Abstract: The invention relates to a bending machine (M) for bending a workpiece (300), remarkable in that a clamping jaw (511) is supported by a clamping jaw holder (510) receiving at least two clamping jaws (511, 512) arranged back to back, the clamping jaw holder (510) being fastened to a shelf (513) guided and driven in translation on the bending arm (500), the support shelves (600) punctually receiving the clamping jaw holder (510) separated from the shelf (513) and to move it on either side of the bending axis transversely to the advance axis of the workpiece (300) to be bent, independently of the bending arm (500) so that the clamping jaw holder (510) can be fastened again to the shelf (513) once the bending arm (500) has been rotated 180 degrees. The invention also relates to a bending process.

Abstract: The method for producing at least one notch in an outer wall of a tube includes guiding a first punch being made of a preforming tooth, causing the preforming tooth to penetrate through the wall of the tube until a protuberance is formed, positioning a solid cylindrical mandrel inside the tube. Then, the method includes guiding a second punch with a punching tooth, a leading end of the punching tooth having a shape complementary to a shape of the notch to be made in the wall of the tube, positioning a punching mandrel inside the tube, and having a groove suitable for containing the upset material. The invention can be used for notching headrests for the seats of a motor vehicle.

Abstract: The machine for cambering, shaping, bending or curving a bar along a bending axis includes an arm, a bending shank supported by the arm, a bending head including a bending lug that is rotatable relative to the bending axis, and a feeding station for moving the bar along an axis of travel and across the bending shank. The bending head also includes: a first connecting rod supporting the bending lug and having a head, a second connecting rod having a head, the heads being coupled so as to rotate relative to a hinge axis perpendicular to the axis of travel, a first driver for translating a leg of the first connecting rod along an axis parallel to the axis of travel, and a second driver for translating a leg the second connecting rod along an axis parallel to the axis of travel.

Abstract: The invention concerns a machine for cambering, forming, folding or bending a bar, a wire or an extruded shape. The invention includes a bending form provided with a clamping system, a device for orienting the tube, and a bending jaw (8). The bending jaw is prismatic and machined to the tube radius on at least one of its surfaces. The kinematics of the displacement of the bending jaw in a peripheral area at the bending form is provided by any combination of at least two, rectilinear or rotating, movements. The bending jaw is steerable in rotation about a median axis perpendicular to the bending plane. The bending jaw is mobile in the vertical direction to provide multiple bending operations.

Abstract: The invention relates to a bending head, for example, for a rotary draw bending technique, of the type including a bend form clamp assembly set in rotation about an axis and at least one roller keeping a tube or a profiled section clamped against the bend form during bending. The single assembly can be positioned in one or other of two bending starting positions that are symmetric with respect to the axis of the tube so as to allow either bending in one direction of bending starting from, or bending in an opposite direction starting from (P2). The rectilinear movement of the clamp in two directions (ox) and (oy) and its optimal orientation relative to the roller are obtained using a system involving an eccentric.

Abstract: The invention concerns a machine for automatically shaping components via different types of bending provided in a common plane or different planes. The machine includes a first device for performing a sequential shaping with standard tools by individual bending, and a second device using a tool plate. Both devices are managed by a single digital control. The method for controlling such a machine is characterized in that digital control provides the possibility for producing a blank of a component by individual bending on the first device followed by transfer of the component on the second device for finishing the component. Digital control provides the possibility of shaping one part of the component on the first device and shaping the remaining parts on the second device. The digital control also provides the possibility of using each machine alone and the possibility of using both machines for producing the same component.

Abstract: A digitally controlled machine for bending, forming, or curving raw parts, such as rods, wires or profiled sections, comprises a conventional main frame (1) and a rotating bending head capable of bending articles in different planes. The rod (4) is horizontally displaced along a transport axis (5) by a feed station, located upstream, and is brought through a bending shank (7) borne by the main frame (1). The rod is then brought through a lathe (10) of the bending head. The lathe is formed by a bending roll (8) and a folding pin (9), and is capable of rotating in a horizontal plane about an axis of rotation aligned with the axis of the bending roll (8). The bending shank (7) is movably mounted in translation in a transport axis (5) and is continuously displaced between one or more projecting bending positions wherein the shank is proximate to the roll (8) and one or more retracted positions, facing upstream, which completely clear the bending zone between the lathe and the main frame.
