２の開閉操作が容易である。FIG. 5 shows a cross section of a machined part being machined by a wire electric discharge machine. In the figure, 1 is a wire. 2 is work.
3 is a mount for mounting the work 2. A nozzle 4 is arranged above and below the work 2. Then, in order to prevent air discharge and remove the generated sludge, the working liquid 5 is supplied coaxially with the wire 1 from the nozzle 4 toward the working portion. At this time, the inner diameter of the nozzle 4, that is, the outer diameter of the supplied working liquid 5 is much larger than the outer diameter of the wire 1. Therefore, the distance g between the tip 6 of the nozzle 4 and the surface 7 of the workpiece 2
Is large, the working liquid 5 hitting the surface 7 is scattered in all directions. When the distance g is small, the machining liquid 5 is scattered horizontally along the surface 7. For this reason, four surfaces of the machining tank of the wire electric discharge machine are surrounded by covers to prevent the machining liquid 5 from scattering from the machining tank. As such a processing tank cover, there is one shown in FIG. 6 or 7.
That is, the processing tank cover shown in FIG. 6 is composed of a fixed cover 9 fixed to the processing tank 8 and a movable cover 10 which is lightweight and can be attached to and detached from the processing tank 8. I'm trying to surround it. Therefore, if the movable cover 10 is removed from the processing tank 8, a wide opening can be obtained, and the mounting base 3
The work inside the working tank 8 can be facilitated by fixing the work 2 to the workpiece or setting the wire 1 on the wire guide portion (not shown). The processing tank cover shown in FIG. 7 is fixed to the processing tank 8 and has four surfaces fixed to the processing tank 11.
And a movable cover 12 that is vertically movable relative to the fixed cover 11, and the notch 13 of the fixed cover 11 is closed by the movable cover 12. Therefore, it is not necessary to remove the moving cover 12 from the processing tank 8 and the moving cover 1
The opening and closing operation of 2 is easy.
しかしながら、第６図に示した構成の加工槽カバーの場

カバー１２と固定カバー１１とを重ねるから、固定カバ
ー１１の高さの半分以下しか開口部が得られず、加工槽
８内部での作業がやりにくいという問題点がある。However, in the case of the processing tank cover having the configuration shown in FIG. 6, a place for placing the moving cover 10 must be provided separately from the installation space of the wire electric discharge machine, and the working liquid 5 is placed on the inner wall of the moving cover 10. Processing liquid 5 because it adheres
If you place it on the floor without wiping it off, the floor will get wet. Further, in the case of the processing tank cover shown in FIG. 7, since the movable cover 12 and the fixed cover 11 are overlapped with each other, the opening can be obtained only at a half or less of the height of the fixed cover 11, and the work inside the processing tank 8 is There is a problem that it is difficult to do.
本考案の目的は、上記した課題も解決し、加工槽８から
の取外しが不要で、しかも広い開口部が得られる加工槽
カバーを提供するにある。An object of the present invention is to solve the above-mentioned problems, and to provide a processing tank cover which does not need to be removed from the processing tank 8 and has a wide opening.
上記した課題を解決するための手段を、本考案の一実施

8 and the cover (18) are divided into two and are connected by a hinge (20). Therefore, when the cover 17 is moved, the cover 17 can be bent also on the back side opposite to the opening of the fixed cover 15. Therefore, even if the space on the rear surface side of the fixed cover 15 is small, the opening can be widened. Since the cover (18) and the hinge (20) are not necessarily provided, the description thereof will be omitted in the following modified examples. Further, since the operation is the same as the above, the following description will be given based on the shape of the movable cover 17 and the shape of the fixed cover 15 with the cover being covered.
