Description
Technical Field
[0001] This utility model relates to the field of keyboard processing technology, specifically a multi-station punching device for keyboard shells. Background Technology
[0002] Keyboard casing punching involves using a mold and a punch to precisely punch holes such as heat dissipation vents and mounting holes into the keyboard casing. The process includes three steps: positioning, punching, and unloading. The punch is driven by hydraulic, pneumatic, or mechanical power, and the multi-station design can simultaneously complete the processing of different hole types, making it suitable for efficient mass production.
[0003] For example, the announcement number CN208944947U is named Multi-station punching device for metal material processing. The device includes a worktable, a bidirectional sliding door is installed on the front surface of the worktable, and a punching plate is installed on the upper end of the worktable. Support frames are fixedly installed at the corners of the upper surface of the punching plate. The metal material to be processed can be fixed by a robot arm to prevent the metal material from moving during processing.
[0004] Since keyboard shells typically have different holes on the top and sides, and the aforementioned devices can only punch holes on the surface, it is not convenient to punch holes on the sides. This would require changing the structure and mold, and even transferring materials, which is quite inconvenient. Therefore, we proposed a multi-station punching device for keyboard shells to solve the problems mentioned above. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) By setting fixed seats on both sides of the processing table, a side punch is set on the inner side of the fixed seat, and a hydraulic cylinder is set on the outer side to drive the side punch to extend and retract. When the keyboard shell is fixed inside the limiting groove, the side punch is driven by the hydraulic cylinder to punch the side of the keyboard shell surface. A top plate is set at the upper end of the processing table, and a punching plate is set at the bottom of the top plate to punch the upper surface of the keyboard shell, thereby forming multi-station punching, reducing the keyboard transfer time, and realizing automated continuous processing.
