Abstract
A smoothing and shrinking arrangement for dented articles such as plates or the like, which arrangement includes an electrode connected to one pole of a voltage source, the other pole of which is connected to the plate being worked. A shielding element surrounds the electrode with a cooling construction being provided at the electrode for cooling at least a region of the plate affected by the electrode.
Claims29
An arrangement for smoothing and shrinking a dented article, the arrangement comprising:
- an electrode means for effecting a heating of at least a portion of the article, said electrode means including an end face for contacting the article, said electrode means and the dented article being connectable with a voltage source means;
- a cooling means provided at said electrode means for cooling at least a portion of the article affected by said electrode means, said cooling means consisting of a means for selectively impermanently taking up a cooling fluid having an outer end surface which is aligned with said end face of said electrode means;
- and
- a shield means mounted at said electrode means so as to be coaxial therewith for shielding the electrode means, said shield means including a cylindrical casing means for accommodating said cooling means, said cylindrical casing means defining an annular space between said electrode means and said casing means with said cooling means being accommodated in said annular space.
