Abstract
The invention relates to the field of cutters, in particular to a chamfering cutter used for chamfering processing for plastic components (PC). The chamfering cutter comprises a cutter bar and a cutter bit, wherein the cutter bar and the cutter bit are made from hard alloy materials. A first cutting edge, a second cutting edge, and a third cutting edge are arranged on the cutter bit. A transitional surface with shrunken diameter is arranged between the cutter bar and the cutter bit, wherein the transitional surface and the axial direction of the cutter bar form a cone angle of 36 degrees. The first cutting edge is connected with the lower end of the transitional surface, and is parallel to the axial direction of the cutter bar. The second cutting edge is connected with the lower end of the first cutting edge, and an included angle of 5 degrees is formed between the second cutting edge and the axial direction of the cutter bar. The third cutting edge is arranged at the lower end surface of the cutter bit, wherein the cutter bar and the cutter bit are both processed by quenching. The chamfering cutter has the advantages of improving working efficiency, and due to coherent processing, the degree of finish of a processed surface is good, and the surface quality of a processed piece is improved.
Description
Technical field
The present invention relates to the cutter field, particularly a kind of chamfering tool for the PC plastic parts being carried out chamfer machining.
Background technology
When the PC plastic parts is carried out chamfering, normally carry out chamfering with common drill bit or lathe tool, add man-hour for the fluted workpiece of some tools, need to process first a groove, and then do chamfering, can't once finish processing and the chamfering of groove, working (machining) efficiency is low, and because be to process in two steps, so the fineness of finished surface often can't reach requirement, machined surface quality is relatively poor.
Summary of the invention
When the object of the invention is to for the existing chamfer tool processing PC plastic parts described in the background technology, processed surface smoothness can't reach requirement, and the poor problem that gets of machined surface quality provides a kind of chamfering tool that can solve foregoing problems.
The technical scheme that can realize goal of the invention of the present invention is as follows:
A kind of chamfering tool, the knife bar and the cutter head that comprise Hardmetal materials, be provided with the first cutting edge, the second cutting edge and the 3rd cutting edge on the cutter head, be provided with and the excessive face of cutter spindle to the reduced that becomes 36 ° of cone angles between knife bar and the cutter head, the first cutting edge is connected with the lower end of excessive face, the first cutting edge and knife bar axially parallel, the second cutting edge is connected with the lower end of the first cutting edge, the second cutting edge and cutter spindle to angle be 5 °, the 3rd cutting edge is arranged on the lower surface of cutter head, wherein, knife bar and cutter head are all processed by high-frequency quenching.
The vertical height of described the second cutting edge is 1.5mm.
The length of described the 3rd cutting edge is 1.6mm.
Beneficial effect of the present invention has improved operating efficiency for can disposablely finishing the operation of fluting and chamfering, because processing continuity so processed surface smoothness are good, has improved the surface quality of workpiece.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
The specific embodiment
As shown in Figure 1, a kind of chamfering tool, comprise knife bar 1 and cutter head 2, be provided with the first cutting edge, the second cutting edge 4 and the 3rd cutting edge 5 on the described cutter head 2, be provided with the excessive face 6 that axially becomes the reduced of 36 ° of cone angle a with knife bar 1 between knife bar 1 and the cutter head 2, the first cutting edge is connected with the lower end of excessive face 6, the first cutting edge and knife bar 1 axially parallel, the second cutting edge 4 is connected with the lower end of the first cutting edge, the second cutting edge 4 and knife bar 1 axial angle b is 5 °, and the 3rd cutting edge 5 is arranged on the lower surface of cutter head 2; The vertical height of described the second cutting edge 4 is 1.5mm; The length of described the 3rd cutting edge 5 is 1.6mm, and wherein, knife bar and cutter head all adopt the Hardmetal materials of high-frequency quenching, can improve like this rigidity of cutter, increases the service life.
