攀枝花矿山公司兰尖铁矿目前使用的20吨级TEXER33-07型自卸汽车,是由中英合资的内蒙古二机总厂生产的。其A型架球关节为进口部件,我国尚无一厂家生产。由于进口件价高且难以证保供应,生产中常因其短缺而使车辆不能投入使用。A型架球关节要求精度高、硬度大、耐磨性好,加工要求难度大,球形件及球碗热处理后的变形量要求严格,误差不得超过0.2毫米。试制管组大胆创新,利用电铲废轴为原料加工球关节。在热处理时,采
The 20-ton TEXER33-07 dump truck currently used by Panzhihua Mining Company Lanjian Iron Mine is produced by Sino-British joint venture Inner Mongolia Second Machinery Plant. The A-type ball and socket joints for the import of parts, there is no one manufacturer in China. Due to the high price of imported materials and the difficulty of securing the supply, vehicles can not be put into operation in production due to their shortage. A-type ball-joint requirements of high precision, hardness, wear resistance, processing requirements of the large ball and ball bowl after the heat treatment of the deformation required strict, the error shall not exceed 0.2 mm. Trial tube group bold innovation, the use of power shovel waste shaft as raw material processing ball joints. In heat treatment, mining
