挤压铸造设备的研究进展与发展趋势

Research and Development of Squeezing Casting Equipment

挤压铸造设备是完成挤压铸造工艺的主要平台,挤压铸造设备的性能直接影响挤压铸造产品的质量。本研究针对VV型结构、HV型结构、HH型结构挤压铸造压力机介绍了挤压铸造机的关键技术和发展状况。在外围系统部分,主要介绍了挤压铸造模具和浇注系统的研究进展。随着挤压铸造工艺日趋完善和应用范围不断扩大,今后挤压铸造设备上的发展方向主要是大吨位挤压铸造机的研制、浇注系统的改进、模具温度控制这三个方面。

The performance of squeezing casting（SC） equipment directly determines the quality of SC products.The key technologies and development status of SC press machine were analyzed taking machines of VV type,HV type and HH type as the objectives.For the peripheral equipment of SC,the development of the die and the gating system was mainly presented.With the expansion of SC technique application,the development of SC equipment will focus on the R D of large tonnage SC press machine,the improvement of gating system and temperature control of the die.
