[0050] Use of this example:
[0051] (1) Place the solid tire 5 on the workbench 8 , and perform rough positioning of the solid tire 5 through the positioning member 10 .
[0052] (2) Place the core expanding mold 4 in the mounting hole of the solid tire 5 of the solid tire 5 .
[0053] (3) Place the hub of the wheel 3 in the escape hole B403 of the core expanding die 4 , and place the rim of the wheel 3 in the ring groove 401 of the core expanding die 4 .
[0054] (4) The lifting device of the lifting and lowering head assembly 2 is actuated by the controller 6, the pressing head 218 is lowered, and the lowering of the pressing head 218 is divided into four stages:
[0055] The first stage: the buffer heads of the three hydraulic buffers 214 are in contact with the bearing ring table 402 of the core expanding die 4. During the descending process of the indenter 218, the buffer heads of the three hydraulic buffers 214 are slowly moved toward the indenter 218 The inside of the core is pressed in, so that the core expanding die 4 is gradually adjusted to a horizontal state;
[0056] The second stage: the pressure head 218 continues to descend, the buffer heads of the three hydraulic buffers 214 are all pressed into the inside of the pressure head 218, the pressure head 218 contacts the bearing ring platform 402, and applies pressure to the bearing ring platform 402, and the pressure rises. The core mold 4 descends under the action of pressure, so that the mounting hole of the solid tire 5 expands, and the wheel 3 naturally descends with the core mold 4;
[0057] The third stage: the indenter 218 continues to descend, the core expansion mold 4 is gradually pressed out of the solid tire 5, and the backstop 213 contacts the spokes of the wheel 3 to apply pressure to keep the wheel 3 in a horizontal state;
[0058] The fourth stage: the pressure head 218 continues to descend. When the pressure head 218 falls to the lower limit position, the switch sensing block 210 senses the lower limit switch 208, and the controller 6 controls the lifting device of the lifting and lowering head assembly 2 to stop descending; the hydraulic buffer 214 The natural rebound of the buffer head makes the core expansion mold 4 and the solid tire 5 separate from each other.
[0059] (5) The lifting device of the lifting and lowering ram assembly 2 is actuated by the controller 6, the ram rises, and when the ram rises to the upper limit, the switch sensing block 210 senses the upper limit switch 211, and the controller 6 controls the lifting and lowering of the ram. The lifting device of module 2 stops rising.
[0060] For the assembly of solid tires 5 and wheels 3 of different specifications, it is only necessary to replace the core expanding mold 4 and the indenter 218 with a suitable size.
