Diseño y construcción de una prensa hidráulica para corrección de bordes de láminas metálicas

Abstract

The present work aims to design and build a hydraulic press for edge correction of metal sheets for “Dicomsa Construcciones”. The main use of the machine is to generate cuts and punching of complex geometries to avoid the use of conventional tools such as grinders. The design was developed through the use of concurrent engineering and technical specifications were established based on the needs of the customer. The prototype modules were determined that generated an optimal result for the construction of the press. The cutting force of the press was determined according to the most demanding cutting geometry in Dicomsa. In order to corroborate the calculation, design and construction of the machine, sealing, die-cutting and bending tests of ASTM A36 steel sheets and 430-304 stainless steel were performed. In all tests, it was verified that the cylinder did not exceed the 3000 psi of pressure for which it was designed. There were no leaks and the oil temperature did not increase during the test time. The analysis of the costs indicated that the design and construction of the press amounts to a total of 6 204,14 (USD).
