Technical Field

[0001] The utility model relates to the technical field of heat sink processing, in particular to a double-station stamping device for heat sinks. Background Technique

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze into plate-shaped, sheet-shaped, multi-sheet-shaped, etc. For example, a CPU central processing unit in a computer needs to use a quite large heat sink, and power tubes, line tubes in a TV set, and power amplifier tubes in a power amplifier all need to use heat sinks. Generally, a layer of thermal grease needs to be applied on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink.

[0003] During the stamping process of the heat sink, the plate is stamped into the forming die through the closing of the stamping die and the forming die. After completion, it is necessary to manually take out the stamped heat sink. Since the existing stamping devices are usually single-station, the time consumed for placing the plate and taking out the heat sink affects the production effect of the heat sink. Therefore, a double-station stamping device for heat sinks is needed to meet the requirements. Summary of the Utility Model
