The invention discloses a single-point
longitudinal vibration controllable progressive forming
system for a
metal plate. The main shaft of the single-point
longitudinal vibration controllable progressive forming
system for the
metal plate is installed on a rack; a
force sensor is installed on the shaft end of the main shaft; a vibration
signal generator is connected with a
vibration exciter; the
vibration exciter is installed below the
force sensor; a tool head is connected with the
vibration exciter via a connecting rod; a
workbench is installed just below the main shaft; the input end of a parameter controller is connected with the
force sensor; and the output end of the parameter controller is respectively connected with the vibration frequency and
amplitude control port of the vibration
exciter as well as the X-shaft driving
motor control port and the Y-shaft driving
motor control port of the
workbench. A single-point
longitudinal vibration plasticity forming condition of the plate material is established by combining a forming technology parameter, a vibration mode parameter and a
forming force parameter, and the parameter controller is used for monitoring and regulating the forming technology parameter and the vibration mode parameter in real time according to the plate material forming technology state and the vibration
plasticity forming condition. The single-point longitudinal vibration controllable progressive forming
system for the
metal plate, which is disclosed by the invention, has the beneficial effects that the technical defects of single-point progressive forming can be overcome, the technology parameter and the vibration mode parameter can be monitored and regulated in real time according to the plate material vibration
plasticity forming condition in the forming process, and efficient and precise progressive forming of the metal plate material can be realized.
