Some key points for operating the shearing machine. A shearing machine is a widely used cutting mechanical equipment in industrial processing, which can cut steel plate materials of various thicknesses. The commonly used shearing machines are divided into three types: flat shearing, rolling shearing, and vibration shearing. Flat cutting machines are widely used. Cutting machines with a thickness less than 10mm are mostly mechanically driven, while those with a thickness greater than 10mm are hydraulically driven. Generally, single or continuous metal cutting is carried out using foot pedals or button controls. When operating the shearing machine, attention should be paid to:

　　(1) Before starting work, carefully check whether all parts of the shearing machine are normal, whether the electrical equipment is intact, and whether the lubrication system is unobstructed; Remove tools, measuring tools, and other debris from the countertop and its surroundings, as well as corner waste.

　　(2) Do not operate the shearing machine alone. It should be coordinated by 2-3 people for feeding, controlling dimensional accuracy, and material retrieval, and it should be determined that one person is responsible for unified command.

　　(3) Adjust the gap between the scissors of the shearing machine according to the specified thickness of the shearing plate. It is not allowed to cut two different specifications and materials of sheet metal at the same time; Do not stack or cut materials. The surface of the cut sheet material should be flat, and it is not allowed to cut narrow sheets that cannot be compressed tightly.

　　(4) Protective covers must be installed on the moving parts such as belts, flywheels, gears, and shafts of the shearing machine.

　　(5) The operator of the shearing machine should maintain a distance of at least 200mm from the cutting edge and keep their fingers away from the clamping device when feeding. The protective fence installed on the trigger cannot block the operator's eyes and prevent them from seeing the cutting area. The waste generated after homework has sharp edges and corners, and the operator of the shearing machine should promptly remove them to prevent the possibility of being stabbed or cut.
