Description
Technical field
The application be the application for a patent for invention 201610697427.0 submitted for 19th for 08 month in 2016 (it is entitled " one
Kind ceramic wood cutter ") divisional application.
The present invention relates to timber and composite wooden material machining fields, are particularly applied to a kind of spiral shell of wood cutting
Revolve ceramic knife-tooth structure.
Background technique
It is well known that sintex has been widely used for metal cutting, plurality of advantages is mainly manifested in: 1. Stupalox
Tool has very high hardness and wearability, and room temperature hardness reaches 91-95HRA, is more than hard alloy；2. Stupalox has very high
Heat resistance, hardness is 80HRA at 1200 DEG C, and intensity, toughness reduces less, cutting that can be 2-10 times higher than hard alloy
Speed carries out machining；3. there is high chemical stability, still there is preferable anti-oxidant, anti-stick property at high temperature；4. having
Lower coefficient of friction, coefficient of friction when ceramic tools in cutting is processed are lower than hard alloy cutter；5. ceramic cutting tool material
Density is only equivalent to a quarter of sintered carbide tool material, can be further improved the cutting speed (revolving speed) of cutter；⑥
Sintex is cheap, abundant raw material.The above advantage also provides for sintex applied to wood cutting manufacture field all
More advantages.
Compared to metal, timber is the extract of high anisotropy and non-uniform natural composite material, wood internal
Finishing material and the higher cutting speed of adhesive or outside inside matter, composite wooden material, sintex is in cutting wood
During material, especially in upmilling process, cutting force is dynamic cutting force, cutting force can with the variation of cutting-edge and
Variation, the shock loading that dynamic cutting force cans be compared to variation equally act on the cutting edge of sintex, easily cause cutter tipping broken
Damage.Therefore, it is considered that sintex is not suitable for the machining applied to timber and composite wooden material.
Summary of the invention
The present invention provides a kind of spiral ceramics knife-tooth structure, and solution is that spiral ceramics knife-tooth structure is applied to timber and wood
When composite material is cut, Yi Fasheng cutting edge tipping, fiber tearing scoop up, machining rough surface, especially timber knot
Position cutting quality difference and the low problem of cutter life improve spiral ceramics knife-tooth structure and have spiral ceramics knife-tooth structure
Ceramic wood cutter intensity, service life and cutting quality.
To achieve the above object, present invention employs technical solutions below:
The present invention provides a kind of spiral ceramics knife-tooth structure, including four pieces of ceramic cutters tooth and four pieces of Stupalox toothholders, described
Four pieces of ceramic cutters tooth are respectively corresponded and are fixed on four pieces of Stupalox toothholders；
Wherein: four pieces of Stupalox toothholders are respectively Stupalox toothholder I, Stupalox toothholder II, Stupalox toothholder III and ceramics
Cutter tooth seat IV, four pieces of ceramic cutters tooth are respectively the ceramic cutter tooth I being fixed on Stupalox toothholder I, are fixed on Stupalox toothholder II
On ceramic cutter tooth II, the ceramic cutter tooth III being fixed on Stupalox toothholder III, the Stupalox that is fixed on Stupalox toothholder IV
Tooth IV；
During ceramic cutter tooth I and ceramic cutter tooth II are formed by central angle, ceramic cutter tooth II and ceramic cutter tooth III are formed by
It is respectively 12~14 °, 9~12 °, 5~9 ° that heart angle, ceramic cutter tooth III, which are formed by central angle with ceramic cutter tooth IV,；
Anterior angle on four pieces of ceramic cutters tooth is 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 beneficial effect of structure design is: ceramic cutter tooth I
The bending strength of maximum, the ceramic cutter tooth II of bending strength secondly, the bending strength of ceramic cutter tooth III reduces again, ceramic cutter tooth IV
Bending strength is minimum, realizes four pieces of ceramic cutter tooth Functional Requirements in each spiral ceramics cutter tooth group, guarantees the big pottery of the angle of wedge
Porcelain cutter tooth carries out the machining of big cutting output, and the small ceramic cutter tooth of the angle of wedge carries out high-precision machining.This be mainly because
For big angle of wedge ceramics cutter tooth intensity is higher and sharpness is lower, and the intensity of small angle of wedge ceramics cutter tooth is low and sharpness
It is high.And four pieces of Stupalox rake angles in each spiral ceramics cutter tooth group are to be gradually increased, and facilitate cutting quality gradually
It improves.
The flank of ceramic cutter tooth I is equipped with several comb teeth slots of the cutting edge perpendicular to the ceramics cutter tooth I, Stupalox
The flank of tooth II is equipped with several comb teeth slots of the cutting edge perpendicular to the ceramics cutter tooth II, the flank of ceramic cutter tooth III
Be equipped with several comb teeth slots of the cutting edge perpendicular to the ceramics cutter tooth III, the flank of ceramic cutter tooth IV equipped with perpendicular to
Several comb teeth slots of the cutting edge of the ceramics cutter tooth IV；
Comb teeth slot in the flank of two neighboring ceramics cutter tooth is in interlaced setting.The beneficial effect of structure design
It is: reduces friction and the cutting force of flank and cutting plane, the setting of comb teeth slot facilitates cutting off for lumber fibre, no
The influence that will receive machine direction avoids lumber fibre from scooping up (fluffing), especially when cutting timber knot position, Ke Yiti
The cutting quality of high cutting plane.
Preferably, ceramic cutter tooth I is formed by central angle, ceramic cutter tooth II and ceramic cutter tooth III with ceramic cutter tooth II
Being formed by central angle, ceramic cutter tooth III and ceramic cutter tooth IV and being formed by central angle is respectively 13 °, 10 °, 7 °.The structure is set
The beneficial effect of meter is: in same spiral ceramics cutter tooth group: ceramic cutter tooth I another spiral ceramics cutter tooth group adjacent thereto
Adjacent ceramic cutter tooth IV be formed by central angle maximum, thus the cutting of the ceramic cutter tooth I in each spiral ceramics cutter tooth group
Amount is maximum, and then between the ceramic cutter tooth I in same spiral ceramics cutter tooth group and ceramic cutter tooth II, ceramic cutter tooth II and ceramics
It is formed by central angle reduction between cutter tooth III, between ceramic cutter tooth III and ceramic cutter tooth IV, realizes same spiral Stupalox
The cutting output of tooth group is to be gradually reduced, and ensure that the raising of cutting quality.
