Abstract
The utility model discloses a reamer, including stalk portion, neck and head, the stalk portion passes through the neck and connects the head, is equipped with a plurality of grooves on the same circumference of head, and every inslot all is provided with the cutting part, is equipped with the cutting edge on the cutting part, a plurality of grooves are branch settings such as non -. The utility model discloses a resonance can not take place for reamer in high -speed cutting process.
Description
Technical field
This utility model Machining Technology field, is specifically related to a kind of reamer.
Background technology
Reamer is to have one or more cutter tooth, in order to excise the rotary cutter of hole machined surface thin metal layer；Reamer is mainly used in reaming or repaiies hole, can work with manual operation or be arranged on drilling machine；But at present reamer exists following point: after 1) the tail flat package of handle of a knife enters machine tool chief axis, if the flat off normal of tail produces handle of a knife and interferes, the most processed hole back aperture that ream increases, and greatly, surface flatness is the highest for error；2) when fraising, if reaming allowance is excessive or the amount of feeding is excessive, when rotating speed is too high, it is easily caused breaking；3) groove on current reamer designs for decile, forms resonance during adjusting rotary cutting, easily causes reamer fracture.
Summary of the invention
For the problems referred to above, this utility model provides a kind of reamer that resonance will not occur in high-speed machining process.
The technical scheme solving above-mentioned technical problem is as follows:
Reamer, including shank, cervical region and head, shank connects head by cervical region, and the same circumference of head is provided with multiple groove, is provided with blade in each groove, and blade is provided with cutting edge, and the plurality of groove is that non-decile is arranged.
Preferably, described groove is 6, the respectively first groove, the second groove, the 3rd groove, the 4th groove, the 5th groove, the 6th groove.
Preferably, the radian shared by described first groove is 60 °, and the radian shared by the second groove is 55 °, and the radian shared by the 3rd groove is 65 °, and the radian shared by the 4th groove is 65 °, and the radian shared by the 5th groove is 59 °, and the radian shared by the 6th groove is 56 °.
Preferably, shank, cervical region and head are provided with inlet opening, at least provided with an apopore connected with inlet opening on described head.
Preferably, described apopore is multiple, and two of which is a pair, connects with inlet opening after lining up V-shaped.
Preferably, the ligament width of described cutting edge is the 2.5 3% of head diameter.
Preferably, the end of described head is provided with chamfering, and the size of this chamfering is 40 50 °, and the width of chamfering is 0.05 0.1mm, and the relief angle of chamfering is 10 14 °.
This reamer is the overall reamer using Hardmetal materials to make.
Advantage of the present utility model is: the most the plurality of groove is after non-decile is arranged, and reamer has avoided the formation of resonance when high speed rotating, it is therefore prevented that cracking of cutter.After head is provided with chamfering, solve position height deviation and bell-mouthed problem that preceding working procedure causes.Being provided with inlet opening apopore, make cutter can pass through water cooling in the course of processing, interior cooling makes the iron filings and the heat that produce in working angles get rid of in time, it is to avoid hole wall scratches and forms the phenomenon of shrinkage cavity.
