Description

Technical Field

[0001] The utility model relates to a shell plate forming device for refrigerator production, belonging to the technical field of plate bending equipment. Background Art

[0002] With the continuous development of science and technology, there are more and more types of refrigerators. Refrigerators have become essential items in daily production and life. In order to make the exterior of the refrigerator shell more firm and not easily damaged, and to extend the service life of the refrigerator shell, an outer shell plate is installed on the exterior of the refrigerator shell (refer to Figure 9 ). The process method adopted in the industry is stamping processing with a metal mold.

[0003] The width dimension of the outer shell plate changes with the different volumes of the refrigerator. Correspondingly, stamping molds with different width dimensions are required, which results in the need for multiple molds during processing. The price of the molds is high, leading to an increase in the cost of the enterprise;

[0004] Another disadvantage is that the time consumed for mold installation and debugging when changing products of different specifications is also a cost;

[0005] Due to the above deficiencies, our enterprise provides a shell plate forming device suitable for different widths of refrigerator shells. Content of the Utility Model
