System and method for producingbattery terminals

Apparatus for the manufacture of battery terminals from a metallic preform, comprising:

• a support structure
• a fixed die, joined to the support structure, having a cavity for receiving the metallic preform;
• a moveable die structure, for pressing the metallic preform against the fixed die, said movable structure comprising:
• a press plate having an open housing;
• a die structure comprising at least two die portions that can be opened or closed, said die structure able to move closer or farther with respect to the press plate, said die structure:
• when closed, forming a cavity opened by its upper and lower portion having one or more walls forming the shape of a piece to be formed and being able to enter in the open housing of the press plate when pressed against the fixed die, in such way that the cavity of the fixed die is aligned with the cavity formed when the die structure is closed and in such way that the metallic preform enters said cavity when the closed die structure is pressed against the fixed die thus entering the open housing of the press plate;
• returning to an open state when it exits the open housing of the press plate after it was pressed against said press plate in order to liberate a partially formed piece;
• and
• punching means joined to the support structure, said punching means pushed through the open housing of the press plate and entering the cavity formed when the die structure is closed in such way that it presses the metallic preform against the one or more walls of said cavity and against the cavity of the fixed die, thus forming a hollow metallic piece having a lower wall.
