Abstract
The utility model relates to a cemented carbide circular saw blade, comprising cutter heads (1) and matrixes (2). The cutter heads (1) are composed of cemented carbide blocks and solders, wherein the cemented carbide blocks are of irregular shapes and are in irregular arrangement, corner angles at the tooth tip are clearly demarcated and edges are uniform. The matrixes (2), after machining, are brazed with the cutter head (1) and are provided with C-shaped laser cutting gaps (4) which are distributed in a uniform and circumferential manner. The matrixes (2) between every two adjacent groups of cutter heads (1) are equipped with expansion gas (3) inlayed with copper rivets. The beneficial effects of the utility model are that the defects of the prior art are solved and provided is a cemented carbide circular saw blade which is high in sharpness and in cutting output, rapid in heat radiation, easy in manufacturing process and low in economist cost, has the noise canceling effect and is applicable to the crushing and sawing of reinforced concretes, asphalt stones and other materials.
Description
Technical field
The utility model relates to a kind of sintered carbide circular saw, and particularly a kind of braze welding type sintered carbide circular saw can be widely used in the broken sawing of materials such as armored concrete, pitch stone.
Background technology
At present, be used for construction material, finishing, cast-cutting saw slices such as road repairing are more and more.In the prior art, diamond disc is used in the cutting of materials such as armored concrete, pitch stone always, and this type of saw blade is to utilize the adamantine high-speed grinding of granule to realize cutting.Though the machining accuracy height, cutting speed is slow, the cutting quick heating, and matrix is yielding, and has the manufacturing process complexity of saw blade, shortcomings such as production cycle length, cost height.
The utility model content
The purpose of this utility model is to overcome the defective and the deficiency of prior art, provides a kind of high sharp, and high cutting output, rapid heat dissipation have erasure effect, and manufacture craft is simple, the sintered carbide circular saw that financial cost is low.
The technical solution of the utility model is: a kind of sintered carbide circular saw comprises cutter head, matrix.Cutter head is made of hard alloy blocks and solder, and hard alloy blocks is irregularly shaped and is irregular alignment each other, and the tooth top corner angle are clearly demarcated, it is even to go out sword; Matrix is provided with " C " shape laser slotted, and circumferentially evenly distributes; Matrix between every two adjacent groups cutter head is provided with the dilatation joint of damascene copper rivet.
The beneficial effects of the utility model are: it is slow, yielding to have solved existing diamond saw blade cutting speed, and manufacturing process complexity, cycle are long, defective and deficiencies such as cost height, because hard alloy blocks is irregular alignment, go out sword voluntarily after top sword alloy block comes off when being beneficial to cutting, provide a kind of high sharp, high cutting output, rapid heat dissipation has erasure effect, and manufacture craft is simple, the sintered carbide circular saw that financial cost is low can be used for the broken sawing of materials such as armored concrete, pitch stone.
