Problems solved by technology

However, at present, when the engine case cover is manufactured, the case cover is generally designed to be thin, resulting in insufficient structural strength, especially in terms of materials. When the engine case cover is manufactured, the cooling efficiency is not high enough, resulting in a long process time.

Abstract

The invention discloses a machining process of an automobile four-column engine case cover. The machining process of the automobile four-column engine case cover comprises the following steps of step 1, preparing a raw material, wherein the raw material is aluminum alloy which comprise the following components in percentage by weight: 0.01 to 0.05 percent of Fe, 1.2 to 1.5 percent of Mn, 0.5 to 1.0 percent of Ni, 7.5 to 9.0 percent of Zn, 2 to 2.5 percent of Ti, 1.5 to 3.0 percent of Mg, 1.0 to 2.0 percent of Cu, 0.1 to 0.2 percent of Sc, 0.1 to 0.2 percent of Zr, 0.01 to 0.05 percent of Si, and the balance Al; and mixing the above components in parts by weight to prepare an aluminum ingot. The formula of the aluminum alloy is improved, the aluminum alloy contains Fe, Mn, Ni, Zn, Ti, Mg, Cu, Sc, Zr, Si and Al, a gypsum mold can be added after smelting to manufacture the engine case cover, and the structural strength of the manufactured engine case cover is higher than the structural strength of a traditional material.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to a processing technology for an automobile four-pillar engine case cover. Background technique [0002] The engine is composed of two major mechanisms, the crank connecting rod mechanism and the gas distribution mechanism, and five systems including cooling, lubrication, ignition, fuel supply, and starting system. The main components are cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc. The working cavity of reciprocating piston internal combustion engine is called cylinder, and the inner surface of cylinder is cylindrical. The piston reciprocating in the cylinder is hinged to one end of the connecting rod through the piston pin, and the other end of the connecting rod is connected to the crankshaft. The crankshaft is supported by the bearing on the cylinder block and can rotate in the bearing to form a crank connecting rod m...
