After shearing, the shearing machine should be able to ensure the straightness and parallelism requirements of the sheared sheet material, and minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the workbench. Supporting balls are installed on the worktable so that the sheet material will not be scratched when sliding on it. The back gauge is used for positioning the plate, and the position is adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during shearing. The guardrail is a safety device to prevent work-related accidents. The return journey generally relies on nitrogen, which is fast and has little impact. Need to blank before stamping. Blanking refers to the process of cutting sheets or coils into strips, strips or blocks before stamping production. The commonly used equipment for cutting sheets is a shearing machine. With the help of the moving upper blade and the fixed lower blade, the shearing machine uses a reasonable blade gap to apply shearing force to metal sheets of various thicknesses to separate the sheets into the required size.
How to use the shearing machine: adjust the gap of the blade according to the thickness of the material to be cut; adjust the profiling or fixture according to the width of the material to be cut; make 1-3 idle strokes before the shearing machine is operated, and it can be implemented after normal Cut work. If the machine is found to be operating abnormally during use, immediately cut off the power supply and shut down for inspection. When adjusting the machine tool, you must cut off the power supply, and pay attention to the safety of your hands when moving the workpiece. All parts of the shearing machine should be kept lubricated frequently. The operator should fill the lubricating oil once every shift, and the mechanics should fill the rolling bearing part with the lubricating oil once every six months.
