Description

technical field [0001] The invention relates to a headless bearing type centrifugal main engine of a centrifugal pipe casting machine, which belongs to the field of mechanical equipment. Background technique [0002] The centrifugal main engine of the centrifugal pipe casting machine is used in the processing of ductile iron pipes. During the processing of ductile iron pipes, molten iron needs to be poured into the pipe mold. The centrifugal main engine drives the pipe mold to rotate at a high speed, so that the molten iron is formed in the pipe mold and cooled. Casting into pipe fittings, before pouring molten iron into the pipe mold, it is necessary to block the socket end of the pipe mold with a sand core to prevent the molten iron used in pouring from flowing out, and then pour molten iron into the pipe mold from the socket end of the pipe mold to process the pipe. For pipe fittings with a diameter of less than 1200mm, the socket end of the pipe mold is supported by bear...

[0002] The centrifugal main engine of the centrifugal pipe casting machine is used in the processing of ductile iron pipes. During the processing of ductile iron pipes, molten iron needs to be poured into the pipe mold. The centrifugal main engine drives the pipe mold to rotate at a high speed, so that the molten iron is formed in the pipe mold and cooled. Casting into pipe fittings, before pouring molten iron into the pipe mold, it is necessary to block the socket end of the pipe mold with a sand core to prevent the molten iron used in pouring from flowing out, and then pour molten iron into the pipe mold from the socket end of the pipe mold to process the pipe. For pipe fittings with a diameter of less than 1200mm, the socket end of the pipe mold is supported by bearings, and pipe fittings with a diameter of less than 1200mm cannot be processed

[0003] In view of this, a centrifuge dedicated to pouring ductile iron pipes is disclosed in the patent document with the announcement number 201621484921.0. The centrifuge in the above reference document is suitable for processing pipe fittings with a pipe diameter of 1200mm or less, and cannot process pipe fittings with a pipe diameter of 1200mm or more. pipe fittings
