Milling cutter, for Milling Process, has the rotary cutter of one or more blade, is mainly used on milling machine processing
Plane, step, groove, profiled surface and cut-out workpiece etc..Existing fish-tail cutter is the same with a lot of other milling cutters, at a high speed
Under rotary work state, cutting temperature raises, if reducing temperature not in time, then can be substantially reduced the milling cutter life-span.Additionally, local temperature
Degree rising can aggravate the viscous bits phenomenon of milling cutter, reduces the quality of workpiece.
Summary of the invention
The technical problem to be solved is temperature rising, weak heat-dissipating in milling cutter working angles, it is therefore intended that provide
A kind of fish-tail cutter, solves the cooling problem in milling cutter work process.
The present invention is achieved through the following technical solutions:
A kind of fish-tail cutter, the cutter head including handle of a knife, being arranged on handle of a knife front end and the cutter hub being arranged on cutter head, described cutter hub
Being made up of cutter hub main body and the blade that is positioned in cutter hub main body, the coolant that axially offers therein along described handle of a knife is led to
Road, described cooling passage extends to the junction of handle of a knife and cutter head, is provided with at least one split channel in cutter head, and shunting is logical
Road connects with cooling passage, cold hole in cutter head outer wall is additionally provided with at least one, interior cold hole and split channel one_to_one corresponding
Connection.Coolant, under the duty of high speed rotating, is delivered to cooling passage by fish-tail cutter, and coolant arrives handle of a knife
Shunting with behind cutter head junction, enter split channel, finally flow out from interior cold hole, the coolant after outflow is in action of gravity
Under flow to cutter hub, reach cooling purpose.
Described handle of a knife and cutter head are cylindric, successively decrease in the direction that the external diameter of cutter head is pointed to cutter hub along its axis by handle of a knife,
Be conducive to accelerating the flow velocity of coolant.
Described interior cold hole is uniformly distributed along the circumference of cutter head so that coolant the most uniformly flows to cutter hub, real
Existing uniform decrease in temperature.
Described blade is at least 2, in order to form the cutter hub of swallow-tail form, for milling dovetail groove.
Being provided with chip area between two adjacent described blades, chip area produces in cleaning milling process in time
Chip, it is to avoid chip pile up, hinder processing.
Described handle of a knife and cutter head are forged into one.Handle of a knife and the cutter head of conventional fish-tail cutter are connected by screw, at height
Under the duty that speed rotates, handle of a knife and cutter head easily uncoupling.If handle of a knife and cutter head being linked into an integrated entity by forging, be conducive to
Cooling passage is connected with split channel, and does not worries handle of a knife and the problem of cutter head uncoupling.
Described cutter hub and cutter head are by being welded to connect.Welding operation is simple, low cost, weldquality are good, the intensity of joint
High to be connected firmly.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, one fish-tail cutter of the present invention, has been set gradually the cooling passage that is interconnected, shunting logical by handle of a knife to cutter head
Road, interior cold hole, have the effect of internal refrigeration storage, it is possible to resolve the cooling problem in fish-tail cutter work process；
2, one fish-tail cutter of the present invention, interior cold hole is uniformly distributed so that coolant is the most equal along the circumference of cutter head
Uniform flow, to cutter hub, reaches the effect of uniform decrease in temperature.
