Finishing platform of online composite finishing robot

Abstract

The invention discloses a finishing platform of an online composite finishing robot. According to the platform, robots of different finishing methods are combined and applied to a conveying line or arolling line of a rolled piece and a finished piece, defects appearing on the surfaces of the rolled piece and the finished piece can be found in real time, the found surface defects are rapidly finished and removed online, and the process progress is not influenced. Rapid finishing can be achieved on a finishing line; and new surface defects can be removed while rolling is carried out through a rolling mill, and the rolled material quality is improved. The method is applied to the iron and steel industry, the casting blank hot delivery efficiency can be improved, the yield of rolled materialsis increased, and particularly, the yield of rolled materials of continuous casting and rolling can be improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical finishing automation, in particular to an online robot finishing platform on a conveying line and a rolling line. Background technique [0002] Rolling processing requires qualified raw materials, that is, there must be no surface and internal defects, and surface finishing treatment is required, otherwise there will be defective and defective products. New defects will also appear in the rolling mill during the rolling process, which will affect the quality of the final product. For this reason, the patent application number is: 201910377287.2, the patent of "on-line robot finishing platform for rolling mill and extension line", which proposes a solution. But the implementation of this patent scheme also has the following problems: [0003] 1.

Problems solved by technology

[0003] 1. After finishing with a single arc finishing robot (including plasma finishing), local high temperature will be generated on the surface of the finished piece, which will affect the material of the rolled material. The local high temperature of the rolled piece on the rolling mill line will also affect the life of the roll. For some The surface roughness of the rolled material cannot meet the requirements after plasma cleaning, thus affecting the quality of the final product;

[0004] 2. Using a single flame cleaning robot finishing method will also generate local high temperature, which will affect the material of the rolled material and the life of the roll. The surface roughness of some rolled materials after flame cleaning cannot meet the process requirements;

[0005] 3. Using a single grinding wheel grinding robot finishing method, due to the limited grinding depth capability of the grinding wheel, it is extremely difficult to implement the grinding wheel

The reasons are as follows: Pressing down the grinding wheel with a large pressure can increase the grinding depth, but it will affect the running of the rolled piece on the track and there is also the danger of blasting the grinding wheel, which is very unsafe; Grinding the surface far can avoid high-temperature rolling parts from burning the grinding wheel bearings. For example, the temperature of hot-rolled steel plates is usually >1100 °C, but the large grinding wheel is limited by the installation space and the number of installations. When parallel multi-point defects appear on the surface, they cannot be processed at the same time. It is difficult to meet the process and speed requirements; when grinding with a small grinding wheel, there are pressure requirements, high speed requirements, high temperature requirements, and long-term work requirements. Bearings suitable for this working condition At present, it is not possible to realize the industrial
