Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of processing equipment, in particular to a wire guide device of a wire cutting machine tool. BACKGROUND

[0002] The wire cutting machine tool is a special machine tool for material processing by using the principle of electric spark discharge. It uses a continuously moving guide wire as a tool electrode and removes workpiece material by high temperature generated by pulse discharge to achieve precision cutting. The wire guide device is the core component of the wire cutting machine tool, which is responsible for accurately guiding the movement of the guide wire. During the long-time moving cutting process of the guide wire, its diameter gradually decreases. When the diameter of the guide wire is smaller than the preset value, the guide wire needs to be stopped for use to avoid damage to the workpiece caused by wire breakage during the process. When the guide wire is automatically fed, it is transported to the wire barrel by the conveying device and is clamped on the wire barrel to complete the feeding. Whether the feeding on the wire barrel is completed is usually detected by energizing. An electrode is connected to the conveying device and the wire barrel. When the guide wire is clamped on the wire barrel, the electrode on the conveying device and the wire barrel forms a path through the guide wire, and then whether the guide wire is fed is determined by whether the electrode is connected. During the long-time use of the machine tool, the guide wire itself carries impurities such as cutting chip liquid or grease when moving in the conveying device, which causes the impurities to adhere to the inner wall of the conveying device. This makes the electrode on the conveying device and the wire barrel fail to form a loop due to the blockage of the grease after the guide wire is fed, and thus the electrode on the conveying device and the wire barrel fails to be connected. Even if the feeding is completed, the automatic feeding mechanism will repeatedly feed the guide wire due to the failure to detect the guide wire, resulting in waste of the wire.

[0003] Chinese patent CN115213505B proposes a wire guide mechanism for automatic threading of a wire cutting machine tool, which includes a guide wire tube, a wire supply and tension system arranged in sequence along the wire feeding direction, a wire feeding wheel for conveying the wire, a cutting mechanism, an upper machine head, a workpiece, a lower machine head, and a wire collecting wheel. A driving device is arranged on the machine tool to drive the guide wire tube to move towards the lower machine head. An open-eye die for clamping the wire is arranged in the upper machine head. The guide wire tube penetrates the upper machine head and the workpiece. A centering mechanism is arranged between the workpiece and the lower machine head to align the guide wire tube with the lower machine head. The wire feeding wheel is rotatably arranged on a sliding plate, and the guide wire tube is fixedly arranged on the sliding plate. The sliding plate is movably arranged on a bottom plate, and two sliding rails are fixedly arranged on the bottom plate.

[0004] However, the technical solution of the patent has the following problems:

[0005] The patent cannot improve the accuracy of guide wire detection after feeding is completed and the accuracy of guide wire diameter detection, and cannot clean the surface of the guide wire in real time to improve the service life of the guide wire.
