Abstract
The utility model discloses a saw bit, which comprises a circular substrate. The circle center of the substrate is provided with a positioning hole. The saw bit is characterized in that at least one anti-vibration groove is arranged on the circular substrate along the circumference. The anti-vibration groove is filled with resin. The utility model makes the anti-vibration groove filled with the resin absorb or disperse external stress when the saw bit carries out high-speed rotating cutting by processing the anti-vibration groove on the saw bit substrate and filling the resin in the anti-vibration groove so as to achieve the effect of reducing noise. Compared with the conventional saw bit anti-vibration groove, the saw bit anti-vibration groove of the utility model has more compact structure and shorter length and the strength of the saw bit is greatly improved.
Description
Technical field
The utility model relates to a kind of cutting tool, relates in particular to a kind of saw blade of cutting tool.
Background technology
Saw blade is the common tool of construction material, timber processing, machining, and is easy to use because of it, and cutting is widely used in the cutting processing of stone material, cement, timber, metal material fast.Yet when working, conventional common saw blade produces the severe noise pollution because of rotating cutting at a high speed, particularly large saw blade is because the saw bit matrix plane is big, contact interface is big, noise is big during work. at present, saw blade manufacturing field has in saw bit matrix processing the vibrationproof groove is set, and makes the saw blade operating noise decrease, but in order to reach desirable noise reduction, the length of vibrationproof groove is provided with very longly, cause saw bit matrix intensity significantly to reduce, become fragile, the life-span is short.
The utility model content
The utility model provides a kind of novel saw blade, and the shortcoming that overcomes above-mentioned conventional blade reaches the purpose of high strength, low noise.
The technical solution of the utility model is: a kind of saw blade, comprise circular base, and described matrix circle centre position offers locating hole, it is characterized in that: described circular base upper edge circumferentially is provided with at least one vibrationproof groove, is filled with resin in the described vibrationproof groove.
Preferably, described vibrationproof groove is a waveform, and its crest and trough narrow along its centerline direction.
Preferably, the center line of described vibrationproof groove is a camber line.
Preferably, the groove width of described vibrationproof groove changes setting between each crest and trough.Preferably, described circular base comprises the circumferential equally distributed vibrationproof groove in a plurality of edges.
The utility model is by processing vibrationproof groove on saw bit matrix, and in the vibrationproof groove potting resin, make saw blade when rotation is cut at a high speed, the vibrationproof groove that is filled with resin absorbs and the dispersion external stress, reached the effect that reduces noise, saw blade vibrationproof groove of the present utility model is with respect to traditional saw blade vibrationproof groove, and structure is compact more, length is shorter, and the intensity of saw blade is greatly improved.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of the utility model saw blade.
Fig. 2 is the enlarged drawing of the vibrationproof groove of the utility model saw blade.
The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described in further detail.
As shown in Figure 1, the saw blade of the utility model preferred embodiment comprises circular base 1, along the circumferential equally distributed a plurality of sawtooth 2 of matrix, the circle centre position of matrix 1 offers locating hole 3. circular bases 1 and is provided with the circumferential equally distributed vibrationproof groove 4 in a plurality of edges, is filled with resin 5 in the vibrationproof groove 4.
As shown in Figure 2, the saw blade vibrationproof groove 4 of the utility model preferred embodiment is a waveform, and its crest 6 and trough 7 narrow along its centerline direction, and the center line of vibrationproof groove 4 is a camber line.The groove width of vibrationproof groove changes setting between each crest and trough.
When the saw blade of the utility model preferred embodiment rotates cutting at a high speed, the vibrationproof groove that is filled with resin absorbs and dispersion portion of external stress, reached the effect that reduces noise, with respect to conventional blade vibrationproof groove, the vibrationproof groove of the utility model preferred embodiment is shorter and smaller, makes the intensity of saw bit matrix be greatly improved.
Above embodiment only is a kind of of the utility model embodiment, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (5)
