Abstract
The utility model relates to a diamond-coated round saw blade, which includes a round blade body. A blade shaft hole is arranged at the center of the round blade body, and two fabrication holes symmetric to the blade shaft hole are arranged at both ends of the blade shaft hole. A plurality of radial expansion grooves with identical length and width are evenly arranged at the edge groove bottom of the round blade body. A round hole with the width larger than that of the expansion groove is arranged at the end of each expansion groove closer to the blade center, and the round hole is filled with vibration absorption material. The round blade body is also provided with the same thin muffling seams, each thin muffling seam is provided with stress relieving holes at both ends, and the thin muffling seams are evenly distributed on the round blade body. The cutting edge of the round saw blade is sintered with a composite diamond piece. The utility model is featured with reduced vibration and noise, saved time of saw blade replacing, and greatly improvement of production efficiency.
Description
Technical field
The utility model relates to a kind of saw blade, particularly be a kind ofly to have vibration damping and reducing the noise function and saw blade tip cutting edge material is the saw blade of diamond composite sheet.
Background technology
Particieboard, middle-high density plate, thick china, fire wall, composite floor board materials such as (the A1203 abrasion-proof paper are posted on the surface) are widely used in industries such as building, furniture.To the processing method of wood materials, cutting is very important means, and as the saw blade of one of cutting element, its effect is very big.Along with industrial production and to the raising of the demand of product quality, rotating speed to saw blade is also had higher requirement, because high rotating speed, the noise that saw blade sends becomes one of severe noise source of wood processing enterprise, influence workman's body and mind Jiankang, and reduced production efficiency.
The noise source of saw blade mainly contains four:
1. aerodynamic noise;
2. saw blade vibrates the vibration noise that produces;
3. the impinging radiation noise that produces during the saw blade cutting material;
4. the fricative frictional noise of saw blade and workpiece;
5. cutting resistance.
The approach of control and reduction noise: weaken at the sound source place, in passing the ripple way, weaken, weaken at Ren Erchu.But being the most thorough, the most effective at sound source place radical cure noise in fact, also is most economical.
For saw blade tip, its effect in working angles also is very crucial, in the market the saw blade of Chu Shouing, process above timber, select the saw blade of carbide alloy for use, this saw blade needs often to repair in process, matrix is subjected to friction to be easy to generate the dishization phenomenon, thereby can not stablize processing for a long time, influence processing effect, particularly when producing in enormous quantities, need repeatedly change saw blade, influence production efficiency so greatly.
Summary of the invention
The purpose of this utility model is, a kind of diamond circular saw blade is provided, and cutter head partly adopts PCD (poly-diamond), makes the life-span improve tens times, and body portion carries out a large amount of improvement, and can vibration damping and reduction noise.
For realizing this purpose, the technical solution adopted in the utility model provides a kind of diamond circular saw blade, comprises a saw blade body, has the cutter shaft hole at saw blade body knife face circle centre position, and two ends, cutter shaft hole have two fabrication holes about cutter shaft hole symmetry; Wherein, cut out radially heat expansion groove with equal length and width at the edge teeth bottom land place of described saw blade body, described heat expansion groove should be distributed on the saw blade body, and end is provided with a circular hole greater than the heat expansion well width in the nearly center of circle of described heat expansion groove, filling absorbing material on it; Be provided with identical noise reduction finedraw on the saw blade body, the two ends of described noise reduction finedraw have the destressing aperture, and described noise reduction finedraw should be distributed on the saw blade body; Sintering has the diamond composite sheet at the saw blade head cutting edge place of described saw blade body; Described heat expansion slot length is 1/3rd of a saw blade body knife face radius, and the width of described heat expansion groove is a heat expansion slot length 1/4th; Described choke material is a copper; Described heat expansion groove is at least four, and the number of described noise reduction finedraw equates with heat expansion groove number.
Advantage of the present utility model is, has reduced the vibration and the noise of saw blade, has saved the time used when changing according to sheet, has improved production efficiency greatly.
Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.
Description of drawings
Fig. 1 is a vertical view of the present utility model.
Description of reference numerals: 1-saw blade body; 2-heat expansion groove; 3-clogs copper; 4-noise elimination finedraw; 5-destressing hole; 6-cutter shaft hole; The 7-fabrication hole; 8-diamond composite sheet.
The specific embodiment
See also shown in Figure 1, this figure is a vertical view of the present utility model, the home position place opens a cutter shaft hole 6 on saw blade body 1 knife face, be arranged with two fabrication holes 7 at the two ends in cutter shaft hole 6, being used for processing location uses when fastening, sentence 72 ° at edge teeth's bottom land of saw blade body 1 and cut out five radially heat expansion grooves 2 for spacing, described five heat expansion groove 2 length are identical, heat expansion groove 2 length are 1/3rd of saw blade body 1 radius, and heat expansion groove 2 width are 1/4th of heat expansion groove 2 length; End is provided with the circular hole of diameter greater than heat expansion groove 2 width in the nearly center of circle of heat expansion groove 2, is plugged with absorbing material filling copper 3 in circular hole, and described filling copper 3 can effectively reduce vibration and noise.
According to several groups of identical finedraws that on the body 1 of saw blade, cut out definite shape shown in Figure 1, described seam is noise elimination finedraw 4, they are separate, with 72 ° is the surface that spacing is distributed on saw blade body 1, two ends at described every noise elimination finedraw 4 has aperture, this hole is destressing hole 5, and purpose is that the stress of avoiding causing owing to the seam of being opened is concentrated; The finedraw of this saw blade body 1 inside, vibrational line from the saw blade edge to the center is cut off, reduced vibration, having reduced the auxilliary of noise penetrates, thereby reached the purpose that reduces noise, because described noise elimination finedraw 4 is arranged on saw blade body 1 inside, can not influence this intensity that in working angles, is shown of saw blade simultaneously.
Sintering has diamond composite sheet 8 at saw blade body saw blade head cutting edge place, when machining, and described diamond composite sheet 8 elder generation and timber effects.Reduce the dish phenomenon that metal fatigue and frictional heat fatigue are produced, thereby realized long-time stable processing, reduced the number of times of changing saw blade when producing in enormous quantities, also saved the time used when changing saw blade simultaneously, improved production efficiency greatly.
More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
