Abstract
The invention belongs to the electrochemical treatment of metallic surface, particularly a kind of electrolytic electrophoresis method is produced the technology and the equipment therefor thereof of coating.
Low-temperature-plating-iron is repaired old workpiece, former all the employing directly put into workpiece the coating bath plating, of poor quality, the present invention implements the circulating bath method for deep bore cylinder casing or hydraulic pressure of the colliery pillar that those are difficult for plating, having solved has many hydraulic pressure of the colliery pillars or the deep bore cylinder casing can not plating and scrap serious problem, improved workpiece plating quality, simple for process.
Description
The invention belongs to the electrochemical treatment of metallic surface, particularly a kind of electrolytic process or electrophoretic method are produced the technology and the equipment therefor thereof of coating.
At present, repair in the old workpiece technology at low-temperature-plating-iron, mostly be used for plating cylindrical and shallow bore hole workpiece for many years, its processing method is that old workpiece is directly put into the coating bath plating of switching on.It exists defective to be: in the workpiece plating bath because of annode area less than cathode area, iron ion replenishes not enough, bath concentration is poor gradually, until being forced to stop plating; The cathode surface bubble hydrogen becomes big gradually by little, breaks at last, and this process causes ion to be completely cut off by hydrogen, can not reduce on negative electrode, and the deposition of failing forms pockmark.Some deep bore cylinder casings or hydraulic pressure of the colliery pillar cylinder inner bore are badly in need of repairing, and its area is big, and hole depth, and coating requires thick, bring very big difficulty for the reparation of this type of workpiece, and in the past few years people are exploring, in research.
The objective of the invention is to change existing plating technic and device, make it simple, guarantee deep bore cylinder casing and hydraulic pressure of the colliery pillar cylinder inner bore repairing quality.
The object of the present invention is achieved like this:
Be dependent on workpiece in the plating process, progressive additive along with coating, concentration in the plating bath, the situation that ion degree, acidity reduce gradually, the present invention takes to make the way of plating bath at the workpiece internal recycle, plating bath constantly injects from the workpiece bottom, is generally 10～15 according to required thickness of coating of wear of work amount and coating deposition rate
/ hour, grasp degree of the executing time, reach the plating requirement to workpiece.
The present invention realizes that the plating bath circulation is by the acidproof recycle pump of driven by motor, connects liquid-inlet pipe.There is a vacuum breaker liquid-inlet pipe lower end, and plating bath is delivered to stifled dish by the fluid circulation tube.Stifled dish surrounding is equipped with the inclined hole at several 15 ° of angles, and the oblique unanimity of inclined hole makes plating bath form eddy flow.Plating bath injects in the workpiece in stifled dish hole, overflows through workpiece top, finishes the circulating bath technological process.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing.
Fig. 1 is a workpiece plater synoptic diagram.
This device comprises a motor (6), the acidproof recycle pump of driven by motor (5) connects liquid-inlet pipe (7), and there is a vacuum breaker liquid-inlet pipe lower end, plating bath is delivered to stifled dish (11) lining through drain pipe (9), stifled dish (11) surrounding is equipped with 15 ° of inclined holes, and plating bath sprays in the workpiece from inclined hole, and (4) are the location fulcrums, good anodes centre's stationkeeping, (3) be repaired workpiece, (1) anode, (2) wiring integrated circuit board.
The mode that the present invention circulates in the plating workpiece owing to the employing plating bath, so workpiece coating is even, reliable in quality. Particularly to those large tracts of land, deep hole plating workpiece, the inventor is through 60 test of many times, successfully lining φ 60～300mm, the hydraulic support of coal mine cylinder sleeve of dark 200～1500mm. Apparatus of the present invention are simple in structure, are easy to realize.
