Description

Technical Field

[0001] The present invention relates to the technical field of steel drum dismantling, and in particular to a drum cutting machine and a drum dismantling method for dismantling steel drums. Background Art

[0002] Existing barrel cutters used to dismantle scrap steel drums require manual clamping and visual inspection of the weld seam during the cutting process. This lacks stability and control over the barrel's rotational precision, making the cutting process inconvenient and impacting both efficiency and quality. The further the cutting position is from the weld seam, the lower the utilization rate of the subsequent recycled steel plate. Furthermore, this negatively impacts the leveling of the V- and W-ribs and corrugations on the barrel body after cutting, as well as the paint stripping process. After cutting the barrel body, existing barrel cutters require manual removal of the upper and lower barrel covers, impacting efficiency and posing a safety hazard when reaching inside the equipment. Summary of the Invention

[0003] The present invention aims to develop an automated steel drum cutting machine that can automatically identify incoming materials and perform barrel clamping, cutting, leveling, and automatic lid removal. The machine, used for disassembling steel drums, comprises a barrel cutting mechanism comprising a frame, a hydraulic cylinder, a horizontal slide rail, a tool handle, a broach, a fixing rod, a horizontal mounting rod, a lid cutting knife, a gear plate, a drive motor, a transmission shaft, and a transmission gear. During use, a loading mechanism pushes the barrel into the working position of the barrel cutting machine, and a barrel clamping device clamps the steel drum to be cut and disassembled inside the frame. A sensor senses the working position of the steel drum progress device, automatically clamps the steel drum, completes weld seam positioning, lowers the broach, cuts the barrel body and upper and lower lids, flattens the barrel body, and removes the lid. The entire operation process requires no manual labor and is stable and easy to operate. After the barrel is cut, the barrel surface will be subjected to destructive pre-treatment by leveling rollers to destroy the paint layer on the barrel surface, making it easier for the subsequent use of paint stripping solvents to quickly corrode the paint layer for rapid paint removal. This helps improve the efficiency and quality of the paint stripping process, and further improves the efficiency of the recycling and disassembly of scrap steel barrels.
