduce required pressure solve these difficulties, other provide axial feed deformation zone thinning. due higher loa...

Hydroforming patch technology for damaged screen pipes is designed based on tube hydroforming technology, and the methods determining forming pressure range defects are selected according to process. The model established technical demand parameters pipe repair. From mechanical properties of material digital–analog comparison analysis formability, it found that determiners formability (such as ...
