Friction welding cutter

The utility model provides a friction welding cutter which comprises a cutter body, a friction welding cutter head is further arranged on the cutter body, one end of the friction welding cutter head is connected with the cutter body and extends in the direction away from the cutter body, and a heat dissipation structure is arranged on the cutter body. And a mounting part for fixing the heat dissipation structure is arranged on the cutter body. A product is processed through the friction welding tool bit of the friction welding tool, heat dissipation is conducted on the tool body through the heat dissipation structure on the tool, and it is avoided that a large amount of heat is accumulated on the tool body. 本实用新型提出一种摩擦焊刀具，包括刀具本体，在所述刀具本体上还设有摩擦焊刀头，所述摩擦焊刀头一端与所述刀具本体连接，且向远离所述刀具本体的方向延伸设置，所述刀具本体上设有散热结构，在所述刀具本体上设有用于固定所述散热结构的安装部。通过所述摩擦焊刀具的摩擦焊刀头对产品进行处理，并通过所述刀具上的散热结构对刀具本体进行散热，避免在刀具本体上积聚大量热量。
