The world's first fully automatic grinding wheel replacement system is online
Recently, the automatic grinding wheel online replacement system was successfully installed and debugged in Fujian Sangang Shuguang Co., Ltd. This system fills the gap in the use of medium and large-sized wheel saws, which is difficult to replace the saw blade automatically. It belongs to the world's first metallurgical equipment industry.
It is understood that Sangang Group has decided to use a large-scale grinding wheel to cut the bar to improve the bar specifications and quality in response to the problem that the cutting machine has a closed bar. The grinding wheel used in large-scale grinding wheel saws has a large weight and diameter (single piece 50kg, diameter 1250mm), high frequency of use, easy to wear and need to be replaced frequently. At present, domestic and foreign large and medium-sized grinding wheel pieces are manually replaced manually, at least Two workers can complete the replacement for more than half an hour, and the working conditions at the cutting site are poor, the replacement efficiency is low, the labor cost is high, and there are potential safety hazards.
Based on the above problems, in 2018, Sansteel Group and Sanming College rely on the Shuguang College jointly established by the two parties to jointly develop an automatic online replacement system for grinding wheel. The research and development personnel adopt machine vision technology and adaptive control algorithm to solve the problem of positioning accuracy of the grinding wheel and the spindle, so that the positioning accuracy can reach 20 microns. The system uses four-axis and six-axis robots for large-scale grinding wheel replacement, gasket and flange disassembly, shaft nut removal and fastening, and its visual aid system and central control system can move better. control.
According to reports, when it is necessary to replace, the operator only needs one button to start, and the whole process saw blade can be replaced within 8 minutes. According to the person in charge of the company, the equipment can replace a number of artificial high-risk operations, and generate annual benefits of more than 5 million yuan. Once the equipment is on the line, it can reach the standard and be promoted in mass production throughout the country.
