Hydroforming Of Sheet Metal Pairs

Procedure and device for manufacturing printed parts with very smooth cutting surface and increased functional surface.

Hydroforming of sheet metal pairs.

We provide hydroforming solutions that quite literally stamp out all the drawbacks associated with the metal stamping process. These two parts are known to have geometrical constraint in each corner. In order to improve. Hydroforming of sheet metal pairs.

Hydroforming of sheet metals has four major types as shin et al. They are characterised by the use of sheet metal pairs thus allowing an extended variety of shapes but they require special sealing and docking devices. An oil pan shape and a rectangular cup. 2002 and also thiruvarudchelvan and lewis 1999 noted in their work for types of sheet metal hydroforming process including hydrostatic deep drawing hydrodynamic deep drawing single sheet forming at high internal pressure single sheet hydroforming and forming a pair of.

Hydroforming is a way of shaping metals such as aluminium low alloy steel brass and stainless steel into structurally solid and strong light weighted pieces. Especially the oil pan is a difficult part to manufacture without defects by the conventional forming process. At the chair of manufacturing technology research on the hydroforming of sheet metal pairs was done in the last years using the deep drawing steel sheet dc04 with a material thickness of 1 5 mm. Manufacturing method of sheet metal product with spaced projections es2341579t3 en 2010 06 22.

Models simulations and experiments have concentrated on the feasibility of one particular process the hydroforming of unwelded sheet metal pairs and on the influence of the various. Testing of aluminium sheet material was done using aa 6016 alloy sheet of the same thickness and the results were compared to those of dc04. Micro mesoscale metal sheet hydroforming shf process is an efficient approach suitable for mass production to fabricate metal parts with micro mesochannel features. Hydroforming of sheet metal pairs is a new field of investigation for manufacturing engineering.

Hydroforming is commonly used within the automotive and aerospace industry where complex shapes by hydroforming can be produced stronger lighter and more solid. 26 and industrial examples of hydroformed metal pairs b 3132 a special case of sheet hydroforming is the hydroforming of welded closing sheet metal pairs figure 9a shows the scheme of the. Numerical simulations as well as analytical models have illustrated the need for proper load path control and for defined friction conditions in order to achieve optimal mechanical properties and geometric accuracy.
