Currently, during the production of punching dies for refrigerator liner holes, hole deviation often occurs, exceeding the design tolerance. In particular, offset guide rail holes not only cause drawers to become loose and affect user usability, but also cause unevenness after assembly, affecting the appearance.
[0003] First of all, the refrigerator lining is formed by vacuum forming, which is affected by changes in process parameters, ambient temperature, sheet material parameters, cooling time and other parameters. The refrigerator lining is prone to problems such as uneven thickness, different shrinkage sizes due to heat and cold, and structural deformation, which directly affect the punching accuracy of the refrigerator lining.
