Numerical control selected area electrochemical deposition rapid forming method and apparatus

Abstract

The invention discloses a digital control selecting area electrochemical deposition rapid molding method and a device. A worktable moving in the X direction and a worktable moving in the Y direction are arranged on a worktable of a machine tool, wherein, a sediment chamber provided with a cathode plate inside is arranged on the worktable in the Y direction, an anode is arranged at the lower end of an upright post moving in the Z direction and is inserted into the sediment chamber, an electroforming solution is sprayed out from a nozzle to the cathode plate, and a computer control system controls the relative position of the cathode and the anode, the moving speeds of three electric motors, the on and off of the power supply and the size of the sediment current. The electroforming solution with high concentration is added circularly, thereby providing sufficient metal ions for the sedimentation, and then the anode is connected with a positive electrode, the cathode is connected with a negative electrode; therefore, an electric filed is formed between the ultrathin cathode and the anode, and metal is sedimentated under the anode. The method combines the electroforming basic theory and the rapid molding technology, sufficiently uses the characteristics of the rapid molding technology and the electrochemical deposition technique, and can be directly used for manufacturing metal element products with high quality and high accuracy.

Description

technical field

[0001] The invention relates to an electroforming technology and a rapid prototyping technology, in particular to a method and a device for a rapid prototyping method and device of numerically controlled selective-area electrochemical deposition. Background technique

[0002] Rapid prototyping technology (Rapid Prototyping, RP) is a new type of manufacturing technology produced and developed in the early 1980s.
