Definitions
- the invention relates to an exhaust manifold according to the features in the preamble of claim 1.
- exhaust manifolds for motor vehicle engines are predominantly made of cast steel. This is inevitably associated with a high weight, which then also leads to a high overall weight of the motor vehicles. In addition, the heat capacity of thick-walled exhaust manifolds is high.
- exhaust manifolds are also part of the prior art, which are formed by stamping, bending and welding sheet metal. These are so-called half-shell manifolds. Each shell requires a blank stamped from a sheet of steel, which is then deformed by half-shaping the inflow channels and the outflow channel. The two shells will then placed with their edges on top of each other to form the manifold housing and then welded along the edges. Ultimately, a head flange is attached on the inflow side and a pipe flange on the outflow side by welding.
- the top flange is welded to the multi-channel inflow side and the pipe flange to the single-channel outflow side.
- the head flange is used to fasten the exhaust manifold to the engine block, while the pipe flange is provided for connecting the exhaust pipe which transmits the exhaust gases.
- the invention has for its object to provide an exhaust manifold which is formed by punching, bending and welding sheet metal, but which requires less production effort and improved exhaust gas routing.
- the essential aspect of the invention is that the housing of the exhaust manifold is now made entirely from a single board. For this is to provide only one follow-on tool, which first stamps the board out of a steel sheet and then forms this board into the manifold housing.
- the manifold housing has a cross section resulting from the bending geometry both with respect to the inflow channels and the outflow channel.
- the guide plates which are made in a parallel tool depending on the number of inflow channels, are inserted into the manifold housing and welded to it.
- the particular advantage of the invention lies in the construction, which is significantly less expensive than the known half-shell manifold, with a considerably shorter weld seam length. Exhaust gas routing can now also be specifically optimized. As a result of the more cost-effective design, the weight of the exhaust manifold has also been reduced while using less material. However, its strength is greater because the weld seam length has been reduced.
- the inflow channels and the outflow channel can have a rectangular cross section. Cross sections that differ from one another are also conceivable. Furthermore, the inflow channels and / or the outflow channel can have a U-shaped cross section.
- baffles are bent in a V-shape, with the majority of their longitudinal edges inserted in the carrier slots of the circuit board bent to the manifold housing and welded along the carrier slots.
- the V-shape of the guide plates enables an optimal flow design of the inflow channels with a corresponding transition into the outflow channel. Welding work can be done easily from the outside and involves no special effort.
- the exhaust manifold 1 in FIGS. 1, 3 and 4 denotes an exhaust manifold for a six-cylinder engine.
- the exhaust manifold 1 comprises a manifold housing 2, a head flange 3 on the multi-channel inflow side and a pipe flange 4 extending at right angles to the head flange 3 on the single-channel Outflow side.
- the exhaust manifold 1 has baffles 5, 6, 7 which, together with the manifold housing 2, form three inflow channels 8, 9, 10 and one outflow channel 11.
- the inflow channels 8, 9, 10 are aligned with adapted cutouts 12, 13, 14 in the head flange 3, while the outflow channel 11 is aligned with a cutout 15 in the pipe flange 4.
- top flange 3 there are bores 69 for fixing the exhaust manifold 1 to an engine block.
- the circuit board 16 has a central web wall 20 consisting of three web sections 17, 18, 19 and leg walls 21, 22 or 23, 24 or 25, 26 lying to the side of the web sections 17, 18, 19.
- the leg walls 21-24 are provided with carrier slots 31-38 extending from the leg edges 27-30.
- leg walls 21-26 are then folded over the bending lines 39, 40 at an angle ⁇ of 90 ° to the web sections 17, 18, 19.
- the longitudinal edges 41 are rounded ( Figure 4).
- leg walls 23 and 24 together with the web section 18 are bent so far about the bending line 42 between the two web sections 17, 18 that the leg edges 43, 44 of the leg walls 23, 24 touch the leg edges 45, 46 of the leg walls 21, 22 bump.
- leg walls 25, 26 and the web section 19 are also bent so far about the bending line 47 between the two web sections 18, 19 that that the leg edges 48, 49 of the leg walls 25, 26 abut the leg edges 50, 51 of the leg walls 23, 24.
- circular cutouts 52 are provided in the intersections of the bending line 39 with the leg edges 43, 45 or the leg edges 48, 50 and in the intersections of the bending line 40 with the leg edges 44, 46 and 49, 51.
- the manifold housing 2 now already has the configuration according to FIGS. 1, 3 and 4.
- the guide plate 5 is curved in an arc and is welded to the curved leg edges 53 of the leg walls 21, 22, which connect the leg edges 27, 28 of the leg walls 21, 22 to the U-shaped end edge 54.
- the two other guide plates 6, 7 shown stretched in FIGS. 5 and 6 each consist of three surface sections 55, 56, 57 and 58, 59, 60, the middle surface sections 56, 59 being narrower than the outer surface sections 55, 57 and 58, 60 are dimensioned.
- the width B of the outer surface sections 55, 57 and 58, 60 corresponds to the outer width B1 of the manifold housing 2, while the width B2 of the middle surface sections 56, 59 corresponds to the inner width B3 of the manifold housing 2 (FIGS. 1 and 4).
- the guide plates 6, 7 are curved in accordance with the carrier slots 31, 33 or 32, 34 or 35, 37 or 36, 38 in the leg walls 21-24 and bent in a V-shape and subsequently with their edges 61, 62 or 63, 64 or 65, 66 or 67, 68 of the outer surface sections 55, 57, 58, 60 inserted into the carrier slots 31-38.
- the V-shaped middle surface sections 56, 59 then only form spacer elements between the leg walls 21 and 22 or 23 and 24.
- edges 61, 62 or 63, 64 or 65, 66 or 67, 68 of the wider surface sections 55, 57, 58, 60 of the guide plates 6, 7 are now welded from the outside into the carrier slots 31-38.

Abstract
Description
Die Erfindung betrifft einen Abgaskrümmer gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to an exhaust manifold according to the features in the preamble of
Bislang werden Abgaskrümmer für Kraftfahrzeugmotoren in der überwiegenden Mehrzahl aus Stahlguß gefertigt. Hiermit ist zwangsläufig ein hohes Gewicht verbunden, was dann ebenso folgerichtig zu einem hohen Gesamtgewicht der Kraftfahrzeuge führt. Außerdem ist die Wärmekapazität von dickwandigen Abgaskrümmern hoch.So far, exhaust manifolds for motor vehicle engines are predominantly made of cast steel. This is inevitably associated with a high weight, which then also leads to a high overall weight of the motor vehicles. In addition, the heat capacity of thick-walled exhaust manifolds is high.
Es zählen aber auch schon Abgaskrümmer zum Stand der Technik, die durch Stanzen, Biegen und Schweißen von Blechen gebildet sind. Hierbei handelt es sich um sogenannte Halbschalenkrümmer. Jede Schale setzt eine aus einem Stahlblech gestanzte Platine voraus, die anschließend unter hälftigem Ausprägen der Einströmkanäle sowie des Ausströmkanals verformt werden. Die beiden Schalen werden dann zur Bildung des Krümmergehäuses mit ihren Kanten aufeinander gelegt und anschließend entlang der Kanten verschweißt. Letztlich werden einströmseitig ein Kopfflansch und ausströmseitig ein Rohrflansch durch Schweißen befestigt.However, exhaust manifolds are also part of the prior art, which are formed by stamping, bending and welding sheet metal. These are so-called half-shell manifolds. Each shell requires a blank stamped from a sheet of steel, which is then deformed by half-shaping the inflow channels and the outflow channel. The two shells will then placed with their edges on top of each other to form the manifold housing and then welded along the edges. Ultimately, a head flange is attached on the inflow side and a pipe flange on the outflow side by welding.
Es liegt auf der Hand, daß die Fertigung eines solchen Abgaskrümmers mit einem relativ hohen Aufwand verbunden ist. Jede Schale erfordert ein eigenes Stanz- und Prägewerkzeug, wobei die bogenförmig gekrümmten Wände der Einströmkanäle und des dazu sich rechtwinklig erstreckenden Ausströmkanals einen zusätzlichen Aufwand bedeuten. Die Schweißnähte sind vergleichsweise lang und insbesondere zwischen den beiden außenliegenden Einströmkanälen kompliziert herzustellen.It is obvious that the production of such an exhaust manifold is associated with a relatively high outlay. Each shell requires its own punching and embossing tool, with the curved walls of the inflow channels and the outflow channel extending at right angles to this requiring additional effort. The weld seams are comparatively long and, in particular, complicated to produce between the two external inflow channels.
Nach dem Schweißen werden an die mehrkanalige Einströmseite der Kopfflansch und an die einkanalige Ausströmseite der Rohrflansch geschweißt. Der Kopfflansch dient zur Befestigung des Abgaskrümmers am Motorblock, während der Rohrflansch zum Anschluß des die Abgase weiterleitenden Auspuffrohrs vorgesehen ist.After welding, the top flange is welded to the multi-channel inflow side and the pipe flange to the single-channel outflow side. The head flange is used to fasten the exhaust manifold to the engine block, while the pipe flange is provided for connecting the exhaust pipe which transmits the exhaust gases.
Der Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zugrunde, einen Abgaskrümmer zu schaffen, der durch Stanzen, Biegen und Schweißen von Blechen gebildet ist, jedoch einen geringeren Herstellungsaufwand bei verbesserter Abgasführung benötigt.Based on the prior art, the invention has for its object to provide an exhaust manifold which is formed by punching, bending and welding sheet metal, but which requires less production effort and improved exhaust gas routing.
Die Lösung dieser Aufgabe besteht nach der Erfindung in den im kennzeichnenden Teil des Anspruchs 1 aufgeführten Merkmalen.This object is achieved according to the invention in the features listed in the characterizing part of
Der wesentliche Gesichtspunkt der Erfindung besteht darin, daß das Gehäuse des Abgaskrümmers nunmehr komplett aus einer einzigen Platine hergestellt wird. Hierfür ist nur ein Folgewerkzeug bereitzustellen, welches zunächst die Platine aus einem Stahlblech stanzt und diese Platine dann zum Krümmergehäuse umformt. Das Krümmergehäuse weist sowohl bezüglich der Einströmkänale als auch des Ausströmkanals einen aus der Biegegeometrie resultierenden Querschnitt auf.The essential aspect of the invention is that the housing of the exhaust manifold is now made entirely from a single board. For this is to provide only one follow-on tool, which first stamps the board out of a steel sheet and then forms this board into the manifold housing. The manifold housing has a cross section resulting from the bending geometry both with respect to the inflow channels and the outflow channel.
Nach dem Biegen des Krümmergehäuses werden die in Abhängigkeit von der Anzahl der Einströmkanäle in einem parallelen Werkzeug gefertigten Leitbleche in das Krümmergehäuse eingesetzt und mit diesem verschweißt.After the manifold housing has been bent, the guide plates, which are made in a parallel tool depending on the number of inflow channels, are inserted into the manifold housing and welded to it.
Der besondere Vorteil der Erfindung liegt in der im Vergleich zu dem bekannten Halbschalenkrümmer deutlich kostengünstigeren Bauweise bei erheblich geringerer Schweißnahtlänge. Auch kann jetzt die Abgasführung gezielt optimiert werden. Infolge der kostengünstigeren Bauweise ist bei vermindertem Materialeinsatz auch das Gewicht des Abgaskrümmers reduziert worden. Seine Festigkeit ist dennoch größer, da die Schweißnahtlänge verringert worden ist.The particular advantage of the invention lies in the construction, which is significantly less expensive than the known half-shell manifold, with a considerably shorter weld seam length. Exhaust gas routing can now also be specifically optimized. As a result of the more cost-effective design, the weight of the exhaust manifold has also been reduced while using less material. However, its strength is greater because the weld seam length has been reduced.
Nach Anspruch 2 können die Einströmkanäle und der Ausströmkanal einen rechteckigen Querschnitt aufweisen. Denkbar sind auch voneinander abweichende Querschnitte. Ferner können die Einströmkanäle und/oder der Ausströmkanal einen U-förmigen Querschnitt haben.According to
Eine besonders vorteilhafte Ausführungsform der Erfindung wird in den Merkmalen des Anspruchs 3 erblickt. Danach sind einige Leitbleche V-förmig gebogen, mit dem überwiegenden Teil ihrer Längskanten in Trägerschlitze der zum Krümmergehäuse gebogenen Platine eingesetzt und entlang der Trägerschlitze verschweißt.A particularly advantageous embodiment of the invention is seen in the features of
Die V-Form der Leitbleche ermöglicht bei entsprechender Krümmung der Seitenwände eine optimale strömungstechnische Gestaltung der Einströmkanäle mit einem entsprechenden Übergang in den Ausströmkanal. Schweißarbeiten sind problemlos von außen durchzuführen und mit keinem besonderen Aufwand verbunden.With a corresponding curvature of the side walls, the V-shape of the guide plates enables an optimal flow design of the inflow channels with a corresponding transition into the outflow channel. Welding work can be done easily from the outside and involves no special effort.

Daraufhin werden die Schenkelwände 23 und 24 zusammen mit dem Stegabschnitt 18 um die zwischen den beiden Stegabschnitten 17, 18 liegende Biegelinie 42 so weit abgekantet, daß die Schenkelränder 43, 44 der Schenkelwände 23, 24 an die Schenkelränder 45, 46 der Schenkelwände 21, 22 stoßen.Thereupon, the
Parallel hierzu oder in einem voraufgehenden bzw. nachfolgenden Biegevorgang werden auch die Schenkelwände 25, 26 und der Stegabschnitt 19 um die zwischen den beiden Stegabschnitten 18, 19 liegende Biegelinie 47 so weit abgekantet, daß die Schenkelränder 48, 49 der Schenkelwände 25, 26 stirnseitig an die Schenkelränder 50, 51 der Schenkelwände 23, 24 stoßen.Parallel to this or in a preceding or subsequent bending process, the
Um einen einwandfreien Biegevorgang zu gewährleisten, sind in den Schnittpunkten der Biegelinie 39 mit den Schenkelrändern 43, 45 bzw. den Schenkelrändern 48, 50 und in den Schnittpunkten der Biegelinie 40 mit den Schenkelrändern 44, 46 bzw. 49, 51 kreisrunde Aussparungen 52 vorgesehen.In order to ensure a perfect bending process,
Das Krümmergehäuse 2 hat nunmehr bereits die Konfiguration gemäß den Figuren 1, 3 und 4.The
Unabhängig vom Stanzen und Biegen des Krümmergehäuses 2 werden die drei Leitbleche 5, 6 und 7 erzeugt. Das Leitblech 5 ist bogenförmig gekrümmt und wird mit den gekrümmten Schenkelrändern 53 der Schenkelwände 21, 22 verschweißt, welche die Schenkelränder 27, 28 der Schenkelwände 21, 22 mit dem U-förmigen Stirnrand 54 verbinden.Regardless of the punching and bending of the
Die beiden anderen in den Figuren 5 und 6 gestreckt veranschaulichten Leitbleche 6, 7 bestehen jeweils aus drei Flächenabschnitten 55, 56, 57 bzw. 58, 59, 60, wobei die mittleren Flächenabschnitte 56, 59 schmaler als die äußeren Flächenabschnitte 55, 57 bzw. 58, 60 bemessen sind. Die Breite B der äußeren Flächenabschnitte 55, 57 bzw. 58, 60 entspricht der äußeren Breite B1 des Krümmergehäuses 2, während die Breite B2 der mittleren Flächenabschnitte 56, 59 der inneren Breite B3 des Krümmergehäuses 2 entspricht (Figuren 1 und 4).The two
