Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of H-shaped steel production process, in particular to an H-shaped steel production process and production line. BACKGROUND

[0002] When the H-shaped steel is produced, the steel plate is first clamped by an electromagnetic suction manipulator to a numerical control assembly machine, so that the web plate and the wing plate are accurately positioned, the H-shaped steel is spot welded by an automatic spot welding mechanism, then the H-shaped steel is conveyed to an automatic welding mechanism by a transmission guide mechanism, and automatic submerged arc welding of the H-shaped steel is realized. The H-shaped steel production line takes automation and integration as the core, and realizes efficient production through multi-process cooperation.

[0003] At present, when the H-shaped steel is automatically submerged arc welded by the automatic welding mechanism, the welding area is covered with granular flux during submerged arc welding, the flux melts and forms slag during the welding process, which protects the weld metal from air invasion. However, after the flux melts, long strip-shaped welding sand bars are easily formed on the surface of the weld, and the welding sand bars contain un-melted flux or impurities. The worker uses an iron rod to remove the excess welding sand bars, but since there are welding sand bars on both sides of the H-shaped steel, the worker needs to remove them on both sides of the H-shaped steel, which not only consumes a lot of time and manpower, but also requires manual removal of the welding sand bars to ensure the consistency and uniformity of the removal effect, thereby ensuring the quality of the weld.

[0088] S1: welding into a T-shaped steel, after splicing one web plate and one flange plate, automatic submerged arc welding is performed by the first group of welding and correcting all-in-one machine 1, and after welding is completed, the welding sand strip on both sides of the welded T-shaped steel is sequentially cut off and scraped off by the two cutting and scraping plates 8, and the scraped welding sand strip is pushed into the inside of the sand suction shell assembly 7;

[0089] S2: point welding, after splicing the welded T-shaped steel with another flange plate, automatic spot welding is performed at the spot welding machine 2;

[0090] S3: turning over, after the point welding, the preliminarily formed H-shaped steel is turned over by the turning machine 3 and moved by the traction mechanism;
