The invention discloses a mechanical double
energy storage impact mechanism and a mechanical double
energy storage impact method. The mechanism comprises a frame, a rotating shaft is arranged on the frame, the rotating shaft is fixedly connected with a swinging arm, the swinging arm is connected with a hammer head, a
torsion spring is arranged coaxial with the rotating shaft, the swinging arm is fixedly connect to one end of the
torsion spring, and the other end of the
torsion spring is fixed on the frame. An electric driving mechanism and a first
electromagnet are arranged on the frame, the first
electromagnet is connected with a drag hook, a gear
clutch is arranged on the electric driving mechanism, and a lever is movably connected to the frame and movably matched with the drag hook; and a second
electromagnet is arranged on the frame through a mounting arm. The mechanism has two
energy storage links, namely deformation energy storage of the torsion spring and elastic bending energystorage of the swinging arm, so that the contact stress during impacting can be effectively reduced and the working surface of a workpiece is well protected. By using the mechanism and the method, conventional heavy manual hammering can be replaced, and the labor intensity is lightened; and the mechanism can also be used for replacing the conventional starting pneumatic striker in the
powder conveying process to prevent blockage.
