Abstract
The heat pipe type superhard abrasive tool as one kind of abrasive tool includes one grinding head, one pipe union, one grinding head handle and one water jacket. The grinding head serving as the casing of heat pipe has one conic hole as the work cavity of the heat pipe and possesses high heat transferring efficiency. The abrasive tool adopts diamond or CBN with very high heat conducting capacity as the abrasive material has reduced heat resistance between the grinding arc area and the wall of the heat pipe. The cold end of the heat pipe is cooled with the water jacket, so that the work fluid may be liquefied fast, and this is favorable to grinding refractory material with high heat flow density. Adopting heat pipe as the heat conducting element can dissipate heat directly, avoid the heat damage of the superhard abrasive tool and the refractory material, and omit grinding fluid for protecting environment.
Description
Technical field
The present invention relates to a kind of heat pipe type superhard abrasive material grinding tool, be specially adapted to use the sintered carbide tools of high temperature brazing super hard abrasive (as diamond, CBN) carries out grinding to difficult-to-machine material manufacture field.
Background technology
In the grinding of grinding especially difficult-to-machine material, the heat major part that is consumed accumulates in grinding arc area with the form of heat energy, and difficult-to-machine material itself has the characteristics of poor thermal conductivity, if can not in time these heats be dredged away, to cause the grinding arc area temperature sharply to raise, and cause very soon super hard abrasive instrument or part burn, scrap.For reaching timely cooling purpose, usually use cooling fluid that the arc district is cooled off in the grinding process, but the cooling fluid that can enter into grinding arc area and really play the heat exchange effect only accounts for very small scale, so not only can't satisfy in the grinding cooling requirement but also run counter to requirements of green environmental protection.Therefore, design and develop and efficiently to dredge the instrument of grinding arc area heat and environmental protection, have crucial meaning.
Summary of the invention
The purpose of this invention is to provide that a kind of heat exchange efficiency is high and simple in structure, the heat pipe type superhard abrasive material bistrique of environmental protection, be specially adapted to use the sintered carbide tools of high temperature brazing super hard abrasive (as diamond, CBN) carries out grinding to difficult-to-machine material manufacture field.
The present invention applies to the heat pipe cooling technology in the grinding, the center of gravity of cooling turns to grinding tool by workpiece, utilize heat pipe and super hard abrasive (diamond, CBN) You Yi heat conductivility, the heat that produces in the grinding arc area is conducted rapidly by heat pipe, grinding temperature when processing the material grinding material to reduce difficulty, can not only satisfy the requirement of high efficient heat exchanging, can also reach the purpose of low energy consumption, guarantee that tool surfaces super hard abrasive and difficult-to-machine material workpiece are not subjected to fire damage in the difficult-to-machine material grinding, not only improve the service life of superhard abrasive material grinding tool, and improved the machined material surface quality.
The present invention is achieved in that processing one blind hole in the bistrique matrix, as the rotating heat pipe working chamber, it is characterized in that this hole has the tapering of 2～5 degree, and the aperture is increased to the hot junction gradually by cold junction.
Because heat flow density is very big during the difficult-to-machine material grinding, it is not enough only relying on the heat pipe cold junction to cool off voluntarily, therefore adds a water jacket as cooling device at the bistrique cold junction.
Heat pipe type superhard abrasive material grinding tool of the present invention comprises bistrique, pipe joint, bistrique handle, water jacket.Described bistrique has an interior blind hole with tapering, the aperture is increased to the hot junction gradually by cold junction, described bistrique handle has the central through hole that is used for extracting vacuum, the interior blind hole openend of bistrique closely links to each other with the bistrique handle by sealing ring, on the outer wall of bistrique, water jacket two outer ends connect a pipe joint respectively to described water jacket by ring set.
The tapering of the interior blind hole of described bistrique is 2～5 degree.
Grinding materials and grinding tool of the present invention, simple in structure, be applicable to that high temperature brazing super hard abrasive instrument carries out the manufacture field of grinding to difficult-to-machine material.
Description of drawings
Fig. 1 is the heat pipe type superhard abrasive material grinding tool structural representation, wherein:
1, bistrique, 2, pipe joint, 3, sealing ring, 4, the bistrique handle, 5, sealing ring, 6, water jacket
The specific embodiment
Below in conjunction with accompanying drawing, introduce content of the present invention in detail.
Fig. 1 is a superhard abrasive material grinding tool structural representation of the present invention, and the grinding tool structure is made up of bistrique 1 and bistrique handle 4, and cooling device is made of pipe joint 2, sealing ring 3, sealing ring 5 and water jacket 6.When assembling, can earlier sealing ring 3 be installed on the bistrique 1, then sealing ring 5 is installed on the bistrique handle 4, then screw in bistrique handle 4 in the bistriques 1 and compress, then the working chamber extracting vacuum in the bistrique 1 is also sealed, will be installed on the bistrique 1 by the water cooling plant that pipe joint 2 and water jacket 6 constitute at last by the hole on the bistrique handle 4.During grinding, the heat that grinding produces is transmitted to bistrique by the hot junction, cause the working medium boiling in the hot junction, the working medium of boiling rises to cold junction, under the effect of recirculated cooling water, liquefy and emit heat, the working medium of condensation is under action of centrifugal force, tube wall along tapering is got back to the hot junction, finishes a working cycles.
In the bistrique matrix, directly processed taper hole, and with bistrique itself as heat pipe package, avoided the thermal resistance between bistrique matrix and the thermotube wall, improved heat transfer efficiency.Adopt diamond or CBN as abrasive material, abrasive material itself has the high capacity of heat transmission, has reduced the thermal resistance between grinding arc area and thermotube wall.Heat flow density is big when considering the difficult-to-machine material grinding, and the heat pipe cold junction adopts water jacket 6 to cool off, and guarantees that working solution liquefies rapidly.Owing to adopt heat pipe as heat transfer element, can directly dredge the heat that grinding arc area is gathered, effectively avoid the fire damage of super hard abrasive instrument and difficult-to-machine material surface of the work, and do not used grinding fluid, environmental protection.
