Technical field
The utility model relates to electroplating device, relates in particular to a kind of decorative plastic and electroplates with supplementary anode round trip flight bar.
Background technology
The general electro-plating method of decorative plastic electroplating industry is to place metal anode in the plating tank both sides at present, and the middle dress extension of cell body as negative electrode, is utilized redox principle that the metal ion reduce deposition is arrived and plated piece surface by the plating part under direct supply.Its thickness of coating be subject between anode and cathode distance affects and have larger difference, the short thickness of distance increases, otherwise reduces.Therefore for the especially part of deep hole shape of complex surface is arranged, its thickness of coating is widely different, thereby causes the deficiency of the performances such as corrosion resistance, high-low temperature resistant environmental performance of coating surface.
The utility model content
The purpose of this utility model, the problem existed in order to solve above-mentioned prior art exactly, provide a kind of decorative plastic to electroplate with supplementary anode round trip flight bar.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of decorative plastic is electroplated with supplementary anode round trip flight bar, comprise supplementary anode hanger and supplementary anode round trip flight bar, the supplementary anode hanger comprises main hook and auxiliary hook, and supplementary anode round trip flight bar comprises and mainly flies to cling to bar and auxiliaryly fly to cling to bar; Main hook flies to cling to bar and is connected as cathode portion with main, and auxiliary hook flies to cling to bar and is connected as the supplementary anode part with assisting; The master flies to cling to bar and assists to fly to cling between bar insulate and fixes, and between main hook and auxiliary the hook, by the hanger insulation spacer, is connected and fixed; Be connected with the hanger bound feet on main hook, on auxiliary hook, be connected with supplementary anode, hanger bound feet and supplementary anode are in the same way near arranging.
Described supplementary anode part also comprises supplementary anode, supplementary anode copper pigtail, supplementary anode seat, auxiliary bar and the link copper bar of flying; The supplementary anode seat is connected with the supplementary anode copper pigtail, assists to fly to cling to be arranged on the supplementary anode seat, and the link copper bar is connected to assist and flies bar and assist to fly to cling between bar; Described supplementary anode partly forms anode passage by supplementary anode copper pigtail and rectifier anodic bonding.
Described cathode portion also comprises hanger bound feet, copper pigtail, cathode block and the main bar that flies; Cathode block is connected with copper pigtail, and the master flies to cling to be connected on cathode block and to fly to cling to bar with the master and is connected, and described cathode portion connects into cathode passage by copper pigtail and rectifier negative electrode.
Described main hook, hanger bound feet, auxiliary hook, supplementary anode form integral type supplementary anode hanger by the hanger insulation spacer.
The utility model, owing to having adopted above technical scheme, has following advantage and disadvantage:
1, the thickness of coating for deep hole shape part or concave face part can be consistent with other normal surface thickness of coating, thereby promote the performances such as piece surface is anticorrosive, and prior art can not be accomplished this point on thickness.
2, owing to having designed the round trip flight bar, the supplementary anode hanger is free to extension, connects the supplementary anode electric current without artificial after moving to plating tank at hanger, thereby realizes the production automation, reduces labour intensity, enhances productivity.
The accompanying drawing explanation
Fig. 1 is that the utility model decorative plastic is electroplated the structural representation with supplementary anode round trip flight bar.
Embodiment
Referring to Fig. 1, decorative plastic of the present utility model is electroplated with supplementary anode round trip flight bar, comprise supplementary anode hanger and supplementary anode round trip flight bar, the supplementary anode hanger comprises main hook 7 and auxiliary hook 16, and supplementary anode round trip flight bar comprises and mainly flies to cling to bar 6 and auxiliaryly fly to cling to bar 15.Main hook 7 flies to cling to bar 6 and is connected as cathode portion with main, and auxiliary hook 16 flies to cling to bar 15 and is connected as the supplementary anode part with assisting; Main fly to cling to bar 6 and auxiliary to fly to cling between bar 15 insulation fixing, main hook 7 is connected and fixed by hanger insulation spacer 19 with assisting between linking up with 16; Be connected with hanger bound feet 18 on main hook, on auxiliary hook, be connected with supplementary anode 17, hanger bound feet and supplementary anode are in the same way near arranging.
Supplementary anode in the utility model part, except auxiliary hook 16 flies to cling to bar 15 with auxiliary, also comprises supplementary anode 17, supplementary anode copper pigtail 26, supplementary anode seat 10, auxiliaryly flies to cling to 8 and link copper bar 11.Wherein, supplementary anode seat 10 is connected with supplementary anode copper pigtail 26, auxiliary fly to cling to 8 and is arranged on supplementary anode seat 10, and link copper bar 11 is connected to and auxiliaryly flies to cling to 8 and fly to cling between bar 15 with assisting; This supplementary anode partly forms anode passage by supplementary anode copper pigtail 26 and rectifier anodic bonding.
Cathode portion in the utility model, except main hook 7 flies to cling to bar 6 with main, also comprises that hanger bound feet 18, copper pigtail 4, cathode block 2 and master fly to cling to 1.Wherein cathode block 2 is connected with copper pigtail 4, main fly to cling to 1 and is connected on cathode block 2 and flies to cling to bar 6 and be connected with main, and this cathode portion connects into cathode passage by copper pigtail 4 and rectifier negative electrode.
Main hook 7 in the utility model, hanger bound feet 18, auxiliary hook 16, supplementary anode 17 form integral type supplementary anode hanger by hanger insulation spacer 19.
Shown in figure, 3 is the cathode block insulcrete, and 5 fly to cling to insulated fixing support for assisting, 9 is spring, 12 fly to cling to the bar standing screw for assisting, and 13 fly to cling to the bar fixation clip for assisting, and 14 is the auxiliary bar insulation spacer that flies to cling to, 20 is the supplementary anode seat support, 21 is supplementary anode seat support standing screw, and 22 is supplementary anode seat support insulcrete, and 23 is supplementary anode seat support fixation clip, 24 is insulation covering, and 25 fly to cling to the bar insulated fixing support for assisting.
Workpiece principle of the present utility model is, product is fixed on hanger bound feet 18, and supplementary anode 17 is inserted in the product deep holes, and the distance between deep hole internal surface and anode shortens greatly thus.Can obtain the effect of even thickness during plating.Wherein mainly fly to cling to 1, mainly fly to cling to bar 6, auxiliaryly fly to cling to 8, link copper bar 11, auxiliaryly fly to cling to bar 15 and fly to cling to insulated fixing support 5 and auxiliaryly fly to cling to the fixing supplementary anode round trip flight bar part that forms of insulation such as bar insulated fixing support 25 by auxiliary, thereby can realize free exchange on the plating tank position arbitrarily.
