为了提高汽车甩油管弯管质量,北京汽车设备修造厂设计制造了钢珠同步弯管器,经使用弯管质量有明显提高,管子薄壁变形量小,两侧膨胀小于0.2毫米,弯度收缩变形小于0.5毫米,外表光滑、美观,全部满足零件精度要求;而且使用方便,弯管时不需加热、不用灌铅,降低了成本。钢珠同步弯管器的结构如图所示。定位轮、支承轮分别固定在平板上,定位轮与滚轮相互啮合,联板上的螺杆底部,装有和加工管子内径相等径的钢珠,并通过圆螺母将钢珠中心调
In order to improve the quality of elbow pipe of automobile rejection pipe, Beijing auto equipment repair factory designed and manufactured the steel pipe bending pipe, the quality of elbow pipe improved obviously, the deformation of pipe thin wall is small, the expansion on both sides is less than 0.2 mm, the bending shrinkage deformation is less than 0.5 mm, the appearance of smooth, beautiful, all to meet the accuracy requirements of parts; and easy to use, no need to heat pipe when bent, do not lead injection, reducing costs. The structure of the steel pipe bender is shown in the figure. The positioning wheel and the supporting wheel are respectively fixed on the flat plate, the positioning wheel and the wheel are meshed with each other, the bottom of the screw rod on the connecting plate is provided with a steel ball with the same diameter as the inner diameter of the pipe and round the center of the steel ball
