Abstract
The present invention relates to a new method for producing a diamond saw blade and a band saw blade through heat pressing and low temperature electroplating. The present invention is characterized in that a diamond impregnated sheet 1 is firstly produced by adopting a heat pressing method, and the diamond impregnated sheet 1 is welded onto a basal body 2 of the diamond saw blade and the band saw blade by adopting a low temperature electroplating method. The present invention has the advantages of uniform distribution of diamonds in a cutting edge, good edge outlet effect, high strength and wear resistance of the diamonds, no damage, firm welding between the diamond impregnated sheet 1 and the basal body 2, short production period, etc. Compared with the prior art which uses a low temperature electroplating method to produce a diamond saw blade and a band saw blade, the present invention has the advantages that the efficiency can be improved by about 20% and the service life can be extended by about 20%. The diamond saw blade and the band saw blade which are produced by the present invention are ideal tools for processing stones and cutting joints of pavements.
Description
The present invention is the diamond saw blade of cutting building stones and the manufacture method of bands for band.
At present, the method for manufacturing diamond saw blade has following four kinds: one, directly diamond and other metal-powder are crimped on the matrix with pressure sintering; Two, earlier diamond and other metal-powder are pressed into the diamond cast sheet, adopt the ratio-frequency welding connection then with pressure sintering, with diamond cast sheet welding-on on matrix; Three, adopt the cold galvanising method directly diamond and alloy carcass to be electroplated onto on the matrix; Four, adopt earlier cold galvanising method processing diamond cast sheet, still adopt then the cold galvanising method with diamond cast sheet welding-on to matrix, as CN86107053A.
The diamond saw blade that above-mentioned pressure sintering and hot pressing one ratio-frequency welding connection are produced, having diamond, to be evenly distributed, to go out sword in cutting edge good, advantage such as with short production cycle, but hot pressing temperature is about 1000 ℃, the diamond subject to damage, influence its wear resistance, and the diamond cast sheet of hight frequency welding comes off easily.The cold galvanising method is produced diamond saw blade, can protect adamantine intensity to greatest extent, and diamond cast sheet and matrix welding-on are firm, but that diamond distributes in cutting edge is difficult even, and the production cycle is long.
The object of the present invention is to provide a kind of hot pressing one electroplating new method of producing diamond saw blade and bands for band, to overcome the deficiency of prior art, realize with short production cycle, diamond is evenly distributed in cutting edge, it is effective to go out sword, adamantine intensity is injury-free, diamond cast sheet and the firm ideal effect of matrix welding-on.
Feature of the present invention is, adopts pressure sintering to produce diamond cast sheet 1 earlier, adopt then the cold galvanising method with diamond cast sheet 1 welding-on to the matrix 2 of diamond saw blade and bands for band, make diamond saw blade and band-saw diamond bar.
The production method of diamond cast sheet 1 is, select the diamond and the definite abundant mixing of metal-powder material of suitable granularity and grade for use after, compacting sintering in the graphite jig of packing into, temperature is controlled in 700～750 ℃, pressure-controlling is in 12～15MPa.It selects materials and fills a prescription as follows:
Copper powder 30～50%
Nickel powder 15～20%
Cobalt powder 20～25%
Zinc powder 5～6%
Glass putty 4～5%
Wolfram varbide 5～10%
Diamond (concentration) 50～75%
Other is 1～2% years old
The granularity of above-mentioned man-made diamond and metal-powder is all below 200 orders.
Prescription one:
Single nickel salt 260g/l
Manganous sulfate 8g/l
Sal epsom 10～20g/l
Boric acid 35～40g/l

Above-mentioned two kinds of used medicines of plating solution formula are all selected chemical pure for use.The industrial pure hydrochloric acid of the optional usefulness of iron protochloride in the prescription two adds the iron powder preparation, uses after treatment, and its cost is lower.
Main processes of the present invention is, adopt pressure sintering to produce diamond cast sheet 1 earlier, on diamond saw blade and band-saw diamond bar matrix 2, process corresponding embedding groove simultaneously, then diamond cast sheet 1 is pressed in the embedding groove of matrix 2, adopt any one electroplate liquid in two kinds of plating solution formulas provided by the invention to electroplate welding-on at last, add a small amount of bortz powder during plating, its purpose is to eliminate the internal stress that is produced in the welding-on process, guarantee the firm welding degree of diamond cast sheet 1 and matrix 2, increase the wear resistance of coating simultaneously.

Fig. 2 is the schematic perspective view of two circular arc sheet diamond cast sheets 1;
Fig. 3 is the diamond saw blade vertical view;
Fig. 4 is Fig. 3 A-A sectional view;
Fig. 5 is band-saw diamond bar (part) vertical view;
Fig. 6 is the B-B sectional view of Fig. 5.
The diamond cast sheet 1 that the present invention produces, the tyre-e/or performance adjustable range is the adjustable extent of galvanoplastic head and shoulders above, thereby its applicability is wide. The carcass metal has maceration to diamond under Applicable temperature of the present invention, it is firm to plate diamond, and diamond exposure is good. The hot pressing process is carried out in graphite jig, and graphite produces incomplete oxidation, generates CO gas, and the carcass metal dust is had reduction, and diamond is had certain protective effect, thereby the basic not damaged of diamond, has guaranteed intensity and wearability that diamond is intrinsic.
The cold galvanising method welding-on technology that the present invention adopts, diamond cast sheet 1 is firm, with short production cycle with matrix 2 combinations, and the required cost of raw material is lower in the plating solution formula.
Therefore, diamond saw blade and diamond band saw blade that the present invention produces, compare with diamond band saw blade with the diamond saw blade of producing by galvanoplastic in the prior art, timeliness can improve about 20%, also can improve about 20% service life, be the ideal tools of cutting building stones, concrete road surface etc., can be widely used in stone material processing, cement pavement joint-cutting, cement products stripping and slicing etc.
By two kinds of plating solution formulas provided by the invention, can also directly produce diamond saw blade and bands for band. Comprise directly on diamond saw blade and bands for band matrix electroplated diamond and carcass and produce the diamond cast sheet by galvanoplastic earlier, then still by galvanoplastic with diamond cast sheet welding-on to matrix.
