[0001] The utility model relates to the field of metal processing, and in particular to a metal plate cutting device. Background Art

[0002] The automotive condenser production process involves multiple steps to ensure quality and functionality. The condenser's primary components include aluminum fins, copper tubes, and header plates. Die stamping is commonly used in the production of metal fins. A thin sheet of metal passes through a designed die and is pressed into a specific fin shape under pressure. The fins are then cut into individual pieces. This method efficiently produces fins with high precision and consistency.

[0003] When processing metal fins, the metal sheet cutting device of the prior art directly transfers the die-cut and stamped fins to the cutting device for secondary cutting and trimming to form a single piece. During long-term use, the cutter needs to be regularly inspected or replaced, but the existing cutter installation mostly uses a large number of bolts for fastening, and disassembly and replacement of the cutter are relatively troublesome, which wastes time and affects the efficiency of processing the fin plate.
