Abstract
The utility model provides a soft timber rotary -cut cutter, belongs to the wood working machinery field. This soft timber rotary -cut cutter includes the cutting edge and the cutter body of rectangular shape, and the cutter body of rectangular shape includes back of a knife blade face, sword side and cutter body face slightly, and sword side and the cutter body contained angle between slightly is the cutting edge basil of 17.5 -18.5 degree, the cutting edge of rectangular shape includes cutting edge surface, cutting edge face and cutting edge top surface slightly, and the cutting edge contained angle between face and the cutting edge surface slightly be 1 degree the little basil in sword top, and cutting edge top surface and the cutter body contained angle between the face slightly are 1 degree sword and push up a little basil slightly. This rotary -cut cutter has improved the abrasion resistance ability of rotary -cut sword cutting edge mouth, has improved the sharpness and the anti -impact of cutting edge blade, and the thick outer surface of wood mask of treating processing simultaneously has the effect of the press polish of smoothing, has improved the smooth finish of timber veneer and the product quality grade of veneer.
Description
Technical field
The utility model relates to a kind of softwood rotary cutter, belongs to woodworking machinery field.
Background technology
Round log peeler is very welcome equipment in wood processing machinery, rotary-cut efficiency is very high, but the peeling knife shear-steel material that existing round log peeler adopts adopts 6CrW2Si alloy tool steel to do blade shear-steel mostly, blade shear-steel hardness HRC59-60, shear-steel angle 21-23 °.The peeling knife of this material and angle can only rotary-cut medium hardness, the timber of intermediate density.Density is 0.5-0.8 gram/cc, as Chinese Manchurian ash, and nanmu, Indonesia's lauan, teaks etc., and rotary-cut softwood, low-density timber, when density is below 0.4 gram/cc, as Chinese poplar, linden, the blbizzia falcata wood etc. of Indonesia, just inadaptable, rotary-cut about three section just needs to whet a knife, tool changing.Otherwise have a strong impact on efficiency and the quality of rotary-cut.
Summary of the invention
For solving the problem, the utility model provides a kind of softwood rotary cutter, by brazing edge steel to improve edge hardness and wearability, reduces blade drift angle degree, to improve sharpness and the wearability on cutter top; Blade face and cutter hub slightly face open little sword, to improve operating efficiency and the quality of cutter.
The technical solution of the utility model is: a kind of softwood rotary cutter, comprise blade and the cutter hub of strip, the cutter hub of described strip comprises knife back face, cutter side and cutter hub slightly face, and cutter side and the cutter hub angle slightly between face is blade basil c, and blade basil c is 17.5-18.5 degree; The blade of described strip comprises blade face, blade slightly face and blade end face, the angle of blade slightly between face and blade face is the little basil a in cutter top, the little basil a in cutter top is 1 degree, and blade end face and the cutter hub angle slightly between face is the cutter top slightly little basil b in face, and the cutter top slightly little basil b in face is 1 degree.
Brazing is adopted to inlay the integrative-structure of steel between the blade of described strip and the cutter hub of strip.
The cutter hub of described strip is provided with the cutter hub screw of 54 uniform M16, and described knife back face is provided with the knife back screw of 10 uniform M10.
The blade of strip adopts high-speed tool steel to make and the cutter hub of strip adopts carbon tool steel to make.
The beneficial effects of the utility model are: this softwood rotary cutter comprises blade and the cutter hub of strip, and the cutter hub of strip comprises knife back face, cutter side and cutter hub slightly face, and cutter side and the cutter hub angle slightly between face is the blade basil c of 17.5-18.5 degree; The blade of strip comprises blade face, blade slightly face and blade end face, and the angle of blade slightly between face and blade face is the little basil a in cutter top of 1 degree, and blade end face and the cutter hub angle slightly between face is the cutter top slightly little basil b in face of 1 degree.This rotary cutter improves the abrasion resistance properties of peeling knife edge, improves sharpness and the resistance to impact of blade cutting edge, has the effect smoothing press polish to thick wood surface to be processed simultaneously, improves the fineness of wood single-plate and the product quality grade of veneer.
Accompanying drawing explanation
Fig. 1 is a kind of structure chart of softwood rotary cutter.
Fig. 2 is the enlarged drawing of A in Fig. 1.
In figure: 1, cutter hub, 2, blade, 3, knife back face, 4, cutter side, 5, cutter hub slightly face, 6, blade face, 7, blade slightly face, 8, cutter hub screw, 9, knife back screw, 10, blade end face.
Detailed description of the invention
Fig. 1 and Fig. 2 shows a kind of softwood rotary cutter, adopts brazing to inlay steel integral by SKH51 high-speed tool steel between the cutter hub 1 that the blade 2 made and Q235B carbon tool steel make.The cutter hub 1 of strip comprises knife back face 3, cutter side 4 and cutter hub slightly face 5, and cutter side 4 and the cutter hub angle slightly between face 5 is blade basil C, and blade basil c is 18 ± 0.5 degree; The blade 2 of strip comprises blade face 6, blade slightly face 7 and blade end face 10, the angle of blade slightly between face 7 and blade face 6 is the little basil a in cutter top, the little basil a in cutter top is 1 degree, and blade end face 10 and the cutter hub angle slightly between face 5 is the cutter top slightly little basil b in face, and the cutter top slightly little basil b in face is 1 degree.Cutter hub 1 is provided with the cutter hub screw 8 of 54 uniform M16, and knife back face 3 is provided with the knife back screw 9 of 10 uniform M10.
Adopt technique scheme, softwood peeling knife blade adopts SKH51 high-speed tool steel, improves the abrasion resistance properties of peeling knife edge, improves the sharpness of blade cutting edge, add quality and the efficiency of rotary cut venner.Q235B carbon tool steel cutter hub, namely ensure that the support to blade, reduces again the difficulty of processing screw hole.Adopt the little basil a in cutter top and the cutter top slightly little basil b in face, improve resistance to impact and the sharpness of cutter top sword.The width of cutter top end face is 2-3mm, and surface roughness is Ra0.08, has the effect smoothing press polish to thick wood surface to be processed simultaneously, improves the fineness of wood single-plate and the product quality grade of veneer.
