Problems solved by technology

The existing electroforming methods used to prepare large-format and high-thickness flat electroforming plates usually adopt the method of planar electroforming. This method is difficult to control the uniformity of thickness, the equipment is relatively large, and it takes up a lot of space. The actual operation tougher

Abstract

The invention relates to an electroforming device, comprising a liquid collecting tank, an electroforming tank located in the liquid collecting tank, a cylinder with grooves on the horizontal fixed surface in the electroforming tank along the axial direction, a pinch roller in the groove, and a cylinder on the surface of the cylinder Two conductive rings are fixed in the axial direction. The end faces of both sides of the cylinder have short shafts along the axis. Both ends of the pressure roller are fixed on the short shafts through adjustable tensioning devices. There is a speed-regulating motor outside the liquid tank, and the output shaft of the motor is fixed with an output gear that meshes with the transmission gear. In the electroforming tank, two arc-shaped titanium baskets and two arc-shaped titanium baskets that are symmetrically distributed on both sides of the cylinder and coaxial with the cylinder are dynamically connected. Two arc-shaped cathode shielding baffles symmetrically distributed on both sides of the cylinder and coaxial with the cylinder. The invention can electroform large-scale flat casting plates or cylindrical metal casting plates; observe the conditions of electroforming products in real time, change electroforming parameters according to actual conditions, and monitor online; can make metal molds of various specifications according to actual needs; the manufacturing process is simple, Improve thickness uniformity, small footprint, low investment cost.

Description

technical field [0001] The invention relates to an electroforming device, which is especially suitable for electroforming duplication of large-sized metal cast plates. Background technique [0002] The principle of electroforming is the process of applying the electrodeposition theory in electrochemistry to make the required metal products by electrodepositing metal on the mold core and then separating the metal layer from the mold core. Using the electroforming process, it is possible to manufacture some special-shaped metal products that are difficult to manufacture by general machining methods, such as large-format, high-thickness flat electroformed plates, and the thickness range of the prepared electroformed plates is usually 0.1 mm ~ 0.6mm. The existing electroforming methods used to prepare large-format and high-thickness flat electroforming plates usually adopt the method of planar electroforming. This method is difficult to control the uniformity of thickness, the ...
