Definitions
- the invention relates to a method for attaching tabs and / or projections on a thin sheet, in particular on a strip of sheet metal, which is substantially perpendicular to protrude from the base of the thin sheet and have a height, which is higher than the sheet thickness (see, for example, WO 95/05571) and one hereinafter produced sheet and a made of two sheets Rectangular tube for a heat exchanger.
- the invention has for its object to provide a method of to create the type mentioned, the economically too is to realize.
- the inventive method has the advantage that the tabs and / or protrusions not only simple and schettian a thin sheet or thin sheet strips are attached can, but that the tabs and / or projections massive Parts are those without a column or the like. connect to the sheet. As a result, they do not form susceptible to corrosion Put.
- the thin sheet in the region of the tabs and / or projections by means Stamp and die loaded flat over its yield point is, wherein a part of the sheet material in one or several recesses of the die and / or stamp pressed is to attach the tabs as negative molds and / or projections correspond. This can be done in a simple manner while maintaining relatively tight tolerances Attach tabs and / or projections to the sheet.
- a rectangular tube for a Heat exchanger, in particular for an exhaust gas heat exchanger is composed of two U-shaped thin sheet metal shells, with the features of claim 9.
- the rectangular tube 10 shown in FIGS. 1 and 2, which is approximately in is drawn to four times its normal size is to Use in a heat exchanger and in particular a Exhaust heat exchanger determined.
- a tube bundle is formed, which leads to the leadership is determined by exhaust.
- the ends of the tube bundles are each arranged in a gas-tight tube sheet, the Tube sheets together with an outer jacket surrounding the tube bundle a housing for guiding a liquid coolant form.
- This housing is between the two tube sheets with an inlet and an outlet for the liquid coolant Mistake.
- Such an exhaust gas heat exchanger is not in the previously published German patent application P 195 40 683.4 disclosed.
- the rectangular tube 10 is made of two U-shaped thin sheet metal shells 11, 12 composed, which at their webs close together are connected, in particular welded. From the floors the two sheet metal shells 11, 12 protrude to the interior of the Rectangular tube 10 out tabs 13, 14 from, which is about about a quarter to a third of the height of the rectangular tube extend.
- the tabs 13, 14 are each symmetrical in pairs arranged to the longitudinal center of the rectangular tube 10. she run in the flow direction of the gas to be guided V-shaped apart, with their flow direction facing ends keep a distance to each other.
- the paired arranged Tabs 13, 14 are repeated over the length of Rectangular tube 10 at regular intervals.
- the Sheet metal shells 11, 12 offset in such a way to each other, that the tabs 13, 14 of the bottoms of the sheet metal shell 11th and the sheet metal shell 12 offset in the longitudinal direction to each other are arranged.
- the tabs 13, 14 are from the bottoms of the sheet metal shells 11, 12 by means of massive forming and in particular by means of a Extruded molding.
- the thin sheet strips, later transformed into thin sheet half shells 11, 12 become flat between a die and a stamp loaded with pressure such that the yield point of Sheet material is exceeded and a part of the sheet material in slots of a die (or stamp) flows in, which determine the shape of the tabs 13, 14.
- the strips of sheet metal are made by means of a circular surface loaded, which surrounds the two tabs 13, 14. It can, however still other load areas are provided, for example square or rectangular areas or areas, adapted to the contour of the tabs to be formed 13, 14 are.
- the thin sheet metal strips which have a sheet thickness of not more than 1.0 mm, are by means of extrusion to about 70% to about 50% of their original sheet thickness compressed, causing tabs 13, 14 from a height whose height is easily 1.5 times the original one Can be sheet thickness.
- a device is shown schematically by means of that performs the massive forming to form the tabs according to the invention can be.
- the device has a lower part 15, in which a die 16 is arranged.
- the die 16 has a recess 17, in which a sheet-metal strip 18 is inserted is.
- the thin sheet strip 18 is by means of the lower part 15 mounted guides 19 held in the recess 17.
- In the die 16 are slot-shaped recesses 20th provided as negative forms for the tabs to be formed 13, 14 serve.
- a stamp 22 In a lower part 15 under application of a compressive force undeliverable upper part 21, a stamp 22 is held, the between the guides 19 the sheet-metal strip 18 deliverable is, covering the area of the recesses 20 areally.
- the punch 22 has a flat, to the thin sheet 18 parallel punch surface 23, which is the area of the recesses 20 of the die 16 in a sufficiently large area covered.
- the stamp 22 is with its stamp face 23rd pressed into the sheet-metal strip 18 with sufficient force, so that the flow limit of the sheet material exceeded becomes. Part of the sheet material then flows into the recesses 20 and forms the tabs 13, 14, which in Fig. 1 and 2 are shown.
- the thin sheet is in the area the stamp surface 23 to about 70% to about 50% of the original Sheet thickness compressed.
- the impression depth depends on the height of the tabs to be formed. Conveniently, is the penetration depth of the punch surface 23 of the punch 22 limited by a depth stop.
- the recesses 20 may be open slots or have a depth that greater than the desired height of the tabs.
- the high of Lashing is determined by the indentation depth with which the Stamping surface 23 is pressed into the sheet 18. To mention is still that in the extrusion for extrusion usual lubricants are used to the punching time of the tool.
- the extrusion can be carried out in a cold state. If the extrusion in a semi-warm state, for example up to 600 ° C or in the warm state, for example up to 1200 ° C, is carried out, it increases the flowability of the Sheet metal, so that smaller forming forces required are.
- a material for the sheet-metal strips for example a steel with the number 1.4539 proved to be applicable.
- the pairs of tabs 13, 14 intermittently form by the sheet 18 advanced intermittently and the Extrusion process by feeding the punch 22 also is performed in cycles. It is also possible, however similar extrusion by rolling the fine sheet strip perform. It can also be provided that a Median strip in which the tabs 13, 14 by massive forming be formed, constantly extruded and squeezed with it while still the tabs only in regular Distances are formed.
- a die 16 provided with a flat bearing surface, while the recesses 20 corresponding recesses in the punch 22 in Area of the punch surface 23 are provided.
- the recesses 20 in the die 16 has the advantage that the gas-carrying side of a formed from the sheet metal strip 18 Pipe except for the flaps 13, 14 smooth inner walls so that a deposit of solid particles or the like. is avoided.
