Embodiment Construction

[0022] Such as figure 1 As shown, the cathode 17 is connected to the positive pole of the power supply 18, the cathode plate 5 is connected to the negative pole of the power supply 5, and the electroforming solution is filled with a distance of 0.5 mm in the middle to form a loop. According to the principle of electrochemistry, Cu in the electroforming solution 2+ Under the action of an electric field, electrons are obtained on the cathode plate and reduced to atoms, which are finally deposited. The essence of numerical control selective electrochemical deposition rapid prototyping is to use the principle of electrochemical deposition to circulate a very high-concentration electroforming solution in the deposition tank to provide sufficient metal ions for deposition, and then connect the very fine anode to the positive electrode , the cathode plate is connected to the negative electrode, so that there is an electric field passing between the very thin cathode and anode, and th...

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. It combines computer, CAD / CAM, numerical control, laser, new materials, precision servo, physics and chemistry, etc. It is a high-tech that integrates modern advanced scientific and technological achievements in the field of engineering. This technology adopts the material accumulation method to directly mold the CAD data under the control of the computer to form complex parts at one time. According to the 3D design model of the product, the outline of the section of each layer is obtained by layering and slicing, and the production problem of the 3D p...
