Description

Device for preventing flow groove of centrifugal machine from shaking Technical Field The utility model relates to the technical field of pipe fitting manufacturing, in particular to a device for preventing a centrifuge from vibrating. Background Molten iron flows to a launder elbow through a launder and falls into a pipe die during centrifugal casting of the centrifugal spheroidal graphite cast iron pipe, and molten iron is continuously cast into the rotary moving pipe die through rotation of the pipe die and descending of a centrifugal machine, so that the centrifugal spheroidal graphite cast iron pipe is formed. The continuous flow of molten iron is small in production of the small-caliber ductile cast iron pipe, when molten iron is poured in, the whole launder is provided with a long and thin supporting structure which is not stable in the pipe die, shake is easy to generate, molten iron can be splashed in the middle of the launder into the pipe die to cause uneven molten iron distribution in the pipe die, and the forming of a pipe body is greatly affected. The existing general manual direct-current launder of pressing through the manual work with the steel pipe prevents the launder shake, because in the production pipe die lasts rotatory removal, the position that the manual work was pressed also need follow the removal of pipe die and can adjust correspondingly, and molten iron temperature is high, and personnel need push down the operation in relatively poor operational environment for a long time, and workman's intensity of labour is high also comparatively dangerous.
