Modern steel metallurgy industry one starting point that develop in to processing speeds. Disc shears is an important equipment among them.Disc shear machine set up in finishing production line. It usually uses to cutting neat the movement steel plate longitudinal edge and cut the strip into narrow one. It can be divided into two kinds according to its use: disc shears of cut stencil plate’s side and disc shears of cut strip.The disc shears design calculation is taken in makes the massive investigation to the ANSHAN steel group Cold-rolling mill 1700 transverse cutting aircrew as the background. We have thorough understanding to the disc shears and the correlation equipment. We had very designed to the main transmission system, depress the system and gap adjustment organization, we are carry on these designs from the materials mechanics angle, dynamics and economic. The main content including electrical machinery selection, Axis and gear design, Implementing agency design and so on, and the same time, we make the optimized improvement and the intensity examination to the major parts. This design improvement spot: First, in radial clearance adjusting mechanism link motion gear, second, backlash adjustment increase self-locking installment. Third, the width control uses the planet gear speed reducer. Finally increased has measured the fast organization. This disc shears may use in the transverse cutting unit, the acid pickling unit generally and so on.Key words: Disc shear, strip, depress the system, the intensity
