Definitions
- the present invention relates to a method of fixing a roof flag on the body of a motor vehicle.
- the roof pavilion of many of today's motor vehicles is attached to the side of the body by laser welding.
- the vehicle body has an upper portion which has an opening adapted to be closed by a roof flag.
- the edge of the aforementioned opening, also called “body side”, and the edge of the roof are shaped so as to form a channel, when they are brought into contact against each other.
- a bead of solder is formed in the bottom of this channel.
- a metal wire is unwound on the fastening zone, this wire is melted using a laser to make the solder which then forms a continuous bead. This technique ensures a continuous connection between the roof and the body with a concentrated and homogeneous heat supply that does not generate deformations.
- An object of the present invention is to provide a method of fixing a roof horn on the body of a vehicle which is an alternative to the aforementioned laser brazing process.
- This object is achieved by means of a method of fixing a roof of a motor vehicle on the body of a motor vehicle, said flag having an upper surface and each side a free edge, said box having a portion upper which has an opening that can be closed by said flag, said opening being delimited by a selvedge, said edge and said free edge being shaped so that when they are put against each other, they form a channel at the level of their contact zone, according to said method, - On each side, said free edge of said flag is attached to said edge of said opening of said box so as to form said channel.
- particles containing at least one metal, in said channel are projected at a very high speed, greater than a critical speed, so as to fill said channel and to obtain a connecting zone which connects said edge and said free edge, whereby said flag is secured to said body.
- said connecting zone is heated at least locally so as to obtain the melting of said metal, which strengthens the bond.
- said heating can be performed by induction, so as to avoid deformation.
- the critical speed is advantageously between 150m / s and 700m / s.
- the particles are advantageously projected at a supersonic speed.
- the metal may be selected from copper, aluminum, zinc, tin and mixtures of two or more of these metals.
- the bond thus has the same physicochemical properties as a traditional solder.
- said channel having a width which represents the distance separating said flag from said box, measured in a direction substantially perpendicular to said free edge, and a length which corresponds to the length of said free edge of said flag, projects said particles containing at least one metal by scanning along said width of said channel and along said length of said channel so as to form said connecting zone.
- said channel having a bottom
- said particles are projected in a direction substantially perpendicular to said bottom of said channel. In this way, the particles do not bounce and form a homogeneous and compact bonding zone, ensuring good fixation.
- the shape of the bottom of the channel is not limited according to the invention as the shape of the channel itself.
- the bottom may be a flat surface or the like.
- the bottom of said channel is formed by a line of contact between said free edge of said flag and said selvedge.
- the present invention also relates to a motor vehicle comprising a body and a roof roof, said roof having an upper surface and on each side a free edge, said body having an upper part which has an opening closed by said roof, said opening being delimited by a selvedge, said selvedge and said free edge being shaped to form a channel, at their contact zone.
- said flag and said box are secured at a connection zone which is formed by projection, at a very high speed, greater than a critical speed, of particles containing at least one metal, in said channel, so as to fill said channel.
- FIG. 1 shows a cross-sectional view of a particular embodiment of the invention.
- FIG. 2 represents a perspective view of the embodiment of FIG. 1.
- the roof 1 of a motor vehicle has an upper surface 11 oriented towards the outside of the vehicle, substantially plane, a lower surface 12, opposite to the upper surface, and on each side, a free edge 14 which extends along the length of the flag.
- This free edge 14 is disposed at a longitudinal band 16 which is slightly curved towards the lower face 12 of the flag 1.
- the body 2 of the vehicle has an upper portion 22 which forms an opening adapted to be closed by the flag 1.
- This opening has a selvedge 24 which is disposed at a substantially curved strip 26 towards the inside of the box 2.
- the free edge 14 and the edge 24 form a channel 13.
- This channel 13 extends along the free edge 14 and has a V-shaped cross section, which is formed by the two curved strips 26 and 16 above.
- the bottom 31 of the channel is formed by a line which represents the contact zone between the free edge 14 of the roof 1 and the edge 24 of the body 2.
- This channel 13 has a maximum width 1, measured substantially at level of the upper surface 11 of the flag 1, and a length L which corresponds to the length of the free edge 14.
- the invention is nevertheless not limited to this type of channel.
- a connection or fastening zone 5 is formed, which corresponds to the interior of the trough 13 and has a substantially flat free surface 51, which is disposed substantially at the same level as the upper surface 11 of the horn 1.
- the nozzle 4 is maintained so that the jet of particles 41 that it produces is substantially perpendicular to the line 31 which forms the bottom of the channel 13. In this way, the ejected particles are deposited correctly in the channel 13, filling it perfectly .
- the depth of the channel 13 is at most 5mm.
- a sweeping is carried out along the width 1 of the channel 13 while remaining substantially perpendicular to the bottom 31. This sweeping is carried out along the entire length L of the channel 13.
- the width 1 of the channel 13 is of the order of 3mm to 4mm while its length L is of the order of 2000mm.
- the flag 1 has a curve that follows the curvature of the body 2, at the front area (front windshield) and rear of the body 2.
- the nozzle 4 follows a path that s' inclines parallel to the aforementioned curve, so that the nozzle distance 41-channel bottom 31, is constant and that the angle ⁇ formed by the bisector of the jet 41 and the bottom 31 is of the order of 90 ° ⁇ 5 °. If the aforementioned angle ⁇ goes too far from the value of 90 °, the projected particles do not form a deposit correct and tend to bounce or ricochet on the side walls and on the bottom 31 of the channel 13.
- a powder of fine particles (diameter between 5 .mu.m and 50 .mu.m) of zinc and tin is sprayed.
- This powder is injected into a nitrogen gas jet, for example, supersonic (nitrogen pressure: 25 bar, nitrogen flow rate 30 m / h), preheated to 300 ° C. maximum.
- the aforementioned nitrogen jet imparts sufficient kinetic energy to the powder to allow adhesion of the powder to the surface of the attachment zone.
- a coherent deposit is obtained which adheres to the surface on which it is deposited by mechanical and chemical bonds, of the metallurgical type.
- the free surface 51 of the connecting zone 5 can then be covered with a sealant-type coating to avoid any problem of corrosion or appearance if necessary.
- the method of the invention can be easily implemented by a robot or can be carried out manually, for example for retouching of bead break, carried out, for example, by laser brazing or deposition (or zone fixation) made according to the method of the invention.
