Definitions
- the invention relates to the field of manufacturing sheet metal parts. More specifically, the invention relates in particular to a method of manufacturing a part combining stamping and folding steps, and a device for the industrial implementation of such a method.
- Stamping and bending techniques have been mastered and widely used for many years. The pieces produced using one of these techniques, or a combination of these techniques, are diverse and varied. However, for certain parts, it is currently difficult, if not impossible, to use an industrial folding technique when the stamped part has a particular design.
- a sheet is deformed using a movable matrix relative to a fixed counter-die, the sheet being interposed between the die and the counter-die.
- the stamping step is followed by a cutting step carried out using a cutting punch moved transversely relative to the direction of movement of the die. For this, it is necessary to exert a counter-support against the force of the cutting punch, which is done by maintaining the stamped part using a new matrix coming into contact with the face of the part corresponding to the stamping counter-die.
- a cutting die extends in a plane parallel to the drawing direction.
- the stamped part may have a relief on its face corresponding to the counter-matrix, this in the vicinity of one of the edges of the part, possibly that corresponding to the cut made as mentioned above.
- a folding requires the establishment of a folding matrix and, when the folding must be carried out on the relief side, the use of this matrix proves to be impossible due to the proximity of the relief relative to the fold. to achieve.
- Such a relief indeed appears in undercut, preventing the establishment of a conventional folding matrix. This type of problem is encountered in the field of motor vehicles, and more specifically with regard to the front cradles.
- such cradles are produced by assembling two stamped sheet metal shells.
- One of the functions of these cradles is to withstand the forces generated by the engine torque during acceleration or deceleration phases of the vehicle.
- a technique now widely used consists in fixing the engine to the cradle by a “pendulum” type mounting, this by means of a connecting rod connecting the engine to the cradle.
- This method of attachment creates an opening in the front part of the cradle.
- the two shells each have a boss, the two bosses together delimiting a space in which is inserted the fixing rod so that it is supported on each of the bosses.
- the bosses 1 1 1 and 121 define between them a location in which a connecting rod 5 for taking up the engine torque is inscribed. According to this solution, it is therefore necessary to manufacture the reinforcement pieces, then fix them on the cradles by a welding operation, which tends to increase the price and the weight of the cradle.
- the invention particularly aims to overcome the drawbacks of the prior art.
- the invention aims to propose a technique for manufacturing stamped sheet metal parts which makes it possible to carry out a step of folding an edge in the immediate vicinity of a relief, including when this relief does not allow the establishment of a folding matrix according to conventional techniques.
- the invention also aims to provide such a technique which can be implemented easily, with a simple design device.
- the invention also aims to provide such a technique which can advantageously be applied in the field of the automobile industry, in particular for the manufacture of engine cradles.
- Another object of the invention is to provide such a cradle which is less expensive and lighter than those of the prior art, while having an endurance comparable to these.
- a sheet metal part comprising at least one base surface having a boss in the vicinity of the at least one of its edges, called the proximal edge, said boss being formed on one face, said internal face, of said base surface, characterized in that it comprises: - at least one stamping step during which is made said boss; at least one step of folding said proximal edge towards said boss, until said proximal edge extends substantially parallel to said internal surface, said folding step being carried out by exerting at least in the vicinity of said proximal edge, a counter-pressing force on the face opposite to said internal surface of said base surface.
- the invention provides a manufacturing technique for folding an edge on a sheet metal part whose structure does not allow the establishment of a folding die according to the traditional technique.
- stampers have always given up making such a fold, not being able precisely to use conventionally the folding dies.
- the invention therefore has a wide field of applications, whether for carrying out reinforcing folds or finishing folds.
- said folding step is continued until said proximal edge comes to bear against said internal surface. This optimizes the reinforcement provided by the folded edge, the mechanical strength obtained for the edge of the opening being of the same order as with a reinforcement piece according to the prior art.
- the method comprises at least one step of cutting a recess in a surface of said part forming a non-zero angle with said base surface and being carried out during said stamping step, said recess being made in the vicinity of said boss.
- the invention also relates to a device for implementing the manufacturing process as described above, comprising: - means for exerting an abutment force at least in the vicinity of said proximal edge; - Folding means of said proximal edge towards said boss, until said proximal edge extends against said internal surface.
- the invention also relates to a sheet metal part comprising at least one base surface having a boss in the vicinity of at least one of its edges, known as the proximal edge, said boss being formed on one face, said internal face, of said surface.
- said part being obtained by a process comprising: - at least one stamping step during which said boss is produced; at least one step of folding said proximal edge towards said boss, until said proximal edge extends substantially parallel to said internal surface, said folding step being carried out by exerting at least in the vicinity of said proximal edge, a counter-pressing force on the face opposite to said internal surface of said base surface.
- the invention also relates to a cradle of a motor vehicle, characterized in that it includes at least one shell comprising at least one base surface having a boss in the vicinity of at least one of its edges, called the proximal edge, said boss being formed on one face, called the internal face, of said base surface, said shell being obtained by a process comprising: - at least one stamping step during which said boss is produced; - at least one step of folding said proximal edge towards said boss, until said proximal edge extends substantially parallel to said internal surface, said folding step being carried out by exerting at least in the vicinity of said proximal edge, a counter-pressing force on the face opposite to said internal surface of said base surface.
- said proximal edge is one of the edges of a window intended to form a passage for a link for taking up a motor torque.
- the cradle preferably comprises two shells assembled together and each having a boss intended to form a bearing surface for one end of said rod, the lower and upper edges of said window being both folded substantially parallel to the surface base of the shell in the vicinity of which they extend.
- At least a portion of a rear edge of said shell, or of one of said shells defines a bearing surface capable of coming into contact, during an impact received by said vehicle, with a essentially vertical wall of the body of said vehicle in the vicinity of which said cradle is mounted.
- the cradle exhibits improved impact behavior, in particular in the event of a frontal impact from a high-speed vehicle.
- the cradle according to the invention moves back in the event of a significant frontal impact and comes to bear, with a plane support, on the body of the vehicle to transmit to it the forces collected.
- said shell has a flange defining an assembly plane with another shell, said one or more portions each corresponding to at least one protrusion formed in said flange. In this way, this outgrowth can be achieved using a stamping die of the corresponding shell.
- the bearing surface capable of coming into contact with the body during an impact can therefore be obtained at lower cost, this without adding material or a part which would cause an increase in weight.
- said protuberance is formed by a deformation of said rear edge so that said one or more portions have an essentially U shape.
- said U shape of said one or more portions preferably comprises said U shape of said one or more protrusions comprises two uprights interconnected by an essentially flat upper edge. It is thus possible to increase the bearing surface capable of coming into contact with the body, this as much as necessary depending on the characteristics of impact behavior that it is desired to obtain.
- said protuberance (s) extend between said portion (s) and said base surface of said shell so that said U and said base surface are connected by at least one line substantially inscribing in the plane of said base surface.
- said one or more protrusions have a progressive section which widens in the direction of said base surface.
- said base surface and said assembly flange are connected by a connecting wall, said one or more protrusions being bordered by two curved surfaces which connect said protuberance to said connecting wall. This also contributes to the gradual absorption of a possible shock.
- the cradle comprises a portion defining a bearing surface in the vicinity of each of the ends of said rear edge.
- the cradle thus exhibits improved impact behavior, whatever the direction of the impact or almost.
- the invention also relates to a cradle shell, comprising at least one base surface having a boss in the vicinity of at least one of its edges, called the proximal edge, said boss being formed on one side, said inner side, of said base surface, characterized in that said shell is obtained by a process comprising: - at least one stamping step during which said boss is produced; - At least one step of folding said proximal edge towards said boss, until said proximal edge extends substantially parallel to said internal surface, said folding step being carried out by exerting at least in the vicinity of said proximal edge, a force against pressing on the face opposite to said internal surface of said base surface.
- the invention also relates to a vehicle equipped with at least one cradle including at least one shell comprising at least one base surface having a boss in the vicinity of at least one of its edges, called the proximal edge, said boss being formed on a face, called internal face, of said base surface, characterized in that said shell is obtained by a process comprising: - at least one stamping step during which said boss is made; at least one step of folding said proximal edge towards said boss, until said proximal edge extends substantially parallel to said internal surface, said folding step is carried out by exerting at least in the vicinity of said proximal edge, a counter-pressing force on the face opposite to said internal surface of said base surface.

- FIGS. 4a and 4b illustrate a cradle according to the invention produced using a method such as that which will be described later.
- a cradle otherwise called “mini cradle” by those skilled in the art, is secured to the body in the rear part and, in the front part, to a shock absorber 3 or "add-on" fixed on the plates 14 of the cradle.
- a cradle is coupled to lower arms 4 wheel supports or carrying wheel support means 41 (represented symbolically), an anti-roll bar 42 connecting these arms and being held on the cradle.
- this cradle consists of two half-shells 11, 12 each having a boss, respectively 1 1 1, 121, defining between them a location in which is inscribed a connecting rod 5 for taking up the engine torque.
- a link 5 is shown in Figure 4b.
- a second link 51 for taking up the engine torque is generally coupled to the cradle.
- the upper shell 1 1 comprises a base surface 1 12 on the internal surface 1 121 of which is formed the boss 1 1 1.
- such an upper shell 1 1 has a connecting wall 1 13 extending from the base surface 1 12 and connecting the latter to an assembly flange 1 14 defining an assembly plane with the lower shell 12.
- the connecting wall 1 13 has an opening 13 produced in the vicinity of the boss 1 1 1 obtained on the internal face of the upper shell, during the stamping of the latter, and of the boss 121 which the lower shell 12 has.
- This opening has an upper edge, said proximal edge 131, folded so as to create a double thickness with the base surface 1 12 of the upper shell.
- the lower edge 132 of the window 13 is also folded so as to extend parallel to the base surface 122 of the lower shell 12. According to the present embodiment of the invention illustrated in FIG. 5, the folding of the proximal edge 131 is therefore provided so that it extends parallel to the internal surface 1 121 of the shell.
- Folding can also be carried out, according to another possible embodiment, so that the proximal edge comes to bear against the internal surface of the shell.
- the process for manufacturing a sheet metal part, and in particular a cradle shell, such as that which has just been described, as well as the device for implementing such a process will now be explained in reference to FIGS. 6 to 8.
- An initial step in the process for manufacturing an upper shell of a cradle according to the invention consists in stamping a sheet of sheet metal in a manner known per se.
- the opening 13 is then made in the connecting wall 1 13 of the shell according to the technique illustrated in FIG. 8.
- a cutting die 80 is introduced into the shell 1 1, this die having a recess 801, then a punching tool 81 comes to cut the wall 1 13 by penetrating the recess 801 of the die 80, in the manner of a cookie cutter.
- the proximal edge 131 of the opening 13 in the vicinity of the boss 1 1 1 is folded so as to extend parallel to the internal surface 1 121 of the shell. This step of the method is carried out using a device such as that appearing in FIGS. 6 and 7.
- this step of the method is carried out by introducing a partial matrix 60 inside the shell then by introducing through the opening obtained thanks to the punching tool, a folding tool 61.
- This folding tool 61 comprises a part active folding 61 1 which causes the folding of the proximal edge 131 as the tool is introduced into the opening.
- the folding tool further comprises a counter-support element 612 intended to come to bear on the external surface of the base surface 1 12 (as opposed to the internal surface 1121). As clearly shown in Figure 6, the counter-support element
- one of the shells of the cradle has a rear edge, a portion of which defines a bearing surface capable of coming into contact, during an impact, with an essentially vertical wall of the body.
- such a portion corresponds to a protrusion formed in the vicinity of each of the ends of the rear edge of the upper shell 11 of the cradle.
- Figure 9 shows that the rear edge of the upper shell 1 1 has at each of its ends a projection 91 formed in a flange forming 1141 an assembly plane with the lower shell.
- each of the protrusions 91 has a section having a shape essentially in a U, this U being in this case inverted and having a flat upper edge 91 1.
- this protuberance 91 extends so as to present a upper plane 912 which is inscribed in the plane of the base surface of the upper shell 1 1.
- each protuberance 91 has a section which gradually widens towards the base surface, this having lateral walls curved 913 in the direction of the connecting flange 1131 of the shell which extends between the base surface 11 and the assembly flange 1141.
