Abstract

The invention provides a kind of restorative procedure of numerical controlled gantry type tuber roller bearing fracture, comprise the following steps:1)The roller bearing of fracture is disassembled from tubulation unit, it is clean using grinder buffing, eliminate the tear crackle of section;2)250 350 degrees Celsius are heated to main body section with oxy-acetylene;3)Welding:Using welding rod convex surface, protrusion height 15mm, then again with grinder buffing coning groove, then combine metal filled method with welding rod and connect the small paragraph header of bearing are welded into bearing main body heap;4)Post-weld annealed:Postwelding is heated to 650 degrees Celsius to weld with heater immediately, is incubated 3 5h, is subsequently cooled to room temperature;5)Polishing welding position, reconditioning bead contour, is allowed to seamlessly transit with mother metal.The present invention has the following technical effect that:Roller bearing after repaired can recover normal use, can substantially achieve or close to original level.Work well, normal operation, greatly save time and cost.

Description

The restorative procedure of numerical controlled gantry type tuber roller bearing fracture
Technical field
The present invention relates to the restorative procedure of numerical controlled gantry type tuber roller bearing fracture, belong to field of mechanical technique.
Background technology
Tuber is also known as welded tube mill, tubulation unit, welded pipe units.Through uncoiling, it is molded, welds, polishing, sizing, is straightened, it is fixed The technique productions such as chi, cut-out are formed.Because stainless steel welded pipe is molded, the maturation of welding technique, nothing is substituted in many fields Slit-tube.Such as Anti-theft door and window, balustrade, drinking-water pipe, food hygiene pipe, automobile exhaust pipe, muffler tail pipe, Tube Sheet of Heat Exchanger, Petrochemical pipe, Shipbuilding pipe etc..
Tubulation unit in process of production, is constantly in continuous high speed operating condition, in steel belt molding, roller bearing by To very big extruding force and frictional force, condition of work is severe, and roller bearing is easily broken off, and influences pipe crimping processing.
The content of the invention
The purpose of the present invention is to overcome the weak point of technology, there is provided a kind of numerical controlled gantry type tuber roller bearing fracture Restorative procedure.
The restorative procedure of the numerical controlled gantry type tuber roller bearing fracture of the present invention, comprises the following steps:
1)The roller bearing of fracture is disassembled from tubulation unit, it is clean using grinder buffing, eliminate tearing for section Split crackle;
2)250-350 degrees Celsius is heated to main body section with oxy-acetylene;
3)Welding:Convex surface is welded into bearing main body heap using welding rod, protrusion height 15mm, then uses grinder buffing Cheng Yuan again Taper groove, then metal filled method is combined by the small paragraph header connection of bearing with welding rod;
4)Post-weld annealed:Postwelding is heated to 650 degrees Celsius to weld with heater immediately, is incubated 3-5h, then cools down To room temperature;
5)Polishing welding position, reconditioning bead contour, is allowed to seamlessly transit with mother metal;
Described step 3)Middle welding rod after 350-400 degrees Celsius is baked and banked up with earth 1-1.5h, is stored in baking oven using preceding, It is on-demand.
The present invention has the following technical effect that:Roller bearing after repaired can recover normal use, can substantially achieve Or close to original level.Work well, normal operation, greatly save time and cost.
Embodiment
Embodiment 1
The restorative procedure of the numerical controlled gantry type tuber roller bearing fracture of the present invention, comprises the following steps:
