Abstract
The utility model relates to a blade capable of preventing generating built-up edges, which is characterized in that a front angle of the blade ranges from 25 degrees to 40 degrees, and a chip breaking inclined surface is additionally arranged at a position opposite to a front cutter surface. By utilizing a large blade front angle and additionally arranging the chip breaking surface, the blade can improve chip breaking, thereby effectively avoiding generating built-up edges, and increasing processing surface quality and processing efficiency.
Description
Technical field
The utility model relates to a kind of blade that is used for metal cutting, particularly a kind of cutting tip that can improve the workpiece crudy.
Technical background
During the Tool in Cutting metal, if the good toughness of workpiece material, the cutter chip removal is not smooth, cool off bad, the cutting just be easy to be deposited on the rake face of cutter, along with the cutting constantly carry out, the cutting of piling up on the rake face is more and more, up to growing up to a thing as knurl, Here it is built-up edge, we are also referred to as the knurl on " cold welding " usually.Built-up edge has just changed the original angle of cutter after producing, and makes chip removal not smooth on the one hand, causes the machined surface of smear metal scratch workpiece.On the other hand, when built-up edge is grown up behind certain Chengdu, the machined surface that it also can the scratch workpiece.Moreover the hardness of built-up edge substantially exceeded the hardness of workpiece material, grows up after to a certain degree when built-up edge, will come off the machined surface that the built-up edge that splits away off also can the scratch workpiece.The generation of built-up edge can destroy the roughness of machined surface in a word, and the scratch workpiece will be avoided the generation of built-up edge.
The machined field does not have the generation that good method prevents built-up edge to the material of good toughness such as cutting aluminium, steel at present.During as the cam shaft bush of certain company's processing diesel engine cylinder block, because lining is an aluminum, nearly 80%～85% cylinder block lining is because built-up edge produces line hinders, and has to get lining by hand, does over again again, had a strong impact on ordinary production.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of insert for metal cutting that can prevent effectively that built-up edge from producing, and improves workpiece crudy and working (machining) efficiency.
The utility model can prevent that the blade that built-up edge produces has following structure: the blade anterior angle is preferably 35 ° between 25 °～40 °, and is increasing a chip breaking inclined-plane with the rake face relative position.The angle of chip breaking inclined-plane and rake face is 60 °～90 °.
The blade anterior angle refers to the angle of blade and horizontal plane.The anterior angle of ordinary blade is about 0～15 °, and the chip removal poor effect increases after the blade anterior angle greatly, and blade is very sharp, and big anterior angle can be improved chip removal; Increase a chip breaking inclined-plane in the position relative, changed the flow direction of smear metal, accelerated the fracture of smear metal, help chip removal with rake face.Adopt technique scheme, experiment shows, can reduce the generation of built-up edge greatly, helps improving workpiece crudy and production efficiency.
Description of drawings
Fig. 1 can prevent a kind of concrete structure schematic diagram of the blade that built-up edge produces for the utility model;
Fig. 2 can prevent a kind of concrete structure front view of the blade that built-up edge produces for the utility model.
Among the figure: 1-blade rake face; 2-chip breaking inclined-plane; The 3-tool orthogonal rake.
The specific embodiment
Further specify structure and the result of use that the utility model can prevent the blade that built-up edge produces below in conjunction with accompanying drawing.
When using the utility model can prevent the blade of built-up edge generation, when the point of a knife cutting workpiece, the excess stock of cutting-out will flow backward along rake face 1, because the blade anterior angle is very big, blade is very sharp, cuts brisk; Simultaneously big anterior angle makes rake face 1 steepening, has accelerated the translational speed of smear metal, can be the very fast band of smear metal from rake face.When smear metal moves to inclined-plane 2, the moving direction of smear metal just is changed, smear metal this moment is produced distortion once more, inclined-plane 2 is oblique more, and the degree of chip deformation is big more, easy more generation plastic deformation, disconnected, crushed turnings when causing smear metal to become 2 by the long smear metal 1 time, improve the chip removal ability greatly, accelerated the transfer of smear metal heat, thereby can avoid the generation of built-up edge effectively.
Experiment shows, certain company is after having used this blade, and the line that causes because of built-up edge is hindered ratio and can be dropped to about 0.3%～1% by 80%～85%, and effect is very obvious.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
