Patent ID: 7743911

Claim:
A drawing machine for drawing a linear workpiece ( 10 ) through a drawing die, the drawing machine comprising: a caterpillar conveyor ( 1 ) comprising a first chain carrier ( 2 ), a second chain carrier ( 3 ), a first tool chain ( 6 ) and a second tool chain ( 9 ), wherein said first chain carrier ( 2 ), said second chain carrier ( 3 ), said first tool chain ( 6 ) and said second tool chain ( 9 ) are disposed in and form a drawing plane ( 19 ) in which the workpiece to be drawn is caused to move; a frame ( 15 ) supporting said caterpillar conveyor ( 1 ), wherein at least one of said first chain carrier ( 2 ) and said second chain carrier ( 3 ) is displaceable relative to said frame ( 15 ) via a pressure cylinder ( 14 ) rigidly coupled to said frame ( 15 ); said frame ( 15 ) comprising a first frame half ( 16 ) disposed on a first side ( 18 ) of the drawing plane ( 19 ) and a second frame half ( 17 ) disposed on a second side ( 20 ) of the drawing plane ( 19 ), wherein said first frame half ( 16 ) is substantially identical to said second frame half ( 17 ) such that said frame ( 15 ) comprises a substantially symmetrical structure with respect to the drawing plane ( 19 ); said first frame half ( 16 ) comprising a first main beam ( 23 ) and said second frame half ( 17 ) comprising a second main beam ( 24 ); wherein each of said first main beam ( 23 ) and said second main beam ( 24 ) is subjected to a substantially equal tensile load ( 27 , 28 ) in a respective tensile region ( 30 ) when press-on forces are applied to the workpiece ( 10 ), thereby providing for a substantially equal distribution of the press-on forces ( 13 ) which are absorbed by the frame ( 15 ).
