The radiating fins with large-batch requirements are generally processed by adopting a stamping mode, but the conventional copper or aluminum belongs to soft materials and has strong plasticity, and the punched material sheet has serious arc-shaped corner collapse edges because the edges are extruded. In addition, since the heat sink is thick, a large punching force is generated during punching, and therefore, a large area of fracture lines are formed on the side wall of the heat sink. This surface quality does not meet the bonding process requirements.

In order to improve the above situation, the general method is to perform the stamping process by two steps, namely, rough stamping and fine stamping, and the existing fine stamping process is as follows: manually distinguishing the front side and the back side by visual observation, clamping the material sheet by tweezers, horizontally placing the material sheet in a cavity of a stamping die, then stepping down a punch to complete a punching time, cleaning waste materials in the cavity by compressed air, and repeating the steps. The finished web that falls under the die also needs to be collected at irregular intervals during the stamping process. The existing method has the problems that material sheets are not easy to put in place, waste is not thoroughly cleaned, a mold is easy to damage and the like, and when in production, both hands of workers work in the range of the movable sliding block of the punching machine, so that the workers easily feel tired after long-time repetitive work, great potential safety hazards exist, and the production efficiency is difficult to effectively improve.
