| Abstract: | The temperature and its distribution of differential temperature deep drawing mould is one of the key technologies for magnesium alloy sheet forming process. It also exerts a tremendous influence on the service life of mould and affects deep drawing effect. A PID temperature control system is introduced, which includes a ringy resistance coil 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. |
