Abstract
The invention discloses a hollow bent flower pipe section and a processing method thereof. The processing method comprises the following steps of: 1, preparing a hollow rectangular pipe section with the structure which is formed by extending the profile (M1) along a linear trace line, wherein the profile (M1) is provided with two vertical straight stripes and two transverse straight stripes; 2, pressing the hollow rectangular pipe section to ensure that the transverse straight stripes are sunken inward to form inward sunken stripes, and an angle of 0 to 60 degrees between the tail end of each vertical straight stripe and the tail end of each inward sunken stripe or the tangent of the tail end of each inward sunken stripe; and 3, pressing the section obtained in the step 2, pressing the linear trace line of the section obtained in the step 2 into a bent trace line to form the hollow bent flower pipe section. The hollow bent flower pipe section has the advantages that: the left and right sides of the section are straight sides, and the angle of 0 to 60 degrees is formed between the tail end of each straight stripe and the tail end of each inward sunken stripe, so angular edges are processed into reinforcing ribs; during bending in the step 3, winkles and breakages are avoided on the bent flower part; therefore, the bent flower pipe section has high strength; and a thin-wall hollow pipe is processed into the bent flower pipe so as to save metal resources.

Step 11 is used for suppressing decorative pattern at the corresponding vertically plate of bar of hollow rectangle pipe profile.
Among one preferred embodiment: also comprise between described step 2 and the step 3:
Step 21 is used for suppressing decorative pattern at the corresponding vertically plate of bar of the section bar of step 2.
Among one preferred embodiment: described step 1 is used for hollow circular pipe profile is pressed into the hollow rectangle pipe profile.
The technical program is compared with background technique, and it has following advantage:
1. two sides are straight flange about section bar, and, vertical bar is terminal to press from both sides into the angle that presss from both sides into the 0-60 degree with indent bar end, makes the described arm of angle be processed into stiffening rib, then in the Forging Process of step 3, curved flower place can not frill, can not break, can reach curved colored best effects, then curved floral tube section bar intensity is high, then thin-wall hollow pipe can be processed curved floral tube, can save metals resources;
2. the indent bar is center of circle arc strip outside, and the indent bar is opening angle bar outwardly, and is easy to process, increases attractive in appearance and intensity;
3. the corresponding vertically plate of bar at the hollow rectangle pipe profile suppresses decorative pattern, perhaps, suppresses decorative pattern at the corresponding vertically plate of bar of the section bar of step 2, increases curved floral tube intensity and attractive in appearance.
4. first hollow circular pipe profile is pressed into the hollow rectangle pipe profile, again the hollow rectangle pipe profile is pressed into curved floral tube, then can gain in strength, can reduce the reject rate that causes because of processing.
