h beam flange straightening machine,
h beam automatic welding machine
High quality H-beam automatic welding straightening line combined PLC
The H beam automatic welding line consists of slitting and cut to length machine,web forming machine,flange,wed feeding machine,corrugated web H-beam robot automatic welding machine,corss-section cutting,output system and so on. This machine has high quality,high efficiency,full-automation.It centralize the assembly, welding and straightening functions on one machine which saves space and economize workshop.
Welding method: lat SAW (single wire)
Max fillet height: 8mm
Input conveyor: total 12m, three pieces, one of them is driver
Output conveyor: total 12m, two of them are elevated
Working speed: 0.2-2m/min
Total power: 20KW+150KVA
There are three groups of mechanical hands for positioning and centering of flange & web, between the input conveyors. When feed strip into the machine, these hands can help support strip and center, avoid tilting.
Two groups of position device for web & flange. One side is by lead screw, the other side is by hydraulic pressing, which can locate the strip with precision. The position devices are synchronized through shaft on reducer.
After flange and web are feed into the machine body, the end alignment will lift automatically to align the end of web and flange.
Use two sets of American LINCOLN DC-1000 welders to weld two seams at the same time. Each side is single arc welding (wire Ф3.2/Ф4mm). High efficiency and perfect welding quality.
The welding torches can be adjusted freely, and be observed during whole welding.
Two sets of flux feeding & recovery system are installed on this machine. The flux is feed onto the seam before torch, and there is suck mouth after torch, which can recovery un-finished flux automatically for recycle working.
The flange will be deformed because of heat from welding. At the output side of machine, we set a straightening device to correct the deformation.
The thickness can be corrected as following table(σb≈400Mpa):
|Flange thickness B(mm)||6～16||16～25||25～30||30～38|
|Flange width T(mm)||200～1000||450～1000||650～1000||800～1000|
After finish welding, the beam on output end will raise because web is heated at single side, hence, we set two elevated conveyors at output side to support the beam.
It has variable speed, indicated by digit displayer. The whole machine is controlled by PLC.
