Problems solved by technology

[0002] Because cold heading steel has very high requirements on the surface quality of steel, in order to check the surface quality of this type of steel wire rod, the method of pickling the coil sample is usually used for testing, that is, the wire rod sample is directly pickled to make the surface of the sample oxidized After the iron sheet comes off, whether there are defects on the surface of the sample is manually observed. The above method has the following problems: (1) the pickling process will not only pollute the environment, but the residual pickling solution on the surface of the sample will affect human health when judged by the naked eye. It will also cause a great impact; (2) No matter how the standard is limited, manual detection will inevitably have a certain degree of subjectivity, and the rate of missed detection and false detection will be greater; Labels are attached to the samples for recording, which increases the complexity and safety issues of manual operations
So far, the above operations are all done manually, and only one sample can be tested at a time, which is time-consuming, labor-intensive, inefficient, and has potential safety hazards

Abstract

The invention relates to an online steel wire rod cold heading test recording method and system, aiming at solving the problems that when an existing steel wire rod meter is detected, manual detection is adopted, so that the production efficiency is low, the safety is poor, and labor and force are consumed. The system comprises a straightening system, a conveying system, a first clamping device, a cutting system, a cold header, a second clamping device and a meter detection device; a steel wire rod cut from a production line is straightened, conveyed, clamped, cut and treated by cold heading and meter detection, so that online steel wire rod cold heading test recording can be realized. The method can completely replace the manual detection, and is simple in technology, safe, reliable, high in efficiency, time-saving, labor-saving and environmentally friendly.
