Description
Technical field
The utility model is related to machining tool technical field more particularly to a kind of easy chip breaking reamers.
Background technology
In the low aluminium alloy valve opening finishing of fine aluminium or silicon content, particularly ream tolerance≤IT7, surface roughness≤
High-precision valve opening, the piston hole of Ra0.8, since reamer allowance is smaller, machined material is soft, viscous, is not easy chip breaking, during ream
The strip fines of appearance can be for a long time deposited in cutter chip space, and can be wrapped on cutter, scratch hole wall, cause the table in hole
Surface roughness can not be met the requirements, and spool or piston can be scratched in assembling process, causes poor sealing, oil leak pressure release shape occur
Condition, there are security risks.
Processing enterprise at present, the PCD cutters with chip breaking function used simply do chip-breaker (figure in PCD blade faces
1), there was only 0.5mm since PCD layer is thick, do chip-breaker on it, groove depth maximum is in 0.3mm, because raw material limitation, is done
Chip breaking groove deep is shallower, and chip cannot fracture completely, though certain chip breaking effect can be played, can't be fully solved chip breaking and ask
Topic.Also, because chip-breaker, close to cutting edge, cutter making difficulty is big, and such cutter making cost is also high, is susceptible to cutter not
It is good.There is chip-breaker, can also influence PCD intensity, easily collapse damage, cutter life is low.
Utility model content
The utility model provides a kind of easy chip breaking reamer to solve the problem above-mentioned.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of easy chip breaking reamer, including handle of a knife, knife
Body, blade one and blade two, cutter hub include being in turn connected into the forepart, middle part, rear portion of integral structure, and forepart, rear portion are
Cylindrical structure, middle part are staged cylindrical structure；Cutter hub is provided in the axial direction with two chip spaces, and two chip spaces are radially
Reverse symmetry is distributed；The angle of each chip space is 90 °, the chip space of each chip space forward end surface direction along a angles
It shrinks and forms ramp projections, form chip-breaking；Cutter hub front end face is opposite to be opened up there are two opening, and two openings are respectively with two
A chip space is connected；Reverse symmetry is equipped with blade one to two openings respectively, and two blades one lean out cutter hub front ends
Face；Reverse symmetry is equipped with blade two respectively on two chip spaces；One end of handle of a knife and the rear portion end face of cutter hub connect.
Further, the material of blade one and blade two is PCD.
Further, the size of two openings of cutter hub front end face：1mm<H<1.5mm.
Further, two openings respectively inlay and be welded with blade one by reverse symmetry.
Further, two blades one lean out the size of cutter hub front end face：0.15mm<L<0.3mm.
Further, reverse symmetry inlays and is welded with blade two respectively on two chip spaces.
Further, the outer diameter circle sword width dimensions of blade one：0.15mm<B<0.35mm.
Further, the outer diameter that two blades one are formed is D, cutter hub forepart diameter dimension：D-1.0mm<D1<D-0.7mm.
The utility model can thoroughly fracture chip, smooth discharge；PCD material is not destroyed, it is strong not influence cutting edge roundness
Degree, while the low manufacture cost of cutter, can be used steel cutter hub, you can meet the requirements.

Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in Fig. 2-Fig. 6, a kind of easy chip breaking reamer, including handle of a knife 1, cutter hub 2, blade 1 and blade 24, cutter hub 2 wraps
The forepart for being in turn connected into integral structure, middle part, rear portion are included, forepart, rear portion are cylindrical structure, and middle part is justified for staged
Column structure；Cutter hub 2 is provided in the axial direction with two chip spaces, and radially reverse symmetry is distributed two chip spaces；Each chip space
Angle for 90 °, end surface direction shrinks along a angles and forms ramp projections forward for the chip space of each chip space, is formed disconnected
Consider device to be worth doing；2 front end face of cutter hub is opposite to be opened up there are two opening, and two openings are connected respectively with two chip spaces, before cutter hub 2
The size of two openings of end surface：1mm<H<1.5mm；Two openings respectively inlay and be welded with blade 1 by reverse symmetry, and two
A blade 1 leans out the size of 2 front end face of cutter hub：0.15mm<L<0.3mm；Reverse symmetry edge is distinguished on two chip spaces
Scarfweld is connected to blade 24；The material of blade 1 and blade 24 is PCD, and the outer diameter of blade 1 justifies sword width dimensions：0.15mm<
B<0.35mm, the outer diameter that two blades 1 are formed are D, 2 forepart diameter dimension of cutter hub：D-1.0mm<D1<D-0.7mm；Handle of a knife 1
One end be connected with the rear portion end face of cutter hub 2.During PCD reamer machinings, generated chip by height for H notch to
Extension curling afterwards, when aluminium skimmings continue to crimp, and are contacted with the chip-breaking at 2 chip space of cutter hub, chip-breaking forces chip to become
Shape is forced to fracture, and original long bits is made to become short bits, will not wind, can smoothly be arranged by chip space very much on cutter hub 2
Go out, hole wall will not be scratched, improve the surface roughness in hole, can also meet the accuracy class requirement in hole easily, save substantial amounts of add
Between man-hour, the generation of defective products is reduced, reduces production cost.
