Embodiment Construction
[0017] A forging process of an engine casing according to an embodiment of the present invention includes the following steps: S10: putting aluminum alloy raw materials into a melting furnace for melting; S20: ingot-casting the melted aluminum alloy raw materials to form an ingot; S30: Heating the above ingot to 1200°C-1570°C, chamfering, and keeping it warm for 2 hours to 4 hours, and heating the forging mold to 1000°C-1200°C for more than 3 hours, in step S30, the ingot The holding time of the billet is 3 hours; S40: put the cylindrical billet into the forging mold, punch the billet with a punch, make the billet fill the whole mold to form a cuboid blank, and the forging temperature for forging is 1200°C ~1570°C, the final forging temperature is greater than or equal to 1000°C, the opening forging temperature of forging is 1300°C, and the final forging temperature is 1100°C. S50: pre-press and final-press the blank to form a shell; S60: post-forging treatment: first heat to ...

The invention discloses a forging process of an engine shell. The forging process comprises the following steps that 10, an aluminum alloy raw material is put into a melting furnace to be melted; 20,ingot casting is conducted on the molten aluminum alloy raw material, and an ingot blank is formed; 30, the ingot blank is heated to 1200-1570 DEG C, chamfering and heat insulating are conducted, a forged mold is heated to 1000-1200 DEG C, and the heating time is more than 3 hours; 40, the cylindrical ingot blank is put into the forged mold, a punch is used to punch the ingot blank, the whole moldis filled with blank materials, and a cuboid blank is formed; 50, pre-pressing and final pressing are conducted on the blank, and a shell is formed; and 60, firstly, heating is conducted to 800-1000DEG C, and preheating is conducted for 2 hours, then heating is conducted to 1300 DEG C, heat insulating is conducted for 2 hours, the shell is put into oil and cooled to 50-70 DEG C, oil-out and aircooling are conducted, and then low-temperature tempering treatment of 120 DEG C is conducted quickly. The engine shell obtained through the forging process is low in weight and fast in heat dissipation, improves vehicle performance, and lowers fuel consumption.
Description
technical field [0001] The invention relates to the field of vehicle equipment manufacturing, in particular to a forging process of an engine casing. Background technique [0002] With the development of the automobile industry, higher requirements are put forward for the safety and performance of vehicles. In the prior art, the metal materials used for the casing of the engine are mostly iron castings, which are heavy in weight and poor in heat dissipation, which affect the performance of the engine and increase the fuel consumption of the vehicle. [0003] Therefore, how to reduce the weight of the engine casing to improve vehicle performance, and how to improve heat dissipation and reduce fuel consumption have become important technical issues to be solved by those skilled in the art. Contents of the invention [0004] Aiming at the above-mentioned problems in the prior art, the present invention provides a forging process of an engine casing. The engine casing obtaine...
