MACHINE AND METHOD TO CHEMICALLY ENGRAVE A PLATE OF STAINLESS STEEL

摘要

A chemical engraving machine to engrave a plate of stainless steel moved along an horizontal direction, said machine comprising a base, an acid liquid circuit adapted to chemically attack said plate of stainless steel at locations where it is not protected by a protection mask, a lower guiding device, an upper guiding device, the lower and upper guiding devices being configured to maintain said plate of stainless steel substantially vertically, and a nozzle support bearing a plurality of spraying nozzles projecting horizontally the acid liquid toward the plate of stainless steel. A method chemically engraves a plate of stainless steel in a vertical position.

主权项

1. A chemical engraving machine to engrave a plate of stainless steel configured to be moved along a first direction, said machine comprising:
a base, a housing, an acid liquid circuit adapted to chemically attack said plate of stainless steel with an acid liquid at locations where the plate is not protected by a protection mask, a lower guiding device borne by said base, an upper guiding device located above and substantially vertically with regard to the lower guiding device, the lower and upper guiding devices being configured to maintain said plate of stainless steel substantially vertically, and at least a nozzle support bearing a plurality of spraying nozzles configured to project the acid liquid toward the plate of stainless steel substantially horizontally.
