DEVICE FOR THERMAL STRAIGHTENING OF METAL PLATES

摘要

FIELD: machine building.SUBSTANCE: device for thermal straightening of metal plates contains flat support plates with holes arranged along contour, tightening devices secured in holes of the flat support plates and made out of the material with thermal-expansion coefficient exceeding the same of the material of the straightened metal plates. The flat support plates are made out of the material having lower specific heat capacity in comparison with the material used to manufacture the tightening devices. The tightening devices are made with central through holes for forced air blowing.EFFECT: increased accuracy of thermal straightening of metal plates.3 dwg
