Delay_System

22 QUESTIONNAIRE Preliminary information required for carrying out a first dimensioning of the hydraulic control system. The more precise the infor- mation, the easier it will be for us to determine the best suitable system. 1) No. of cylinders with controlled return and maximum contrasting force for each cylinder No. ____ cylinders with a force of _______ kgf each No. ____ cylinders with a force of _______ kgf each No. ____ cylinders with a force of _______ kgf each 2) Total force required during cylinder return phase F tot. return ______ kgf (must take account of the weights to be lifted and of the estimated friction) 3) Effective cylinder stroke CL = ______ mm Please specify whether: minimum extra-stroke margin is _______mm 4) Guide of the mobile unit of the blankholder (or die) activated by the hydraulic cylinders in the return phase is: Well guided Not much guided Not guided Options b) and c) preclude the possibility to make the hydraulic cushion with Special Springs’ delay system for the hypothetical lack of parallelism of the mobile unit in the return phase 5) Cylinder layout. Please illustrate the cylinder layout and indicate the axis: 6) Accessibility of cylinders for air bleeding operations during start-up (installation) accessible A accessible B accessible A and B non-accessible A and B
