Pressing sintering is completed.
But the pressing sintering being often used at present, it is complicated, and have a single function, the hot pressing for being not particularly suited for workpiece is burnt
Knot processing, for pressing sintering in normal work, while hydraulic cylinder persistently applies pressure to workpiece, heater is also to workpiece
High-temperature heating treatment is carried out, temperature can reach 1700 DEG C or so, since pressing sintering lacks protection operator's personal safety
Function, when hydraulic cylinder declines, if the limbs of operator be located at hydraulic cylinder decline passage zone, hydraulic cylinder can to operation
Member limbs cause certain damage, cause operator to cause danger, and heater to workpiece carry out high-temperature heating treatment when,
Workpiece is fixed by mold or fixture, and the temperature of workpiece can pass to mold or fixture, when the limbs and mold of operator
Or fixture generation misses when touching, and equally will also result in the damage of operator's limbs；Workpiece after being machined by hot pressed sintering, due to
Pressing sintering lacks the function that can be quickly cooled down to the workpiece after processing so that and workpiece can only rely on room temperature to cool down,
Cooling velocity is slow, and the time is long, and efficiency is low, reduces the practical performance of pressing sintering.
