Quick retooling dolly of press

The utility model relates to a quick retooling dolly of press, which comprises a vehicle rack, said frame bottom is equipped with the gyro wheel, and the frame upside is equipped with the die carrier guide rail, is equipped with the bearing gyro wheel of two rows of parallels between the die carrier guide rail perpendicularly, still be equipped with dolly actuating mechanism in the said frame, brake mechanism, die carrier push-pull institution, die carrier positioning mechanism and die carrier elevating system, dolly actuating mechanism is used for driving the dolly and walks on rather than the complex track, die carrier push-pull institution is used for drawing in the die carrier or release to the press workstation from the press workstation, and die carrier positioning mechanism is used for fixed die carrier position on the die carrier guide rail, thereby die carrier elevating system is used for going up and down the die carrier bottom to take turns the height that reduces the die carrier rather than the walking of contact, makes die carrier bottom surface and the contact of bearing gyro wheel to shift out the retooling dolly in the die carrier along bearing gyro wheel side direction. The utility model discloses can realize that large-scale heavy die carrier from the quick immigration of press workstation, shifts out and transports, improve retooling work efficiency, reduce retooling down time
