Description

The plating machine shakes

The utility model relates to a kind of electroplanting device, and particularly suitable is irregular, the plating of sheet, finding.

At present, method horizontal or the tilting barrel plating is generally adopted in the plating of finding, and it is to utilize the cylinder of rotation to drive little plating piece in it to roll and realize, but it deposits many shortcomings: (1) is because the obstruct of roller plate, the inside and outside concentration gradient of cylinder is bigger, and electroplating efficiency is low, and electroplating time is long; (2) bath voltage is higher, and the groove temperature rises fast; (3) be not suitable for the plating of sheet, tiny, irregular part.The CN88207916.6 Chinese patent improves this, add jet apparatus on the basis of horizontal barrel plating machine, the method for taking forced convection is to the jet flow that circulates in the cylinder, to reduce concentration difference gradient inside and outside the cylinder, but actual effect is undesirable, can not fundamentally solve the aforesaid drawbacks.

The purpose of this utility model is to overcome deficiency of the prior art, designs a kind of can the plating sheet, tiny, irregular part, and the electroplanting device that electroplating time is short, production efficiency is high.

The utility model is achieved in that it is made up of vibration source, vibrator, vibratory screening apparatus, coating bath and suspension bracket, wherein vibration source provides the electrical signal of adjustable vibrational frequency for the ternary vibrating motor, vibrator comprises machine sieve and ternary vibrating motor, machine sieve internal fixing ternary vibrating motor, top is suspension hook fixedly, and ring flange is arranged at the bottom.The vibratory screening apparatus middle part is a pipe handle, and pipe handle bottom is the sieve groove of upper shed fixedly, sieve bottom land mosaic cathode contact, and porose on its end and the wall, top is realized detachable fixing by ring flange and machine sieve.On the suspension bracket top arm suspension ring are arranged, vibrator and vibratory screening apparatus hang on the suspension ring of suspension bracket by suspension hook, and vibratory screening apparatus is suspended in the coating bath, and suspension bracket bottom and coating bath are fixed, and hang positive plate in the coating bath, and the sieve bottom land has the volution boss.

The utility model compared with prior art has following advantage: (1) because vibratory screening apparatus top opening is porose again on the end and the wall, so the inside and outside concentration difference of vibratory screening apparatus is very little, bath voltage is low, and current flowing is good, and electroplating time is short; (2) owing at the bottom of the vibratory screening apparatus volution boss is arranged, add the ternary vibration, make plating piece can make rotation and tumbling motion, so it can plate sheet, tiny, irregular part, and plating piece little wear, scratch and distortion; (3) by the control vibrational frequency, the fluctuation of thickness of coating can be controlled to minimum, improve the quality of plating piece greatly.

Be elaborated below in conjunction with accompanying drawing:

Fig. 1 is the utility model sectional view;

Fig. 2 is the utility model vibratory screening apparatus front view;

Fig. 3 is the utility model vibratory screening apparatus A--A sectional view.

The utility model is by vibration source, vibrator, vibratory screening apparatus, coating bath 15 and suspension bracket 1 are formed, as shown in Figure 1, wherein vibration source adopts step-down, rectification, filtering, mu balanced circuit, utilize silicon controlled rectifier to provide adjustable voltage signal for ternary vibrating motor 6, make the ternary vibrating motor can produce the vibration of different frequency, the machine of vibrator sieves 5 internal fixation ternary vibrating motors 6, on the output shaft 7 of ternary vibrating motor 6 eccentric block 8 is arranged, and be fixed on by bearing 9 on the ring flange 10 of vibrator bottom, the top of machine sieve 5 is suspension hook 3 and terminal stud 4 fixedly, the output signal of vibration source is connected ternary vibrating motor 6 by this terminal stud 4, the vibratory screening apparatus middle part is a pipe handle 13, the top fixed flange 12 of pipe handle 13, but fix by this ring flange 12 and the ring flange 10 realization demolitions of machine sieve 5, the bottom of pipe handle 13 is the sieve groove 14 of upper shed fixedly, 3 row's cathode contacts 19 are inlayed at the end of sieve groove 14, as Fig. 2, shown in 3, each cathode contact 19 usefulness is clipped in the copper coin 21 of sieve groove at 14 ends and realizes being electrically connected, rod iron 18 lower ends in pipe handle 13 and copper coin 21 are fixing, the upper end links to each other with cathode wire 11, and there is a volution boss 20 at 14 ends of sieve groove.On suspension bracket 1 roof suspension ring 2 are arranged, vibrator and vibratory screening apparatus hang on the suspension ring 2 of suspension bracket 1 by suspension hook 3, and sieve groove 14 is suspended in the coating bath 15, and coating bath 15 is fixed with suspension bracket 1 bottom, hang positive plate 17 in the coating bath 15, suspension bracket 1, machine sieve 5, vibratory screening apparatus, coating bath 15 adopt the plastics manufacturing.The part that the light decorations are handled well is poured in the sieve groove 14 of vibratory screening apparatus, connect power supply, choosing is the vibrational frequency of good vibratory screening apparatus then, ternary vibrating motor 6 begins to drive vibratory screening apparatus and does ternary vibration, and plating piece is done rotatablely moving at a slow speed in sieve groove 15, owing to sieve 15 ends of groove volution boss 20 is arranged, plating piece is also made tumbling motion, even sheet, tiny, irregular part also can't adhesions like this, the part that above-mentioned barrel plating can not be plated also can be realized electroplating, and the plating quality height.Turn off power supply after having plated, pull down vibratory screening apparatus and pour out part and get final product.
