Abstract
A stretching machine for extruded profiles comprises a stretching head capable of translating along a predetermined direction (X) on a basement and actuation means for translationally actuating the stretching head with respect to the basement. The actuation means comprise a mechanical drive comprising at least one motor element, which is integral with one of said stretching head and said basement, and at least one driven element, operatively connected to the at least one motor element and integral with the other of said stretching head and said basement, and an electric motor operatively connected to the motor element of the mechanical drive.
Claims5
A stretching machine for extruded profiles comprising:
- a stretching head capable of translating along a predetermined direction (X) on a basement, actuation means for translationally actuating the stretching head with respect to the basement and for generating a required stretching force, the actuation means comprising:
- a mechanical drive comprising at least one motor element and at least one driven element, operatively connected to the at least one motor element, and an electric motor operatively connected to the motor element of the mechanical drive, with the interposition of a reduction gear, wherein the electric motor has a rotation axis perpendicular to a rotation axis of the motor element of the mechanical drive;
- and a counter-head having an adjustable position on the basement in relation to the stretching head and being kept fixed during a stretching process, wherein the stretching head and the counter-head are capable of clamping opposite longitudinal ends of said extruded profiles to be stretched and are mounted on the basement at the longitudinal ends of said extruded profiles;
- wherein the mechanical drive is a rack and pinion drive, wherein the pinion forms said at least one motor element and the rack forms said at least one driven element, and wherein the pinion is integral with the stretching head and the rack is integral with the basement;
- wherein at least a portion of the actuation means is coupled to the stretching head so as to move with the stretching head;
- wherein the at least one motor element is the portion of the actuation means coupled to the stretching head so as to move with the stretching head.
