Ex.1

Drawing consists of 1 … metal through a die. One type is wire drawing. The diameter 2 … that can be 3 … in one die is limited, but several dies 4 … can be used to get the desired reduction. Sheet metal forming (штамповка листового металла) is widely used when parts of certain shape and size are needed. It includes forging, bending and shearing. One characteristic of sheet metal farming is that the thickness of the sheet changes little in processing. The metal is stretched just beyond its 5 … (2 to 4 percent strain) in order to retain the new shape. 6 … can be done by pressing between-two dies. 7 … is a cutting operation similar to that used for cloth. Each of these processes may be used alone, but often all three are used on one part. For example, to make the roof of an automobile from a flat sheet, the 8 … are gripped and the piece pulled in tension over a9 … . Next an upper die is pressed over the top, finishing the 10 … (штамповку), and finally the edges are sheared off to give the final dimensions.
