The invention discloses an automatic steel strip
machining method. The method comprises the steps that (1), a forming
machine machines the nth coil of steel strip, a material
tail detection switch detects the material
tail of the nth coil of steel strip, the forming
machine stops, wherein n is larger than or equal to 1; (2), the steel strip is stopped at the material
tail cutting point position ofthe nth coil of steel strip, and a shearing mechanism is started to
cut off the material tail of the nth coil of steel strip; (3), the (n+1)th coil of steel strip is conveyed to the material head
cutting point position, and the shearing mechanism is started to
cut off the material head of the (n+1)th coil of steel strip; (4), the
cutting surface of the nth coil of steel strip and the cutting surface of the (n+1)th coil of steel strip are spliced and aligned; (5), a
welding machine is started to weld a joint formed by the cutting surface of the nth coil of steel strip and the cutting surface of the (n+1)th coil of steel strip so as to weld the nth coil of steel strip and the (n+1)th coil of steel strip into a whole; and (6), the forming machine is started again, and the nth coil of steel strip moves forwards in the
production line direction to drive the (n+1)th coil of steel strip to enter the forming machine to be machined.
