Abstract
The utility model discloses a shear blade. The shear blade has a strip shape, the cutting edge of the shear blade has an inwardly recessed V-shape or arc shape, and the included angle between the V-shaped cutting edge and the bottom edge is in the range from 2.5 degrees to 3.5 degrees. The shear blade can change the stressed state of a shearing machine when shearing materials, so as to reduce power consumption, abrasion and noise of equipment.
Description
Technical field
The utility model relates to shearing equipment, is specifically related to the shear-blade on a kind of shearing equipment.
Background technology
Be used for shearing the cutter of steel bar in the prior art, because the insert design in its shearing tool is unreasonable, the indent formula V font edge of a knife, the hypotenuse and the angle between the hemline of its edge of a knife too small (generally all less than 2 degree) causes the service life of shear-blade short, because the shearing force of blade when shearing bar is bigger, therefore, the power consumption that is used to drive the driving mechanism of blade also can be bigger, because shearing force strengthens, the wearing and tearing of driver part are also more serious in the cutter in addition.For example be used to shear 850 tons of cold shears cutters of bar, in use its shear-blade almost all needs to change every day, and it is serious to be used to drive the losses in use such as driving shaft, axle sleeve and brake strip of blade in the cutter, and the noise during shearing is also bigger.Therefore, be necessary to see that to existing its blade improves.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of shear-blade is provided, and this blade can change the stress of cutter when shearing material, and the power consumption of equipment is reduced, and wearing and tearing reduce, and noise reduces.
For achieving the above object, the technical solution of the utility model is a kind of shear-blade of design, described blade is a strip, and the edge of a knife of described blade is the V font that caves inward, and the angle between the described V font edge of a knife and the hemline can be spent 30 fens between 3 degree 30 minutes 2.
Wherein, the preferred angle between the described V font edge of a knife and the hemline is 3 degree 16 minutes.
Wherein, the edge of a knife of described blade also can be designed to the arc that caves inward.
Wherein, described curved edge is at the tangent line of vertical edges position, and the angle between the hemline can be spent 30 fens between 3 degree 30 minutes 2.
Wherein, described curved edge is at the tangent line of vertical edges position, and the preferred angle between the hemline is 3 degree 16 minutes.
Advantage of the present utility model and beneficial effect are:
1, can improve the service life of blade.Because exist the defective on the insert design in former cutter, the shearing force of blade in shear history is bigger, bigger to the overall structure damage of scissors, almost all need to change blade every day.After adopting the technical scheme of pump utility model, blade can use and just change a slice after many days.
2, improved the service life of friction plate in the brake part.Because former cutter at work, it is serious to rub between the driving shaft of driving blade and excentric sleeve, the adjustment lock washer, and the spoilage of brake strip is bigger.After adopting the technical scheme of pump utility model, friction plate was changed once by original 1-2 days, became present basic can the use more than one month.
3, shorten maintenance time, improve operation rate.Because the shearing force of former cutter is bigger, need the gap of often adjusting or adjusting pad, change spare part.After adopting the technical scheme of pump utility model, the mechanical wear of cutter obviously reduces, and the adjustment number of times of adjusting pad has also reduced many, and the replacing frequency of spare part obviously reduces, and has improved effective running rate of equipment greatly.
4, improve working environment.Because former cold shears cutter machine sound super large in shear history has injury to workman's ear drum membrane unavoidably, even brings irritated mood.After adopting the technical scheme of pump utility model, in the shear history, the decibel resin of shearing sound between the machinery obviously reduces, and plays very big effect to improving working environment.
5, reduce cost.After adopting the technical scheme of pump utility model, the replacing number of times of cold shear blade, friction plate, belt has all reduced, and contributes for saving cost.
In sum, pass through as can be seen after the technological transformation, the service life of improving blade, improve friction plate service life, the maintenance time of shortening, improve operation rate, improve working environment, reduce aspect such as operating cost and all be improved.
Description of drawings
Fig. 1 is one of structural representation of the utility model shear-blade;
Fig. 2 be the utility model shear-blade structural representation two.
Among the figure: 1, blade; 2, the edge of a knife; 3, V font; 4, angle; 5, arc.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The concrete technical scheme of implementing of the utility model is:
As shown in Figure 1, a kind of shear-blade 1, described blade are strip, and the V font 3 of the edge of a knife 2 for caving inward of described blade, the angle 4 between the described V font edge of a knife 3 and the hemline can be arranged on 2 and spend 30 fens between 3 degree 30 minutes.
In the utility model, the preferred angle 4 between described V font 3 edges of a knife 2 and the hemline is 3 degree 16 minutes.
As shown in Figure 2, in the utility model, the edge of a knife 2 of described blade 1 also can be designed to the arc 5 that caves inward.Described curved edge is at the tangent line of vertical edges position, and the angle between the hemline can be spent 30 fens between 3 degree 30 minutes 2.The edge of a knife 2 of described arc 5 is at the tangent line of vertical edges position, and the preferred angle between the hemline is 3 degree 16 minutes.The structure of other structure and embodiment 1 is identical.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
