Abstract
A saw blade basal body with a fishhook-shaped silencing seam comprises a saw blade basal body, wherein the center of the saw blade basal body is provided with a center hole, a water groove is evenly arranged on the periphery of the saw blade basal body, the bottom of the water groove is provided with a silencing seam, and the silencing seam is in a fishhook shape. The saw blade basal body with a fishhook-shaped silencing seam adopts a line cutting or laser cutting method to process a fishhook-shaped narrow seam at the bottom of a normal saw blade water groove, and the shape of the seam is in afishhook shape, stress concentration can be effectively prevented, vibrating sound wave which is generated is stopped along the periphery direction of the saw blade when the saw blade rotates, and noise can be effectively lowered.
Description
Technical field
The utility model relates to a kind of cutting diamond circular saw film base body, a kind of especially circular saw blade substrate with barb-type noise reduction seam.
Background technology
The metal saw blade is having a wide range of applications aspect the ornament materials such as cutting stone material, timber, pottery, aluminium alloy.Saw blade commonly used smooth and easy in order to guarantee to cut all is provided with tank between knuckle-tooth and the tooth, the recrement that produces when being used to get rid of cutting outside.Along with the continuous lifting of saw blade cutting speed, noise is increasing, and is also more and more higher for the requirement of saw blade noise abatement, for this reason, becomes a problem demanding prompt solution if reduce cutting noise.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of under the prerequisite that does not change the saw bit matrix structure, by design a kind of novel barb-type noise reduction seam at the saw bit matrix bottom of gullet, blocks the sound wave that vibration produces with this, reaches the effect that reduces noise.
The purpose of this utility model is achieved in that a kind of saw blade substrate with fishhook-shaped noise-damping slots, comprises saw bit matrix, and the saw bit matrix middle part is provided with centre bore, and along evenly being provided with tank on the saw bit matrix circumference, bottom of gullet has the noise reduction seam, and the noise reduction seam is barb-type.
The saw blade substrate with fishhook-shaped noise-damping slots that the utility model provides, adopt the method for line cutting or laser cutting to process the narrow slit of barb-type in the bottom of conventional saw blade tank, this seam be shaped as barb-type, can prevent effectively that stress is concentrated, when saw blade rotates, the vibration sound wave that produces can be blocked along the saw blade circumferencial direction, can effectively reduce noise.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises saw bit matrix 1, and saw bit matrix 1 middle part is provided with centre bore 2, and along evenly being provided with tank 3 on saw bit matrix 1 circumference, tank 3 bottoms have noise reduction seam 4, and noise reduction seam 4 is a barb-type.Noise reduction seam 4 adopts the method processing of line cutting or laser cutting to obtain.
Claims (1)
1, a kind of saw blade substrate with fishhook-shaped noise-damping slots, comprise saw bit matrix (1), saw bit matrix (1) middle part is provided with centre bore (2), along evenly being provided with tank (3) on saw bit matrix (1) circumference, it is characterized in that: tank (3) bottom has noise reduction seam (4), and noise reduction seam (4) is a barb-type.
