Abstract
The utility model discloses a smart becomes sword, including tool bit and cutter arbor, be equipped with the cutting edge on the tool bit, the cutting edge includes main cutting edge and the chamfer cutting edge that meets with main cutting edge, and this chamfer cutting edge comprises the crossing knife face behind chamfer rake face and the chamfer, main cutting edge comprises the crossing knife face behind main rake face and the main rake face, and is equipped with the chip groove between two cutting edges, main rake face and chamfer rake face are the groove wall face of chip groove, its characterized in that: the chamfer cutting edge is formed by intersecting the correction surface and the chamfer rear cutter surface, and the correction surface and an adjacent surface intersect to form a correction edge. Therefore, the trend of the scrap iron is changed by the correcting blade during scrap removal, and the problem that the scrap iron is coiled and wound on a cutter is solved.
Description
Technical Field
The utility model relates to a smart shaping sword.
Background
The finish forming cutter is generally used for turning the surface of a hole wall smooth after reaming, but under the condition that a processed hole is deeper and the cutter has multiple steps, the scrap iron amount discharged during processing of the finish forming cutter is large, and the scrap iron is long, difficult to break and easy to curl up and wind on the cutter, so that the processing quality is influenced, and therefore improvement aiming at the problems is needed.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a precision forming knife.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a smart shaping sword, includes tool bit and cutter arbor, be equipped with the cutting edge on the tool bit, the cutting edge includes main cutting edge and the chamfer cutting edge that meets with main cutting edge, and this chamfer cutting edge comprises the crossing knife face behind chamfer rake face and the chamfer, main cutting edge is crossed by main rake face and is constituted, and is equipped with the chip groove between two cutting edges, main rake face and chamfer rake face are the groove wall face of chip groove, its characterized in that: the chamfer front cutter face is provided with a concave correction face, the chamfer cutting edge is formed by intersecting the correction face and the chamfer rear cutter face, and the correction face and an adjacent face intersect to form a correction edge.
The correction surface is parallel to the central axis of the cutter head.
The utility model has the advantages that: be equipped with the correction face of concavity on the knife face before the chamfer, the correction face intersects with an looks proximal surface and constitutes the correction sword, thus has changed the shape of iron fillings through the correction sword when the chip removal to thereby avoided iron fillings to beat the problem of book winding cutter.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a perspective view of the present invention;
fig. 2 is a partially enlarged view at a of fig. 1.
Detailed Description
Referring to fig. 1 and 2, the utility model discloses a precision forming cutter, which comprises a cutter head and a cutter bar, wherein the cutter head is provided with a cutting edge, the cutting edge comprises a main cutting edge 1 and a chamfer cutting edge 2 connected with the main cutting edge 1, the chamfer cutting edge 2 is formed by intersecting a chamfer front cutter face and a chamfer rear cutter face 22, the main cutting edge 1 is formed by intersecting a main front cutter face 11 and a main rear cutter face 12, a chip groove 3 is arranged between the two cutting edges, the main front cutter face 11 and the chamfer front cutter face are both groove wall faces of the chip groove 3, the chamfer front cutter face is provided with a concave correction face 4, the part of the chamfer front cutter face adjacent to the chamfer rear cutter face 22 is completely concave in the application to form a correction face 4, the correction face 4 is parallel to the central axis of the cutter head, the radial angle and the axial angle of the correction face 4 are both 0 degree, and the chamfer cutting edge 2 is formed by intersecting the correction face 4 and, and this correction face 4 intersects with an adjacent surface and constitutes correction sword 5, because our cutter is cascaded reaming many times gradually, therefore have several sections main cutting edge 1 of different footpaths, in this application, main cutting edge 1 has three sections and arranges according to the distance with the tool bit top and divide into, including first main cutting edge, second main cutting edge and third main cutting edge and first chamfer cutting edge, second chamfer cutting edge and third chamfer cutting edge, we have all set up correction face 4 in first chamfer cutting edge, second chamfer cutting edge department, the length of the correction sword 5 that two above-mentioned correction faces 4 constitute respectively: 0.21cm and 0.1cm, the adjacent surface in this application is the main back knife face 12 of the next main cutting edge 1 adjacent to this correction face 4, through the extrusion correction of the iron fillings of correction sword 5, not only changed the shape of iron fillings, the discharge mode of iron fillings also becomes the straight line chip of appearing moreover to the winding to the cutter has been avoided.
The above detailed description is made on the precision forming knife provided by the embodiment of the present invention, and the detailed embodiments are applied herein to explain the principle and the implementation manner of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
Claims (2)
1. The utility model provides a smart shaping sword, includes tool bit and cutter arbor, be equipped with the cutting edge on the tool bit, the cutting edge includes main cutting edge and the chamfer cutting edge that meets with main cutting edge, and this chamfer cutting edge comprises the crossing knife face behind chamfer rake face and the chamfer, main cutting edge is crossed by main rake face and is constituted, and is equipped with the chip groove between two cutting edges, main rake face and chamfer rake face are the groove wall face of chip groove, its characterized in that: the chamfer cutting edge is formed by intersecting the correction surface and the chamfer rear cutter surface, and the correction surface and an adjacent surface intersect to form a correction edge.
2. The finish forming knife of claim 1, wherein: the correction surface is parallel to the central axis of the cutter head.
