Finishing and grinding device for nodular cast iron pipe

Abstract

The invention relates to the technical field of nodular cast iron pipe production, and discloses a finishing and grinding device for a nodular cast iron pipe. The finishing and grinding device comprises a processing table, wherein a fixing frame is fixedly installed at the top of the processing table, and the right side of the fixing frame is connected with a grinding head used for grinding through a driving motor. According to the device, during grinding, a part of chippings are leaked into a collecting box through a leakage net to be collected and ground, then chippings in a pipe are poured on the leakage net, a part of chippings are accumulated on the leakage net and are not leaked, at the moment, a suction fan is controlled to operate, air suction is carried out through an extension pipe, and when the suction fan carries out air suction, the chippings remaining on the leakage net can be sucked into the extension pipe, and a partition plate intercepts the chippings; and when the suction fan is disconnected, the chippings can slide downwards along the surface of the partition plate and enter the collecting box through a guide groove and a leakage groove to be collected again, therefore, the chippings generated during grinding and the chippings accumulated in the pipe after grinding can be conveniently cleaned, and the overall processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ductile iron pipe production, in particular to a finishing and grinding device for ductile iron pipes. Background technique [0002] Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of centrifugal ductile iron machine after casting molten iron above No. 18 with the addition of nodularizer, referred to as ball pipe, ductile iron pipe and ductile cast pipe. It is mainly used for the transportation of tap water. It is an ideal material for tap water pipes. During the processing of ductile iron pipes, the cast iron pipes need to be polished, and a large amount of debris will be generated during grinding. The debris is accumulated on the processing table and needs to be polished. Manual cleaning after contact will lead to the problem of lower overall processing efficiency. [0003] For this reason, we propose a finishing grinding device for ductile iron pipes. Contents of the inve...
