Definitions
- the present invention relates to a progressive tool for Production of a structured metal foil with at least two structures, one of the two structures at least partially the other structure superimposed, the progressive tool from one Tool upper part and a lower tool part. Furthermore concerns the present invention a method for producing a structured metal foil, in particular as a catalyst carrier body serves.
- Such structured metal foils are folded into long ribbons and wound into catalyst honeycomb bodies with a special geometry.
- the Honeycomb bodies have a large number of honeycomb cells, on their Wall of the catalytic process on a catalytically active Coating expires. In this way, catalysts are built primarily used in internal combustion engines to get through increasing mobility causes pollution of the environment to reduce.
- metal is there because of its advantageous physical-technical properties such as high mechanical and thermal stability, an ideal carrier material for the catalytically active Coating.
- a disadvantage of this prior art is that when using intermeshing rollers with increasingly smaller material thicknesses of Sheet metal and increasingly smaller profile depths of the wave structure comes to formation of burrs when introducing the secondary structure, which is very disruptive to the galvanic deposition of the catalytically active Coating affects, so that the conversion ability of the catalyst reduced rather than increased.
- the object of the present invention is therefore a device and a Processes to indicate that the manufacture is very thin, structured Metal foils with a large surface while observing high ones Quality standards allowed.
- the progressive tool at least three, in particular spatially separate, work areas has, namely a punching area for removing film material at certain positions on the metal foil, a primary one Shaping area for the introduction of the, preferably corrugated, Primary structure in the metal foil and a secondary Shaping area for the introduction of the, preferably corrugated, Secondary structure in the metal foil, preferably in the primary structure of the Metal foil.
- the progressive composite tool With the aid of the progressive composite tool according to the invention, it is possible to extremely thin, structured metal strips in one processing step a single tool, while maintaining the lowest Manufacturing tolerances.
- the metal strips are manufactured more economical than with that described in the prior art Device because the metal foil on a machine with a tool is processed because progressive dies with one machining step can punch and shape.
- a Progressive tool reduces the formation of burrs on the Workpieces so that a complete catalytically effective surface can be deposited on the metal carrier.
- the removal of foil material at certain positions in the Punching area ensures that a made from the material Catalyst has a significantly longer service life in everyday use because due to the removal of material tensions within the metal foil degraded, and notch effects at the transition areas between primary and secondary structure can be avoided. It is sometimes desirable that metal foil at each transition area between the primary and secondary structure is removed. There are also Areas of application in which the film material only on selected Places, for example at selected transitions between primary and Secondary structure is removed.
- a drive for the progressive die For example, a press consisting of a press bed and one driven by an eccentric disc movable bear, with the bear engaging the tool top stands. However, it does not necessarily have to be an eccentric drive be provided. For example, the operation of the Progressive tool with a hydraulic drive possible.
- the punching area in the feed direction of the metal foil before the primary and the secondary shaping area is arranged. Not this one necessary but advantageous arrangement of the punching area leads to that the foil material to be removed from the still smooth metal foil can be punched out.
- the stamping area can be significantly lower manufacturing tolerances are observed as if the punching area, for example the Shaping areas would be downstream.
- additional work areas for the introduction of additional structures in the metal foil are provided. These do not necessarily have to be dated primary and / or secondary shaping area spatially separated his. However, spatial separation is often an option.
- embossing stamp for the introduction of the Secondary structure and means for centering the metal foil are provided.
- the means for centering the metal foil ensure an exact Position the metal foil in the progressive die.
- Embossing stamps are advantageously in the upper part of the tool and Lower part of the tool provided.
- the embossing stamp in the Tool upper part is the secondary structure in the wave crests of the Primary structure introduced.
- the dies in the lower part of the tool serve to introduce the secondary structure into the troughs of the Primary structure.
- the waves of the secondary structure preferably a higher frequency and a lower amplitude than that Waves of the primary structure.
- the means for centering the Metal foil as spring-loaded clamping means in particular consisting of a spring-loaded guide plate with guide insert and a spring base, are formed, the surfaces of the guide insert and / or of the spring base at least partially like the primary structure of the Metal foil are molded.
- the special shape of the surfaces serves the metal foil provided with a primary structure in one to be able to hold the first work step by means of the spring-loaded clamping means.
- the primary shaping area at least one interacting with a sprung guide plate Stamp provided for the introduction of the primary structure into the metal foil is.
- the primary structure is not over the entire length of the Metal foil, but introduced in stages. It is necessary that Size of the stamp so that it is guaranteed that a The flow of foil material during forming is guaranteed because the otherwise very thin metal foil can tear.
- Another beneficial one The design provides that the lower stamps are rigid and the upper stamp can be moved, for example, via the toggle lever.
- the spring-loaded guide plate with guide insert therefore has a Dual function.
- the secondary molding area it serves as a part of the clamping means for centering the metal foil while it is in the primary Shaping area for shaping the metal foil is used and with a Stamp cooperates.
- the surface of the stamp and the of the sprung guide insert are designed so that the Primary structure of the metal foil in the form of a, preferably continuous, Wave results.
- the secondary structure is then in this primary wave, again in the form of a wave, in the secondary shaping area brought in.
- stamps in the feed direction of the metal foil spatially arranged one behind the other and one after the other, in particular against the direction of the metal foil, can be actuated. It points the surface of each stamp is a partial section of the Primary structure for insertion into the metal foil.
- every toggle lever mechanism consists of one Middle section exists, which with at least two toggle levers Stamp and over at least two other toggle levers with one Base plate is hinged, the middle part with the Toggle levers is arranged so that the stamp by a Sideways movement of the middle part is actuated. As a sideways movement the pivoting movement of the middle part is designated here.
- a toggle mechanism is a drive for converting a vertical movement the upper part of the tool or the lower part of the tool into one Sideways movement of the middle part of the toggle mechanism assigned.
- the order of the stamping operations of the individual stamps in the primary Timing the shaping area is advantageously provided for each drive one with the upper or lower tool part in Operationally connected standing, preferably spring-loaded, bolts is, the bolts of the individual drives are of different lengths exhibit. This is to ensure that the first secondary shaping area nearest stamp or the closest stamp group is activated and then the further stamps or stamp groups in Sequence to be operated against the feed direction of the metal foil.
- This object is achieved in that a metal foil in one Progressive tool in a machining process with a first and at least one second structure is provided, the secondary structure superimposed on the primary structure, and in which in all or selected transition areas between the first and at least second structure metal foil material is removed.
- This method according to the invention advantageously allows production extremely thin, structured metal strips in one machining step a single tool while maintaining the lowest Manufacturing tolerances.
- the method according to the invention is more economical than that described in the prior art, since it is on a Machine can be done with a tool because Progressive dies with a punching machining step, and Can reshape.
- the inventive method reduces the Formation of burrs on the work pieces so that a complete catalytically active surface deposited on the metal support can be.
- the work step of the invention Material removal also ensures that one is out of the material manufactured catalyst has a significantly longer service life in everyday use has the stresses within the Metal foil degraded, and notch effect at the transition areas between the first and second structure can be avoided.
- the method advantageously provides that work steps of the Processing process take place at different times or individual Working steps of the machining process are offset in time and space respectively.
- the time offset of the work steps enables one Refill of the material during the successive Forming processes so that micro cracks or structural breaks are avoided become.
- too a spatial variation of the work steps within the Progressive tool so that even particularly sensitive Metal foils can be processed with very good results.
- the progressive die is the primary and secondary Structure is preferably introduced as a wave structure in the metal foil the effective surface without corners that are disadvantageous for the galvanization and edges significantly enlarged. Corners and edges also lead to Formation of dead volumes, which is the conversion rate of the catalyst reduce and must therefore be avoided. Training the Structure as a wave structure also has the particular advantage that the effective surface, but not the flow resistance is enlarged beyond measure.
- the secondary structure in the crests and / or in the troughs of the primary structure is introduced and the waves of the secondary structure preferably a higher frequency and a lower amplitude than that Have waves of the first structure.
- foil material by punching out preferably in the form of an elongated hole, in the transition area between the first and second structure is removed.
- the punch is in the form of an elongated hole particularly advantageous and easy to implement, the invention comprises but also other shapes such as bone, circular or double-hole shape.
