联合收割机的切割刀片是 用铆接方法固定在刀架上的。 如果动刀片或定刀片发生松 动,应该检查刀架总成有无卡 滞或碰撞现象,切忌盲目将刀 片焊死在刀架上。因为动刀架 是薄长杆件,多点焊接后因局 部受热,一但冷却,很容易产生 翘曲变形,刀架运动时出现阻滞、上下刀片相互干涉现象,进一步加剧 Cutting blades for combine harvesters are fixed to the tool holder by riveting. If the movable blade or fixed blade loosening, you should check whether the tool holder assembly stagnation or collision phenomenon, should not blindly welded to the blade on the knife holder. Because the moving knife holder is a thin long rod, due to local heating after multi-point welding, once cooled, it is easy to produce warping deformation, blockage occurs when the knife holder moves, and the upper and lower blades interfere with each other further
