Description
Technical field
The invention belongs to the electroplating technology field, be specifically related to a kind of stationary fixture of soft material plating piece matrix.
Background technology
General plating piece matrix is all mechanically resistant material in electroplating engineering, and is not yielding, is all therefore to adopt hanger to fix plating piece.The basic demand of hanger is that enough physical strengths are arranged, and the weight that can bear plating piece has good electroconductibility, and electric current can be crossed whole plating piece by uniform-flow, and is easy to loading and unloading, lightweight.Plating piece hangs or is fixed on hanger (" electroplating technology handbook, the volumes such as Ceng Hualiang, 1994) with hook.
Foamed metal is a kind of material with conspicuous characteristics, has tridimensional network, porosity is high, and specific surface area is large, and present reasonable preparation method is electrochemical plating (Zhang Qiuli etc., non-ferrous metal, 2007, year the 5th phase, 40-42 page), usually by plating, metal is separated out through after pre-treatment on porous plastics with urethane foam in required metal salt solution, form at last the foamed metal material.Because porous plastics is soft material, even through after pre-treatment, before plating or yielding soft state, general Electropolating hangers can not be fixed this plating piece matrix well.
Summary of the invention
The object of the present invention is to provide a kind of stationary fixture of soft material plating piece matrix, in order to can obtain evenly intactly metal plating on Foam Plastic Surface by the mode of electroplating.
A kind of stationary fixture of soft material plating piece matrix, cover plate 2 is pressed in electrically-conductive coil 6 on the surface of plating piece matrix 5 by bolt 3 and nut 4, there is a circle groove cover plate 2 inboards, are connected with nut by bolt 3 and are connected with base 1, electrically-conductive coil 6 is hidden in stationary fixture inside, the outside of base 1 and cover plate 2 is with silicone gasket 7 sealings, and there is a circle base 1 inboard perpendicular to the bossing on base 1 plane, by flexible rubber ring 8, plating piece matrix 5 is fixed on base 1.
Described base 1, cover plate 2, bolt 3 and nut 4 are plastic material.
The inclined-plane of the medial surface of described base 1 and cover plate 2 for outwards making progress.
When using stationary fixture of the present invention, at first the plating piece matrix is covered on the projection of base, if soft material, with flexible rubber ring in the side of projection with it around fixing; Then the electrically-conductive coil that size is suitable is placed on the plating piece matrix surface, and adds in chassis outer side the elastic washer that thickness is suitable; Aim at pedestal lobe with the cover plate groove at last electrically-conductive coil and plating piece matrix are compressed, and with plastic bolt and nut, base and cover plate compression are linked together, just can be put in plating solution afterwards and carry out electroplating operations; General vertical being placed in coating bath of fixture, the plating solution liquid level the plating piece matrix upper limb that is not exposed to outside fixture to get final product, and the wire that connects electrically-conductive coil is drawn from top.
Beneficial effect of the present invention: the base of stationary fixture of the present invention, cover plate and web member bolt and nut are all made by rigid plastics, and acid-alkali-corrosive-resisting is applicable to all kinds of electroplate liquids.Base of the present invention and cover plate Outboard Sections have a circle direct contact surface, with the corrosion-resistant packing ring sealing of elasticity, the plating piece matrix border can be sealed in fixture between the two sides, have eliminated the plating fringing effect fully; Base and cover plate are all ring structure, the inboard corresponding groove of the bossing of dependence base inboard and cover plate is fixed plating piece matrix Outboard Sections, simultaneously electrically-conductive coil is pressed on the plating piece matrix surface, guarantees that coil and plating piece matrix have to contact closely and good electroconductibility; Pedestal lobe and cover plate recess width be much larger than the diameter of electrically-conductive coil wire used, coil can be wrapped in fixture inside, greatly reduces the degree that in plating solution, metal ion is separated out on wire; Certain space is left in the side of pedestal lobe and cover plate groove, to hold the fixedly flexible rubber ring of plating piece matrix and the extension of electrically-conductive coil; When clip vertical was placed in coating bath, the upper inner face was made the inclined-plane that outwards makes progress, and was beneficial to the discharge bubble, avoided bubble to accumulate in the surperficial electroplating effect that affects of plating piece.
