Here is a step-by-step method for adjusting the cutting straightness of NC hydraulic shears:
Method of use:
To achieve optimal results when using the NC hydraulic shearing machine, it is necessary to make a few adjustments. Firstly, adjust the blade gap based on the thickness of the plate being cut. Secondly, adjust the profile modeling and clamping according to the width of the material being cut. Prior to operating the machine, run it empty for 1-3 times and confirm that everything is functioning properly before beginning to cut.
After the cutting process, ensure that the surface of the cut is straight and parallel, with minimal distortion of the plate to obtain high-quality workpieces. The upper blade of the CNC shearing machine should be fixed on the tool holder, and the lower blade should be fixed on the working table. The working table should be equipped with a ball carrier to prevent scratches on the sheet when sliding it.
For sheet metal positioning, the rear stop should be used and its position adjusted by the motor. The hold-down cylinder should be used to press the sheet, preventing it from moving during shearing. A guard is also installed as a safety device to prevent accidents. The machine should return generally by nitrogen, ensuring fast and small impacts.
The NC hydraulic shearing machine is suitable for cutting a variety of materials, including steel, copper, aluminum, and non-metallic sheets with thickness ratings, provided there are no hard marks, welding slag, entrapped slag, welding seams, and the sheet thickness is not exceeded.
