Description

Technical Field

[0001] The utility model relates to a fin press pin machine, specifically a pneumatic press pin machine. Background Technique

[0002] Pressing pins on the fin is a way to fix the fin, which is used to ensure close contact between the fin and the heat source, so as to effectively conduct heat from the heat source to the fin. The fin used on the transformer needs to be installed with pins. The press pins are usually made of metal and are in the shape of slender needles. By inserting them into the gap between the fin and the heat source and then applying a certain pressure, the fin can be closely attached to the heat source. The use of press pins can improve the heat dissipation efficiency and reduce the heat transfer resistance between the heat source and the fin. At the same time, the press pins can also ensure that the fin maintains a stable position during long-term use and avoid poor heat dissipation caused by vibration or other factors. When the existing pneumatic press pin machine is working, generally, the pins are pressed into the fin by a striker. Since the striker is prone to surface wear after long-term collision with the pins during use, it needs to be replaced regularly. When the existing pins are installed, they are generally fixed inside the clamping seat by bolts to clamp the striker. When installing the bolts, one hand needs to position between the striker and the clamping seat, and the other hand needs to install the bolts. Under the action of gravity, the hand support is usually unstable, resulting in an incorrect installation angle of the striker. Especially for a pneumatic press pin machine that simultaneously punches and docks two pins, it is more likely to have a large installation difficulty and the docking position between the striker and the clamping seat is offset, which is not conducive to improving the speed of replacing the striker and the convenience of installation.
