Abstract

Vorrichtung und Maschine zum elektrochemischen Senken dadurch gekennzeichnet, dass auf einem Untergestell (1) aus Profilrohr oder einem Blechschrank eine Bearbeitungseinheit (2) und ein Steuerungs- und Generator-Schrank (3) sowie innerhalb des Untergestells (1) eine Filtereinheit (4) untergebracht ist.Device and machine for electrochemical sinking characterized in that housed on a base frame (1) made of profile tube or a sheet metal cabinet, a processing unit (2) and a control and generator cabinet (3) and within the underframe (1) a filter unit (4) is.

Description

Das bisher bekannte elektrochemische Abtragsverfahren basiert auf dem Faraday'schen Gesetz der Elektrolyse mit einer am Minuspol liegenden Elektrode und einem am Pluspol liegendem leitenden Werkstück in einem Elektrolyten.
Die Elektrolyte sind in der Regel wässrige Lösungen von Salzen.The previously known electrochemical removal method is based on Faraday's law of electrolysis with an electrode lying on the negative pole and a conductive workpiece lying on the positive pole in an electrolyte.
The electrolytes are usually aqueous solutions of salts.

Für die technischen Anwendungen, z.B. zum Erzeugen einer Formwerkzeug-Kavität, ist von Nachteil, dass der Prozessablauf zu einer Streuung des Elektrolysevorgangs führt und damit zu einer ungewollten Abbildungsveränderung.For technical applications, e.g. for producing a mold cavity, it is disadvantageous that the process sequence leads to a scattering of the electrolysis process and thus to an unwanted image change.

Zielsetzung der Erfindung ist eine Maschine und ein Prozessablauf zur Vermeidung der verfahrensbedingten Abbildungsfehler.The aim of the invention is a machine and a process flow to avoid the process-related aberrations.

Erfindungsgemäß werden hierzu folgende Maßnahmen und konstruktive Besonderheiten durchgeführt:

  • 1 (Vorderansicht) und 2 (Seitenansicht) zeigen schematisch die Hauptbaugruppen Untergestell (1), Bearbeitungseinheit (2), Steuerungs- und Generator-Schrank (3) und Filtereinheit (4).
According to the following measures and design features are performed for this purpose:
  • 1 (Front view) and 2 (Side view) show schematically the main subassembly subframe ( 1 ), Processing unit ( 2 ), Control and generator cabinet ( 3 ) and filter unit ( 4 ).

Die Abmessungen der Gesamtanlage betragen maximal Breite B 1600 mm, Tiefe T 900 mm und Höhe H 2000 mm, vorzugsweise B × T × H = 1223 mm × 753 mm × 1600 mm.
Das Untergestell (1) kann eine Konstruktion aus Profilrohren sein oder als Blechschrank konzipiert sein.
Die Bearbeitungseinheit beinhaltet eine servogesteuerte z-Achse (6), an deren Ende ein Spannsystem für die Werkzeugelektrode befestigt ist. Der freie Raum zwischen Spannsystem und dem Arbeitstisch (5) beträgt in der Regel 100 bis 300 mm, vorzugsweise 165 mm. Der Steuerungs- und Generator-Schrank (3) beinhaltet den Generator für gepulsten Gleichstrom und die Steuerungselemente für die z-Achse (6) und Filtereinheit (4). Die Filtereinheit kann ein- oder mehrstufig ausgeführt werden. Kernpunkt der Neuheit ist das Steuerungsmodul zur Regelung des Arbeitsspaltes aufgrund vorgegebener Prozessparameter.The dimensions of the overall system are maximum width B 1600 mm, depth T 900 mm and height H 2000 mm, preferably B × T × H = 1223 mm × 753 mm × 1600 mm.
The underframe ( 1 ) may be a construction of profile tubes or designed as a sheet metal cabinet.
The processing unit includes a servo-controlled z-axis (6), at the end of a clamping system for the tool electrode is attached. The free space between the clamping system and the worktable ( 5 ) is usually 100 to 300 mm, preferably 165 mm. The control and generator cabinet ( 3 ) includes the pulsed DC generator and the z-axis controls ( 6 ) and filter unit ( 4 ). The filter unit can be executed in one or more stages. The main point of the novelty is the control module for regulating the working gap based on given process parameters.
