Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figs 1-4, cold drilling cutters in a kind of accurate automobile die copper sheathing cooperation hole machined Special central, including knife
Handle 1 and cutter hub 2, the fixing groove 1a that knife handle 1 is equipped with recess knife handle 1 are set on the knife handle 1 for being attached with equipment
There is a coolant liquid conveyor chamber 3, which extends through the end of cutter hub 2 to 2 direction of cutter hub, and coolant liquid can
It inputs from knife handle 1, is exported from 2 end of cutter hub, the cutter hub 2 is equipped with a chip space 4 being axially arranged along cutter hub 2.
In mold cylinder set matching hole process, cutting can generate a large amount of copper scale, since copper has preferable extend
Property it is not easy to break, such as chip removal not in time, to further drilling processing will cause obstruction, it is serious to will cause Drill Crack, this reality
The chip space 4 applied in example is axially arranged along cutter hub, provides the channel for directly going out bits, in process, copper scale can be whole
Quick chip removal is realized in the quick discharge of item, guarantees the lasting progress of drilling work.
Coolant liquid can be added from coolant liquid conveyor chamber 3,2 end of cutter hub of going directly, after the discharge of 2 end of cutter hub, to cutter hub
The contact position of end and workpiece is cooled down and is lubricated, and the temperature in process is reduced, avoid temperature excessively high to workpiece and
Cutter hub damages.Coolant liquid can be water, be also possible to lubricating oil.
Specifically, chip space 4 axially extends to 1 bottom of knife handle along cutter hub 2, and 2 bottom of cutter hub, which is equipped with, bores milling knot
Structure 5 bores main component of the milling structure 5 as cutter hub, directly acts on workpiece, process to workpiece.
Boring milling structure can be used the structure of circular knife, and in the present embodiment, boring milling structure 5 includes protruding from 2 end of cutter hub
Parting line 6,2 end of cutter hub is divided into two brill milling faces 7 by the parting line 6, the setting in two brill milling faces 7, cutter hub 2 just
Turn or reversion process in, have brills a milling face that can directly contact with workpiece, to improve the efficiency bored and mill operation, coolant liquid is defeated
Send the brill milling face 7 therethrough of chamber 3, coolant liquid can be exported directly from boring milling face 7, and go directly working position, to working position into
Row cooling.In the present embodiment, boring milling face 7 is in form knife to the cabochon of lower recess namely each both ends for boring milling face 7
Sword.
In conjunction with shown in Figures 5 and 6, boring milling structure 5 further includes the reaming body 8 to extend radially outwardly along cutter hub, the reaming
