Description

Technical Field

[0001] The utility model belongs to the technical field of television back panel processing devices, in particular to a television back panel punching device. Background Art

[0002] The TV back panel is an important part of the TV structure. It is usually located at the back of the TV and plays a role in protecting internal electronic components, providing structural support and assisting heat dissipation. The production and processing of TV back panels involves multiple processes. Stamping is an important process for its molding and manufacturing. In the production and processing, it is usually produced and processed with the help of corresponding stamping devices. Before stamping the raw materials of the TV back panel, it needs to be clamped and fixed to prevent the raw materials of the TV back panel from being offset due to external forces during the stamping process, causing processing deviations or even direct scrapping of the raw materials. However, most of the common stamping devices for TV back panels clamp and fix the TV back panel through a manually operated clamping mechanism. During the clamping operation, the TV back panel may be damaged due to excessive clamping force due to improper operation, or the clamping force may be insufficient, resulting in offset during the stamping process. In addition, the clamping and unclamping process is relatively cumbersome, which is not conducive to improving the overall processing efficiency.

[0003] In summary, the clamping and fixing operation of the TV back panel punching device is inconvenient and there are some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
