The work to draw lines on mold cutter allows staff can be with same the work that knife draws lines and carves, Er Qie
When cutting wedge angle is worn, staff can make to cut wedge angle holding point by polishing to top surface and grinding surface
It is sharp.
The utility model is further arranged to: another contact position of the rake face and flank is set as reserved knife
Back.
By using above-mentioned technical proposal, reserved knife spine can be polished into a new blade by staff, allow work
The cutter that personnel use has more blades, to facilitate the cutting of staff to carve.
The utility model is further arranged to: the arrangement of the layout angle of the reserved knife spine and top surface and side edge and top surface
Angle is different.
By using above-mentioned technical proposal, staff is allow to polish the knife different from side edge at reserved knife spine
Sword makes the purposes of cutter wider.
The utility model is further arranged to: the thickness of the cutting portion is set as the half of shank diameter.
By using above-mentioned technical proposal, it both can be convenient staff and polished side edge, and also staff had been made to exist
It carries out being easier that blade is allowed to contact with mold cutter when cutting incised work.
The utility model is further arranged to: there are distances between the flank and the outer edge of knife handle.
By using above-mentioned technical proposal, when staff being allowed to carry out cutting incised work, knife handle will not be made to cutting portion
At interference.
The utility model is further arranged to: the in-plane of the rake face and the length direction of knife handle are parallel.
By using above-mentioned technical proposal, allow staff when side edge is polished again, it is only necessary to flank of polishing.
In conclusion the advantageous effects of the utility model are as follows:
1. the wedge angle for being used to cut engraved die is fabricated to blade-like by the way that a kind of cutter for carving die cutter is arranged,
Make staff more convenient when polishing cutter；

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1 is a kind of cutter for carving die cutter disclosed by the utility model, as shown in Figure 1 and Figure 2, including knife handle
1 and the cutting portion 2 that is provided on knife handle 1.Whole knife handle 1 is in round bar shape.Cutting portion 2 is by staff in one end of knife handle 1
Cutting polishing is formed.
As shown in Figure 1 and Figure 2, it is in half circular platform type, rake face 21, an arc surface type including a plane that cutting portion 2 is whole
The top surface 23 of flank 22 and cutting portion 2 far from 1 side of knife handle.Rake face 21 is contacted with flank 22.
The thickness of cutting portion 2 is set as the half of 1 diameter of knife handle, and exists between flank 22 and the outer edge of knife handle 1
Distance, so that flank 22 does not link together with 1 edge of knife handle.The in-plane of rake face 21 and the length direction of knife handle 1
In parallel.
In a contact position of rake face 21 and flank 22, grinding has grinding surface 24, so that rake face 21 and flank 22
Place formed a side edge 25 so that staff carry out mold cutter incised work when, with side edge 25 to mold cutter into
Row cutting engraving, is carved compared to being cut with point of a knife, is carried out after cutting engraving for a long time with side edge 25, staff can be square
Just efficiently side edge 25 is ground again.
Grinding surface 24 is arranged in flank 22, makes the grinding work of staff more convenient.
As shown in Figure 1 and Figure 2, top surface 23 is ground in the enterprising line tilt of cutting portion 2, makes shape between flank 22 and top surface 23
At a shear blade 26, allow staff is same when carrying out cutting incised work knife to be had different purposes, thus staff
It is more convenient to cut incised work, does not need multiple tool changing.And the side for contacting top surface 23 with flank 22 be lower than with it is preceding
Knife face 21 contact side, make top surface 23 to 22 side of flank tilt, be in same direction with grinding surface 24, allow shear blade 26 and
Side edge 25 links together, thus the cutting engraving of more convenient staff.
In addition, as shown in Figure 1 and Figure 2, a cutting wedge angle 27 is provided between shear blade 26 and side edge 25, wedge angle is cut
27 are located at the position that shear blade 26 is contacted with side edge 25, and when staff carries out cutting incised work, cutting point can be used
The work that angle 27 draws lines on mold cutter, allow staff can with same the work that knife draws lines and carves,
And when cutting wedge angle 27 is worn, staff can make to cut by polishing to top surface 23 and grinding surface 24
Wedge angle 27 keeps sharp.
As shown in Figure 1 and Figure 2, reserved knife spine 28, work are set by another contact position of rake face 21 and flank 22
Reserved knife spine 28 can be polished into a new blade by personnel, and the cutter for allowing staff to use has more blades, come side
Just the cutting engraving of staff.Wherein, staff can set the layout angle of reserved knife spine 28 and top surface 23 to
Side edge 25 is different with the layout angle of top surface 23, different from side edge 25 polish staff at reserved knife spine 28
Blade, make the purposes of cutter wider.
The implementation principle of the present embodiment are as follows: staff is when carrying out the work of cutting engraving, with side edge 25 or shear blade
26 pairs of mold cutters are carved, and after a protracted use, once side edge 25 or shear blade 26 are worn, staff can
Side edge 25 or shear blade 26 is set to keep sharp to be polished grinding surface 24 or top surface 23, and staff is to grinding
When face 24 or top surface 23 are polished, compared to polishing, point of a knife is more convenient to be easy.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
