Abstract

The utility model discloses a diamond end-flush diamond cutter. The diamond end-flush diamond cutter comprises a cutter body. The cutter body is discoid-shaped. A set of toothholders is installed on the circumference of the cutter body. Each toothholder is provided with a cutter tooth. The diamond end-flush diamond cutter comprises a plurality of cutter teeth and each cutter tooth is arranged independently. Each damaged cutter tooth is replaced conveniently and cost is reduced. Each cutter tooth is made of diamonds. The hardness, the precision and the stability of the diamond cutter teeth are superior to the cutter teeth which are made of high-speed steel, alloy and the like. Therefore, processed pencils are stable in appearance specifications and high in precision so that rejection rate of products is reduced. The durability of the service life of the cutter is improved greatly benefited by the hardness of the diamonds. Normally, more than five million pencils are processed. Replacing cycle of the cutter is reduced and production efficiency of pencil processing is improved. Surface smoothness of pencil ends is improved largely and core-breaking rate of pencil cores is reduced by fifty percent. Paint on pencil surfaces is not cracked easily. Meanwhile, noise of the cutter processing is reduced obviously and work environmental comfort level is offered.

Description

The flush cutter of diamond

Technical field

The utility model relates to a kind of processing work that woodwork pen and wood are moulded pen, relates in particular to the edging of a kind of tip of the brushstyle of a writing or painting section and the flush cutter of diamond of surperficial refine.

Background technology

Edging and the surperficial refine of at present woodwork pen or wood being moulded tip of the brushstyle of a writing or painting section mainly contain dual mode, and 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 High Rotation Speed, the directly end face of cutting pen.The cutting edge of the blade of the emery wheel of High Rotation Speed reconditioning constantly simultaneously keeps the sharp of cutting edge.This mode critical piece is the high-speed steel blade, because the high speed steel material wearability is very poor, must adopt the emery wheel grinding constantly cutting edge of a High Rotation Speed, keep cutting edge sharp, high-speed steel blade high speed rotary motion, a rotary 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 easily bursts apart, and the pen core color is bonded at the side.

Adopt the carbide chip saw-blade type, saw blade is fixed on cutter shaft, and High Rotation Speed adopts contrary cut type formula, and rotating speed is 2800 rev/mins, and feed speed is 8～20m/min.Saw blade lifetime is usually at 6～8 hours.Critical piece is carbide chip.Saw blade rotatablely moves, a rotary 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, and the core that adds Chinese realistic painting is disconnected core easily.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 easily bursts apart.

The utility model content

The utility model purpose: for overcoming the deficiencies in the prior art, the utility model proposes a kind of long service life, make tip of the brushstyle of a writing or painting smooth surface, be difficult for sticking pen core color, 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 the diamond that the utility model proposes comprises cutter hub, and this cutter hub is in the form of annular discs, is provided with equably one group of toothholder on the circumference of described cutter hub, and each toothholder is provided with a cutter tooth.

Described cutter hub and toothholder are one-body molded.

Be provided with installing hole on described cutter hub.

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 make.

beneficial effect: compared with prior art the utlity model has following advantage: the flush cutter of this diamond comprises a plurality of cutters tooth, and each cutter tooth independently arranges, be convenient for changing the single cutter tooth of each damage, reduced cost, and cutter tooth adopts diamond to make, its hardness, precision and stability all is much better than high-speed steel, the cutter tooth of the materials such as alloy, the profile specification of the pencil that therefore processes is stable, precision is high, therefore the percent defective of product is minimized, have benefited from adamantine hardness, the cutter life durability increases greatly, usually can process more than 5,000,000, 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, obviously reduce simultaneously the noise of tool sharpening, the comfortable working environment degree is provided.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, this cutter comprises cutter hub 1, this cutter hub 1 is in the form of annular discs, be provided with equably one group of toothholder 2 integrated with it on the circumference of described cutter hub 1, each toothholder 2 is provided with a cutter tooth 3, and this cutter tooth 3, firmly is welded on toothholder 2 by adding weldering mud and silver in 600～800 ℃ of situations at high temperature, described cutter tooth 3 adopts diamond to make, and adopting the purpose of diamond is in order to improve cutting-tool's used life.Artificial diamond's stone material is comprised of synthetic polycrystalline diamond material and the carbide alloy between 0.3～2.0mm, gross thickness is scope between 1.0～6.0mm, it is a kind of wear-resisting especially, extra high material of hardness, single crystal diamond material is comprised of natural diamond material and carbide alloy, is a kind of wear-resisting, material that hardness is higher of higher level.

The knife-tooth structure of Buddha's warrior attendant graver tool made of stones as shown in Fig. 2,3, 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, wherein the angle of anterior angle 5 finger cutter tooth rake faces 7 and axial connecting line 8; Relief angle 6 is the angle of knife face 9 and tangent to periphery 10 after cutter tooth; Axial angle is cutter tooth axial line 12 and cutter hub face 11 angles.

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

The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
