Molybdenum wire mounting bracket
The existing wire cutting is to use molybdenum wire as a long electrode and pulse corrosion discharge between the workpiece to process the workpiece, so it is necessary to ensure the existence of molybdenum wire electrode on the machine tool and keep it in good condition.
When the new machine tool or the wire is broken, it is necessary to install the new wire neatly on the molybdenum wire tray of the machine tool; The new wire installation is to place the molybdenum wire disc equipped with new wire on the wire frame fixed on the fuselage. The molybdenum wire disc is installed on the mounting shaft of the wire disc, and is fixed on a certain position on the shaft by the elastic force after compression of the clamping spring and the clamping force of the clamping nut.
After the molybdenum wire disk is subjected to the axial elastic force, when the molybdenum wire disk is installed and rotated, the friction between the molybdenum wire disk and the end face of the clamping nut and the end face of the spring ensures that the molybdenum wire cloth always has a certain tension around the molybdenum wire disk, and the molybdenum wire is kept neat and consistent on the molybdenum wire disk.
Because the axial diameter of the inner hole of the positioning molybdenum wire disc on the existing wire cut wire disc mounting shaft is the same as the axial diameter of the positioning clamping spring inner diameter, which limits the choice of spring. When installing molybdenum wire, even if the length direction is compressed in the end, the clamping force of the spring is not big; The friction between molybdenum wire disc and spring end face is also uncertain, resulting in uncertain tension of molybdenum wire on molybdenum wire disc.
The axial diameter of the inner diameter of the positioning clamping spring on the mounting shaft of the molybdenum wire mounting bracket is larger than the axial diameter of the inner hole of the positioning molybdenum wire disc, which is conducive to choosing the appropriate clamping spring according to the tension requirements of the molybdenum wire layout in the molybdenum wire disc, so as to make the molybdenum wire stable tension on the molybdenum wire disc.
