Abstract

The utility model discloses a cutter provided with two arc-shaped cutting surfaces comprising a long strip-shaped cutter body. Two arc-shaped cutter surfaces (2) extend from one end of the cutter body in the direction of the length of the cutter body from two sides. Compared to the prior art, the cutter provided with two arc-shaped cutting surfaces can be used to machine two arc-shaped facets once, the facets can be more natural and beautiful, thereby the production efficiency can be increased by times, the labor time can be reduced, and the costs can be reduced.

Description

Cutter with two arc milling faces

Technical field

The utility model relates to the cutter that is used for Surface Machining, relates in particular to a kind of cutter with two arc milling faces.

Background technology

In the jewellery processing industry,, to carry out Surface Machining to materials such as gold and silver for producing the jewellery of outward appearance novel and beautiful.In the prior art,,, process repeatedly repeatedly for preparation complex surfaces decorative pattern because the shape of tool is simple.This has prolonged man-hour undoubtedly, has increased cost.

The utility model content

The utility model is the problems referred to above that will solve prior art, proposes a kind of cutter with two arc milling faces.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of cutter with two arc milling faces of design, comprises the blade of strip, is risen respectively by the blade symmetry axis in the end of said blade length direction and extends two arc knife faces to both sides.

Extend to the direction near blade on its disjunct both sides of said two arc knife faces.

The front of said blade is a plane, and perpendicular with said arc knife face.

The both sides of said blade are two planes that are parallel to each other, and these both sides and blade front are perpendicular; Outwards swell at the back side of said blade, is made up of the plane that two left-right symmetric distribute.

Compared with prior art, the utlity model has two arc milling faces, the facet that the ability time processing goes out two arcs is multiplied production efficiency, has shortened man-hour, has reduced cost.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is made detailed explanation, wherein:

Fig. 1 is the front view of the utility model preferred embodiment;

Fig. 2 is the side view of the utility model preferred embodiment;

Fig. 3 is the three-dimensional appearance of the utility model preferred embodiment;

Fig. 4 is installed in the stereoeffect in the anchor clamps for the utility model;

Fig. 5 is installed in the cutaway view in the anchor clamps for the utility model.

The specific embodiment

The utility model discloses a kind of cutter with two arc milling faces, referring to the front view shown in Fig. 1, it comprises the blade 1 of strip, extends two arc knife faces 2 to both sides in the end of said blade length direction respectively by 5 of blade symmetry axis.Extend to the direction near blade 1 on two arc knife face 2 its disjunct both sides, is to extending below in Fig. 1.The utility model adopts carbonado to process, and in the front view of Fig. 1, the orthographic projection of two arc knife faces 2 forms approximate " m " font, but jewel is carried out the facet that time processing goes out two arcs in the cut, can increase work efficiency effectively.

In conjunction with Fig. 2, the front 3 of blade 1 is a plane, and perpendicular with said arc knife face 2.When arc knife face 2 blunts, only need two arc knife faces of milling can make knife face become sharp again like this.

Referring to the stereo appearance figure of the preferred embodiment shown in Fig. 3, the both sides of said blade 1 are two planes 6 that are parallel to each other, and these both sides and blade front are perpendicular; Outwards swell at the back side of said blade 1, is made up of the plane 7 that two left-right symmetric distribute.Whole cutter also is a left-right symmetric.

Be installed in the stereoeffect and the cutaway view of 8 li of anchor clamps referring to Fig. 4, the utility model shown in 5, the back side of blade 1 protuberance just in time embeds in the groove of anchor clamps, and cutter can be limited to two side shiftings with cooperating of groove in the back side, and the location is more precisely with firm.Cutter bottom props up a step surface of anchor clamps 8, thereby the restriction cutter is in position longitudinally.Fixed screw 9 is screwed, and through pressing plate 10 cutter is fixed.

Above embodiment is merely and illustrates, non-providing constraints.Anyly do not break away from spirit of the present invention and category, and, all should be contained among the application's the claim scope its equivalent modifications of carrying out or change.

Claims
