The invention has simple production and low cost, with long service life.

Description

The grinding edge of improvement

Technical field

The present invention relates to a kind of grinding edge of improvement, is the structural improvement to grinding edge instrument blade part.

Background technology

The generation type of general diamond saw all is to utilize the softer sheet metal of a circle by mechanically rolling the outer fringe surface of abrasive grains with the annular copper plate body to be combined by mechanically rolling or through behind the high temperature again.This structure has cutting effect preferably, but this diamond saw is to utilize copper material or softer sheet metal made, and the intensity of copper material is not good only when carrying out high-speed cutting, gross distortion even damage to take place very easily with cutting at a slow speed.

Shown in Fig. 1 and Figure 1A, be respectively known by electroplating the diamond saw that forms in conjunction with the abrasive grains mode and the schematic perspective view of diamond drilling pipe, utilize blade part 10a, the 11a of circle or tubular metal material formation, pass through plating mode, electrodeposited coating is thickened abrasive grains is wrapped on blade part 10a, the 11a, and form diamond saw 10 and diamond drilling pipe 11; But this blade part 10a, 11a only wrap one deck abrasive grains by the appearance plating and carry out grinding and cutting, and very easily wearing and tearing are so the life-span of this cutting blade instrument is not long.

And for example Figure 2 shows that the diamond saw schematic perspective view of known nip drum formula in conjunction with abrasive grains, outer rim at a circular metal plate offers a plurality of tilted slotted hole 12a for inserting abrasive grains, the superimposed one by one mutually again while is with roller 13 roll extrusion outer rim places, the closed clamping abrasive grains of compressing tilted slotted hole 12a forms diamond saw 12; The diamond saw 12 of this structure was used in the cutting of precious stone before 1970, but the same not long defective in service life that has cutting.

For improving the defective of above-mentioned cutting blade instrument, develop a kind of diamond saw 14 of diamond metal sintering formula, as shown in Figure 3, by various metal dusts are mixed mutually with abrasive grains, and place a special mould, form a diamond wheel piece 14a with high temperature (650 ℃～1500 ℃) and high pressure mode, then, again each diamond wheel piece 14a is welded in a circular steel disc 14b outer rim place that is provided with axis hole and forms a diamond saw 14; But the diamond saw 14 of above-mentioned diamond metal sintering formula, need utilize the abrasive grains and the various metal dust of higher cost to make, when abrasive grains mixes mutually with metal dust, cause staff's cutaneous lesions easily, and, the peripheral equipment of making this diamond saw is all very expensive, power consumption greatly, also form air pollution easily, manufacturing process is also more loaded down with trivial details, causes manufacturing cost high, and the unit price of finished product is not striking, compare unit price with the diamond saw made from mechanically rolling formula or generally plating formula and exceed more than the several times, be difficult to meet the demand that every profession and trade reduces cost.Moreover as shown in Figure 3, though with diamond saw 14 bodies of diamond metal sintering formula indeformable advantage is arranged, its cutting effect slightly is inferior to the made copper material diamond saw of mechanically rolling formula.

So as can be known, the made diamond saw low cost of manufacture of mechanically rolling formula and plating formula, cutting effect be good, it is simple and easy to make, but undercapacity; And the diamond saw 14 of diamond metal sintering formula, because utilize steel to be main body, so its intensity is good indeformable, but cutting effect is slightly inferior, manufacturing cost is high.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of grinding edge of improvement, can reduce manufacturing cost, simplification manufacturing process, the sharpness of promoting diamond saw, raising cutting effect, increase service life.

In order to realize above-mentioned purpose of the present invention, a kind of grinding edge of improvement is provided, it comprises the blade part body that is made of metal, wherein, form a plurality of equidistant openings on the working face of described blade part body, in described opening, abrasive grains is set, described abrasive grains is fixed in the described opening form blade part, described blade part concave-convex surface by the metal of opening both sides is oppressed.

Described blade part body is a kind of in circular metal plate, metal tube body or the strip sheet metal that is provided with axis hole.

Described abrasive grains is a diamond grains.

Also have the abrasive grains layer that forms by electroplating at described blade part, described abrasive grains layer is filled the gap between described opening and the described abrasive grains, and covers described opening and described abrasive grains, makes the concavo-convex smooth of described blade part.

The specific embodiment

The present invention is a kind of grinding edge of improvement; described grinding edge is made by metal material; can be the known circular metal plate that is provided with axis hole; metal tube body or strip sheet metal (not having diagram); as Fig. 4; shown in Figure 5; described grinding edge comprises that one is provided with the circular metal plate 20 of axis hole or the blade part body that tubular bodies 30 forms; on the working face of described blade part body, offer a plurality of equidistant opening 20a; 30a; at described equidistant opening 20a; insert abrasive grains 40 among the 30a; described abrasive grains 40 can be diamond grains or other particle that is used to grind; wherein said opening 20a; the 30a width is slightly wide or be equal to the diameter of abrasive grains 40; insert each opening 20a at abrasive grains 40; after the 30a place; use mould to oppress each opening 20a simultaneously in two directions; the metal covering of 30a both sides; as Fig. 6; shown in Figure 8; this opening 20a; the metal covering of 30a both sides is subjected to mould compressing distortion also as shown in Figure 6A to each opening 20a; the 30a prescription coats abrasive grains 40 to extruding and forms blade part 201; 301; from Fig. 6; can see among Fig. 8 and Fig. 6 A; described blade part 201; 301 concave-convex surface; at blade part 201; 301 surface; as Fig. 7; Fig. 7 A and shown in Figure 9; electroplate one deck abrasive grains layer 401; so; promptly constitute one indeformable; long and the high blade part 201 of grinding and cutting power of life-span; 301; wherein; blade part 201; 301 plating abrasive grains layer 401 and each opening 20a; the abrasive grains 40 that the 30a bag is solid forms the diamond saw 2 that the life-span is long and can carry out fly-cutting; drilling pipe 3.

Wherein, the thickness of the plating abrasive grains layer 401 of blade part 201,301 can be according to different purposes increases and decreases, the plated metal of electrodeposited coating can be filled up the space between the abrasive grains of fixing in opening 20a, 30a and the opening 40, make the concavo-convex opposed flattened of described blade part, promote the fastness of abrasive grains at blade part 201,301 places.

The above is preferred embodiment of the present invention, as the change of doing according to conception of the present invention, must belong within protection scope of the present invention.
