Description

Title of the invention: Device for shaping a tubular object

[0001] The present invention relates to a device for shaping a tubular object.

[0002] This invention relates to the field of manufacturing tools, more particularly machine tools, which are configured to shape, more particularly to cut, a tubular object, more particularly a tube, in particular a metal tube.

[0003] Such devices for shaping a tubular object are already known.

[0004] Such a shaping device is disclosed in document FR 2835775. This shaping device comprises, on the one hand, a means for shaping the tubular object and, on the other hand, a support means which is configured to bear against the tubular object, in a manner diametrically opposed to the shaping means.This shaping device comprises a first rotary element, which is rotatable about a first axis of rotation, and which comprises, on the one hand, a first arm, one elbow of which is equipped with the shaping means, as well as means for pivotally mounting this first arm within this first rotary element and, on the other hand, a second arm, one elbow of which receives a finger whose free end is equipped with the support means and which comprises means for adjusting the extension length of this finger, as well as means for pivotally mounting this second arm within this first rotary element. This shaping device further comprises a second rotary element, which is rotatable about a second axis of rotation, as well as means for pivotally driving the first and second arms, this within the first rotary element and by the second rotary element.Finally, the shaping device comprises means for driving the first rotary element in rotation around the first axis of rotation as well as the second rotary element around the second axis of rotation.

[0005] This device has a complex design. In addition, in this shaping device, the pivoting amplitude of the first arm and the pivoting amplitude of the second arm are small so that this shaping device only allows the successive shaping of tubular objects of the same diameters. The shaping of tubular objects of different diameters requires, for each of these diameters, a setting and a fine adjustment of the extension length of the finger which is tedious and time-consuming. In addition, this shaping device comprises a single shaping means which wears out quickly and the replacement of which is tedious and time-consuming.

[0006] The present invention aims to remedy, at least in part, the drawbacks of the shaping devices of the state of the art.

[0007] For this purpose, the invention relates to a device for shaping a tubular object. This shaping device comprises, on the one hand, at least one means for shaping a tubular object, on the other hand, a first rotary element, which is rotatable about a first axis of rotation, and which comprises said at least one shaping means as well as means for mounting said at least one shaping means in displacement within this first rotary element, on the other hand again, a second rotary element which is rotatable about a second axis of rotation, on the other hand also, rotational drive means which are configured to rotate the first rotary element about the first axis of rotation as well as the second rotary element about the second axis of rotation and, on the other hand also, means for driving said at least one shaping means in displacement, this within the first rotary element and by the second rotary element.

[0008] The shaping device is characterized in that the rotational drive means comprise a first rotary motor and a second rotary motor as well as an epicyclic gear train which comprises a crown, a sun gear, at least one satellite and a satellite carrier.These rotational drive means also comprise, on the one hand, first input transmission means which are configured to transmit a rotational movement from the first rotary motor to the crown, on the other hand, second input transmission means which are configured to transmit a rotational movement from the second rotary motor to the sun gear, on the other hand again, first output transmission means which are configured to transmit a rotational movement of the crown to the first rotary element and, on the other hand also, second output transmission means which are configured to transmit a rotational movement of the planet carrier to the second rotary element.

[0009] According to another characteristic, on the one hand, the first input transmission means comprise an input toothed wheel, which comprises a first number of input teeth, and which is rotationally fixed to the crown, on the other hand, the first output transmission means comprise a first output toothed wheel, which comprises a first number of output teeth, and which is rotationally fixed to the crown and, on the other hand again, the second output transmission means comprise a second output toothed wheel, which comprises a second number of output teeth, and which is rotationally fixed to the planet carrier.

[0010] Another characteristic concerns the fact that the means for mounting said at least one shaping means in displacement comprise means for mounting said at least one shaping means in radial translation.

[0011] In fact, the radial translation mounting means comprise, on the one hand, at least one guide path which the first rotary element comprises, on the other hand, at least one carriage, which the first rotary element comprises, which cooperates with said at least one guide path. at least one guide path, and which receives said at least one shaping means.

[0012] Yet another characteristic concerns the fact that said first rotary element and / or said second rotary element comprises at least one lateral orifice, which is through, which is located in the extension of said at least one guide path, and which is configured so as to allow the passage of said at least one carriage.

[0013] Thus, the shaping device according to the invention comprises a first rotary motor, a second rotary motor, an epicyclic gear train, (first and second) rotary elements and (input and output) transmission means. These characteristics advantageously make it possible, on the one hand, to ensure a rotation of the (first and second) rotary elements synchronously, more particularly for shaping a tubular object, on the other hand, to ensure a rotation of the (first and second) rotary elements asynchronously, this with an advance of one relative to the other to move said at least one shaping means into the active shaping position and, on the other hand, to ensure another rotation of the (first and second) rotary elements asynchronously, this with a delay of one relative to the other to move said at least one shaping means into the inactive shaping position.

[0014] According to another characteristic, the means for mounting said at least one shaping means in displacement comprise means for mounting said at least one shaping means in radial translation. These characteristics advantageously allow a large amplitude of movement of said at least one shaping means and, thus, the shaping of different tubular objects whose diameters also have a large amplitude, this without adjustment and / or without adjustment and / or without disassembly.

[0015] Yet another characteristic consists in that the first and / or the second rotary element has a through orifice which advantageously makes it possible to extract the carriage provided with a shaping means (more particularly when the latter is worn) from the first rotary element with a view to replacing it and to engage such a carriage (in particular provided with a new shaping means) inside the first rotary element, this in a simple, rapid and easy manner.

[0016] Other aims and advantages of the present invention will appear during the description which follows relating to embodiments which are given only as indicative and non-limiting examples.

[0023] The present invention relates to the field of tool manufacturing, more particularly the field of machine tool manufacturing, which are configured to shape, more particularly to cut, a tubular object, more particularly a tube, in particular a metal tube.

[0024] The invention then relates to a device 1 for shaping a tubular object.

[0025] This shaping device 1 comprises at least one shaping means (2; 2') of a such tubular object. According to a preferred embodiment of the invention, this shaping device 1 comprises two shaping means (2; 2') while the shaping device 1 is configured so that these two shaping means (2; 2') are positioned opposite each other, on either side of the tubular object to be shaped. According to a preferred embodiment, such shaping means (2; 2') comprises (or is constituted by) a wheel or the like.

[0026] This shaping device 1 also comprises a first rotary element 3 which is movable in rotation around a first axis of rotation XL

[0027] As can be seen in the attached figures, such a first rotary element 3 comprises at least one plate 30, which takes the form of a disc, and which is movable in rotation around the first axis of rotation XL.

[0028] This first rotary element 3 also comprises said at least one shaping means (2; 2') as well as displacement mounting means 4 which are configured to mount said at least one shaping means (2; 2') in displacement within this first rotary element 3.

[0033] It is, more particularly, such a carriage (41; 41') which receives (more particularly which is equipped with) said at least one shaping means (2; 2').

[0034] In this regard, it will be observed that, according to a preferred embodiment of the invention, these displacement mounting means 4 (more particularly these radial translation mounting means), on the one hand, are configured to mount two shaping means (2; 2') in displacement within this first rotary element 3 (this in the manner mentioned above and symmetrically with respect to the first axis of rotation XI) and, on the other hand, comprise two guide paths (40; 40') as well as two carriages (41; 41'). In this case, these two guide paths (40; 40') are symmetrical with respect to the first axis of rotation XI and are located in the extension of one (40; 40') of the other (40'; 40).

[0035] According to another characteristic, the shaping device 1 further comprises a second rotary element 5 which is movable in rotation around a second axis of rotation X2. This second axis of rotation X2 is at least parallel to the first axis of rotation XI, or even coincident with this first axis of rotation XL. As visible in the figures in the appendix, this second rotary element 5 is positioned opposite the first rotary element 3.

[0036] This second rotary element 5 may comprise at least one plate 50, which adopts the shape of a disc, and which is movable in rotation around the second axis of rotation X2.

[0037] Yet another feature concerns the fact that the shaping device 1 also comprises rotational drive means 6 which are configured to drive the first rotary element 3 in rotation around the first rotation axis XI as well as the second rotary element 5 around the second rotation axis X2.

[0038] In this regard, it will be observed that these rotational drive means 6 comprise a first rotary motor 7 (which comprises a stator as well as a rotor which is movable in rotation relative to the stator as well as around an axis of rotation which is at least parallel to the first axis of rotation XI and / or to the second axis of rotation X2) as well as a second rotary motor 8 (which comprises a stator as well as a rotor which is movable in rotation relative to the stator as well as around an axis of rotation which is at least parallel to the first axis of rotation XI and / or the second axis of rotation X2).

[0039] These rotation drive means 6 also comprise an epicyclic gear train 9 which comprises a crown 90 (more particularly which is rotatable about an axis of rotation Xt which is at least parallel to the first axis of rotation XI and / or to the second axis of rotation X2), a sun gear 91 (more particularly which is rotatable about an axis of rotation which is at least parallel to the first axis of rotation XI and / or to the second axis of rotation X2 and / or to the axis of rotation Xt around which the crown 90 is rotatable, or even coincident with the axis of rotation Xt around which the crown 90 is rotatable),at least one satellite 92 (more particularly which cooperates with the crown 90 as well as with the sun gear 91 and which is rotatable about an axis of rotation which is at least parallel to the first axis of rotation XI and / or to the second axis of rotation X2 and / or to the axis of rotation Xt about which the crown 90 is rotatable) and a planet carrier 93 (more particularly which receives said at least one satellite 92 and which is rotatable about an axis of rotation which is at least parallel to the first axis of rotation XI and / or to the second axis of rotation X2 and / or to the axis of rotation Xt about which the crown 90 is rotatable, or even coincident with the axis of rotation Xt about which the crown 90 is rotatable).

[0041] In this regard, it will be observed that, on the one hand, the first input transmission means 10 comprise an input toothed wheel 100, which comprises a first number of input teeth NE1, and which is integral in rotation with the crown 90 (more particularly in rotation around the axis of rotation Xt around which this crown 90 is movable in rotation), on the other hand, the first output transmission means 12 comprise a first output toothed wheel 120, which comprises a first number of output teeth NSI, and which is integral in rotation with the crown 90 (more particularly around the axis of rotation Xt around which this crown 90 is movable in rotation) and, on the other hand, the second output transmission means 13 comprise a second output toothed wheel 130, which comprises a second number of output teeth NS2, and which is integral in rotation with the planet carrier 93 (more particularly around the axis of rotation Xt around which the crown 90 is movable in rotation).

[0042] In this regard, it will be observed that the first number of input teeth NE1 and the first number of output teeth NSI are preferably identical.

[0043] Yet another feature is that the first rotary motor 7 includes a toothed wheel 70.

[0044] Alternatively or (and preferably) additionally, the first rotating element 3 comprises a toothed wheel 31.

[0045] Alternatively or (and preferably) additionally, the second rotating element 5 comprises a toothed wheel 51.

[0046] In particular, the toothed wheel 31 of the first rotating element 3 and the toothed wheel 51 of the second rotating element 5 may have the same number of teeth.

[0047] According to a first embodiment not shown, the toothed wheel 70 of the first rotary motor 7 cooperates (more particularly directly) with the input toothed wheel 100 of the first input transmission means 10. Alternatively or (and preferably) additional to this first embodiment, the toothed wheel 31 of the first rotary element 3 cooperates (more particularly directly) with the first output toothed wheel 120 of the first output transmission means 12. Alternatively or (and preferably) additional to this first embodiment, the toothed wheel 51 of the second rotary element 5 cooperates (more particularly directly) with the second output toothed wheel 130 of the second output transmission means 13.

[0048] According to a second embodiment illustrated in the appended figures, the first input transmission means 10 further comprise at least one belt 101, in particular a toothed belt.

[0050] Alternatively or (and preferably) additionally, the belt 121 of the first output transmission means 12 cooperates at least with the first wheel output toothed wheel 120 of the first output transmission means 12, or even with the toothed wheel 31 of the first rotary element 3.

[0051] Alternatively or (and preferably) additionally, the belt 131 of the second output transmission means 13 cooperates at least with the second output toothed wheel 130 of the second output transmission means 13, or even with the toothed wheel 51 of the second rotary element 5.

[0052] According to another characteristic, the first output transmission means 12 have a first transmission ratio while the second output transmission means 13 have a second transmission ratio.

[0053] Also and according to another characteristic, the first transmission ratio of the first output transmission means 12 and the second transmission ratio of the second output transmission means 13 are configured so that the first rotary element 3 and the second rotary element 5 rotate synchronously.

[0054] To do this and according to a particular embodiment, the second number of output teeth NS2 is greater than the first number of output teeth NSI. According to a specific embodiment, the first number of output teeth NSI is 99 while the second number of output teeth NS2 is 100. In such a case, the number of teeth of the toothed wheel 31 of the first rotary element 3 may be equal to the number of teeth of the toothed wheel 51 of the second rotary element 5.

[0055] However and according to another embodiment, the number of teeth of the toothed wheel 31 of the first rotary element 3 is greater than the number of teeth of the toothed wheel 51 of the second rotary element 5. In such a case, the second number of output teeth NS2 may be equal to the first number of output teeth NSI.

[0056] As mentioned above, the shaping device 1 comprises means 4 for mounting said at least one shaping means (2; 2') in displacement which comprise means for mounting said at least one shaping means (2; 2') in radial translation which comprise at least one guide path (40; 40') as well as at least one carriage (41; 41').

[0057] In this regard, it will be observed that, according to an additional characteristic, said first rotary element 3 and / or said second rotary element 5 comprises at least one lateral orifice 14, which is through, which is located in the extension of said at least one guide path (40; 40'), and which is configured so as to allow the passage of said at least one carriage (41; 41'). The presence of such a lateral orifice 14 advantageously allows the extraction of at least a part of such a carriage (41; 41') from the first rotary element 3 (in particular with a view to its complete extraction from this first rotary element 3 with a view to its replacement and / or the replacement of its shaping means 2; 2') as well as the introduction of such a carriage (41; 41') to inside this first rotating element 3.

[0058] The shaping device 1 further comprises displacement drive means 15 which are configured to drive said at least one shaping means (2; 2'), this within the first rotary element 3 and by the second rotary element 5.

[0059] In fact, these movement drive means 15 are, more particularly, configured to drive said at least one shaping means (2; 2'), this between at least one inactive shaping position and at least one active shaping position.

[0060] In this regard, it will be observed that these movement drive means 15 are, then, more particularly, configured to drive said at least one carriage (41; 41'), this between at least one such inactive shaping position and at least one such active shaping position.

[0061] Additionally, these movement drive means 15 may also be configured to drive said at least one carriage (41; 41') from a retracted position inside the first rotary element 3 and an at least partly deployed position outside the first rotary element 3, more particularly through said at least one lateral orifice 14.

[0062] These displacement drive means 15 comprise (or are constituted by) radial translation drive means (more particularly in the direction of a radius which passes through the first axis of rotation XI) of said at least one shaping means (2; 2'), more particularly of said at least one carriage (41; 41').

Such a follower (151; 151') can adopt the form of a roller, a stop, a stud or the like.

[0064] In the remainder of the description, the operation of the shaping device 1 will be described with reference to the technical characteristics described above.

[0065] According to a first mode of operation of the shaping device 1, the first rotary motor 7 operates while the second rotary motor 8 is stopped.

[0066] In this first mode of operation, the first rotary element 3 and the second rotary element 5 rotate synchronously, more particularly due to the appropriate configuration of the first transmission ratio of the first output transmission means 12 and the second transmission ratio of the second output transmission means 13 as described above.

[0067] According to a second mode of operation of the shaping device 1, the first rotary motor 7 is stopped while the second rotary motor 8 is operating.

[0068] In this second mode of operation, the displacement drive means 15 (more particularly said at least one cam 150; 150') ensure a displacement drive (in radial translation) of said at least one shaping means (2; 2'), more particularly between a retracted position of said at least one carriage (41; 41') inside the first rotary element 3 and an at least partially deployed position of said at least one carriage (41; 41') outside the first rotary element 3 (more particularly through said at least one lateral orifice 14) and vice versa.

[0069] According to a third mode of operation of the shaping device 1, the first rotary motor 7 and the second rotary motor 8 operate, more particularly continuously.

[0070] In this third mode of operation, the displacement drive means 15 (more particularly said at least one cam 150; 150') ensure a displacement drive (in radial translation) of said at least one shaping means (2; 2'), either between at least one inactive shaping position and at least one active shaping position, or between at least one active shaping position and at least one inactive shaping position, depending on the direction of rotation of the second rotary motor 8.
