- the band sections can also have a linear connection edge that is oblique with respect the longitudinal direction of the exhaust gas housing part to be manufactured runs.
- An advantageous rolling device for producing a board provides at least two profiled pressure rollers, their axial distance from one another is preferably adjustable.
- the pressure rollers are preferably interchangeable.
- the pressure rollers can also use interchangeable profiled roller cylinders or roll cylinder rings, which preferably a different rolled profile and / or a different one Have cylinder diameter.
- the pressure rollers or the roller cylinders or roller cylinder rings can not only be circular in cross section, but also at least partially have oval shape to different Form thicknesses in the transverse direction of a board.
- a method for manufacturing an exhaust housing part provides in particular a prefabrication of a one-piece part reinforced board by rolling a strip material.
- the board is made of a strip material as a one-piece, profiled sheet metal part of different thickness with at least one band section of smaller thickness and at least prefabricated a section of tape of greater thickness that the manufactured exhaust gas housing part (half shell, funnel, cylinder locally) at least in a wall area.
- the one-piece, profiled sheet metal part is, for example in an embossing tool consisting at least of stamp and Stamped in order to in particular an (upper or lower) Form half-shell. It is understood that stamp and / or die of the embossing tool for the partially thicker one
- the circuit board is configured or recessed accordingly.
- the aforementioned board can not only one stamping process, but as a prefabricated semi-finished product in a corresponding Tool also undergo a winding process to exhaust housing parts in a wrap or jacket design with partial To produce jacket reinforcement.
- the wrapped shells, Pipes or jacket are preferably with a longitudinal weld provided, in particular with a laser weld.
- the invention advantageously makes exhaust gas housing parts, in particular embossed half-shells of exhaust silencers and Exhaust gas catalysts, can be designed in a lightweight design, without loss to have to accept strength or dimensional stability.
- the exhaust housing parts are only in those places where special demands are placed on strength, in the wall thickness by increasing the profile accordingly partially reinforced. In all other places is the wall thickness the board or the individual sheets low, so that with the overall wall reduction there a weight reduction and save material.
- According to the state of the Technology would have a single-wall design of an exhaust housing part there, too, a greater thickness not required per se a single sheet or a board designed or on Double wall construction can be transferred. Because the board not even from several assembled, welded together Individual parts, but is made in one piece, also do not have to put together individual parts and with each other are welded, which simplifies the manufacturing process.
- the invention is particularly suitable for bowl-shaped Parts for exhaust silencers and catalytic converters, however also for other parts where different Wall thickness while respecting the requirements regarding structure-borne noise, Heat shielding and durability a weight reduction is possible. So it is preferably half-shell-shaped Parts of an exhaust system partially on selected Places to maintain function, strength and heat shielding strengthened. The boards will be in front of you Embossing or winding into the final shape from cut sheets rolled. The function of the manufactured exhaust housing part improved.
- an exhaust gas housing part in the form of an exhaust silencer 2 for an exhaust system of a motor vehicle as well as boards required for production 1 in different Design variants with manufacturing tools shown.
- the exhaust muffler 2 in half-shell construction has one upper and a lower half-shell 6, in their horizontal Parting plane by means of a circumferential fold or an edge weld 20 are firmly connected.
- the circuit board 1 is a one-piece, profiled Rolled sheet metal part of different thickness with at least one Band section 10 of smaller thickness S2 and at least one Band section 11 of greater thickness S1, which is the manufactured exhaust housing part (Half-shell, funnel, cylinder or nozzle) at least locally reinforced in a wall area.
- the manufactured exhaust housing part Half-shell, funnel, cylinder or nozzle
- the band section 11 of greater thickness can be at least one raised one be narrow longitudinal web or at least according to Figure 6 additionally include a raised narrow longitudinal web 12.
- the board 1 or the rolled sheet metal part can be at least on one Have a rolled-in pattern 13 according to FIG. 8, which, for example, longitudinal and / or horizontal stripes, checks or can be circular or square knobs.
