Title:
LIMITING ROTATING BIT APPARATUS HAVING VACUUMING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/057157
Kind Code:
A1
Abstract:
A limiting rotating bit apparatus having a vacuuming mechanism, comprising a cutter die (1), an intermediary plate (2), a bottom plate (3), a positioning disk (6), and a moving bit (7). The cutter die is mounted at the bottom of the intermediary plate via an L-shaped fixing element (11). The bottom plate is fixed on the intermediary plate via a screw. The positioning disk is mounted via a screw on the upper plate surface of the bottom plate. The moving bit is provided directly above the positioning disk. The moving bit comprises a Y-axis moving frame (71), an electric motor mounting plate base (72), and a rotating bit mounting frame (73). The limiting rotating bit apparatus, with scraps being sucked in via a small vacuuming hole (4) provided on the cutter die and on the intermediary plate, and then sucked away via a round suction hole (5) provided on the bottom plate and on the positioning plate, prevents dusts produced during punching from affecting the working environment and the normal operation of a mechanical limiting rotating bit.
