Preferably, the outlet of the steel tube of the flattening device is opposite to the inlet of the forming device. The steel pipe pressed into an oval shape by the roller enters the forming device for further processing.

Preferably, a plurality of mounting shafts are fixed in the mounting groove, the positive pressure wheel is longitudinally mounted through the mounting shafts, the lateral pressure wheel is transversely mounted through the mounting shafts, and the positive pressure wheel and the lateral pressure wheel both rotate around the respective mounting shafts. The width and the height of the steel pipe are controlled by adjusting the positions of the positive pinch roller and the side pinch rollers, the horizontal distance between the bottom ends of the two side pinch rollers at the left side and the right side is the width of the bottom edge of the rectangular steel pipe, and the vertical distance between the bottom end of the positive pinch roller at the upper side and the top of the positive pinch roller at the lower side is the side height of the rectangular steel pipe. The steel pipe with the circular cross section can only be used for processing a square steel pipe, if the steel pipe is forcibly processed into the rectangular steel pipe, the steel pipe is twisted, and the asymmetric conditions that the heights of two sides of the rectangular steel pipe are different and the upper width and the lower width are different occur, so that the oval steel pipe is used, and the upper, lower and left-right symmetry can be kept by the subsequent processing because the heights and the widths are changed in one step.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the cross-section is oval-shaped steel pipe through flattening device formation oval-shaped steel pipe for circular shape steel pipe, oval-shaped steel pipe obtains the steel pipe of rectangle after the forming device shaping, and the steel pipe rule symmetry that obtains, and the shape accords with the trade requirement, compares the steel sheet of prior art and bends or the steel pipe of the rectangle that the concatenation obtained, because adopt direct forming's mode, intensity is bigger, because the raw materials is circular steel pipe, need not plus other processes and raw materials outside having gone out the equipment of assembly line, consequently manufacturing cost is lower.
