Description

Trimming knife for wooden door

Technical Field

The utility model relates to the field of cutters, in particular to a trimming cutter for wooden doors.

Background

Wooden furniture is an indispensable life tool in people's daily life, along with people's life quality's promotion, in the in-process of processing wooden furniture, because the different design needs to require to different anchor clamps, often need set up the recess of circular arc to ligneous border.

For example, application number 202021791226.5 discloses a fillet deburring sword for timber, the crookedness cooperation tool bit of first side is crooked edge of a knife to make when to the plank deburring, the saw-dust that the tool bit will produce is evenly taken into the discharge groove in, along with the tool bit rotates, the saw-dust is discharged by the discharge groove, and first tangent plane, second tangent plane and the third tangent plane that connect gradually are smoother, make the effect of centrifugal force down the saw-dust when discharging, the second side is difficult for causing the jam to the discharge path of saw-dust, the saw-dust is difficult for piling up the deburring that influences the tool bit to the plank.

Above-mentioned in, carry into the blowpit to the piece that produces when the plank deburring in, discharge the saw-dust again, because the deburring sword is continuous to the in-process of operating timber, when cutting edge portion and plank area of contact are great, the piece is blocked up in the vicinity of cutter and machined surface easily, because of the route of blowpit is limited for a large amount of piece are piled up on the blowpit, are difficult to discharge through the second side, influence even to the machining efficiency of plank.

Drawings

FIG. 1 is a perspective view of an embodiment of the present utility model;

fig. 2 is a partial schematic view of the present utility model.

Tool bit 1, cutter arbor 2, backup pad 3, blade 4, discharge groove 5, discharge groove 6, fixed column 7, guiding gutter 8, ramp 9, slide opening 10, inclined plane knife tip 11, domatic 12, net face 13.

Description of the embodiments

Embodiments of the present utility model will be further described with reference to fig. 1 to 2.

The specific structure of this embodiment is as follows: the cutter comprises a cutter head 1 and a cutter bar 2 connected with the cutter head 1, wherein the cutter head 1 comprises a supporting plate 3 and a cutter blade 4, the cutter blade 4 is provided with two inclined plane cutter tips 11, the two cutter tips are respectively arranged on one side of the supporting plate 3, and one side of the cutter blade 4 is an inclined plane, so that the inclined plane cutter tips 11 and a wood plate are cut.

Four discharging grooves 5 which are transversely distributed and three discharging grooves 6 which are longitudinally distributed are formed in the outer wall of the supporting plate 3, the discharging grooves 5 are arranged on one opposite side face of the supporting plate 3, the discharging grooves 5 are arranged on the other opposite side face of the supporting plate 3, a slope 12 which is inclined from the inner wall of the discharging groove 6 to the notch of the discharging groove 6 is arranged on the discharging groove 6, and a net surface 13 is arranged on the slope 12.

During the continued operation of the knife on the timber, a portion of the chips are placed in the discharge chute 6, rotated on the sloping surface 12 by the rotating chips and the mesh surface 13 is in frictional contact, and finally rotated out of the discharge chute 6 by the rotation.

The cutter bar 2 is fixedly sleeved with a fixing column 7, and the fixing column 7 is arranged above the cutter bar 2 and is fixed with the supporting plate 3.

Four guide grooves 8 communicated with the discharge groove 5 are formed in the fixing column 7, two ramps 9 which are inclined from the lower port of the guide groove 8 to the bottom end of the cutter bar 2 are arranged on the guide groove 8, chips can conveniently flow from the guide groove 8 to the ramps 9, and finally the chips slide out from the ramps 9.

So that the chips can flow into the guide groove 8 through the discharge groove 5 and finally slide into the through holes from the ramp 9, and can also flow into the guide groove 8 through the discharge groove 5, and the guide groove 8 directly slides out from the sliding holes 10, so that the chips have two chip discharging paths in the discharge groove 5.

Four slide holes 10 which surround the peripheral wall by taking the bottom surface of the cutter bar 2 as a reference surface are arranged on the cutter bar 2, so that a large amount of scraps can conveniently flow out of the slide holes 10.

The cutter bar 2 and the cutter head 1 rotate, the bevel cutter tip 11 trims the wood board, one part of generated scraps is driven into the discharge chute 6, the scraps are in friction contact with the net surface 13 in the slope 12, the scraps are discharged through rotation, and the other part of the scraps are driven into a plurality of transversely distributed discharge chutes 5.

The piece is discharged from ramp 9 through guide way 8, and when inclined plane knife tip 11 and plank area of contact are great, the piece that produces can be by two exhaust modes, increased piece exhaust route for the piece is difficult to block up near cutter and machined surface, and then improves plank machining efficiency.

The above description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model, but one skilled in the art can make common changes and substitutions within the scope of the technical solution of the present utility model.
