Description
Technical field
The utility model relates to sand equipment on a kind of high speed compound electroplating diamond wire saw.
Background technology
Electroplating diamond wire saw utilizes electroplating technology to consolidate on the tinsel of high strength diadust knot as a kind of instrument of cutting.
At present, the field of electroplating diamond wire saw application has:
1, field of solar energy: the evolution of silicon single crystal, polysilicon and section;
2, LED field: sapphire evolution and section:
3, other field: the cutting of the expensive hard non-metallic material such as retentive material, pottery, crystal glass, jewel, jade.
The cutting advantage of use electroplating diamond wire saw is:
1, more durable than the diamond fretsaw of resin-bonded;
2, higher than the dissociate efficiency of cutting of mortar, and environmental pollution is little.
The present situation of Domestic Plating diamond fretsaw:
Domestic current silicon single crystal, polysilicon and sapphire adopt the free cutting of stainless steel wire mortar mostly; Because cutting speed in feet per minute is slow, waste mortar contaminate environment, has the trend be progressively eliminated; There is sub-fraction producer also at the diamond fretsaw adopting resin-bonded, because its durability is poorer than electroplating diamond wire saw, so existing a lot of producer progressively adopts electroplating diamond wire saw.
Although 3, electroplated diamond line of cut has many good qualities, in industrialization large-scale production process quality product or production efficiency be difficult to balance and control, current domestic on sale or use diamond fretsaw electroplating device, the upper sand form of core has several as follows:
A. sand buring method: tinsel is imbedded in the diadust being immersed in watt solution, by direct current, diadust is adsorbed on tinsel surface, reach the object of sand; The method has static sand buring method and uniform motion sand buring method two kinds of modes, and diadust is in static in the process, and tinsel is static or translational motion.
B. suspend upper sand method: by charged tinsel by dense containing diadust and with in the electroplate liquid stirred, touch diadust and reach Grains method; The method divides level, vertical, tilting three kinds by cabling form; The method divides heart yearn directly to walk by wiring configuration to be wound around two kinds back and forth with heart yearn; In suspension, the topmost feature of sand method is: (1) diadust is stirred by machinery or air and be suspended in electroplate liquid; (2) diadust used is nickel plating diadust; (3) upper sand electroplating power supply is all adopt direct supply substantially.
Although there is indivedual producer also can produce, production efficiency also has breakthrough, but because the system design of equipment and structure design unreasonable, all there is following shortcoming in varying degrees:
1, the configuration of upper sand electroplating power supply is single, or only adopts direct current electrode position power supply, or only adopts pulse plating power, cause wire when upper sand otherwise speed slow, or too fast and cause sand insecure.
Only the shortcoming of employing direct current electrode position power supply is: upper sand amount is extremely low, especially in high speed electrodeposition process, more cannot go up sand.The shortcoming of pulse plating power is only adopted to be: the firmness of upper sand is very low, by easily producing big area drop after reverse wheel conveying, and form the situation of the monolateral upper sand of wire, and in this area, also there is no a kind of technical scheme that can realize direct current electrode position and pulse plating being combined to solve above-mentioned upper sand problem.
2, production efficiency is low.Due to the characteristic of diadust, low current and low voltage generally can only be taked during upper sand to electroplate, the bonding force of later diamond and steel wire very little, electroplating time can only be extended and add its bonding force of jail, otherwise with conductive casters or when asking line to take turns to contact, diadust can be caused to come off, make sand failure.
3, upper sand lack of homogeneity.Sand buring method easily causes diadust to superpose accumulation; Although sand method can not form diadust superposition accumulation in suspension, can cause coming off with the diadust of wire contact surface when conductive casters or holder line wheel and form many few problems on one side.
4, the diadust amount that need retain of coating bath is large.As wire just must be embedded in wherein with a large amount of diadusts by sand buring method; And the upper sand rule that suspends require whole effectively on sand launder electroplate liquid in maintain enough diadust concentration, to increase the probability contacted with wire, and ensure the type of abrasive grain coating on wire.
5, upper sand uniformity coefficient and density can not control in real time.Electroplated diamond line of cut requires that in industrialization use procedure a few myriametre to tens myriametre can not break usually, and cut micro mist on different material requirements wires evenly outside, also has the coupling that the distribution density of micro mist and granularity etc. are different, and On line inspection and controlling functions are not had for domestic electroplating diamond wire saw production unit on sale or in using, so have no idea in process of production to distribution consistency degree and distribution density implementation effectively adjustment and the control of micro mist.
6, plating solution circulation is relatively slow, cause the nickel ion around wire can not supplement in time in concentration reduction process, and the hydrogen produced is attached to the absorption that wire surface hinders micro mist, make the distribution density of the micro mist after sand on wire wayward inadequate with firmness, and easily come off.
