Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
Scissor blade 1 as shown in Figure 1, including be connected with each other cutter head portion 2 and connecting portion 3, the cutter head portion 2 include phase
The blade 5 and the knife back 6 for connecting, the blade 5 are divided into the both sides in cutter head portion 2 with the knife back 6, and blade 5 includes interior blade surface 7, sword
Mouth 4 and outer blade surface 8, the interior blade surface 7 is opposite with outer blade surface 8 and is connected the knife back 6 and cutting edge 4 respectively, and the connecting portion 3 is provided with
Hinge hole 10, it is characterised in that the outer blade surface 8 is the cancave cambered surface that interior blade surface 7 is moved closer to from the lateral direction of cutting edge 4 of the knife back 6.
The outer blade surface of traditional scissor blade is plane or arch cambered surface, the angle of outer blade surface and interior blade surface all than larger,
In the case where the consistency of thickness of the knife back 6, outer blade surface width are equal, outer blade surface 8 is arranged to cancave cambered surface, necessarily causes interior blade surface 7
Smaller angle can be formed with outer blade surface 8 so that blade is more sharp.
The minimum angle that the outer blade surface 8 is formed with interior blade surface 7 is 20 °~28 °, and the thickness of the cutting edge 4 is the knife back 6
The 1%~5% of thickness, angle is too small, blade 5 can be caused excessively soft or excessively crisp, lowers service life, and the excessive then blade of angle becomes
It is blunt.
The minimum angle that the outer blade surface 8 is formed with interior blade surface 7 is 8 °~15 °, and the thickness of cutting edge 4 is the thickness of the knife back 6
20%~40%, be provided with the blade 5 it is a plurality of along the bearing of trend of blade 5 equidistantly arrangement strip groove 11, bar shaped
Groove 11 forms openend 12 in interior blade surface 7 and the joining place of outer blade surface 8, and extends to form blind end 13 to the direction of the knife back 6.
The reality of scissor blade 1 for being provided with strip groove 11 is tooth shear blade, due to being provided with strip groove 11 so that cut
The remitted its fury of knife blade 1, in order to improve its physical life, prevents fracture, therefore, the thickness of its cutting edge 4 and the thickness of the knife back 6
Than as far as possible larger, but also to keep it sharp enough, therefore by substantial amounts of experiment and theoretical calculation, find to work as outer blade surface
8 is 8 °~15 ° with the minimum angle that interior blade surface 7 is formed, when the thickness of cutting edge 4 is the 20%~40% of the thickness of the knife back 6, scissors
The physical property and sharpness of blade 1 are in a relatively optimal state.
The strip groove 11 is in the arc-shaped, and center of arc's deflection connecting portion 3 side, the shape is cut when meeting scissor cut
The track that knife blade 1 is rotated around hinge hole 10.
The line of the center of arc of each strip groove 11 is a straight line, and the bearing of trend of the blade 5 is cutter head portion 2
Length direction, the bearing of trend of the strip groove 11 is the width in cutter head portion 2, and the strip groove 11 is from openend
The distance of 12 to blind end 13 accounts for cutter head portion 2 positioned at the 58%~73% of the width of the position of strip groove 11, it is ensured that cut
The intensity of knife blade 1, while being also to make when tooth is cut to enable to blind end 13 with another scissors knife using the scissor blade 1
Retention gap does basis between the cutting edge 4 of piece 1.
A kind of straight snips as shown in Figure 4, the cross-articulation of scissor blade 1 for being not provided with strip groove 11 by two panels is formed, and two
The a positive and a negative of scissor blade 1 cooperates, and two hinge holes 10 are relative and are hinged by hinge 14, the phase of interior blade surface 7 in two cutter head portions 2
Patch, two connecting portions 3 are connected to handle 15 away from the one end in cutter head portion 2, when two handles 15 are separated from each other, the phase of two blade 5
Right, when two handles 15 are mutually drawn close, two blades 5 are also mutually drawn close to partly or entirely overlap.
The outer blade surface 8 of two scissor blades 1 is cancave cambered surface, necessarily enables that interior blade surface 7 forms smaller folder with outer blade surface 8
Angle so that blade is more sharp, it is also just more sharp with the straight snips that this is made.
A kind of tooth is cut, and is cut by a piece of scissor blade 1 for being not provided with strip groove 11 and a piece of strip groove 11 that is provided with
The cross-articulation of knife blade 1 is formed, and described a positive and a negative of two scissor blade 1 cooperates, and two hinge holes 10 are relatively and by hinge
14 are hinged, and the interior blade surface 7 in two cutter head portions 2 is affixed, and two connecting portions 3 are connected to handle 15 away from the one end in cutter head portion 2, when two
When handle 15 is separated from each other, two blades 5 are relative, and when two handles 15 are mutually drawn close, two blades 5 are also mutually drawn close to part or complete
Portion overlaps.
The outer blade surface 8 of two scissor blades 1 is cancave cambered surface, necessarily enables that interior blade surface 7 forms smaller folder with outer blade surface 8
Angle so that blade is more sharp, it is also just more sharp with the straight snips that this is made.
In two scissor blade 1, the width of cutter head portion 2 without strip groove 11 is less than the cutter head portion 2 for having strip groove 11
Width, two handle 15 is mutually drawn close when offseting, and two blades 5 are partly or entirely overlapped, the knife without strip groove 11
Gap is left between the blind end 13 of sword 5 and strip groove 11, to realize the incomplete shearing function that tooth is cut.
