Description

A kind of high temperature alloy milling rose cutter

Technical field

The present invention relates to a kind of cutters of field of machining, and in particular to a kind of high temperature alloy milling blade type is special Milling cutter.

Background technology

High temperature alloy possesses the performances such as good heat fatigue, thermostabilization, heat is strong, can bear complex stress under high temperature environment And work normally, it is widely used in aviation, the difficult processing problems of high-temperature alloy material are the difficult points of currently manufactured industry, are cut That there are cutting temperatures during cutting is high, cutting force is big, tool wear is serious, machining accuracy and machined surface quality are undesirable The problems such as, conventional knives chip rose cutter flank is continuous plane, flank be processed after workpiece surface frictional force Greatly, a large amount of cutting heats are generated with workpiece contact zone in cutting edge and flank, and is difficult to spread, heat builds up generation High temperature, and milling cutter chip space is smaller, heat dispersal situations are poor, long lasting for high temperature and pressure effect under, cause cutting edge With being seriously worn for flank, workpiece machining surface quality and cutter life are directly influenced.

Research shows that Non-smooth surface grain surface has anti-attrition effect, such as in nature, some insects, snake, pangolin, shark The body surface of the animals such as fish is not completely smooth, and there are the micro-structure units of certain geometrical shape randomly or regularly The certain positions of body surface are distributed in, the surface topography of these Non-smooth surface features has frictional resistance more smaller than smooth surface, can It is effective to reduce contact wear.

Invention content

For in above-mentioned background technology when milling high temperature alloy space flight metal material there are the problem of, present invention aims at A kind of high temperature alloy milling rose cutter is provided, having reduces cutting temperature, reduce cutting force, is wear-resistant, improving processing table Face quality, the excellent cutting ability of tool life.

To achieve the above object, the present invention provides the following technical solutions：A kind of high temperature alloy milling rose cutter, it is wrapped It includes by cutting edge one（4）With cutting edge two（10）The cutter head of composition, and the rake face one that is connected respectively with the cutting edge（1）, the One flank（2）, the second flank（3）, rake face two（12）, major first flank（9）, the second flank（8）, feature exists In：The major first flank（2）And major first flank（9）To be equipped with cross grain structure（17）Surface.

The cross grain structure（17）0.08~0.11mm of width, grain angle are 30~45 °, and away from cutting edge distance For 0.06~0.12mm, the groove between cross grain（16）Width is 0.05~0.08mm, 0.045~0.065mm of depth.

The rake face one（1）With first groove face（5）Constitute the first hook-type chip pocket（11）, rake face two（12）With Second groove face（13）Constitute second hook shape chip pocket（15）.

The cutter head upper surface（7）The lower surface and（14）Between be machined with trip bolt hole（6）, cutter head passes through clamp screw Nail hole（6）It is connect with knife bar.

Compared with prior art, the beneficial effects of the invention are as follows.

The present invention is equipped with cross grain structure in cutter flank, and tool surface texture can reduce contact surface when friction Product reduces friction coefficient when Tool in Cutting, also reduces the heat generated in friction process, while also increasing tool surface Heat dissipation area, cutting fluid can be allowed to take away more heats, compared to the cutter of texture-free, enter cutter table when there is lubricating fluid Self-lubricating texture cutter will be formed when the texture of face, can increase the self-lubricating property of cutter, and can reduce cutter friction Abrasion, in process of friction and wear, adhesion effectively reduces textured cutter, improves the wear-resisting property of cutter so that knife It is more steady brisk to have the process that switches in and out, and effectively reduces cutting force, cutting temperature, tool wear, cutter and work Friction coefficient between part improves processing efficiency to a certain extent, and remained on surface height value smaller, workpiece surface quality is more preferably.

The present invention devises hook-type chip pocket and increases chip space, increases cutter heat transfer area, reduces rake face heat collection In, while heat transfer can be accelerated, the heat dissipation performance of cutter is enhanced, the temperature of rake face is effectively reduced.

The present invention devises double flank structures, under the premise of ensureing edge strength, improve cutter with it is machined Friction between surface.

Specific implementation mode

To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool Body embodiment is described in detail.

- 4 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of high temperature alloy milling rose cutter, it includes By cutting edge one（4）With cutting edge two（10）The cutter head of composition, and the rake face one that is connected respectively with the cutting edge（1）, first Flank（2）, the second flank（3）, rake face two（12）, major first flank（9）, the second flank（8）, major first flank （2）And major first flank（9）To be equipped with cross grain structure（17）Surface, rake face one（1）With first groove face（5）Constitute the One hook-type chip pocket（11）, rake face two（12）With second groove face（13）Constitute second hook shape chip pocket（15）, the knife Head upper surface（7）The lower surface and（14）Between be machined with trip bolt hole（6）, cutter head passes through set screw hole（6）Connect with knife bar It connects.

First hook-type chip pocket（11）With second hook shape chip pocket（15）Chip space is increased, cutter heat-transfer area is increased Product reduces rake face heat and concentrates, while can accelerate heat transfer, enhances the heat dissipation performance of cutter, effectively reduces preceding knife The temperature in face.

In Tool in Cutting workpiece, can be in contact between the fresh finished surface and flank of workpiece, phase mutual friction, and And the friction situation between cutter flank and workpiece surface and CONTACT WITH FRICTION length, directly affect the matter of machined surface Amount, cutter wear of the tool flank, cutter life and productivity can be effective when the flank of cutter is equipped with texture structure Friction coefficient when Tool in Cutting is reduced, cross grain structure is machined in flank（17）Width 0.1mm, grain angle are 45 °, and be 0.08mm away from cutting edge distance, groove between cross grain（16）Width is 0.06mm, depth 0.05mm, the texture structure It can be completed by laser processing or minute abrasive spraying technique, tool surface texture can reduce contact area when friction, The heat generated in friction process is reduced, while also increasing the heat dissipation area of tool surface, cutting fluid can be allowed to take away more More heats will form self-lubricating texture cutter when there is lubricating fluid to enter tool surface texture, can increase cutter oneself Greasy property, and cutter fretting wear can be reduced, in process of friction and wear, adhesion effectively subtracts textured cutter It is few, improve the wear-resisting property of cutter so that it is more steady brisk that cutter switches in and out process, and for cutting force, cut The friction coefficient and tool wear cut between temperature, cutter and workpiece have good improvement, improve processing effect to a certain extent Rate, remained on surface height value smaller, workpiece surface quality is more preferably.

The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications It should be regarded as protection scope of the present invention.
