Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a excircle shaping grooving cutter as shown in fig. 1-6, including interconnect's handle of a knife 1 and cutting part 2, cutting part is cylindrical, and the lateral wall has four blade locating surfaces, and the welding has the blade on the blade locating surface, blade quantity is 4, divide into two sets of, two sets of the blade is mutual interval central symmetry and sets up on the blade locating surface, and each set of the blade includes first blade 3 and second blade 11, first blade 3 and second blade 11 all have welding surface, rake face and terminal surface, it keeps away empty sword 4, left chamfer sword 5, the left side sword 6 of grooving, excircle sword 7, the right side sword 8 of grooving, right chamfer sword 9 and the second on the rake face of first blade 3 to have the first, and keep away empty sword 4, left chamfer sword 5, the left side sword 6 of grooving, excircle sword 7, the right side sword 8 of grooving, right chamfer sword 9 and the second, the perpendicular distance of left side sword 6 knife point and terminal surface of grooving is t;
the front tool face of the second blade 11 is provided with a first clearance edge 4 ', a left chamfer edge 5', a left side edge 6 'of a cutting groove, an outer circle edge 7', a right side edge 8 'of the cutting groove, a right chamfer edge 9' and a second clearance edge 10 ', the vertical distance between the tool tip of the left side edge 6' of the cutting groove and the end face is t ', and t' is greater than t.
Further, in the above technical solution, the intersection point of the left chamfer edge 5 and the left cutting edge 6 of the cutting groove in the first blade 3 and the intersection point of the right chamfer edge 9 and the right cutting edge 8 of the cutting groove are on the same horizontal plane on the longitudinal section;
