Description
Technical Field
The invention relates to the field of metal cutting machining, in particular to an indexable milling blade for machining a side wall.
Background
In the field of metal cutting machining nowadays, the requirement on the machining precision of the side face of a part is higher and higher, and the machining precision of the side face is mainly embodied in two aspects, namely the surface finish of the side face and the vertical precision of the side face and a machine tool standard. The main cutting edge of the existing indexable insert for milling is formed by connecting a plurality of sections of curve edges which are bulged outwards relative to the central hole of the insert, each section of curve edge is formed by intersecting a plane where each section of curve edge is located and a cutting rotating cylindrical surface corresponding to each section of curve edge, and when the insert is arranged on a tool body with different cutting rotating radiuses, the cylindrical surface obtained by rotating at least one section of curve edge around the rotating axis of the tool body can be ensured to be superposed with the cutting rotating cylindrical surface forming the curve edge. The spiral cutting edge designed by the method can process good vertical side face precision and obtain good surface finish under rotary cutter bodies with different diameters.
However, such inserts also have the disadvantage that when the cutting edge is curved in multiple sections to fit rotating bodies of different diameters, it is inevitable that a part of the curve is out of fit. If there is a rotating body, when a curve near the main cutting angle is fitted to the diameter of the body, other curves will probably be outside the fit, and there will be a limit value for the depth of cut of each tool, and if the depth of cut of the tool exceeds this limit value, the more pronounced the flank contact marks will be, which will have some effect on the cutting efficiency of the tool. When other curve segments than the curve segment near the main cutting corner are fitted to the diameter of the cutter body, the curve segments are fitted deviating from the diameter of the cutter body, and when the limit of the depth of cut is exceeded, not only the machining efficiency is affected, but also the machining precision of the side wall of the part is reduced, and particularly the vertical precision in the range near the root where the side surface and the bottom surface intersect is greatly fluctuated.

The indexable milling insert for processing the side wall, which is disclosed by the embodiment of the invention, is prepared by preparing the insert main body 1, belongs to a process technology of powder metallurgy, and is formed by once pressing and molding metal powder through a precise die and then sintering and shrinking the metal powder in a vacuum high-temperature sintering furnace. The first major cutting edge 7 and the second major cutting edge 33 are formed by the upper top surface 2 and the side surface 5 of the insert body 1 extending and intersecting with each other in respective curvatures, and the major cutting edges are responsible for a major cutting task for metal in the side wall cutting process, and directly affect the cutting effect and the service life of the insert. Meanwhile, the first main cutting edge 7 and the second main cutting edge 33 are respectively fitted on the first cutting rotary cylindrical surface 13 with the diameter D and the second cutting rotary cylindrical surface 14 with the diameter D, and extend on the corresponding cutting rotary cylindrical surfaces in sequence, and D > D, namely, the designed spatial structures of the first main cutting edge 7 and the second main cutting edge 33 are different. When the rotary cutter bodies 15 with different diameters are designed, the rotary cutter body 15 in a fitting large diameter range selects the first main cutting edge 7 for fitting, and the rotary cutter body 15 in a fitting small diameter range selects the second main cutting edge 33 for fitting, so that the fitting precision of the blade and the rotary cutter body 15, the overall cutting performance of the cutter, and the vertical precision and the surface quality of the side surface in side wall machining are effectively improved.
The flat cutting edge 8 and the secondary cutting edge 9 are formed by extending and intersecting the upper top surface 2 and the end surface 4 of the insert body 1 according to respective curvatures, and the flat cutting edge 8 mainly plays a role in repairing a machined surface and improves the surface quality and the smoothness of the machined surface.

The main cutting corner 10 connects the main cutting edge which is subjected to radial cutting force and the wiper edge 8 which is subjected to axial cutting force, and is subjected to large cutting force and cutting heat during cutting. In addition, the flat cutting edge 8 and the auxiliary cutting edge 9 on the same side are smoothly connected through a concave curve to form a clearance 12, and the clearance 12 can reduce the contact length of the auxiliary cutting edge 9 and a workpiece during cutting machining of the blade body 1, reduce cutting resistance and facilitate discharge of chips.
As shown in fig. 2 and 3, the first major cutting edge 7 and the second major cutting edge 33 respectively extend smoothly from the corresponding major cutting corner 10 to the minor cutting corner 11 along a regular curve, and the height H of the major cutting corner 10 relative to the lower bottom surface 3 is greater than the height H of the minor cutting corner 11 relative to the lower bottom surface 3. The first main cutting edge 7 and the second main cutting edge 33 each comprise a first cutting curve 16, a second cutting curve 17, a third cutting curve 18, a fourth cutting curve 19 and a fifth cutting curve 20 which are smoothly connected in this order, the first cutting curve 16 connects the main cutting angle 10, the fifth cutting curve 20 connects the minor cutting angle 11, the first cutting curve 16 forms a first inclination angle a with the bottom surface 3, the third cutting curve 18 forms a second inclination angle b with the bottom surface 3, the fifth cutting curve 20 forms a third inclination angle c with the bottom surface 3, wherein c is greater than or equal to 0 DEG and less than a and less than or equal to b and less than or equal to 10 deg.
The main cutting edge according to the above embodiment of the present invention, which extends obliquely from the main cutting corner 10 at a higher position to the minor cutting corner 11 at a lower position, includes five smoothly connected cutting curves in sequence, wherein the first cutting curve 16 forms a first inclination angle a with the bottom surface 3, the third cutting curve 18 forms a second inclination angle b with the bottom surface 3, and the fifth cutting curve 20 forms a third inclination angle c with the bottom surface 3, and 0 ° < c < a < b < 10 °, such that the cutting curves on the main cutting edge form continuously varying inclination angles, and the first cutting curve 16 connecting the main cutting corner 10 has a smaller first inclination angle a, to enhance the strength of the entire insert body 1 near the main cutting corner 10. The whole cutting curve flows out towards the preset direction through the positive and continuously changing inclination angle, and meanwhile, the cutting resultant force borne by the main cutting angle 10 can be effectively dispersed, the cutting pressure of the main cutting edge is reduced, and the cutting process is lighter and faster.
The fifth cutting curve 20 is arranged parallel to the lower bottom surface 3, that is, the third inclination angle c is 0 °, and the length k of the fifth cutting curve 20 is greater than or equal to 0.6 mm. As shown in fig. 6, in the grinding process of the lower bottom surface 3 of the blade body 1, each grid of the grinding material disc 21 is provided with two protrusions 22 corresponding to the fifth cutting curves 20 of the main cutting edge, and the specially-made grinding material disc 21 is used for grinding and positioning by matching the protrusions 22 with the smoothing edge 8 in the grinding process, so that the difference between the highest point and the lowest point of the main cutting edge can be ensured to be minimum. In addition, in the quality inspection program of the blade, as shown in fig. 7, since the fifth cutting curve 20 of the main cutting edge is a horizontal curve after the blade is horizontally arranged, the probe 23 of the height gauge can easily detect the lowest point of the blade in the manual detection process of the blade, which not only can effectively control the dimensional accuracy of the product, but also can alleviate the fluctuation of the main cutting edge of the blade.
Wherein the side surface 5 comprises a first rear corner surface 24, a second rear corner surface 25 and a third rear corner surface 26, the first rear corner surface 24 is in contact with the upper top surface 2, the third rear corner surface 26 is in contact with the lower bottom surface 3, and the first rear corner surface 24 and the third rear corner surface 26 are transitionally connected by the second rear corner surface 25. The first rear angle surface 24 and the central axis of the central hole 6 form a first rear angle e; the second rear angle surface 25 and the central axis of the central hole 6 form a second rear angle f, and the third rear angle surface 26 and the central axis of the central hole 6 form a third rear angle g. The first relief angle e gradually increases along the direction from the main cutting edge 10 to the minor cutting edge 11 of the corresponding first main cutting edge 7 or second main cutting edge 33, the second relief angle f varies with the first relief angle e, and the third relief angle g is a constant relief angle.
The side surface 5 of the insert body 1 according to the above embodiment of the present invention is provided with a first relief surface 24, a second relief surface 25 and a third relief surface 26 in sequence from the upper top surface 2 to the lower bottom surface 3, wherein the first relief surface 24 forms a first relief angle e with the central axis, and the angle along the main cutting edge increases gradually from the main cutting corner 10 to the minor cutting corner 11. Because the cutting force born by the blade body 1 at the part close to the main cutting corner 10 is larger, the cutting abrasion is also serious, and the smaller first relief angle e is set at the position of the main cutting corner 10 and gradually increases and transits towards the auxiliary cutting corner 11, so that the cutting edge is firmer, and the durability of the blade is improved. The first relief angle e is gradually increased from the main cutting angle 10 to the sub-cutting angle 11, the second relief angle f is changed according to the change of the first relief angle e to perform smooth connection and transition, and the third relief angle g is set at a constant angle so that when the insert is mounted on the rotary cutter body 15 at a certain angle, the portion of the third relief surface 26 close to the lower bottom surface 3 of the insert body 1 does not interfere with the machining surface.
The assembly mode of the invention is as shown in fig. 8 and 9, a locking screw 27 compresses an insert body 1 in a cutter groove 28 in a rotary cutter body 15 in an eccentric mode, the locking screw 27 is tightly matched with a threaded hole 29 in the cutter groove 28, wherein a reference surface of the insert body 1 is attached to a first positioning base surface 30 in the cutter groove 28, a third rear corner surface 26 is attached to a second positioning base surface 31 in the cutter groove 28, a lower bottom surface 3 is attached to a third positioning base surface 32 in the cutter groove 28, and the rotary cutter body 15 is installed on a machine tool through a tool system for cutting. When designing the rotary cutter body 15 having a small diameter range, fitting is performed by fitting the second major cutting edge 33 having a small diameter, and when designing the rotary cutter body 15 having a large diameter range, fitting is performed by fitting the first major cutting edge 7 having a large diameter, and therefore, it is necessary to pay attention to the mounting direction when mounting the insert body 1. The insert body 1 is provided with a recognition point 32, which is mounted in the direction of the recognition point 32 when the rotary cutter body 15 is mounted, and the recognition point 32 is located close to the cutting plane in the small diameter fitting range and the recognition point 32 is located far from the cutting plane in the large diameter fitting range. In order to realize high-precision machining, the fitting diameter range selected by the blade with the small size generally cannot be large, and the expected purpose cannot be achieved if the overall precision of the cutting machining exceeds the range.
The embodiment of the invention also provides the preferable values of all the parameters of the blade: h is 3.5mm, H is 3.42mm, the first inclination angle a is 2 °, the second inclination angle b is 9 °, the third inclination angle c is 0 °, the length k of the fifth cutting curve 20 is 1.2mm, the diameter D of the first cutting rotating cylindrical surface 13 is 50mm, the diameter D of the second cutting rotating cylindrical surface 14 is 25mm, the minimum value of the first clearance angle e is 10 °, the maximum value is 18 °, and the third clearance angle g is 11 °.
