Abstract

The utility model provides a novel cutter of a cutting bed, and belongs to the technical field of cutters, wherein the novel cutter solves the problems that due to an existing structure, work efficiency is low, cutting precision can not be ensured, and a blade easily takes up cut material. The novel cutter is characterized by comprising a cutter body, the cutter body is folded up by a certain degree to form a folded plate shape, the lower side of the cutter body is provided with a blade, and a fixing hole is formed in the position, above the blade, of the cutter body. After the cutter body is folded up by the certain degree to form the folded plate shape, structurally, the cross section of the cutter body is in a V shape, the cutter body comprises a left side plate and a right side plate, and the included angle A of the left side plate and the right side plate ranges from 50 degrees and 70 degrees. The novel cutter has the advantages of being high in cutting precision, high in cutting efficiency, long in service life, low in production cost, excellent in use quality and the like.

Description

The novel cut-off knife of cutting

Technical field

The utility model belongs to cut-off knife technical field, refers in particular to a kind of novel cut-off knife of cutting.

Background technology

At present, single for the planform of automatic cutting bed cut-off knife in market, in the time of cutting " V " the shape edge of a knife, need cutting to complete for twice, inefficiency and cutting precision can not ensure, secondly the design of the blade of existing cut-off knife exists the phenomenon easily taking up cutting material in cutting work, is unfavorable for the steady operation of cutting

Summary of the invention

The purpose of this utility model is to provide a kind of novel cut-off knife of cutting, and it has solved the problems such as in prior art, the cutting precision of cut-off knife is inadequate, cutting efficiency is low, service life is short, production cost is high, and has promoted the service property (quality) of cut-off knife.

The purpose of this utility model is achieved in that

The novel cut-off knife of cutting, is characterized in that: comprise cut-off knife body, described cut-off knife body is the flap-like after doubling certain angle, and the downside of cut-off knife body is provided with blade, and the cut-off knife body of blade top is provided with fixedly uses hole.

In the novel cut-off knife of above-mentioned cutting, the structure that described cut-off knife body is the flap-like after doubling certain angle is: the cross section of cut-off knife body is V-shaped, comprises left plate and right plate, and the included angle A that left plate and right plate form is 50～70 degree.

In the novel cut-off knife of above-mentioned cutting, described left plate and the included angle A of right plate are 60 degree.

As the another kind of structure of cut-off knife body, exist slightly different to its shape from said structure: the structure that described cut-off knife body is the flap-like after doubling certain angle is: comprise left plate, right plate and be positioned at arc connecting plate between the two, the radian of arc connecting plate is 50～70 degree.

In the novel cut-off knife of above-mentioned cutting, the structure of described blade is: the downside of this external surface of cut-off knife is provided with the blade face tilting towards cut-off knife body internal surface, and the included angle B of blade face and cut-off knife body internal surface is 5～10 degree.

In the novel cut-off knife of above-mentioned cutting, described blade face and the included angle B of cut-off knife body internal surface are 9 degree.

In the novel cut-off knife of above-mentioned cutting, described cut-off knife body adopts HSS high-speed steel to make.

The utility model compared to existing technology outstanding and useful technique effect is:

1, it is reasonable with cut material binding site and angle that the utility model adopts the blade that is provided with pre-determined tilt angle, avoids in cutting work cut-off knife to cut material and take up, and improved the degree of accuracy and the precision of product.

2, the edge of a knife that in the utility model, cut-off knife one action is determined is V-shaped, has promoted working (machining) efficiency.

3, cut-off knife of the present utility model adopts HSS high-speed steel to make, have advantages of high temperature resistant, not frangibility, be suitable for high-speed working condition.

Brief description of the drawings

Fig. 2 is structure top view of the present utility model.

Fig. 3 is texture edge view of the present utility model.

Fig. 4 is B-B sectional view in Fig. 2.

Detailed description of the invention

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4:

The novel cut-off knife of cutting, comprises cut-off knife body 1, and described cut-off knife body is the flap-like after doubling certain angle, and the downside of cut-off knife body is provided with blade 2, and the cut-off knife body of blade top is provided with fixing with hole 3.

The concrete using method of this cut-off knife is: the structures such as the fixing cylinder by hole 3 and cutting arranging on cut-off knife body 1 are fixed, cut-off knife body is vertical with cropped thing to be arranged, drive cut-off knife body to pump by cylinder, a cutting of cut-off knife just forms the edge of a knife of " V " shape, therefore avoid repeatedly cutting, promoted two operating efficiencies.

The structure that described cut-off knife body is the flap-like after doubling certain angle is: the cross section of cut-off knife body is V-shaped, comprises left plate 4 and right plate 5, and the included angle A that left plate and right plate form is 50～70 degree.

Described left plate and the included angle A of right plate are 60 degree.

In the utility model accompanying drawing file, are all schematic diagrames of this kind of structure: the structure that described cut-off knife body is the flap-like after doubling certain angle is: comprise left plate, right plate and be positioned at arc connecting plate 6 between the two, the radian of arc connecting plate is 50～70 degree.

The radian of above-mentioned included angle A and arc connecting plate all can be adjusted according to actual service condition.

The structure of described blade is: the downside of this external surface of cut-off knife 7 is provided with the blade face 8 tilting towards cut-off knife body internal surface, and the included angle B of blade face and cut-off knife body internal surface is 5～10 degree.

Described blade face and the included angle B of cut-off knife body internal surface 9 are 9 degree.In actual use, the angle of above-mentioned included angle B is excessive, easily causes the precision of cutting not high, easily takes up cloth simultaneously; Included angle B angle too small, blade easily damages.

Described cut-off knife body adopts HSS high-speed steel to make.

Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
