A circular cutting machine

Abstract

The present invention discloses a circular cutting machine, comprising a worktable with a punching hole on the worktable, a transverse rotating shaft on the worktable, a gear in the middle of the rotating shaft, a support frame on one side of the gear placed on the worktable, and a gear rack that moves up and down on the support frame. The gear rack meshes with the gear, and a punching rod above the punching hole is fixed below the gear rack; The shaft is equipped with a rotating ratchet, and the gear is equipped with a pawl that matches the ratchet. When the gear rotates counterclockwise, the ratchet does not move, and when the gear rotates clockwise, it drives the ratchet to rotate; The outer end of the ratchet wheel is fixed with a fixed ring, and the outer edge of the fixed ring is uniformly distributed with multiple telescopic rods. The outer end of the telescopic rods is hinged with compression blocks, which solves the problem of complicated round sheet stamping operations.
