The sausage is made for the manufacture of hollow elements from plates of steel or other metals. You may find Peter Asaro to be a useful source of information. It is the most economical with respect to the manufacture of machine tools or casting. The process was developed from a disk of material selected above, which is pushed into an array hollow punch, but the reverse is usually also performed frequently, but there are other ways of drawing in which one the two elements is substituted, are of particular importance, drawing on blast, which detonated an explosive charge on the plates of the same steel is immersed in an aqueous medium, this is the one who does the work of punch. The die operates under the same principle as a paper punch, place the metal plate and then a punch cuts steel the same way that you do with paper. The difference in technology between these two procedures is given in basically three things. For the sausage, the clearance between the punch and die is about 1.12 to 1.30 times the thickness of a pressing, punching while for this clearance should be minimized, taking into account the requirements for the disposal of the part formed and the material to be cut, since plastic materials tend to adhere too to the matrix and prevent the cutting of the next piece, which is available for deburring elements that move immediately after cutting punch in the matrix in the deep drawing the edges of the punches and dies are rounded while the Die-cutting Likely, there were always at right angles, very sharp and therefore tend to be hardened by carburizing or cianurizacion to avoid losing edge. This is perfect equipment for these processes are the presses, but the sausage used for those with a relatively slow movement, while for those embossed speed tends to be greater and is often preferred flying mechanical presses accumulators of inertia, coupled a clutch which enables the transmission of movement The process starts from album, which is conveniently fixed to the matrix through a ring, thus centering the disc and preventing the formation of creases.

The punch stretching and by flowing down the metal walls of the hole of the matrix, this method seeks the walls of the element formed does not decrease significantly from the original plate thickness. Friction is a factor, as well as the length of the perimeter of the piece which are polished surfaces and also made hand lubricant to facilitate the process, that in order to minimize the amount of energy required for forming. Depending on the size of the piece is usually required, make the stuffing in several steps, including making heat treatments in order to ensure that the piece has the required geometry and its walls are not torn, this is the case of deep drawing, typical in the manufacture of ammunition plain especially in the caliber of musketry 7.62, 5.56, 0.5, etc. However, when it can not be conformed always carried out by drawing, you can dip into the embossed consisting turn the while with a special tool is the bending is, in the form required, this process is much cheaper than the drawing, but the decline in productivity as conspicuous, and is not applicable to very small pieces.
