　　The combined use of sawing machine and saw blade can effectively meet the sawing work of major companies on workpieces. Only by operating the sawing machine and saw blade in the correct way can the workpiece with high precision and meeting production conditions be sawed! In addition, do a good job The installation of the saw blade on the sawing machine is also very critical. If the installation of the saw blade is not in place, it will directly affect the sawing effect of the sawing machine on the workpiece, and it may even cause problems such as failure during the operation of the sawing machine. Therefore, when replacing the saw blade with a new saw blade, everyone must master the correct method. Then what is the specific method of replacing the saw blade? The following is the saw blade manufacturer to tell you!

　　When replacing the saw blade, first open the upper and lower guard doors, loosen the sliding plate fixing screw, turn the lifting hand wheel to lower the upper saw wheel, the saw blade is loose, take out the old saw blade, put the polished saw blade on the upper and lower saw wheel, pay attention to the sharp angle of the saw tooth The direction is down, do not turn up, and then turn the lifting hand wheel to raise the upper saw wheel and tighten the saw blade. Then turn the upper saw wheel by hand to see if all the saw teeth are exposed on the outer side of the saw wheel rim. If they are not exposed, adjust the upper saw wheel until the saw teeth expose the rim and move smoothly on the upper and lower saw wheel edges. Up to perpendicular to the work surface.

　　The saw blade tensioning device is divided into two types: spring and pressure thallium (heavy hammer). This machine is a spring device. The base tension should be determined according to the width, thickness, and speed of the saw blade. The saw blade is usually pressed by fingers, and the tension of the saw blade is determined according to the left and right curvature of the saw blade. In general, when the saw blade is pressed by hand, the curvature of the saw blade should be between 3.2 and 6.4 mm.

　　The width of the saw blade should be compatible with the width of the saw wheel's wheel surface, and should not exceed the wheel surface too wide.

　　The saw blade is clamped in the middle of the saw clip. The bottom of the serrated teeth should be in line with the outer edge of the saw clip. The saw blade should not be clamped too tightly. It should be able to slide in the middle of the saw clip. There should be gaps on both sides, the gap on each side is about 0.04~0.08 mm. The back of the saw blade is about 0.8 mm away from the pulley. If the saw blade is in contact with the pulley when idling, it means that the saw blade is back, or the pulley is forward, or the tension of the saw blade has disappeared. Adjust the upper saw wheel or pulley, or remove the saw blade. Check rolling and trimming.

　　The above is the correct way to replace the saw blade introduced by the editor. I hope it will be helpful to everyone after reading it! In fact, there are many types of saw blades. Therefore, when replacing the saw blade, you must first select the appropriate saw blade, and then Then follow the above method to replace the saw blade, so as to ensure the actual application effect of the saw blade in the later period, and also ensure the efficiency of the saw blade to cut the workpiece!
