When using the utility model, to require the steel pipe in cross section (garden, side, rectangle etc.) to be stuck on the no mould stretching-machine by fixed chuck 4 and stretching dop 6, under the effect of tensile force, by local fast heating and cooling and accurate control Cooling and Heat Source translational speed V fast
2With draw speed V
1Cooperation, do not use mould and vertical change section configuration of making steel pipe obtain expecting, finish tissue and mechanical performance that thermomechanical treatment improves steel pipe simultaneously.Arbitrarily the section shrinkage rate in cross section only with Cooling and Heat Source translational speed V
2With draw speed V
1Relevant, its value is:
R=(V
1/ V
2)/(1+V
1/ V
2) or R=V
1/ (V
1+ V

In the formula: R is a section shrinkage rate.
The following formula explanation is by changing the ratio of draw speed and Cooling and Heat Source translational speed, vertical change section configuration that can obtain to require.The wall thickness in vertical each cross section of conical pipe and the external diameter of this section, internal diameter and section shrinkage rate are set up the following formula relation:
t
f/t
o=d
of/d
o=d
tf/d
t=1-R
f
In the formula: t
fThe wall thickness of the f section the after-stretching,
d
OfThe external diameter of the f section the after-stretching,
d
TfThe internal diameter of the f section the after-stretching,
t
oThe wall thickness of-preceding the steel pipe that stretches,
d

R
fThe section shrinkage rate of-f section.
In use, for obtaining to require the vertical section shape accurately, must accurately control V
1/ V
2The Cooling and Heat Source translational speed depends on steel grade and heating efficiency, can not change arbitrarily, therefore must reach control V by the control draw speed
1/ V
2The purpose of ratio, make section shrinkage rate be varied to the longitudinal shape of requirement on request.
For guaranteeing product quality, the no die drawing of accurate control is stretched conical pipe draw speed computer control Mathematical Modeling and is:
V
1/V
2=[1/(1-2xtgφ/d
o)
2]-1=[1/(1-2V
2ttgφ/d

In the formula: d
oThe external diameter of-mother tube or length of side mm;
The t-stretching time, second;
The cone angle of φ-conical pipe, degree;
Because d
o, φ, V
2Be constant, following formula then becomes: V
1=f (t)
Promptly be independent variable control draw speed with time, computer can be controlled automatically like this.
