The utility model relates to the technical field of steel punching calibration, in particular to a calibration structure for a steel punching device, which comprises a punching underframe, a steel plate and a calibration block. The device has the beneficial effects that a steel plate conveniently slides to the lower ends of the multiple sets of calibration blocks through the calibration slopes, when the steel plate slides downwards and makes contact with the limiting slopes, anti-shaking limiting blocks are pressed into anti-shaking jacking grooves, when the steel plate makes contact with the punching bottom frame, anti-shaking jacking springs jack the anti-shaking limiting blocks to stretch out of the anti-shaking jacking grooves to longitudinally limit the steel plate, and the steel plate is prevented from longitudinally shaking; a connecting plate is driven by a handle to be pulled outwards, so that a connecting rod is driven to pull an anti-shaking limiting block to enter the anti-shaking limiting block,
