Strip layout

• Strip development refers to the choice of operations to be performed in each of the stations in a progressive die. It is essential that the strip is properly developed since it will ultimately result in the best design of the die. Some of the principles that are to be followed are as follows:

• Always pierce the piloting holes in the first station, this helps in proper registering of the strip for the subsequent stations.

• . If numbers of punched holes are very close, distribute them in more than one station so that the die block remains strong. Similarly, holes nearer to the edge should be done in separate stations.

• . A complex contour be normally split into a combination of simple shapes and punched out a number of stations. This eliminates the expensive way of making a complex punch.

• Use ideal stations in the strip development stations refer to the stations in a progressive die where no piercing or blanking is done. Some of them are used for simple piloting.
