北京211厂有色金属铸造车间,对砂型生产的铝合金大圈铸件,为了补缩在端面上设置了12个冒口。冒口经带锯机锯掉后还剩有残根,在冒口处又容易产生一些铸造缺陷,如缩松、缩孔、热裂、夹渣等。由于铸件要求较高,需将冒口残根铲平,经X光透视合格后,才能经时效处理,再送往机加工车间加工。铸造车间清理工部没有能加工直径在2米以上的立式大车床,冒口残很原来只能用人工剔铲锉平。为此设计制造了升降旋转移动托 Beijing 211 non-ferrous metal foundry foundry, the production of large-scale aluminum alloy ring casting, in order to complement the set in the face of 12 risers. Riser after sawing left with a residual root, riser and prone to some casting defects, such as shrinkage, shrinkage, thermal cracking, slag and so on. Due to the higher casting requirements, the risers need to shovel flat, X-ray perspective qualified to aging treatment, and then sent to machining shop processing. Casting workshop cleaning department did not have the ability to process more than 2 meters in diameter vertical lathe, riser residual original can only use manual pick shovel file level. To this end, the design and manufacture of lifting rotating mobile care
