Online flaw detection process of pipeline forming and machining process

Abstract

The invention discloses an online flaw detection process of a pipeline forming and machining process, which comprises the following steps of: additionally arranging a high-temperature resisting flaw detection head of a through vortex flaw detector and a counting device behind a discharging port of forming and machining equipment, and spacing a distance A between the high-temperature resisting flaw detection head and the counting device; additionally arranging a drive device and an alarm device in the through vortex flaw detector, connecting the control end of a detection device with the drivedevice and the alarm device, connecting the drive device with the counting device, and connecting the high-temperature flaw detection head and a length measuring device with the detection device; passing a pipeline from the discharging port through the high-temperature resisting flaw detection head first, carrying out online detection by the high-temperature resisting flaw detection head, once flaw points are founded, conveying detection signals of the flaw points to the detection device in time through the high-temperature resisting flaw detection head, processing the detection signals by the detection device, calculating a pipeline forwarding distance according to a distance signal transmitted from the length measuring device, when the distance is equal to the spaced distance A, drivingthe counting device by the drive device to carry out counting on the flaw points, giving an alarm in time and notifying operation personnel for processing.

Description

technical field [0001] The invention relates to a detection process, in particular to an online flaw detection detection process in the pipeline forming process. Background technique [0002] Pipelines in the prior art, such as the copper tube forming process, only process the copper tube. The size of the formed copper tube is controlled by the mold used in production. It is impossible to confirm whether the processed product is qualified or whether the surface is defective. . Generally, after the copper pipe is formed in the production process, the formed product is inspected by the next process to confirm whether the product is qualified, and the unqualified product is scrapped, and the cause of the unqualified product is analyzed and fed back to the superior. Because the whole process needs a certain amount of time for communication and confirmation, it is easy to cause batch failure of products with the same quality problem in the actual production process. In addition...
