Background technology
Crane is as the main mechanical of material lifting, transport, handling or installation, in the national economic development of China, obtain extensive utilization, strengthen being of great significance the material lifting of raising China, transport, handling or the horizontal tool of installation the research of crane and improving.Current China is widely used in the crane mainly bridge crane of the industries such as machinery, metallurgy, transport, electric power, coal, building, and the crane span structure of bridge crane is main bearing carrier, and it mainly bears deadweight and hoisting heavy weight.Crane end carriage is located at the both sides of crane girder, for support main beam, the structure of current crane end carriage is substantially all made up of web and cover plate, web is an integral plate normally, and wheel group is installed on web, and the intensity of the end carriage needed when the load-bearing of crane is larger is just large, the specification of the wheel group used also wants large, the thickness of web will increase by the intensity that generally for increases end carriage, and so just cause consumptive material more, manufacturing cost is higher.
Summary of the invention
The object of this invention is to provide a kind of production technology of crane end carriage, make that end carriage is easy to process, bearing strength is high, safe and reliable.
For achieving the above object, the technical solution used in the present invention is:
A production technology for crane end carriage, is characterized in that, comprises the following steps:
(1) pre-treatment of raw material: must not there be corrosion and scar in raw material surface, the defect such as slag inclusion, layer skin must not be there is in inside, and straightening, impeller blasting are carried out to it, the pretreatment such as to prime;
(2) blanking: the upper and lower cover plates needed for end carriage, web, dividing plate etc. are first rule by drawing, re-uses cutting machine cutting stock;
(3) cleaning and correction: remove the things such as slag that cut at the position needing welding, and bevel for welding of polishing, correct welding assembly, make it reach flatness requirements;
(4) spot welding is assembled: upper cover plate, dividing plate, web assembled as requested and fix, the connecting plate spot welding of docking port place, postwelding draws the position, hole on connecting plate, according to position, hole drill reaming;
(5) erection welding: the upper cover plate assembled, dividing plate, web are welded, ensure perpendicularity and the levelness of bent plate, inside is first welded by hand, weld with Lincoln weld again, lower cover is welded again after welding, each postwelding all will remove welding slag, the polishing crator of internal organ, and detects the quality of weld seam, ensures perpendicularity and the levelness of often organizing two pieces bent plate and each parts;
(6) correct and assemble: correcting bent plate perpendicularity, assemble wheels, and detect the two axles depth of parallelism, the perpendicularity of two-wheeled end face and coplane degree;
(7) self-inspection and specially inspection: self-inspection is carried out to the end carriage produced, specially examines after stamping steel seal, then etc. to be assembled.
Further, upper cover plate, when welding, first lies on platform, puts web and partition position line, spot welding large baffle by step (5), welding large baffle; Lift web again on upper cover plate, early stage, tack welding was on upper cover plate, and group is to π type beam according to drawing bevel; Then large baffle weld seam, web and upper cover plate inside fillet is welded, alignment π type beam; Finally lift π type beam tack welding web and lower cover on lower cover, welding end carriage, postwelding corrects alignment end carriage, and spot welding bent plate also welds.
Further; when upper and lower cover plates and web welding; welding wire adopts H08A or H08MnA; solder flux adopts HJ431, gage of wire 4 mm, and slope type adopts I type, V type, Y type, two-sided Y type groove according to steel plate thickness; after first surface has welded; reverse side adopts carbon arc air gouging back chipping and grinding process, decarbonizing and oxide, and wing angle welding adopts the welding of CO2 gas shielded arc welding.
Beneficial effect of the present invention:
The present invention adopts such scheme, technique advantages of simple, easy to process, and welding adopts welding technology of automatic submerged-arc welding, welding deformation is little, and weld strength is high, and residual stress is little, improves the bearing capacity of end carriage, safe and reliable, manufacture and easy to maintenance, reduce entreprise cost.
