Abstract:
The invention relates to a riveting element (R) for riveting parts which are made from composite materials (M1 and M2) and provided with a through-hole. The invention is characterized in that it consists of: a hollow bushing (200) including, at one end, a head (210) bearing on the surface of one of the parts to be assembled and a hollow rod (220); and a semi-tubular insert (100) including a first end (110) capable of being inserted into the hollow part of the bushing (200) and an open end (130) capable of deforming in order to form an enlarged base that bears on the surface of the other part that is to be assembled once the insert (100) is translatably locked inside the bushing (200). The invention also relates to the installation tool configured for one such element.
Abstract:
The invention relates to a method for installing a rivet (R, R′, R″, R2) for the purpose of assembling at least two elements (300, 400) through which a hole passes, in which the rivet (R) is positioned in said hole and is of the type comprising a head (100) coming to rest on the edge of the hole and a tubular or semi-tubular rod (200) of which the free open end (220) is deformed, for the purpose of creating a bearing surface, in which a snap (B, B′) ensures the deformation of said free end (220) by bringing the snap (B, B′) toward the first tool,remarkable in that it consists of interposing a film (500, 600, 700) of material between the snap (B, B′) and the end to be deformed during installation.The invention also relates to a corresponding rivet and installation tool.Applications: rivet installation.
Abstract:
Disclosed is blind rivet including a hollow sleeve, a crimping ring, and a mandrel, received by the hollow sleeve and by the crimping ring. The mandrel includes a head configured to bear against the sleeve, and a shank configured to receive a traction load from a tool. There is a breaking groove which breaks off when the traction load reaches a certain value. The breaking groove including a breaking groove bottom, a first breaking-groove-side extending from the breaking groove bottom toward the shank, a second breaking-groove-side extending from the breaking groove bottom towards the head. A first breaking-groove-side and a central axis of the mandrel define a first angle, and a second breaking-groove-side and the central axis define an angle greater than the first angle. An embrittlement groove is contiguous with the first breaking-groove-side.
Abstract:
Disclosed is a system of displacing a plurality of parts to be stocked and distributed, each part defining a first end and a second end. The system comprises a conduit, the conduit defining an interior to house an actuation fluid, an axis of displacement in the interior, and an interior surface; and a plurality of devices. Each device includes a periphery configured to contact the interior surface of the conduit and to move along the interior surface, a device first surface approximately perpendicular to the axis of displacement, the device first surface being subject to a pressure of the actuation fluid thereby subjecting the device to displacement in the conduit, a first device-end shaped to receive the first end of a corresponding first part in the plurality of parts, and a second device-end shaped to receive the second end of a corresponding second part in the plurality of parts. The second device-end defines a recess including a bottom surface intersected by the axis of displacement, the recess being configured to center the corresponding second part in the conduit. The device is positioned between the corresponding first part and the corresponding second part in the conduit.
Abstract:
The invention relates to a device (D) that enables the displacement of a part (P) inside a conduit (T) inside of which a moving fluid circulates. This device is characterized by being comprised of a body (100) that, when being assigned to each part (P), has at least one portion of its periphery (110) that comes into guiding contact with the inner surface (200) of the conduit (T) inside of which the parts (P) should move, and has at least one supporting surface essentially perpendicular to the axis of displacement inside the conduit (T) for the displacement fluid, the two ends (120, 130) of the device (D) being pre-shaped for accommodating and centering the parts (P) with those with which it is in contact. The device is used for storing and distributing parts inside a conduit.
Abstract:
The invention relates to a blind rivet (R) of the type which is used to position at least two elements (100 and 200) alongside one another and to fasten same and which is installed using an installation tool. The invention is characterised in that it comprises a bushing (300) which is made from one single piece and which is preformed from a single tapered part (330) that is located between the two support surfaces (311 and 321), with the elements to be assembled being defined initially or by means of deformation by the bushing. The invention also relates to a method of removing said rivet.
Abstract:
The invention relates to a fastener member for the production of assemblies, in particular a rivet. This fastener means includes a shank (1) and a head (2) intended to be deformed by flattening during installation. On its front face, this head has an annular groove (5) extending around the axis and positioned in proximity to the alignment of the exterior surface of the shank. This groove defines on the head two portions, one central (2C), the other peripheral (2P), able to be deformed independently under the effect of flattening. The invention enables a considerable improvement of the distribution of compressive forces between the fastener means and the materials to be assembled. It assures a satisfactory radial expansion of the head, as well as a sufficient flow of material toward the shank and the junction zone between shank and head.
Abstract:
The invention relates to a method of remi-neralization and correction of pH for water produced by a fuel cell (P) on board an aircraft, noteworthy in that it consists in diverting part of the water (E1) produced by the cell to at least one treatment tank (200) containing a saturation reagent and in mixing the flow of treated water (E2) issuing from the treatment tank (200) with the undiverted flow of water (E3) so as to obtain water (E5) with the desired mineralization and/or pH. The invention also relates to devices making it possible to implement said method.
