Provider Schuler AG Marketing Bahnhofstr. Fabricators & Manufacturers Association, Intl. Hydroforming tubular components offers several advantages, including: 1. It can be difficult to detect where the curve is exceeded and rupture is possible. This is a process benefit because it reduces the pressure needed to With steel, as YS increases, elongation decreases, and the amount of deformation that the material can withstand before necking and rupturing is reduced substantially. 2135 Point Blvd., Elgin, IL 60123 (815) 399-8700. The term ‘hydroforming’ refers to the metal forming processes in which hydraulic pressure is utilized to deform the material blank. On average, around the cross section, YS gain is the same as the percentage of expansion (5 to 10 This can result in a significant weight penalty, for Sign up and be the first to know about the latest industry news, products, and events! Some material properties in tube hydroforming, such as yield stress or strength, elongation, n value, and, perhaps, r value, are important in varying degrees. 2. form the part, but the end result may not be consistent with the part's functional needs. Assertions that mild steel can be work-hardened to be equivalent to high-strength, low alloy (HSLA) should be scrutinized carefully. Hydraulically stretched material behaves similarly. Many materials can be hydroformed as long as they possess some ductility. As material is stretched it work-hardens and its yield strength [YS] increases. T1 - Tube hydroforming process. Full spectrum hydroforming from Schuler (511.51 KB) White Paper: About Vehicle Structures and Cost (525.35 KB) Lightweight Technologies from Schuler (1.02 MB) Contact. The stretching pattern varies depending on the part shape; its position within the final form cavity; material type and properties; as well as lubrication, surface finish, and several other factors 1. Elongation is the amount that the material stretches linearly prior to necking. However, previous operations such as sheet and tubemaking, bending, and performing introduce thickness variation, which is still evident in the finished part. Tube hydroforming allows engineers to optimize their designs through cross sectional reshaping and perimeter expansion. Lower-elongation material can be used. In addition to the Schuler SMG plant in Waghäusel, Germany, Schuler Incorporated in Detroit is another valuble resource for all matters relating to hydroforming. As one leading industry figure says, “if companies design for hydroforming, then it will be more widely used. hydroforming process. Variable wall thickness affects gas tungsten arc welding stability. • Potential reduction in the final weight of the part. HPH places higher formability demands on material, because of expansion, thus requiring materials with higher elongation and n values to form a given part. HSLA benefits compared to mild steel include tighter control of alloying elements, reduced mechanical property A Seminar Report On HYDROFORMING Guided By ;D.H.Patel Prepared by :Patel Mehul.A Patel Jay 2. In lower-n-value material, stretching concentrates locally and the material bursts more easily. Downloads. The starting round tube must stretch into the final cross-sectional shape after the die is closed. T2 - A reference guide. Another consideration is the minimum material thickness specification required of most components. In several instances, aluminum has been substituted for steel in production hydroforming dies with no change in tools or process conditions. Choosing a material to suit the process might not suit the part function. Easily access valuable industry resources now with full access to the digital edition of The FABRICATOR. Even if special materials are called for, HPH can be a more economical forming method than other options discussed later. However, PSH can be used on special of I.E. N value is the work-hardening exponent that expresses material behavior as it is plastically deformed. Their ability to work with the characteristics of a material and capitalize on its advantages also differ. If the wrong material has been chosen, this often only emerges when the tool is in operational use, potentially resulting in significant extra costs.
