Steel material texture detection method and device utilizing same

Abstract

The invention discloses a steel material texture detection method and a device utilizing same, and is used for detecting a steel material texture of a workpiece during processing in a numerical control angle steel typing punching shearing production line / a numerical control plate material punching typing machine. The detection method includes the following steps: (1) arranging a pressure detection device on the numerical control angle steel typing punching shearing production line / the numerical control plate material punching typing machine, and employing the pressure detection device to acquire a pressure numerical value when the workpiece to be detected is punched; (2) building a standard punching pressure database of angle steel / plate materials with various textures in a microcomputer, comparing and judging the database with the acquired pressure numerical value, and displaying the judged result through a human-computer interaction interface of the microcomputer; and (3) when the judged result displayed in the human-machine interaction interface is inconsistent with the texture of the workpiece in a processing batch, starting an alarm device for alarm by the microcomputer, and reminding an operator to take out the problem workpiece. The detection method can detecting the texture of each angle steel or each plate material used in a production process, and is accurate and quick.

Description

technical field [0001] The invention relates to a method for detecting the steel material, in particular to a method for detecting the steel material of a workpiece in a numerically controlled angle steel typing punching and shearing production line / a numerically controlled plate punching typewriter. The invention also relates to equipment utilizing the steel material detection method. Background technique [0002] Angle steel and plates are necessary raw materials for iron tower processing. The commonly used angle steel or plate materials for iron tower processing are generally Q235, Q345, Q420, and Q460. In the process of processing and bundling in steel mills and in the actual processing of iron tower processing enterprises, sometimes one or several steels of a certain material are mixed into steels of another material. Iron tower processing enterprises mistakenly process and use Q235 angle steel or plate as Q345, Q420 or Q460 due to mixing materials in the processing pr...

Problems solved by technology

In the process of production and processing, because these two kinds of equipment are in the process of punching angle steel or plate, the workpiece will make a certain sound. The sound of Q345, Q420 and Q460 angle steel is clear and loud, and the sound of Q235 angle steel is low and soft. Experienced machine tool operators can roughly judge the material of the workpiece to be processed by the sound produced during punching or cutting. The sound is low and soft is Q235, but the sound of the three materials Q345, Q420, and Q460 is relatively crisp and bright. Difficult to distinguish by sound alone

This identification method has a lot to do with the experience of the employees, the level of responsibility, and the quality of the mental state, so it cannot be popularized and applied.
