High Processing

The demand for safer, lighter and more fuel efficient vehicles has led to the market entry of light weight construction, with the use of advanced high strength steels, engineering plastic and light weight metals. Maximum weight savings potential will be limited if these are used in isolation. Chemistry based structural adhesives and foams enable the intelligent use of all three weight saving methodologies to overcome the problems of safety, quality and high processing cost.

Material Parameters

Super high strength steels are used as the importance of lightweight construction increases. They induce a high amount of springback during removal of a tool and this has to be compensated. Previously developed methods of springback compensation [1] have two disadvantages. Firstly springback of a u-shaped profile cannot be compensated in one deep drawing step. Secondly these methods only take the material parameters of one sheet metal batch into account. With varying material properties, problems arise because the tool is especially designed for one sheet metal batch. Therefore the objective of this work is not to compensate springback but to reduce it by a preventive measure which allows the production of a u-shaped profile by one deep drawing step. An additional advantage of the measure, which consists of a geometric change of the punch radii and is defined by several parameters, is that the influence of the sheet metal batch on springback is significantly reduced. This can be realised by a suitable choice of values for these parameters. Apart from this measure a method was developed whereby appropriate values for the parameters can be determined on the basis of a metamodel without the need of individual simulations. By way of example the method is applied to a u-shaped profile, however it can be used for structural components in general.

Tribological System

Today’s sheet metal forming is affected by several trends concerning sheet metal material. The sheet metal forming industry is thereby influenced by the reinforced demand of drawn components made of high strength steels, aluminum or magnesium because of economical and ecological reasons. Besides shifted mechanical properties, changing the sheet metal material influences the entire tribological system and therefore raises questions concerning the suitability of the tool material as well as the lubrication.

Cutting Zone

The formability requirements of high-strength steels are increasing as a result of progressive lightweight construction. An innovative two-stage shear cutting process has been developed in order to meet these requirements. It significantly reduces the edge crack sensitivity of the material in the cutting zone. Studying the effect of worn tool elements on process safety is a key focus for the ongoing improvement of this production process. A production-based tool condition was simulated by creating different cutting edge radii on the active tool elements. Collaring tests showed a reduction of residual formability through wear of up to 65% for high-strength heavy plates (plate thickness > 3 mm).

Abstract Dogal 600 and 800 DP are high-strength steels with a microstructure that contains ferrite, which is soft and formable, and martensite, which is hard and contributes to the strength of the steel. The designation relates to the lowest tensile strength. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming, joining, and surface treatment. Filing Code: CS-160. Producer or source: SSAB Swedish Steel Inc. and SSAB Swedish Steel.

Abstract YS-T 50 to YS-T 140 Steels comprise a series of high-strength, cold-rolled steels designed to meet performance and weight-saving objectives. They are an extension of Youngstown's series of hot-rolled high-strength steels (see Youngstown YS-T Steel, Alloy Digest SA-261, March 1971). The YS-T 50 to YS-T 140 steels have minimum yield strengths ranging from 50,000 psi to 140,000 psi. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and bend strength. It also includes information on heat treating, machining, and joining. Filing Code: SA-331. Producer or source: Youngstown Sheet and Tube Company.
