摘要
通过实例,介绍了一种半空心型材一模双孔挤压模结构,提出了一种能保证悬臂强度的替代式模芯结构。详细描述了这种结构的有关参数的选择与优化方法,包括挤压机能力的确定、模孔的布置,同时采用计算机模拟软件进行分析和对比,确定分流孔的布置、下模焊合室结构和工作带的选择。同时还介绍了模具强度的校核方法。结果表明,这种针对半空心型材的一模双孔挤压模结构是有效的,可以提高生产效率并降低成本,值得推广。
Through a actual case,a new structure for the semi-hollow Al-profiles was introduced.The structure named substituted type to solve the cantilever strength was present.And the selection and the optimization of structure parameters were described in detail,including the determination of extrusion machine ability,the layout for the die holes,use of computer simulation software for analysis and comparison to determine the arrangement of portholes,the structure of chamber in female die,the selection of bearing belt etc.The method of checking the die strength was introduced.It is shown that the structure with twin cavities for semi-hollow profiles is effective,the structure can greatly improve the production efficiency and reduce the cost.It is worth promoting.The purpose is to provide reliable data and reference for the further research and development of this technology on the extrusion die with multi-cavities in a die.
