Tailored Heating in Hot Forming

The idea for the rese­arch pro­po­sal “Tail­o­red Hea­ting” stems from hot for­ging. The­re, a homo­ge­neous tem­pe­ra­tu­re pro­fi­le is aimed for or only a sec­tion of the com­po­nent is hea­ted (par­ti­al hea­ting). In this rese­arch pro­ject, the pos­si­bi­li­ties for a tail­or-made dis­tri­bu­ti­on of the yield stress are to be inves­ti­ga­ted. This is achie­ved by a tar­ge­ted inho­mo­ge­neous tem­pe­ra­tu­re dis­tri­bu­ti­on. This offers an addi­tio­nal new pos­si­bi­li­ty to con­trol the mate­ri­al flow. A com­plex pre­form can be pro­du­ced by free upset­ting in com­bi­na­ti­on with tail­o­red hea­ting. This has alre­a­dy been pro­ven in a preli­mi­na­ry study.

Con­duc­ti­ve hea­ting, induc­tion and hea­ting with Direct Fla­me Impinge­ment are used to gene­ra­te the tem­pe­ra­tu­re dis­tri­bu­ti­on in three dif­fe­rent mate­ri­als. First, nume­ri­cal inves­ti­ga­ti­ons are car­ri­ed out in order to limit the para­me­ter space and to design the test set­ups. Expe­ri­men­tal inves­ti­ga­ti­ons will then be car­ri­ed out and the three pro­ces­ses will be com­pared tech­ni­cal­ly and eco­no­mic­al­ly. The inten­ded results include the pro­cess win­dow for the tail­or-made dis­tri­bu­ti­on of yield stress for the three mate­ri­als as well as gui­de­lines for the design and appli­ca­ti­on of cor­re­spon­ding hea­ting sys­tems. At the same time, an over­view of the advan­ta­ges and dis­ad­van­ta­ges of the dif­fe­rent hea­ting pro­ces­ses for dif­fe­rent appli­ca­ti­ons is provided.

The pro­cess offers the pos­si­bi­li­ty to pro­du­ce pre­forms wit­hout expen­si­ve spe­cia­li­zed machi­nes and thus allows SMEs in the for­ging indus­try to expand their pro­duct port­fo­lio wit­hout lar­ge addi­tio­nal cos­ts. In addi­ti­on, the­re are pos­si­bi­li­ties for an opti­mi­zed mate­ri­al flow during drop for­ging. In addi­ti­on, SMEs that can manu­fac­tu­re hea­ting equip­ment and simu­la­ti­on pro­vi­ders that sup­port for­ging com­pa­nies in the plan­ning of forming pro­ces­ses also benefit.
