Bending machine for the production of bent profile sections, in particular for exchanger tubes

摘要

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.

主权项

1. 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.
