Abstract
Welding electrodes are continuously coated with a flux material with this pressure coating system. The flux material is supplied to the coating station by two supply bins which are automatically controlled such that the flux material is always supplied to the coating station. While one supply bin is supplying the flux material to the coating station the other bin is being replenished in an alternate manner.
Claims10
A coating apparatus for continously applying a single layer of welding flux material mixture to an elongated metal core passing through a coating station comprising,
- a cast body having said coating station mounted at a top portion therein, said coating station being in communication with an annular chamber located within said cast body,
- an elongated guide member mounted in said cast body and having an elongated opening extending throughout the entire longitudinal length therein and being operative for guiding said metal core towards said coating station,
- at least two supply bins coupled to said cast body and containing the same said welding flux material mixture, and adapted to supply said welding flux material mixture from one bin at a time alternately to said coating station,
- a sliding control valve member connected to said supply bins and to said cast body, said control valve member being operative to connect said supply bins, one bin at a time, alternately and selectively to said annular chamber for supplying said welding flux material mixture to said coating station from one supply bin, while simultaneously closing communication of the second supply bin from said annular chamber.
A coating apparatus for continuously applying a single layer of welding flux material coating to a metal core to form a coated welding electrode, comprising
- a cylindrical cast body having a lower extension portion and a side extension portion, and a cylindrical inner chamber located within said cast body,
- an annualar sleeve member mounted at a top portion of said inner chamber and operative as a coating station of said metal core, said annular sleeve member having a central through opening with a diameter equal to the diameter of a coated welding electrode,
- oblique ducts formed in said side extension portion of said cast body, and a vertical through opening formed in said lower extension portion of said cast body,
- an elongated guide member mounted to said cast body and extending into said inner chamber through said vertical through opening of said lower extension portion of said cast body, said guide member having a longitudinal opening extending throughout the entire longitudinal length therein and being operative for guiding said metal core towards said central through opening of said annular member,
- two pressurizable welding flux material supply bins coupled to said cast body, and adapted to supply same said welding flux material mixture alternately, one bin at a time, to said coating station,
- a sliding control valve member disposed between said supply bins and said cast body and being operative selectively and alternately to open communication of one of said supply bins from said coating station, and simultaneously closing communication of the other one of said supply bins from said coating station.
