Embodiment Construction
[0013] The present invention designs a current-leading device for immersing both the cathode of the rotor and the rotating pair in the electroforming bath liquid during the electroforming process, such as image 3 Schematic shown. The present invention firstly according to Figure 4 Connect the rotating body cathode 3 and the conductive ring 2 with a flexible wire 10 . connection method such as Figure 5 , insert one end of the flexible wire 10 into the holed bolt 12 and the tapered clamping piece 11, then tighten the holed bolt 12, press the tapered clamping piece 11, make it clamp the flexible wire, apply glue to the exposed part, etc. Measures insulation treatment. After the installation of the whole device is completed, the cathode shaft rotates, and the conductive ring 2 is driven to rotate synchronously through the flexible wire 10 . During electroforming, the conductive ring 2 is connected to the negative pole of the power supply, and the cathode 3 of the rotating b...

The invention provides a rotation and electricity-leading device with a rotary cathode and a revolute pair immersed in an electroforming solution, and belongs to the field of electroforming machining. The rotation and electricity-leading device comprises the rotary cathode (3), a cathode rotating device and an electricity-leading device, wherein the cathode rotating device comprises a motor (6) fixed on a bracket (5) above an electroforming solution groove (1), and a transmission gear set mounted in the electroforming solution groove (1); a first-grade gear (7) of the transmission gear set is connected with the motor (6); a final-stage gear (9) of the transmission gear set is connected with the rotary cathode (3); and the electricity-leading device is formed by a conductive ring (2) mounted on the bracket (5), a flexible lead wire (10) and connectors for respectively connecting the flexible lead wire (10) with the conductive ring (2) and connecting the flexible lead wire (10) with the rotary cathode (3). According to the rotation and electricity-leading device disclosed by the invention, the disadvantages that the bearing capability of the cathode suspension type rotary revolute pair is large and the service life is short can be avoided; and the difficulty that conventional cathode horizontal type rotary electrical conduction needs to effectively seal the revolute pair can be solved.
Description
technical field [0001] The invention relates to a rotating and current-leading device in which a cathode of a revolving body and a rotating pair are immersed in an electroforming liquid during an electroforming process, and belongs to the field of electroforming processing. Background technique [0002] Electroforming technology is the forming process of parts using the principle of electrodeposition of metal cations on the surface of the cathode. In the electroforming process, the electroforming cathode is connected to the negative pole of the power supply, and the anode is connected to the positive pole of the power supply, and forms a closed loop of electroforming with the power supply and electroforming liquid. . In order to ensure the uniformity of the thickness of the electroforming layer, the rotary workpiece must be rotated during the electroforming process. But for the electroforming of large rotary structural parts, traditional hanging rotary such as figure 1...
