[0002] A square tube is a square tube that is generally a hollow structure. Many materials can be used to form a square tube. Currently, square tubes are mostly produced in two ways. One is to cold-bend the steel strip into a closed round tube through a multi-pass forming rack, and then high-frequency weld it, and then sizing it into a square tube or rectangular tube. The other is to directly cold-bend the steel strip into a square tube through a multi-pass forming rack, and then high-frequency weld it, and then extrude the steel strip so that the two sides of the steel strip are connected to each other to form a closed square. However, the current square extrusion device needs to be fully covered on top during the extrusion process. In traditional equipment, the corresponding upper roller mold needs to be replaced according to the size of the square tube produced, which wastes a lot of time in replacing the rollers, causing many inconveniences to production changes;

[0003] The existing square tube pressing machine requires workers to manually put round tubes into the square tube pressing machine one by one, which is inefficient and requires a lot of physical strength.
