Description

Technical Field

[0002] Wire cutting is a processing method that uses a continuously moving thin metal wire (called electrode wire) as an electrode to perform pulse spark discharge to erode metal and cut the workpiece into shape.

[0003] Wire cutting tooling refers to the fixtures, fixtures or other auxiliary tools used in wire cutting processing. Their function is to ensure that the workpiece maintains a stable position during the processing so as to obtain accurate cutting size and shape. In actual use, the type of tooling needs to be adjusted according to different types of workpieces.

[0004] The existing inclined handrail cover plate workpiece is fixed on the wire cutting platform, and the front and rear lead screws are moved to visually observe the fit between the molybdenum wire and the part, and then the parts are locked and fixed for wire cutting processing. Since the parts are moved back and forth by manually cranking the handle to visually observe the fit between the molybdenum wire and the part, it is necessary to check repeatedly after adjusting the parallelism once. It takes a long time to adjust the straightness of the parts, especially at night when the line of sight of the parts is poor, and the adjustment time is even longer. In addition, the heights on both sides of different inclined handrail cover plate workpieces are different. When the inclined handrail workpiece is padded, it is necessary to add pads multiple times according to the actual height, and it is impossible to directly adjust according to the height of the workpiece. Therefore, a wire cutting tool is proposed to solve the above problems. Utility Model Content
