Abstract

The utility model discloses a square pipe cut-off die, comprising a punch on an upper die holder and a female die on a lower die holder. The female die is horizontally provided with a first cavity suitable for a square pipe to pass through, and is longitudinally provided with a second cavity suitable for the punch to pass through, wherein the first cavity transversely penetrates through the second cavity. Due to the adoption of a hardware die mode to cut a square pipe, the punch longitudinally passes through the female die to cut off the square pipe which horizontally passes through the female die, so that the blanking size precision and the cut quality are guaranteed by the die. Harsh noises are avoided when an electric saw cuts and rubs metals, and odors which are generated by material combustion due to high-temperature friction are eliminated. Meanwhile, the production efficiency is significantly increased. Furthermore, the square pipe cut-off die is suitable for cutting iron square pipes, aluminum square pipes and stainless steel square pipes on a large scale, so as to reduce the production cost for enterprises.
