Referring to fig. 1 and fig. 2, fig. 1 is a schematic perspective view of a finishing smoothing tool 10 according to an embodiment of the present invention, and fig. 2 is a schematic front view of the finishing smoothing tool 10. To achieve at least one of the advantages described or other advantages, an embodiment of the present invention provides a finishing smoothing tool 10. As shown in the figures, the finishing trowel 10 may include a blade body 20.
The insert body 20 is rectangular and has six locating surfaces. The six positioning surfaces are defined as an upper positioning surface 21, a lower positioning surface, a left positioning surface, a right positioning surface 22, a front positioning surface 23, and a rear positioning surface, i.e., the upper, lower, front, rear, left, and right surfaces of the rectangular insert body 20 in the drawing. A transition surface 24 is present between the left and right ends of the upper positioning surface 21 and the left and right positioning surfaces 22, respectively, i.e. a transition surface 24 is present between the left end of the upper positioning surface 21 and the left positioning surface, and a transition surface 24 is present between the right end of the upper positioning surface 21 and the right positioning surface 22. A wiper flank surface 25 is present between the front and rear ends of the upper positioning surface 21 and the front and rear positioning surfaces 23 and 23, respectively, i.e. a wiper flank surface 25 is present between the front end of the upper positioning surface 21 and the front positioning surface 23 and a wiper flank surface 25 is present between the rear end of the upper positioning surface 21 and the rear positioning surface.
A cutting edge 30 is defined by the intersection of the wiper flank 25, the transition surface 24, the left and right locating surfaces 22 and the front locating surface 23. Specifically, the cutting edge 30 includes a transition cutting edge 31, a wiper edge 32, and a main cutting edge 33. The two ends of the transition cutting edge 31 are connected with the flat cutting edge 32 and the main cutting edge 33 respectively. The transition cutting edge 31 is located at the intersection of the transition surface 24 and the front positioning surface 23 (i.e., the side of the transition surface 24 close to the front positioning surface 23), the wiper edge 32 is located at the intersection of the wiper edge flank surface 25 and the front positioning surface 23 (i.e., the side of the wiper edge flank surface 25 close to the front positioning surface 23), the main cutting edge 33 is located at the intersection of the left positioning surface and the front positioning surface 23 (i.e., the side of the left positioning surface close to the front positioning surface 23), and the main cutting edge 33 is located at the intersection of the right positioning surface 22 and the front positioning surface 23 (i.e., the side of the right positioning surface 22 close to the front positioning surface 23).
In some embodiments, the transition surface 24 may be a radiused transition surface or a beveled transition surface, which may be understood as a chamfered transition.
In some embodiments, the wiper edge 32 is made up of a plurality of circular segments of different radii and may be symmetrically distributed along the centerline. As shown in fig. 2, the wiper edge 32 may include at least a first arc segment 321, a second arc segment 322, and a third arc segment 323. The two ends of the second arc segment 322 are respectively connected with the first arc segment 321 and the third arc segment 323, the radius of the first arc segment 321 is the same as that of the third arc segment 323, and the radius of the first arc segment 321 is different from that of the second arc segment 322. The design of using the multi-section arc edge enables the smoothing edge 32 to be in a gradual cutting-in state when being processed, avoids the generation of large impact when the straight edge is cut in, and designs that the processing is more light and fast.
The wiper edge 32 is symmetrically disposed along a centerline (centerline refers to the centerline of the insert body 20 in fig. 2). Preferably, the second arc segment 322 is tangentially connected to the first arc segment 321, and the second arc segment 322 is tangentially connected to the third arc segment 323. The radius range of the second arc section 322 is 600-1000 mm, and the radius range of the first arc section 321 is 100-300 mm. The second arc section 322 mainly has a light-repairing function, so the arc radian is designed to be larger. The transverse length S of the second arc section 322 is in the range of 7-12 mm, which is larger than the length of the wiper 32 of the conventional face milling cutter, but the length of the wiper 32 cannot be designed to be too large, for example, if it is larger than 15mm, the machining load will be too large during machining. As described above, in order to shorten the length of the wiper edge 32, the first arc segment 321 and the third arc segment 323 on both the left and right sides are provided, so that the length of the wiper edge 32 can be shortened and the wiper edge can be mainly involved in cutting.
For example, in the finish machining, the cutting depth is substantially less than 1mm, most of the allowance is less than 0.5mm, the parts mainly participating in cutting are the first arc section 321, the third arc section 323 and the partial transition cutting edge 31, and in order to improve the machining precision, the height difference H between the highest point and the lowest point of the second arc section 322 is set to be 0.02-0.04 mm, that is, the second arc section 322 is higher than the first arc section 3210.02-0.04 mm, and preferably 0.03 mm.
In some embodiments, transition surfaces 24 are provided between the left and right ends of the lower locating surface and the left and right locating surfaces 22, respectively, to enhance machining accuracy.
In some embodiments, as shown in fig. 3 and 4, the wiper blade flank 25 extends backward from the wiper blade 32 at a preset angle α, and the angle of the wiper blade flank 25 is set such that the included angle between the wiper blade flank 25 and the workpiece is smaller during machining, thereby effectively suppressing tool chatter and workpiece springback caused by poor clamping rigidity of the workpiece during machining. However, it should be noted that when the preset angle α is too large, the first included angle β 1 and the second included angle β 2 between the wiper edge flank 25 and the workpiece are too small, which causes extrusion and friction between the wiper edge flank 25 and the workpiece, which causes the wear of the wiper edge flank 25 to be aggravated, and affects the life of the insert. Therefore, in combination with the axial installation angle of the wiper blade 32, the preset angle α is preferably in the range of 1.5 to 3 °, and more preferably 2 °.
As shown in fig. 5 and 6, the finishing smoothing tool 10 can be mounted on different types of tool bodies 41 and 42 for use. As shown in fig. 5, the same finishing smoothing tool 10 is used to perform the transverse and longitudinal mounting for the rough machining and the finishing in the tool body 41, respectively. As shown in fig. 6, the adjusting tool holder 45 may be used to axially adjust the finishing smoothing tool 10 mounted on the tool body 42, so as to further ensure the precision and improve the quality of the machined surface.
As shown in fig. 7 and 8, the finishing smoothing tool 10 can also be used with a conventional flush mounted face milling insert, and as the finishing smoothing tool 10 of the flush mounted face milling insert, the adjusting tool seat 45 can be used, and a special insert groove can be designed on the tool body 43 to mount the finishing smoothing tool 10. In order to ensure a better smoothing effect and prolong the service life of the smoothing blade, the axial radial position distribution of the finish machining smoothing tool 10 and the rough machining blade 50 needs to be adjusted, the inner shrinkage distance L1 of the radial position of the finish machining smoothing tool 10 relative to the rough machining blade 50 is 0.2-1 mm, and the relative protrusion distance L2 of the axial position is 0.02-0.04 mm.
In summary, an embodiment of the present invention provides a finishing smoothing tool 10, which can be a double-sided negative-type vertical mounted insert, wherein a positioning surface of the vertical mounted insert determining an axial height is a larger plane, and a manufacturing accuracy can be controlled within 0.01 mm. The insert body 20 is rectangular in shape so that the length of the wiper edge 32 is greatly extended, and the length and the projecting amount of the wiper edge 32 can be adjusted by arc sections of different diameters. That is, the length of the smoothing edge of the finishing smoothing tool 10 can meet the smoothing requirement, and the projecting amount of the smoothing edge 32 can be accurately controlled within a set range, so that the requirement of finish surface milling on the surface quality can be met. In addition, the vertical mounting of the negative type blade can increase the number of used blades, improve the economy of the wiper blade 32, and simultaneously, the vertical mounting structure ensures the strength of the wiper blade 32.
In addition, the value range of the 'to' includes the two end values per se, and the two end values belong to the protection range of the scheme.
