Increasing the drawing height of conical square cups using anti-lock braking system (ABS)

Abstract

This paper deals with increasing the drawing height of metal conical square cups with anti-lock braking system (ABS). A novel technique enabling higher drawing height than that achieved in the conventional deep drawing process is introduced, and the principle of the process is explained in this paper. Results of experiments conducted using aluminum alloyed Al-1050 blanks of thickness of 1 mm to draw conical square cups are reported here. Measured drawing load, drawing height and thickness distributions were compared with those obtained from the conventional method. The experimental results showed that higher drawing height of the cup can be achieved by the use of ABS.

Research on Kinetic Energy Recovery of Energy Vehicle ABS Solenoid Valve Based on the ELM Deep Learning Model

“…The main reason is that it is difficult to break through core technologies, such as solving energy problems. Energy source limitations increase the service life of the energy source and reduce the manufacturing cost of electric vehicles [ 1 ]. Under the current technical conditions, only the method of braking energy recovery can be used to increase the mileage of electric vehicles [ 2 ].…”

“…How to distribute the relationship between friction braking and regenerative braking has become a key issue for regenerative braking systems [ 5 ]. If the braking energy regeneration system and the ABS system are reasonably coordinated and controlled, the economy of the vehicle can be improved, and driving safety can be enhanced [ 6 ]. Therefore, it is extremely necessary to study the kinetic energy recovery of ABS for electric new energy vehicles.…”

Experimental investigation of the effect of specially manufactured blank (SMB) materials on deep drawing

“…The slight decrease in the maximum load in these cups was due to the effect of the decrease in the deformation resistance of the flange part of the material. 22 In addition, a decrease in punch load was observed in the SMB with 3°and 4°due to a decrease in material volume. This situation also affected the wall thickness of the deep drawn cups.…”

“…This situation can be explained due to the increase in the tensile force and the concentration of stress that occurred at the punch arc point. 22 After 10th point, the thickness of the cups increased. The cup obtained by deep-drawing of unmachined blank with uniform thickness (2 mm) in neck giving zone (between 14th and 17th points) of thickness of the cup reduced, then the wall thickness continuously increased to the upper part of the cup.…”

“…Similar situations are found in the literature. 3,[22][23][24] Towards the end of drawing process, the materials that had earing, deformation hardening, thickening as a consequence of thinning-drawing process (ironing) punch force made peak rising again. Later, in earing area due to the amount of material decreasing rapidly, punch load also falls abruptly.…”
