Rounding pipe steel member (thin-wall circular tube).
Step 2: three-dimensional authentic model 1 is subjected to setting-out expansion, wherein the starting of evolute 2 is opened on three-dimensional authentic model 1
Mouth, which is arranged at the wave crest for mutually passing through 3 ports of end of three-dimensional authentic model 1, (to be passed through the edge line at end 3 mutually as sine curve, has after expansion
Wave crest and trough)；The plan view 4 of 1:1 after export expansion.
Step 3: the plan view 4 of 1:1 being imported in Sinocam software and works out cutting process, obtains cutting process file,
Include the shape etc. of steel plate after cutting path, cutting in cutting process file, when cutting, control cutting torch according to this route into
Row cutting.
Step 4: placing steel plate 5 to be cut in fully automatic cutting machine bed, according to cutting process file, adjusts to be cut
5 position of steel plate, and carry out accurate blanking along cutting line 6 using fully automatic cutting machine bed, obtain the steel plate 7 that cutting is completed；
Step 5: the steel plate 7 that cutting is completed is placed on roll-forming on veneer reeling machine 8.
Step 6: healing up to the round tube steel member 9 of roll-forming and longitudinal seam welding；When the round tube steel structure of roll-forming
When 9 two sides of part heal up, the gap at the place that heals up is subjected to spot welding, solder joint is arranged one every 1000mm, and every place's fusion length is not
Less than 50mm；The gap at the place that heals up is welded after the completion of spot welding, weld reinforcement is not more than 2mm.
Certainly in other embodiments, the distance of solder joint can be true within the scope of 800m ~ 1200mm according to construction environment

It is common.
2, principle is rolled；When rolling, steel plate is placed between the roll shaft up and down of veneer reeling machine, and when the decline of upper roll shaft, steel plate is just
By moment of flexure effect and occur bending and deformation, due to the rotation of upper and lower roll shaft, the frictional force passed through between roll shaft and steel plate is driven
Steel plate is mobile, and steel plate depressed position is made continuously to change, to form smooth curved surface, completes roll-forming work
Make.
3, steel plate rolls；
It a) is D to internal diameter when symmetrical three rolls plate bending machine rolls1Round tube steel member, roll radius of curvature be D1/2+
It is as shown in Figure 4 to roll rear shape by 300mm.
B) it when the round tube steel member of roll-forming heals up, is pushed at the position Fig. 4, according to proper sequence principle, under each
Height 50mm is pressed, then carries out turning to both ends and heal up, shape is as shown in Figure 5 after healing up；When both ends remained straight edge is healed up, it is necessary to
The defects of guaranteeing to heal up, it is smooth to locate, and joint gap controls between 0 ~ 2mm, does not allow misalignment.
In the present embodiment, longitudinal seam welding is used at the automatic welding center of the round tube steel member 9 of roll-forming in step 6
Or carried out on Special Automatic welding positioner, outside is all made of automatic submerged arc welding and is welded in the round tube steel member 9 of roll-forming
It connects.
Above-mentioned technique, will be theoretical unified with reality, and software is combined with construction, has been saved material from source, has been reduced construction
Process ensure that the efficiency and quality of construction, provide resolving ideas and method for subsequent more complicated component production.
