“…A three-degreeof-freedom mathematical vibration model of a high-speed punching press was established in order to predict the motion state under different working conditions, as well as the influence of load fluctuation on motor speed [14]. These two methods can effectively solve the flutter generated in the press work.…”

Inertia force is an important factor for operation stability and stamping precision of high-speed punch; adjusting drive torque of high-speed punch can realize effective control of inertia force. In this paper, a kind of 600 KN multilink high-speed punch inertia force balancing mechanism was designed. The calculation model of ideal inertia force was proposed based on conservation of energy and numerical analysis method. In addition, the calculation model of ideal driving torque were analyzed, simplified, and corrected by using numerical calculation and simulation methods, which solved the problem of controlling inertia force from the perspective of driving torque and realized the stability strategy planning of high-speed multilink punch press. Finally, the proposed ideal driving torque calculation model was simulated and verified by ADAMAS and bottom-dead-point accuracy test was carried out.

“…The heat transfer fin part (as shown in Figure 2) is manufactured with a 13-position progressive stamping die (as shown in Figure 3) installed on a certain high-speed punching press. 16 The material of the heat transfer fin is aluminium foil with a thickness of 0.115 mm. The stamping process of the fin part consists of multi-stage drawing, elliptical-hole punching, flanging, louver punching, trimming-striping cutting-off and so on.…”

The multi-domain modeling and simulation of the precision high-speed punching press was carried out using the software SimulationX in this article. The key technical problems of the multi-domain modeling, such as the establishment of the subsystems of mechanics with accurate structures and dimensions, improvement of modeling accuracy and simulation efficiency by dividing and dealing with components in group and import of the displacement-depended stamping forces on the stamping dies, have been resolved to establish the integral multi-domain model, which contains subsystems of mechanics, hydraulic and servo driven of the complete punching press. Vibration quantity of the punching press was predicted through simulation, and validity of the multi-domain model was confirmed by experimental measurement. The vibration reduction in the punching press based on the topology optimization of the slider and design of rotational speed variation curve of the servo motor were investigated. The results show that through topology optimization, the mass of the slider could be decreased under the premise of guaranteeing the structural strength, by which the vibration quantity of the punching press can be decreased; rotational speed of the servo motor could be decreased during the stamping period by designing the rotational speed variation curve, which leads to a decrease in acceleration and vibration of the slider during that period, with which the forming precision can be guaranteed.
