Description

Technical Field

[0001] This utility model relates to the field of shell bending technology, specifically a shell bending and trimming machine. Background Technology

[0002] Metal casings are widely used as outer shells in various electrical components. During casing processing, they are first cut, then bent by a bending machine to form a fixed shape. After shaping, the edges need to be trimmed to avoid excessive sharpness, thus requiring bending and trimming equipment. However, traditional bending equipment is inconvenient for fixing the casing during bending and cannot trim the edges promptly. Therefore, we provide a casing bending and trimming machine.
