Further, it is described from front to back gradually overstriking structure since the middle position the junction of cutter head and knife handle to knife handle
It sets.
The present invention has following substantive distinguishing features outstanding and technological progress:
1, the present invention is led to due to extending to form from front to back gradually overstriking structure to shank section in the junction of cutter head and knife handle
Crossing this, gradually overstriking structure forms transition strut angle β, the gradually enhancing branch of overstriking structure cutter entirety from front to back from front to back
Support structure；Contact when the blade part pitch angle alpha of cutter head can mitigate incision to machined surface, formation prevent crushing knife and chip removal knot
Structure；The central spindle thickness S of cutter head forms enhancing cutter interior rigid structure to increase the hardness of cutter；The blade part length L of cutter head
To increase the rigidity of blade part, enhance cutter rigid structure when forming processing；Therefore it is able to solve the gas chamber air flue of the prior art
Port recess process tool is easy to happen when existing at processing concave corner and allows knife, breaking, influences the qualification rate and production effect of product
The problems such as rate and short service life；Knife, breaking will not be allowed when at processing concave corner, improve product qualification rate and
The substantive distinguishing features outstanding such as production efficiency and long service life and significant technological progress.
2, using the present invention, it can be achieved that gas chamber gas port processes fraction defective 0.36% → 0.1%；Behaviour's industry can effectively be saved
Take, and reduces cutter expense.It can reduce and not sow the time.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the specific embodiment of the invention 1.
Fig. 2 is the cutter head partial structural diagram of the specific embodiment of the invention 1.
Fig. 3 is the structural schematic diagram of the prior art.
Specific embodiment
The present invention will be further described below with reference to the drawings.
Specific embodiment 1:
- Fig. 2 referring to Fig.1, the present embodiment include cutter head 1 and knife handle 2, are prolonged in the junction of cutter head 1 and knife handle 2 to shank section
Stretch to form from front to back gradually overstriking structure, by this from front to back gradually overstriking structure formed transition strut angle β, it is described from front to back
The gradually enhancing support construction of overstriking structure cutter entirety；The blade part pitch angle alpha of cutter head 1 is 35 ° ± 1 °, with when mitigation incision pairs
The contact of machined surface, formation prevent crushing knife and chip removal structure；The central spindle thickness S of cutter head 1 is 2.6mm-3.0mm, to increase cutter
Hardness, formed enhancing cutter interior rigid structure；The blade part length L of cutter head 1 is 7.0mm ± 0.1mm, to increase blade part
Rigidity, formed processing when enhance cutter rigid structure.
In the present embodiment:
Knife handle 2 has cylindrical-shaped structure, and the diameter of the cylindrical-shaped structure is φ 12, to increase shank section diameter, improve
Cutter integral rigidity.
Coniform gradually overstriking structure is formed in the junction of cutter head 1 and knife handle 2, makes to increase strut angle branch at 2 stress of knife handle
Support, forms the reinforcement structure of easily broken cutter position.
The front of knife handle 2 is in coniform, rear portion is cylindrical.
It is described from front to back gradually overstriking structure since the medium position the junction of cutter head 1 and knife handle 2 to knife handle 2.
By the production practices of applicant, it is short that cutting-tool's used life of the existing technology can solve using the present invention
The problem of.The present invention is applicant by analysis decomposition status cutter structure mode and processing content, quality requirements, is ground again
The cutter for studying carefully exploitation can achieve and cut down cutter consumed cost, improve production efficiency, cut down bad, realization improvement output effect
Maximized purpose.
Applicant proves that the gas chamber gas port Pocket Machining cutter of the prior art actually uses the longevity by production practices
Life only reaches the 11% of setting value, and the bad middle breaking number of in September, 2016 in January, -2017 cutter is 36 times, and cutter is bad disconnected
Knife Zhan always abnormal breaking 80%；It is bad that Pocket Machining bad (predominantly 4.3 ± 0.1mm of groove height size) accounts for overall dimensions
36%.The recessing tool cutter rigidity now used is insufficient, causes tool sharpening abnormal, the bad generation of quality.Main cause are as follows:
(1) tool shank is meticulous, without strut angle, causes to be easy to appear breaking phenomenon when processing stress, and occur knife handle with cut
Cut the transition position position at position；(2) cutter central spindle thickness is thin, only 2.6mm, is easy to appear breaking；(3) opposite cutter central spindle
Line, spiral angle is less than normal, contacts excessive when cutting with machined surface, and cutting force increases, and occurs allowing knife, erosion knife situation.(4) groove arrives
The distance of sealing surface, i.e. 4.3 ± 0.1mm of groove height size, since casting skin residual can occur for Pocket Machining face to increase
Material meat is thick, causes Tool in Cutting stress excessive.And groove is machined surface on one side, another side is non-processing face, and cutting stress is not
Processing, which occurs, for equilibrium allows knife, leads to the bad generation of dimensioned.
After applying the present invention, there is following features and effect: (1) increasing shank section diameter and newly-increased 10 ° of cutter strut angle.
After tool shank increases, cutter integral rigidity can be improved；Increase strut angle support in knife handle and cutting junction, makes to be easy breaking
Position strengthened；(2) increase helix angle, be increased to 35 ° ± 1 ° by original 30 ° ± 1 °.To adding when mitigating incision
The contact in work face avoids cutting force when feed excessive, causes crushing knife, while the chip removal performance of cutter can be improved；(3) knife is thickeied
Has central spindle thickness.Maximum central spindle thickness increases to 3.0mm, enhancing cutter interior rigidity by 2.6mm.(4) shorten edge length, it is long
Degree shorten to 7mm by 10mm, while guarantee meets process requirements, improves rigidity when tool sharpening.
