搅龙轴在工农业生产中应用广泛。其结构大都为组合构件,即绞龙叶片和芯轴杆联结为一体。目前搅龙叶片制作方法有钢板挤压成形和用专门的机器轧制成形。挤压成形法生产效率低,并且对叶片材料要求高,即对材料厚度、拉延性能要求较高。搅龙叶片轧制机购置费用高,一般单位购买困难,而且对叶片材料钢板要求也高。 Squibbling shaft widely used in industrial and agricultural production. Most of its structure for the combination of components, namely, the blade and the spindle screw shaft as a whole. At present, the production of auger leaves are produced by sheet extrusion and rolling by a special machine. The extrusion forming method has the advantages of low production efficiency, high requirements on the material of the blade, that is, the requirements on the material thickness and drawing performance are higher. Auger blade rolling machine purchase costs are high, the general unit to buy difficult, but also on the leaf material steel requirements are high.
