Description
Technical field
The present invention relates to the metal cutting manufacture field, relate in particular to a kind of blade that is used for groove processing cutting.
Background technology
The location of groove processing blade above-below direction is realizing through the locating surface up and down of blade; The locating surface up and down of this blade is usually designed to protruding V-type face or recessed V-type face, cooperates with the cutter hub that is designed to corresponding recessed V-type locating surface or protruding V-type locating surface to be used to process various grooveds.This blade is made simple; Easy to use; Protruding V-type face and the locate mode that recessed V-type face contacts have increased effective contact area of blade locating surface, have strengthened the ability of blade at side and end face bearing load; The impact resistance that has promoted blade collapses scarce ability, the service life of assurance groove processing blade with anti-; In addition; The large tracts of land contact of blade locating surface can make blade when bearing bigger load; Small distortion only takes place in locating surface, effectively guarantees the uniformity of cutting tip dimensional accuracy in static and process, has improved the stability under the different operating modes of cutting tip.Because groove processing blade has above-mentioned advantage, this kind structure is widely used in the groove class process tool.
Though groove processing blade adopts the location structure of protruding V-type face and recessed V-type face to have many good qualities, and also has some problems.Groove processing blade is a carbide chip generally speaking, often when oversintering, can deform, in addition; Because detect the anchor clamps mismachining tolerance, detect error and and the existence of cutting tool rigging error, when making blade be assemblied on the cutter hub up and down locating surface be difficult to contact fully, simultaneously; Blade is when being held and in the working angles; The locating surface up and down of blade bears the bigger and complicated load of variation, and the locating surface up and down of blade is difficult to contact fully with the locating surface of cutter hub, thereby blade is in working angles; The locating surface up and down of blade and the location of cutter hub are in the edge line contact condition basically, or cutter hub contacts with the outstanding position of blade distortion.Blade and cutter hub are in line and contact and generally occur in the centre position and the marginal position of locating surface up and down; When the line contact is in the centre position of blade, blade will lose the locating effect of side surface direction, and blade is when side cutting; Blade is because clamping is unstable, can wear and tear fast or collapses scarce; When the line contact is in the edge of blade; The locating surface edge loading is excessive up and down for blade; And blade up and down between locating surface and the side wall thickness too small, the sideways shear stress of locating surface is excessive up and down for blade, as easy as rolling off a log cause blade up and down locating surface collapse scarce to side surface direction.When blade is out of shape when serious, the outstanding position of locating surface plays the role of positioning up and down, and the blade clamping is unstable, and blade is prone to collapse scarce during cutting, even possibly break away from cutter hub and flies out.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, and a kind of blade that is used for groove processing cutting that can adjust position location and angle, Stability Analysis of Structures, long service life automatically is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of blade that is used for groove processing cutting; Comprise locating surface, following locating surface, two end faces and two sides that connect upper and lower locating surface; The said locating surface of going up is provided with M the discontinuous positioning table of going up; Said locating surface down is provided with N discontinuous positioning table down, 2≤M≤10,2≤N≤10.
If be parallel to said two sides and be midplane to the equidistant plane of two sides; Distance between said two sides is D, and the said minimum range that goes up between positioning table and the adjacent side is L1, and the said minimum range that goes up between positioning table and the midplane is L1 '; Minimum range between said positioning table down and the adjacent side is L2; Minimum range between said positioning table down and the midplane is L2 ', 0.05D≤L1≤0.1D, 0.05D≤L1 '≤0.1D; 0.05D≤L2≤0.1D, 0.05D≤L2 '≤0.1D.
The said upward height of positioning table on last locating surface is H1,0.3L1≤H1≤0.5L1, and 0.3L1 '≤H1≤0.5L1 ', the height of said positioning table down on following locating surface is H2,0.3L2≤H2≤0.5L2,0.3L2 '≤H2≤0.5L2 '.
Angle between the last positioning table of said midplane both sides is α, and the angle between the following positioning table of said midplane both sides is β, 80 °≤α≤160 °, and 80 °≤β≤160 °.
The said positioning table of going up is symmetrical set along said midplane, and said positioning table down is symmetrical set along said midplane.
Compared with prior art, the invention has the advantages that:
1, the blade that is used for groove processing cutting of the present invention; Be respectively equipped with the last positioning table and the following positioning table of some on it on locating surface, the following locating surface; Through being set, upper and lower positioning table can effectively control blade above-below direction participation positioned area; Avoid blade to contact during cutting or contact with the centre position of cutter holder with the edge line of cutter holder; Improve the stability of blade in working angles, make blade have the function of automatic adjustment position location and orientation angle, and make blade accurate positioning, the accuracy of manufacture require low, easy to process; The quantity and the size of the upper and lower positioning table about the accurate design blade on the locating surface can suppress the contact area because of blade distortion minimizing blade and cutter hub, and the position stability, the raising blade that increase blade bear cutting force and shock proof ability; In addition, upper and lower positioning table is interrupted shape in the midplane both sides, and for the plane of grinding upper and lower positioning table provides possibility, and interrupted upper and lower positioning table reduced amount of grinding, reduced the grinding cost.
2, accurately design upper and lower location with and the distance of adjacent side, and the distance of upper and lower positioning table and midplane makes blade can adjust position location and orientation angle automatically; Through setting the distance between upper and lower positioning table and the side, make the line of blade contact when occurring in upper and lower location edge of table, can reduce the shear stress of the upper and lower locating surface of blade to side surface direction, effectively suppress upper and lower locating surface and collapse scarce; Through setting the distance of upper and lower positioning table and midplane; Can suppress the blade upper and lower to position line contact occur on the midplane; Guarantee that blade can transmit bigger cutting force on side surface direction, prevent that blade from wearing and tearing fast because of clamping is unstable or collapse scarce.
