Adaptive system for automatic control of the fine drawing process

The paper considers the technological process of deep drawing, taking into account high degree deformation metal and small thickness (0.5 mm) workpiece. Given complexity impossibility its representation in an analytical form, uses form a phase portrait plane drawing force movement hydraulic press punch. Phase trajectories mentioned determine geometric dimensions product, characterize stresses deformations during determines structure control algorithm. digital positional tracking system considered work includes electromechanical, hydraulic, pneumoelectric electronic links. provides precision positioning punch with speed. ideal mathematical model extraction process. As result comparing real process, possible difference is revealed due to interference resulting makes it additional effect on speed circuit order compensate for misalignment. Thus, stabilization function realized. descriptions all parts system, dynamic characteristics disturbing effects following are considered: hardening, unstable friction that occurs when workpiece pressed, change drawn matrix, corrugation, thinning transition bottom part side wall product. disturbances without question did not fully ensure quality products. marriage, significant production costs took place. materials numerical data links were obtained by example manufacturing cylinder OP-2(3)-ABCE powder fire extinguisher produced at ZPO plant Itself (fire fighting equipment plant).
