Description
Technical field
The utility model relates to a kind of saw blade, and more particularly, it relates to a kind of alloy circular saw bit.
Background technology
Saw blade is the general designation of the circular cutter of thin slice for cutting solid material, it can be divided into three kinds of diamond disc, high-speed steel circular saw blade and hard alloy saw blades, wherein, hard alloy saw blade is mainly used in the cuttings such as solid wood, furniture, wood-based plate, aluminium alloy, aluminium section bar, radiator, plastics, plastic-steel. And conventional sintered carbide circular saw is in cutting stone material, steel and timber process, can send very large noise, surrounding environment has been produced to huge noise pollution. Because saw blade noise is in use by saw blade generation of vibration in use, noise is larger, illustrate that saw blade is larger in the saw blade vibration of use procedure, especially, in the time of saw blade intrinsic frequency and saw blade vibration frequency generation resonance, the noise of generation can be larger; In addition, in the time of the metal materials such as cutting aluminium alloy, aluminium section bar, plastic-steel, can be easily because of chip removal difficulty and cutting resistance excessive cause saw blade or material overheated, this has reduced the service life of saw blade to a great extent.
For vibration and noise problem, the Chinese patent that the patent No. is CN201420824322.3 discloses a kind of ultra-thin boss carbide alloy circular saw bit, and it comprises matrix, boss, sawtooth, axis hole, silencing groove, noise reduction line, glue ring, damping glue, sawtooth; Boss center is provided with axis hole, periphery integral type is provided with matrix, matrix excircle is evenly provided with sawtooth, sawtooth forward position is welded and fixed and is provided with sawtooth, matrix upper and lower surface is provided with noise reduction line, and noise reduction line two ends are provided with glue ring, in glue ring and noise reduction line, is filled with damping glue, on matrix circumferential periphery, evenly open and cut silencing groove, in silencing groove, be filled with damping glue; This patent reduces noise and the resonance of saw blade by fill the mode of damping glue in glue ring and noise reduction line, but arranging scarce meeting, the mode of filling damping glue stops up glue ring and noise reduction line, affect the heat dispersion of saw blade, and the noise reduction line of said structure setting and the vibrations direction of saw blade exist deviation cannot reach best damping effect.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of alloy circular saw bit, and it is to improve the performance of heat radiation, damping and the noise reduction of alloy saw blade.
For achieving the above object, the utility model provides following technical scheme: a kind of alloy circular saw bit, comprise blade body and sawtooth, it is characterized in that, on the circumferential periphery of described blade body, open and cut damping trough, in described blade body, be provided with multiple corrugated radiating grooves, described radiating groove runs through blade body, the center line of described radiating groove is with to cross the circle at blade body center tangent, and point of contact is positioned at the tail end of blade body, and the two ends of described radiating groove are provided with louvre.
The utility model is more preferably: the corrugation pitch of described radiating groove is from along the gradually large setting of blade direction of sawtooth dorsad, and on radiating groove, corrugation pitch is tail end from gradually large one end.
The utility model is more preferably: the wave amplitude of described radiating groove is along the gradually large setting of blade direction of sawtooth dorsad.
The utility model is more preferably: described blade body includes discoidal matrix and boss, and described boss is integrally formed at that interior week of blade body is upper, and described radiating groove is located on boss, and described sawtooth is located on the excircle of matrix.
The utility model is more preferably: described damping trough is provided with noise reduction line away from one end of matrix excircle, is provided with louvre in the end of noise reduction line.
The utility model is more preferably: described noise reduction line is circular arc, fishtail or barb-type.
The utility model is more preferably: described noise reduction line is towards the edge bends of sawtooth dorsad.
In sum, the utility model alloy circular saw bit is opened saw blade is fanned to heat by louvre and corrugated radiating groove setting, by the vibrations that arrange to reduce saw blade of damping trough and radiating groove, and by being arranged to circular arc, the center line of radiating groove reaches better damping and erasure effect.

Detailed description of the invention
Referring to figs. 1 through Fig. 2, the utility model is described further.
Be a kind of embodiment of the utility model alloy circular saw bit as shown in Figure 1 to Figure 2, it comprises blade body 1 and sawtooth 11, blade body 1 includes discoidal matrix 12 and boss 13, be located at axis hole at boss 13 centers, boss 13 was integrally formed on the interior week of blade body 1, the thickness of boss 13 is greater than the thickness of matrix 12, and sawtooth 11 is located on the excircle of matrix 12.
On the circumferential periphery of blade body 1, open and cut damping trough 2, damping trough 2 is evenly located at around matrix 12 center, in the present embodiment, damping trough 2 is provided with six, damping trough 2 is provided with noise reduction line 5 away from one end of matrix 12 excircles, be provided with louvre 4 in the end of noise reduction line 5, noise reduction line 5 can be circular arc, fishtail or barb-type, the utility model adopts circular arc noise reduction line 5, resistance between chip increasing cutting member and the saw blade producing after suffered resistance and cutting while mainly cutting with sawtooth 11 due to vibration is relevant, and the main cut direction of saw blade dorsad of the vibrations direction producing, therefore by noise reduction line 5 court's edge bends of sawtooth 11 dorsad, make noise reduction line 5 can better reach the effect of damping and noise reduction.
