Abstract
The utility model relates to an electroplating diamond grinding tool which is made by electrically plating a layer of metal core body inlaid with diamonds onto a foil-shaped metal basal body. For the convenience of being cut into a required shape, a cutting line which is not plated with the metal core body or the diamonds is arranged on a grinding sheet. The grinding sheet is soft and is easy to be deformed. The grinding sheet is as soft as a piece of sand paper, so the grinding sheet is convenient to be used for grinding a workpiece with a curved surface like a sparking plug. Compared with the common sand paper, the embedding strength of the diamonds on a sheet metal is higher than the bonding strength of the emery on the sand paper, and the strength of the sheet metal which is used as the basal body is higher than paper or cloth, so the electroplating diamond grinding tool is not easy to have overall destruction and the service life of the electroplating diamond grinding tool is longer than that of the common sand paper (or cloth). The utility model has the advantages of portability.
Description
The utility model relates to hand grinding tool, particularly a kind of electroplated diamond grinding tool.
Normally used sand paper (cloth) is to adhere to sand grains or diamond dust on paper or cloth, as abrasive material or polishing material.This sand paper (cloth) is because of the threshing easily of cohesive force difference, and backing material intensity is low, breaks easily, forms whole the damage.In addition, the intensity of diamond dust is also not high enough, far below diamond, thereby causes quick abrasion, short-life shortcoming.In maintenance during sparking plug for internal combustion engine, in order to grind off the carbon deposit on surface, or when grinding work piece, bag grinder part all need expend a large amount of sand paper (cloth), and is both uneconomical, also inconvenient.Diamond saw is also arranged at present, and diamond file etc., its surperficial diamond coating are to electroplate one deck impregnated with diamond carcass metal and make on metallic matrix.Though hardness height, durable because of not having the flexibility of sand paper, is unsuitable for reconditioning spark plug one class parts or does the instrument use that bag grinds the curved surface shaped workpiece.Existing electroplated diamond grinding tool all is a rigid matrix, lacks the flexibility as sand paper.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of flexible electroplated diamond grinding tool of similar sand paper (cloth) that has is provided.
The purpose of this utility model realizes in the following way: electroplate the diamond impregnated carcass metal of one deck on paper tinsel (sheet) shape metallic matrix.Need emphasize that the metallic matrix here is paper tinsel (sheet) shape.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Fig. 1 is the structural representation of electroplated diamond abrasive sheet.
Fig. 2 is the electric degree diamond grinding sheet that shearing line is set.
Fig. 3 is the A-A cutaway view of Fig. 2.
Referring to Fig. 1, paper tinsel shape sheet metal 1 is a matrix, and its electroplating surface one deck (or positive and negative respectively plates one deck) carcass metal 2, carcass metal plate a large amount of diamond dusts 3 as abrasive particle equably in deposition process.For ease of abrasive sheet is cut into required form, shearing line 4 is set on abrasive sheet, see Fig. 2, Fig. 3, not plating carcass and diamond on the shearing line 4.Brush on shearing line with organic coating (as resin, lacquer class etc.) before plating, the shearing line width is generally 1～2mm for this reason.Owing to the obstruct of organic substance, can avoid carcass metal and adamantine deposition in the electroplating process.Owing to do not have carcass metal and diamond on the shearing line, therefore, when the very little workpiece of grinding radius of curvature, abrasive sheet is easier to bending, can avoid the abrasive sheet overbending simultaneously and causes carcass metal and adamantine damage.
The diamond wear proof performance is good, and the effect one of electroplated diamond carcass is to fix, plate diamond, and the 2nd, make the diamond in the carcass go out sword in good time, in right amount.Therefore, the hardness of carcass metal should remain between HRc25～35, to guarantee good operating characteristic.
Electroplated diamond has been the technology of a maturation on metallic matrix, there is not any technical difficulty in electroplated diamond yet on the paillon foil metal, the those of ordinary skill of electroplating industry can both be implemented, but this technology of the human type diamond milling tools of laminating is not arranged so far as yet.
This electroplated diamond thin slice softness, easily deformable as sand paper (cloth) be convenient to polish spark plug and curved surface shaped workpiece, can extensively replace the sand paper, the emery cloth that adopt at present.Compare with common sand paper (cloth), diamond substantially exceeds the adhesion strength of diamond dust on sand paper in the intensity that plates on the sheet metal, so diamond is difficult for threshing.And sheet metal also is higher than paper or cloth as the intensity of matrix, is difficult for producing whole the damage, and simultaneously, adamantine hardness is higher than diamond dust, and antiwear property is strong.Because these characteristics, the life-span of electroplated diamond thin slice is far longer than common sand paper (cloth).Under same condition of work, as the polishing sparking plug for internal combustion engine, a small pieces electroplated diamond paillon foil can use the several years, be equivalent to save hundreds of sand paper, and its price only is equivalent to the price of several sand paper.Because adamantine price is directly proportional with granular size, the following fine diamond powder of required 200 orders of diamond disk is very cheap, and the source of goods is also very sufficient.The electroplated diamond thin slice is mechanic, driver and internal combustion engine mechanic's a useful tool because of durable in use, easy to carry, low price.
Claims (2)
1, a kind of electroplated diamond grinding tool is electroplate with the carcass metal 2 of one deck impregnated with diamond 3 on metallic matrix 1, it is characterized in that said metallic matrix 1 is a paper tinsel shape metal.
2, grinding tool as claimed in claim 1 is characterized in that said matrix 1 is provided with not plating carcass and adamantine shearing line 4.
