Embodiment Construction

[0050] The treatment plant according to the invention shown in the figures comprises a plant for the thermal hardening of rod-shaped or tubular metal elements, for example suspension elements of motor vehicles, which may in particular include: the torsion bar 1 shown in the figures.

[0051] The processing equipment first includes:

[0052] The means 2 for fixing the metal element 1, comprising a clamp, arranged in the vicinity of said upper end section of said metal element, so that the metal element is freely suspended below said clamp,

[0053] Means for moving the gripper 2, adapted to translate the gripper on the one hand along a vertical axis (z) and a horizontal axis (y) and on the other hand around a vertical axis (z) and a horizontal plane perpendicular to the plane (y, z) Axis (x) rotates the fixture.

[0054] Firstly, the clamp consists of a tubular clamp 2 of the free-scissors type, comprising a rotary part separated along several generatrix points, so that by its...

Abstract

The invention relates to a device for treating, by heat tempering, a metal element (1) of the tube or bar type having arched portions. Said device comprises heat treatment means having an induction coil (23) and a sparger ring (26). According to the invention, this device comprises means (2) for holding the metal element (1) that consist of a clip (2) arranged so as to clamp around an end portion,referred to as the top, of the metal element and to keep said metal element freely suspended under said clip; and movement means (24, 28) suitable for moving the induction coil (23) and the sparger ring (26) simultaneously along the metal element (1) starting from an end portion, referred to as the bottom, of said metal element that is opposite the top portion thereof.

Description

technical field [0001] The invention relates to a device for heat quenching treatment of tubular or rod-shaped metal elements having curved sections. [0002] More specifically, the present invention relates to a kind of heat treatment equipment, mainly comprises: [0003] heat treatment means, including induction coils, and cooling means, including nozzles integrated into the annular spray head; [0004] Devices for fixing metal elements; [0005] And the relative displacement means of the metal element fixing means and the heat treatment means are adapted to generate said metal element relative displacement within the induction coil and the spray ring arranged adjacent to each other. Background technique [0006] According to the first solution specifically described in US2011 / 284526 patent application, the heat treatment equipment according to this concept includes a fixed bracket on which a plurality of clamps each having two jaws are fixed, these clamps: [0007] - s...
