Abstract
The utility model provides a saw blade structure of a double-saw blade cutting machine, wherein each saw blade comprises a saw blade body and sawteeth. The saw blade structure is characterized in that a plurality of lug bosses are formed on one surface of the saw blade body of at least one saw blade close to tooth roots of the sawteeth, wherein the surface provided with the lug bosses is opposite to another saw blade, and the lug bosses are formed at intervals. The lug bosses are formed close to the tooth roots of the each saw blade at intervals, so that the heat quantity caused by friction between the lug bosses and the each relative saw blade can be radiated through the intervals between the lug bosses rapidly when the double-saw blade cutting machine operates, the cracking of a saw kerf caused by thermal deformation that is caused by superheating of each saw blade can be avoided, and the service life of each saw blade can be prolonged.
Description
Technical field
The utility model relates to a kind of cutting machine, especially a kind of saw blade that is used for cutter with double saw bits.
Background technology
Cutter with double saw bits adopts the saw blade that two direction of rotation are opposite, concentric is installed to turn round simultaneously; Can cut steel, aluminium section bar, timber, steel plate, aluminium sheet; Plastics; Multiple materials such as glass, ceramic tile, marble have characteristics such as efficient height, noise are low, Recoilless, vibrations are little, cutting is steady, are widely used in job sites such as fire control and disaster rescue, emergency repair, electric power, telecommunications construction, civil buildings, dismantlement work.
In order to prevent cutter with double saw bits hypotelorism between two saw blades and cause beating tooth when cutting, directly damage saw blade, need between two saw blades, leave certain clearance.Common way is the distance piece that an annular is set on saw blade face relative with another saw blade.Number be the Chinese patent disclosed " a kind of saw blade that adapts to cutter with double saw bits " of CN201760672U like Granted publication, nearly tooth root place is provided with the annular convex tendon in the blade body one side, and blade body also is provided with the annular convex tendon with a core bore edges place.
Yet the annular convex tendon that so is provided with is when cutting machine is worked; Convex tendon and relative saw blade friction can produce a large amount of heat; But because convex tendon is the annular of sealing, radiating efficiency is lower, and heat can not timely and effectively shed; Can cause the saw blade thermal deformation to cause the saw kerf bifurcated, and reduce the service life of saw blade.
The utility model content
The utility model technical problem to be solved provides a kind of saw-blade structure of cutter with double saw bits, has improved radiating efficiency, has improved radiating effect, has prolonged saw life, has solved the bifurcation that the saw blade thermal deformation causes.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of saw-blade structure of cutter with double saw bits; Each saw blade comprises blade body and sawtooth; It is characterized in that the said blade body of at least one saw blade face of another saw blade relatively is provided with a plurality of spaced apart boss near the tooth root place of said sawtooth.
The said boss that is positioned on the same saw blade evenly distributes, and lays respectively on the same circumference, can be so that saw blade is stressed evenly.
All be provided with said boss on two saw blades, the said boss on two saw blades lays respectively on waney concentric circles.Can increase the stability of cutter with double saw bits so that two saw blade stress equalizations.
Preferably, said boss is cylindrical.Not only be convenient to processing, and make saw blade stressed more stable.
Further preferred, the height of said boss is 0.3mm.Keep two gaps that saw blade is suitable thus, both avoided saw blade to beat tooth, avoid the residue after excesssive gap stays cutting again.
The quantity of the said sawtooth on the quantity that is positioned at the said boss on the same saw blade and this saw blade is identical.Guaranteed that further saw blade can be stressed uniformly.
Compared with prior art; The advantage of the utility model is: through a plurality of boss compartment of terrain being arranged in the nearly tooth root place of saw blade; Can be so that cutter with double saw bits when work boss and the relative fricative heat of saw blade can promptly distribute through interval therebetween; Avoid that saw blade is overheated to be caused thermal deformation and cause the saw kerf bifurcated, and can prolong the service life of saw blade.
Description of drawings
Fig. 1 is the sketch map of a saw blade of the utility model;
Fig. 2 is the assembling sketch map of two saw blades of the utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of saw-blade structure of cutter with double saw bits comprises blade body 1 and sawtooth 2.In order to prevent that cutter with double saw bits is at when work two saw blade hypotelorisms and cause beating tooth; Tooth root place near sawtooth 2 on the face of blade body 1 relative another saw blade of a saw blade is provided with a plurality of spaced apart boss 3; Boss 3 evenly distributes, and all is positioned on the same circumference.When cutting machine was worked, the blade body 1 fricative heat of boss 3 and relative saw blade can promptly distribute through the interval between the boss 3, has improved radiating efficiency effectively, avoided saw blade to cause distortion to cause the saw kerf bifurcated because of heat is excessive.Preferably, boss 3 is cylindrical, highly is about 0.3mm, and the quantity of the sawtooth 2 on its quantity and the same saw blade is identical.
Two saw blades of cutter with double saw bits can have only on the saw blade boss 3 is arranged, and also can on two saw blades boss 3 be arranged all.When all boss 3 being arranged on two saw blades,, be the assembling sketch map of two saw blades referring to Fig. 2; By knowing among the figure, the boss 3 on two saw blades is positioned on two waney concentric circles, is interspersed; Can increase the stability of cutter with double saw bits so that two saw blade stress equalizations thus.
The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection domain of the utility model.
