Abstract
This utility model discloses an open double-crankshaft overhead punch press, including a frame, a drive device and a worktable mounted on the frame. An upper die and a lower die are respectively mounted on the drive device and the worktable. A chip box is located between the worktable and the lower die. A filter plate and a collection box are sequentially arranged inside the chip box. A scraper is mounted on the filter plate, contacting the surface of the filter plate. A rotating mechanism is mounted on the filter plate, including a mounting frame, a rotating shaft, and a fixing sleeve. The mounting frame is fixed to the filter plate, the rotating shaft is rotatably mounted on the mounting frame, the fixing sleeve is fixed outside the rotating shaft, and the scraper is fixed outside the fixing sleeve. The rotating mechanism has two locations, located on both sides of the filter plate. One rotating shaft is connected to a motor, and the two rotating shafts are connected by a connecting rod. The arrangement of the filter plate and the scraper ensures that chips are evenly pushed into the chip box, preventing chips from accumulating below the sheet metal and affecting the punching and forming of the sheet metal.
