1.一般加工方法目前国内履带起重机生产厂家吊臂腹管相贯线端面加工方法一般有2种:一是使用铣床铣削加工。铣削前将腹管固定在铣床工作台上,选择与吊臂主弦管直径相同的刀盘。铣削时刀盘做旋转运动,从而将腹管端面铣削成相贯线形状。二是使用相贯线数控切割机切割加工。该种切割机进行火焰切割时,腹管的切割区域会失去原有强度,因此履带起重机生产厂家—般不采用此种加工方法。
1. General Processing Method At present, there are two kinds of processing methods for the crane boom belly pipe intersecting line in the domestic crawler cranes: First, the milling process is used. Before milling, fix the abdominal tube on the milling table and select the cutterhead with the same diameter as the main chord of the boom. Milling the cutter to do rotational movement, which will be the end of the abdominal tube into a cross-line shape. The second is the use of intersecting CNC cutting machine cutting. This kind of cutting machine for flame cutting, abdominal pipe cutting area will lose its original strength, so crawler crane manufacturer - generally do not use this processing method.
