Abstract

The reported estimation calculations have determined the kinetics of temperature changes in the model clamp‒dielectric matrix‒upper electrode‒punch‒sintered ring product‒lower electrode‒punch‒stand. This has made it possible to determine the temperature of the control volumes of the product and tooling in a random period. The experiments have confirmed that the estimated values of temperature in the upper and lower layers of the sintered product are rather similar and differ little from actual ones. Specifically, it has been established that the sintered product concentrates 24 % of the thermal energy, which is released throughout the entire unit (press-tool‒product). Under a conductive heating method, it is very important that the maximum temperature in the zone of the sintered product should be reached in the shortest period.

 It has been shown that during exploitation the material of a mold under conditions of electric sintering is exposed to the thermocyclic and thermomechanical influence. The tooling components have different resistance to wear: a resource of the isolated insert is 20 cycles of sintering, of electrodes–punches ‒ 50 cycles. This allows us to argue that it is necessary to choose a material for the components of a mold, which could meet the following requirements:

– the minimal heating of the tooling elements, thereby ensuring its structural reliability and operational adaptability (a holder, a matrix, a stand);

– the maximum heating of the chain: an upper electrode‒punch‒needle‒the sintered product‒a lower ring electrode-punch, thereby contributing to the accumulation of heat in the contact area between the components of the mold and a would-be product.

The above measures lead to the increased structural strength of sintered products, as well as to the optimization of control over would-be technological operations and prompt registration of important experimental data.

Thus, there are reasons to assert the possibility of the targeted adjustment of temperature fields through the preliminary calculation and selection of the tooling materials based on the thermal-physical characteristics. The application of a given mathematical model is an effective way to resolve the above issue
