Machining production method special for nodular cast iron pipe finishing unit

Abstract

The invention relates to a machining production method special for a nodular cast iron pipe finishing unit, and belongs to the field of pipe production equipment. In the prior art, independent operation needs to be carried out, and a working period is long. The machining production method special for the nodular cast iron pipe finishing unit comprises the following steps that a to-be-chamfered pipe is placed on a chamfering station for being chamfered through a travelling crane, and the to-be-chamfered pipe is erected on a chamfering riding wheel assembly, so that one end of the to-be-chamfered pipe is in contact with a chamfering grinding wheel; the chamfered pipe is placed on an internal grinding station for inner grinding through the travelling crane, the to-be-ground pipe is erected onan inner grinding driving riding wheel and an inner grinding driven riding wheel, and one end of the to-be-ground pipe is in contact with a blocking wheel body; and the internally-ground pipe is placed on a roller coating station for roller coating through the travelling crane, the to-be-roller-coated pipe is erected on a roller coating riding wheel assembly, one end of the to-be-roller-coated pipe is erected on a roller coating positioning boss, and roller coating is conducted on the to-be-roller-coated pipe. According to the method, the working efficiency is improved, and assembly among allpipes is facilitated.

Description

technical field [0001] The invention relates to a processing and production method specially used for a nodular cast iron pipe finishing unit, belonging to the field of pipe fitting production equipment. Background technique [0002] The ductile cast iron pipe will go through a series of treatments during processing and production, such as chamfering, internal grinding and rolling paint, in order to prolong its service life and improve sealing performance. At present, there is no equipment that can chamfer, The integrated operation of internal grinding and painting is realized. In the prior art, chamfering, internal grinding and painting need to be operated independently, the working cycle is long, the efficiency is low, and it is difficult to realize continuous production in the process of independent operation. Each process is operated independently, and the desired effect cannot be achieved, such as irregular chamfering, uneven internal grinding, uneven rolling paint, etc...

AI Technical Summary

Problems solved by technology

The above comparison file can only realize the function of chamfering, not the simultaneous realization of functions such as internal grinding and rolling paint, and the functional efficiency is low
