Abstract
A small low-noise diamond circular saw blade comprises a saw blade base body and a diamond tool bit. The outer edge of the saw blade base body is evenly provided with circular bottom holes and a turn angle water slot with an inclined opening. The cylindrical area of the saw blade base body is provided with holes which are distributed in a staggered mode. The side edge of the diamond tool bit inclines towards the same direction and the tool bit cutting edge is provided with a slot opening. Through the structure, cooling performance is effectively improved when the small diamond circular saw blade conducts cutting at a high speed, the tool bit stress condition and the tooth portion stress condition in the cutting process are improved, cutting noise is lowered, cutting stability is improved, and service life of a blade body is prolonged.
Description
Technical field
The invention belongs to diamond disc manufacturing technology field, be specifically related to a kind of small-sized low noise diamond disc.
Background technology
The diamond disc that diameter is less than 680mm is commonly referred to small-sized diamond disc, small-sized diamond disc is due to advantages such as its volume are little, intensity is good, cutting performance is good, be widely used on the portable cutting equipments such as Hand saw, play an important role in fields such as building decoration, processing of stone, fire-fighting and rescues.But the high cutting of rotating speed owing to using when of small-sized diamond disc is fast, can cause that lamellar body local temperature is high, lamellar body withstands shocks, and power is large, because such small-sized diamond circular saw film base body thickness is less, the situations such as above-mentioned operating mode easily causes that cutting noise is large, lamellar body bird caging distortion, tooth portion crackle and cutter head come off, not only increased the application risk of saw blade, the service life of having reduced saw blade, and large cutting noise can cause compared with major injury to closely operator.
Summary of the invention
Technical problem to be solved by this invention is: reduce the cutting noise of small-sized diamond disc, reduce its application risk, extend its service life.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of small-sized low noise diamond disc, comprise saw bit matrix and diamond segment, saw bit matrix outward flange is evenly equipped with tank, saw bit matrix cylindrical area distribution has the hole of some, and described tank is a kind of corner tank that has round bottom hole and beveled, and round bottom hole and beveled communicate, described diamond segment lateral edges tilts to same direction, and cutter head cut edge has notch.
On the concentric circles that the central distribution of described saw bit matrix cylindrical region hole does not wait at the diameter taking saw bit matrix central point as the center of circle, and two adjacent round holes are dislocatedly distributed.
Described saw bit matrix cylindrical region refers to the region that is greater than saw bit matrix radius 2/3rds apart from saw bit matrix central point distance.
The angle of inclination of described beveled is 40-45 °.
The diameter of described hole is 1/50th-a thirtieth of saw bit matrix diameter.
Small-sized low noise diamond disc provided by the invention, because saw bit matrix outward flange is evenly equipped with the corner tank that has round bottom hole and beveled of some, corner has extended tank length, be conducive to accelerate tooth portion cooling, beveled is conducive to flow of cooling water and improves tooth portion stressed, be conducive to accelerate tooth portion cooling and prevent tooth portion bruise, stress concentration can fall in round bottom hole, and anti-water stopping trough cracks; Saw bit matrix cylindrical area distribution has dislocation densely covered hole, flow of cooling water when can accelerating cutting on the one hand, while making the high rotating speed cutting of saw blade, saw blade both sides can form certain thickness moisture film, can block on the other hand the transmission of lamellar body vibration, the noise while making the high rotating speed cutting of saw blade is effectively reduced; Diamond segment lateral edges tilts to have improved cutter head force-bearing situation to same direction, can effectively prevent from occurring that cutter head comes off in the high rotating speed cutting process of saw blade, cutter head cut edge has notch increases cutting edge quantity, the cutting vibrating can effectively reduce saw blade High Rotation Speed time and reduce noise.
Pass through said structure, when the present invention has effectively improved small-sized diamond disc high-speed cutting cooling performance, cutter head force-bearing situation and tooth portion force-bearing situation while having improved cutting, reduced cutting noise, more than conventional small-sized diamond disc cutting noise 110dB, this patent saw blade cutting noise of same specification can effectively be reduced to 95 ~ 105dB; Improved cutting stationarity and lamellar body service life, rationally under service condition, this patent saw blade improves approximately 25% than the conventional small-sized diamond disc of same specification average life average life.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of small-sized low noise diamond disc, comprise saw bit matrix 1 and diamond segment 2, saw bit matrix 1 outward flange is evenly equipped with tank 1.1, saw bit matrix 1 cylindrical area distribution has the hole 1.2 of some, and described tank 1.1 is a kind of corner tank that has round bottom hole 1.3 and beveled 1.4, and round bottom hole 1.3 and beveled 1.4 communicate, described diamond segment 2 lateral edges tilt to same direction, and cutter head cut edge has notch 2.1.
In the present invention, on the concentric circles that the central distribution of described saw bit matrix cylindrical region hole 1.2 does not wait at the diameter taking saw bit matrix 1 center point P as the center of circle, and two adjacent round holes 1.2 are dislocatedly distributed.The diameter of hole 1.2 is 1/50th-a thirtieth of saw bit matrix 1 diameter.
Saw bit matrix cylindrical region refers to the region that is greater than saw bit matrix 1 radius 2/3rds apart from saw bit matrix 1 center point P distance.
In the present invention, the angle of inclination a of described beveled 1.4 is 40-45 degree, and under this angle of inclination, drainage effect is best.
