Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to the attached drawing 1, the machining die comprises a tool shank 1, wherein a conical tool guide portion 2 is arranged at the upper end portion of the tool shank 1, and an arc chamfer is arranged at the upper end portion of the tool guide portion 2.
The lower end of the cutter handle 1 is coaxially provided with a polished rod section 3, an appearance rough cutting section 4, an appearance finishing section 5, a punching finishing section 7 and a punching cutting rough cutting section 8, and the upper end part of the polished rod section is provided with a horizontally arranged cutter positioning surface 9; sand separating grooves 11 are respectively arranged between the polished rod section 3 and the shape rough section 4 and between the shape rough section 4 and the shape finishing section 5, and the cross section of each sand separating groove 11 is V-shaped or trapezoidal.
The punching fine trimming section 7 comprises a plurality of positioning steps 6 for positioning, and the punching cutting rough section 8 comprises a setting surface 10 arranged at the top end of the positioning steps 6 and a defined area 12 surrounding the setting surface 10. Fig. 2 is a schematic track diagram of the profile finishing section in fig. 1, wherein the profile finishing section 5 comprises a plurality of micro arcs which are connected with each other and symmetrically distributed along a horizontal axis, the micro arcs have a common circle center, and the radius increases with the increase of the central angle.
The defining area 12 has a predetermined height, and when the shaping surface 10 contacts the workpiece, the defining area 12 having the predetermined height can block the workpiece grinding powder within a certain range, and the height of the defining area 12 is 0.02mm to 1.3 mm. The delimited zone 12 comprises an annular flange 13 extending upwardly around the shaped face 10, the inner surface of the annular flange 13 being perpendicular to a tangent at the intersection of the shaped face 10. An opening with a large upper part and a small lower part is formed between the limiting area 12 and the shaping surface 10, and after the grinding process at the stage is finished, the limiting area 12 can be conveniently separated from the opening without being blocked by the limiting area 12. The smooth transition between the defined area 12 and the shaping surface 10 allows the workpiece edge to form a rounded edge during grinding. The device accurately defines the corresponding cutter structure level in the axial direction, various processing functions are integrated on the cutter, and the appearance finishing section of a special structure provides extremely high processing precision.
