5. An assembling and forming method of a refrigerator base, which is characterized in that the assembling and forming method is applied to the refrigerator base integrated assembling and forming device according to any one of claims 1-4, and the assembling and forming method comprises the following steps:
Step one, material preparation: the bottom plate is fixedly arranged on a third layer plate (23), and the roller is arranged in an arc-shaped groove (221) on a second layer plate (22);
Step two, one-section lamination: the pressing control assembly (40) controls the distance between the second layer plate (22) and the first layer plate (21) to be unchanged, the top die (10) is driven to press downwards, the pressing head (12) continuously presses after contacting the bottom plate to enable the third layer plate (23) to be close to the second layer plate (22) until the third layer plate (23) moves to the limit position, the roller enters between two wing plates on the bottom plate, and the mounting hole of the roller is coaxial with the mounting hole on the wing plate;
Step three, pin assembly: the pin is assembled into the mounting holes on the roller and the wing plate;
Step four, two-section lamination: the pressing control assembly (40) releases the control of the distance between the second layer plate (22) and the first layer plate (21), drives the top die (10) to continuously press down, and enables the second layer plate (22) and the third layer plate (23) to be close to the first layer plate (21) at the same time until the second layer plate (22) moves to the limit position, and the flanging block (211) contacts the bendable part on the bottom plate and ejects and bends the bendable part to the side of the pin to form limit, so that the assembly forming of the refrigerator base is completed;
