Definitions

  • the present invention relates to an apparatus portable electric for bending tubes.
  • Such devices are for example described in documents FR 0.501.545, EP 0.536.632, EP 0.374.110, EP 0.350.457.
  • the shape is rotated by through a motorization, the bending tube, placed between the form and the counter-form, is driven by the hook and is wound on the form.
  • the engine is preferably associated with a reducer for, in addition to obtaining a maximum torque, perform bending slowly so to have a regular effort and stop it when the curvature reaches the desired angle.
  • the training hook integral with form does not allow, as designed currently, a quick and easy disengagement of the tube after its bending.
  • the object of the present invention is to provide a portable electrical device for bending tubes to overcome the various aforementioned drawbacks.
  • the portable electrical appliance for bending tubes is of the type having a shape semicircular with a peripheral section groove semi-circular and associated with a drive hook, a counter-form which, via a carriage, is moving closer to said shape and which has also a groove, said shape and said hook being able to be moved in rotation, and it is characterized essentially in that said counterform is subject said carriage by interlocking on a stud.
  • the hook is pivotally mounted in a limited way on the shape around an axis parallel to the axis of rotation of said shape.
  • the positioning of the hook is indexed on the form.
  • a portable electrical device for bending tubes comprises a body 1 provided with a handle portage 10, as well as a motor unit 2 equipped with a trigger 20 for starting.
  • the body 1 contains, in known manner, a reduction gear, not visible, capable of rotating a square 11 intended to accommodate a shape, not shown.
  • the body 1 also comprises, laterally a lever 12 of operation of a disengaging system of the drive.
  • a carriage 3 also visible in FIG. 2, is slidably mounted in the body 1 substantially in direction of square 11, its displacement being carried out by through a screw-nut system 30 operated by a handle 31.
  • the carriage 3 has at its upper part a nipple 32 intended to receive, by simple fitting, a counterform, not shown.
  • Form 4 traditionally consists of a disc part having in its curved edge a groove 40 of semi-circular section with a corresponding radius at a given tube diameter, and axially a bore 41 allowing its setting on the square there.
  • Counterform 5 consists of a shape block general parallelepiped, centrally comprising a circular bore 50 for fitting onto the nipple 32, and, in each of its lateral faces, a groove straight 51 of semi-circular section, the grooves 51 being, in known manner, of different radii.
  • the counterform 5 is simply fitted on the nipple 32, then, by the displacement of the carriage 3, the tube to be bent is held between the counter-form 5 and shape 4, being engaged in one of the grooves lateral 51 of the counterform 5 and in the groove 40 of the form 4.
  • Counter platform 5 is freely mounted in rotation around the nipple 32 but is held in position during the bending operation by the pressure of the counterform 5 against the form 4 via the tube.
  • the counterform 5 can undergo a slight rotation during the bending operation favoring a quality bending.
  • the form 4 has a drive hook 42 pivotally mounted on an axis 43 eccentric with respect to the axis of rotation of the form 4, and which can be indexed in the position of bending via an indexing means 44, the ball and spring type, incorporated in form 4.
