Abstract
Disclosed is a cadmium-plated positioning apparatus for the internal surface of a pipe fitting. The utility model is used for solving the problem that previously the cadmium-plated layer on the internal surface of the pipe fitting can not be controlled to obtain even electrodeposit. The utility model is composed of a fixing piece, an insulated piece and an internal positive electrode; wherein the insulated piece is arranged on the fixing piece and both ends of the internal positive electrode are connected with the insulated piece. The utility model has the advantages that even electrodeposit can be formed on the internal surface of the pipe fitting; the qualified rate of the pipe fitting cadmium-plating is improved and the production cost is reduced.
Description
Technical field:
The invention is the electroplating activity that is used for toward the cadmium plating of pipe fitting internal surface.
Background technology:
At present, adopt stainless steel anode, cadmium anode, plastic wire to electroplate, the electroplating operations process is very complicated; The technology supplementary product onsumption is more in the production process, the especially more uncontrollable even galvanic deposit of pipe fitting internal surface coating, and pipe fitting plating qualification rate is low, influences production schedule.
Summary of the invention;
The purpose of the invention provides a kind of pipe fitting internal surface cadmium plating layer that makes and obtains uniform galvanic deposit, improves the pipe fitting surface cadmium plating locating device of pipe fitting internal surface cadmium plating qualification rate; The purpose of the invention is to realize by following technical scheme: be made of mounting block, insulating part, inner anode, mounting block is made internal cavity lid formula structure, make installation insulating part hole at the center of lid, on the sidewall of lid formula structure, make through hole, open end in lid formula structure is made the step that concaves, insulating part is made inner anode hole and internal thread is installed, outside surface is made ledge structure, outside screw is made at the inner anode two ends, insulating part is installed on the mounting block installs in the insulating part hole, the inner anode two ends are installed in the installation inner anode hole on the insulating part.
The advantage of the invention: when adopting this device toward the cadmium plating of pipe fitting internal surface, be that two ends with pipe fitting are contained in the step that concaves that fastener openings end place makes, insulating part is installed on the mounting block, again with inner anode, be contained in the pipe fitting endoporus by the installation inner anode hole on the insulating part, pipe fitting fixed also and between the inner anode insulated; Inner anode makes inner anode be in the center of pipe fitting by the support of insulating part, therefore can obtain uniform electrically deposited cadmium coating, has therefore improved the qualification rate of pipe fitting internal surface cadmium plating, has accelerated production schedule; Because this apparatus structure is simple, production operation is simple, when having saved the galvanizer and the technology auxiliary material.
Description of drawings:
Fig. 1 is the pipe fitting internal surface cadmium plating positioning device structure synoptic diagram that pipe fitting is housed.
Embodiment:
Pipe fitting internal surface cadmium plating locating device; Constitute by mounting block 2, insulating part 3, inner anode 4.Mounting block is made internal cavity lid formula structure, promptly an end is shaped on top cover, one end is made opening, at lid is that the center of top cover is made the insulating part hole is installed, because make in the center in this hole, guarantee the center of insulating part, the center of the center of mounting block and pipe fitting 1 is coaxial, on the pipe fitting internal surface, could obtain uniform electrically deposited cadmium coating when therefore electroplating, on the sidewall of lid formula structure, make through hole, the quantity of through hole and diameter can be according to pipe fitting internal diameter and the decisions of actual cadmium plating technology, through hole can make pipe fitting endoporus internal solution can fully exchange circulation, and the place makes the step that concaves at lid formula structural openings end, and the step that concaves is that the pipe fitting two ends are fixed; Insulating part is made and the inner anode hole is installed and makes internal thread on hole wall, outside surface is made ledge structure, outside screw is made at the inner anode two ends, insulating part is installed on the mounting block installs in the insulating part hole, and the inner anode two ends are installed in the installation inner anode hole on the insulating part.
During the cadmium plating operation, mounting block is contained in the two ends of pipe fitting 1, insulating part is contained on the mounting block, inner anode is contained in the pipe fitting endoporus, two ends are fixed by screw thread and insulating part, simultaneously pipe fitting are compressed the location.After outer surface of pipe fittings protected, will locate with locating device, the pipe fitting after fixing immerses in the cadmium plating groove and carries out cadmium plating.
Insulating part is made with insulating material, and this case adopts glass-reinforced plastic material to make.
