1.The role of pipe welding machine in the manufacture of automobile frame
Pipe production: The welding pipe machine is used to manufacture high-precision welded steel pipes, which constitute the longitudinal beams, beams, anti-collision beams and other key components of the automobile frame. High frequency welding (HFW) or laser welding technology can produce steel pipes with uniform wall thickness and strength of more than 800MPa to meet the needs of lightweight.
Customized processing: Through flexible forming technology, the welding machine can produce special-shaped cross section pipes (such as rectangular, trapezoidal), adapt to the topology optimization design of different models of frames, improve space utilization and impact energy absorption efficiency.
2.The core requirements of the welding pipe process for automobile frames
Material properties: DP600/DP800 duplex steel or 22MnB5 thermoforming steel should be used, and online heat treatment (such as induction annealing) should be carried out after welding to ensure the microstructure consistency between the weld zone and the base material and avoid HAZ (heat affected zone) softening.
Dimensional accuracy: Diameter tolerance should be controlled within ±0.2mm, ellipticity ≤0.5%, to ensure the matching accuracy of the assembly and stamping parts (clearance <0.5mm).
3.Key technology breakthrough point
Laser-MAG composite welding: the penetration depth can reach 8mm, the welding speed is increased to 6m/min, the heat input is reduced by 30%, and the welding deformation of the frame is significantly reduced (≤1.5mm/m).
Online quality monitoring: high-speed CCD vision system (sampling rate 2000fps) with eddy current detection, to achieve real-time detection of weld defects, miss rate <0.01%.
4.Cost-performance balance
Compared with the stamping and welding structure, the welded pipe frame can reduce the weight by 15-20%, the material utilization rate is increased to 95%, and the manufacturing cost of the bicycle is reduced by about 1200 yuan. However, it is necessary to increase the investment in roller forming molds (about 2 million yuan/set).
5.Industry Application Cases
- An independent brand pure level station adopts 3D variable cross-section welded pipe subframe, with torsional rigidity increased to 27000Nm/°, 40% higher than the traditional structure, and the battery pack space utilization increased by 12%.
Conclusion
The penetration rate of welded pipe technology in the field of automotive frames is growing at a rate of 8% per year, and future development directions include:
Intelligent welded pipe system (digital twin model real-time control molding parameters)
Magnesium alloy /CFRP composite pipe welding process
Topological optimization driven continuous forming technology for variable thickness pipes
It is recommended to pay attention to the update of the ISO 15614 standard and the latest certification requirements for automotive welded pipe processes in ASME BPVC Section IX to ensure technical compliance.
