Abstract
The invention relates to a bending machine for the production of bent profile sections, in particular for exchanger tubes, including a frame on which an articulated arm is mounted consisting of a rotatably fixed arm capable moving along a transverse axis of movement, and a rotary arm supported by a rotary shaft and having a means for attaching a clamping jaw, a means for mounting either a freely rotating roller or a clamping shape rotatably secured about said rotary shaft on the rotary shaft of the articulated arm, driving rollers distributed in two series and positioned on either side of a bending axis, and a means for actuating said driving rollers for synchronously rotating the latter.
Claims20
A bending machine for the production of bent profile sections, the bending machine comprising:
- a frame;
- a means for holding the profile sections along a longitudinal axis of movement, wherein the means for holding is mounted on the frame;
- a bending means for bending said profile sections, wherein
- the bending means is mounted on the frame,
- the bending means include an articulated arm,
- the articulated arm includes a rotatably fixed arm and a rotary arm,
- the rotary arm is articulated with respect to said rotatably fixed arm about a rotary shaft extending along an axis of rotation orthogonal to the axis of movement,
- the rotatably fixed arm is mounted on the frame via a means for moving the articulated arm along an axis of transverse movement perpendicular to the plane, and
- the means for moving is adapted to adjust the position of the axis of rotation relative to that of the longitudinal axis;
- and
- a means for attaching a clamping jaw carried by a means for translational movement of said clamping jaw relative to the axis of rotation, along an axis perpendicular to said axis of rotation, between a position nearer to the axis of rotation, and in a position further away from the axis of rotation;
- a means for rotatably driving the rotary shaft of the articulated arm about the axis of rotation;
- a means for mounting on the rotary shaft of the articulated arm either a roller freely rotatable relative to said rotary shaft or a clamping form rotatably fixed relative to said rotary shaft;
- a means for translationally entraining and guiding a profile section of said profile sections along the longitudinal axis, wherein said means for translationally entraining and guiding includes driving rollers;
- a means of mounting the driving rollers is adapted to distribute the driving rollers into two series positioned on either side of the longitudinal axis,
- a means for translationally moving one of said series of driving rollers along an axis perpendicular to the longitudinal axis, between a position for clamping and entraining a profile to be bent between the two series of driving rollers, and in a position for introducing a profile to be bent between said series of driving rollers;
- and
- a means for actuating the driving rollers adapted to rotatably actuate the driving rollers synchronously in the driving rollers position for clamping and entraining a profile to be bent.
