Abstract
The utility model discloses a cutting instrument, including the cutting instrument main part, the cutting instrument main part includes tool bit body and knife rest, the knife rest is connected with the tool bit body through the connector, be provided with the heliciform cutting edge on the tool bit body, the tool bit body is inside to be equipped with the curve oil groove and to run through the knife rest, the inside coolant channel that still is equipped with of tool bit body, coolant channel follows the heliciform cutting edge upper shed of tool bit body bottom upwards extends to the knife rest top is connected with the emollient accumulator that sets up at the knife rest top the outside of connector, still detachably is equipped with the annular from the wind ring of cooling down, the annular is equipped with a plurality of wind holes around the wind ring of cooling down, it gathers the aerofoil still to be equipped with outside every wind hole. The utility model discloses a three kinds of cooling method combine together, and it is effectual to cool down, and lubricated effect is splendid for the tool bit body obtains furthest's protection, has prolonged cutting instrument's life greatly, and does not need the extra power, is worth promoting.
Description
Technical field
The utility model relates to a kind of cutter.
Background technology
Common cutter is when holing, and because friction causes cutter hub itself and blade overheated, cutter hub itself is distortion easily, blade easily weares and teares, if directly sprayed water in outside, can reduce frictional force, and easily skid, people need to find better solution.
Utility model content
For solving the problem, the utility model discloses a kind of cooling and high lubricating effect, long service life cutter.
For realizing this purpose, the structure that the utility model adopts is:
A kind of cutter, comprise cutter body, cutter body comprises bit body and knife rest, described knife rest is connected with bit body by connector, described bit body is provided with helical form blade, described bit body inside is provided with curved oil groove and runs through knife rest, described curved oil groove is walked around blade, enter from a terminal knife edge, other end blade goes out, described bit body inside is also provided with coolant channel, described coolant channel is from the helical form blade upper shed bottom described bit body, extend upwardly to described knife rest top and be connected with the lubricant reservoir being arranged on knife rest top, in the outside of described connector, also removably be provided with annular from lowering the temperature vane, described annular is provided with some air holes around cooling vane, described each air holes is also provided with wind gathering plate outward.
As preferably, a cavity is provided with in the middle of described connector, cavity centre is provided with a passage corresponding with coolant channel, and cavity is divided into two by two pieces of dividing plates by the outside of passage, and described two cavity bottom of separating are equipped with the through hole corresponding with curved oil groove.
Its beneficial effect is: the utility model; inner curve oil groove and coolant channel is adopted to coordinate cooling cutter hub and blade; adopt outside annular to carry out wind-guiding cooling from cooling vane in outside, three kinds of types of cooling combine, good cooling effect; lubricant effect is splendid; bit body is protected to greatest extent, substantially prolongs cutting-tool's used life, and do not need extra power; economize on resources, be worthy to be popularized.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of connector;
Fig. 3 is the schematic perspective view of annular from cooling vane;
