Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of refrigerator processing, and in particular relates to a trimming device for a refrigerator back plate. Background Art
[0002] High-end refrigerator products are often equipped with a detachable metal refrigerator back panel. Compared with plastic refrigerator back panels, metal refrigerator back panels have better heat dissipation performance and durability, and also help to improve the refrigeration efficiency of the refrigerator; the metal refrigerator back panel needs to go through processes such as cutting, stamping, spot welding and trimming before it can be used for the assembly of the entire refrigerator. In this process, trimming is an extremely important process. The edges of metal plates after cutting and stamping often have very sharp burrs or flash. If these burrs or flash are not processed, on the one hand, it will affect the subsequent assembly accuracy and the aesthetic effect of the metal refrigerator back panel; on the other hand, the sharp burrs or flash are like blades, which can easily scratch production employees, thereby causing production safety accidents and posing serious safety hazards; therefore, a processing device for trimming the edges of metal refrigerator back panels is needed.
