Description

Technical Field

[0001] The utility model relates to wire cutting equipment, in particular to a connecting rod type medium wire cutting machine tool with large taper. Background Art

[0002] Patent document CN106735647B discloses a large taper wire cutting machine tool, which adopts a wire guiding frame with a new structure. When machining a workpiece to be machined, the wire guiding frame can move in the front-back direction or in the left-right direction, so that the electrode wire deflects by a set angle to perform large taper cutting on the workpiece to be machined. During the movement of the wire guiding frame in the front-back and left-right directions, the electrode wire between the front upper guide wheel and the front lower guide wheel, the axis line of the upper wire guiding hole, and the axis line of the lower wire guiding hole are basically kept coincident, and the axis line of this section of the electrode wire is parallel to the axis line of the connecting rod. Only slight contact occurs between the electrode wire and the upper and lower wire guiding devices in the coaxial direction, so that the upper and lower wire guiding devices always play a stable and reliable guiding and positioning role for the electrode wire, thus preventing problems such as the wire guiding device being deeply cut, the electrode wire curling and breaking, resulting in damage to the wire guiding device and shortening of the service life of the electrode wire, and further improving the machining accuracy and the surface finish of the machining. However, the connecting rod adopted by it is composed of multiple rods and transmission structures, and its structure is relatively complex. After long-term operation, it is easy to loosen and deform, affecting the cutting accuracy. Therefore, it is necessary to optimize the structure of this wire cutting machine tool to overcome the above defects. Summary of the Utility Model
