Referring to Fig. 1, Fig. 1 is the structural schematic diagram of chamfering profile cutters in the utility model embodiment.The utility model A kind of chamfering profile cutters 100 that embodiment provides, including knife handle 10 and processing department 30, one end and the processing department 30 of knife handle 10 One end connection.
Specifically, knife handle 10 is cylindrical body, chamfering profile cutters 100 have rotation axis A, rotation axis A and knife handle 10 Axis be overlapped.When being processed using chamfering profile cutters 100, which is revolved around rotation axis A Turn.
The processing department 30 is substantially cylindrical, and one end is connect with one end of the knife handle 10, and the processing department 30 diameter is equal to the diameter of the knife handle 10.
Referring to Fig. 2, and combine Fig. 1, specifically, the side of the processing department 30 is provided at least two chip pockets 31, The chip pocket 31 is extended to one end of the knife handle 10 by the other end of the processing department 30.Two adjacent chip pockets 31 it Between be formed with land 32.The chip pocket 31 is equal with the quantity of land 32, and the chip pocket 31 and the land 32 are equal In the shape of a spiral.
In order to preferably cooperate the drilling of land 32, the chip pocket 31 is in the shape of a spiral.Each chip pocket 31 and a sword Band 32 is connected, and is connected with another land 32.Chip pocket 31 is used for when land 32 carries out drilling processing to workpiece, by drilling Clast be discharged in time, be suitable for drill for high-speed.
Chip pocket 31 is extended spirally from the other end face of the processing department 30 to one end of the knife handle 10, and it is along vertical It is gradually reduced in the cross-sectional area on each section of rotation axis A.Bore operation is being carried out using the chamfering profile cutters 100 When, 30 other end of processing department to one end of the knife handle 10 is caused in entire processing department 30 more due to adding up for stress Part close to the knife handle 10 is bigger by power.That is, processing department 30 is along the other end perpendicular to rotation axis A by processing department 30 As for one end that knife handle 10 connects, the power for needing to bear is increasing;Correspondingly, as chip pocket 31 is along perpendicular to rotary shaft The cross-sectional area in each section of line A is gradually reduced, processing department 30 in the same direction on each section cross-sectional area gradually Become larger, may make processing department 30 that there is higher intensity, to prevent breaking phenomenon.
In the present embodiment, there are four the chip pocket 31 is total to, and four chip pockets 31 and four lands 32 are equal It is surrounded on the rotation axis A, and is arranged alternately.Four chip pockets 31 and four lands 32 are both with respect to the rotation Axis A is centrosymmetric.
The other end of the processing department 30 is provided with multiple cutting blocks 33, the separate knife handle 10 on the cutting blocks 33 The edge of one end forms the first cutting edge 34, and first cutting edge 34 is extended to described by the central area of the processing department 30 The outer rim of processing department 30.First cutting edge 34 is linear, so that the chamfering profile cutters 100 are using the first cutting edge When the surface of 34 workpieces processings, can the surface of workpiece be processed smooth and smooth, avoid staying in finished workpiece surface There is protrusion.
In the present embodiment, there are four the cutting blocks 33 are total to, to enable the central area of the processing department 30 to add Work is to workpiece, and two opposite cutting blocks 33(in the other end face of the processing department 30 are that is, two non-conterminous first are cut Cut sword 34) connect in the central area of 30 other end of processing department.The length of above-mentioned two non-conterminous first cutting edge 34 Greater than the length of other two non-conterminous first cutting edge 34.Other two non-conterminous first cutting edge 34 is in the processing The central area in portion 30 is spaced a distance.
Notch 35 is formed between two adjacent cutting blocks 33, the notch 35 is connected to the chip pocket 31.It is described to lack 35 bootable clasts of mouth more swimmingly enter in chip pocket 31, and more clasts can be made to enter in chip pocket 31, Jin Ergeng The clast of drilling is discharged well.
In the shape of a spiral, 33 other end of cutting blocks connects the cutting blocks 33 with one end of the land 32.It is described to cut The lateral surface for cutting block 33 is arc surface, and the lateral surface of the land 32 is arc surface, the diameter of the lateral surface of the cutting blocks 33 Less than the lateral surface diameter of the land 32.The processing department 30 further includes inclined-plane 36, and the inclined-plane 36 is connected to the cutting Between the lateral surface of block 33 and the lateral surface of the land 32.The area that the other end face of the processing department 30 can be reduced, from And reduce feed resistance of the chamfering profile cutters 100 when carrying out drilling processing.
The lateral surface edge of the cutting blocks 33 is provided with the second cutting edge 37, and the edge on the inclined-plane 36 is provided with third The lateral surface edge of cutting edge 38, the land 32 is provided with the 4th cutting edge 39.One end of second cutting edge 37 and institute It states the first cutting edge 34 to connect, the other end of second cutting edge 37 connects with one end of the third cutting edge 38, described The other end of third cutting edge 38 connects with the 4th cutting edge 39.It is corresponding with the shape of the cutting blocks 33, described Two cutting edges 37 are in the shape of a spiral;Corresponding with the shape of the land 32, the 4th cutting edge 39 is in the shape of a spiral.The third Cutting edge 38 is linearly, and the third cutting edge 38 is crossed to form by the medial surface on the inclined-plane 36 and the land 32.
Preferably, the angle between the inclined-plane 36 and the lateral surface of the land 32 is ten degree, so that it is guaranteed that described Three cutting edges 38 have sufficient intensity, to avoid in 100 course of work of chamfering profile cutters, the third cutting edge 38 It is broken.
In the present embodiment, second cutting edge 37 and the 4th cutting edge 39 there are four, and four described second Cutting edge 37 and four the 4th cutting edges 39 are surrounded on the rotation axis A, and four second cutting edges 37 and four A 4th cutting edge 39 is centrosymmetric both with respect to the rotation axis A.
The beneficial effects of the utility model are: compared with prior art, the utility model provides a kind of chamfering profile cutter Tool 100 includes: knife handle 10 and processing department 30, wherein one end of the processing department 30 is connect with one end of the knife handle 10, described The side of processing department 30 is provided at least two chip pockets 31, forms land 32, institute between the chip pocket 31 of adjacent two State chip pocket 31 and the land 32 in the shape of a spiral, the other end of the processing department 30 is provided with multiple cutting blocks 33, adjacent Two cutting blocks 33 between form notch 35, the notch 35 is connected to the chip pocket 31, and the cutting blocks 33 are helically Shape, 33 other end of cutting blocks connect with one end of the land 32, and the lateral surface of the cutting blocks 33 is arc surface, described The lateral surface of land 32 is arc surface, and the diameter of the lateral surface of the cutting blocks 33 is less than the lateral surface diameter of the land 32. The area of the other end face of the processing department 30 can be reduced based on the above structure, to reduce the chamfering profile cutters 100 Feed resistance when carrying out drilling processing.
