The invention discloses a method for processing an engine intake manifold, comprising the steps of: S1, processing each component of the intake manifold; S2, assembling the components to form an intake manifold body; S3, processing The flange surface and mounting holes of the air manifold body; among them, the components of the intake manifold include the first air outlet flange, the second air outlet flange, the intake flange, the lower half shell of the first cylinder branch pipe, the second cylinder The lower half shell of the branch pipe, the lower half shell of the three-cylinder branch pipe, the lower half shell of the four-cylinder branch pipe, the upper half shell of the first cylinder branch pipe, the upper half shell of the second cylinder branch pipe, the upper half shell of the three-cylinder branch pipe, the upper half shell of the four-cylinder branch pipe The half shell, the lower half shell of the resonant cavity and the upper half shell of the resonant cavity. In the engine intake manifold processing method of the present invention, the intake manifold is divided into multiple pieces for processing and then assembled to form an assembly, the wall thickness of each component is easy to control, and the weight reduction of the intake manifold can be realized .
Description
technical field [0001] The invention belongs to the technical field of engine production technology, in particular, the invention relates to a processing method of an engine intake manifold. Background technique [0002] In the development of the existing piston engine assembly, the rapid prototype molding methods of the aluminum alloy intake manifold include investment casting, wood mold casting and other processes, but these molding methods have a great impact on the wall thickness of the intake manifold during the casting process. There are certain requirements, generally at least 4mm, this wall thickness can avoid the scrapping of parts due to casting defects. [0003] Due to the new application fields of piston engines, there are new requirements for piston engine assemblies - weight targets. In order to meet the weight target requirements of the engine in the new application field, each part of the engine needs to be reduced in weight under the premise of its function...
