Description

The reinforced diamond disc of a kind of matrix

Technical field

The utility model relates to cutting-tool engineering field, is specifically related to the reinforced diamond disc of a kind of matrix.

Background technology

Diamond disc is the cutter that in diamond class instrument, consumption is maximum, accounts for more than 95% of diamond cutter material consumption total amount.In recent years, China has carried out large quantity research in optimization diamond disc joint block formula, and the sawing performance of diamond disc is significantly improved, and cutter head cost reduces greatly, improves the competitiveness in domestic saw blade at home and abroad market.

Along with the range of application of diamond disc is increasingly extensive, processing object is day by day complicated, at present to saw blade apart from general wearability, outside the performance requirements such as sharpness, also machined material is adapted to (as various marble to it, granite, armored concrete, bituminous paving etc.), processing conditions (is cut as dry, wet and cut, sawing ultra thin plate, high precision plates etc.) and environmental requirement (as noise, blowdown etc.) ability propose requirements at the higher level, these all propose new challenge to the design and manufaction of diamond disc, improve saw blade performance only by optimization joint block formula to be nowhere near, also must obtain more progress and breakthrough improving in saw-blade structure.

In recent years, the various Novel saw blade matrix of domestic and international exploitation and use and broached-tooth design are (as saw bit matrix opens air-flow hole slot or edge damping material, form the sandwich interlayer tooth of sawtooth central concave abrasive, multiple serration, radial extension tooth, carbide alloy protects tooth etc.) to improving sawing friction and cooling condition, improve saw blade sharpness and cutting stationarity, prevent sawtooth from skidding, prevent flank wear, adapt to the processing of soft or hard composite material, avoid tooth, save cutter material, make full use of sawtooth material, reduce sawing noise etc. and serve important function, prove that improving saw bit matrix and broached-tooth design is one of important channel of improving sawing effect thus.But, at present on various matrix and broached-tooth design is stressed on saw blade, rigidity, distortion, stress distribution, friction, noise etc. impact also lack the theory analysis of the system of going deep into, the theoretical foundation thus proposing to improve matrix and broached-tooth design technical scheme is still insufficient.The domestic and international Study and appliance achievement improving saw bit matrix and broached-tooth design of review paper herein, analyze the feature of various broached-tooth design, productive value and existing problems, and propose research saw bit matrix and the theoretical question that relates to of broached-tooth design and technical prospect.

In sawing process, saw blade runs up, and saw bit matrix and talus glacier produce fretting wear.Because the gauge wear and side wear that save block are inconsistent, when saving block working lining and ruing out of, the friction of saw bit matrix and landwaste strengthens, cause " binding ", this will cause wearing and tearing and the distortion of saw bit matrix, and for this reason, we take to strengthen the measure that matrix can improve again rigidity of saw blade.

Utility model content

The purpose of this utility model is defect for prior art and deficiency, the reinforced diamond disc of matrix providing a kind of structure simple, reasonable in design, easy to use.

For achieving the above object, the technical solution adopted in the utility model is: it comprises matrix, joint block, tank, meltallizing layer, meltallizing layer drop border; The circumferential edge of described matrix is provided with joint block, and base circumferential limit and joint block are evenly distributed in some tanks communicated; The marginal surface place of described matrix is provided with meltallizing layer, and the surface of meltallizing layer and matrix forms irregular meltallizing layer drop border.

As preferably, described meltallizing layer adopts WC-Co hard alloy low temperature plasma spraying to be sprayed on matrix.

As preferably, the thickness of described meltallizing layer is 0.6 ~ 1.2mm.

After adopting said structure, the beneficial effect that the utility model produces is: the reinforced diamond disc of a kind of matrix described in the utility model, strengthen matrix, both flank wear can be prevented, can rigidity of saw blade be improved again, the utility model have structure simple, arrange rationally, the advantage such as cost of manufacture is low.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to as shown in Figure 1, this detailed description of the invention adopts following technical scheme: it comprises matrix 1, joint block 2, tank 3, meltallizing layer 4, meltallizing layer drop border 5; The circumferential edge of described matrix 1 is provided with joint block 2, and matrix 1 circumferential edge and joint block 2 are evenly distributed in some tanks 3 communicated; The marginal surface place of described matrix 1 is provided with meltallizing layer 4, and meltallizing layer 4 forms irregular meltallizing layer drop border 5 with the surface of matrix 1.

As preferably, described meltallizing layer 4 adopts WC-Co hard alloy low temperature plasma spraying to be sprayed on matrix 1.

As preferably, the thickness of described meltallizing layer 4 is 0.6 ~ 1.2mm.

After adopting said structure, the beneficial effect that this detailed description of the invention produces is the reinforced diamond disc of a kind of matrix described in this detailed description of the invention, strengthen matrix, both flank wear can be prevented, can rigidity of saw blade be improved again, this detailed description of the invention have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
