Definitions
- leading edge of these composite blades is too sensitive to erosion and possible shocks (birds, gravel, ice, sand, etc.) to be used without protection. This is why it is known to protect this leading edge with a protective reinforcement.
- journal make it possible to permanently hold the sheet in position during the stamping operation, while allowing an opposite shaping between the two ends of the sheet (without shearing the connection between the journals and the plate).
- the first pin thanks to said peripheral groove, contributes to the lateral and longitudinal positioning of the part, while the second pin contributes to the lateral positioning of the part.
- each pin is equipped with a pin extending through said slot.
- each pin may have a hole that intersects the slot and is configured to receive the pin.
- the sheet has a hole configured to be traversed by the pin. The pin, in association with the slot, makes it possible to make the plate integral with each pin, in particular to make these elements integral in rotation about the axis of rotation of the pin and in translation along this axis.
- said pin is removable so that the journals can be separated from the sheet after stamping and reused with another sheet.
- the device further comprises two second columns, each extending along a main axis substantially perpendicular to the axis of rotation of the second journal, these second columns being configured to receive the second journal, the second columns being disposed on either side of the second pin so as to block the translation of the second pin in a direction perpendicular to said main axes and said axis of rotation, while allowing the translation of the second pin along its axis of rotation.
- the present disclosure also relates to a method of shaping a sheet by stamping, in which the device described above is used, the first and second pins of the device being fixed respectively to said opposite ends of the sheet.
- FIG 3 is a front view of the first pin of FIG 1.
- FIG 7 is a perspective view of the lower die used to shape the sheet of FIG 1.
- FIG 8 is a perspective view of the upper die used to shape the sheet of FIG 1.
- the two notches 28A, 28B formed on either side of the pin 20 form around it an outer peripheral groove 28, this groove 28 extending perpendicularly to the axis of rotation RI.
- the bottom surface 29A, 29B of each notch 28A, 28B has a generally semicylindrical general shape, about the axis RI. These surfaces 29A, 29B appear in dotted lines in FIG.
- the bottom brackets 29A, 29B serve as a bearing surface when the journal 20 is rotated about the axis R1.
- the second pin 30 comprises a cylindrical pin 39 defining a cylindrical lateral surface 33 of revolution having as an axis of revolution the axis of rotation R2.
- This cylindrical lateral surface 33 serves as a bearing surface during the rotation of the pin 30 around the axis R2.
- the tongues 12, 13 both have a hole (not shown) which passes through their thickness. It is understood that by inserting the tongues 12, 13 in the slots 21, 31, and by making the holes of the tongues 12, 13 coincide with the holes 24, 34 of the journals 20, 30 and by embedding the pins 25, 35 in these holes, it prevents relative movement between the journals 20, 30 and the sheet 10.
- the journals 20, 30 are integral in rotation of the sheet 10, about the axes RI and R2.
- This example device also comprises two first columns 51, 52 respectively extending along main axes A1, A2 parallel to each other and perpendicular to the axis of rotation RI.
- Each column 51, 52 has a beveled upper end defining first, second and third flats 53 to 55.
- the first two flats 53 of the two columns face each other and define between them a "V" spacing facilitating the placement of the first pin 20 between the first two columns 51, 52, while the second and third flats 54, 55 of the same column are opposite to the main axis Al (A2) of the column 51 (52) so that the the upper end of the column is tapered.
- This tapered end facilitates the passage of the columns 51, 52 in the external peripheral groove 28 of the journal 20 (more precisely in the notches 28A, 28B, respectively).
- the device further comprises: two second columns 61, 62 each extending along a main axis B1, B2 perpendicular to the axis of rotation R2 of the second journal 30.
- the second columns 61, 62 each have a beveled upper end defining a flat 63.
- the two flats 63 of the two columns face each other and define between them a spacing "V" facilitating the establishment of the second pin 30 between the second columns 61, 62.
- the device also comprises upper and lower matrices 80 configured to receive the sheet 10 between them and to put this sheet 10 in shape by stamping.
- These matrices 70, 80 are shown in FIGS. 7 and 8. These figures 7 and 8 are diagrammatic, in particular with regard to the imprints of the dies.
- the four columns 51, 52, 61, 62 are carried by the lower die 70 and are fixed thereto, as shown in FIG. 7.
- the lower die 70 also has cavities 71, 72 to respectively receive the journals 20 and 30 during the approximation of the matrices.
- the upper die 80 has, for its part, cavities 81, 82 for respectively receiving the pins 20 and 30 during the approach of the dies, and other cavities 83 for receiving the free ends of the four columns 51, 52, 61, 62 when the matrices are brought together.
- the embedding of the journals 20, 30 between the columns 51, 52, 61, 62 makes it possible to ensure the lateral and longitudinal positioning of the sheet 10 with respect to the matrices 70, 80, before and during the shaping (ie the stamping) of the sheet.
- this embedding allows the rotation of the pins, and therefore the sheet during the shaping thereof.
- opposite rotations of the two end portions of the sheet 10 are possible.
