Abstract

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines Formbauteils ungleichmäßiger Dicke (7).The invention relates to a method for manufacturing a molded component of uneven thickness (7).

Um eine kostengünstige Herstellung eines Formbauteils mit einer gewünschten Variation seiner Dicke zu ermöglichen, wird vorgeschlagen, dass mindestens zwei Bleche (3,4) sich zumindest teilweise überlappend zwischen mindestens eine rotierende erste Rolle (1) und mindestens eine entgegengesetzt zur ersten Rollen rotierende zweite Rolle (2) geführt werden, die Bleche (3,4) gemeinsam zwischen den Rollen (1, 2) durch Rollprofilierung verformt werden, und die Bleche (3,4) miteinander verbunden werden.

Figure 00000001
In order to enable inexpensive production of a molded component with a desired variation in its thickness, it is proposed that at least two sheets (3, 4) overlap at least partially between at least one rotating first roller (1) and at least one second roller rotating counter to the first roller (2) are guided, the sheets (3, 4) are deformed together between the rollers (1, 2) by roll profiling, and the sheets (3, 4) are connected to one another.
