Abstract
The utility model relates to a sealing system of a core bar chromium-plated equipment, comprising a titanium material sleeve, an electric plating box flange disc, an insulating sleeve sheathed at a gap between the titanium material sleeve and the electric plating box flange disc, a sealing device arranged in the electric plating box flange disc and the titanium material sleeve, a pressure plate and a flange disc cover; and the sealing device is formed by a sealing front flange, sealing pieces, a sealing hub and a sealing rear flange which are fastened by long and short double-head screw rods and nuts. The sealing system of the core bar chromium-plated equipment has the advantages that as the sealing device is arranged in the titanium material sleeve and the electric plating box flange disc, the plating solution of the core bar passing through each group of sealing pieces is less and less, also can flow into the electric plating box flange disc by a circular hole on the sealing device, and then backflow to a mother groove by a backflow pipe of the electric plating box flange disc, thus not only being capable of playing the role of plating-solution sealing, but also being capable of reducing waste of plating solution, and reducing the pollution of the plating solution to the operating environment. In addition, the sealing system also has the advantages of simple structure, and convenient replacement of the sealing device.
Description
Technical field
The utility model belongs to plug manufacturing technology field, particularly relates to a kind of tightness system of plug chrome plating equipment.
Background technology
Tube rolling comprises technologies such as perforation, tube rolling, sizing, and plug is the required axial workpiece of tube-rolling technique, and annual consumption is very big.Plug needs it is carried out chrome-faced after machining is finished, to strengthen its surface hardness.At present, the chrome plating equipment of plug manufacturing source mill is not only simple and crude, especially does very badly at the plating bath seal aspect, and the seal approach of its plating bath is to be equipped with three layers of soft pvc diaphragm seal of being close on the import and export position of chrome plating equipment.Flow out owing to have some acid solutions in the chromium plating treating processes unavoidably, cause sealing effectiveness undesirable, it is cumbersome to change the PVC diaphragm seal simultaneously, so not only cause the waste of plating bath, and the chromic acid that leaks belongs to toxic liquid, and polluted operating environment, therefore is difficult to reach the requirement of national environmental protection.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, good sealing effect, can antipollution plug chrome plating equipment tightness system.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the tightness system of plug chrome plating equipment, it is characterized in that: comprise titanium material sleeve, plating vat ring flange, be placed in insulation covering that titanium material sleeve and plating vat ring flange intermediate gaps place be used to prevent that electric current from leaking outside, be installed in tightness system, pressing plate and flange disk cover in plating vat ring flange and the titanium material sleeve, and hold out against by the screw that holds out against in the pressing plate outside; The sealing device be by sealing forward flange, diaphragm seal, sealed hub and sealing rear flange by long double threaded screw, lack double threaded screw and nut is fastening constitutes.
The utility model can also adopt following technical scheme:
Described tightness system and titanium material telescopic hold out against and also are provided with O-ring seal on the end.
Advantage and the positively effect that the utlity model has are: because the utility model adopts technique scheme, carry out in the chromium plating treating processes at plug, owing in titanium material sleeve and plating vat ring flange, tightness system is installed, can make the plating bath meeting of every group of diaphragm seal that plug passes through fewer and feweri, and the plating bath that flows through every group of diaphragm seal also can flow into the plating vat ring flange by the circular hole on the tightness system, return line through the plating vat ring flange flows back to female groove then, so not only can play the effect of plating bath sealing.Also can reduce the waste of plating bath, avoid the pollution of plating bath operating environment.In addition, the utility model also has simple in structure and changes tightness system advantage easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a schematic diagram of sealing device of the present utility model;
Fig. 3 is the utility model plating vat flange plate structure synoptic diagram.
Among the figure: 1, plug; 2, hold out against screw; 3, flange disk cover; 4, pressing plate; 5, plating vat ring flange; 6, tightness system; 6-1, sealing rear flange; 6-2, sealed hub; 6-3, diaphragm seal; 6-4, long double threaded screw; 6-5, short double threaded screw; 6-6, sealing forward flange; 6-7, O-ring seal; 7, insulation covering; 8, titanium material sleeve.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 3, the tightness system of plug chrome plating equipment, comprise the pressing plate 4 of tightness system 6 in flange disk cover 3, titanium material sleeve 8, plating vat ring flange 5, horizontally mounted titanium material sleeve 8 and the plating vat ring flange 5, pressed sealing device 6 and hold out against screw 2, the intermediate gaps place of described titanium material sleeve and plating vat ring flange is set with the insulation covering 7 that prevents that electric current from leaking outside, and has so promptly constituted the tightness system of plug chrome plating equipment.Titanium material sleeve 8 can play supporting sealing device and axial location effect, and described plating vat ring flange not only can play the effect of supporting sealing device, also can play the effect that plating bath is back to female groove.At pack into tightness system 6 and be used for insulating pressing plate 4 of plating vat ring flange one end, plating vat ring flange 5 is connected with flange disk cover 3 by bolt, and holds out against screw 2 by adjustment and hold out against pressing plate 4, with the effect of realization top tight sealing device 6.Described tightness system comprises sealing rear flange 6-1, sealed hub 6-2, diaphragm seal 6-3, sealing forward flange 6-6 and the O-ring seal 6-7 that is solidly installed by long double threaded screw 6-4, short double threaded screw 6-5 and nut, O-ring seal 6-7 is adjacent to the coupling end of tightness system and coating bath, and is close to titanium material sleeve 8 to play the effect of sealing.
Plug 1 passes the tightness system of plug chrome plating equipment when chromium plating, diaphragm seal on the tightness system is sealed around can being close to mandrel surface, therefore, the plating bath of the every group of diaphragm seal that pass through can be fewer and feweri, even also have a small amount of plating bath to overflow from the slit between diaphragm seal and plug, also can flow into the plating vat ring flange by the circular hole on the tightness system, the return line through the plating vat ring flange flows back to female groove then, and then plays the effect of plating bath sealing.
Claims (2)
