The invention discloses an engine intake manifold machining method. The method includes the steps of S1, machining all parts of an intake manifold; S2, splicing the parts to form an intake manifold blank; and S3, machining a flange face and installing holes of the intake manifold blank, wherein the parts of the intake manifold include the first air outlet flange, the second air outlet flange, theintake flange, a first cylinder branch pipe lower half shell body, a second cylinder branch pipe lower half shell body, a third cylinder branch pipe lower half shell body, a fourth cylinder branch pipe lower half shell body, a first cylinder branch pipe upper half shell body, a second cylinder branch pipe upper half shell body, a third cylinder branch pipe upper half shell body, a fourth cylinderbranch pipe upper half shell body, a resonant cavity lower half shell body and a resonant cavity upper half shell body. According to the engine intake manifold machining method, by dividing the intakemanifold into multiple pieces and splicing the pieces after machining to form an assembly piece, the wall thicknesses of all the parts are easy to control, and the light weight of the intake manifoldcan 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 aluminum alloy intake manifold rapid prototype forming methods include investment casting, wood mold casting and other processes, but these forming methods have a significant 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 areas 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 considering it...
