Description
Technical field
The present invention relates to a kind of engine exhaust manifold assembly, be specifically related to a kind of vertical engine exhaust manifold assembly of putting.
Background technique
The effect of engine exhaust manifold assembly is the waste gas that collects each cylinder of motor, avoids the exhaust phase mutual interference between each cylinder as far as possible, makes waste gas safety and discharges as much as possible motor completely.Trend and the structural design of gas exhaust manifold are extremely important, in meeting the power economy performance of motor, simplify the machining process of product as far as possible.At present, in engine exhaust system, stainless exhaust manifold assembly air flue adopts two half-shell air flues mostly, and also some adopts stainless bend pipe to add two halves shell combined type air flue.Two half-shell gas adopt both sides welding, welding procedure complexity, the problem of full robot welding sometimes cannot solve assembly welding time; Stainless bend pipe adds two halves shell combined type air flue, the problem of full robot welding while having solved assembly welding completely.The two halves shell of two kinds of air flue modes all adopts both sides welding, welding procedure complexity, and stock utilization is lower, and therefore cost is higher.
Summary of the invention
The object of this invention is to provide a kind of vertical engine exhaust manifold assembly of putting, in the limited arrangement space of solution, arrange and meet under the prerequisite of engine power economic performance requirement, simplify the welding procedure of exhaust manifold assembly air flue, to reduce costs.
Technological scheme of the present invention is as follows:
A kind of vertical puts engine exhaust manifold assembly, comprise that air inlet flange disks, many bend pipe air flues, one gather air flue, steam outlet pipe, the flange plate of giving vent to anger; One end of bend pipe air flue is connected to and is gathered on air flue by the mode of inserting and welding, and the other end is connected on inlet flange by the mode of inserting and welding equally; Described steam outlet pipe one end with gather air flue and be connected, the other end is connected with the flange of giving vent to anger.Its improvement is: described in to gather air flue be stainless steel materials impact briquetting, there is a He Yugai base, plane base and bend mutually the first circular arc side and the second circular arc side of connection, described two circular arc sides are crowded around and are adopted monolateral being welded to connect.
Further improve, described in gather air flue cross section for semicircle, described the first circular arc side and the second circular arc side are arranged symmetrically with along weld seam.
Stainless exhaust manifold assembly air flue of the present invention adopts stainless bend pipe air flue and gathers air flue combination, adds the comparison of two halves shell combined type air flue with two half-shell air flues or stainless bend pipe, has following advantage:
1, gathering air flue is monolateral welding, and stock utilization is higher, has saved cost;
2, simplify welding procedure, can realize full robot welding, enhance productivity;
3,, in limited arrangement space, can better arrange the air flue that meets the requirement of engine power economic performance;
4, improved the reliability of product itself.
