Abstract
The invention discloses a new energy automobile motor shell heat treatment process which comprises the following steps that a motor shell is flatly placed on a special material frame, and the material frame is hoisted to a feeding rail of a heat treatment solid solution furnace; after the heat treatment solid solution furnace reaches 530 + / -5 DEG C, the material frame automatically enters the heat treatment solid solution furnace, and heat preservation is conducted for 3 hours; after the heat preservation time of the heat treatment solid solution furnace is over, the material frame is automatically transferred into a cooling platform; after the cooling platform senses that the material frame enters, the cooling platform automatically sinks, a product is completely immersed in water, and the temperature of the product is reduced to 100 DEG C or below within 300 seconds; after air cooling is finished, the material frame automatically enters an aging furnace, the temperature is 150 DEG C to 250 DEG C, and heat preservation is conducted for 2 hours; and after heat preservation of the aging furnace is finished, the material frame automatically enters a product discharging area through the rail, after the product is naturally cooled to the room temperature, the product is loaded and taken, and the heat treatment process is finished. According to the new energy automobile motor shell heat treatment process, harsh mechanical property requirements and product overall deformation requirements are met; and the special heat treatment material frame is adopted, so that the productivity is greatly improved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a heat treatment process for a motor casing of a new energy vehicle. Background technique [0002] Because the motor is a core safety component of new energy vehicles, the motor casing needs to bear the weight of the entire motor and even collisions and other factors, and its mechanical properties such as tensile strength, yield and elongation are higher than conventional castings. [0003] The existing heat treatment is a process of solid solution treatment and artificial aging. The motor casing is directly put into a heat treatment solid solution furnace for heat treatment. The shape of the motor casing after heat treatment is prone to warping, which affects the work efficiency. Contents of the invention [0004] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhaustive overview of the invention...
