Definitions
- the invention relates to the field of devices and methods for embedding a part in a ring. More specifically, the invention relates to the field of such devices and methods for the manufacture of analysis samples, in particular samples having a radioactive activity.
- a known solution in order to decrease the radioactive doses of the samples and to decrease the activation energy is to reduce the size of the sample.
- a sample is usually in the form of a disk approximately 3 mm in diameter made from a plate approximately 100 ⁇ m thick and cut with rooms. The sample then undergoes electrochemical polishing on both sides. We then obtain two concave faces with a hole substantially in the center. This diameter of 3 mm is too large for a sample of radioactive material for the security reasons discussed above.
- this diameter is reduced to about 1 mm; the radiation is then divided by about 10.
- these discs of about 1 mm in diameter are embedded in a ring whose outside diameter is about 3 mm and the inside diameter of about 1 mm.
- the embedding of a part in a ring is usually done in the following way: punching a plate of the material to be studied in order to obtain a part, this operation is best carried out in a glove box; - transfer the piece to a ring of a non-radioactive and non-magnetic material with a forceps by a human operator; embed the piece in the ring by pressing either vertically or applied with a roller.

- a guiding assembly for guiding the punch, the workpiece and the counter punch along their stroke; -
- the punch stroke and the stroke of the counter punch being adapted to stop when the piece is embedded in the ring.
- the invention also proposes a method for embedding a part in a ring, characterized in that it comprises the following steps: - maintaining a ring by the ring retainers; to put in cooperation a punch housed in an axial holding housing of the punch, mobile in a stroke relative to the housing and a counter punch, movable in a stroke relative to the supports, for punching a plate at the end of the punch , so as to form a part to be embedded in the ring;
- An advantage of such a device and of such a method is to allow the manufacture of radioactive samples in a secure medium, for example within an armored cell.
- the device further comprises a support of the plate adapted to support the plate; the holders of the ring and the support of the plate comprise a common element; - The device further comprises stops to define the punch stroke and / or the stroke of the punch-punch; the guide assembly is a set of bores made in the holders of the ring, the support of the plate and housing and axially centered on the same axis; the counter-punch comprises a centering finger for axially centering the ring on the axis of the bores.
- the method comprises the step of positioning the ring in a retaining fingerprint of the ring provided in the housing; the guide of the punch, the workpiece and the counter-punch is carried out along a single axis when the guide assembly is a set of bores made in the holders of the ring, the support of the plate and the housing; the method comprises the step of centering the ring held by a centering finger provided on the counter punch.

- the device 1 of the invention for embedding a part 4 'in a ring 6 comprises:
- - Holders 3, 25 of the ring able to hold a ring 6 stationary; a punch 11 housed in a housing 15 for axially holding the punch, movable in a stroke relative to the housing 15 for punching a plate 4, at the end of the punch 11; a counter-punch 21, movable in a stroke relative to the supports 3, 25, to cooperate with the punch 11 so as to form a part 4 'to be embedded in the ring 6; a guiding assembly 17, 27, 37 for guiding the punch 11, the piece 4 'and the counter-punch 21 along their stroke.
- the stroke of the punch 11 and the stroke of the punch 21 are adapted to stop when the piece 4 'is embedded in the ring 6 as explained in the following description.
- the stroke of the punch 11 and the stroke of the counter punch 21 are substantially axial with respect to the punch 11 and against the punch 21. This will be described in more detail later in this description.
- the plate 4 is made of a material to be studied and / or analyzed and of a thickness suitable for study and / or analysis.
- the plate 4 has a thickness of about 100 microns.
- the built-in part 4 ' is formed in the plate 4 by punching.
- the size of the room 4 ' is suitable for study and / or analysis.
- the piece 4 ' is a disc about 1 mm in diameter.
- the ring 6 is made from a plate of a material suitable for the study and / or analysis of the piece 4 '.
- the plate is made of a non-radioactive material, non-magnetic and has a thickness of about 100 microns. The plate can be mechanically thinned beforehand.
- the ring 6 can be formed by cutting the plate of suitable material using a punch.
- the ring 6 can be of various shape conferred by the punch.
- the ring may be circular about 3 mm in outer diameter.
- the ring 6 has an inner orifice 62 adapted to receive exactly the piece 4 '.
- the inner hole has a circular shape of about 1 mm in diameter (see Figure 4).
- the configuration of the device 1 thus produced makes it possible to manufacture samples inside a shielded cell since the punching to form the part 4 'and the embedding in the piece 6 are made in a single stroke of the punch 11 and counter punch 21.
- the device 1 makes it possible, for example, in the case of manufacturing radioactive samples, to limit transfers of radioactive materials from one instrument to another generally requiring manipulation by an operator. In this same case, it makes it possible to comply with safety standards in terms of radiation protection.
- the holders of the ring 3, 25 force the ring 6 to remain flat during the embedding of the piece 4 '.
- the holders 3, 25 of the ring may also comprise a recess 251 for positioning the ring.
- the guide assembly 17, 27, 37 makes it possible to center the piece 4 'relatively to the ring 6 and to obtain a precise embedding.
- the holdings of the ring 3, 25 and the guide assembly make it possible to obtain samples without burrs.
- a support 3 of the plate 4 may also be provided in the device 1 in order to support the plate 4 of material to be studied and / or analyzed.
- This support 3 may comprise cutting edges 31 cooperating with the punch 11 in order to cut without burring the piece 4 'in the plate 4.
- the holders of the ring 3, 25 and the support 3 of the plate may comprise a common element 3.
- This common element holds the ring 6 by being placed in the upper position of the ring 6 and supports the plate 4 by being placed in the lower position of the plate 4.
- Stops 18 and 18 ' may be provided, respectively, to delimit the stroke of the punch 11 and the stroke of the counter punch 21.
- the guide assembly 17, 27, 37 may be a set of bores axially centered on the same axis AA. These bores 17, 27, 37 are made through the supports 3, 25 of the ring, the support 3 of the plate and the housing 15.
- the punch 11 and the counterpunch 21 are configured to be able to pass through these bores with minimal clearance to ensure easy sliding smoothly.
- the counterpunch 21 comprises a centering pin 211 for axially centering the ring 6 on the axis AA of the bores.
- This finger 211 may, for example, be the end of the countersunk punch 21 chamfered.
- An advantage associated with the use of a centering finger 211 is to allow centering of the ring 6 easier. Indeed, because of the size of the ring 6, it is not easy to position the ring 6 so that its axis of revolution or symmetry is perfectly aligned with the axis AA of the bores.
- the punch 11 and the counter-punch 21 move by manual or automatic actuation via hydraulic cylinders or gear mechanism with crank. Their displacement is carried out inside the supports 3, 25, of the support 3 of the plate and the housing 15.
- the manufacturing method of the ring 6 with embedded part 4 ' comprises the following steps: maintaining the ring 6 by the holds 3, 25 of the ring 6; cooperating the punch 11 and the counter-punch 21 to punch the plate 4 at the end of the punch 11, so as to form the part 4 'to be embedded in the ring 6 (see Figure 2); guiding the punch 11, the piece 4 'and the counter-punch 21 along their stroke by the guide assembly 17, 27, 37; and stop the stroke of the punch 11 and the counter-punch 21 when the piece 4 'is embedded in the ring 6 (see Figure 3).
- the method comprises one or more of the following steps: positioning the ring 6 in a cavity 251 for holding the ring provided in the housing 15; - Center the ring 6 held by a centering finger 211 provided on the counterpunch 21.
- the guide of the punch 11, the part 4 'and the counterpunch 21 is performed along a single axis AA when the guide assembly 17, 27, 37 is a set of bores made in the holders 3, 25 of the ring, the support 3 of the plate and the housing 15.
- Stopping the strokes of the punch 11 (during embedding of the piece 4 'in the ring 6) and against the punch 21 (when in cooperation with the punch 11 and / or the recess of the piece 4 'in the ring 6) can be performed by means of the stops 18'.
- the mechanical strength of the piece 4 'in the ring 6 is also improved and allows easier handling without fear that the piece 4' is loose.
- FIG. 5a shows the crystalline state of the part 4 'embedded in the ring 6 near a so-called embedding zone 8 (visible in FIG. 4).
- the embedding zone 8 is the zone in the vicinity of the ring / workpiece interface. This image was taken on such a sample after a hole was made, electrochemically, near the embedding zone 8, about 0.15 mm from it. The image was taken by MET.
- Figure 5b shows the crystalline state of a sample used in the prior art, as described in the preamble of the application.
- the device 1 and the method it implements induce a density of dislocations in the manufactured sample of 1 mm equivalent to the density of dislocations obtained in a sample of 3 mm, used by the prior art.
