This technique can produce relatively complex shapes. . The technique has not conceptually changed until our times but it has notably evolved in the cutting capacity in terms of thickness and length, we passed from the manual one big scissors , to the bench one, with a fixed blade and the other manually lowered by apposite levers up to the industrial ones, where the used driving force has evolved like in all other machines hydraulic, steam, electrical. In this paper, an integrated process simulation and die design system developed at the University of Miskolc, Department of Mechanical Engineering will be introduced. Fundamental was, in 1857, the introduction of the Bessemer converter Figure 1 used in the industrial production of steel starting from the melted cast iron produced in the blast furnace. In this way, participants wishing to review these fundamentals have prepared themselves in an optimal way for the high-level technical presentations of the main event. This paper will introduce a simulation based die design concept implemented in tool-making for sheet metal forming with particular interest on car manufacturing.

In this latter activity, the AutoForm Engineering GmbH is a strategic partner of the department for several years. Results showed the same crash performance for both materials, although the aluminum part cost 40 percent less. Production volume, however, remains limited. Metal stamped parts provide maximum stability and durability to the vehicle on account of which their utilization is widely preferred by the commercial vehicle manufactures complementing market growth. The amount of punch force necessary for forming is thereby continually increased up to the lower dead center of the punch. However, tightening access to finances is affecting the Brazilian manufacturing growth hamper demand in the country. It is a flexile process by which a wide variety of shapes can be produced using standard die sets.

As a result, the new alloys have been designed to support the superplastic forming of large, thin-walled aluminum sheet components. The key to achieving weight reduction in a given part or assembly is not just to choose lightweight and high-strength materials, but also to develop advanced forming methods. The industry is characterized by companies employing stamping technology and third-party contractors. The automotive industry faces with very contradictory demands and requirements: better performance with lower consumption and less harmful emissions, more safety and comfort; these are hardly available simultaneously with conventional materials and conventional manufacturing processes. Vice versa they obtained a reduction of the iron oxides in practically pure iron, which at the end of the process appeared as a spongy mass mixed with scales and slags. The unique United Stated method was to use a continuous assembly production line to speed up car production at lesser direct labor costs between the years 1910 to 1921. This is expected to drive the market growth in the U.

In India and Far East there were other techniques based on the heating in a melting pot of particularly pure iron ore, glass and carbon. Increasing use of metal parts in cars and other vehicles has affected the market growth positively. The metal working is an ancient art. Soft iron was only hot workable, then arousing particular problems for the attainment of thin thicknesses. The solution methodology was based on explicit time integration.

In the first part of the article developments from this last stage will be presented which had fundamental in-fluence on processes and products. These requirements are the main driving forces behind the material and technological developments in sheet metal forming: application of high strength steels, low weight light alloys and the appropriate non-conventional forming processes are the main target fields of developments summarized in this paper. The reason that superplastic forming has remained a niche process over the last two decades is because it has traditionally shown slow cycle times in the range of half an hour per part produced. The use of bending process in manufacturing spare parts and vehicle components is expected to grow over the forecast period. Metal on the outside of the bend is stressed in tension beyond the elastic limit.

The figure illustrates the deep drawing process. During the recent years, due to the rapid development in Finite Element modeling, as well as the rapid evolution of computer techniques, numerical modeling has become an important everyday tool not only for process analysis and process optimization but for die design and rapid die manufacturing, as well. Vehicle manufacturers outsource the stamping process to third-party vendors in order to minimize cost. Various generations of high strength steels e. In addition, it provides high strength with associated durability, crash, stiffness, and structural-stiffness for an overall improvement in performance. Aluminum sheet, in particular, has lower formability at room temperature than typical sheet steels. The manufacturing can also be designed within a single unit with the preheat, blowforming, and annealing stages occurring in one line.

Nowadays, rising demand for concept car, automobiles with latest technology, aesthetics of vehicles with safety concern, high strength and light weight results technological advancement in sheet metal forming and innovative material development like different grades of high strength steels and lightweight aluminium alloys. The process has been extended also to other uses like the attainment of small tubes with subtle thicknesses but also of pots, washing basins etc. Perforating is one of the type of piercing process, in which a die is intended to make small holes on the work piece several times, leaving a pattern of small holes on the desired part for various purposes. The material is placed on the die, then positioned in place using stops and gages, and held in place with hold-downs. Statements Efficiency, precision, light weight design … …have to go hand in hand in car body part production. The process of deformation begins with a blank, a quantity of metal in some basic form that will undergo the change in shape.

In 1980s, there was another significant model in the nature of manufacturing. Thus, the United States car companies took away the leadership spot in the automobile industry from the European countries mentioned above. Bending is generally used to produce simple curved surfaces rather than complex ones. Recently, Hydro launched three new aluminum alloys for the superplastic forming of aluminum sheet, mainly for the automotive market. An integrated approach to forging and heat treatment will also be illustrated.
