The coil is placed on the placement rack, and the end of the coil is pressed into the leveling roller group. The leveling roller group rotates and pulls the coil into it, continuously rolling it to make it flat. The leveled steel plate enters the knife rack part and is cut by the knife group to form a steel plate. There are some functional deficiencies in actual use and there is room for improvement. For example, during the leveling process, if the stress of the steel plate itself is not completely eliminated, there will still be surface undulations after leveling, which can usually only be discovered during the final quality inspection of the finished plate. Subsequent remediation requires involving multiple steel plates, which is more troublesome to operate and does not have the function of monitoring the flatness of the steel plate.

[0004] Now, a new type of bending, straightening and shearing equipment for steel coil processing is proposed to solve the above problems. Utility Model Content
