“…Blows with small load and large billet deformation are qualified as soft blows and the associated efficiency is high, between 80 and 90%. For hard blows, high load and small billet deformations are noticed and efficiency is low, between 50 and 20% [38]. In our case, blows 1, 2, 3 and 4 can be considered as soft blows, whereas blows 5 and 6 are intermediary blows, between soft and hard blows.…”

Energy saving has become a real issue in process management and has led to the analysis of the energy consumption of forging machines, for the purpose of optimization. This study focuses on the amount of energy lost due to machine behaviour during the forming process. A spring-mass-damping model of the machine and tools system is associated with a billet model to describe hammer-forming operations only during the forging phase. The model parameters are identified with experimental measurements of process variables during a stroke, providing parameters specifically adapted to the machine-tools system. Then, model predictions are validated by the experimental upsetting of steel and aluminium billets. The model accurately predicts forging process variables for consecutive blows with different materials. The decrease in process efficiency and the evolution from inelastic to elastic blows after several strokes on the same billet are also predicted by the model. This methodology provides a new, tailored solution that enables forging manufacturers to predict the forging energy consumption of their own machines. The approach developed in this work concerns gravity drop hammers but is also transferable to other energy-driven machines.Jean-François Mulljeanfrancois.mull@ens am.eu

In this paper, a novel type of low frequency vibration plastic forming equipment is proposed, in which the slotted tubular permanent magnet synchronous liner motor (slotted – TPMLM) is the core component and plays the roles of power source and vibration source. So, this paper focuses on the research about the design of the slotted - TPMLM. The suppression and optimization of motor thrust fluctuation has always been a hot research issue. But that is not the purpose of this article. Here, the effect of the length of stator core on end force and the influence of the number of poles and slots on the cogging force are discussed in detail. The purpose is to design the thrust fluctuation of slotted – TPMLM reasonably so that the thrust fluctuation can be used in the low frequency plastic forming. The slotted – TPMLM is designed, manufactured, and tested. The experimental results show that the motor can output thrust with periodic fluctuation (low frequency, about 4.8 Hz), and the thrust fluctuation accounts for about 16.5% of the average thrust, which meets the metal low frequency vibration plastic forming requirements. Consequently, the low frequency vibration plastic forming equipment can be realized, which contributes to the field of the plastic forming.

Compared with the conventional servo press, the direct drive press even has no transmission mechanism, so it has advantages in controllability, precision and energy management. But, the forging capacity of the direct drive press is limited by the power of the linear motor. In this paper, a novel press driven by a tubular permanent magnet linear motor (TPMLM) is presented, and a symmetrical toggle booster mechanism is specially proposed to enhance the forging capacity. The mathematical model of the toggle booster mechanism is established, The TPMLM is designed, and the experimental prototype of the novel press is manufactured. The forging capacity and dynamic characteristics of the press are studied theoretically and experimentally. The results show that the introduction of the symmetrical toggle booster mechanism enriches the dynamic characteristic curve of the press and enhances the forging capacity. Therefore, the structural parameters of the toggle mechanism and the working position of the slider can be adjusted to meet different technological requirements. In addition, based on the research work, three directions are proposed to improve the forging capacity of the novel press. The research contributes to the performance optimization and development of direct drive press.
