You can find the output part from the H Beam Assembly Machine in the first photo: Fit up and spot welded H Beam. It is a kind of classical H Beam Production Equipment. (Fig.1)
1) For working of I Beam Assembly Machine, “high precision” is the foremost request on its performance:
(Fig.2)
2) The reason is, the essential task of this H Beam Production Equipment is to assemble the flanges and web into H structure and strengthen it with tack welding;
3) So, accurate fitting up in this H Beam Assembling Machine is the foundation for next step of H Beam submerged arc welding and H Beam straightening, for the purpose of delivering qualified finish product of welding H Beam. Improper assembling makes H Beam an unqualified product.
To make accurate assembly and spot welding in the Z15~Z20 High Precision H Beam Assembling Machine, the exquisite design on mechanisms of this H Beam Production Equipment in every step of working is essential for success:
a) As introduced in product section of “Z20 Self Alignment H Beam Assembly Machine with Manual Tack Welding”, during in feeding of raw materials (Flange and web), this hydraulic drive unit pushes the raw materials into its proper position and clip them tightly: (Fig.3)
b) Two sets of the pulling rod system at both ends of input conveyor of the H Beam Assembly Machine makes the web and flange secured firmly and coming into shape of “T” or “H”, in the principle of “Two points make one line”;
c) The pulling rod system is acted with hydraulic cylinder and controlled with button, not manual job;
a) This is core unit for final assembly in the High Precision H Beam Assembly and Tack Welding Machine:
(Fig.4)
b) In one set of H Beam Assembly Machine, there are eight pieces of rollers for web self alignment at its top, and four pieces of rollers for flange self alignment at its bottom;
c) The actions of these alignment rollers are controlled with PLC of the H Beam Assembly Machine without human intervention, making pinpoint assembly of web and flange;
a) To be capable of further managing on precise assembly to its extreme best degree, in this H Beam Production Equipment of High Precision H Beam Assembly Machine, all the alignment rollers for web and flange alignment are all eccentric type (The above mentioned eight plus four pieces, the rollers marked in red color square are for web alignment of the I Beam Assembly Machine, and marked in yellow color are for flange alignment): (Fig.5)
b) As can be observed from the above photo, there is a through slot in the surface of each piece of alignment roller;
c) With a proper tool (such as bolt driver), the alignment roller can have another 2mm adjustable horizontal stroke to acquire the best precise degree of final assembly. This design makes the equipment a truly High Precision I Beam Assembly Machine;
Another measure taken to guarantee exact assembly in this H Beam Production Equipment is web and flange terminal alignment unit: (Fig.6)
a) Imagine the web and flange are sent into the I Beam Assembly Machine and laid on its conveyor for assembling. And suppose terminals of web and flange are not aligned … It is an easy happen issue, because web and flange are two pieces of individual parts;
b) A terminal alignment unit is used here for solving this issue in the H Beam Assembling Machine. At the time web and flange are sent to its proper place in the H Beam Assembly Machine, a cylinder drive fender will erect (Marked in yellow square in above picture), stopping terminals of web and flange, and making them in alignment. This mechanism makes another contribution to the High Precision H Beam Assembly Machine;
c) This unit is operated with corresponding toggle switch on operating pendant of the H Beam Production Equipment. (Fig.7)
