Description

Diamond saw blade

Technical Field

The utility model relates to a diamond saw blade belongs to diamond sintering saw blade technical field.

Background

At present, a diamond saw blade is used when cutting non-metal materials such as stone, concrete and glass, the cutting direction of the diamond saw blade determines the rotating direction of work, and if the rotating direction is wrong, abnormal grinding occurs, large sparks occur, the saw cutting resistance is large, but the problems of difficult feeding, large temperature rise and the like occur. The sharpening direction of the cutter head of the hard alloy circular saw blade determines the rotating direction of the sawing operation, if the saw blade rotates reversely, the saw blade cannot work normally, and the saw blade is broken and scrapped.

The prior circular saw blade generally adopts the processes of printing, spraying or marking (including needle marking, laser marking and the like). Some manufacturers process air holes on the base body, and the shape of the air holes has the meaning of direction indication, but the pursuit of beauty easily causes ambiguity.

When the saw blade is used, for the rotation direction mark adopting printing and spraying, as the saw blade works, the matrix and a cutting object inevitably generate friction, and the mark can be damaged quickly. If the saw blade is not clamped once and is cut continuously until the saw blade is scrapped, no mark capable of determining the rotating direction exists when the saw blade is used for the second time. Such accidents occur sometimes. The marked saw blade is better than the saw blade which is printed or sprayed, but the marked depth is shallow, so the marked saw blade can be quickly rubbed off, and hidden troubles are caused.

Disclosure of Invention

The utility model discloses technical scheme's further improvement lies in: the tail part of the arrow is of an arc quadrilateral structure, the radial width close to the tail end of the tail part is larger than that of the front end of the tail part, and two adjacent lines of the tail part are smoothly transited by a fillet.

The utility model discloses technical scheme's further improvement lies in: the fillet radius is greater than 0.5 times the thickness of the substrate.

The utility model discloses technical scheme's further improvement lies in: in the diametrical direction, the arrow is arranged wholly outside the diameter of the blade pressing disc, inside the inner edge of the nozzle slot.

The utility model discloses technical scheme's further improvement lies in: the periphery of the saw blade is uniformly provided with a plurality of water gap grooves, in the circumferential direction, arrows are arranged in the range formed by two radiuses of two adjacent water gap grooves, and the minimum distance between each arrow and each water gap groove is larger than 5 times of the thickness of the base body.

The utility model discloses technical scheme's further improvement lies in: the number of the arrows is set to be 2-6 and the arrows are evenly distributed along the circumferential direction.

Since the technical scheme is used, the utility model discloses the technological progress who gains is:

the hollow rotating direction arrow provided by the application ensures that the saw blade keeps clear and accurate rotating direction identification in the whole life cycle; the arrow is divided into the head part and the tail part, so that the definition and accuracy of the identification degree of the arrow are ensured, and the strength of the matrix is also ensured; the circumference evenly distributed of arrow point has guaranteed the balance of saw bit, prevents that beat and vibration from appearing in rotatory in-process in the saw bit, and the direction of rotation arrow point of the fretwork of this application also possesses the effect of certain release stress simultaneously.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 4, a diamond saw blade comprises a disc-shaped base body 2 and a diamond cutter head 1 sintered on the outer circumference of the base body, wherein a mounting hole is arranged at the center of the base body 2, a hollow rotating direction arrow 3 is arranged on the base body 2, the arrow 3 consists of a head part and a tail part which are separated, the width of the adjacent part of the head part and the tail part is larger than the thickness of the base body 2, and the head part and the tail part are separated by two line segments which are parallel to each other at the adjacent position of the head part and the tail part.
