RESEARCH ON THE USE OF ADVANCED PULTRUSION TECHNOLOGY TO ASSIST IN FORMING EQUAL-SECTION SPIRAL STRUCTURE PRODUCTS

为了提高等截面螺旋结构制品的成型效率及自动化程度,对其成型工艺进行了研究。针对该结构制品的截面尺寸及其预制体的工艺特征,进行了成型参数设计和工艺试验,最终采用先进拉挤工艺(ADP)制备了等截面的预制体,并将预制体扭转填充至螺旋槽中真空固化成型了相关制品。研究表明,采用ADP辅助成型等截面螺旋结构制品的自动化程度高、致密性好,制品表观质量有所改进。

In order to improve the forming efficiency and automation of the equal-section spiral products,the forming process was studied.For the structural product section size and the process characteristics of the preform,the molding parameters design and process tests were performed.Equal-section preforms were prepared using advanced pultrusion process(ADP),and the preforms were twisted and filled into a spiral groove and vacuum-cured to prepare the related products.Studies have shown that the use of ADP has assitted the formation of equal-section spiral structure products with high degree of automation,compactness,and improved the appearance quality.
