摘　　要：目前常用的绞龙叶片胎具成型法,由于需要购买设备和专用模具,投资较大,不适用于非标准绞龙叶片的小批量生产。为了解决这一问题,研制了新型绞龙叶片拉伸机,该机包括机架装置、传动装置和拉伸装置,传动装置采用分路传动定轴轮系驱动,拉伸装置利用复式螺旋机构的原理将绞龙叶片坯料拉制成型。通过更换不同直径的套管,可以拉制不同尺寸的绞龙叶片,实现一机多用。该机便于制造和移动,适用性强,重量轻,体积小,具备一定的市场推广前景。文章还给出了拉伸绞龙叶片展开修正公式,通过拉制外径150 mm的绞龙叶片试验验证,拉制后达到设计要求。The mould forming method commonly used at present is not suitable for the small batch production of non-standard spiral blades due to the large investment in purchasing equipment.In order to solve this problem,a combined spiral blade stretcher is developed,which consists of a frame part,a transmission part and a stretching part.In the transmission part,three single spiral blade stretchers are driven by a divided drive fixed shaft gear train,and the stretching part is drawn and formed by the principle of a compound spiral mechanism.The machine is multi-purpose as it can process the spiral blades with different specifications by changing the casing with different diameters.It is small in size,light in weight,easy in mobility,wide in application,unsophisticated in manufacturing,and has potential market to a certain extent.The paper also gives the expansion correction formula of the stretch spiral blade which is testified with an experiment using the spiral blade with 150 mm outside diameter.
