Definitions
- the invention relates to a silencer casing or exhaust line catalyst for a motor vehicle, defined by a tube designed by winding and welding a metal strip, this tube having at least one of its ends a deformation by flow spinning. for the definition of an exhaust gas inlet and / or outlet cone.
- the invention also relates to its manufacturing process.
- the present invention will find its application in the field of envelopes for mufflers or catalytic converter used in the composition of an exhaust line for a motor vehicle.
- this envelope results, for example, from the winding of a sheet blank on itself.
- the edges of the blank are then assembled by crimping to form the envelope at the ends of which are fitted inlet and outlet cones.
- the flow-forming solution consists in deforming, by means of suitable tools, the ends of such a tube so as to conform inlet and outlet cones opening out through a section of tube of reduced diameter. Note that the tube is itself obtained by forming and welding, starting from a plate or a metal strip.
- this metal strip of width corresponding to the perimeter of the tube passes through a profiling unit ensuring the winding of this strip on itself so as to present, edge to edge, its lateral sides before their welding takes place. Consequently, the tube leaving continuously from this forming line is cut into regular sections which will then be oriented towards the other stations for making the silencer or the catalytic converter, in particular towards the flow-forming stations for the definition of the cones. entry and exit.
- the flow turning solution leads to products with a lower cost price, since they require less manufacturing time, but in addition to increased resistance.
- the tube results from a spiral winding and welding process of a metal strip.
- the weld line itself forms a spiral around the tube so that it cannot extend parallel to the axis of the latter, in particular in the portions intended to undergo deformation, more particularly by filming.
- the invention relates to a silencer casing or exhaust line catalyst for a motor vehicle, defined by a tube designed by winding and welding a metal strip, this tube having at least one of its ends. a deformation by flow-forming for the definition of an inlet and / or outlet cone of the exhaust gases, characterized in that at least in the portion or portions of the tube shaped by flow-turning, the weld line, ensuring the closure of the wound metal strip forms an angle with respect to the axis of said tube.
- the invention also relates to a method of manufacturing such a silencer casing or exhaust line catalyst for a motor vehicle comprising an inlet and / or outlet cone opening out through a section of tube of smaller diameter. , characterized by the fact that:
- a tube is made by spiral winding and welding of a metal strip; - For the design of the inlet and / or outlet cone of said envelope, one and / or the other end of the tube is deformed by flow-turning.
- Figure 1 is a schematic representation of a silencer casing or catalytic converter according to the invention
- FIG. 2 is a schematic representation of the tube, before flow turning, intended to constitute this envelope.
- the present invention relates to a casing 1 of a silencer or exhaust line catalyst for a motor vehicle.
- This envelope 1 usually ends at its ends 2, 3 with an inlet cone 4 and an outlet cone 5. These open out through a section of tube 6, 7 of smaller diameter and by the through which the silencer or the catalyst integrates into said exhaust line.
- this envelope 1 is designed from a metal tube 8 at the ends 9, 10 of which deformations have been carried out by flow spinning to conform the inlet 4 and outlet 5 cones.
- This tube 8 and the flow forming tool 11 are illustrated diagrammatically in FIG. 2.
- the tube 8 results from the winding and welding of a metal strip 12, knowing that in the portions 13, 14 of this tube 8 shaped by flow-turning the weld line 15 ensuring the closure of this strip wound metal 12 forms an angle 16 with respect to the axis 17 of said tube 8.
- the latter results from the spiral winding of said metal strip 12 so that the weld line 15 itself describes a spiral whose tangent is at no point parallel to this axis 17 of the tube 8, in particular in the portions 13, 14 intended to be deformed by flow spinning.
