Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, specifically to a wire feeding mechanism with an umbrella-shaped guide wheel. Background Technology

[0002] The lower lead arm of a medium-speed wire EDM machine is one of its core functional components. It is mainly used to lower, transport, and guide the wire. It is a key structure connecting the wire supply system and the cutting area. During the medium-speed wire EDM process, the machine tool needs to use the principle of electrical discharge to cut metal workpieces with high precision through continuous and stable wire movement. The lower lead arm can accurately control the wire transport path and tension to ensure that the wire reaches the cutting area according to the preset trajectory, thereby ensuring the accuracy of workpiece cutting.

[0003] The wire threading and splicing device of the lower wire arm in a medium-speed wire EDM is a functional component integrated on the lower wire arm that is specifically responsible for threading and splicing the wire. Its core function is to smoothly guide the wire from the wire feeding system to the subsequent transmission structure of the lower wire arm through the lower wire threading mechanism, and to complete the precise connection of the old and new wires in the scenario of wire replacement and breakage repair, so that the wire can continuously and smoothly enter the cutting cycle.

[0004] In practical applications, existing threading mechanisms can achieve the initial threading and conveying of the wire by setting up simple guide holes and roller structures. However, the wire may deviate or become entangled due to the lack of guidance, which reduces the service life of the threading mechanism and lowers work efficiency. Utility Model Content
