Abstract
The invention discloses a molding tapping knife, comprising a knife handle and a tool bit, wherein the knife handle is in a cylindrical structure; a clamping groove is formed in one side of the knife handle; a fixed baffle block is arranged at the other side of the knife handle; the tool bit is connected to the other side of the knife handle; a lock nut is arranged between the clamping groove and the fixed baffle block; the tool bit comprises a chamfer cutting edge, a first cutting edge, a second cutting edge, a third cutting edge and an arc transition surface. The molding tapping knife is reasonable in structure, and convenient to use and can be used for machining and mold an arc lug boss one time and machining the chamfer surface, a tool does not need to be replaced, and the produced product is good in smoothness, fast in efficiency and good in consistence.
Description
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly cutter is attacked in a kind of moulding.
Background technology
In machining, often can encounter high-grade handware is carried out to the processing of arc surface boss; to the processing of arc surface boss, can first with slotting cutter, global shape roughly be milled out at present; use again rose cutter fine finishining curved surface; because the arc surface on center line both sides is fixed a cutting tool, the position of participation cutting is different, so just causes the circular arc on symmetrical center line both sides inconsistent.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of rational in infrastructure, easy to use, can attack cutter to a kind of moulding of arc surface boss time processing moulding.
For achieving the above object, the present invention is by the following technical solutions: cutter is attacked in a kind of moulding, comprise handle of a knife and cutter head, described handle of a knife is cylindrical structural, handle of a knife one side is provided with clamping groove, and opposite side arranges fixed stop, and cutter head is connected in this handle of a knife opposite side, between described clamping groove and fixed stop, be provided with locking nut, described cutter head comprises chamfering cutting edge, the first cutting edge, the second cutting edge, the 3rd cutting edge and arc-shaped transitional surface.
Further, between described chamfering cutting edge and the first cutting edge, be 20 ° of angle settings.
Further, between described the first cutting edge and the second cutting edge, be 90 ° of angle settings.
Further, between described the second cutting edge and the 3rd cutting edge, be 135 ° of angle settings.
Further, symmetrical structure centered by described cutter head.
Beneficial effect of the present invention is: it is reasonable that knife structure is attacked in this moulding, easy to use, can be to the moulding of arc surface boss time processing, and chamfering face, not needing to change cutter, the product glossiness of making is good, and efficiency is fast, high conformity.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram that cutter is attacked in moulding of the present invention;
Fig. 2 is the local enlarged diagram of the moulding of the present invention cutter head of attacking cutter.
In figure: 1-handle of a knife, 2-clamping groove, 3-locking nut, 4-fixed stop, 5-cutter head, 6-arc-shaped transitional surface, 7-chamfering cutting edge, 8-the first cutting edge, 9-the second cutting edge, 10-the 3rd cutting edge.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1 and Figure 2, a kind of moulding of the present invention is attacked cutter and is comprised handle of a knife 1 and cutter head 5, described handle of a knife 1 is cylindrical structural, handle of a knife 1 one sides are provided with clamping groove 2, opposite side arranges fixed stop 4, and cutter head 5 is connected in this handle of a knife 1 opposite side, between described clamping groove 2 and fixed stop 4, is provided with locking nut 3.In machining process, handle of a knife 1 clamping, among chuck, occurs that cutter is loosening when avoiding workpiece, and the chuck screwing with locking nut carries out secondary to be fixed.
Described cutter head 5 comprises chamfering cutting edge 7, the first cutting edge 8, the second cutting edge 9, the 3rd cutting edge 10 and arc-shaped transitional surface 6, and arc-shaped transitional surface 6 has effectively increased the intensity of cutter.Between described chamfering cutting edge 7 and the first cutting edge 8, being 20 ° of angle settings, is 90 ° of angle settings between described the first cutting edge 10 and the second cutting edge 9, between described the second cutting edge 9 and the 3rd cutting edge 10, is 135 ° of angle settings.In to arc surface boss process, can time processing moulding, the good product consistency of making, highly polished, boss root is carried out to chamfered.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
