Description
Technical field
The present invention relates to automobile skin welder fields more particularly to a kind of thin plate arc-shaped workpiece to overlap continuous welding device
And its operating method.
Background technique
Metal plate is be unable to do without as all kinds of light-duty, the heavy-duty machinery manufacturing enterprises based on being machined, container industry
Every production activity, wherein maximum with the yield of sheet member processing and quantity.With automobile (light-duty, passenger car, car it is overcoating
Cover piece) production for, the quantity of thin plate (2.0mm or less) used accounts for 85% or more of total vehicle body, thus solve thin plate processing
Technique, production method become the major subjects of automobile production, manufacture.
The structure of bus roof outer assembly is the top covering of outside covering one formable layer of welding of roof frame assembly, material
For ST12 cold-rolled steel sheet, with a thickness of 1.0mm, surface slightly applies antirust oil.Because width reaches 3.5 meters after the covering expansion of top, length
6-13 meters, since individual roll bending width is not achieved 3.5 meters, realization can be spliced in width direction.Therefore current most visitor
Vehicle manufacturing enterprise uses width to overlap soldering for 1.5 meters of steel plates below and forms, general using 3 pieces of (the pressure left top sides of arc with muscle
Covering, covering in the top with muscle press right top side covering of the arc with muscle), there are 2 longitudinal seams, length and covering length phase in centre
Together.
The implementation of this overlap joint welding structure has 4 kinds: 1. to use the semi-automatic CO2 gas shielded arc welding of manual operations (following
Abbreviation gas shield welding) welding gun, weld seam is fully welded；2. carrying out spot welding using large-sized gantry covering spot-welding equipment；3. using seam weld
Equipment carries out seam weld；4. welding robot welds.
Above-mentioned 4 kinds of welding procedures have disadvantage:
1. advantage is less investment using gas shield welding technique hand-manipulated, construction is flexible, to the position precision and compactness of top covering
Almost without requiring, as long as increasing personnel, can improve efficiency, and can side construction frontier inspection look into, since thin plate is in pressure arc, roller side
In forming process, edge has played wave transformation, when overlap welding, must compress be compacted this 2 layers of coverings after could weld, and it is artificial
Weldering can easily solve this problem.The disadvantage is that welding quality is inconsistent, seam more demanding to the technical ability, physical strength, energy of welder
Weldering height, stomata, slag inclusion, burn-through phenomenon happen occasionally, and such as check and do not come out and repairing in time, and roof will leak water inlet, length
Time welding operation, in addition operating environment is poor, the workload of worker becomes larger, and will generate fatigue, welding quality decline；Welder is
Special work post is influenced by human resources and operating environment, and later welder is fewer and fewer, it is desirable that wage it is higher and higher, use
Work cost is also high；Production technology intelligence degree is low；
2. carrying out spot welding using large-sized gantry covering spot-welding equipment, spot-welding technology, which refers to, is assembled into lap joint for workpiece, and presses
Tightly between electrodes, using low-voltage, high current, short time, resistance heat consumable electrode pressurized portion base metals are formed molten
A kind of welding procedure of core solder joint, large-scale covering spot-welding equipment refers to, and mash welder is arranged on gantry frame, and gantry frame exists
It walks on the track of ground setting, the spot welding of mash welder spot welding head and the time, walking spacing (40mm) and the speed spot welding head that lift
The distance between by 1 console control, advantage is to be able to achieve automation, and solder joint is uniform, welding process without human weld behaviour
Make.The disadvantage is that equipment investment is big (about more than 130 ten thousand yuan of total price)；Point quality cannot be found in time, as spot welding head burns flat, change
Shape or electric current are unstable, are easy to generate pad not blow or burn-through, such as check that repairing, roof will not made out and in time
It is layered and disengages at overlap welding, one amount of the protective layer failure of outside, will leak water inlet；Since spot welding spacing is 40mm, centre is not
The neutral gear of weldering must using can conductive spot welding glue make up, if spot welding glue is too thick, influence electric conductivity, it is not firm to will cause spot welding, such as
Spot welding glue is too thin, influences leakproofness, this requirement is more demanding to operator's construction quality, meanwhile, increase spot welding glue per car vehicle sheet
(10 meters about 180 yuan of vehicle or so)；Although the spacing of spot welding head is controlled by control system, there is no seam tracking system, when in top
When the storage position deviation 5mm or more of covering, spot welding head can deviate from weld seam, and the side weld spacing weld seam of covering is remote in top,
Outside tilts, and influences appearance and sealing, the other side of covering is that solder joint pressure is welded in welded joints or only on the covering of top side in top, is made
Cheng Dingzhong covering solder skip.
3. carrying out seam weld using seam-welding equipment: seam weld is the cylindrical electrode that spot welding is replaced with a pair of of rolling disk electrode, with work
Part performs relative motion, to generate the welding method of the seal-weld of the mutual lapping of nugget one by one.Weldment be assembled into overlap joint or
Banjo fixing butt jointing is placed between two circular electrodes, and idler wheel pressurization weldment simultaneously rotates, and continuously or intermittently power transmission, forms a sequential welding
The electric resistance welding method of seam.Advantage is to be able to achieve continuous welding and automatic welding, must the disadvantage is that seam weld generates biggish heat
It must be using cooling water to cooling of electrode, otherwise easily by electrode melting.Because cooling system be it is open, be unable to closed loop collect circulation make
With a large amount of cooling water flows on weld seam and steel plate, and steel plate is caused to get rusty, and the cooling water for flowing to working site is more, will cause
Operation field is dirtier；Electricity consumption is larger, and energy consumption is higher；Welding quality is similar with spot welding, cannot be found in time, such as welding wheel electrode
It burns flat, deformation or electric current is unstable, it is extremely easy to generate pad not blow or burn-through, it such as checks and does not come out and repairing in time, vehicle
Top will result in overlap welding layering and disengage.This technique has faded away at present, is substituted by other techniques.
4. welding robot welds, advantage is accurate positioning, and welding quality is good, can all positon, automatic welding；The disadvantage is that
Disposably put into larger, influenced by car length, required track is longer, and the precision of track need it is higher, overall cost compared with
(need up to ten million investments) greatly.The technique combination laser welding, gas shield welding connect in Light-duty Vehicle, passenger car and related thick steel sheet
Or using more on component, small-sized plate, but do not answered in passenger-car roof-skin on longer, arc plate using few
Precedent.
