Abstract
The utility model discloses a kind of groove type cutter head sintered carbide circular saw, comprise with installing hole saw body, be arranged on saw body sawtooth circumferentially, saw-tooth tool bit, the cutting edge of saw-tooth tool bit is met to cutting direction, the root of saw-tooth tool bit offers groove, groove is made up of the first plane, the second plane and arc surface, the bottom of the first plane is connected with the first solder side, and top connects with one end of arc surface; The other end of arc surface connects with one end of the second plane, and the saw body between adjacent sawtooth and the space between groove form chip pocket.The utility model is when all kinds of core board of cutting processing, comparatively conventional saw blade is larger for the chip pocket of the sintered carbide circular saw of employing groove shapes cutter head, be conducive to the chip removal in cutting process and heat radiation, groove shapes cutter head volume less being conducive to reduces the power attenuation in welding process; Practical, cutting surfaces quality is more excellent, and cutting noise is less, and manufacturing process is more stable.
Description
Technical field
The utility model relates to a kind of groove type cutter head sintered carbide circular saw.
Background technology
Core board cutting sintered carbide circular saw traditionally, is made up of cutter head and saw bit matrix.Cutter head is fixed by welding on saw bit matrix toothholder, and cutter head root generally adopts chamfer shape.The chip pocket of tradition carpenter plate cutting sintered carbide circular saw is smaller, and in cutter head cutting process, noise is large and cutter head needs the Area comparison of grinding large, and time-consuming, production cost is higher.
Summary of the invention
In order to overcome the shortcoming that production cost is large, cutting efficiency is low etc. that existing core board cutting sintered carbide circular saw exists, the utility model provides a kind of can improve the novel hard alloy saw blade that core board cutting efficiency can reduce again production cost.
The technical solution adopted in the utility model is:
Groove type cutter head sintered carbide circular saw, comprise with installing hole saw body, be arranged on saw body sawtooth circumferentially, saw-tooth tool bit, first solder side and second solder side of described saw-tooth tool bit are welded on the toothholder of sawtooth, and the cutting edge of saw-tooth tool bit is met to cutting direction, it is characterized in that: the root of described saw-tooth tool bit offers groove, described groove is made up of the first plane, the second plane and arc surface, the bottom of the first described plane is connected with the first solder side, and top connects with one end of arc surface; The other end of arc surface connects with one end of the second plane, and the saw body between adjacent sawtooth and the space between groove form chip pocket.
Further, the length of the first described plane is 2-4mm, and the length of the second described plane is 0.8-1.5mm, and the first described plane, the arc surface of the second plane respectively with described are tangent, and the first described plane and the angle β of the second plane are 90 °; The arc length of described arc surface is 0.5-1.2mm.
Further, the end of described sawtooth has inclined-plane, and the incline direction on the inclined-plane of the end of multiple sawtooth is consistent; Described toothholder is opened in the sidepiece on the top near inclined-plane.
The beneficial effects of the utility model are embodied in: adopt the sintered carbide circular saw of groove type segment design when all kinds of core board of cutting processing, chip pocket is conducive to more greatly chip removal in cutting process and heat radiation, effectively can improve saw blade lifetime, in cutting process, noise is less; Groove shapes cutter head needs the area of grinding less, decreases production hour; Groove shapes cutter head saw disc is conducive to reducing the power attenuation in welding process, reduces production cost.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, groove type cutter head sintered carbide circular saw, comprise with installing hole 3 saw body 1, be arranged on saw body sawtooth 2 circumferentially, saw-tooth tool bit 4, first solder side 43 of described saw-tooth tool bit and the second solder side 42 are welded on the toothholder 21 of sawtooth, and the cutting edge of saw-tooth tool bit 4 is met to cutting direction, the root of described saw-tooth tool bit 4 offers groove 5, described groove 5 is made up of the first plane, the second plane and arc surface, the bottom of the first described plane is connected with the first solder side 43, and top connects with one end of arc surface; The other end of arc surface connects with one end of the second plane, and the saw body between adjacent sawtooth and the space between groove form chip pocket 41.
Further, the length b of the first described plane is 2-4mm, and the length a of the second described plane is 0.8-1.5mm, and the first described plane, the arc surface of the second plane respectively with described are tangent, and the first described plane and the angle β of the second plane are 90 °; The arc length of described arc surface is 0.5-1.2mm.
Further, the end of described sawtooth has inclined-plane 22, and the incline direction on the inclined-plane of the end of multiple sawtooth is consistent; Described toothholder is opened in the sidepiece on the top near inclined-plane.
Content described in this description embodiment is only enumerating the way of realization of inventive concept; protection domain of the present utility model should not be regarded as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
