Technical Field
[0001] The utility model relates to the technical field of processing heat sinks, in particular to a heat sink punching die. Background Art
[0002] Heat sinks are mostly made of aluminum alloy, brass or bronze in the shape of plates, sheets or multiple sheets. The teeth on the heat sink are used to conduct heat to achieve the heat dissipation effect on the object. Heat sinks are a device that dissipates heat from heat-prone electronic components in electrical appliances. They are mostly made of aluminum alloy, brass or bronze through punching machines and are punched into plates, sheets, multiple sheets, etc.
