Abstract
The utility model discloses a circular saw blade with good chips removal effect comprising sawteeth in interval arrangement on the outer circumference of the saw blade portion, the front and back two adjacent sawteeth constituting a chip-hold groove between the two, wherein the blade portion is fixedly provided with at least one scraper; wherein a blade of the scraper is slightly more protruding than the side surface of the saw blade portion, and the blade possesses an installation angle which enables the chips to be swung out through the centrifugal force produced by the rotating of the saw blade portion. The arrangement of blade can discharge wood chips which are extruded between the saw blade portion and the timber, which reduces friction and extruding imposed on saw blade portion, prolongs service lifetime of the saw blade portion, reduces changing and adjustment of saw blade portion, increases production efficiency as well as increases stability of timber cutting size. The circular saw blade of the utility model can find application to timber processing and processing of other materials.
Description
Technical field
The utility model relates to the saw blade that sawing machine is used.
Background technology
Follow the progress of log blank cutting machine bed technique, the efficient and the quality of blanking a slice of original band saw seem backward day by day.The appearance of multi-disc sawing machine has improved the efficient and the quality stability (with criticizing the uniform thickness uniformity that reaches monolithic timber gauge) of log blanking greatly, is widely used in timber processing in enormous quantities.The innovation of machine tool technology has improved efficient, but its matching used saw blade is conventional rip cutting saw blade, though it has been finished multi-disc and has cut simultaneously, the multi-disc discharging, but in use, because chip removal difficulty, the saw blade of rotation produces high temperature rapidly with a large amount of wood chips in extruding, friction process at a high speed, for reducing temperature, the water flushing is cooled off, and has aggravated the degree of difficulty of chip removal again, under the high temperature and extruding of this vicious circle, be easy to make saw blade distortion, dynamic property to be destroyed, thereby cause saw blade to be scrapped.And at this high temperature, be easy to cause under the high-drag that high extruding produces change defectives such as material size instability, damage lathe, cause processing cost significantly to increase, efficient reduces, the timber size instability of processing.
The utility model content
The technical problem that the utility model solved provides the effective saw blade of a kind of chip removal.
The technical scheme that its technical problem that solves the utility model adopts is: this saw blade comprises the sawtooth that is disposed on the blade bodies excircle, before and after constitute chip pocket between adjacent two sawtooth, be installed with at least one scraper on the described blade bodies, the blade of described scraper is slightly protruding in the side of blade bodies, and this scraper also has the setting angle that the centrifugal force that can utilize the blade bodies rotation time to be produced discharges the bits material that scraped by its blade.
As improvement, there is the trench bottom of at least one chip pocket to extend and then form the dark chamber of appearance bits to the center position of blade bodies, the rear wall in this dark chamber of appearance bits is provided with described scraper.Scraper is fixed on the rear wall that holds the dark chamber of bits can makes scraper be in desirable stress, guarantee firm when it uses, and a large amount of bits material are brought under the effect of scraper to be held in the dark chamber of bits, the centrifugal force that is produced when rotating by blade bodies then will be considered material to be worth doing and outwards be thrown away, and can improve the chip removal effect.
As improvement, the side of described blade bodies is provided with at least one and holds the bits through hole, and the rear wall of this appearance bits through hole is provided with described scraper.Scraper is fixed on the rear wall that holds the bits through hole can makes scraper be in desirable stress, guarantee the firm of its use, and hold the bits through hole and be convenient to scraper is fixed on needed position, reach more sufficient chip removal effect by being provided with.
As improvement, described scraper has the blade that lays respectively at the blade bodies both sides.Therefore can discharge blade bodies both sides bits material simultaneously.
As a kind of optimal way of scraper setting angle, thus described scraper along blade bodies radially from outside to inside and extend towards top rake between line between the center of circle of the outer end points of the blade make this scraper and blade bodies and the described blade and form the inclination angle.In fact, this structure makes scraper form the chip removal mode of negative rake, thereby the centrifugal force that is produced when utilizing the blade bodies rotation outwards moves the bits material that scrapes.
Must be pointed out that involved " preceding ", " back " relation in the technique scheme are that direction of rotation when using with saw blade is as basis for estimation; " interior " that relates to, " outward " relation radially are basis for estimation with blade bodies, hereinafter will be further described in conjunction with the accompanying drawings, do not repeat them here.
The beneficial effects of the utility model are: by scraper is set the wood chip that is squeezed in blade bodies and timber centre is in a large number discharged, reach the purpose of abundant chip removal, thereby friction and extruding have been reduced to saw blade, prolonged the life-span of saw blade, reduce saw blade and change, adjust the frequency, closely enhance productivity, improved the dimensional stability of wood cutting simultaneously again.Certainly, saw blade of the present utility model is not only applicable to the processing of timber, can be used for the processing of other multiple materials yet.

Be labeled as among the figure: blade bodies 1{ side 101}, sawtooth 2, chip pocket 3, the dark chamber 4 of appearance bits, scraper 5{ blade 501}, appearance bits through hole 6, direction of rotation 7, line 8, inclination alpha.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Shown in Fig. 1～3, " preceding " that the application relates to, the direction of rotation 7 when " back " relation is used with saw blade are basis for estimation, are called " forward " motion along moving of direction of rotation 7." interior " that the application relates to, " outward " relation radially is a basis for estimation with blade bodies, and moving of approaching along the diameter of blade bodies towards its pivot is called " inwardly " and moves.
As shown in Figure 1 and Figure 4, this saw blade comprises the sawtooth 2 that is disposed on blade bodies 1 excircle, before and after constitute chip pocket 3 between adjacent two sawtooth 2, wherein the trench bottom of two chip pockets 3 extends and then forms the dark chamber 4 of appearance bits to the center position of blade bodies 1, be provided with scraper 5 on the rear wall in this dark chamber 4 of appearance bits, the blade 501 of described scraper 5 both sides is slightly protruding in respectively the two sides 101 of blade bodies 1, thereby and this scraper 5 along blade bodies 1 radially from outside to inside and extend towards top rake between line 8 between the center of circle of the outer end points of the blade 501 make this scraper 5 and blade bodies 1 and the described blade 501 and form inclination alpha, the size of this inclination alpha is respectively 10 °.Scraper 5 is fixed on the rear wall that holds the dark chamber 4 of bits can makes scraper 5 be in desirable stress, guarantee the firm of its use, and a large amount of bits material are brought under the effect of scraper 5 to be held in the dark chamber 4 of bits, the centrifugal force that is produced during then by blade bodies 1 rotation will be considered material to be worth doing and outwards be thrown away, and can improve the chip removal effect.
