摘要： A work liquid storage apparatus of an electric discharge machine having a work tank (2) for storing a work liquid (5) supplied by work liquid supply (6) with a workpiece (4) placed in the work liquid (5), the work tank having an opening (2a), a door (12) for opening and closing the opening (2a), and a seal member (10) for hermetically sealing space between the work tank (2) and the door (12) includes support plates (13) each being formed with a long hole (13a) in an up and down direction, fixing (14) for fixing the support plates (13) and the door (12), and arms (15) each being rotatably supported at both end parts with the work tank (2) and the support plate (13). Since the door (12) can be held at the position covering the lower end part of the opening (2a) of the work tank (2) and the position exposing the lower end part of the opening (2a), maintenance work and replacement work of the seal member (10) can be performed easily.
摘要翻译：一种放电机的工作液体储存装置，具有用于将由工作液体供应装置供给的工作液体（5）存储在放置在工作液体（5）中的工件（4）的工作罐（2），工件具有开口（2a），用于打开和关闭开口（2a）的门（12）和用于气密地密封工作箱（2）和门（12）之间的空间的密封构件（10）包括：每个在上下方向上形成有长孔（13a）的支撑板（13），用于固定支撑板（13）和门（12）的固定（14）和各自可旋转的臂在工作箱（2）和支撑板（13）的两个端部处支撑。由于门（12）能够保持在覆盖工作箱（2）的开口（2a）的下端部的位置和露出开口（2a）的下端部的位置，维护工作和可以容易地进行密封构件（10）的更换作业。

摘要： A wire electric discharge machining apparatus has a wire guide upper unit for slidably retaining a wire electrode above a subject to be machined, a wire guide lower unit for slidably retaining the wire electrode below the subject, an arm member for retaining the wire guide lower unit in a position opposite to the wire guide upper unit, a machining tank filled with machining solution in which the subject is immersed and having a long hole through which the arm member can pass and move, and a scaling unit for suppressing outflow of the machining solution from the long hole. The sealing unit has a sealing plate for blocking the long hole of the machining tank. The wire electric discharge machining apparatus has machining solution jetting unit for jetting the machining solution into a small gap formed between a peripheral portion of the long hole and the sealing plate.
摘要翻译：线放电加工装置具有用于将线电极可滑动地保持在待加工对象上方的导丝上部单元，用于将线电极可滑动地保持在被检体下方的线引导下部单元，用于保持导线下部单元在与导丝器上部单元相反的位置处，填充有被浸渍物体的加工液的加工槽，并且具有长孔，臂部件能够通过该长孔，以及用于抑制加工液流出的定标单元从长洞。密封单元具有用于阻塞加工槽的长孔的密封板。线材放电加工设备具有用于将加工溶液喷射到形成在长孔的周边部分与密封板之间的小间隙中的加工液喷射单元。
