Definitions
- Apparatus for free-form bending of longitudinal profiles, in particular tubes and combined apparatus for free-form bending and drawing bending of longitudinal profiles, in particular tubes
- the invention relates to a device for free-form bending of longitudinal profiles, comprising a feed unit which detects the longitudinal profile, with an axial sleeve which is downstream of the feed unit in positive and / or frictional engagement, and with a bending sleeve arranged downstream of the axial sleeve in the feed direction, with an outer contour the longitudinal profile adapted through opening for the longitudinal profile, wherein the bending guide by means of actuators in a direction orthogonal to the axis of its passage opening plane is linearly adjustable and about a perpendicular to both the axis of the passage opening and the direction of the linear adjustment axis is pivotable and wherein the axial sleeve with a drive equipped with their distance from the bending sleeve is adjustable.
- a known device for free-form bending differs from the aforementioned device in that the axial profile leading the longitudinal profile is arranged stationary and thus its distance from the bending sleeve is not adjustable.
- the bending sleeve is mounted on a cross slide, with which it can be adjusted in two transverse to the longitudinal axis of the longitudinal profile orthogonal axes.
- the bending guide is pivotable about two mutually and perpendicular to the axis of its passage extending axes. Finally, it is rotatable about the axis of its passage opening. For all these possibilities of movement own drives and bearings are provided. To accommodate these parts on the bending guide, considerable space is needed. This place limits not insignificantly the smallest possible bending radius.
- the mechanical engineering effort is relatively high.
- the invention has for its object to provide a device for free-form bending of longitudinal profiles, especially pipes, which is designed easier in their design effort than the known device and also allows very small bending radii.
- the axial sleeve By reducing the adjustments required for free-form bending and relative movements - the axial sleeve needs only one drive for a translational movement and a drive for a pivoting movement with corresponding bearings, while for the rotatable or controlled braced storage of the bending sleeve needs to be provided only a brake and the initiation of a bend in space by rotation of the longitudinal profile is formed by a simultaneous rotation of the feed unit and the axial sleeve - results in a very simple structural design and a short overall length.
- the distance between the bending sleeve and the axial sleeve can be set individually for the respective bending case, there is the possibility that longitudinal profiles, in particular tubes, can be bent with a comparatively small bending radius.
- the feed unit is formed in a conventional manner as a fitted with a feed drive collet.
- support means can be provided in the region between the feed unit and the axial sleeve, which hold the longitudinal profile exactly in the profile axis.
- these support means In order to avoid a collision of these support means with the advancing during advancing feed unit, these support means must be designed so that they release the path of the feed unit.
- a plurality of successively arranged lunettes are suitable, which can be opened and moved to the side.
- a flexible inner mandrel can be arranged in the bending region in and after the axial sleeve as far as into the bending sleeve, its axial position is adjustable and controllable via a mandrel rod provided with the drive from the rear end of the feed unit.
- the inventive device for free-form bending of longitudinal profiles is particularly suitable because of the described splitting of the required for free-form bending different settings with drives and bearings to be combined with a device for drawing bending, because parts of the device both for free-form bending and for Pull bending can be used.
- other devices for free-form bending than the invention can be combined with a device for draw bending according to this inventive solution.
- 1 is a device for free-form bending with its essential parts and drives in a highly schematic representation in an isometric view obliquely from above
- FIG. 2 shows the device according to FIG. 1 with a tube to be bent in an isometric view from obliquely above from a different angle to FIG. 1, FIG.
- Fig. 3 shows a combined device for free-form bending and drawing bending in a schematic representation in plan view.
- the device shown in FIGS. 1 and 2 for free-form bending of a longitudinal profile 1, in particular a tube, has a feed unit 2 in the form of a collet known per se, one in front in the feed direction arranged axial sleeve 3 and in turn in the feed direction arranged bending sleeve 4 with a passage opening 4a.
- the bending sleeve may be formed as a sliding sleeve. But it can also have a roller guide. Both alternatives serve to be able to move the tube 1 through the passage opening 4a with as little friction as possible.
- a flexible mandrel 5 which is held at the rear end of the tube 1 via a mandrel 6.
- the mandrel 6 is connected to a drive 7, so that the mandrel 5 is axially adjustable and controllable.
- Trained in particular as a pipe collet feed unit 2 has an axial drive 8, which is shown schematically in the drawing by a double arrow.
- the feed unit 2 has a rotary drive 9, which is represented by a double arrow.
- the axial sleeve 3 is also associated with a rotary drive 10, which is represented by a double arrow.
- the rotary actuators 9 and 10 rotate in the same direction and simultaneously.
- the axial sleeve 3 is associated with an axial drive 11, which is represented by a double arrow.
- the axial drives 8 and 11 operate independently. With the axial drive 11, the distance from the longitudinally-axially fixed bending sleeve 4 can be adjusted.
- the bending sleeve 4 has a translatory drive 12, which is represented by a double arrow.
- the bending sleeve 4 has a pivoting drive 13 which represented by a double arrow.
- the bending sleeve 4 has a pivot bearing 14, which is represented by a double arrow.
- the pivot bearing 14 is designed such that when the longitudinal profile 1 to be bent, this transmits the rotational movement of the axial sleeve 3 on the bending sleeve 4, so that it is taken freely rotating.
- this pivot bearing 14 is equipped with a brake, so that there may be a rotation angle offset between the two parts. This is desirable when the longitudinal profile 1 is to be twisted.
- the spatial axes x, y, z shown in the drawing are fixed for the axial sleeve 3
- the spatial axes u, v, w for the bending sleeve 4 are displaceable in space.
- the bending sleeve 4 in the axial direction, i. is fixed in the direction of the w axis, but it is co-rotating or braked about this w axis. In the direction of the u-axis, it is translationally adjustable by means of the drive 12 and rotatable about the v-axis by means of the drive 13.
- the bending plane is always in the u / v plane.
- a second bend in another direction can be connected to a first bend.
- the bending radius is determined on the one hand by the distance between the axial sleeve 3 and the bending sleeve 4 and on the other hand by the settings on the bending sleeve 4, in the direction of the u-axis, and about the v-axis.
- lateral support means not shown in the drawing can be provided in this area.
- they are formed as a package of lunettes, which can be opened according to the feed path of the feed unit 2 and moved out of the way.
- the apparatus shown in the embodiment of FIG. 3 is designed both for free-form bending and for drawing bending. Both for free-form bending and drawing bending, the device has a common feed unit 2, which can be designed as a collet chuck. It is stationary, ie not moved to the side. Before the feed unit 2 there is a support frame 15 which has two independent bending units Ba, B 2 , which are laterally movable by means of drives Pi, P 2 shown by double arrows.
- the bending unit Bi is in parking position while the bending unit B 2 - is in working position.
- the bending unit Bi is configured for free-form bending according to the above-described bending apparatus, while the bending unit B 2 is designed for the drawing bending.
- the bending unit B 2 for the draw bending has, in a manner known per se, a radius template 16a, a clamping jaw 16b, a fold smoother 16c and a slide rail 16d as main components.
- a radius template 16a a radius template 16a
- a clamping jaw 16b a clamping jaw 16b
- a fold smoother 16c a slide rail 16d as main components.
- the bending unit B 2 In order to convert the device from draw bending to free-form bending, only the bending unit B 2 needs to be moved to its parking position and the bending unit B x for free-form bending from its parking position to the working position in front of the stationary feed unit 2.
