Description
Technical field
The present invention, which relates to, belongs to technical field of mechanical processing, and in particular to a kind of overall car of conduction cooling for dry cutting
Knife.
Background technology
Mach lathe tool is generally divided into two kinds, one kind for mechanically-clamped turning tool, that is, blade with knife body is separately positioned is easy to blade
Replacement, another kind is welded on knife body in order to which fixing blade is to ensure machining accuracy for overall lathe tool, that is, blade.
During machining, cutting fluid has the function of cooling, lubrication, cleaning, chip removal and antirust etc., but has
A little materials are because the particularity of material cannot add cutting fluid, it is necessary to carry out dry machining technology, such as carbon fibre material.Into
The problem of inevitable during row dry cutting is exactly that the temperature of turning cutting tool rises and causes the mechanical properties decrease of cutter,
Lathe tool will Fast Wearing, influence smoothly completing for turnery processing.
Cutter inner cooling but technology can be used in order to reduce the cutting temperature of lathe tool during DRY CUTTING, makes coolant in car
Circulation inside knife, heat caused by lathe tool turning is taken away by circulation fluid, so as to reduce cutting temperature, that improves cutter uses the longevity
Life and processing quality.As Chinese patent CN205414443U discloses cooling turning tool in a kind of separate type, including：Blade, blade
Seat, circular seal ring and special-shaped seal ring.It is rectangle or U-shaped that the opposite face of the blade and blade bearing, which is equipped with cross section,
Inner cycle channel, blade bearing are equipped with inlet and liquid outlet.
Existing interior cooling technology needs to open up pipeline in lathe tool, and the ruler of lathe tool is limited by when lathe tool size is smaller
Very little, it is limited to open up length and the caliber of cooling line, heat dissipation effect unobvious, and pipeline processed complex, pipe are opened up in lathe tool
The difficult easily leakage, and reduce the integral strength of lathe tool of road sealing.
The content of the invention
In view of above-mentioned problems of the prior art, the present invention provides a kind of overall car of conduction cooling for dry cutting
Knife, heat conducting bar is set in knife body, and without opening up pipeline in lathe tool, heat caused by lathe tool cutting is conducted by blade

The clamping of cutter, the right side of general turning cutter body is clamping position.
Heat caused by blade cut with blade by being transmitted in heat conducting bar, since the thermal conductivity factor of heat conducting bar is more than
The thermal conductivity factor of turning cutter body, cutting the heat overwhelming majority of generation can be conducted effectively in heat conducting bar, then be led by being welded on
The heat sink of hot rod afterbody distributes.Coolant is continuously passed through in water tank, coolant is directly contacted with heat conducting bar and heat sink, and
When effectively the heat in heat conducting bar is taken away, so as to quickly reduce cutting temperature.
For more rapid conduction heat, the thermal conductivity factor of preferably described heat conducting bar is the thermal conductivity factor of turning cutter body
More than 3 times.Further, preferably described heat conducting bar is made of beryllium copper.Beryllium copper is that mechanics, physics, chemical synthesis are functional
A kind of alloy, there is very high thermal conductivity and intensity, hardness, the heat conducting bar conduction efficiency made of beryllium copper is high and does not reduce car
The intensity of knife.
Further, the heat sink is made of copper.The good heat conductivity of copper, can efficiently conduct and distribute heat.
In order to increase the intensity of heat transfer area and as far as possible small attenuating lathe tool, further, the head of the heat conducting bar
Front end is equipped with the mounting surface being adapted with blade side, and the mounting surface is welded with blade side.
Further, the water tank open at one end, the edge seal of open end are fixedly connected on the side of turning cutter body.Adopt
With such design heat in compact overall structure of the present invention and heat conducting bar can quickly be taken away by coolant.
For increasing heat radiation area, further, if the heat sink includes one piece of bottom plate and is vertical on bottom plate
