Description
Technical field
This utility model relates to Grinding Technology field, is specifically related to the wheel grinding system of a kind of electrostatic spraying lubricant coating.
Background technology
Grinding is the important processing technique of polish, its course of processing is to use emery wheel to interact with workpiece, owing to wheel face abrasive particle is usually negative rake cutting, therefore the heat produced in Grinding Process is much larger than other form processings, in the grinding of grinding especially difficult-to-machine material, the mechanical energy consumed is largely converted into heat energy and accumulates in grinding arc area, and major part has the feature of poor thermal conductivity in difficult-to-machine material, if can not in time the heat that grinding process produces be evacuated away, may result in grinding arc area temperature drastically to raise, emery wheel is caused to scrap, workpiece surface to be machined grinding such as is burnt at hot injury's phenomenon.
In traditional grinding, in order to cool down the high temperature of grinding arc area in time, the general grinding fluid using flowing continuously washes away grinding arc area, takes away heat by the grinding fluid of flowing, but in order to ensure radiating efficiency, generally requires the substantial amounts of grinding fluid of use.A large amount of uses of grinding fluid not only increase production cost and also can work the mischief ecological environment and the healthy of operator, and the airflow barrier that emery wheel high speed rotating is formed makes grinding fluid be difficult to effectively enter grinding arc area, the requirement being actually needed but also running counter to green processing of cooling in grinding the most not only cannot be met.
For these reasons, seek novel not only improving and reduce the method that grinding arc area temperature is the most economic and environment-friendly, all have highly important meaning for reducing the hot injury of difficult-to-machine material surface of the work and the protection of ecological environment in grinding process.
Utility model content

This utility model is achieved by following technical solution:
The wheel grinding system of a kind of electrostatic spraying lubricant coating, this system includes workbench, and workbench is connected with the fixture of clamping workpiece, workbench earth lead, and workpiece contacts with emery wheel, and emery wheel is driven by grinding wheel spindle；Also including and emery wheel interval is arranged and servo-actuated spray gun, spray gun bottom is provided with handle, and handle end is provided with shower nozzle equipped with duff pipe, spray gun front end, is fitted with electrode needle in the middle part of shower nozzle, and spray gun is also equipped with binding post and compressed air hose.
Distance between electrode needle end and the emery wheel of described spray gun front end is 1-5cm.
Angle between described spray gun axis and surface of the work is 4-10 °.
The pressure of described compressed air hose is 10-15MPa.
The beneficial effects of the utility model are:
Compared with prior art, the wheel grinding system of the electrostatic spraying lubricant coating that this utility model provides, by electrostatic painting process, solid lubrication powder is sprayed to stone surface, solid lubricating powder directionally sprays to stone surface under the common effect of electrostatic attraction and pressure-air, one layer of homogeneous and continuous print solid lubricant coating is formed on stone surface, the rubbing action between emery wheel and workpiece is made to be converted into emery wheel and composite lubricating film, rubbing action between workpiece and composite lubricating film, so can effectively reduce the coefficient of friction of grinding skin, reduce the adhesion wear of abrasive particle, thus reduce grinding arc area temperature, improve the purpose of surface of the work crudy.And use nontoxic solid lubrication powder, it is possible not only to reduce processing cost, and ecological environment and the healthy of operator will not be worked the mischief.
