Abstract
The invention relates to a sand feeding method for a diamond wire saw. The method comprises the following steps of: (1) preparing a diamond electroplating solution, wherein each litre of the electroplating solution comprises 10-20g of diamond, 100-240g of NiSO4, 40-100g of NiCl2, 10-50g of CoSO4 and 40-80g of H2BO3; (2) adding the electroplating solution to a sand feeding tower, wherein the sand feeding tower is in the shape of a column or polygon and is arranged vertically, and 2 to 8 Ni anodes are uniformly arranged on the inner wall of the sand feeding tower; and (3) making a bare metal wire penetrate into the bottom of the sand feeding tower and out of the tower top at a speed of 2-8 m/min; by adopting the bare metal wire as the cathode and Ni as the anode during the penetration of the bare metal wire, applying DC (Direct current) and plating diamond on the bare metal wire. The diamonds on the diamond wire saw prepared by the invention are uniformly distributed and are not accumulated.
Description
Technical field
The present invention relates to a kind of last sand method of diamond wire saw, soon diamond is fixed on the method on the metal bare wire.
Background technology
Along with the cutting of photovoltaic with silicon materials and LED sapphire substrate needs, the usage quantity of diamond fretsaw is increased substantially, the diamond fretsaw domestic market almost completely is that an external saw manufacturers occupies at present, and domestic enterprise has many gordian techniquies also to break through.
The conventional manufacture method of diamond wire saw is to emit bare wire from an actinobacillus wheel, passes through oil removing, rust cleaning, nickel preplating, goes up operations such as sand, nickel plating thickening, cleaning, oven dry, wire coiler take-up.Whole line is mobile in the horizontal direction, particularly go up the sand operation and often adopt the sand method of burying, being about to bare wire passes from " a pile " diamond, in the process of passing, effect by electric current is fixed on the part diamond on the bare wire, thereby finish the sand process, thisly bury that sand has following drawback on the sand method:
One: because line is constantly proal in sand, diamond is after being plated on the line, because coating is very thin, coating is very little to durability of diamond, so when passing " sand heap ", the diamond overwhelming majority that is fixed is blocked, and makes the quantity of sand uncontrollable, what differ, and are extremely inhomogeneous.
Its two: because line navigates within Sha Duizhong, make to produce friction between line and diamond, make the nickel dam that plates in advance be easy to be rubbed off, diamond and later nickel thickening layer and the bonding force on line surface are reduced, cause adamantine improper coming off.
Its three: because line is embedded in Sha Duizhong, sand heap is fully immersed in again in the plating bath, makes the suffered pressure difference of upper and lower surface of line, and the suffered frictional force of the sand on surface is also different, must make the diamond particles number of the upper and lower surface of line that very big difference is arranged, make line in cutting, occur deviation phenomenon easily.
Summary of the invention
The objective of the invention is to overcome the defective that above-mentioned prior art exists, a kind of last sand method of brand-new diamond wire saw is provided, diamond can be fixed on the metal bare wire equably.
The present invention includes following steps:
1) preparation diamond electroplating liquid comprises in every liter of electroplate liquid: 10-20 gram diamonds, 100-240 gram NiSO
4, 40-100 restrains NiCl
2, 10-50 restrains CoSO
4, 40-80 the gram H
2BO
3
Above-mentioned solution is mixed by single nickel salt, nickelous chloride, rose vitriol, boric acid, water after stir formulatedly, and diamond is suspended state in electroplate liquid.
2) electroplate liquid is placed the sand tower, the cylindrical or Polygons of sand tower on this, the vertical placement evenly placed 2-8 and propped up the Ni anode on its inwall;
3) metal Naked line is penetrated with the speed of 2-8m/min at the bottom of last sand Tata, pass from cat head; The metal bare wire is walked in the process, is negative pole with the metal bare wire, and Ni is an anode, applies direct current, and diamond is plated on the metal bare wire.
Because the metal bare wire is as negative electrode in electroplating process, therefore for it is consistent to the anodic distance, improve the homogeneity that diamond distributes on the metal bare wire, so the metal bare wire is that the medullary ray of sand tower on the edge is walked when walking in last sand tower.
Go up and in electroplate liquid, contain acid, therefore go up the sand tower and preferably adopt material to make with good heatproof erosion resistance, in high molecular polymerization materials such as PP, PE, PC, PVC, the preferably commonly used and high PVC material of sexual valence.
The diameter that the above-mentioned internal diameter of going up the sand tower is 50-120mm, metal bare wire is that 0.1-0.4mm, the electric current when electroplating are 1-5A.
Because last sand tower is vertically disposed, therefore the metal bare wire from the sand tower bottom to the process that the top is walked, electroplate liquid has seepage, therefore in electroplating process, need the electroplate liquid that will spill to cause the reservoir of the electroplate liquid of establishing in addition, go up the interior electroplate liquid of sand tower simultaneously and will constantly replenish with pipe.
For security deposit's hard rock is suspended in the electroplate liquid, its particle diameter is controlled between the 10-40 μ.
Adamantine distributing very evenly on the diamond wire saw of employing the present invention preparation, with 200 times of CCD microscopic examinations, diamond does not have packing phenomenon.With silk saw fixing after, rotate four times, the diamond particles number on each direction is counted, the data ratio on each direction (data little be molecule) is all greater than 0.70.Recording a silk saw cylindricity with electronic microcalliper is 0.03, these all be existing bury the sand method can't realize.
