DN400-DN1200 centrifugal nodular cast iron pipe socket ovality detection and correction system

Abstract

The invention discloses a DN400-DN1200 centrifugal nodular cast iron pipe socket ovality detection and correction system. The system comprises an upper computer, a processor, a measurement sensor and a touch screen operation panel. The upper computer is connected with the processor and is used for sending an instruction; the touch screen operation panel is connected with the processor and is used for inputting control detection and correction; the measuring sensor is connected with the processor through the analog quantity signal processing unit and is used for testing on site to obtain a stable numerical value; and the processor is connected with the rounding control mechanical hydraulic equipment and is used for obtaining a long axis and a short axis of the ovality of the cast iron pipe by editing a data processing program block according to stable numerical values obtained through field testing, then controlling the cast iron pipe to rotate to the position of the long axis and controlling the rounding equipment to conduct automatic rounding. According to the detection and correction system, automatic roundness correction of the centrifugal nodular cast iron pipe socket is achieved, efficient and accurate measurement and control are achieved, repeated detection and verification can be achieved, the labor intensity of workers is greatly reduced, and the quality of a cast pipe is guaranteed.

Description

technical field [0001] The invention relates to a DN400-DN1200 centrifugal ductile iron pipe socket ellipticity detection and correction system. Background technique [0002] The ovality of the socket of the centrifugal ductile iron pipe is an important index to measure the quality of the pipe. If the ovality is greater than the specified value, it needs to be corrected. [0003] At present, the calibration is mainly done manually after the on-site inspection of the standard round mold used by post workers. A cast iron pipe usually needs multiple inspections and calibrations, and the workload is heavy, which seriously affects the production rhythm. [0004] Therefore, there is an urgent need to provide a DN400-DN1200 centrifugal ductile iron pipe socket ellipticity detection and correction system to solve the above technical problems. Contents of the invention [0005] The purpose of the present invention is to provide a DN400-DN1200 centrifugal ductile iron pipe socket e...
