[0002] The straightening machine used in large steel structure processing is a device specially used to correct metal plates or profiles. Its main purpose is to accurately correct steel structures to meet the requirements of engineering quality. This type of straightening machine usually has a large working range and strong correction ability to meet the processing needs of large steel structures. When using the straightening machine, since the thickness of the plate to be corrected each time is not necessarily fixed, it is easy for some plates to not fit in during correction. When the plate is thin, the number of correction rollers needs to be increased to avoid shaking and shaking of the plate during continuous correction. However, if a large number of correction rollers are used for each plate during correction, it will affect the working cost of the entire equipment. Utility Model Content
