Abstract
The utility model belongs to the technical field of superhard cutter and specifically relates to a strong fix chip -breaker superhard insert, including 80 corner rhombus cutter blade bodies, the cutting edge department of blade body is provided with the chip -breaker, and the chip -breaker is the V font on the blade body, and the contained angle of V font chip -breaker is greater than the apex angle of blade body main cutting edge department, and the center department of blade body is provided with the fixed slot. Compared with the prior art, the utility model discloses under certain condition in the aspect of the effect of realization, can exert excellent chip -breaking performance, improve cutter life and production efficiency, improve the processing environment, protection workpiece surface quality improves workpiece surface smooth finish, set up the fixed slot on the blade body, prevent on the one hand the blade when the atress is uneven from the cutter arbor the departure, on the other hand can prevent also that the blade from turning over to give birth to to deflect, improves the surface machining quality of work piece, to operating personnel's safety in production, also play an active role.
Description
Technical field
The utility model belongs to superhard cutter technical field, is specially a kind of firm location superhard blade of chip breaker.
Background technology
In prior art, for chip chip breaking, common mode arranges chip breaker exactly on blade, the existing blade with chip breaker PCBN, the chip process of the most applicable moulding material material processing, the chip breaker held is when depth of cut is less than 0.3mm, it is possible to play excellent chip handling property. But in the roughing stage, often with the increase of depth of cut, chip is frangibility not, affects workpiece surface processing quality, also the safety of operator is had impact, and chip also needs to process manually, and waste of manpower, affects working efficiency simultaneously.
For the roughing of moulding material material, cutting speed increases, and chip basic limit shape reduces, and volume bits diameter increases, chip breaking deleterious; When depth of cut increases, chip difficulty. At present, what the roughing of moulding material material generally adopted is the PCBN cutter of alloy cutter, coated cutting tool and not band chip breaker, chip mostly is continuous chip, to the serious wear of blade, cause the work-ing life of roughing stage blade shorter, increasing blade exchange number of times, relative just reduces production efficiency.
Practical novel content
The technical problems to be solved in the utility model is: what the existing roughing stage adopted is alloy cutter, coated cutting tool and PCBN not band chip breaker cutter, wear resistance is not good, so that production efficiency is low, for solving the problem, it is provided that a kind of firm location superhard blade of chip breaker.
The purpose of this utility model realizes in the following manner:
A kind of firm location superhard blade of chip breaker, comprise 80 ° of diamond shaped insert bodies, the cutting edge place of blade body is provided with chip breaker, chip breaker is V-shaped in blade body, the angle of V-shaped chip breaker is greater than the drift angle at blade body main cutting edge place, and the center of blade body is provided with pickup groove.
The cross section of chip breaker is V-shaped, and angle is 120-150 degree.
The height at the cutting edge place of blade body is lower than the height of blade body.
The degree of depth of chip breaker is 0.25-0.4mm.
The useful length of chip breaker is 3-6mm.
Blade body is provided with negative chamfered edge.
The angle of V-shaped chip breaker is 90-110 degree.
The cross section of pickup groove is long strip shape, circle, rectangle or trilateral.
Relative to prior art, the effect aspect that the utility model realizes is under certain conditions, it is possible to play excellent chip-breaking performance, it is to increase cutter life and production efficiency; Improve processing environment, protection workpiece surface quality, it is to increase workpiece surface finish; Blade body arranges pickup groove, prevents blade from flying when unbalance stress from knife bar on the one hand, on the other hand, it is possible to prevent the anti-raw deflection of blade, it is to increase the suface processing quality of workpiece, to the safety in production of operator, also play active effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 partial enlargement figure.
Fig. 3 is Figure 1A-A sectional view.
Wherein, 1 is blade body; 2 is chip breaker; 3 is negative chamfered edge; 4 is pickup groove.
Embodiment
As shown in Figure 1-Figure 3, a kind of firm location superhard blade of chip breaker, comprise 80 ° of diamond shaped insert bodies 1, the cutting edge place of blade body 1 is provided with chip breaker 2, and chip breaker 2 is in V-shaped in blade body 1, and the angle of V-shaped chip breaker 2 is greater than the drift angle at blade body 1 main cutting edge place, as shown in Figure 2, α is the angle of chip breaker, and α is 90-110 degree, can select 90 °, 95 °, 100 °, 105 °, 110 ° in practical application. The center of blade body 1 is provided with pickup groove 4.
The cross section of chip breaker 2 is V-shaped, angle is 120-150 degree, according to blade shapes and thickness, 120 °, 125 °, 130 °, 135 °, 140 °, 145 °, 150 ° can be selected, or other unlisted angles, Fig. 3 is the sectional view of blade body 1, and the β in figure is the cross section angle of chip breaker 2.
The height at the cutting edge place of blade body 1 is lower than the height of blade body 1, it is possible to effective increase depth of cut and chip breaking effect. The degree of depth of chip breaker 2 is 0.25-0.4mm, such as 0.25mm, 0.3mm, 0.35mm or 0.4mm.
The useful length of chip breaker 2 is 3-6mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, and the useful length of chip breaker 2 is relevant with the shape of blade body 1, it is possible to avoid workpiece surface when chip breaking, protection workpiece surface quality.
Blade body 1 is provided with negative chamfered edge 3.
The cross section of pickup groove 4 is long strip shape, circle, rectangle or trilateral, it is possible to thinking that multiple cross section is that the pickup groove 4 of long strip shape is distributed in blade body 1, the pickup groove 4 in Fig. 1 is circular. Blade arranges pickup groove 4, prevents blade to fly from knife bar, if adopting square or trilateral pickup groove, also there is the phenomenon preventing blade from deflecting and occur, it is to increase the suface processing quality of workpiece.
