Description

Technical Field

[0001] The utility model belongs to the technical field of wire cutting and relates to a wire cutting guide wire angle adjustment device. Background Art

[0002] The wire cutting machine realizes the cutting operation of the workpiece to be cut by the high-speed movement of the energized molybdenum wire. When working, the workpiece with cutting is fixed, and the molybdenum wire on the cutting head mechanism of the wire cutting device is close to the workpiece. The high-speed moving molybdenum wire realizes the cutting of the metal workpiece through the effect of electrocorrosion. However, in the existing wire cutting device, the molybdenum wire is usually arranged in the vertical direction, so that the incision is always arranged in the vertical direction. If you want to cut incisions of different angles on the workpiece, it is achieved by moving the molybdenum wire at an angle. When the molybdenum wire is vertical, the tangent points of the upper guide wheel, the lower guide wheel and the molybdenum wire are all on the horizontal line of the center of the guide wheel; when the molybdenum wire moves, the tangent point position of the molybdenum wire on the upper and lower guide wheels changes, and the actual position of the molybdenum wire is offset compared to when the molybdenum wire is vertical. The larger the angle, the greater the offset. At this time, the offset needs to be compensated. For example, a compensation method for taper cutting for wire cutting processing described in Chinese Patent No.: "202110088100.4" provides a method for compensating for offset. However, the compensation process is complicated and cumbersome, and each time the molybdenum wire moves an angle, data compensation needs to be performed through calculation in the wire cutting control software to improve the accuracy of the guide wire tilt, which is cumbersome to operate. At the same time, after compensation, angle errors may occur in the future due to insufficient accuracy. Summary of the invention
