A kind of pottery wood cutter
Technical field
The present invention relates to timber and composite wooden material machining field, be particularly applied to a kind of pottery of wood cutting
Porcelain wood cutter.
Background technology
It is known that sintex has been widely used for metal cutting, its plurality of advantages is mainly manifested in: 1. Stupalox
Having the highest hardness and wearability, its room temperature hardness reaches 91-95HRA, exceedes hard alloy;2. Stupalox has the highest
Thermostability, at 1200 DEG C, hardness is 80HRA, and intensity, toughness reduce less so that it is can be than the cutting of high 2-10 times of hard alloy
Speed carries out machining;3. there is high chemical stability, the most still have preferable antioxidation, anti-stick property;4. have
Relatively low coefficient of friction, ceramic tools in cutting adds the coefficient of friction in man-hour less than carbide tool;5. ceramic cutting tool material
Density is only equivalent to 1/4th of sintered carbide tool material, can improve the cutting speed (rotating speed) of cutter further;⑥
Sintex is cheap, abundant raw material.Above advantage is also applied to wood cutting manufacture field for sintex and provides all
Many advantages.
Compared to metal, timber is high anisotropy and uneven natural composite material, the extract of wood internal
Adhesive within matter, composite wooden material or the finishing material of outside and higher cutting speed, sintex is at cutting wood
During material, especially when upmilling process, cutting force is dynamic cutting force, and cutting force can be along with the change of cutting-edge
Change, dynamic cutting force cans be compared to the shock loading changed and equally acts on the cutting edge of sintex, easily causes cutter tipping and breaks
Damage.Therefore, it is considered that sintex is not suitable for being applied to the machining of timber and composite wooden material.
Summary of the invention
During the present invention is to solve sintex is applied to timber and composite wooden material cutting, cutting edge is easily occurred to collapse
Sword, fiber tearing have been scooped up, machining rough surface, especially timber knot position cutting quality poor and low the asking of cutter life
Topic, improves pottery wood cutter intensity, life-span and cutting quality.
To achieve the above object, present invention employs following technical scheme:
The present invention provides a kind of pottery wood cutter, is provided with a central shaft hole, at cutter hub including cutter hub and at this cutter hub

The central angle that central angle, pottery cutter tooth III and the pottery cutter tooth IV that pottery cutter tooth II is formed with pottery cutter tooth III is formed is respectively
It it is 13 °, 10 °, 7 °;And the ceramic cutter tooth I of arbitrary spiral pottery cutter tooth group is adjacent another spiral pottery cutter tooth group
The central angle that adjacent ceramic cutter tooth IV is formed is 15 °.Having the beneficial effects that of this structure design: at same spiral pottery cutter tooth
In group: pottery cutter tooth I is adjacent the central angle maximum that the adjacent ceramic cutter tooth IV of another spiral pottery cutter tooth group is formed,
Thus the cutting output of the ceramic cutter tooth I in each spiral pottery cutter tooth group is maximum, and in the most same spiral pottery cutter tooth group
Between pottery cutter tooth I and pottery cutter tooth II, between pottery cutter tooth II and pottery cutter tooth III, pottery cutter tooth III and pottery cutter tooth IV it
Between the central angle that formed reduce, it is achieved that the cutting output of same spiral pottery cutter tooth group is to be gradually reduced, it is ensured that cutting matter
The raising of amount.
As preferably: in arbitrary spiral pottery cutter tooth group: four pieces of ceramic cutters tooth (i.e. pottery cutter tooth I, pottery cutter tooth II,
Pottery cutter tooth III and pottery cutter tooth IV) on anterior angle be respectively 5 °, 10 °, 15 °, 20 °;Relief angle on four pieces of ceramic cutters tooth is
5°;The angle of wedge on four pieces of ceramic cutters tooth is respectively 80 °, 75 °, 70 °, 65 °.The design of this structure provides the benefit that: pottery cutter tooth I
Bending strength cutter tooth II maximum, ceramic bending strength secondly, the bending strength of pottery cutter tooth III reduces again, pottery cutter tooth IV
Bending strength minimum, it is achieved four pieces of ceramic cutter tooth Functional Requirements in each spiral pottery cutter tooth group, it is ensured that the angle of wedge is big
Pottery cutter tooth carries out the machining of big cutting output, and the ceramic cutter tooth that the angle of wedge is little carries out high-precision machining.This is mainly
Because the intensity of big angle of wedge pottery cutter tooth is higher and sharpness is relatively low, and the intensity of little angle of wedge pottery cutter tooth is low and sharpness
High.And four pieces of Stupalox rake angles in each spiral pottery cutter tooth group are to be gradually increased, and contribute to cutting quality gradually
Improve.
As preferably: the helical angle on four pieces of ceramic cutters tooth in arbitrary spiral pottery cutter tooth group be respectively 5 °, 4 °,
3°、2°.Having the beneficial effects that of this structure design: the spiral pottery cutter tooth group with helical angle can improve cutting of pottery cutter tooth

Sharp, and affect the intensity of cutting edge.Often being taken as 5 °~25 °, anterior angle involved in the present invention is the front cutter in pottery cutter tooth
The angle that face and its basal plane are formed, the most as indicated at 3.
The angle of wedge refers to rake face and the angle between knife face thereafter of pottery cutter tooth, and angle of wedge size has direct shadow to cutting
Ringing, the angle of wedge is bigger, and cutting tip intensity is the highest, so select angle of wedge size should to take in the case of ensureing sufficient intensity as far as possible
Little numerical value.The angle of wedge involved in the present invention is the rake face in pottery cutter tooth and the angle that knife face is formed thereafter, specifically
As indicated at 3.
Helical angle refers to the tangent line of circular helix and by acute angle folded between the face of cylinder straight edge line at point of contact.This
Helical angle involved in bright is that online and the straight edge line of ceramic wood cutter of this patent is (in i.e. for the cutting edge institute of pottery cutter tooth
The axis of arbor hole) between the angle that formed, the most as indicated at 3.
Central angle generally refers to adjacent two summit of a regular polygon and the angle of the line at its center, or
With the center of circle for vertex radius as both sides in a circle, also referred to as central angle.Central angle involved in the present invention is adjacent two
The angle formed between individual pottery cutter tooth, the most as indicated at 3.
The solution have the advantages that: the ceramic wood cutter of the present invention can realize cutting of timber and composite wooden material
Cut, it is ensured that machining precision and the reliability of cutter.Pottery cutter tooth tipping can be prevented effectively from, improve pottery cutter tooth intensity,
Increase the pottery cutter tooth life-span, reduce cutting surface roughness, improve cutting surface quality, improve machining efficiency.
