Description

Technical Field

[0001] This utility model relates to the field of cabinet panel processing technology, and in particular to a punching die for cabinet panels. Background Technology

[0002] In the production process of furniture cabinet panels, operations such as cutting, punching, and forming of the panels are usually involved. These operations often require the use of stamping dies and punches. The punch is the core component of the punching operation, used to quickly and accurately punch holes of the required shape and size on the panel, such as mounting holes, decorative holes, and connecting holes.

[0003] According to the patent document with publication number CN220562017U, the patent document describes a design that uses an upper template consisting of a moving template, a mounting plate, and a punch. The moving template is positioned on both sides and positioned on the punch press by means of a mounting groove and a pressure block. When the punch needs to be replaced, the mounting plate can be removed from the mounting groove by twisting the adjusting rod, and then the punch connected to the mounting plate by threads can be replaced. This eliminates the need to remove the entire upper template, simplifying the replacement of the mold punch, reducing workload, and improving the efficiency of punch replacement.

[0004] According to the patent document, during the stamping process, debris or impurities may accumulate on the surface of the punch. If they are not cleaned in time and stamped again, scratches will be caused on the surface of the punch, affecting the quality of the subsequent stamped parts. In addition, high-frequency stamping operations will cause the punch to generate a lot of heat in a short period of time, which cannot be dissipated in time. Overheating may cause deformation of the surface of the stamped parts. Utility Model Content
