As a high-precision equipment, standardized operation and daily maintenance are the key for stretch bending machines. During operation, it is necessary to accurately set the tensile force and bending angle according to the profile material and specifications to avoid profile fracture caused by excessive tensile force and wrinkling caused by insufficient tensile force; ensure that the profile is firmly fixed during loading to prevent sliding and deviation. In terms of daily maintenance, regularly check the stretching mechanism, fixtures and hydraulic system, timely add lubricating oil, and clean the iron chips and debris on the equipment surface and fixtures; regularly calibrate the equipment precision, and timely replace and fasten worn fixtures and loose components to avoid affecting the processing precision and equipment service life.
