(57) A machine for realizing machanical radiators, particularly those for motor vehicles,
including positioning and support means for the radiators to be treated and a plurality
of rods provided with an expansion element at one end and associated with means for
their movement along the tubes of said radiators, characterized by comprising:
- a loading table (1) removably housing a radiator (2) in a blocked condition during
the expansion treatment and having the walls in contact with the ends of said tubes
(4) provided with openings facing them, for the passage of said rods (10),
- vertically mobile means (17), for holding the expansion elements (11) in the correct
reciprocal operative position,
- stationary means (16) placed between the loading table (1) and said holding means
(17) for centering and guiding said rods (10) in the correct reciprocal operative
position, and
- a device (12) for the disengageable hooking of the ends of the rods (10) not provided
with the expansion element (11) and making traction on it, said device (12) being
placed on the part of the loading table (1) opposite to that in which said stationary
centering means (16) and said mobile holding means (17) are.
