The operator must have a full understanding of the metal band sawing machine, and be able to deal with the small problems of the sawing machine in a timely and effective manner, skilled operation and protection, the operator's talent is the accumulation of daily operations. The metal band sawing machine is a hydraulic circuit composed of pumps, valves, cylinders, tanks, pipelines and other auxiliary parts through a hydraulic transmission system. The lifting of the saw beam and the clamping of the workpiece are completed under electrical control. Through the speed control valve, the stepless speed regulation of the feed speed can be implemented to meet the needs of sawing workpieces of different materials. The electrical control system consists of a control loop composed of an electrical box, a control box, a junction box, a travel switch, an electromagnet, etc., used to control the rotation of the band saw blade, the lifting of the saw beam, the clamping of the workpiece, etc., to make it follow a certain working procedure Sawing equipment to realize normal cutting cycle. How to operate it should be reflected in what aspects? Be able to understand parts drawings, simplified assembly drawings, and make general parts drawings. It can calculate the data consumption (total) amount and loss amount of single piece or batch cutting. It can perform the process documents correctly when cutting the metal band saw, and put forward suggestions for improvement, so as to be reasonable and save the cutting. It can paint the color according to the appearance of the data, and accurately point out the trademark of the data; it can correctly operate and adjust the commonly used metal band sawing machine, and can protect and maintain it. It can correctly load and unload band saw blades and saw blades, and sharpen saw blades and saw blades with blunt edges. It can install and adjust various special fixtures, and grasp the methods of using accessories for positioning, measuring and multi-piece clamping. It can correctly use and protect the commonly used measuring tools. It can take care of multiple devices and improve the active feeding mechanism; it can analyze and avoid defective products (saw face straightness, length scale, etc.) during cutting. Can distinguish the types of commonly used metal materials based on sparks. It can analyze and distinguish the cause of equipment failure, and can help machine and electric repair personnel to eliminate the problem. Be able to perform the basic operations of fitter, bind and lift the original materials. Able to guide metal band sawing machine cutting apprentices and trainees in practical operations. The above is the ability that the operator should master in using the metal band saw for everyone, so that the operation is more relevant.
