Description

A kind of cast-iron exhaust manifold

Technical field

The utility model belongs to automobile gas exhausting manifold branch technical field, is related to a kind of cast-iron exhaust manifold.

Background technique

Enmgine exhaust currently on the market is due in irregular shape, and structure is complicated, and conventional fabrication processes are with casting The surface treatment method of iron monoblock cast, casting exhaust manifold part generallys use traditional antirust oil anti-corrosive technology, this exhaust For the joint face of manifold intolerant to abrasion, and since exhaust manifold working environment is severe, antirust oil rust-proof life is only six months, exhaust The easy corrosion of manifold outer wall, presentation quality are poor.Simultaneously because exhaust manifold works under high temperature circulation alternating capacity for a long time, it is long Phase is previous, its pipeline can be undergone phase transition, and phase transformation will lead to conduit volume and change, and is allowed to generate interior variable force or change Shape influences the service life of product.

In conclusion needing to design a kind of heat-resisting quantity and corrosion resistance for enhancing manifold exhaust pipe, extend pipeline The cast-iron exhaust manifold of service life.

Summary of the invention

The purpose of this utility model is the presence of the above problem in view of the prior art, propose it is a kind of installation it is firm, enhancing The heat-resisting quantity and corrosion resistance of manifold exhaust pipe, extend the cast-iron exhaust manifold of the service life of pipeline.

The purpose of this utility model can be realized by the following technical scheme: a kind of cast-iron exhaust manifold, including successively set Manifold channels, main pipeline and the oblique branch pipe set and be linked together, are equipped with mounting flange, the manifold channels outside oblique branch pipe It is bent outwardly and is formed and manifold channels are connected with the bending place of both main pipelines by connecting flange, the connection method by main pipeline Blue and main pipeline, manifold channels are wholely set, and heat shield installation lug is equipped in manifold channels, is distinguished in main pipeline two sides It is provided with strengthening rib strip, the strengthening rib strip extends on the outside of manifold channels and oblique branch pipe to both ends respectively, on the outside of main pipeline Around two circular ring shape stiffener plates are equipped with, wherein a stiffener plate is close to oblique branch pipe, another close to manifold channels.

Multiple installations are also separately installed on the outside of main pipeline and manifold channels as a further improvement of the utility model, Support.

Integral type is provided with raised mounting structure on main pipeline as a further improvement of the utility model, is pacifying Mounting base is detachably installed, the mounting base is equipped with fixing threaded hole on assembling structure.

The manifold channels, main pipeline, oblique branch pipe are by alloy cast iron material one as a further improvement of the utility model, It is body formed to be made.

Based on the above-mentioned technical proposal, the utility model embodiment at least can produce following technical effect: this cast iron exhaust Manifold overall construction design is reasonable, compact, and it is firm to install, and strengthening rib strip is respectively set in integral body structure two sides, is being responsible for Stiffener plate is set on road, the stress danger zone that thermal deformation generates can be transferred to strengthening rib strip and reinforcement from manifold body Gusset, and it is evenly dispersed circumferentially do not generate stress concentration point, avoid damage to occur, while optimizing exhaust manifold thermal shield Installation point is arranged on the lower position of temperature by the position of installation point as far as possible, is avoided heat-insulated in areas of higher temperature arrangement Cover installation point effectively prevent damage of the high load capacity to exhaust manifold, and firm firm, durability is higher, extends service life.
