“…According to Thomas et al [1], a hydraulic press is a machine press which uses hydraulic cylinder to generate a compressive force to perform various pressing operations such as metal forging, punching, stamping, etc. The press provides an efficient means of pushing and pulling, rotating, thrusting and controlling load [2,3].…”

In this study, a reconfigurable hydraulic press brake was designed using Solidworks and simulated on a hydraulic Automation Studio Fluidsim. The designed press brake comprises of the frame balance, conveyor rollers and support, belt, chuck, six hydraulic cylinders assembled with bolts and nuts. The buckling force was determined analytically and compared with the Finite Element Analysis (FEA) simulation to prevent distortion of length and section. The Von mises stress theory was used to determine the stress, resultant load and displacement. The results obtained from the FEA simulation were compared with the mechanical properties of the hydraulic press brake. The maximum stress induced is significantly lower than the tensile strength of the hydraulic press brake. Hence, the stress induced due to bending cannot cause the cast alloy to yield. Also, the buckling force significantly exceeds the resultant force giving no chances for buckling. The designed hydraulic press brake is flexible enough to control using hydraulic cylinders and enhances sufficient strength and rigidity during clamping and loading conditions.

“…The traditional press machine cannot meet the strict requirements on the deep drawing of thin sheets. There is a high market demand for press machines supporting userdefined kinematic indices like stroke and speed [17][18][19][20][21]. Huang et al [22] provided an overall design plan for the hydraulic control system of computer numerically controlled (CNC) servo press machine, checked the pressure and heat losses of the system after determining the components and parts, and constructed an Adams simulation model on the stability, observability, and controllability of the system.…”

The stability and reliability of hydraulic control system have a direct bearing on the overall dynamic performance of the press machine. Hydromechanical analysis on the hydraulic control system is of theoretical and practical significance to improving the transmission performance and structural design of the entire press machine. From a quantitative perspective, this paper firstly analyzes the fluid transmission features of the hydraulic control system for the press machine, and presents the fluid transmission route and design drawings of the hydraulic control system. The next step is the design of the hydraulic control system. The authors specified the steps of design and calculation for the hydraulic control cylinder, and the principles for determining the power of the diesel engine. After that, experiments were carried out to verify the dynamic and static features of the designed system, and prove that our system is scientific and rational.
