Abstract
The utility model provides a kind of small tooth pitch side set flat blade, including cutter hub and hard alloy, and multiple cutters tooth are evenly arranged with along cutter hub axis and circumference, tooth socket is formed between the adjacent cutter tooth of axis, mounting groove is provided on the cutter tooth, it is characterised in that：The hard alloy is welded in mounting groove to form side set structure at interval of a cutter tooth along axis and circumferencial direction, the width of the tooth socket is 2mm, and the cutter hub tooth width is 5mm, and the hard alloy width is 8mm.Cutter hub space width reduces, and the distance that hard alloy stretches out cutter hub can be made to reduce, to make side set flat mouth in cutting, hard alloy vacantly measures reduction, stress point concentrates on cutter hub so that hard alloy is more firm, to achieve the effect that hard alloy is not easy to interrupt, falls off.
Description
Technical field
The utility model is related to timber process tool fields, and in particular to a kind of small tooth pitch side set flat blade.
Background technology
In timber process tool, the screw type flat blade simple production process of side set flat blade relatively at present on the market is practical
Property can reach screw type cutter effect, and alloy has appearance bits inclined-plane to facilitate chip removal.But carpenter Furniture Factory cuts to timber
When cutting milling type, big spacing side set flat blade（Space width>4mm, cutter tooth are wide>11mm, the width of hard alloy>16mm）It is susceptible to
Alloy integrally falls off, be susceptible to during client's use get stuck, alloy fracture phenomena such as, not only make the service life of cutter big in this way
It shortens greatly, it is easier to cause safety accident.
Utility model content
The utility model provides a kind of small tooth pitch side set flat blade, it is intended to improve existing big spacing side set flat blade, will put down
The tooth pitch of mouthful knife becomes smaller, and the width of every tooth also becomes smaller, and such cutter becomes more firm, alloy be less prone to fall off, crackle
Phenomena such as.
In order to realize the purpose of this utility model, intend using following technical scheme：
A kind of small tooth pitch side set flat blade, including cutter hub and hard alloy, are uniformly arranged along cutter hub axis and circumference
There are multiple cutters tooth, form tooth socket between the adjacent cutter tooth of axis, mounting groove is provided on the cutter tooth, it is characterised in that：Along axis
The hard alloy is welded in mounting groove to form side set structure, the width of the tooth socket at interval of a cutter tooth with circumferencial direction
Degree is 2mm, and the cutter hub tooth width is 5mm, and the hard alloy width is 8mm.
Further, it is the cutting effect for obtaining best, the cutter tooth quantity on the cutter hub circumference is 6.
Further, the lower mouth mill of edged surface has ramp down angle before the hard alloy.
Further, the cutter hub both ends are equipped with end face step, and end face step height is generally 1mm, and surface is machined to light
It is bright, the beauty of cutter can be improved.
The utility model has the beneficial effects that：
1, side set flat blade practical performance achievees the effect that screw type cutter, and than the production technology letter of screw type flat blade
Single, production cost is lower；
2, since cutter hub tooth socket is 2mm（Before>4mm）, the cutter hub facewidth is 5mm（Before>11mm）, such hard alloy
Width is also decreased to 8mm therewith（Before>16mm）, the reduction of cutter hub space width, can make hard alloy stretch out cutter hub away from
From reduction, to make side set flat mouth in cutting, hard alloy vacantly measures reduction, and stress point concentrates on cutter hub so that hard
Alloy is more firm, to achieve the effect that hard alloy is not easy to interrupt, falls off；
3, mouth mill has ramp down angle under edged surface before carbide cutting so that timber can be by by chamfer mouth when being cut
Discharge in time, thus the phenomenon that not causing to get stuck.
Description of the drawings：
Fig. 1 is the axis structure schematic diagram of the utility model；
Fig. 2 is the radial structure schematic diagram of the utility model；
Fig. 3 is the partial enlarged view of the utility model radial structure schematic diagram.
In all the appended drawings, identical reference numeral is used for indicating identical element or structure, wherein：
1- cutter hubs, 2- hard alloy, 3- cutters tooth, 4- tooth sockets, the end faces 5- step, 6- mounting holes, 21- hard alloy anterior angles
Face, 22- ramp downs angle.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1, 2, 3, a kind of small tooth pitch side set flat blade, it is characterised in that：Including cutter hub 1 and hard alloy 2, edge
Multiple cutters tooth 3 are evenly arranged on 1 axis of cutter hub and circumference, 3 quantity of cutter tooth is six on the circumference of optimized cutting effect, edge
Tooth socket 4 is formed between the adjacent cutter tooth of axis 3, mounting groove is milled on cutter tooth 3, along axis and circumferencial direction at interval of a cutter tooth 3
Hard alloy 2 is welded in mounting groove to form side set structure, welding form can guarantee that hard alloy 2 and the connection of cutter hub 1 are strong
Degree.4 width of tooth socket above-mentioned is 2mm, and 3 width of cutter tooth is 5mm, and the width of such hard alloy 2 is also decreased to 8mm, tooth socket 4 therewith
The reduction of width can be such that the distance that hard alloy 2 stretches out cutter hub 1 reduces, to make side set flat mouth in cutting, hard alloy
2 hanging amounts reduce, and stress point concentrates on cutter hub 1 so that hard alloy 2 is more firm, is not easy to beat to reach hard alloy 2
The effect break, to fall off.The lower mouth mill of edged surface 21 has ramp down angle 22 before hard alloy 2 so that timber passes through chamfering when being cut
22 mouthfuls can be discharged in time, thus the phenomenon that not causing to get stuck.
In the present embodiment, cutter hub 1 is machined with end face step 5, and end face step 5 is highly generally 1mm, and surface is machined to light
It is bright, improve the beauty of cutter.
In the present embodiment, cutter hub 1 is provided with mounting hole 6, the axis connection that cutter passes through mounting hole 6 and cutting machines.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiments of the present utility model only, not to
Limitation the utility model, all any modification, equivalent and improvement made within the spirit and principle of the present invention etc.,
It should be included within the scope of protection of this utility model.
