12th Tooling Conference & Exhibition - Tooling 2022

The influence of short-time heat treatment on the widely used and commercially available ledeburitic cold work tool steel 1.2379 (X153CrMoV12; AISI D2) was examined in this work. Starting from a soft annealed initial condition, the influence of different austenitizing temperatures and holding times on the metastable microstructural states after heat treatment/hardening was investigated. The...

In hot metal forming processes, the temperature of the forming tool progressively increases under serial production conditions. Water based two-phase lubricants may be applied to cool the forming tool and moderate temperature, in which the liquid agent would evaporate or decompose rapidly with dry matter deposited on the tooling surface during the dwelling time before the forming process...

Multiple cycles of tool dimensional correction during tryout process are one of the most critical aspects in manufacturing of stamping tools, causing significant impact to its production cost. An alternative to reduce tryout time and cost is to perform the dimensional corrections in a virtual model, so that ideally, all the corrections can be done to the simulation before the test of the...
