Abstract
The utility model relates to a long shaft rotary type electroplating hard chromium machine, comprising an electroplating tank (1), a bracket (2), a transmission system A, a connection shaft system B and two identical electrode systems C. The utility model is in the shape of a horizontal type structure. A workpiece needed to be electroplated (such as a water roll damping roller (13)) is installed between the left connection shaft (9) and the right connection shaft (10) of the connection shaft system B. The workpiece needed to be electroplated is submerged in electroplating solution and rotated, and thus the purpose of uniform coating is obtained.
Description
The utility model relates to a kind of major axis rotary electric hard chrome plating machine.Be applicable to that printing machinery, textile manufacturing machine, petroleum machinery and coal mine machinery etc. need the long-axle workpieces of durionise.
The offset press damping roller is the more typical workpiece that needs in the hard chrome plating workpiece.
The offset press damping roller is the strength member of offset press feeding apparatus.Damping roller there is a particular requirement, must hydrophilicly scolds China ink, always adopt the method for weldless steel tube plating hard chromium on surface to reach this requirement.But the working conditions of damping roller is very abominable, and it is that to be immersed in pH value be in 4～5 the acidic solution, very easily to cause galvanic corrosion.Damping roller in the use is nearly 4～5%, the phenomenon that hard chrome coating peels off occurs.
Theoretical analysis shows that the durionise layer itself has map cracking, causes crevice corrosion easily.The way that solves is certain thickness of coating to be arranged, to reduce the porosity of coating.But add thickness coating and can produce the even problem of a uneven coating again.
When coating is 0.03～0.05 millimeter thin layer, can guarantee that coating is more even, but the coating porosity is serious.When coating surpassed 0.05 millimeter, porosity reduced, and also may reduce to zero, but uneven coating is even, wants ground finish after the plating, and enough grinding allowances will be arranged.Because the grinding stress that even plating stress that produces of uneven coating and ground finish produce can cause a series of stress corrosion, causes chromium coating to peel off.
Theoretical analysis and practice simultaneously shows that reasonably thickness of coating should be 0.08～0,12 millimeters.
Common major axis durionise method is in the static immersion plating liquid of major axis, to be called quiet hard chrome plating.Coating is very inhomogeneous, and thickness difference can reach 0.3 millimeter, and grinding tolerance can reach 0.3～0.5 millimeter, and generalized case is that quiet chromed hardened speed is per hour 0.01 millimeter, plates a water rod and wants 30～40 hours.Production efficiency is very low.
It is rotary electric hard chrome plating mechanism that task of the present utility model is to change common quiet hard chrome plating.
Illustrate in conjunction with Fig. 1 and Fig. 2 how task of the present utility model realizes.
Fig. 1 is the structure diagram of major axis rotary electric hard chrome plating machine of the present utility model.
Fig. 2 is the A-A sectional view among Fig. 1.
Long axle rotary type electroplating hard chromium machine of the present utility model is except the foundation structures such as electroplating bath (1), support (2), and all the other mainly are made up of three parts. Namely formed by transmission system A, electrode system C that the B of connecting axle system is identical with two.
Transmission system A passes to gear (6) to power by motor (3), decelerator (4), and gear (6) is installed on the output shaft (5) of decelerator (4). By idle wheel (7), gear (8) power is passed to the connecting axle system then. Idle wheel (7) is installed on the axle (27), and the axle water bag (28) of bolster (27) is fixed on the outside of left side seal box (14). Gear (8) is installed on the left connecting axle (9).
The B of coupling shaft system by left coupling shaft (9), support the bearing bag (11) of left coupling shaft (9), right coupling shaft (10), the bearing bag (12) of support right coupling shaft (10) is formed.Water rod (13) is installed between left coupling shaft (9) and right coupling shaft (10).
Water rod (13) promptly is a workpiece of wanting durionise.
About electrode system C divides two ones, structure is identical.
Watertight chest (14) is arranged among the electrode system C.On watertight chest (14) top bolster (15) is arranged, be fixed with battery lead plate (16), (17) and (18) at bolster (15) middle part.The upper end (19) of battery lead plate (16) is stretched out ， And from watertight chest (14) top and is hook-type, hangs on the electrode thick stick (20).Battery lead plate (17) and (18) are stretched in the watertight chest (14), and the lower end of two battery lead plates (17) and (18) is formed forked, in the inboard of forked lower end electrode (21) and (22) is housed respectively.Middle part in two electrodes (21) and (22) forms a circular hole, and the radius R of this circular hole coincide with the diameter of the left coupling shaft (9) that passes through this circular hole, right coupling shaft (10).Respectively there are a bolt (23) and (24) in the upper and lower part of two electrodes (21) and (22).Bolt (23) and (24) are fixed in the threaded hole of electrode (21) by the via hole on battery lead plate (17) and the electrode (22).In the outside of battery lead plate (17), respectively be with a spring (25) and (26) in the socket cap inboard of bolt (23) and (24).
Left side coupling shaft (9) passes left side watertight chest (14).Right coupling shaft (10) passes right side watertight chest (14).
Bearing bag (11) is fixed on the outside of left side watertight chest (14).
Bearing bag (12) is fixed on the outside of right side watertight chest (14).
Major axis rotary electric hard chrome plating machine of the present utility model is horizontal type structure.
The Lower Half of the watertight chest (14) of idle wheel (7), gear (8), the B of coupling shaft system, two electrode system C is immersed in the electroplate liquid.
Electric motor (3) energising, damping roller (13) rotates in electroplate liquid.
The effect of spring (25) and (26) is to make electrode (21) and (22) to tie down left coupling shaft (9) and right coupling shaft (10), and electric current then passes on left coupling shaft (9) and the right coupling shaft (10) from electrode thick stick (20), battery lead plate (16), (17) and (18), electrode (21) and (22).
Select the rotating speed of best damping roller (13), on damping roller (13) surface, produce uniform pole effect, thereby reach the uniform purpose of durionise layer.
