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 cutter of the boring machine for machining small workpiece.
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 cone, or blade portion is to the outer incline of the cutter hub of vertical bar.Blade part is the lathe tool of cone, the little hole workpiece of turning due to cutting edge sharp-pointed, turning is convenient, but the turning time is soon, easily wearing and tearing or fracture; Another kind of blade part thinks the outer incline of cutter hub, and cutting edge is wider, more difficult mill, also not easy fracture, and the turning time is comparatively of a specified duration, but comparatively strong for little hole workpiece toughness, easily extrudes the distortion that clout produces stress concentration during blade boring.Thus need to design a kind of boring cutter being suitable for little hole workpiece, to meet the needs in market.
Summary 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 machining small workpiece, affects the problem of crudy to solve existing boring cutter.
In order to solve the problem, technical scheme of the present invention is: this aperture working of plastics boring cutter includes cutter hub and blade part, described cutter hub front portion is concavely formed the recess for dodging during bore hole that width dimensions is less than described cutter hub width dimensions, described blade part is located at the front end of described recess, the cutting edge of described blade part along described recess outwards and to draw close outstanding to described cutter hub center line be inequilateral cone, described cone to described cutter hub furlling part in the arc be inwardly recessed, described blade part diminishes in cutting edge place tapering, the tapering of described blade part in cutting edge place is in the scope of 7 ° to 10 °, the blade place of described blade part protrudes from the widest part of described cutter hub, the material of described blade part is carbide alloy.
In technique scheme, more specifically scheme can be: the material of described blade part is diamond.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The design that the blade part of this aperture working of plastics boring cutter is special, cutting edge along recess outwards and to draw close outstanding to cutter hub center line be inequilateral cone, diminishing in cutting edge place tapering in the curved knife blade be inwardly recessed to described cutter hub furlling part of described cone, make the edge of a knife sharp, avoid the cutting stress that production is larger, and blade part has enough intensity, cutting edge protrudes from the widest part of cutter hub, makes cutting edge facilitate bore hole.
Accompanying drawing explanation
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.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
As Fig. 1, this aperture working of plastics boring cutter shown in Fig. 2, it includes cutter hub 1 and blade part 3, cutter hub 1 front portion is concavely formed the recess 2 for dodging during bore hole that width dimensions is less than cutter hub 1 width dimensions, blade part 3 is located at the front end of recess 2, the cutting edge 3-1 of blade part 3 along recess 1 outwards and to draw close outstanding to cutter hub 1 center line be inequilateral cone, cone to cutter hub 1 furlling part in the arc be inwardly recessed, blade part 3 diminishes in cutting edge 3-1 place tapering, blade part 3 is in taper angles A=8 ° at cutting edge 3-1 place, make the edge of a knife sharp, avoid the cutting stress that production is larger, and blade part has enough intensity.The blade 3-1 of blade part 3 protrudes from the widest part of cutter hub 1, and the material of blade part 3 is carbide alloy, makes cutting edge facilitate bore hole.
In other embodiments, the material of cutting portion can also select diamond, and the cutting edge place tapering of blade part can be any one numerical value between 7 ° to 10 °.
Claims (2)
1. an aperture working of plastics boring cutter, include cutter hub and blade part, it is characterized in that: described cutter hub front portion is concavely formed the recess for dodging during bore hole that width dimensions is less than described cutter hub width dimensions, described blade part is located at the front end of described recess, the cutting edge of described blade part along described recess outwards and to draw close outstanding to described cutter hub center line be inequilateral cone, described cone to described cutter hub furlling part in the arc be inwardly recessed, described blade part diminishes in cutting edge place tapering, the tapering of described blade part in cutting edge place is in the scope of 7 ° to 10 °, the blade place of described blade part protrudes from the widest part of described cutter hub, the material of described blade part is carbide alloy.
2. aperture working of plastics boring cutter according to claim 1, is characterized in that: the material of described blade part is diamond.
