Annealing clamping device for silicon steel iron core

The utility model relates to an annealing clamping device for a silicon steel iron core in the technical field of clamping. A shaping device is arranged on the inner wall of a control box; and a placing mechanism is arranged at the top of the second clamping plate. An air pump in the shaping device drives a telescopic rod to move, so that an upper pressing plate arranged at the bottom of a first clamping plate moves downwards, a second clamping plate drives a containing groove to move upwards, the upper pressing plate is pressed into the inner wall of the containing groove to conduct rectangular shaping on the wound iron core, and a first spring and a second spring are arranged in the pressing process to play a role in preventing shaking; the working efficiency is effectively improved, and the practicability is high; a starting motor in the placing mechanism drives a rotating shaft to rotate, the rotating shaft rotates to drive a gear to be meshed with a rack to drive a hollow lifting plate to move downwards,
