Abstract
The utility model relates to a novel platen type adjustable single edge reamer, belonging to the reamer with an adjustable diameter. The utility model is redesigned by geometric parameter on the basis of the existing platen type adjustable single edge reamer; a rake angle (crater) which is opened on a blade along all edge length is changed to an edge inclination angle which is only opened on the section of the cutting place of the chipping allowance of the cutting end arranged on the blade. The edge inclination angle is provided with a combining rake angle which is composed by the rake angle arranged on the blade and a rake angle arranged at an upper blade groove of the reamer body; a proper main offset angle is selected. The platen type adjustable single edge reamer has the advantages of compact structure, good cutting ability, and stable dimension of the processing parts. The utility model solves the problems that the edge of the imported single edge reamer is tripped, and the reamer body is twisted, etc., and has popularized prospect in the mechanical process field.
Description
The utility model belongs to the adjustable reamer of reamer diameter.
Presser type single-blade expansion reamer has lot of advantages in reamer, as compact conformation, and a tool changing sheet during cutting is used, cutter hub can continue to use size adjustable, thereby technical advanced person, the single-blade expansion reamer of West Germany for example, being commonly called as the precious reamer of wheat is exactly the most familiar representative products.This reamer is to be assembled by cutter hub and blade, and blade is placed in the insert groove of cutter hub, pushes down blade with pressing plate, and pressing plate compresses with bolt.Although this reamer advantage is many, it is pinching blade in use often to occur, and tipping and chip removal are bad to cause fraising to stop up problems such as turning round bad cutter hub.
The purpose of this utility model provides a kind of novel presser type single-blade expansion reamer that has improved.
The utility model is that the geometric parameter redesign forms on the basis of existing presser type single-blade expansion reamer.Existing single-blade expansion reamer, its blade has anterior angle (crescent moon low-lying area) on long along full sword, and smear metal can not be discharged smoothly, often causes forging a knife, twists bad cutter hub because of chip removal is bad.Open anterior angle along full blade in addition, edge strength descends, and can not get guaranteeing owing to opening its blade linearity of anterior angle simultaneously, produces vibration, high some place tipping during cutting.The utility model is the above-mentioned anterior angle of blade (crescent moon low-lying area) only to be changed in one section of cutting place of the cutting end of blade chipping allowance open a cutting edge inclination λ, and have anterior angle γ on one section the blade in the cutting edge inclination front, the insert groove of cutter hub is provided with another anterior angle γ ' when assembling with blade, γ and γ ' composition combination anterior angle, the setting of combination anterior angle strengthens anterior angle, not sticking cutter helps eliminating BUE under the high-speed cutting situation.Take into account surface quality for enhancing productivity, and avoid producing vibration and suitably strengthen tool cutting edge angle.
Accompanying drawing is novel presser type single-blade expansion reamer schematic diagram, 1-carbide chip among the figure, 2-cutter hub, 3-bolt, 4-pressing plate, 5-fore-set (2), 6-bolt (2), 7-block, 8-guide block (2).
Carbide chip 1 is placed in the insert groove of cutter hub 2, pushes down blade with pressing plate 4, and pressing plate compresses with bolt 3 or unclamps, and adjusting the reamer diameter dimension is to make fore-set 5 do rectilinear motion by bolt 6 rotations, forces blade to move up.On cutter hub, be provided with guide block and play centralizing function.Block blocks blade start-stop action and uses.Blade is provided with cutting edge inclination λ in cutting place of front end chipping allowance, large and small and the positive and negative bits that go out that can control cutting of cutting edge inclination move towards, for example when the processing through hole, selected for use negative side rake to make smear metal discharge chip removal under the abbreviation, when processing blind hole, needed chip removal then to select positive cutting edge inclination etc. for use with cutting direction.Be located at the cutting edge inclination λ on the blade and have anterior angle γ, when making novel presser type single-blade expansion reamer ream cutting brisk, can be rolled into the long bits of the very little web-like of radius to smear metal again and discharge from work surface.The distribution of tool cutting edge angle and cutting force, machining accuracy, the durability of heat radiation and cutter all has confidential relation.The tool cutting edge angle of reamer is one sometimes can be had two or more sometimes.It is φ and φ ' that the utility model is selected with two.For example the utility model is at processing 20C
rM
nThe bent axle of Ti material, during through hole, two tool cutting edge angles are selected for use less than 10 °.
Novel single-blade expansion reamer is the carbide alloy machine reamer, has compact conformation, cutting ability is good in the use, the accessory size of processing is stable, chip removal is set well thereby not only can have satisfied production requirement of not pinching not tipping cutting edge inclination, the single-blade expansion reamer that is better than import technically significantly is being the future that popularization is arranged aspect the processing of machining mesopore.
Claims (2)
1, novel presser type single-blade expansion reamer is made up of cutter hub [2], blade [1], pressing plate [4], blade is placed in the insert groove of cutter hub, push down with pressing plate, pressing plate compresses with bolt [3], the reamer diameter has guide block [8] to set upright by the upper and lower adjustable cutter hub of bolt [6] fore-set [5] [2], the cutting end that it is characterized in that said blade [1] has cutting edge inclination λ, has the combination anterior angle.
