For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of last sand launder of making electroplating diamond wire saw; Comprise on the bottom that is provided with at interval of layering, circulation groove and circulation groove top sand launder on the sand launder and top; Be equipped with the leakage plate that has liquid-leaking nozzle bottom the sand launder on sand launder and the top on the bottom, the sand launder top is provided with the inlet opening that communicates with circulation groove through the liquid pipe on the top, is connected with chemical pumping on the liquid pipe; On the bottom on sand launder and the top sand launder both sides be equipped with conductive rollers, be equipped with the nickel plate on the bottom on sand launder and the top in the sand launder.
Be equipped with gauze above the sand launder bottom leakage plate on sand launder and the top on the said bottom.
Said nickel plate is arranged on the bottom both sides, inside of sand launder on the sand launder and top through the titanium reel.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises on the bottom that the top layering of circulation groove and circulation groove is provided with at interval sand launder on the sand launder and top; Be equipped with the leakage plate that has liquid-leaking nozzle on the bottom on sand launder and the top bottom the sand launder; The sand launder top is provided with the inlet opening that communicates with circulation groove through the liquid pipe on the top, is connected with chemical pumping on the liquid pipe; On the bottom on sand launder and the top sand launder both sides be equipped with conductive rollers, be equipped with the nickel plate on the bottom on sand launder and the top in the sand launder, simple and reasonable; Easy to manufacture; Need not to be provided with whipping appts in the plating bath, avoided the plating bath impact fixed to diadust of flowing, last sand efficient is high; The diamond fretsaw of producing by sand launder on this have micro powder granule be evenly distributed densification, cutting is sharp, cutting efficiency is high and the advantage of long service life.
2, above sand launder on the top, be provided with inlet opening; Can increase the touch opportunity of diadust and matrix metal line; Overcome the problem of the few and loose contact of micro mist and matrix metal line touch opportunity; Improve the density of last sand, can improve diamond fretsaw micro mist distributing homogeneity and cutting efficiency greatly.
3, utilize sand on the utility model, sand efficient is high on it, and last sand speed is fast, the micro powder granule densification that is evenly distributed, cut sharp, suitable large-scale production.

Embodiment
The last sand launder of manufacturing electroplating diamond wire saw as depicted in figs. 1 and 2; It comprises on the bottom that circulation groove 1 and circulation groove 1 top layering be provided with at interval sand launder 3 on the sand launder 2 and top; Sand launder 3 bottoms are equipped with the leakage plate 6 that has liquid-leaking nozzle on sand launder on the bottom 2 and top, on the bottom on sand launder 2 and the top leakage plate 6 tops of sand launder 3 bottoms be equipped with gauze 7.Above sand launder on the top 3, be provided with the inlet opening 5 that communicates with circulation groove 1 through liquid pipe 9, the inlet opening oral area is provided with gauze, and the shape of inlet opening 5 can be rectangle, and the medullary ray of length direction is over against the metal wire matrix 8 of below.Connect chemical pumping 10 on the liquid pipe 9; Chemical pumping 10 is used in the sand launder 3 on the plating bath of circulation groove 1 and the diadust pump to top in the lump; And can keep diadust to be in suspended state, and the controllable rotation speed of chemical pumping 10, be used for regulating the feed liquor amount and advance the sand amount.Sand launder 3 both sides external are equipped with the conductive rollers 4 of twining metal wire matrix 8 on sand launder on the bottom 2 and top; On the bottom on sand launder 2 and the top sand launder 3 inner both sides all be equipped with nickel plate 12 through titanium reel 11; Nickel plate 12 is positioned at the both sides of metal wire matrix 8, and nickel plate 12 is used for replenishing the loss of nickel ion in the plating bath.During use, titanium reel 11 is anodal through wire connecting power, and conductive rollers 4 is through the wire connecting power negative pole.
Gauze 7 is processed by oxytalan, and thickness is that 0.3～0.5mm, aperture are slightly larger than diadust particulate maximum particle diameter, can avoid the bulky diamond micro mist residual in a large number, slows down the diadust falling velocity simultaneously; If residual diadust is arranged, can chemical pumping 10 rotating speeds be transferred soon on the gauze 7, it is washed out.
Leakage plate 6 plays the effect of supporting gauze 7 for the PVC board making forms, and keeps the plating bath amount in the sand launder simultaneously.The liquid-leaking nozzle of arranging on the leakage plate 6, the related diadust of plating bath falls from liquid-leaking nozzle, and the length direction medullary ray of liquid-leaking nozzle faces metal wire matrix 8.
The utility model use is: chemical pumping 10 with the plating bath in the circulation groove 1 and diadust through in the sand launder 3 on liquid pipe 9 and inlet opening 5 pumps to the top; The diadust that is fallen by inlet opening 5 directly contacts, collides with metal wire matrix 8, and with the surface of nickel ion composite deposition to metal wire matrix 8; Not sedimentary diadust is accomplished in the same way and is gone up the sand operation along with plating bath once flow on the bottom in the sand launder 2 through gauze 7 and leakage plate 6; Diadust is along with plating bath flows into circulation groove 1 at last, and beginning is next to circulate.In said process, conductive rollers 4 keeps walking about synchronously (rotations) with metal wire matrix 8, when metal wire matrix 8 by the bottom on the sand launder 2 entering tops behind the sand launder 3, begin to change sand on the face, leave sand launder 3 on the top at last, thereby sand on accomplishing.
In last sand process, chemical pumping 10 slowly runs, and both can slow down diadust and fall to the impact of metal wire matrix 8, can guarantee again on the bottom that sand launder 3 has enough plating baths and diadust on the sand launder 2 and top; The walking speed of the rotating speed of conductive rollers 4 and metal wire matrix 8 keeps can guaranteeing metal wire matrix 8 tension stabilities synchronously, avoids both caused by relative motion frictions, moves smooth and easy; Metal wire matrix 8 is submerged in 3～5cm place under the plating bath liquid level, and inlet opening 5 exceeds liquid level 1cm, drops down onto on the metal wire matrix 8 from inlet opening 5 effusive diadusts, is accompanied by the deposition of nickel ion, realizes the fixed of diadust; Metal wire matrix 8 is walked around on the conductive rollers 4 entering tops sand launder 2 on sand launder 3 or the bottom, and rotates with speed, repeatedly walks around conductive rollers 4 and changes on the face sand on the sand and secondary to guarantee metal wire matrix 8, has guaranteed the homogeneity and the compactness of micro mist abrasive particle distribution.
The utility model is not limited to above-mentioned embodiment: the quantity of inlet opening 5 can be confirmed according to actual needs, directly contacts and the chance of colliding to guarantee diadust and metal wire matrix 8; In order to reduce the loss of plating bath, also can install guide roller additional with inside bottom at sand launder 3 oral areas on sand launder on the bottom 2 and the top, get on the bottom mode of sand launder 3 on the sand launder 2 and top to replace metal wire matrix 8 through aperture.
