Hydroforming Of Sheet Metal Pairs

In order to improve.

Hydroforming of sheet metal pairs.

Especially the oil pan is a difficult part to manufacture without defects by the conventional forming process. Procedure and device for manufacturing printed parts with very smooth cutting surface and increased functional surface. 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. Hydroforming of sheet metal pairs is a new field of investigation for manufacturing engineering.

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 metals has four major types as shin et al. While metal stamping has been the conventional method of choice for metal forming there is little doubt today that hydroforming is the definitive future of metal forming. We provide hydroforming solutions that quite literally stamp out all the drawbacks associated with the metal stamping process.

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. 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. Manufacturing method of sheet metal product with spaced projections es2341579t3 en 2010 06 22. In conventional sheet hydroforming process the channel s feature sizes e g the channel width fillet radius etc are much greater than the sheet s thickness so that the.

These two parts are known to have geometrical constraint in each corner. An oil pan shape and a rectangular cup. 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.

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. Hydroforming is commonly used within the automotive and aerospace industry where complex shapes by hydroforming can be produced stronger lighter and more solid. 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.
