Modelling, Analysis and Development of Progressive Die for Seat Rail

Progressive dies are highly used in batch productions where product variety is low. The progressive die is also called follow on die. It performs series of basic sheet metal operations. There are two or more stations and work piece is gradually shaped to final product through passing each of these stations. The ‘progression’ (advance or pitch) is linear travel of the strip stock at each press stroke and it is equal to the infestation distance. In the present paper an attempt is made to develop a new progressive die, which used in making seat rail of an automotive four-wheeler vehicle of Toyota, to optimize the use of material. So, the cost of progressive die reduces without losing its quality. For modelling CATIA and for analysis ANSYS are used.

Folgeverbundhybridschmieden eines Querlenkers*/Hybrid forging process within progressive dies of a suspension arm – Lightweight structural construction and heat subjection of hybrid forged parts

Folgeverbundhybridgeschmiedete Bauteile haben großes Potenzial im Leichtbau. Am Beispiel eines Querlenkers wird der Vorteil des Hybridschmiedens in Struktur- und Stoffleichtbau betrachtet. Zusätzlich zeigt die Betrachtung des Wärmeeintrags, dass beim nachträglichen Vergüten das Potenzial des Stoffleichtbaus nicht gefährdet wird.   Components manufactured by hybrid forging in progressive dies have a high potential for lightweight construction. The example of a suspension arm shows the advantage of hybrid forged parts creating new possibilities for structural and material lightweight construction. Additionally, it is demonstrated that the heat subjected to hybrid forged parts during the subsequent hardening process does not threaten the potential of material lightweight construction.

The Application of KBE on Stamping Process Design

UGNX6.0 is used as the development platform by its UG/KF development tools, fusing feature and knowledge together, so as to realize the process associated with the geometric design knowledge and stamping process design. Based on the features of stamping process, the classification of stamping process knowledge has been studied. With the object-oriented method, the rule-based and instance-based technology for expressing and acquiring the stamping process knowledge is discussed. Based on this, the stamping process model driven by knowledge has been established. A bending sheet was taken as an example in introducing the designing process of progressive die based on UG_PDW. The process arrangement was mainly introduced, and the bending part feature recognition and modeling were all elaborated and related examples were given in the paper. It showed the importance of the CAD technology in designing of relatively complex progressive dies.

This paper takes UGNX6.0 as the development platform, by using its UG/KF development tools, fusing feature and knowledge together, so as to realize the process associated with the geometric design knowledge and stamping process design. Based on the features of stamping process, the classification of stamping process knowledge has been studied. With the object-oriented method, the rule-based and instance-based technology for expressing and acquiring the stamping process knowledge is discussed. Based on this, the stamping process model driven by knowledge has been established. It showed the importance of the CAD technology in designing of relatively complex progressive dies. Based on the knowledge engineering process designed, the degree of intelligence stampings process design has been enhanced, design quality and efficiency has been improved, and the dependence of the process design experience of designers has been reduced.
