摘　　要：凸模、凹模、压边圈各自温度及其分布的均匀性是镁合金薄板差温拉深成形加工过程中需控制的关键技术之一,将直接影响镁合金板材差温拉深效果、模具使用寿命。设计了电阻环形线圈加热凸模和压边圈、室温冷却水对凸模进行冷却、PID温度控制器控温的镁合金差温拉深模具温度控制系统。使用表明,该系统反馈及时、温控精度高、模具温度分布均匀,提高了镁合金薄板加热质量。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.
