Description
Technical field
The invention belongs to electroplating technology field, be specifically related to a kind of stationary fixture of soft material plating piece matrix.
Background technology
Plating piece matrix general in electroplating engineering is all mechanically resistant material, not yielding, is therefore all to adopt hanger to fix plating piece.The basic demand of hanger has enough physical strengths, can bear the weight of plating piece, has good electroconductibility, and electric current can flow uniformly through whole plating piece, easy to loading and unloading, lightweight.Plating piece hook hangs or is fixed on (" electroplating technology handbook ", the volumes such as Zeng Hualiang, 1994) on hanger.
Foamed metal is a kind of material with conspicuous characteristics, there is tridimensional network, porosity is high, and specific surface area is large, and current reasonable preparation method is electrochemical plating (Zhang Qiuli etc., non-ferrous metal, 2007, phase in year the 5th, 40-42 page), usually after pre-treatment, in required metal salt solution, by plating, metal is separated out on foam with urethane foam, finally form foamed metal material.Because porous plastics is soft material, even if after pre-treatment, still yielding soft state before plating, general Electropolating hangers can not fix 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, intactly metal plating can be obtained evenly by the mode of plating in Foam Plastic Surface.
A kind of stationary fixture of soft material plating piece matrix, electrically-conductive coil 6 is pressed in the surface of plating piece matrix 5 by bolt 3 and nut 4 by cover plate 2, a circle groove is had inside cover plate 2, be connected with base 1 with nut 4 by bolt 3, electrically-conductive coil 6 is hidden in stationary fixture inside, the outside silicone gasket 7 of base 1 and cover plate 2 seals, and has a circle perpendicular to the bossing of base 1 plane, be fixed on base 1 by plating piece matrix 5 by flexible rubber ring 8 inside base 1.
Described base 1, cover plate 2, bolt 3 and nut 4 is plastic material.
The medial surface of described base 1 and cover plate 2 is outside inclined-plane upwards.
When using stationary fixture of the present invention, first plating piece matrix is covered in the projection of base, if soft material, then with flexible rubber ring in the side of projection by it around fixing; Then electrically-conductive coil suitable for size is placed on plating piece matrix surface, and adds in chassis outer side the elastic washer that thickness is suitable; Finally aim at pedestal lobe with lid panel notches electrically-conductive coil and plating piece matrix are compressed, and with plastic bolt and nut base and cover plate compressed and link together, just can be put in plating solution afterwards and carry out electroplating operations; Fixture is generally vertical to be placed in coating bath, and plating solution liquid level the plating piece matrix upper limb be not exposed to outside fixture, and the wire connecting 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 up of rigid plastics, and acid-alkali-corrosive-resisting, is applicable to all kinds of electroplate liquid.Base of the present invention and cover plate Outboard Sections have a circle direct contact surface, with the corrosion-resistant washer sealing of elasticity between two sides, can be sealed in fixture by plating piece matrix border, completely eliminate plated edge effect; Base and cover plate are all ring structure, groove corresponding inside the bossing inside base and cover plate is relied on to be fixed by plating piece matrix Outboard Sections, electrically-conductive coil is pressed on plating piece matrix surface simultaneously, ensures that coil and plating piece matrix have and contact closely and good electroconductibility; Coil, much larger than the diameter of electrically-conductive coil wire used, can be wrapped in fixture inside, greatly reduce the degree that metal ion in plating solution is separated out on wire by pedestal lobe and lid panel notches width; Certain space is left in the side of pedestal lobe and lid panel notches, to hold the fixing flexible rubber ring of plating piece matrix and the extension of electrically-conductive coil; When clip vertical is placed in coating bath, outside inclined-plane is upwards made in upper inner face, is beneficial to discharge bubble, and avoiding bubble to accumulate in plating piece surface affects electroplating effect.
