上海马铁厂生产的中小型铸件过去都是采用六角清理滚筒进行清理,生产率低,每班仅5～6吨,劳动条件差。在党的“九大”团结、胜利路线指引下,该厂三结合设计小组群策群力,制成一种简易连续清理滚筒,结构如图所示。需清理的铸件连续地由鳞板输送器沿斜槽装进滚筒,由于这种滚筒不用星铁,仅依靠铸件间的摩擦和撞击来进行铸件的清理,故在后四节采用倒装叶片和挡圈。滚筒总长6米,使铸件在滚筒内保持10～15分钟清理时间。另外,在操作时采用间断启动,使工作面上始终积聚一定数量的铸件,保证了铸件之间充分接触,提高清理质量。经
Small and medium-sized castings produced by Shanghai Ma Tiechang used to be cleaned by hexagonal cleaning rollers with low productivity, only 5 ~ 6 tons per class, and poor working conditions. Under the guidance of the party’s “Ninth” solidarity and victory line, the three-in-one design team of the plant worked together to form a simple continuous clean-up drum. The structure is as shown in the figure. The castings to be cleaned are continuously fed from the slat conveyor along the chute into the drum. Since this drum does not use the stellate iron and only relies on the friction and impact between the castings for the cleaning of the castings, Ring. Roller total length of 6 meters, the casting in the drum to maintain 10 to 15 minutes to clean up time. In addition, the use of intermittent operation in the operation, so that the face always accumulate a certain number of castings to ensure full contact between the castings to improve the quality of clean-up. through
