[0002] Die forging is a process method for producing forgings on a free forging equipment using a single-cavity die named die film. The die forging generally adopts free forging pre-forging blanking. Then, the final forming is performed in the die film. The die forging has accurate shape and high dimensional accuracy. Therefore, the die forging is often used for processing forgings in automobile manufacturing.

The utility model sets up the damping mechanism, the upper mold displacement drives the connecting plate to displace, the connecting plate displacement contacts the movable rod to drive the movable rod to displace, the damping spring deformation generates the elastic force to damp, the movable seat and the movable rod displacement drive the rotating disc to rotate, and at the same time, the friction block displacement contacts the outer wall of the rotating disc to generate the friction force as the resistance to damp, thereby damping when the upper mold and the lower mold are closed.

[0052] Further, after the controller connected with the infrared range finder 74 obtains the approximate position of the tire membrane, the controller controls the air cylinder 621 connected thereto to expand and contract, so that the forked telescopic connecting rod 622 is pushed to contract by the air cylinder 621, so that the second magnetic fluid dampers 623 at the inflection points of the forked telescopic connecting rod 622 are close to each other, thereby driving the second magnetic fluid dampers 623 to correspond to the position of the tire membrane, so as to damp according to the position of the tire membrane;

[0061] After the controller connected with the infrared distance sensor 74 obtains the approximate position of the tire membrane, the controller controls the cylinder 621 connected therewith to extend and retract, so as to drive the forked telescopic connecting rod 622 to retract by the cylinder 621, so that the second magnetic fluid damper 623 at the inflection point of the forked telescopic connecting rod 622 approaches each other, thereby driving the second magnetic fluid damper 623 to correspond to the position of the tire membrane and to damp according to the position of the tire membrane.

[0062] The rigidity of the second magnetic fluid damper 623 is changed by the second exciting coil 625 sleeved on the second mandrel 624, so that the controller adjusts the rigidity of the second magnetic fluid damper 623 corresponding to the tire membrane according to the tire membrane position, thereby adjusting the cushioning effect for the tire membrane. In the same way, the rigidity of the first magnetic fluid damper 611 is changed by the first exciting coil 613;
