How to install molybdenum wire in wire cutting?

If the molybdenum wire is installed too loosely, the molybdenum wire will vibrate violently, which will not only cause wire breakage but also directly affect the surface roughness of the workpiece due to vibration of the molybdenum wire. However, the molybdenum wire should not be installed too tightly. If it is too tight, the internal stress will increase, which will also cause the wire to break. Therefore, the molybdenum wire should be properly tightened during the cutting process. The newly installed molybdenum wire should be tightened first and then processed. Do not use too much force when tightening the wire. After a period of processing, the molybdenum wire becomes loose due to its own stretching. When the elongation is large, the vibration of the molybdenum wire will be aggravated or the molybdenum wire will overlap on the wire storage drum. Make the wire run unstable and cause wire breakage. The tightness of the molybdenum wire should be checked frequently, and if there is slack, it should be tightened in time.

Wire cut molybdenum wire installation. The molybdenum wire should be wound on the wire storage drum according to the specified direction, and the two ends should be fixed at the same time. When winding the wire, generally leave 10mm at both ends of the wire storage drum, the middle is full and does not overlap, and the width is not less than half of the length of the wire storage drum, so as to avoid frequent motor commutation and accelerate damage to the machine parts, and prevent molybdenum wire from frequently participating in cutting. And broken wire.

There is a wire stopper at the lead out of the molybdenum wire on the wire cutting machine. The stopper rod is a guide column made of two rubies. The stopper rod does not roll like a guide wheel, but they directly contact the molybdenum wire for sliding friction. Therefore, the wear is very fast, and a deep groove will be formed where the cylinder contacts the molybdenum wire soon after use. It must be checked and turned over and replaced in time, otherwise, there will be overlapping and broken wires.
