Abstract
An electrical battery pole or terminal (50) is cold-produced by means of a process comprising axial compression at room temperature of an essentially cylindrical metal element (42) between a first and a second portion of die (1) and (2), travelling one opposite to the other, of which the first (1) forms that part which will be the protruding part (13) of the battery pole or terminal and the second (2) portion of die, by subjecting the lower part of the metal block to compression, forms the electrical battery pole's lower part, which is provided with shaped portions (35) forming a number of ribs.

An apparatus for making an electrical battery pole or terminal (50) which comprises a first operating die (1) moving vertically upwardly and downwardly and provided with a cavity (13) shaped according to the configuration of said pole or terminal (50), first drive punch (11) operating with one end (14) in said cavity (13);
- a second stationary die (2) positioned under said first die provided with a second operating punch (33) moving vertically through said die and with a cavity (32) coaxial to cavity (13) of first die (1), in lower part thereof being shaped according to said punch (33), and in upper part thereof being shaped in accordance with the shape of the lower part of pole (50).
A process for making an electrical battery pole or terminal by formation of a semi-finished product and subsequent blanking of ends, which consists of molding an essentially cylindrical, metal block (42) and compressing said block between a first die (1) and a second die (2), said first die co-operating with an operating punch (11), keeping the block (42) in a stable position, said second die cooperating with a second operating punch (33), inserting the block (42) into a cavity (13 and 35) formed between the first and the second die (1, 2) and of shape of the semi-finished product desired;
- subjecting the part of block (42) inserted into cavity (35) of second die (2), to an expansion action whereby outer, protruding ribs, essentially parallel one to the other on said end of said pole are obtained.
