Description
Technical field
Machining tool technical field is the utility model is related to, more particularly to a kind of high-density alloy vibrationproof boring cutter bar knot
Structure.
Background technology
Bore hole is to forging hole, casting out hole or drilling bore hole is processed further.Bore hole can expand aperture, improve precision, subtract
Small surface roughness, it can also preferably correct the deflection of original axially bored line.Bore hole is divided into general bore hole and deep hole bore hole, typically
Bore hole can meet processing request substantially in engine lathe, the conventional steel knife bar of assembling.Deep hole bore hole then needs special depth drill
Boring machine, the big cutter of draw ratio need to be typically used, knife bar overhanging distance, causes cutting stability to reduce, easily produces vibration,
Higher requirement is proposed to the vibration resistance of boring cutter bar.Currently used boring cutter bar material is mostly steel or hard alloy, steel
In process, easy stress is bent boring cutter bar processed, especially in deep hole machining, because knife bar draw ratio is big, and deflection
Bigger, when causing processing, cutter easily vibrates, and directly influences the dimensional accuracy of work piece, and machined surface quality
It is not high, requirement of the workpiece to dimensional accuracy and surface smoothness can not be met.And although hard alloy boring cutter bar rigidity is preferably,
Cemented Carbide Hardness is high, and fragility is big, processing difficulties, and manufacturing cost is higher.In addition, when carrying out bore hole using boring cutter, due to iron filings
Splashing, it is easy to the inwall in the hole to processing causes to scratch.
Utility model content
In view of the above-mentioned problems, the utility model provides, a kind of knife bar rigidity is high, prevents from scratching the boring cutter bar of processing hole inwall
Structure.
To reach above-mentioned purpose, using following technical scheme：
A kind of high-density alloy vibrationproof boring cutter bar structure, including cutter head and knife bar, the leading section of cutter head, which is provided with, to be used to install
The dress knife section of boring blade, dress knife section include the main dress knife face corresponding with boring cutter plate shape and prolonged backward by main dress knife face
The transition face stretched, the cutter head are alloy tool steel bit, and the knife bar is high-density alloy knife bar, and cutter head and knife bar pass through welding
Mode is docked, and the section of butt weld is V-shaped, is provided with inflatable mouth on the transition face, and the is provided with the axle center of cutter head
One insufflation channel, the second insufflation channel is provided with the axle center of knife bar, one end of the first insufflation channel is connected with the second insufflation channel
Logical, the other end of the first insufflation channel is connected with inflatable mouth.
Further, the main dress knife face include a tip corresponding with boring blade point of a knife, one with the master of boring blade
Rear edge corresponding to knife face afterwards, the inflatable mouth and the tip, rear edge are point-blank.
Further, the main dress knife face is provided with the Cooling Holes corresponding with position of tool tip after boring blade.
The structure adds steel alloy butt welding structure using high-density alloy；Knife bar material selection high-density alloy, high specific gravity are closed
Golden intensity is high, and thermal conductivity factor is big, and thermal coefficient of expansion is small, has good welding performance and machinability；Cutter head material selection closes
Jin Gang.Butt weld is V-shaped, increases bonding area.High-density alloy knife bar effectively increases boring cutter compared with steel knife bar
Bar rigidity, suppresses bending and vibration, resistance to knife ability of shaking increases substantially, especially in the big processing environment of draw ratio, after processing
Dimensional accuracy improves, and surface roughness reduces.Inflatable mouth is set on transition face, and in machining, iron filings have the knife of boring blade
Point is splashed to the hole wall on opposite, and because the air blowing of inflatable mouth acts on, during scrap iron from splashing, the speed of its radial direction is cancelled,
Iron filings fly out axially outward along hole.The scuffing of the hole wall avoided, improves crudy.
