LIMIT THE POSSIBILITY OF FORMING AT CRIMP TUBE STOCK MATRIX THE CONICAL SHAPE
In the method of the base, which is based on a joint decision of approximate differen- tial equations of equilibrium and yield conditions, taking into account interfaces on the bor- ders of plots mathematical model was developed crimp tube Zago-reparation in the conical- shaped matrix that allows to determine the stress-strain state of the blank and power parame- ters of the process and takes into account mechanical properties of the material.
