Sheet-met′al press.
A machine for forming articles of sheet-metal by pressure. That illustrated consists of a table having two uprights B B, the upper ends of which are united by a bar A; said uprights form the guides for a beam which carries the punch F, and to which a rising and falling motion is imparted by a treadle T. The punch is secured to the beam by means of a stem, the lower end of which fits in a socket in the punch. The punch is made to correspond to the shape of the pans to be produced, and from its corners project wings a a which, when the punch is depressed, fit into corresponding slots in the corners of a die; this die is constructed of a series of sections which are made wedgeshaped, and is held in position by adjustable brackets. |
