Description

technical field

[0001] The invention relates to a variable roller distance straightening machine used for straightening plate and strip in metallurgical machinery or other industries. Background technique

[0002] At present, the straightening machines for plate and strip at home and abroad, especially medium and thick steel plates (thickness 4-60mm) are constant roll distance or double constant roll distance straightening machines, and have not found the same principle and structure as the present invention. Or the literature report of the similar sheet and strip material variable roll distance straightening machine. The disadvantage of the constant roller distance straightening machine is that the roller distance cannot change with the thickness and strength of the straightening plate and strip. In this way, either the strength of the roller system and the transmission device is weak, or the thickness and strength of the straightening plate and strip are limited. , The st...
