[0073] In one embodiment, please refer to Figure 8 The die changing trolley 4 further comprises a bogie 415 mounted on the trolley frame 41 and a steering wheel 416 rotatably mounted on the bogie 415. In this structure, the steering operation of the die changing trolley 4 can be realized through the cooperation of the bogie 415 and the steering wheel 416. Through the cooperation between the steering wheel 416 and the plurality of rollers 411, the reliability of the movement of the die changing trolley 4 can be improved.

[0074] The specific die changing steps of the water-cooled sizing machine provided in the present application are as follows:

[0075] 1. The die changing trolley 4 is pushed into the space between the two limiting blocks 34, and is connected and fixed with the rack 3 through the fixing member 44;

[0076] 2. The die assembly 2 hung on the abutting support 43 is abutted into the support frame 1 through the abutting of the abutting support 43, and the first locking member 21 on the die assembly 2 is aligned with the second locking member 11 on the support frame 1;

[0077] 3. The second locking member 11 is driven to descend by the driving unit 12, the sliding seat 112 is driven to move by the first power unit 113, and the sliding seat 112 is locked with the clamping seat 212, so as to realize the connection between the first locking member 21 and the second locking member 11;

[0078] 4. The pressing seat 132 is driven to rotate by the second power unit 133 through the connecting member 134, so as to realize the pressing of the bottom of the die assembly 2 through the cooperation between the pressing seat 132 and the groove 222 on the mounting seat 221, and the installation and fixation of the die assembly 2 are completed;

[0079] 5. The die assembly 2 is electrically connected with the water-cooled sizing machine.

[0080] It should be understood that the sequence of the steps in the above-mentioned embodiments does not mean the order of execution, and the execution order of the processes should be determined according to the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0081] The above only describes optional embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
