稳定温度场下建筑初模热切割可实现技术研究

Research on the Technology of Thermal Cutting for Raw Building Model under Steady Temperature Field

详细叙述了多轴控制的建筑初模型面热切割机的研发过程。采用MACH3数控软件控制切割机三维运动,采用一种恒温控制系统实现稳定温度场下热丝与泡沫体表面接触。该系统能够按设定加热目标温度,完全由硬件电路实现对接触区域温度的实时测量与控制,改变了热切割泡沫的单一方式,增加了泡沫体型面切割功能;同时减小了切割丝热变形现象,扩展了泡沫产品的成形种类。该切割机在实际建筑初模热切割中的应用效果很好。

The development of cutting machine with multi-axis control for raw building model under steady temperature field was described. The cutting machine was integrated the MACH3 NC software to control the three axis. Temperature of wire and move rotation of blank were controlled by wireless remote unit. It can be used to cut fluting on both inside and outside foam surface and can cut irreg- ular curved surface. Distortion caused by cutting thread＇s thermal deformation is reduced and shaping category of foam product is ex- tended. It is shown that the application effect of this cutting machine for raw building model is very good.
