Grinding wheel blank pressing floating type die pressing seat

The utility model discloses a grinding wheel blank pressing floating type die pressing seat which comprises a base plate, the outer surface of the base plate is fixedly connected with a limiting flange, the inner wall of the limiting flange is connected with an elastic pressing rod in a sliding mode, and a retarding mechanism is arranged below the elastic pressing rod. Through cooperation of a first spring, a second spring, an I-shaped plate, a convex groove flange, a limiting plate, an elastic pressing rod, supporting rods and a stabilizing frame, when the elastic pressing rod moves downwards, the four supporting rods can push the I-shaped plate to extrude the second spring, when force from the upper portion of a lower die disappears, the second spring can push the I-shaped plate, and the convex groove flange stops moving when making contact with the limiting plate; and after resetting, the spring I mainly bears the weight, and the spring II secondarily bears the weight, so that the performance of the spring
