一、前言随着科学技术的发展,特别是航空、印刷、家用电器等工业的不断发展,对板带材的平直度要求越来越高。过去矫直板材几乎都是采用多辊式矫直机,或者是单张拉伸矫直机,其矫直效果均不理想。特别是对于薄带材和难变形金属更达不到要求。近年来发展了拉弯矫直的新型矫直设备,它是一种拉伸矫直与弯曲矫直的综合效果的设备。新矫 I. Introduction With the development of science and technology, especially the continuous development of aviation, printing, household appliances and other industries, the requirements for the flatness of the strip are getting higher and higher. Almost all of the past straightening plates used multi-roller straightening machine, or sheet stretching straightening machine, the straightening effect is not satisfactory. Especially for the thin strip and difficult to meet the metal less demanding. In recent years, the development of a new straightening and straightening straightening equipment, it is a tensile straightening and bending straightening the combined effect of equipment. New correction
