Description
Technical field
The utility model relates to the inside and outside general welder of courage end face of a kind of automobile tail pipe.
Background technology
Automobile stainless steel tail pipe is widely used in the automobile fitting industry, and description is various.Difference because of automobile discharge capacity and power; requirement to blast pipe also has nothing in common with each other; usually when the bigger automobile of discharge capacity during at application stainless steel tail pipe; because of the temperature of motor exhaust higher; even so at tail pipe surface decorative chromium plating; also might be because of the higher temperature of long period; cause the variable color of chrome-plated surface chromium layer; consider this factor; in the design of tail pipe, the stainless steel tail pipe can be designed to the interlayer of a band sealing usually, to avoid the tail pipe outer surface overheated; cause the variable color of chromium layer, we are referred to as the tail pipe of bilayer zone closed sandwich to this tail pipe usually.
The tail pipe of bilayer zone interlayer is in manufacturing process, and the end face that will carry out between the double-deck inside and outside courage the exhaust outlet position welds.Because of the development of automobile personalization, the tail pipe of the end face of this strap clamp layer weldering has formed a complete series:
Its inner cavity size can change between 53mm-76mm;
Its length dimension can change at 105mm-241mm;
Its angle can be spent between 75 degree 56 and change;
The stainless steel end face is welded in the argon arc welding procedure, belongs to the bigger welding procedure of difficulty.It is different from common edge weld, and its inside and outside courage wall thickness changes at 1.2-1.5mm usually in addition, belongs to the thin-wall part welding.Because of the outlet of cylinder staving workpiece is a bigger oblique angle, when welding, the workpiece face of weld is the ellipse of a rule, and this gives to weld has automatically increased difficulty.Therefore in the mill, at present general is manual welding.When problem was manual welding, when other process conditions all met welding conditions, operative employee's hand when operation will be made X along the solder side of workpiece, Y, Z, axial three-dimensional motion, to welder's skilled operation and operative skill require high.
When weld job, the three-dimensional motion of hand can not form a Wan Mei De rotation at the weld job face and turn-take.Solder side divides secondary to finish usually during concrete the welding, finishes the curve of a semiellipse type at workpiece end face at every turn, after two curves overlapped, forms a complete disciform weld seam.Article two, weld seam overlapping, because of the overlapping of arc received in the starting the arc, difficulty increases and causes the welding difficulty of this series products high on handling.
In the follow-up electroplating work procedure of workpiece sanding and polishing, problem has just displayed.The higher gradient along with outlet of the ratio of leaking after this series products is electroplated increases the ratio of leaking and increases, and leakage area concentrates on the overlapping of weld seam, and ratio is up to 85%.
Because of the inner chamber of sealing when welding is finished, formed the negative pressure attitude in the closed inner chamber, when electroplating, in case weld seam has minute defects, in electroplating process, plating bath will be penetrated in the closed sandwich of workpiece, the water inlet of electroplate seepage, thus finally become waste product.
Summary of the invention
