Abstract

The invention relates to the technical field of machining and manufacturing, in particular to a method and device for machining strip steel. The method comprises the steps that the effective length range of the strip steel is determined based on the first single side shearing amount and the preset same plate difference allowance of the strip steel; the height tolerance of a stator and a rotor is determined within the effective length range; and sheet adding or reducing treatment is carried out on the stator and the rotor based on the height allowance and the height tolerance of the stator and the rotor. Whether sheet adding or reducing treatment needs to be carried out on a certain position or not can be accurately determined, and therefore the position subjected to sheet adding or reducing treatment is accurately positioned so that abnormal parts of cutting sheets in the strip steel can be precisely cut off, the phenomenon that a large number of cutting sheets are generated by blind sheet adding or reducing treatment is avoided, and abnormal steel rolls in the strip steel are prevented from flowing into client sites.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and manufacturing, in particular to a method and device for processing strip steel. Background technique [0002] For modern electrical steel lamination high-speed presses, it is often necessary to set strict tolerance standards for stator and rotor dimensions. In the actual processing and production of punching sheets and laminations, if the dimensional accuracy of electrical steel materials fluctuates, there will be large thickness fluctuations in the middle of the strip steel, and the actual dimensions of the stator and rotor will exceed the set standards. Therefore, it is necessary to perform addition or subtraction processing. [0003] However, the existing technology cannot accurately locate the processing position of adding or subtracting slices. In order to make the actual size of the stator and rotor meet the set standard, adding or subtracting slices is often carried out b...
