Description

Bei der · üblichen Herstellung der Blechradiatoren werden die Gliederhälften aus einem Stück gepreßt, für jedes Modell ist eine besondere Preßform und für die großen Modelle sind Preßwerkzeuge von unwirtschaftlichem Ausmaß erforderlich, z. B. für die Herstellung von Modellen von vier verschiedenen Breiten und sechs verschiedenen Höhen sind 24 verschiedene Preßformen erforderlich. Die Herstellung einer 25 cm breiten und 100 cm hohen Gliederhälfte erfordert, einen Druck um 2500 qcm Fläche zu pressen.In the usual manufacture of sheet metal radiators, the link halves are made from pressed in one piece, for each model there is a special mold and for the larger ones Models, pressing tools of uneconomical dimensions are required, e.g. B. for the production of models of four different widths and six different Heights 24 different molds are required. The production of a 25 cm wide and 100 cm high link half requires to squeeze a pressure around an area of 2500 square centimeters.

Nach der Erfindung werden die Gliedlängen / aus dem glatten Blech g aus möglichst endlosem Band mit geringem Kraftaufwand in verschiedenen Breiten auf einem Werkzeug ze/ in Säulenform s gewalzt oder gezogen, wobei eine Säule eine Einheitsform s darstellt. Gepreßt werden lediglich die Gliederköpfe k, und zwar in beliebig einstellbaren Nabenabständen α aus dem zu Gliedlängen geformten Band'6 heraus, so daß nur für die verschiedenen Summen der Einheitsbreiten j — praktisch kommen zwei-, drei-, vier- und fünf säulige Fabrikationsformen in Betracht — verschiedene Preßformen erforderlich sind. Mit vier Preßformen lassen sich alle praktisch erforderliehen Fabrikationsformen herstellen. Zur Herstellung einer etwa 25 cm breiten Gliederhälfte von beliebig großer Höhe ist pro Doppelkopf lediglich eine Fläche von 25 X20 cm = qcm also nur der fünfte Teil der alten Herstellungsform zu pressen. Die Nabenabstände α der Glieder sind in weiten Grenzen beliebig verstellbar.According to the invention, the link lengths / are rolled or drawn from the smooth sheet metal g of as endless a band as possible with little effort in different widths on a tool ze / in a column shape s , a column representing a unit shape s . The members heads are pressed only k, in any adjustable hub intervals α out of the molded to link lengths Band'6 so that j for the various sums of the unit width - practically four- and five columnar fabrication forms are di-, tri-, in Consideration - different dies are required. With four molds all practically required manufacturing molds can be produced. To produce an approximately 25 cm wide link half of any height, only an area of 25 x 20 cm = qcm per double head, i.e. only the fifth part of the old production form, needs to be pressed. The hub spacings α of the links can be adjusted as required within wide limits.

Im Gegensatz zum Auspressen der Naben aus dem glatten Blech ist nach der Erfindung das für die Nabenform erforderliche Material in dem geformten Band vorhanden, ohne daß eine besondere Materialanreicherung nötig ist.In contrast to the pressing out of the hubs from the smooth sheet metal is according to the invention the material required for the hub shape is present in the molded band without a special material enrichment is necessary.

Fig. ι und 2 stellen schematiseh den Vorgang des Verfahrens dar. In Fig. 2 ist eine fünfsäulige und in Fig. 3 eine dreisäulige Fabrikationsform dargestellt.Fig. 1 and 2 show the process schematically of the method. In Fig. 2 is a five-column and in Fig. 3 is a three-column Manufacturing form shown.
