Method for achieving identification and recognition through metal cutting end surface microscopic geometrical shape

Abstract

The invention discloses a method for achieving identification and recognition through a metal cutting end surface micro geometrical shape, which comprises the following steps of: cutting a metal pipeblank into blanks section by section, and performing micro geometrical shape scanning and algorithm feature extraction on the end surface of the blank through scanning acquisition equipment; marking the feature data obtained by scanning in the same batch, matching the feature data with the corresponding data, and uploading the feature data to a corresponding system platform for storage through anindustrial network. The production data management system is used for processing the microscopic geometrical shape feature identification of each batch of blanks, the production and processing processdata, the furnace number, the batch number, the serial number and other information so as to facilitate subsequent information tracing and management of the same batch. The steel pipe or steel bar one-by-one tracking system is established, the corresponding relation between each technological process data of the steel pipe or steel bar production process and the specific steel pipe or steel bar can be achieved, and the quality control precision and reliability of the steel pipe or steel bar are greatly improved.

Description

technical field [0001] The invention relates to a metal identification and identification method, in particular to a method for realizing identification and identification through the micro-geometric shape of the metal cutting end face. Background technique [0002] The production of steel pipe or steel rod is a discrete and discontinuous processing mode. During the production process, unqualified products go offline and rework is inevitable. The complex production process of steel pipe or steel rod determines that it cannot be processed in the same advanced way as ordinary products. First out for tracking, the tracking of steel pipes or steel rods must be positioned on each specific one to achieve accurate tracking. The tracked elements include information such as furnace number, batch number, and corresponding processing data. Each furnace number and batch number will correspond to a batch of steel pipes or steel rods. After many days, it is difficult to trace the specifi...

Problems solved by technology

[0004] In the process of steel pipe or steel rod production, the processing site environment is harsh, there are interference factors such as oil pollution, high temperature, high pressure, water mist, noise, etc., and the changes and fluctuations in lighting conditions are large, and the background area is relatively complicated. The positioning and extraction of the method cause a certain degree of interference, so the implementation cost is relatively high, and the effect is not ideal

For manual tracking, due to the individual differences of each person, it is difficult to ensure accuracy. Therefore, the identification technology of steel pipes or steel rods has always been a difficult point to realize the tracking of steel pipes or steel rods.
