Abstract
The invention relates to a pneumatic shear blade structure. The pneumatic shear blade structure comprises a shears head handle, a main shear blade and two auxiliary shear blades which are positioned on two sides of the main shear blade, wherein an oblique cutting plane is arranged below the front part of one of the auxiliary shear blades, and the headmost end of the auxiliary shear blade is 0.3 to 2 mm narrower than the headmost end of the auxiliary shear blade on the other side.
Description
Technical field
The invention belongs to the pneumatic tool field, be meant a kind of pneumatic shears chip architecture especially.
Background technology
In a lot of fields; Use gas to cut this pneumatic tool in the time of will cutting apart sheet metal, it is a main shear blade and two auxiliary blade of left-right symmetric shape that the gas of prior art is cut, and the bottom of described main shear blade and two auxiliary shear blades is positioned at on the plane; This shape also is the intrinsic shape of existing all scissors classes; 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; Result so is the action forward that the shearing waste material meeting overslaugh gas of this circle is cut; Make the resistance of shearing increasing, take place, can only after shearing certain distance, will this be sheared and shear operation again after waste material is removed for fear of such situation; Pause for some wide sheet materials will be done several times could be accomplished shearing work, brings many inconvenience for the shearing operation.
Summary of the invention
The objective of the invention is through a kind of new technical scheme, 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 present invention realizes through following technical scheme:
A kind of pneumatic shears chip architecture 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 the anterior below of one of them blade of said two auxiliary shear blades, said this auxiliary blade foremost than the narrow foremost 0.3-2mm of the auxiliary blade of opposite side.
As further improvement, said this auxiliary blade foremost than the narrow foremost 0.5-1.5mm of the auxiliary blade of opposite side.
As further improvement, said this auxiliary blade foremost than the narrow foremost 1.3mm of the auxiliary blade of opposite side.
The invention has the beneficial effects as follows:
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
Describe concrete technical scheme of the present invention in detail below in conjunction with accompanying drawing, specific embodiment of the present invention only is exemplary, can only be used to explain the present invention and can not be interpreted as to be limitation of the present invention.
In the present invention, described front end is when shearing operation, to contact the part that is sheared material at first; Described below just blade is sheared the direction of material contact together.
1-is shown in Figure 3 with reference to accompanying drawing, and the present invention realizes through following technical scheme.
A kind of pneumatic shears chip architecture 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 this auxiliary blade foremost than the narrow foremost 0.3-2mm of the auxiliary blade of opposite side.
As further improvement, said this auxiliary blade foremost than the narrow foremost 0.5-1.5mm of the auxiliary blade of opposite side.
As further improvement, said this auxiliary blade foremost than the narrow foremost 1.3mm of the auxiliary blade of opposite side.
In an embodiment of the present invention; 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 technical scheme of the present invention.
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 technical scheme of the present invention, and those skilled in the art can improve according to the present technique scheme certainly, and these improvement should be considered in protection scope of the present invention.
Claims (3)
1. a pneumatic shears chip architecture includes a scissors bit handle body, a main shear blade and two auxiliary shear blades that are positioned at main shear blade both sides; It is characterized in that: there is a scarf below of the front portion of said two auxiliary one of them blades of shear blade, said this auxiliary blade foremost than the narrow foremost 0.3-2mm of the auxiliary blade of opposite side.
