Description
Technical field
The utility model is related to a kind of turning inserts in machining field, and in particular to a kind of stainless steel semifinishing is special
Use turning insert.
Background technology
Stainless steel material has strong resistance to corrosion strong, high temperature resistant and low temperature tolerance ability, intensity and hardness all bigger, can
Plasticity is preferable, and many excellent performances such as surface finishing are widely used in various fields.But stainless steel material process
In there is many problems.Because there is stainless steel preferable plasticity, the generated chip of when cutting to be not easily broken, easily bond,
It is thus susceptible to processing hardening phenomenon, with the lengthening of cutting time, hardened layer can be accumulated constantly, and cutting force also can be therewith
Constantly increase.The increase of stainless steel hardness and cutting force can cause the friction between blade and workpiece to aggravate, and when cutting is produced
Heat can increase therewith.The heat conductivility of stainless steel is not fine, and heat increase can cause blade and workpiece temperature to increase, no
But it is easy to generate built-up edge on rake face, reduces the processing quality of workpiece machined surface, and it is possible that glue knife
Phenomenon.Blade temperature increases the abrasion that can aggravate blade, reduces the service life of blade.
Invention content
The utility model be directed to the chip that often occurs during stainless steel cutting at present be not easily broken, cutting force compared with
Greatly, the problems such as friction between blade and workpiece is larger, cutting temperature is higher, radiating condition is poor, blade abrasion is serious, viscous knife,
A kind of stainless steel semifinishing special-purpose vehicle blade is provided.
The utility model in order to achieve the above object, adopts the technical scheme that：The turning insert of the utility model is diamond shape
The four edges of body, rhombogen are linear cutting edge, and it is nose angle, four straight lines that acute angle is formed by between two linear cutting edges
It is rake face and flank that the inside and downside of cutting edge, which are respectively equipped with inclined plane, and rake face defines the recessed of diamond shape
Slot.Positioned at trip bolt hole of the rhombogen center position equipped with cylinder, designed around knife face trip bolt hole on blade
The diamond shape protrusion for the four sides bending being aligned with its center, is located at position of tool tip in diamond groove and devises clavate knife
Sharp reinforced structure, it is the convex of triangle that the rake face per side is designed with 11 equally distributed sections with diamond groove junction
It rises, the groove formed between rake face and the curved edges of diamond shape protrusion is chip space.
The utility model has the beneficial effects that：
1, using linear cutting edge, the cutting resistance that when cutting generates is smaller, and cutting stability is relatively good, and processing generates
Burr it is fewer, part machined surface precision can be improved；And cutting edge manufacture is easy, and grinding is more convenient.
2, the upper diamond shape protrusion that a four edges bending is devised in middle position of knife face on blade, can increase knife
The intensity of body, effective heat dissipation area of knife face in increase, improves cutting-tool's used life.
3, the angular dimension of blade relief is 8 °, and shape has a certain degree between flank and workpiece machined surface, this
Sample in cutting can to avoid them between be in direct contact, can reduce friction of the flank to machined surface, improve plus
Work precision reduces the temperature of blade.
4, it is located in diamond groove at position of tool tip and is designed with clavate point of a knife reinforced structure, it can increases point of a knife
Intensity, play a protective role to point of a knife；In cutting, which can play the role of assisting chip breaking, can be preferable
Ground controls chip curling, chip outflow and chip breaking process, avoids blade caused by due to chip is wrapped on blade and shakes
Dynamic and blade heating problem.
5, it is designed with the protrusion that 11 sections are triangle on each rake face, the chip that fractures can be played the role of；This
A little protrusions can also reduce the contact area between chip and blade, friction when to reduce chip sliding between blade,
The local pyrexia amount for reducing blade, plays a protective role to blade；These protrusions have certain lead to the outflow of chip simultaneously
To effect.
6, the groove formed between the curl and rake face of diamond shape protrusion is chip space, and there are preferable appearance bits and chip removal to make
With the friction between chip and rake face can be reduced；When using cutting fluid, chip space, which also has, accommodates certain cutting
The effect of liquid, the heat generated when not only cutting fluid can be made preferably to take away machining reduce the temperature of blade, Er Qieke
To enhance the lubricant effect of cutting fluid.
