Abstract

The invention discloses a diamond blunt tool, which comprises a cutter body, wherein the cutter body is disc-shaped, a group of tooth holders are uniformly arranged on the circumference of the cutter body, and each tooth holder is provided with a cutter tooth. The diamond blunt tool comprises multiple cutter teeth, and each cutter tooth is independent so as to be convenient for replacing each damaged cutter tooth, the cost is reduced, the cutter teeth are made of diamond, and hardness, precision and stability are further better than the cutter teeth made of high-speed steel and alloy, so that the processed pencil has stable appearance and specification and high precision, the defective index of a product is reduced, profited by the hardness of the diamond, the service life durability of the tool is greatly reduced, more than 5000000 tools can be processed regularly, the replacement period of the tool is reduced, and the production efficiency of pencil processing is improved, so that the surface smoothness of the pencil end is greatly improved, a core break rate of a cartridge is reduced by 50%, the surface oil paint of the pen is difficult to crack, meanwhile, the processing noise of the tool is remarkably reduced, and the comfortableness of a work environment is provided.

Description

The flush cutter of diamond

Technical field

The present invention relates to woodwork pen and wood and mould a kind of processing work of pen, relate in particular to the edging of a kind of tip of the brushstyle of a writing or painting portion and the flush cutter of diamond of surperficial refine.

Background technology

At present to the woodwork pen or an edging of tip of the brushstyle of a writing or painting portion moulded by wood and surperficial refine mainly contains dual mode, a kind of is the refine of high-speed steel dise knife chip, the refine of another kind of carbide chip saw-blade type.

Adopt high-speed steel dise knife chip, blade rotates at a high speed, directly the end face of cutting pen.The cutting edge of the emery wheel that rotates an at a high speed reconditioning constantly blade keeps the sharp of cutting edge simultaneously.This mode critical piece is the high-speed steel blade, because the high speed steel material wearability is very poor, must adopt an emery wheel grinding constantly cutting edge of rotation at a high speed; Keep cutting edge sharp; High-speed steel blade high speed rotary motion, pen rotation rolling feeding, blade is along the mode grinding tip of the brushstyle of a writing or painting face of feeding.When adding the end face of Chinese realistic painting, surface paint bursts apart easily, and the pen core color is bonded at the side.

Adopt the carbide chip saw-blade type, saw blade is fixed on the cutter shaft, and contrary cut type formula is adopted in rotation at a high speed, and rotating speed is 2800 rev/mins, and feed speed is 8～20m/min.Saw blade service life is usually at 6～8 hours.Critical piece is a carbide chip.Saw blade rotatablely moves, pen rotation rolling feeding, and saw blade is along the mode grinding tip of the brushstyle of a writing or painting face of feeding.Weak point: the cutting edge material wear ability is poor, the saw blade low precision, and concentricity is bad, adds the disconnected easily core of core of Chinese realistic painting.The pen core of processing often has the chipping phenomenon, and there is obvious cut on the surface of tip of the brushstyle of a writing or painting face processing, and surface paint bursts apart easily.

Summary of the invention

Goal of the invention: for overcoming the deficiency of prior art, the present invention proposes a kind of long service life, makes tip of the brushstyle of a writing or painting smooth surface, is difficult for sticking pen core color, and pen core is not easy to rupture, the flush cutter of diamond of chipping.

Technical scheme: for solving the problems of the technologies described above, the flush cutter of diamond that the present invention proposes comprises cutter hub, and this cutter hub is in the form of annular discs, on the circumference of described cutter hub, is provided with one group of toothholder equably, and each toothholder is provided with a cutter tooth.

Described cutter hub and toothholder are one-body molded.

On described cutter hub, be provided with installing hole.

The anterior angle angular range of described cutter tooth is 0～25 degree, and the relief angles scope is 10～20 degree, and the axial angle angular range is 0～70 degree.

Described cutter tooth adopts diamond to process.

Beneficial effect: compared with prior art the present invention has the following advantages: the flush cutter of this diamond comprises a plurality of cutters tooth, and each cutter tooth independently is provided with, and is convenient for changing the single cutter tooth of each damage; Reduced cost, and cutter tooth employing diamond is processed its hardness, precision and the stable cutter tooth that all is much better than materials such as high-speed steel, alloy; The profile specification of the pencil that therefore processes is stable, precision is high, and therefore the percent defective of product is minimized, and has benefited from adamantine hardness; The cutter life durability increases greatly, can process more than 5,000,000 usually, has reduced cutter with the cycle of changing; Improved the production efficiency of pencil processing, tip of the brushstyle of a writing or painting surface smoothness is significantly promoted, the pen core core-breaking rate reduces 50%; The surface paint of pen is not easy to burst apart, and obviously reduces the noise of cutter processing simultaneously, and the comfortable working environment degree is provided.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done explanation further.

As shown in Figure 1, this cutter comprises cutter hub 1, and this cutter hub 1 is in the form of annular discs; On the circumference of described cutter hub 1, be provided with one group of toothholder 2 integrated equably with it; Each toothholder 2 is provided with a cutter tooth 3, and this cutter tooth 3, firmly is welded on the toothholder 2 through adding weldering mud and silver under 600～800 ℃ of situation at high temperature; Described cutter tooth 3 adopts diamond to process, and adopting the purpose of diamond is in order to improve the service life of cutter.Artificial diamond's stone material is made up of synthetic polycrystalline diamond material and carbide alloy between 0.3～2.0mm; Gross thickness is a scope between 1.0～6.0mm; It is a kind of wear-resisting especially, extra high material of hardness; Single crystal diamond material is made up of natural diamond material and carbide alloy, is a kind of wear-resisting, material that hardness is higher of higher level.

Knife-tooth structure like Fig. 2, the graver tool made of stones of Buddha's warrior attendant shown in 3; The angular range of the anterior angle 5 of this cutter cutter tooth 3 is between 0～25 degree; The angular range of relief angle 6 is 10～20 degree, and the angular range of axial angle is 0～70 degree, and wherein anterior angle 5 refers to the angle of cutter tooth rake face 7 and axial connecting line 8; Relief angle 6 is the angle of knife face 9 and tangent to periphery 10 behind the cutter tooth; Axial angle is cutter tooth axial line 12 and cutter hub face 11 angles.

As shown in Figure 4, on described cutter hub 1, be provided with installing hole 4 and be connected with machine shaft, in the process, pen 13 is when rolling, and cutter is by the machine shaft driven rotary, by the end edging and the refine of 3 pairs of pens 13 of cutter tooth.

The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
