Hydraulic fineblanking press is a kind of high-end hydraulic metal forming devices and widely applied in automotive and appliance industry. However, it suffers from the defeat of high energy consumption low energy efficiency. To solve the problem, this study proposed a power-matching strategy by using a novel controllable accumulator which can control the precharge pressure, output flow with high precision. Firstly, the energy characteristics and working performance requirements of the large-sized fineblanking press in a working cycle were investigated. Then, the energy consumption mathematic model coupling with the controllable accumulator was built for designing the key parameters of the accumulators. Based on the load characteristic and the energy model, a controlling strategy of the controllable accumulator was proposed to reduce the imbalance degree of the supplied and demanded power and improve working performance by designing working route of the controllable accumulator. Finally, a detailed hydraulic schematic was designed and applied on the 1000 ton hydraulic fineblanking press, which was validated with simulation model. The results show that compared to the traditional system, the energy efficiency of the novel system is improved by 20.35% with lowering the input energy by 169.4 kJ. Besides, the vibration magnitude of the slide block is decreased a lot and the working production efficiency is improved by 10% compared to the traditional system.

“…Hydraulic presses are frequently used in a variety of forming operations in industrial applications because of their advantages of having a high power-to-mass ratio, high rigidity, and high load capability [1]. Although hydraulic systems are frequently utilized in engineering machinery, their high energy consumption and low energy efficiency restrict their growth and utilization [3]. The low energy efficiency of the motor and the high energy consumption brought on by the pump unloading are significant issues for hydraulic presses [1].…”

“…More than 57.1 billion kWh would be saved annually if 20% of energy usage were cut, which could reduce carbon emissions by 47.62 million tons [10], or the amount of CO 2 absorbed annually by 5.83 million hectares of the forest [10]. Energy efficiency promotion and energy savings for manufacturing systems and equipment are currently receiving more attention [3]. Given the loss of resources and energy, climate change and carbon emissions are currently major problems [11].…”

With the growing cost of electrical energy, the necessity of energy-saving implementation in industries based on energy audits has become a major focus area. Energy audit results indicate energy-saving potential in an application and require the physical presence of the auditor’s team for monitoring and analyzing the energy consumption data. The use of Industrial Internet of Things (IIoT) for remote data monitoring and analysis is growing and new industrial applications based on IIoT are being developed and used by various industrial sectors. Possibilities of a mixed method of physical and remote energy audit using IIoT in industrial applications and its advantages as proposed in this research work needs to be explored. Existing hydraulic press machines running with direct online starter (DOL) can be run with variable speed drive (VSD) for energy saving but this requires an extensive energy audit. Key electrical and operational parameters of the hydraulic pump motor were monitored and analyzed remotely using IIoT in this research work by operating the hydraulic press with DOL and VSD motor control methods one by one. The input power factor of the hydraulic pump motor showed an improvement from 0.79 in DOL control to 0.9 in VSD control at different motor loads. The hydraulic pump motor starting current showed a reduction of 84% with VSD control. The hydraulic pump motor’s continuous current was reduced by 40% and 65% during the loading and unloading cycle, respectively, with VSD control. Electrical consumption was reduced by 24% as a result of operating the hydraulic pump motor at 35 Hz with VSD control without impacting the performance of the hydraulic press. These results indicated more efficient control by changing to VSD control in comparison with DOL control. A combination of physical and remote energy audits as performed in this research work using the proposed IIoT framework can be utilized for implementing energy saving in hydraulic presses thus motivating industries to adopt available more energy-efficient technologies at a faster pace.

“…Machinery manufacturing is one of the pillars of human wealth creation. However, its manufacturing process consumes a large amount of resources and generates a lot of waste, which is one of the main causes of the current global serious environmental problems [1]. The machining system is a volumetric manufacturing system, and globally the energy consumed by machine tools in machining accounts for up to 75% of the energy consumption of the manufacturing industry [2], but the energy efficiency of the machining process is low, with an average energy efficiency of less than 30% [3].…”

Improving resource efficiency and reducing waste discharge are the inevitable trend of the development of sustainable machining system. Therefore, a data-driven sustainability evaluation method of machining system is proposed. The input (energy, materials, equipment, R&D and services), and output (wastes and products) data of machining system are collected. These dimensional data are processed by emergy. The emergy flow calculation model of the machining process is established for data modeling, and the sustainability evaluation index of machining system is constructed for data analysis. Finally, an engine base machining process is taken as case study for innovative practice; and the targeted process optimization is adopted based on its sustainability evaluation for innovative practice. The feasibility and effectiveness of the method are verified. This study provides theoretical and methodological support for promoting the sustainability of the manufacturing industry.
