Substituição do sistema de acionamento hidráulico da mesa de uma retíficadora plana tangencial por um sistema eletromecânico

Abstract

Tangential flat grinding Sulmecânica brand, year 1968 of 800x200mm table, driven by a hydraulic unit. The machine in question worked with a hydraulic drive unit from the table, which moved its main pistons, longitudinal feed with a double piston rod, causing the movement of the table and advance the cross with a single piston intermittent or continuous advance. Replacement of Hydraulic Unit came because of an idea to generate the same moves from the use of an electromechanical drive system. The materials used for this adaptation were largely remnants of matter or parts of other machines, the machines were used for machining, lathe, milling machine, bench drill, hand drill, esmiriadeira, flat grinding machine, electric welding machine, files, taps etc. The entire set was designed in Auto Cad-2013 solid program, which allowed visualization of all the pieces, it was imported into Inventor 2011, which facilitated the design, simulation efforts on the parts, given the choice of materials. Another program was used 3D Studio Max, which simulated the movements, giving life to our work. The results were satisfactory, with the reduction of noise by up to 20% drop in the cost of maintaining and improving the performance of the machine, producing better finish on machined surfaces, positive improvement obtained by the reversal of the longitudinal table without impact, providing more accuracy.
