以250 t桥式天车为例,介绍了小车架的装焊制造新工艺方法,在保证产品质量要求的前提下,用分部件组装焊接后整体配割试装的工艺方案,替代整体装配焊接的传统制作工艺,解决了传统工艺制造中存在的安装车轮轴承箱4组弯板壁厚减薄、几何公差超差等影响产品质量的问题.%The article introduces a new method for manufacturing the small carriage of 250 t bridge crane. The traditional method is assembling and welding the carriage as a whole, otherwise the new method is cutting and test assembling totally of the carriage after welding the parts. Therefore it can solve the problems of reduction for bent plate wall thickness , overrun the tolerance for the wheel (8 pieces).
