Description

The undersized log saw lumber cutter head of chipping

The utility model is the parts that belong to the machine tool device of the saw lumber of chipping.

At present, domestic processing undersized log adopts the saw lumber combination machine of chipping, and the critical piece cutter head of this equipment generally is by the cutterhead that has the straight knife groove vertically, and 2-4 the single-blade mouth, and linear pattern long blade and saw blade constitute.This cutter head cutting way is to belong to end grain cutting, cutting edge rift grain extruding lumber fibre, damage fibre strength.Two main surfaces of wood chip are that shear fracture forms under the effect of rake face pressure, and the thickness of not only rough surface, and wood chip and geometry be difficult to guarantee that chip quality is poor, can only be as the Wood-based Panel Production raw material, can not be used for papermaking.In addition, lumber recovery is low, influences wood utilization rate and economic benefit.

The purpose of this utility model is a kind of undersized log of design saw lumber cutter head of chipping, undersized log sapwood through peeling partly can be whittled into technological wood chips with this cutter head, the mid portion sawing becomes square bar or sheet material, and wood chip can be used to produce wood-based plate, and be the quality raw materials of papermaking, the economic benefit height.

The utility model mainly by: cutterhead 1, tool rest 2, chip breaking plate 3, blade 4, cover plate 5, saw blade 6, adjusting washer (disk) 7, axle head clamp nut 8 are formed, as shown in Figure 1; It is characterized in that: in cutterhead 1 truncated cones dignity upper edge radially by two equidistant spiral of Archimedes a plurality of cutter grooves that distribute, the cutter fluted shaft reduces to small end face successively to the large end face of the degree of depth by cutterhead 1, tool rest 2 has the fixing inclined-plane of blade 4 and a boss of positioning blade 4 adjusted, tool rest 2 is fixed in the cutter groove of cutterhead 1 with screw, blade 4 has a handle of a knife, two cutting edges, main sword is parallel to the inclined-plane of cutterhead 1, side edge is with respect to angle of cutterhead 1 end slope, blade 4 is fixed on the inclined-plane of tool rest 2 with screw, blade 4 radially is being arranged on the cutterhead 1 by equidistant spiral of Archimedes in the cutter groove, chip breaking plate 3 is screwed on the rake face of blade 4, use key, adjusting washer (disk) 7, axle head clamp nut 8 connects with main shaft, forms the undersized log saw lumber cutter head of chipping.

The chip operation principle of saw lumber cutter head of undersized log: cutterhead 1 is frustoconical sheets, and radially by two equidistant spiral of Archimedes, 14 the cutter grooves that distribute, blade 4 is fixed in the cutter groove by tool rest 2, and the cutter slot tail is a plane, so that the tool rest radial location.The axial depth of cutter groove can be processed thickness according to wood chip and be reduced successively to small end with the big end of cutterhead, to guarantee the thickness uniformity of wood chip.The axial restraint of cutterhead 1 adopts cone match, the central shaft hole that is cutterhead 1 is a taper seat, be linked together with main shaft with key, axle head clamp nut 8, saw blade 6 usefulness adjusting washer (disk)s 7, screw are fixed on the small end face of cutterhead 1, the small end face that makes cutterhead 1 is a plane, when cutting, have guiding and positioning action, as shown in Figure 1.Tool rest 2 has the inclined-plane C and the boss D of a dress blade 4, as shown in Figure 3, and the angle parameter when inclined-plane C can provide the cutting edge of blade 4 to cut; Boss D is convenient to blade 4 radial locations and is born cutting moment; On the rake face of tool rest 2 and blade 4 surface that links is an inclined-plane E, is convenient to wood chip and discharges smoothly.Blade 4 has two cutting edges, promptly main sword A and side edge B, as shown in Figure 4; The end face of the parallel cutterhead 1 of main sword A is parallel to the lumber fibre cutting, wood chip can be separated from the timber main body; Side edge B is with respect to angle of cutterhead 1 end slope, the also main relatively sword A angle that tilts, and, play the cut staple effect with respect to the lumber fibre direction angle that tilts.Have slotted hole on blade 4 handle of a knifes,, reach and regulate dried thickness and prolong cutter life so that regulate the cutting edge overhang along tool rest 2 inclined-plane C.

The utility model compared with prior art, because blade is fixed in the cutter groove of cutterhead by tool rest, the cutter groove radially is distributed on the cutterhead by two equidistant spiral of Archimedes, and the axial depth of cutter groove can be processed thickness according to wood chip and be reduced successively to small end from the big end of cutterhead.Blade is divided into main sword and side edge, and main sword is parallel to the fiber separation wood chip, side edge inclination cut staple.Use this cutter head the undersized log sapwood through peeling partly can be whittled into technological wood chips, simultaneously the mid portion sawing is become square bar or sheet material.The wood chip of being processed not only can be used for producing wood-based plate, and is the quality raw materials of papermaking, and the lumber recovery height is good in economic efficiency.

Embodiment of the present utility model:

The undersized log saw lumber cutter head of chipping mainly is made up of as shown in Figure 1 cutterhead 1, tool rest 2, chip breaking plate 3, blade 4, cover plate 5, saw blade 6, adjusting washer (disk) 7, axle head clamp nut 8.Wherein screw, bolt, nut, key adopt standard component.Cutterhead 1 usefulness ZG35 is through casting, finish turning, groove milling, and radially by 14 cutter grooves of equidistant spiral of Archimedes distribution, the cutter fluted shaft reduces to small end from the big end of cutterhead according to wood chip processing thickness successively to the degree of depth in truncated cones dignity upper edge.Tool rest 2 usefulness Q235-A forges, brill forms, and tool rest 2 has two installing holes, inclined-plane C, the boss D of blade 4 is installed and is convenient to arrange wood chip face E for one, as shown in Figure 3.Chip breaking plate 3, cover plate 5, adjusting washer (disk) 7 usefulness 35 steel plates process.Blade 4 can be solid tool steel or cutter hub ordinary steel and the cutting edge seting welding carbide, and handle of a knife has two slotted holes to be used for fixing blade 4 usefulness, main sword A, side edge B, and two screws are used for fixing chip breaking plate 3.Saw blade 6 adopts outsourcing piece.

Chip breaking plate 3 is screwed on blade 4, blade 4 is fixed on the C face of tool rest 2, tool rest 2 is fixed on the cutter groove place of cutterhead 1 with bolt, nut with cover plate 5, screw; Saw blade 6 is screwed on cutterhead 1 small end face, cutterhead 1 is connected the composition undersized log saw lumber cutter head of chipping with key, adjusting washer (disk) 7, axle head clamp nut 8 with main shaft.

When installing with main shaft, adjust the thickness of adjusting washer (disk) 7, to guarantee axle head clamp nut 8 and saw blade in same sagittal plane, make the cutterhead end face when cutting, have the guide-localization effect.
