Abstract
The invention discloses a small-hole plastic part boring tool. The small-hole plastic part boring tool comprises a tool body and an edge part, wherein the front part of the tool body is recessed to form a concave part narrower than the tool body and used for avoiding in boring; the edge part is arranged at the front end of the concave part; a cutting edge of the edge part is outwards approached and projected to the center line of the tool body along the concave part to form an inequilateral cone; the gathered part of the cone to the tool body is an inwards recessed arc; the taper of the edge part at the cutting edge is decreased; the taper of the edge part at the cutting edge is in a range of 7-10 degrees; the edge place of the edge part is projected at the widest place of the tool body; and the edge part adopts a material of a hard alloy. Compared with the prior art, the small-hole plastic part boring tool can solve the problems of traditional boring tools unsuitable for processing small-hole workpieces and influence on processing quality.
Description
Technical field
The present invention relates to plant equipment manufacturing technology field, especially a kind of boring of the boring machine for machining small workpiece
Knife.
Background technology
The boring cutter of existing boring machine, generally comprises cutter hub and blade part, and cutter hub is vertical bar, and blade part is in cone, or the edge of a knife
Outer incline of the portion to the cutter hub of vertical bar.Lathe tool of the blade part in cone, the little hole workpiece of turning are sharp due to cutting edge, and turning is convenient,
But the turning time is soon, easily abrasion or fracture；Another kind of blade part thinks inclined outside cutter hub, and cutting edge is wider, the difficult mill of comparison,
Fracture is not easy to, the turning time is more long but stronger for little hole workpiece toughness, easily extruding clout produces planted agent during blade boring
The deformation that power is concentrated.So that a kind of boring cutter for being suitable for little hole workpiece of design, to meet the needs in market.
The content of the invention
Problem to be solved by this invention is to provide a kind of aperture working of plastics boring cutter, is not suitable for processing to solve existing boring cutter
Little hole workpiece, affects the problem of crudy.
In order to solve the above problems, the technical scheme is that：This aperture working of plastics boring cutter includes cutter hub and blade
Portion, the cutter hub front portion be concavely formed width dimensions less than the cutter hub width dimensions for bore hole when the recess that avoids,
, located at the front end of the recess, the cutting edge of the blade part is along the recess outwards and in the cutter hub for the blade part
Heart line draw close it is prominent in inequilateral cone, the cone to the cutter hub furlling part in the arc being inwardly recessed, the knife
Blade taper at the cutting edge diminishes, the blade part in the taper at cutting edge in the range of 7 ° to 10 °, the knife of the blade part
The widest part of the cutter hub is protruded from sword, the material of the blade part is hard alloy.
In above-mentioned technical proposal, more specifically scheme can be：The material of the blade part is diamond.
As a result of above-mentioned technical proposal, the present invention is had the advantages that compared with prior art：
The special design of the blade part of this aperture working of plastics boring cutter, cutting edge are drawn close outwards and to cutter hub centrage along recess
It is prominent in inequilateral cone, the cone is bored to the cutter hub furlling part at cutting edge in the curved knife blade being inwardly recessed
Degree diminishes, and makes the edge of a knife sharp, it is to avoid production larger cutting stress, and blade part has enough intensity, and cutting edge is protruded from
The widest part of cutter hub, allows cutting edge to facilitate bore hole.
Description of the drawings
Fig. 1 is the front view of the embodiment of the present invention；
Fig. 2 is the top view of the embodiment of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the embodiment of the present invention is described in further detail：
This aperture working of plastics boring cutter as shown in Figure 1 and Figure 2, it includes cutter hub 1 and blade part 3, and cutter hub 1 is anterior recessed
Formed width dimensions less than cutter hub 1 width dimensions for bore hole when the recess 2 that avoids, blade part 3 is before recess 2
End, the cutting edge 3-1 of blade part 3 along recess 1 outwards and to draw close prominent to 1 centrage of cutter hub be in inequilateral cone, cone to
In the arc that is inwardly recessed, the taper at the cutting edge 3-1 of blade part 3 diminishes 1 furlling part of cutter hub, and blade part 3 is at cutting edge 3-1
Taper angles A=8 °, make the edge of a knife sharp, it is to avoid production larger cutting stress, and blade part has enough intensity.Blade part 3
Blade 3-1 protrudes from the widest part of cutter hub 1, and the material of blade part 3 is hard alloy, allows cutting edge to facilitate bore hole.
In other embodiments, the material of cutting portion can also select diamond, and at the cutting edge of blade part, taper can be
Any one numerical value between 7 ° to 10 °.
Claims (2)
1. a kind of aperture working of plastics boring cutter, includes cutter hub and blade part, it is characterised in that：The cutter hub front portion is concavely formed width
Degree be smaller in size than the cutter hub width dimensions for bore hole when the recess that avoids, the blade part is located at the recess
Front end, the cutting edge of the blade part along the recess outwards and to draw close prominent to the cutter hub centrage be in inequilateral cone,
The cone to the cutter hub furlling part in the arc that is inwardly recessed, blade part taper at the cutting edge diminishes, described
Blade part protrudes from the most wide of the cutter hub in the taper at cutting edge in the range of 7 ° to 10 ° at the blade of the blade part
Place, the material of the blade part is hard alloy.
2. aperture working of plastics boring cutter according to claim 1, it is characterised in that：The material of the blade part is diamond.
