“…In consideration of these defects, an improved energy matching method for two combined hydraulic presses was proposed to utilize the potential energy. The drive system is shared by the two presses in different times to reduce the energy loss caused by the slide return operations, so that the energy efficiency of the drive system is improved [63,72]. Furthermore, this method derived a more energy-efficient system with a double-actuator in a hydraulic press to reduce the potential energy as shown in Figure 9.…”

Energy efficiency improvement and environmental impact reduction are emerging issues in the manufacturing industry. Aside from cutting, metal forming is also an important process in manufacturing. Metal forming is energy intensive because of the low energy efficiency of the used metal forming press. Although many literature reviews focused on the energy reduction and energy efficiency of machine tools, a comprehensive literature review of metal forming processes remains lacking because of the great difference between cutting machines and forming equipment. In addition, methods for energy efficiency and energy-saving still need to be promoted in metal forming. In this review, a novel hierarchy of the metal forming system was presented to describe the relationship among the equipment, process, and manufacturing system, providing a guideline of methods for energy efficiency and saving in metal forming. Then, existing energy consumption modeling and estimation theories and methods were discussed from two aspects. One is energy monitoring and modeling of metal forming equipment, and the other is process energy analysis of metal forming based on different parameters. On the basis of the hierarchy of the metal forming system, the present methods and technologies aiming to promote energy efficiency and energy saving effects were discussed from the aspects of equipment design and control, process optimization, and scheduling management and use. Thus, this review may serve as a reference for the decision-making of producers and managers to realize energy efficiency and energy saving at the system level. In addition, the major points that need attention are accurate energy models and control of forming equipment as well as the integrated optimization of equipment, process, and scheduling.

“…On the other hand, on the premise of satisfying forming quality, reducing process energy consumption as much as possible to achieve the minimum final energy demand . The hydraulic fine blanking machine has many advantages, such as a high power to mass ratio, high stiffness, and a strong load capacity, but only about 7% of the input electric energy can be converted into forming energy [8]. The research on improving the energy efficiency of hydraulic equipment has attracted wide attention and obtained remarkable achievements [9][10][11].…”

As an advanced sheet metal processing technology, fine blanking is usually used to produce precision parts for automobiles, aerospace, and other industries, but the forming process consumes huge energy. The previous research on fine blanking has mainly focused on improving the forming quality, but the analysis of process energy consumption is rare. Firstly, the energy consumption of the fine blanking process was analyzed theoretically, and a theoretical model was established. Then, the Ludwik hardening model and Oyane fracture criterion for 16MnCr5 were constructed. Next, the orthogonal experiment was designed to analyze the influence and degree of the main process parameters on surface quality and process energy consumption. Among them, blanking clearance, blank holder type, and blank holder force have the greatest influence on the size of the shear zone, energy consumption of deformation, and total process energy consumption, respectively. Furthermore, the influence mechanism of key process parameters on process energy consumption was deeply revealed from the perspective of deformation area, hydrostatic stress change, and material flow velocity, which provided a theoretical basis for green fine blanking. Finally, the fine blanking experiment was carried out to verify the great difference in surface quality and energy consumption under different process parameter combinations. This paper provides a theoretical direction for the fine blanking process, which can not only get high surface quality but also save energy consumption.
