Production practices finding, former technique there is problems in that 1. welding processes are higher to the dependence of the technical merit of operative employee；2. operative employee must stare at solder joint closely, for a long time, affects workers ' health；3. welding workpiece sliding speed and solder joint heating degree when welding is difficult to control, it is easy to cause the aluminum base of the rail to melt；4. bigger owing to once welding easy finished work-piece amount of deflection；5. leading screw adjusts pressue device operation excessively complicated, and it is unbalanced that the aluminum base of the rail is coated with power by rustless steel J section bar；6. turnover solder joint gantry design production site area is bigger along its length.
Summary of the invention
It is an object of the invention to overcome the weak point in existing rustless steel J section bar steel-aluminium composite conducting rail manufacturing process, Import computer programme-control, successful experimental data is inputted, use.Thus providing a kind of intelligentized solder technology, reduce the impact of artificial uncertain factor.Reduce manufacturing cost, improve row yielding.Thus, adopt the welding procedure got twice the result with half the effort to produce the rustless steel J section bar steel-aluminium composite conducting rail product of high-quality.
This invention address that it technical problem is that takes techniques below scheme to realize.
A kind of Intelligent welding platform of Novel steel aluminium composite conducting rail, its characterized by techniques:
(1) will be placed on workbench datum level king's font aluminum rail hydraulic locking mechanism fixes.
(2) two rustless steel J section bars are coated on the two sides of aluminum rail upper end, and the curved end of rustless steel J section bar is embedded in the groove of king's font aluminum base of the rail upper side.(such as Fig. 1)
(3) press both horizontally and vertically going up with the other hydraulically operated fixture two rustless steel J section bars to being coated on aluminum rail, it is ensured that rustless steel J section bar is tight, straight with the cladding of aluminum rail simultaneously.
(4) welding machine controlled with movable-type intelligent, the end face abutment joint welding two rustless steel J section bars being coated on aluminum rail welds.
King's font aluminum rail is fixed and is realized by hydraulic locking apparatus, and coupling mechanism force is adjustable.Its composition is fuel tank, oil pump and the hydraulically powered locker of many groups.
It is coated on the held location of rustless steel J section bar on aluminum rail, fixing and holding mechanism is uniformly distributed clamping along its length and realizes.Clamping device forms: computer, sensor, motor etc..Computer program controls, and pressure regulates.(such as Fig. 2)
The movable welding connection device that the rustless steel J section bar being coated on the aluminum base of the rail is welded, is made up of welding machine, dolly, servomotor, change speed gear box etc..Dolly gait of march is by programme-control；Welding current and weld point temperature are by programme-control.
Advantages of the present invention and having the benefit effect that
1. fixing to workpiece aluminum rail of the hydraulic locking apparatus on welding bench, position is accurate, pressure is uniform and easy and simple to handle.
2. the welding method having been proven in practice that is passed through computer utility, it is ensured that the bigger material of two kinds of melting temperature gaps namely: rustless steel and aluminum, produce stress when composite welding small, produce amount of deflection after welding less, and facilitate straightening.
3. the clamping device of rustless steel J section bar before welding, welding in very welding after cooling continue, be greatly reduced become rail deformation.
4. data base has Optimizing Process Parameters, can adjusting process parameter in time.
5. computer passes through the biosensor analysis such as temperature, pressure, is operated by programme-control welding current, weld point temperature and dolly gait of march etc., performs optimised welding procedure.
6. the guide rail carrying welding machine dolly is parallel with workpiece, it is ensured that straight at workpiece weld bond.
7. adopt workpiece to fix, put down into the mode cleared；Welding machine moves welding procedure.Save workshop area, reduce cost of land.
