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 ...

 Nowadays, light weight and high strength metals are being used in various industries such as automotive and aerospace. Using aluminum-magnesium alloys is an efficient way to reduce the weight of a specific part. These alloys have poor formability in room temperature thus they should be formed at elevated temperature. Warm hydroforming and hot metal gas forming are conventional methods to form ...

Product design in the early stages requires a more quantitative process to ensure that simulation study's outcome will meet expectations. The purpose of this study was determine whether manufacturing software package could effectively evaluate and validate conceptualised blank tooling manufacture sizeable complex- shaped aluminium alloy aircraft panel using die sheet hydroforming. Blank tool co...

Development of new technologies and combined with creativity and innovation, plays the fundamental role in developing of any community′s value. Thus, in this research the design and production of hydroforming device was introduced. One of the best and most efficient technologies in the world of metal forming is wind turbine blade producing with hydroforming method which seems as an innovative m...

Hydroforming is one kind of plasticity working, which can be used to increase the diameter, to change the geometry, or to expand the outer walls of cylindrical shells or tubes. The forming principle of hydroforming is by using a die to constrain the outer geometry of a tube and then pumping high pressure oil into the inner tube, so as to force part of the tube to flow into the die cavity. In or...

The hydroforming technology can realize overall forming of large storage tank’s bottom, but the quality is affected by many technological parameters. In view wrinkling and cracking defects integral bottom in hydroforming, a multi-objective optimization model established for process parameters including pre-expansion pressure, hydraulic blank holder force, fillet radius holder. Based on finite e...
