Definitions

  • the present invention relates to a machine for bending metal wires.
  • the present invention relates to a machine for making bends without requiring pivoting of the wire.
  • This inexpensive machine reduces industrialization times. It facilitates the development by the limited number of shaping tools. It allows easy monitoring of any changes to the workpieces. Because the wire is always held during the shaping, the quality of the parts obtained is good. The machine allows close bends and easy adjustments without moving the actuators.
  • the machine according to the invention is characterized in that it comprises bending units each equipped with a rotary head for bending the wire rotating around an axis orthogonal to the axis of supply of the wire.
  • the cambering unit comprises a rotary cylindrical spindle provided with two pins and ensuring, by rotation, the folding of the wire engaged between the pins and means for moving said spindle in translation so as to ensure the disengagement of the wire after folding of it.
  • the cambering unit comprises a motor for rotating the spindle which is mounted on the fixed parts and is connected to the spindle by means of a constant velocity connection.
  • the bending unit is mounted on support means allowing its orientation around the wire supply axis.
  • the machine comprises a flat frame 1 (table or marble) carried by a frame, not shown.
  • This chassis can be tilted.
  • the wires to be bent 5 supply the machine along a supply axis marked 51.
  • the supply can be manual. In this case, the operator positions a straight and cut yarn blank.
  • Power can be supplied by an automatic device.
  • a first type of automatic feeding device can be constituted by a charger containing the precut blanks.
  • Another type of automatic device can ensure the straightening, running and cutting of a wire from a spool.
  • the chassis carries a linear camber unit 2, a first rotary camber unit 3 and a second rotary camber unit 4.
  • the linear bending unit 2 consists of a support 21 provided with slides 22 used to guide a movable slide 23 along an axis 24.
  • the slide carries at the front end a forming tool 25 having a curved profile suitable for bending longed for.
  • This movable slide cooperates with a fixed anvil 26 equipped with a forming tool 27 having a curved profile conjugated with the profile of the slide.
  • the movable slide 23 is driven in an alternating rectilinear movement by a linear actuator 28, of the jack type, fixed on the support 21.
  • the entire unit 2 can be moved horizontally on the chassis 1.
  • the axis 24 is perpendicular to the axis 51.
  • the unit can be tilted without the plane of the chassis 1 relative to the axis of wire feed 51.
  • Each rotary unit 3 or 4 comprises a housing 31 or 41 ensuring the guiding in rotation and translation of a cylindrical spindle 32 or 42 constituting a rotary head for bending the wire.
  • This pin has a central pin 33 or 43 and an eccentric drive pin 34 or 44. By rotation of the pin around the axis 35 or 45, this head makes it possible to produce a fold on the wire at an angle of 0 to 270 °.
  • the spindle 32 or 43 can be moved in translation along 35 or 45 by a linear actuator 36 or 46 fixed to the housing 31 or 41.
  • the spindle 32 or 42 is driven in rotation by a rotary actuator 37 or 47 mounted on the fixed parts of the machine.
  • the housing 31 or 41 is mounted on an orientable support cradle 39 or 49 so as to be orientable around the feed axis 51 of the wire.
  • the actuator is connected to the spindle via a constant velocity connection with cardan joints 38 or 48. This connection allows adjustments in position of the rotary units.
  • Each unit 3 or 4 can be moved along axis 51.
  • the bending unit 2 folds the wire 5 in a plane. It maintains the wire during the bending carried out by the rotary units 3 and 4.
  • the rotary units 3 and 4 are then actuated in an order determined by the final shape of the part.
