Abstract
The present invention relates to a kind of manufacturing process of diamond saw blade, particularly be used for processing the manufacturing process of the diamond saw blade of building stones, joint-cutting cement pavement, stripping and slicing cement products.It is at normal temperatures, adopts electro-plating method to manufacture the diamond cast sheet, and in this way impregnated welding-on is made diamond saw blade on saw bit matrix.Utilize this technology to make diamond saw blade, can improve saw blade stock-removing efficiency, work-ing life and and blade between bonding strength, thereby make low-grade man-made diamond obtain development and use.
Description
The present invention relates to a kind of manufacturing process of diamond saw blade, especially for the manufacturing process of the diamond saw blade of building stones processing, cement pavement joint-cutting, cement products stripping and slicing.
Diamond saw blade is a kind of cutting tool, because its special cutting object, the diamond saw blade manufacturing process has been proposed certain requirement, not only requirement can keep original intensity of diamond and hardness, also requiring has stronger bonding strength between cutting teeth and the matrix, with the work-ing life and the stock-removing efficiency of security deposit's diamond saw blade.Making at present the method that diamond saw blade adopted has two kinds, and the one: directly diamond is crimped on the matrix with pressure sintering and makes; The 2nd: with pressure sintering bort(z) is made impregnated (being cutting teeth) earlier, then, adopt the ratio-frequency welding connection, diamond cast sheet welding-on on matrix, is formed cutting teeth.Yet the hot pressing means that adopted in two kinds of methods all will make diamond stand high temperature about 1000 ℃, and under such high temperature, diamond greying easily takes place and produces heat crack, thereby has reduced original intensity of diamond and hardness.Adopt hight frequency welding, bonding strength is not high, thereby makes that the working durability short, and service efficiency is low.
The purpose of this invention is to provide and a kind ofly can keep original intensity of diamond and hardness, the manufacturing process of the diamond saw blade that the bonding strength between diamond cast sheet and the matrix is high.
The object of the present invention is achieved like this, under normal temperature (20～30 ℃), adopts electric plating method, with single nickel salt (и iSO
47H
2O), rose vitriol (COSO
47H
2O), boric acid (H
3BO
3), in the electroplate liquid of sodium-chlor (и aCl) preparation,, foldedly make impregnated with nickel-cobalt alloy plating parcel bortz powder granulosa, the same electric plating method of using, in this electroplate liquid, utilize the effect of the power between the atomic bond, with impregnated of electroplated diamond securely welding-on on matrix.The adding of cobalt atom in the electroplate liquid makes coating atomic structure generation lattice distortion, thereby coating hardness is improved.
Adopt this method to make diamond saw blade, because making temperature reduces greatly, avoided diamond to damage because of being heated, improved bonding strength, thereby also improved the quality of diamond saw blade greatly, with pressure sintering, hot pressing is compared with the ratio-frequency welding connection, the saw blade of Zhi Zaoing improves 0.2～0.25 times work-ing life in this way, and cutting speed is wanted fast 0.25～0.33 times.Simultaneously because when electroplating, diamond can self-orientation, is about to the difficultest hard cutting edge nature itself towards the object that is cut, and has so just given full play to adamantine cutting effect.Owing to above reason, adopt this method, can make low-grade man-made diamond, obtain development and use, thereby reduced production cost.In addition, it is simple that the present invention also has technology, advantage with short production cycle.
For clearer reproduction manufacturing technique for electroplated diamond saw blade of the present invention, processing sequence of the present invention and concrete operations are described further below in conjunction with accompanying drawing.

Fig. 2 for Figure 1A to the part overlook enlarged view.
Fig. 3 is for electroplating wiring diagram.
Fig. 4 is the sectional drawing of the circular diamond saw blade of the knuckle-tooth made.
Fig. 5 for Fig. 4 B to the part overlook enlarged view.
With reference to Fig. 3, wherein (1)-rectifying device, (2)-transfer switch, (3)-charging set, (4)-store battery, (5)-DC ammeter, (6)-slide bar varistor, (7)-nickel anode, (8)-plating bath, (9)-quilt are plated cutter (negative electrode), (10)-coating bath.
(1) plating solution formula and preparation (tyre body hardness is the nickel cobalt (alloy) about HRC30).
Single nickel salt 280～300 grams per liters
Rose vitriol 15～25 grams per liters
Boric acid 38 grams per liters
Sodium-chlor 18 grams per liters
Above medicine adopts the above purity of chemical pure, uses the distilled water heating for dissolving respectively, mixes then, filters, and it is stand-by to adjust acidity.
(2) saw bit matrix and impregnated manufacturing
Saw blade size and shape need be determined according to customer requirements.
As the circular cast-cutting saw slice of φ 400 * 7 * φ 50 sipes knuckle-tooth cement pavements.Matrix adopting 65Mn steel plate.The thermal treatment post-treatment becomes Fig. 1 shape.Wipe the burr wedge angle with file, emery cloth.
Can make different shape for impregnated.Concrete making method is: according to impregnated thickness, select the plastic plate of respective thickness, extrude the identical through hole of countless and impregnated plate shape on plastic plate.Plastic plate is close on stainless steel plate or the iron plate, and the part that leaks outside of the stainless steel plate beyond the insulated vias connects lead, washes away totally and can put into plating tank.(4), (five) are seen in electroplating standard and operation.
(3) inlay and plate pre-treatment.
Impregnated is embedded in the saw bit matrix with the transition fit form.Impregnated as required can with matrix with thick, smoothly join, impregnated both sides are given prominence to outside matrix slightly.
The matrix that edge the is good lead of burn-oning is cleaned once with acetone, insulate with acid and alkali-resistance insulation compound or zylonite and does not plate part.Carry out the hcl corrosion rust cleaning after insulant parches, concentration of hydrochloric acid about 30%, soak at room temperature were immersed in and prepare to carry out electrochemical degreasing in the warm water after 30 seconds.Oil removing solution composition: sodium hydroxide (и aOH) 17 grams per liters, yellow soda ash (и a
2CO
3) 38 grams per liters, tertiary sodium phosphate (и apO
412H
2O) 15 grams per liters, water glass (и a

39H
2O) 9 grams per liters, processing specification: 30 ℃ of temperature, current density 10 peace/decimetres
2, first negative electrode oil removing 2.5 minutes, back anode oil removing 1 minute, another is the nickel plate very.After disposing, use warm water soaking, prepare anodizing.Anodizing solution is the 40%(volume ratio) sulfuric acid, 1 minute time, current density 35 peace/decimetres
2, anode is a stereotype.After the anodizing, use warm water washing as early as possible, press Fig. 2 put in circuit, the charged plating tank of putting into.
(4) electroplating standard
Temperature: 20 ℃-30 ℃, current density: 1 peace/decimetre
2, acidity: pH4-4.5.
(5) electroplating operations
After substrate is gone into groove, earlier with 3 peace/decimetres
2Current density impacted 2 minutes, with the empty plating of normal standard 1 hour, empty plating finished, and with straight shape leather point suction pipe the bort(z) suction is sprinkling upon on the land endless belt of matrix periphery then.After diamond spreads; Unload sand (bort(z)) every for some time turn-over, make by the plating surface and evenly be stained with one deck diamond particles.Spread and unload diamond time and adjacent twice stucco timed interval, can determine by the diamond concentration of customer requirements.Unload sand time lag and the shortening of twice stucco time, all can improve diamond concentration, generally the former is ten minutes, and the latter is 24 hours, and such time can make diamond concentration reach 75%.
After saw blade cutter tooth thickness reaches requirement, can go out groove.Go out the saw blade slot warm water washing, remove insulant, can carry out dehydrogenation and handle treatment process: 160 ℃ are incubated three hours in baking oven.Dehydrogenation finish, scalp dross product.
