According to the method, personalized technological parameter generation and dynamic closed-loop control are combined, the problems that a traditional leveling method is poor in adaptability to coil steel metal plates in different states, low in leveling precision and prone to secondary stress damage are solved, the leveling efficiency and the finished product quality are remarkably improved, and the rejection rate of follow-up machining of a vehicle frame is reduced.

A pipe fitting structure for easy connection
ActiveCN224397368Uprevent slidingInhibit sheddingSleeve/socket jointsPipe fittingStructural engineering
The utility model discloses a pipe fitting structure convenient to connect relates to pipe fitting connection field, including pipe fitting one, the pipe fitting one end is inserted with pipe fitting two, the pipe fitting one and pipe fitting two between the insertion have connecting piece for the pipe fitting one and pipe fitting two inner wall jacking, the connecting piece is by top rhombic frame, middle straight pole section and bottom cross section three part constitutes. Advantageous effect lies in: connecting piece adopts top rhombic frame, middle straight pole section and bottom cross section's integrated structure. Bottom cross section is X shape structure, utilizes barb principle and pipe fitting one inner wall close contact, forms stable radial support after inserting, effectively prevents connecting piece in pipe fitting one and slide or fall off. Top rhombic frame width is greater than pipe fitting one inner diameter, and after the contact with pipe fitting two inner wall, produces elastic top tight force, realizes pipe fitting two and connecting piece's firm cooperation, has enhanced the integral anti -vibration of pipe fitting one and pipe fitting two after connection obviously, avoided traditional insertion structure's loose problem.
