Description

Technical Field

[0001] The utility model relates to the field of signage punching, in particular to a precision punching device for signage processing. Background Art

[0002] In the early days of signboard manufacturing, manual punching was a common method. Craftsmen used simple tools to punch holes in signboards. The dimensional accuracy of manual punching was also difficult to control. Due to uneven force, the punch could tilt during the punching process, resulting in irregular holes with varying diameters.

[0003] With the development of sign manufacturing technology, die punching has become widely used. Die punching uses a prefabricated punching die to punch holes in the sign material under the action of a press. This method improves punching accuracy and efficiency to a certain extent. However, die punching suffers from a lack of flexibility, requiring die replacement after punching. Traditional punching methods are inefficient and cannot meet the requirements of large-scale production. Therefore, a device that can punch quickly and accurately is needed. Utility Model Content
