Abstract
An electroplating hard chromium pin hole elimination device relates to the field of metal electroplating, and particularly to an electroplating device which is used for pin hole generation on a coating in hard chromium electroplating. The electroplating hard chromium pin hole elimination device comprises an electroplating solution tank (1) and electrodes (2). The following components are provided above the electroplating solution tank (1): a vibration motor (3), a vibration plate (4), a vibration spring device (5), a fixed base (6) and a workpiece suspension part (7). The vibration motor (3) is fixed on the vibration plate (4). The vibration plate (4) is connected with the fixed base (6) through the vibration spring device (5). The fixed base (6) is provided with suspension part through holes (7) and is fixed on an upper opening of the electroplating solution tank (1) through bolts. The workpiece suspension part (7) is fixed on the vibration plate (4) and extends to the electroplating solution tank (1) through the suspension part through holes (7) on the fixed base (6). Through continuously shaking the component in the electroplating production process, the generated hydrogen bubbles are removed quickly. The electroplating hard chromium pin hole elimination device has the following advantages: low production cost, stable quality and no pin hole on the coating.
Description
Technical field
The utility model relates to the Metal plating field, is specifically related to a kind of coating that prevents when being used for durionise and produces the electroplanting device of pin hole.
Background technology
Hard chrome plating is at the thicker chromium coating of various matrix surfaces plating one decks, and its thickness utilizes the characteristic of chromium to improve the hardness of part, wear-resisting, heatproof and performance such as corrosion-resistant generally more than 20 μ m.Hard chromium is because its high rigidity that has and wear resistance, and can increase the work-ing life of product greatly and be widely used in many industries, and the surface treatment of various component; As machine die, steam cylinder piston, measurer and drawing device etc.Its another purposes is restoring worn parts and cutting over-drastic workpiece, makes these part recyclings.The quality of coating directly has influence on the work-ing life and the working efficiency of part, and pin hole is again a difficult problem that often occurs in the coating, is difficult for overcoming.
During plating, separating out of oxygen can take place by behind the plating tank on the anode in electric current.Can separate out hydrogen on the negative electrode, hydrogen is after separating out on the negative electrode, and the cathodic area pH value is risen has increased surperficial tension force, often be air bubble-shaped and stick to cathode surface, cause this place's insulation, make metal ion not be stained with the place discharge of bubble hydrogen, and can only discharge around these bubbles.The bubble hydrogen long period of separating out is trapped in piece surface, the bigger workpiece of area particularly, the residing position of bubble is dark more, the tension force of solution surface is big more, bubble just is not easy to leave workpiece surface more, because the bubble long period is trapped in piece surface, and power line can't be passed through, bubble has formed pin hole gradually.
Summary of the invention
Technical problem to be solved in the utility model is: the durionise device that the low part coating surface free of pinholes of a kind of steady quality and production cost is provided.
Technical solution of the present utility model is: it comprises electric bath groove and electrode, described electric bath groove top is provided with vibrating device, vibrating device involving vibrations motor, oscillating plate, vibrating spring device, permanent seat and workpiece suspension part, vibrating motor is fixed on the oscillating plate, oscillating plate is connected with permanent seat by the vibrating spring device, have the suspension part open-work on the permanent seat and by being bolted to the suitable for reading of electric bath groove, the workpiece suspension part is fixed on the oscillating plate and by the suspension part open-work on the permanent seat stretches to the electrodeposit liquid bath.
Technique effect of the present utility model is: by continuous shake part in plating production process, the bubble hydrogen of generation is hightailed, it is low to have a production cost, the advantage of steady quality coating free of pinholes.
