Abstract
The utility model relates to an improved structure of an air shear blade. The improved structure comprises a shear head handle body, a main shear blade and two auxiliary shear blades arranged on two sides of the main shear blade. A diagonal plane is arranged below the front portion of one blade of the two auxiliary shear blades, and the front end of one auxiliary shear blade is 0.3-2 mm narrower than that of the other auxiliary shear blade on the other side.
Description
Technical field
The utility model belongs to the pneumatic tool field, is meant a kind of improvement structure of pneumatic shears sheet especially.
Background technology
In a lot of fields, can use gas to cut this pneumatic tool in the time of cutting apart sheet metal, it is that a main shear blade and two auxiliary blade of left-right symmetric shape are formed cutting out section that the gas of prior art is cut; The bottom of described main shear blade and two auxiliary shear blades is positioned at on the plane; Two auxiliary blade are the left-right symmetric structure, and this shape also is the intrinsic shape of all scissors classes, are using such gas to cut when shearing sheet metal; Can occur one and shear waste material; This shears waste material can constantly increase along with the continuation of shear action with the form of similar circle, and result so is the action forward that the shearing waste material meeting overslaugh gas of this circle is cut, and makes the resistance of shearing increasing; Take place for fear of such situation; Can only after shearing certain distance, to this be sheared and shear operation again after waste material is removed, could accomplish shearing work, bring many inconvenience for the shearing operation for the pause that some wide sheet materials will be done several times.
The utility model content
The purpose of the utility model is through a kind of new technical scheme, and this technical scheme can overcome when shearing operation the continuity that influences operation because of the existence of shearing waste material, reduces and shears the resistance that waste material is cut gas, improves shear efficiency.
The utility model is realized through following technical scheme:
The improvement structure of pneumatic shears sheet includes a scissors bit handle body, a main shear blade and two auxiliary shear blades that are positioned at main shear blade both sides; There is a scarf below of the front portion of said two auxiliary one of them blades of shear blade, said should auxiliary shear blade foremost than the narrow foremost 0.3-2mm of the auxiliary shear blade of opposite side.
As further improvement, said should auxiliary shear blade foremost than the narrow foremost 0.5-1.5mm of the auxiliary shear blade of opposite side.
As further improvement, said should auxiliary shear blade foremost than the narrow foremost 1.3mm of the auxiliary shear blade of opposite side.
The beneficial effect of the utility model is:
The improvement of gas being cut through the present technique scheme; Use the gas of present technique scheme to cut when shearing operation, the bar shaped waste material that is produced is no longer crooked by the circle mode, but bent to a lateral bending with the expansion spiral way; No longer hinder advancing that gas cuts, also can guarantee the continuity when gas is cut work.

The specific embodiment
Below in conjunction with the concrete technical scheme of accompanying drawing detailed description the utility model, the specific embodiment of the utility model only is exemplary, can only be used to explain the utility model and can not be interpreted as to be the restriction to the utility model.
1-is shown in Figure 3 with reference to accompanying drawing, and the utility model is realized through following technical scheme.
The improvement structure of pneumatic shears sheet includes a scissors bit handle body 39, one main shear blades 43 and two the auxiliary shear blades (42,45) that are positioned at main shear blade both sides; There is a scarf 46 below of the front portion of said two one of them blades 45 of auxiliary shear blade, said should auxiliary shear blade foremost than the narrow foremost 0.3-2mm of the auxiliary shear blade of opposite side.
As further improvement, said should auxiliary shear blade foremost than the narrow foremost 0.5-1.5mm of the auxiliary shear blade of opposite side.
As further improvement, said should auxiliary shear blade foremost than the narrow foremost 1.3mm of the auxiliary shear blade of opposite side.
In the embodiment of the utility model; Scissors bit handle body and main shear blade structure do not change; Only be through one of them improves to two auxiliary shear blades; Another maintenance is constant with prior art, as for which side of selecting main shear blade need not stress, all can realize the purpose of the technical scheme of the utility model.
When selecting auxiliary shear blade to a side to improve; Should assist the root direction of shear blade to adopt modes such as cutting or polishing to handle from the lower direction of head the former auxiliary shear blade of this side; The mode of this processing is from processing such as anterior cutting that forms an angle to root direction same level face or polishings, also can directly adopt different dies to process during fabrication and all can; The auxiliary shear blade of after treatment this is compared with the auxiliary shear blade of opposite side; The anterior narrow 0.3-2mm of auxiliary shear blade than opposite side; Be preferably than the anterior narrow 0.5-1.5mm of the narrow auxiliary shear blade of opposite side, most preferably be than the anterior narrow 1.3mm of the narrow auxiliary shear blade of opposite side.
After being installed to main shear blade and two auxiliary shear blades on the scissors bit handle; The anterior bottom of the auxiliary shear blade of the same side, bottom that main shear blade is anterior at grade; The plane 0.3-2mm at the place, anterior bottom of the auxiliary shear blade of the same side, bottom that the forefront vertical range master shear blade of the anterior bottom of the auxiliary shear blade of opposite side after treatment is anterior; 0.5-1.5mm preferably, optimum is 1.3mm.Like this because the auxiliary shear blade of main shear blade both sides no longer is the left-right symmetric shape; When carrying out cutting operation, occurred two auxiliary shear blades with time of contact of material to be cut not simultaneously; Produce the variation of power, therefore sheared waste material is expansion under the effect of out-of-balance force spirality.
The above only is the specific descriptions to the utility model technical scheme, and those skilled in the art can improve according to the present technique scheme certainly, and these improvement should be considered in the protection domain of the utility model.
