Copper pipe blank sampling method and device for horizontal continuous casting process

The invention relates to the technical field of precision copper pipe detection, in particular to a copper pipe blank sampling method and device for a horizontal continuous casting process, and the method comprises the following steps: equipment erection: assembling a horizontal continuous casting production line, and arranging a cutting frame and a saw blade beside the horizontal continuous casting production line; process data recording: starting a horizontal continuous casting production line, keeping the copper pipe blank to move at a fixed speed v, recording each process parameter and a corresponding time point, and forming a database; a cutting frame is moved to enable the cutting frame and the copper pipe blank to move synchronously, the time point when the cutting frame just starts to move is recorded as a sample block time point T, and then a saw blade is used for cutting out a sample block; and sample block data matching: a plurality of sample blocks are manufactured, and according to the sample blo
