The utility model has simple integral structure and scientific and reasonable design, solves the existing problem of the prior electroplating of the mandrel during the production process, enhances the current density and the electric-field intensity of electroplating, improves the production efficiency of the electroplating, and can perfectly satisfy the electroplating requirements of the mandrels.
Description
Technical field
The utility model belongs to the electroplating processes field, especially a kind of plating core rod negative electrode coupling device that draws.
Background technology
Plug is the warp tool in the seamless steel tube production, and length is longer, and is to work under most evil bad conditions such as high temperature, high pressure, high speed, therefore requires the technical qualification of plug processing and fabricating very high.Mandrel surface chromium plating is exactly in order to improve plug wear resisting property in use, to require the chromium coating of mandrel surface indeformable under the effect of thermal stresses and stress simultaneously, do not come off, and it is higher therefore mandrel surface to be handled galvanized technical requirements.At present, to the plating of plug, still adopt traditional negative electrode, anode mode, negative electrode connects plug, and anode connects plating tank, and the yin, yang ion in the electroplate liquid is subjected to electric field action generation steady shift, thereby realizes the even chromium plating of mandrel surface.
Existing plug negative contact is the negative electrode plectane that adopts a connection cathode power, adopts the mode of end face contact to link together by bolt and plug.Because the front end of plug is the taper type structure, bolt hole accounts for again than big area in addition, and the area of itself and negative electrode plectane contact surface is less, its conductivity is reduced, cause the current density of plug little, thereby influenced electroplating efficiency and quality, prolonged electroplating time.
In addition, existing plug electroplate be one one interrupted galvanized, the existing plating negative contact also can only be applied in a plug, production efficiency is low, can not satisfy the needs that modernization industry is produced.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of plating core rod negative electrode coupling device that draws is provided, and this coupling device can realize that the electrode of end face and conical surface is connected and realizes connection between the plug with plug.
The purpose of this utility model is achieved in that
A kind of plating core rod negative electrode coupling device that draws, comprise cathode disk, cathode disk connects cathode power, in the made central axis hole of cathode disk, be coated with bolt, the bolt co-axial plug that is connected with a joggle, it is characterized in that: coaxial installation one electrode sleeve between cathode disk and plug, this electrode sleeve middle part is shaped on the cone tank that matches with the plug conical surface, and cathode disk, plug, the coaxial employing bolt of electrode sleeve are installed.
And, also attach one deck sheet copper on the groove face of described electrode sleeve cone tank between electrode sleeve and plug.
And described cathode disk is a U-shaped dish structure, and two upright dishes of this U-shaped dish are connected with two electrode sleeves respectively, the coaxial plug of installing respectively of electrode sleeve, and two upright dishes of U-shaped dish, two plugs, two coaxial respectively employing bolts of electrode sleeve are installed together.
Advantage of the present utility model and positively effect are:
1, this negative electrode coupling device has increased electrode sleeve between cathode disk and plug, the made cone tank of this electrode sleeve contacts with plug conical surface formation face, and on the groove face of cone tank, attach one deck sheet copper, increased the contact area of electrode and plug, thereby effectively improved the current density of plug, strengthen strength of electric field, improved the electroplating efficiency and the quality of plug.
2, the cathode disk of this negative electrode coupling device is made the U-shaped structure, can realize that the electrode between adjacent two plugs connects, and has improved production efficiency, has realized the galvanized serialization production of plug.
3, the utility model one-piece construction is simple, and design science is reasonable, has solved the problem that exists in the existing plug plating production process, has strengthened galvanized current density and strength of electric field, has improved galvanized production efficiency, can perfect satisfy the plating requirement of plug.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described; Need to prove: present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of plating core rod negative electrode coupling device that draws comprises cathode disk 1, and this cathode disk connects cathode power, is coated with bolt (shown in the dotted line) in the made central axis hole 4 of cathode disk, the bolt co-axial plug (shown in the dotted line) that is connected with a joggle.Innovative point of the present utility model is:
1, coaxial installation one electrode sleeve 2 between cathode disk and plug, this electrode sleeve middle part is shaped on the cone tank that matches with the plug conical surface, contacts with plug conical surface formation face to realize this cone tank.In order to improve the contact effect, on the groove face of cone tank, also attach one deck sheet copper 3, to improve the current density of plug, strengthen strength of electric field.
In order to improve conductive effect, electrode sleeve adopts brass to make.
2, cathode disk is made U-shaped dish 5 structures, and two upright dishes of this U-shaped dish are connected with two electrode sleeves respectively, and its mode of connection is identical with cathode disk.Can realize that thus the electrode between adjacent two plugs connects, and has realized the galvanized serialization production of plug.
Principle of work of the present utility model is:
Electroplating cathode joint for single plug is sleeved on electrode sleeve on the plug, and coaxial again by bolt installation cathode disk, the other end threaded engagement of bolt is installed in the threaded hole of plug.
For the continuous electroplating of adjacent two plugs, change cathode disk into the U-shaped dish, between two of the U-shaped dish upright dishes and plug, an electrode sleeve is installed respectively, the mode of connection between two upright coiling of electrode sleeve, plug and U-shaped dish are same as cathode disk.
