Abstract

The utility model provides a mold tapping knife. The mold tapping knife comprises a knife handle and a knife head, wherein a clamping groove is formed in one side of the knife handle, a fixed baffle block is fixed on the other side of the knife handle, and the knife head is connected to the other side of the knife handle; a locking unit is arranged between the clamping groove and the fixed baffle block; the knife head comprises a chamfering-cutting edge, a first cutting edge, a second cutting edge, a third cutting edge and a circular arc transition surface. The mold tapping knife has the beneficial effects that the structure is reasonable, and the use is convenient; an arc surface boss can be machined and formed once, and a chamfered face is machined without changing a cutter; a produced product is good in glossiness, high efficiency and good consistency.

Description

Cutter is attacked in a kind of moulding

Technical field

The utility model relates to hardware and cutting-tools technical field, and 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; can first with slotting cutter, global shape roughly be milled out to the processing of arc surface boss 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.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, provides 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 utility model 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.

The utility model beneficial effect 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 utility model;

Fig. 2 is the local enlarged diagram of the moulding of the present utility model 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 utility model is further described.

As shown in Figure 1 and Figure 2, a kind of moulding described in the utility model 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 preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
