Metal deep draw stamping oil pan

An oil sump stretch forming process, the use of material damping composite steel plate as the oil pan, described damping composite steel plate as the three layers composite structure, in the three layers composite structure, on both sides of the surface of deep drawing steel sheet, middle of thermosetting resin binder, after preliminary forming in the oil sump oil pan pressure increase within the mold, through to the oil sump exert high pressure fluid, Get the desired oil pan shape; Described within the oil sump up pressure mold including upper die and lower die, and described the module has placed after the preliminary forming oil sump oil sump cavity, the upper die and lower die clamping, upper die cavity closed oil pan, described between upper die and lower die is formed with the mouth cavity connected oil, oil pan oil mouth and described the oil outlet oil pump connected, The lower die comprises a lower die seat, the lower die fixing plate, the lower die bottom plate, the lower die seat is used for supporting the lower die fixing plate and the lower die bottom plate, the lower die bottom plate is provided with the main part of the oil pan cavity, the lower die fixing plate is used for positioning the oil pan on the die.

Different materials have different tensile properties.

1) The limit of elongation, that is, the proportion of blank diameter to stamping diameter. Stainless steel materials are controlled from 2.1 to 2.2 and carbon steel is controlled from 2.15 to 2.5.

2)Stainless steel can be drawn a second time after deep drawing, but unlike carbon steel, stainless steel cannot normally be drawn to the same degree as the first, unless heat treated. Stainless steel equipment requires one to two times the strength of carbon steel equipment.
