Temperature Controlling System Design of Non-Isothermal Deep Drawing Mould for Magnesium Alloy Sheet

Abstract

The temperature and its distribution of non-isothermal deep drawing mould is one of the key technologies for magnesium alloy sheet forming process. It exerts a tremendous influence on the service life of deep drawing mould and affects magnesium alloy sheet deep drawing effect. An intelligent PID temperature controller with adaptive ability and self-organization was proposed to control the temperature of non-isothermal deep drawing mould, which included disk-shaped resistance heating coils heating die and blank holder, room temperature water cooling punch of the mould. The temperature control system greatly improved the quality of deep drawing parts of magnesium alloy sheet due to its simple structure, high anti-interference and high controlling precision.
