Abstract

The utility model discloses a toothed cutter. Jagged grain is arranged on one side face of the cutter, extending to the edge of the cutter. A bevel is arranged on the other side face of the cutter and extends to the edge of the cutter. The bevel intersects with the jagged grain to form a jagged edge. The jagged edge of the toothed cutter is formed by the jagged grain on one side face and the bevel on the other side face, which are intersected with one another. When the edge of the cutter turns blunt, the user only needs to polish the bevel, and the polished bevel can still be intersected with the jagged grain to form a sharp jagged edge. Therefore, the toothed cutter is convenient to polish and the service life of the toothed cutter is greatly improved as compared with conventional toothed cutters.

Description

The tooth punching cutter

Technical field

The utility model relates to a kind of cutter.

Background technology

The tooth punching cutter is used widely in daily life because therefore its blade position indentation has higher sharpness.For example, the tooth punching cutter is widely used in cutting meat etc.

Cutter is after use after a while, and its blade is understood rust, and the serrated edge of tooth punching cutter is no exception.For anodontia blade, on knife-grinding appliance, can make blade sharp again along polishing blade position, one or both sides., for the blade of tooth punching, polish with said method and but can damage serrated edge, and also do not have other preferable polishing process.This makes that just the service life of tooth punching cutter is shorter, in case the serrated edge rust has just lost use value, has caused waste in a way.

The utility model content

Technical problem to be solved in the utility model provides a kind of tooth punching cutter, and this tooth punching cutter can be polished easily, makes its serrated edge keep sharp, greatly increases the service life.

For solving the problems of the technologies described above, has the zigzag texture on the side of the utility model tooth punching cutter, described zigzag texture extends to the blade place, has the inclined-plane on another side of described cutter, described inclined-plane extends to the blade place, and described inclined-plane and described zigzag texture intersect the formation serrated edge.

Described zigzag texture is made up of a plurality of v-depressions, forms an inverted V-shaped cell wall between per two adjacent v-depressions.

The angle that described v-depression and inverted V-shaped cell wall and described blade intersect is between 60 degree are spent to 120.

It is acute angle that described inclined-plane and described zigzag texture intersect.

The serrated edge of the utility model tooth punching cutter is to be intersected and formed by the inclined-plane on the zigzag texture on the side and another side, when edges dull, only need polish to this inclined-plane, the inclined-plane after the polishing still intersects formation sharp sawteeth shape blade with the zigzag texture.Therefore the polishing of the utility model tooth punching cutter is convenient, and service life, more traditional tooth punching cutter prolonged greatly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the schematic diagram of a side of the utility model tooth punching cutter;

Fig. 2 is the partial enlarged drawing of frame of broken lines A inside among Fig. 1;

Fig. 3 is the schematic diagram of another side of the utility model tooth punching cutter;

Fig. 4 is the partial enlarged drawing of frame of broken lines B inside among Fig. 3.

Reference numeral is among the figure: 1-blade; 2a, 2b-knife face; 21-v-depression; 22-inverted V-shaped cell wall; 3-knife back; 31-inclined-plane; A, B-frame of broken lines.

The specific embodiment

See also Fig. 1 and Fig. 2, have the zigzag texture on the side 2a of the utility model tooth punching cutter.Described zigzag texture is made up of a plurality of v-depressions 21, forms an inverted V-shaped cell wall 22 between per two adjacent v-depressions 21.Described zigzag texture extends to blade 1 place from the knife back 3 of this side 2a always.The angle that the v-depression 21 of described zigzag texture and inverted V-shaped cell wall 22 and blade 1 intersects at 60 degree between 120 degree, desirable 70 degree of preferred value, 75 degree, 80 degree, 90 degree, 100 degree, 110 degree, 115 degree, 120 degree etc.

See also Fig. 3 and Fig. 4, have inclined-plane 31 on another side 2b of described cutter, described inclined-plane 31 extends to blade 1 place from the middle front part (for example, this side 2b is apart from 1/20 place of blade 1) of this side always.It is acute angle that described inclined-plane 31 intersects with described zigzag texture, and the intersection area forms serrated edge 1.

In the above-described embodiments, the zigzag texture extends to blade 1 place in the knife back 3 places of 2a from the side always.During enforcement, the zigzag texture also can extend to blade 1 place apart from 2/3 or 1/2 place or 1/3 place of blade from this side 2a.

In the above-described embodiments, have on the side 2b on inclined-plane 31 and do not have the zigzag texture.During enforcement, the part of removing inclined-plane 31 on the 2b of this side also can have the zigzag texture.The zigzag texture can spread all over the part of removing inclined-plane 31 on the 2b of this side, also can partly be distributed in the part of removing inclined-plane 31 on the 2b of this side.

The utility model tooth punching cutter intersects by zigzag texture on the side and the inclined-plane on another side, forms serrated edge.Its biggest advantage is that polishing is convenient, when edges dull, only needs the polishing inclined-plane can form sharp blade again.During polishing, in fact original serrated edge has been produced damage really, the inclined-plane after the polishing and zigzag texture are crossing has been deformed into new sharp knife edges.This has just prolonged the service life of tooth punching cutter greatly.

In addition, the utility model tooth punching cutter has the zigzag texture in a side at least, and the zigzag texture not only can intersect the formation serrated edge with the inclined-plane, can also form a plurality of air ducts by V-shaped groove.Like this, the utility model just has air permeability and good at the cutting article when (for example food), makes the article after the cutting can not be attached to tool surface, but leaves cutter arrangement on one's own initiative aside.
