Steel work design and analysis of a 40-ton constant temperature hydraulic press

Abstract

This study presented the analyses of the design and construction of a motorized 40-ton constant temperature hydraulic press, for constant temperature compression purposes of fibre matrices. Standard design considerations and calculations were done to ensure the selection of effective and efficient components for the development of the machine. The construction of the machine involved standard manufacturing processes which involved marking out, cutting, drilling, machining and welding processes. The design was motorized for the purpose of increasing mechanical advantage as against hand-powered press. Design analyses were carried out to facilitate accurate dimensioning of the various parts of the hydraulic press. For adequate spring selection, the spring analysis of the system was also done. On testing of the finished device, no sign of leakages and system failure were observed. The effect of press time, temperature and pressure on the density of test samples, during a manufacturing process using the developed machine showed good working condition on both the compression and heating processes of the machine.

Numerical calculation of a 20MN heavy duty hydraulic press for analyzing the double frame pre-stressed steel wire winding

“…If we want to equivalently model the preload of the wire by equivalent temperature loading, we must know the equivalent temperature applied to the wire. The equation for the relationship between temperature and structural stress is known as (Okolie et al, 2020).…”

Análisis del diseño y construcción de una prensa manual para comprimir latas

“…El término proviene de la palabra catalana premsa y está relacionada con la aplicación de una fuerza. Existen diferentes tipos de prensas, según el propósito en cuestión [3]; teniendo en cuenta algunos ejemplos, la prensa hidráulica motorizada que fue diseñada y construida con la intención de aumentar la ventaja mecánica en comparación con la prensa manual tal como lo describe Okolie et all [4]. Otra variante, es la compactación con prensa de rodillos de rastrojo de maíz molido grueso y pastos perennes nativos para producir productos compactados para un transporte eficaz en camiones según Kaliyan et all [5].…”
