Abstract
The utility model discloses a saw blade. The saw blade comprises a circular arc metal blade body and a plurality of saw teeth distributed along the outer circumference of the circular arc metal saw blade body, wherein a hard alloy cutter head with acuity is embedded in a tooth socket of each of the saw teeth; a chip accommodating groove is formed below the hard alloy edge, so that the edge obtains a cutter retracting space when the cutter is sharpended. The saw blade disclosed by the utility model has the advantages of low cutting noise, low heat generated by cutting, smaller centrifugal force during rotation of the saw blade at a high speed and improved cutting quality.
Description
Technical field
The utility model relates to a kind of saw blade, especially mainly is a kind of saw blade with miniature carbide bit.
Background technology
For this sintered carbide circular saw, by convention, metal body toothholder and carbide bit are through 90 ° of welding.And carbide bit is also longer, usually at 8.0-11.0mm; In addition, Furniture Factory generally grinds again and all grinds rake face owing to the restriction of sharpening equipment.Like this, the rimmer knife head has caused the waste of resource on the contrary.
Moreover long carbide bit saw blade is when cutting material, and it is big that the rubbing surface of cutter head side and material cut face is wanted, and more is prone to produce a large amount of heat in metal cuttings, and aggravation saw body neighboring part causes the patellate distortion.
Summary of the invention
The utility model will overcome that existing metal circular saw frictional heating amount is big, the shortcoming of waste material, provides that a kind of centrifugal force is little, the frictional heat during sawing is low, also save the saw blade of material simultaneously.
The described saw blade of the utility model; The metal blade body 1 that comprises circular arc; And a plurality of sawtooth 2 along circular arc metal blade body 1 peripheral distribution; The toothholder of sawtooth 2 is inlayed the carbide bit 3 of band acutance, and the below of described carbide alloy 3 blades is provided with chip pocket 4, makes blade when whetting a knife, obtain the withdrawing space.
Further, the length of described carbide bit 3 is 4.0～5.5mm.
Further, the mosaic angle of described carbide bit and described toothholder is the 60-85 degree.
The technical scheme that the utility model adopts is: saw blade saw body periphery is circumferentially welded novel saw-tooth tool bit, has reduced the cutting heat that produces because of the cutter head side friction in the working angles greatly, has improved the intensity of blade body from another point of view; Simultaneously, reducing of saw-tooth tool bit weight makes that the centrifugal force of operating condition is to a certain degree reduced, and is beneficial to the stable cutting of body under running up, and helps to improve cutting quality and reduces noise, improves operating environment.
The utility model advantage is: cutting noise is low, and the heat that cutting produces is low, and the centrifugal force under saw blade rotates at a high speed is littler, has improved cutting quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sawtooth position partial enlarged drawing of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing:
In the accompanying drawing, 1, the saw blade body; 2, sawtooth; 3, carbide bit; 4, chip pocket; 5, saw blade endoporus
The described saw blade of the utility model; The metal blade body 1 that comprises circular arc; And a plurality of sawtooth 2 along circular arc metal blade body 1 peripheral distribution; The toothholder of sawtooth 2 is inlayed the carbide bit 3 of band acutance, and the below of described carbide alloy 3 blades is provided with chip pocket 4, makes blade when whetting a knife, obtain the withdrawing space.
Sawtooth 2 is on the circumference of body 1 evenly or uneven distribution.
The length of carbide bit 3 is 4.0～5.5mm.Carbide bit is processed through mould.It is chip pocket 4 that the below of carbide alloy 3 blades is provided with the groove, supplies smear metal to discharge, and the withdrawing space when whetting a knife is provided simultaneously, in order to avoid smear metal damages blade body 1.
The utility model saw blade is installed on the saw through endoporus 5.
The mosaic angle r of described carbide bit and described toothholder is the 60-85 degree.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; Should not being regarded as of protection scope of the present invention only limits to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
Claims (3)
1. saw blade; The metal blade body that comprises circular arc; And a plurality of sawtooth along circular arc metal blade body peripheral distribution; It is characterized in that: the toothholder of described sawtooth is inlayed the carbide bit of band acutance, and the below of described carbide-tipped cutter bit is provided with chip pocket, makes blade when whetting a knife, obtain the withdrawing space.
2. described saw blade as claimed in claim 1 is characterized in that: the length of described carbide bit is 4.0～5.5mm.
3. according to claim 1 or claim 2 described saw blade, it is characterized in that: the mosaic angle of described carbide bit and described toothholder is the 60-85 degree.
