Therefore be badly in need of research and development one and effectively control welding deformation, ensure derrick column laminating flange and the applying method thereof of the laminating rate between flanged plate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of effective control welding deformation, ensure laminating rate between flanged plate, reduce costs and improve the derrick column laminating flange and applying method thereof that manufacture efficiency.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of derrick column special flange, described Flange joint is between upper pillar stand and lower pillar stand, its innovative point is: comprise and the upper flange plate of upper pillar stand bottom welding and the lower flange plate with lower pillar stand welded top, this upper flange plate and lower flange backboard paste the back of the body and are fitted and connected, and the flanged surface of upper flange plate and lower flange plate is bolted to connection; Described upper flange plate and lower flange plate are fitted and are stitched surrounding and be welded and fixed by horse plate.
Further, the double-edged flatness of described upper flange plate and lower flange plate is (± 0.25mm.
Realize an applying method of fitting between above-mentioned derrick column special flange, its innovative point is: described method is the tow sides first adopting boring drilling and milling machine to process upper flange plate and lower flange plate, ensures that surface smoothness reaches drawing requirement; Then lower flange plate and lower pillar stand are welded and fixed; Subsequently upper flange plate and lower flange backboard are pasted and lean against tight, adopt bolt that the flanged surface of the flanged surface of upper flange plate and lower flange plate is fixed, then fix in the surrounding horse plate spot welding of stitching of fitting of upper flange plate and lower flange plate; Finally upper pillar stand and upper flange plate are welded and fixed.
Further, the surrounding horse plate spot welding of stitching of fitting of described upper flange plate and lower flange plate is fixed, during welding, adopt the welding procedure of symmetrical welding, by two people welding simultaneously from both sides, during welding, freeze horse plate and upper and lower flanged plate is fitted the weld seam that four phases of stitching pass through, welding 3-4 road, then back gouging, polishing mother metal surface 2-3mm, take out carburized case.
The invention has the advantages that:
Derrick column special flange of the present invention, comprise and the upper flange plate of upper pillar stand bottom welding and the lower flange plate with lower pillar stand welded top, flanged surface flatness is high, improves the laminating rate of flanged surface part;
Applying method between derrick column special flange flange of the present invention, relatively at present by the flatness of strict welding procedure control flange laminating, the present invention is by carrying out machining to the tow sides of upper flange plate and lower flange plate, ensure the flatness of flange faying surface, relatively low to the requirement of the operant level of workman, cost-saving, improve the laminating efficiency between flange;
The present invention is when upper flange plate and lower flange plate are fitted, first by bolt and surrounding horse plate, two flanges are rigidly fixed, retrained by the neutral position of bolt, the outside constraint of surrounding horse plate, coordinate again and be symmetrically welded, effectively can control welding deformation, ensure the laminating rate between flanged plate, improve welding efficiency.
