Embodiment Construction

[0010] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0011] The method for on-line flaw detection and grinding of metal long products provided by the embodiments of the present invention has the following specific steps:

[0012] 1) Mark the incoming metal long products one by one. The specific method used for marking is to attach an RFID tag or a two-dimensional code tag to the end of the metal long material, and the attachment method is magnetic adsorption, so as to facilitate installation and removal.

[0013] 2) Identify and measure the diameter of metal long products one by one. According to the attached label, the corresponding identification device is an RFID reader-writer or a two-dimensional code identifier for identification, and the existing caliper is used for measuring the diameter.

[0014] 3) Flaw detection of metal long products one by one. The flaw detection method can be infrared, magnetic flux ...

Abstract

The invention discloses a method for online testing and grinding of a long metal material. The method comprises the following steps: marking, recognizing, calibrating and testing the long metal material; conveying the long metal material which meets the requirements and cannot be ground to a sorting station; conveying the long metal material which has defects and can be ground to a grinding station for grinding; carrying out secondary recognition and testing on the ground long metal material; conveying the long metal material subjected to grinding and secondary testing to the sorting station.An online testing and grinding system for the long metal strip is provided with a testing input roller table, a testing output roller table and a testing device, wherein a first recognition device anda diameter measuring instrument are arranged between the testing output roller table and the testing device; a grinding input roller table is arranged beside the testing output roller table; a grinding output roller table is arranged beside the testing input roller table; a second recognition device and a grinding device are arranged between the grinding input roller table and the grinding outputroller table. The system is also provided with a control processor. According to the method, testing and grinding of the long metal material are integrated in the primary production process; the testing and grinding system can test and grind the long metal material.

Description

technical field [0001] The invention relates to metal flaw detection and grinding technology, in particular to a method and system for online flaw detection and grinding of metal rods, pipes, wires or profiles. Background technique [0002] In the production of metal long products (rods, pipes, wires or profiles), due to the unavoidable air bubbles and other surface defects on the surface of the continuous casting slab, the continuous casting air bubbles will be stretched during rolling and extrusion. It is a long and thin surface crack, and other surface defects are also stretched, which will cause the surface of the long product to be unacceptable. For these unqualified metal long products, surface grinding can be used to make them qualified. [0003] The existing flaw detection line for metal long products only has a flaw detection input roller table, a flaw detection output roller table and a flaw detection device, and the flaw detection device is arranged between the f...
