Description
Technical field
The present invention relates to a kind of longitudinal seam welding of barrel device, be specifically related to a kind of automatic soldering device of truck air tank longitudinal joint.
Technical background
At present, the welding production of cylindrical shell longitudinal joint generally adopts cantilever structure welding machine to carry out.This welding machine is grouped into primarily of support, cantilever beam, back shaft, key plate, centering body, padlock, welding gun walking mechanism, welding gun clamping and welding gun governor motion, electrical control division.Its course of work is mainly divided into four steps: be first carry out tack welding to cylindrical shell to connect, by fixed for the preliminary pad on positioning fixture of the cylindrical shell after volume circle; Two is material loadings, cylindrical shell after point is fixed is placed on the cantilever beam of welding machine, and with key plate, cylindrical shell is clamped, parallel with welding gun walking mechanism for ensureing longitudinal seam, and make welding gun aim at weld seam, use longitudinal joint position, centering body location when cylindrical shell material loading is installed, finally lock cantilever beam with padlock mechanism, improve welding machine rigidity; Three is welding, and the welding gun starting the arc also have been advanced welding by certain speed under the dragging of walking mechanism; Be finally blanking, after welding, open cantilever beam padlock mechanism, cylindrical shell is unloaded from cantilever beam, complete longitudinal seam welding of barrel.
There is the problem of following three aspects in this cantilever design welding machine:
First, easily there is weld defect in weld seam.On the one hand, although adopt centering body to define position while welding when cylindrical shell is installed, but because centering body, welding gun walking mechanism all exist certain interval, be difficult to ensure that welding gun is in Weld pipe mill always, welding bead is caused to depart from, producing weld defect, showing when adopting plasma or laser TAG welds particularly evident; On the other hand, the weld seam both sides welding heat of docking can not be completely the same, distortion is also not the same, simultaneously because piano type clamp system clamping force is limited, insufficient clamping force, to overcome owing to welding thermogenetic workpiece deformation, make butt weld both sides produce the height upper deviation, and this very easily causes weld defect, especially, when the larger material of this kind of linear expansion coefficient of cylindrical shell employing stainless steel, during weld defect, generation is had.
Two is that postwelding barrel distortion is large, and welding machine does not correct the mechanism due to welding heat initiation welding deformation, and postwelding cylindrical shell section deformation is comparatively large, and affect follow-up end cap group to assembling and weld job, product appearance is of low quality simultaneously.
Three is that production efficiency is lower, need carry out tack welding and connect before barrel soldering on positioning fixture, and the assembling of welding conveyor front barrel and postwelding cylindrical shell unload from cantilever beam, all need to expend time in, and material handling, waste time and energy.
(application number is Chinese invention patent application: 201210322324.8, date of publication is: on 03 26th, 2014, name was called: tunnel type cylinder longitudinal seam welding machine) disclose a kind of cylindrical shell longitudinal seam automatic welding connection device integrating charging, centering, welding, discharging.The feeding mechanism of this device is made up of the roller of some groups of symmetrical up and down active rotation, relies on the frictional force drives cylindrical shell between cylindrical shell and charging roller to move forward, successively by feeding mechanism, welding mechanism and discharging mechanism.Although this welder solves the low problem of above-mentioned cantilevered bonding machine production efficiency, but the feeding manner of this welder easily occurs that charging is not smooth in actual use, charging rate is uneven or treat the problem that welding line is larger, there is weldquality instability in the cylindrical shell longitudinal joint that this device welds, (main cause is in following two: one for the problem that qualification rate is low, the plate length being rolled into cylindrical shell is actually impossible on all four, error will inevitably be there is, that is there is error in the diameter of welded cylindrical shell, when diameter is larger, cylindrical shell can be very large by resistance during welding mechanism, easily occur that charging is not smooth, but when diameter is less, easily there is the problem that weld gap to be welded is large, welding quality is made to be difficult to ensure, two, welding process is uneven to workpiece heat, will inevitably produce welding deformation, during the material that especially this kind of linear expansion coefficient of soldering stainless steel is larger, welding deformation is more obvious, the resistance that now cylindrical shell passes through in welding mechanism can unpredictably change, thus it is not smooth to bring out charging yet).The welder of this structure is poor to cylindrical shell plate length fault-tolerant ability, more easily do not produce weld defect by force, still to the charging change in resistance adaptability that welding deformation produces, meanwhile, the structure of this device also comparatively complicated, to manufacture maintenance cost higher.
