Control method and device of grinding machine

Abstract

The invention discloses a control method and device for a grinding machine. The control method comprises the following steps that 1, the thickness of a workpiece is set, and the grinding machine is started; 2, the polishing mechanism returns to the zero position, and the initial value of the measuring mechanism is set; 3, the measuring mechanism measures the grinding mechanism to obtain the abrasion loss of the grinding mechanism and transmits the abrasion loss to the PLC; 4, the PLC controls the grinding mechanism to carry out abrasion loss compensation, so that the subsequent grinding is more accurate; 5, the cutting depth of the grinding mechanism and the pressing amount of the pressing mechanism are input, and the grinding mechanism, the conveying mechanism and the pressing mechanism are started; and 6, a to-be-polished workpiece is put in, and the polishing machine conveys and polishes the workpiece. The method is adopted for polishing burrs, slag and oxide skin on the surface of the workpiece, polishing can be automatically carried out, a grinding tool is compensated, polishing is more accurate, meanwhile, manual operation is not needed in the polishing process, a large amount of manpower can be saved, the polishing efficiency is improved, and the production cost of an enterprise is reduced.

Description

technical field [0001] The invention relates to the technical field of steel plate surface grinding, in particular to a control method and device for a grinding machine. Background technique [0002] At present, flame, plasma cutting and other technologies are generally used in the steel structure industry to cut and blank the steel plate, but during the cutting and blanking process, slag, burrs and oxide scale will remain on the surface of the steel plate. The oxide scale removal method is generally manual removal, which is manually removed by using a grinding wheel grinder, but manual grinding has poor quality, low precision and high labor intensity, which cannot be adapted to the production mode of mass production; at the same time, manual grinding will generate a lot of dust. Particles and dust particles floating in the air will pollute the environment or be inhaled by the human body, which will seriously affect the health of workers. In the era of increasing awareness o...

Problems solved by technology

[0002] At present, technologies such as flame cutting and plasma cutting are commonly used in the steel structure industry to cut and blank steel plates. The oxide scale removal method is generally manual removal, which is manually removed by using a grinding wheel grinder, but the quality of manual grinding is poor, the precision is low, and the labor intensity is high, which cannot adapt to the production mode of large-scale production; at the same time, manual grinding will generate a lot of dust Particles and dust particles floating into the air will pollute the environment or be inhaled by the human body and seriously affect the health of workers. In the period of increasing awareness of environmental protection, there is an urgent need for a grinding method and device that can quickly polish the surface of the steel plate and is more environmentally friendly. It can quickly remove slag, burrs or scale on the surface of the steel plate, and can significantly improve the grinding quality and grinding accuracy, reduce labor intensity, and save production costs
