Precision guiding of sheet-metal mold (English)
Abstract [en]

The question for this work was: How to design and control the guidance of sheet metal molding tool in order to achieve precision over time.The work has been based on the method of product development where the product development is methodically done, individual opinions are eliminated to the greatest possible extent.Several different concepts have been developed, which have since been evaluated in a selection process that has been done by using elimination matrice and criterion weight matrice.A knee joint mechanism has emerged from this selection process. The main advantage of the knee joint mechanism is that it is least affected by the dynamic forces that excite in the molding tools. When the magnitude of the dynamic forces could not be determined, a mechanism emerged that largely eliminates this problem.

Abstract [sv]

Frågeställning för detta arbete var: Hur skall en styrning av ett formverktyg för tunnplåt utformas för att kunna uppnå precision över tid.Arbetet har utgått från metoden om produktframtagning där produktutvecklingen sker metodiskt och individuella åsikter elimineras till största möjliga utsträckning.Flera olika koncept har tagits fram, dessa har sedan har sedan utvärderats i en urvalsprocess som har använts sig av elimineringsmatris samt kriterieviktsmatris. Ur denna urvalsprocess har en knäledsmekanism framkommit. Knäledsmekanismens främsta fördel är att den är minst påverkad av de dynamiska krafterna som exciterar i formverktygen. Då storleken på de dynamiska krafterna inte har kunnat fastställas framkom en mekanism som till stor del eliminerar detta problem.
