Problems solved by technology

The two important processing parameters in the plastic forming process are forming pressure and forming displacement. The control of these two parameters is of great significance to the experimental research. The previous equipment did not take the two factors of pressure control and displacement control into consideration.

Abstract

The invention belongs to the technical field of plastic forming, and particularly relates to a supersonic vibrating auxiliary plastic forming device. The supersonic vibrating auxiliary plastic forming device is characterized in that a servomotor is arranged in the middle of an upper crossbeam of a rack; a middle fixed crossbeam is provided with a coupler; a ball screw is connected with a spindle of the servomotor and penetrates through the coupler to be meshed with a ball nut; the ball nut is fixed on a movable crossbeam by a cylindrical sleeve; two ends of the movable crossbeam move up and down along guide rails by sliding blocks to drive an upper die to move, a pressure sensor is arranged between the upper die and the movable crossbeam and used for detecting the forming pressure between the upper die and a lower die; a vertical guide rail is provided with a precise grating ruler for detecting and controlling the position of the upper die. The supersonic vibrating assistant plastic forming device is simple and reliable in structure and capable of being used for supersonic auxiliary forming machining of metal materials of copper and nickel and non-metallic materials such as resin and rubber and can realize higher machining precision.

Description

technical field [0001] The invention belongs to the technical field of plastic forming, and in particular relates to an auxiliary plastic forming device. Background technique [0002] Years of research have shown that ultrasonic vibration has a significant improvement effect on the plastic forming process. It has beneficial effects such as reducing the friction between the mold and the workpiece during processing, reducing the resistance of the forming process, and improving the forming quality. The existing relatively mature processes include ultrasonic cold-drawn wire and ultrasonic cold-drawn tube, and the processes of ultrasonic-assisted deep drawing and ultrasonic-assisted extrusion have also been studied in depth. The traditional ultrasonic-assisted plastic forming equipment has also developed relatively maturely, and can reliably introduce ultrasonic vibration into the plastic forming process to realize ultrasonic-assisted plastic forming. Two important processing pa...
