Background
Numerical control wire cutting machines are generally classified into three types, namely a fast wire cutting machine, a medium wire cutting machine and a slow wire cutting machine, wherein the fast wire cutting machine is taken as an example, a wire electrode performs high-speed reciprocating motion, and the wire feeding speed is 8-10 m/s. The working principle is that the wire electrode passes through a pre-drilled small hole on a workpiece, the wire electrode is driven by a wire cylinder to reciprocate alternately through a guide wheel, the workpiece is arranged on a conductive workbench through an insulating plate, and the conductive workbench moves in two coordinate directions of a horizontal plane X, Y respectively according to a given control program to synthesize any plane curve track. The pulse power supply applies pulse voltage to the wire electrode and the workpiece, the wire electrode is connected with the negative electrode of the pulse power supply, and the workpiece is connected with the positive electrode of the pulse power supply. When an electric pulse is generated, spark discharge is generated between the wire electrode and the workpiece, the instantaneous elbow of the central temperature of the discharge channel can reach more than 10000 ℃, the workpiece metal is melted at high temperature, even a small amount of the workpiece metal is gasified, the working fluid part between the wire electrode and the workpiece is gasified at high temperature, and the gasified working fluid and metal vapor instantaneously and rapidly expand and have the characteristic of explosion. The thermal expansion and the local micro explosion throw out the melted and gasified metal material to realize the electric erosion cutting processing of the workpiece material.
In the wire cutting processing process, in order to prevent the wire electrode from damaging the machine parts, eye molds are respectively arranged on the upper side and the lower side of the processing platform, the eye molds are made of abrasion-resistant materials such as diamond, and the wire electrode is limited and pulled through the eye molds, so that the damage of the machine parts can be effectively prevented. Most of the eye molds are arranged at a fixed position, so that the stability of the eye molds can be ensured, and the influence on cutting precision caused by shaking during cutting is avoided. In order to meet the requirement of automatic realization of production equipment, automatic threading has become an important point in the research and development of the technology in the field, and in order to realize automatic threading, a threading channel needs to be built, and the wire electrode can realize automatic threading by utilizing the threading channel. At present, manufacturers at the front of the industry all utilize the lifting of a threading mechanism above a processing platform to realize the construction of a threading channel. In practical application scenarios, the workpiece is cut and then the waste falls, but in the current machine tool structure, in order to realize automatic threading, the processing platform and the lower threading mechanism must be as close as possible, which leads to easy occurrence of a clamping phenomenon, and if the workpiece and the lower threading mechanism reserve a sufficient blanking interval, automatic threading cannot be realized.
