Abstract

The invention provides a novel cutter of a cutting bed, belongs to the technical field of cutters, and solves such problems as low work efficiency, no guarantee of cutting precision and easy picking-up of cut materials by knife edges in existing structures. The novel cutter of the cutting bed is characterized by comprising a cutter main body, wherein the cutter main body takes the shape of folded plates folded at a certain angle; the knife edges are arranged at the lower side of the cutter main body; and fixing holes are formed in the cutter main body above the knife edges. In the novel cutter of the cutting bed, the structure of the cutter main body taking the shape of folded plates folded at a certain angle is as follows: the cross section of the cutter main body is V-shaped, and consists of a left side plate and a right side plate; and an included angle A formed by the left side plate and the right side plate is 50-70 degrees. The novel cutter of the cutting bed has such advantages as high cutting precision, high cutting efficiency, long service life, low production cost and good use quality.

Description

The novel cut-off knife of cutting

Technical field

The invention belongs to cut-off knife technical field, refer 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, when cutting " V " the shape edge of a knife, need cutting to complete for twice, inefficiency and cutting precision can not guarantee, 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 novel cut-off knife that the object of this invention is to provide a kind of cutting, 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 object of the present invention is achieved like this:

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.

Another kind of structure as cut-off knife body, to its shape, exist slightly different 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 towards the inclination of 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 present invention compared to existing technology outstanding and useful technique effect is:

1, the present invention adopts that to be provided with the blade of pre-determined tilt angle reasonable with cut material binding site and angle, avoids in cutting work cut-off knife to cut material and takes up, and has improved the degree of accuracy and the precision of product.

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

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

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is structure top view of the present invention.

Fig. 3 is texture edge view of the present invention.

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

The specific embodiment

Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, 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 fixing structures such as cylinder by hole 3 and cutting that arrange on cut-off knife body 1 are fixed, cut-off knife body arranges with cropped thing is vertical, by cylinder, drive cut-off knife body to pump, 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 accompanying drawing file of the present invention, 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 towards the inclination of 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 invention, not limits the scope of the invention according to this, therefore: all equivalences of doing according to structure of the present invention, shape, principle change, within all should being covered by protection scope of the present invention.
