Abstract

Hydraulic punching machine, essentially characterized in that it is constituted by an elongated base body of U-shaped section, with its wings arranged horizontally, whose central hollow serves as support for the accommodation of the metal elements to be drilled by arranging the front and one side of said body b references for the correct positioning of the same, being located on the upper wing a hydraulic cylinder whose piston carries in the lower end a punch that crosses an orifice of said wing until access to the central bone and lodge in another blind orifice of the other wing, whose piston has an upper portion of suitable diameter that receives the fluid under pressure from a pump, through an upper orifice, and a lower portion of smaller diameter, at the end of which the punch is joined, which constitutes an internal chamber in the cylinder in contact with an internal chamber in the cylinder in contact with a side duct l through which pressurized fluid is introduced that impinges on the annular portion of separation of the two portions of the plunger, determining the upper and lower entries of fluid under pressure, the lowering or raising of the punch and consequently the perforation of the metallic element arranged in the hollow of the base.
