Abstract

The present invention relates to an electrocasting device capable of providing an electrolysis metal with uniform thickness and increased outside diameter accuracy for a core filament and obtaining a metal material with a fine diameter having a highly precise roundness and coaxial degree. An anode is printed in an electrolysis metal containing screen cage in an electrolysis metal containing chamber 16, and a cathode is printed in a core filament 13. The movement (movement of electric current) of the electrolysis metal electrolyzed in the electrolysis metal containing chamber 16 is regulated on the peripheral wall of the electrolysis metal containing chamber 16 and only flows out through a sharp-fine-shaped opening 16a. The flow of the electrolysis metal from the sharp-fine-shaped opening 16a to a passage 14 is restrained by the peripheral wall of the narrow passage 14, and reaches the core filament 13 at the passage 14, where the electrolysis metal will adhere on the core filament 13.

Description of the invention (l) 'The present invention is an electroforming device capable of producing fine-diameter metal constituent materials with high true roundness by using electroplating, especially regarding the electroforming device suitable for manufacturing hollow metal structural materials. , Is applicable to the manufacture of metal rings used at the connection of optical fiber and optical fiber, or the connection of optical fiber and optical element. The important part of the light source 彳 5: the metal ring, its shape is shown in Figure 8, the length L is about 10mm, the outer diameter D ^ 25 ~ 25mm, and the inner diameter d corresponds to the light specification (outer diameter 0.25 mm) It is a hollow shape prescribed at 0. 26 mm. The metal ring used to be the mainstream product in the past. However, because of the complicated manufacturing process and the efficient production of articles with high precision, the metal ring has been proposed in recent years to manufacture metal rings. In the case of a method for manufacturing a tubular metal constituent material by electroplating, for example, the method for manufacturing a narrow-bore hose disclosed in Japanese Patent Application Laid-Open No. 1 1-1 93485 can be exemplified.
