The invention belongs to the technical field of
punching machining and particularly discloses a
spoke air hole
machining die. The
spoke air hole
machining die comprises an upper die and a lower die. The upper die comprises an upper die plate, a transmission rod and a punch. Pawls are hinged to the transmission rod. The lower die comprises a lower die plate, a rack, a rotating shaft and a
punching block. The rotating shaft is rotationally connected to the rack, and the rotating shaft is in
interference fit with the rack. A positioning plate and a
ratchet wheel are fixed to the rotating shaft. A through hole matched with a
spoke bolt hole is formed in the positioning plate. A cavity and a sliding groove communicating with the cavity are formed in the upper portion of the
punching block. A
magnet protruding block is connected to the sliding groove in a sliding manner, a punching hole is formed in the
magnet protruding block, and a coil located below the
magnet protruding block is arranged in the punching block. A controller and a speed sensor are installed on the rack, and the speed sensor and the coil are electrically connected with the controller. The spoke air hole machining die is adopted for machining a spoke air hole, after
hole punching is completed, a spoke can be driven to rotate, punching continuity is ensured, and in addition, friction between the spoke and the magnet protruding block in the spoke rotating process can be avoided.
