Abstract

The utility model discloses a special-shaped knife with a saw-tooth-shaped cutting face, which comprises a strip-shaped knife body (1). The saw-tooth-shaped cutting face (2) is arranged on the top of the length direction of the knife body. Compared with the prior art, the special-shaped knife with the wide saw-tooth-shaped cutting face resolves the technical problem that an existing knife cutting face is simple and only can realize forming after multiple times of processing, a plurality of saw-tooth-shaped facets can be processed after one-step knife feeding, so that production efficiency is increased exponentially, work time is shortened, and cost is reduced.

Description

Special-shaped cutter with zigzag cutting face

Technical field

The utility model relates to the cutter that is used for jewelry processing, relates in particular to a kind of special-shaped cutter with zigzag cutting face.

Background technology

In the processing of jewellery car flower,, need to carry out Surface Machining to materials such as gold and silver for producing the jewellery of outward appearance novel and beautiful.Conventional cutter has only some common shape, so can only do the highway tread pattern type under some routines, will process repeatedly repeatedly like the complicated decorative pattern of need preparation, takes time and effort very much, but also does not reach desirable effect.

The utility model content

The utility model is the problems referred to above that will solve prior art, proposes a kind of special-shaped cutter with zigzag cutting face.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of special-shaped cutter with zigzag cutting face of design, comprises the blade of strip, and the top of said blade length direction has zigzag cutting knife face.

Above-mentioned bite bread contains cross section be leg-of-mutton side along link to each other successively second, third, the 4th, the 5th groove, wherein second, third groove and the 4th, the 5th groove are distributed in the vertical plane of symmetry of blade both sides symmetrically.

Being provided with cross section between above-mentioned second groove and the blade side is first groove of circular arc, is provided with the 6th groove that cross section is a circular arc between the other side of said the 5th groove and blade.

The front of above-mentioned blade is a plane, and perpendicular with said the first, second, third, fourth, the 5th, the 6th groove.

The both sides of above-mentioned blade are two planes that are parallel to each other, and these both sides and blade front are perpendicular; The said blade back side is provided with the projection of the strip of protuberance, and the cross section of this projection is a triangle.

Compared with prior art, the utlity model has the zigzag cutting face of wide cut, solved that the Tool in Cutting face was simple in the past; Need the technical problem that repeatedly processing can moulding, once descend cutter can process a plurality of zigzag facets, production efficiency is multiplied; Shorten man-hour, 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 special-shaped cutter with zigzag cutting face, it comprises the blade 1 of strip, and the top of blade length direction has zigzag cutting knife face 2.

Front view referring to the preferred embodiment shown in Fig. 1; Said bite bread contains cross section be leg-of-mutton side along link to each other successively second, third, the 4th, the 5th groove (2b, 2c, 2d, 2e), wherein second, third groove and the 4th, the 5th groove are distributed in blade 1 vertical plane of symmetry 5 both sides symmetrically.Being provided with cross section between said second groove and blade 1 side is the first groove 2a of circular arc, is provided with the 6th groove 2f that cross section is a circular arc between said the 5th groove and the blade 1 other side.The front 3 of said blade 1 is a plane, and perpendicular with said the first, second, third, fourth, the 5th, the 6th groove (2a, 2b, 2c, 2d, 2e, 2f).Among Fig. 1, each groove side edge connects successively, as the sawtooth that rises and falls.The utility model adopts carbonado to process, and jewel is being carried out in the cut, but time processing goes out 6 facets, has greatly improved operating efficiency.

In conjunction with Fig. 2,3, two planes of both sides 6 for being parallel to each other of blade 1 in the preferred embodiment, these both sides 6 are perpendicular with the blade front; The said blade back side is provided with the projection 7 of the strip of protuberance, and the cross section of this projection is a triangle.

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 projection 7 of blade 1 protuberance just in time embeds in the groove of anchor clamps, and projection 7 can limit cutter to two side shiftings with cooperating of groove, 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.
