Abstract
The utility model provides graphite die coating processing equipment which comprises at least one vacuum furnace, wherein each vacuum furnace is connected with a vacuum pump for pumping vacuum, an oxygen cylinder for transporting oxygen into the vacuum furnace and a propane gas cylinder for transporting propane gas into the vacuum furnace; and a copper bar for heating gas and a graphite die in the furnace is arranged in each vacuum furnace and is connected with a rectifier cabinet through a conducting wire. According to the graphite die coating processing equipment, the graphite die is placed in each vacuum furnace, a layer of pyrolytic carbon oxidation resistant film is formed on the surface of the die under the action of oxygen and propane gas, so that the defect of oxidation resistance failure of a graphite material is overcome effectively, and the service life of the graphite die can be prolonged by 4-5 times.
Description
Technical field
The utility model relates to machining graphite field, relates in particular to a kind of graphite jig coating processing units.
Background technology
Graphite jig in use, due to the performance of graphite material itself, be very easy to produce oxidation, affect work-ing life, if and can be at surface working one deck oxidation-resistant film of graphite jig, can make the life-span of graphite jig be extended, still, there is no at present ripe equipment for manufacturing coating to graphite jig.
Utility model content
The purpose of this utility model is to solve the defect that above-mentioned prior art exists, and providing a kind of can have the prolongation graphite jig graphite jig coating processing units in work-ing life.
A kind of graphite jig coating processing units, comprises at least one vacuum oven, and described vacuum oven is connected with vacuum pump for vacuumizing, for the oxygen cylinder to delivering oxygen in vacuum oven with for the propane cylinder to vacuum oven delivering propane gas; In each vacuum oven, be provided with the copper bar for heating furnace gas and graphite jig, described copper bar is connected with rectifier cabinet by wire.
Further, graphite jig coating processing units as above, described vacuum pump is connected with main pipeline, is communicated with subtube corresponding to some and each vacuum oven on described main pipeline, and each subtube is corresponding to be respectively communicated with each vacuum oven.
Further, graphite jig coating processing units as above is respectively arranged with air valve on each subtube.
Further, graphite jig coating processing units as above, is provided with a weather gage on each vacuum oven.
The graphite jig coating processing units that the utility model provides, by graphite jig is placed in vacuum oven, under the effect of oxygen and propane gas, form one deck RESEARCH OF PYROCARBON oxidation-resistant film at die surface, effectively solve the not oxidation resistant defect of graphite material, can make increase 4-5 doubly the work-ing life of graphite jig.
Brief description of the drawings
Fig. 1 is the utility model graphite jig coating processing units structural representation.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in the utility model, technical scheme in the utility model is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
