1.Summarize:
The engine crossbeam actually is a kind of variable section H beam steel, with the automobile crossbeam is a very alike product, its assembling and welding craft process more complicated, The equipments mainly is use to solve to variable section H beam steel to assemble and welding, Especially solving to consecution welding at
the transition of variable section and turning transition , Reduced consumedly the handicraft repair-welding in the common craft .This machine is our company for satisfying the market of need, according to the actual experience that many years H beam steel welding to produce, and on the comprehensive reference foundation of domestic and international great deal of similar product, by oneself researched and manufactured ,which is set the pace in craft brother.
2.Equipments purpose:
That machine is provided with variable section H beam steel horizontal assembling and welding, its ability weld two welding seam in same work once, the volume-produce is applicable to same specification variable section H beam steel, the same also is applicable to horizontal assembling and welding the H beam steel, is an essential to have is the efficiently equipments in the steel structure manufacturing industry. At produce the batch quantity bigger should separate into two work place as the horizontal assembling and welding , also can aggrandize the H type steel moving machine or the H type steel 180 traverse type overturn machine etc. equipments.

4. Equipments structure
That equipments welding part mainly make up of: trolley body, column, crossbeam, welding arm , towline framework, flux auto recovering and feeding system, air pressure system, electric box part and Lincoln welding system etc.
The trolley body mainly sustain each part and drive them to travel, it is traveled in the steel rail by its lower part contain two pedestal wheel gear deceleration motor, another have two wheel abut on the steel rail .Its travel speed adopted SPWM AC frequency conversion control way, which is widespread adoption in automation realm currently. Its function stability credibility, the usage convenience, its speed as 0.15-2.5 m/ min, can carry on regulate according to the request of the welding within the allow range.
The crossbeam is fixed in column, mainly sustain two sets of welding drag board, on it installing two beeline guide rail and horizontal rack; The turning electric box is fixed on the column.
The seam tracker of this machine adopted the very dependable wheel lean against machine and the electric controls to combine together, that framework fixed on the crossbeam , it can guarantee the welding gun to aim at welding line and retain the certain clearance always, carrying out the whole variable section beam welding. The welding arm fixed on drag board can be drived by air cylinder, which is drived by welding arm travel motor through magnetism control switch, travel on the crossbeam and make the taper wheel of the welding gun abut against the flange steel of variable section H beam , and have the certain flexibility orientation to variable section H beam ; When variable section flexible scope exceeds the range of magnetism ring air cylinder, the magnetism controls switch to control the travel motor to make the homologous adjustment , another two welding arm top ends has a rise and fall air cylinder respectively, through air cylinder make welding arm act and let the universal wheel under welding gun framework press tightly the beam web steel bypneumatic springiness. .
The flux auto recovering and feeding system make up of fluxcask, which is fixed on drag board and air pressure system . The welding flux is spreaded on the welding seam through valve fixed on welding flux cask , the welding gun follows behind to carry on the welding , recovering tube after welding gun recovers the surplus flux into the tube, then go into flux cask by the sieve net , the whole piece of flux stays in recover cask .
The welding machine adopts American Lincoln full-automatic sub arc welding source , providing with the function credibility, start arc and arc crater stability etc. characteristics, its controls the system is NA-3s, which is belong to the modularization piece, can at any time adjust timing parameter; The machine head adopts the welding method of a kind of high production efficiency as single arc and two wire, having the angle welding seam molding good, the welding feet high etc. advantage ,( once the welding feet height can attain 6-8 mm, if want that the higher , can divide to weld several times)
The electric control system including control box and operation box ,the control box installs to column, can complete all actions of the trolley and adjust welding parameter etc.
The horizontal type variable section crossbeam assembling process equipment mainly including the work table , the web steel fixed position, the flange steel fixed position framework and pneumatic compress tightly equipment, compress tightly air cylinder etc. , 25 meter whole long be divided into much group, the partition of each can according to the request arrange H type steel moving machine or the H type steel 180 traverse type overturn machineetc., according to the general craft need, the welding district not be establish in assembling place, but in another the work place establish a work table or bracket of workpiece .
