Hollow out the hole saw bit matrix
Technical field
The present invention relates to a kind of saw bit matrix, especially a kind of big plane hollows out the hole saw bit matrix.
Background technology
Saw blade is the common tool of the processing of building materials, timber, mechanical processing industry, and, cutting quick and stable easy to use because of it, applied range are widely used in stone material, timber, steel cutting processing.When but existing common common saw blade is worked,, cause severe noise to be polluted because violent impact and friction produce strong noise.Particularly the large saw blade of diameter more than φ 1600mm is big owing to the saw bit matrix plane, and contact interface is big, and not only noise is big during work, and heat radiation is slow, and water-cooled matrix plane is limited, and cooling effect is poor, and the cutting resistance is big.In order to solve the problem of noise pollution, compound silent saw blade, laser lancing saw blade, low noise saw blade are developed in saw blade manufacturing field at present, for example publication number is CN128804A, the described silent circular saw blade of Chinese invention patent ublic specification of application and manufacture craft and the silencing circular saw disc with damping noise-reducing base body of CN1288804A, mode by the multilayer stack keeps matrix strength, reduce noise, the patent No. is 01252017.9 the described laser lancing saw blade of patent of invention, reduces noise by laser at the accurate cutting of matrix surface noise reduction seam.But still there is cutting in above-mentioned technology resistance is big, cooling effect is poor, heat radiation is slow, and especially big plane saw bit matrix flatness is not good, difficulty of processing is big, cost is high, can't thoroughly eliminate the drawback of noise.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of matrix to be provided with and hollow out, the cutting resistance is little, effectively reduces noise, and good cooling results, flatness is good, technology is simple, low cost of manufacture hollow out the hole saw bit matrix.
The object of the present invention is achieved like this: a kind of hole saw bit matrix that hollows out, the matrix center has center mounting hole 1, matrix outer circumference equidistantly evenly is provided with tank 2, also be provided with processing locating hole 3 on the matrix, processing locating hole 3 hole heart place circumferences and tank 2 circumference between matrix on evenly setting hollow out hole 4.Described hole 4 water when saw bit matrix rotates that hollows out is provided with symmetrically and evenly at the streamline course bearing of matrix surface, and every row hollow out hole 4 with gradually far evenly distributed to matrix outer direction.The described shape that hollows out hole 4 can be water droplet shape, rhombus, square, rectangle, circle, ellipse, sickleshaped etc.The described shape that hollows out hole 4 adopts water droplet shape, and the camber line that formation water droplet shape hollows out is smooth connection.It is concentric that described processing locating hole 3 hole heart symmetries are positioned at matrix upper edge center mounting hole 1, on the circumference of radius greater than center mounting hole 2 radiuses.Described saw bit matrix material can be carbon constructional quality steel and structural alloy steel.
The hole saw bit matrix that hollows out of the present invention, employing processing locating hole hole heart place circumference and tank circumference between matrix on evenly setting hollow out the structure in hole, saw bit matrix and the contact-making surface that is cut material have been reduced, thereby reduce friction, reduced the cutting resistance, and hollow out and impact when cutting has been blocked in the hole and the propagation of the sound wave that friction produces, effectively eliminate noise, the setting that hollows out the hole does not simultaneously not only impact the tension force of this saw bit matrix, also strengthened the rigidity of saw blade under the high speed rotation status, guaranteed that this saw bit matrix keeps good flatness, not yielding during cutting; Because hollowing out hole streamline track of water when saw blade rotates is provided with symmetrically and evenly, cooling water when making the cutting of this saw bit matrix along with the rotation of saw bit matrix constantly from the through hole matrix surface of flowing through, the scope of matrix surface contact cooling water is bigger, the effect that cools is splendid, the setting and the arrangement mode that hollow out the hole have increased discharge greatly, blowdowns such as silt impurity in the time of can making cutting are taken away by current, blowdown is got rid of unobstructed, reduced the friction of blowdown, prolonged the service life of the living matrix of saw saw blade; Hollow out the setting symmetrically in hole in a large number, the air when having accelerated this saw bit matrix work flows, and has strengthened heat radiation and cooling; Because the large saw bits of diameter more than φ 1600mm has big plane, the setting that hollows out the hole has also reduced manufacturing cost and difficulty of processing.
