Specifically, it is a high-speed reciprocating wire electric discharge machine tool open and close type guide wire water spray plate.

Background technique

As we all know, in the process of high-speed reciprocating WEDM processing, due to the high-speed operation of the electrode wire, the vibration and regular reversing of the electrode wire will cause the spatial position of the electrode wire to change, which will seriously affect the machining accuracy and surface quality. The threader is a key component to solve this problem. The wire guides used on the high-speed reciprocating wire electric discharge machine tool are currently mainly limited to two types: the limit rod and the ring. Limiting rod Because the electrode wire rubs on the limiting rod at high speed, it is easy to grind a groove on the surface of the limiting rod and the wrap angle between the electrode wire and the limiting rod is small, the limiting effect is poor, and more importantly Its structure can not achieve all-round limit, and its limit principle is shown in Figure 1. The ring-shaped wire guide can limit the electrode wire in all directions, so the limit effect is better, but under the high-speed friction of the electrode wire, the aperture will gradually increase, and the limit effect will gradually decrease. In addition, the ring-shaped guide wire Generally, the device can only limit the electrode wire with a certain diameter, because the aperture is generally only 10 larger than the electrode wire. , so it is extremely inconvenient to thread the electrode wire. The principle of the limit is shown in Figure 2, so it is necessary to improve the structure of the traditional wire guide.
