Metal Stamping Process Using A Wire Preform For Stamping Parts Assy



The process can significantly reduce the amount of scrap material and thereby reduce manufacturing costs. Stamping Parts Assy are fabricated by a variety processes such as casting, die casting, and forging. One of the more common processes used for manufacturing metal parts is called metal stamping, which has been in use for over 150 years. Metal stamping, which in general involves taking a flat metal sheet and converting into a shaped article using a die and press, is a cost-effective process because it permits metal parts to be manufactured at high production rates. The stamping press has a die means and a punch means which together are used to form blanks from the initial sheet of stock material.
These blanks are then subjected to further stamping procedures to form metal parts. After the preforming stage, the shaped wire or preform is then subjected to a flattening process to achieve a "blank" from which the desired product work piece will be obtained via a stamping process. Wires of other cross sections such as square, rectangular, can also be used. For example, a shaped section of wire having an effective or nominal diameter of, for example, 3 to 50 mm, preferably5 to 20 mm, can be flattened to a preformed piece of metal having a thickness of, for example, 1 to 30 mm, such as 1 to 25 mm or 8 to 30 mm, preferably 2 to 8 mm, by passage through a mechanical or hydraulic press that applies a pressure of, for example,60 to 1000 tons, preferably 100 to 600 tons.
The wire can be flattened by any typical process suitable for applying the requisite pressure to a piece of metal. The dimensions and tonnage listed above are merely provided as examples and are not intended to limit the invention. Thus, the width and thickness of the blank are determined by the selection of the nominal diameter of the wire and the amount of pressure imposed during the flattening process. In other words, in a conventional procedure blanks are cut and formed from a sheet of flat rolled metal. This procedure inherently imposes material costs due to the resultant scrap material.
