Description
Technical field
The utility model is related to cutting tool for CNC machine technical field, more particularly to a kind of split type hard alloy milling
Knife.
Background technology
Wolfram steel, is a kind of hard alloy, also referred to as tungsten-titanium alloy, and it is a series of that it has hardness high, heat-resisting, corrosion-resistant etc.
Premium properties, particularly its high rigidity and wearability, even if being also held essentially constant at a temperature of 500 DEG C, at 1000 DEG C
When still have hardness very high.Wolfram steel milling cutter is the cutter that a kind of wolfram steel makes, and is typically mainly used in numerical control machining center, CNC
Engraving machine；Wolfram steel milling cutter hardness is Vickers 10K, is only second to diamond；Wolfram steel milling cutter has the characteristic for being difficult to be worn just because of this,
And matter is crisp hard is not afraid of annealing；Therefore it can be attached on plain-milling machine and process some harder uncomplicated heat treatment materials,
It is widely used, and can be used for High-speed machining.The basic law of cutter wear is similar to lathe tool.The thickness of cutting of high-speed tungsten steel milling cutter
It is smaller, especially in upmilling, cutter tooth to workpiece surface extrude, slide more serious, so cutter wear occur mainly in behind on.
During with wolfram steel face milling cutters milling steel part, because cutting speed is high, chip is big along above sliding speed, therefore flank wear is simultaneously, before
Also there is less cutter wear.Wolfram steel face milling cutters carry out high rate intermittent cutting, cutter tooth is undergo mechanical shock and heat repeatedly
Impact, cracks and causes the endurance failure of cutter tooth.Milling Speed is higher, produces this cutter wear just more early and tighter
Weight.Most of wolfram steel face milling cutters lose cutting power because of endurance failure.If the selection of milling cutter geometric angle is unreasonable or uses
It is improper, cutter tooth intensity difference, then cutter tooth can be produced without the cutter wear of crackle after very big impulsive force is born.Accompanying drawing 4, passes
The wolfram steel milling cutter of system, it is typically integrally formed, so scrap treatment after wolfram steel cutter wear, and tungsten carbide tipped tool into
This is higher, causes entirety to be scrapped because milling cutter tip is damaged, and it causes the waste of resource, so a kind of split type wolfram steel of design
Into the demand in market, cutter head can be changed knife, and such handle of a knife can just be reused, and be conducive to cost-effective and resource weight
It is multiple to utilize.
The content of the invention
The technical scheme that the utility model is used is：A kind of split type carbide-tipped milling cutter, it is characterized in that, closed by hard
Golden holder main body, carbide bit and screw composition, the head center of hard alloy handle of a knife main body are provided with screw attachment holes, and
Two bar grooves are vertically outputed in the head of hard alloy handle of a knife main body, " well " font groove position is formed, carbide bit bottom sets
There is square protruding end, carbide bit is fixed with hard alloy handle of a knife main body by screw connection, carbide bit bottom
The center of " well " font groove position of protruding end and hard alloy handle of a knife body head inlay, realize that locking is fixed.
Screw described further is countersunk head screw, and carbide bit is squeezed into firmly with hard alloy handle of a knife main body by screw
The screw attachment holes connection of the screw hole and hard alloy handle of a knife body head at matter alloy cutter head center, and screw is absorbed in hard
In the screw hole of alloy cutter head.
Preferably, the carbide bit is provided with spiral cutting sword, the connected hard alloy handle of a knife body head of correspondence
Portion is provided with the cutting edge end mutually continued with the spiral cutting sword of carbide bit.
Preferably, the carbide bit includes the cutter head of different size model, and hard alloy handle of a knife main body is constant, can
The cutter head for changing different size model is connected with hard alloy handle of a knife main body close-fitting.
The beneficial effects of the utility model are：By the implementation of the technical program, split type wolfram steel milling cutter, handle of a knife are designed
It is split type with cutter head by screw connection, and in joint face, knife upper end is by outputing two perpendicular Cao Yu centers
Screw attachment holes periphery one " well " font groove of composition position, the centrical square groove of " well " font groove is used for and carbide bit bottom
Protruding end realize concave inlaid position, to strengthen the stationarity of cutter head and handle of a knife, when carbide-tipped milling cutter works, it is ensured that knife
Will not be misplaced between handle and cutter head and dislocated, to strengthen the stationarity of cutter head and handle of a knife.The cutter head and handle of a knife of carbide-tipped milling cutter
Split type connection, the cutter head for being on the one hand convenient for changing different size model is used, and buys a wolfram steel handle of a knife and multiple cutter heads, property
Valency saves acquisition cost than higher；On the other hand, in carbide bit by using for a long time, can be by after its abrasion
Cutter head is removed, the cutter head for more renewing, and advantageously reduces the waste of resource.
