Abstract
The invention relates to a heat treatment method of a mounting frame of an air conditioner motor. The mounting frame made of 65Mn material is processed through vacuum heat treatment, and is washed by gasoline; the mounting frame is processed through drying and heat preservation under certain temperature for certain time; the preheating is performed in a vacuum firing furnace, and certain heating rate, holding temperature and time are controlled; certain heating rate, holding temperature and time are controlled in the vacuum firing furnace, high purity nitrogen is charged until the pressure is 0.056MPa, then the mounting frame is put in quenching oil so as to stir for 12 minutes; antirust water is used for washing and cooling; temper is performed in a tempering stove, certain holding temperature and time are controlled, oil dripping is performed for 3 to 5 minutes, and the air cooling is performed until the room temperature is reached; the mounting frame is washed by the gasoline after the temper. The heat treatment method obtains the rigidity that reaches HRC37-48 which accords with the American ASTM4169 truck vibration standard 2-grade, the service life is long, and the unsafe hidden dangers are eliminated.
Description
Technical field:
The present invention relates to air conditioner motor, particularly relate to a kind of heat treating method of mounting frame for air conditioner motor.
Technical background: existing mounting frame for air conditioner motor material adopts the method for 65Mn Conventional Heat Treatment, and hardness reaches HRC22-26, and with 2 grades of tests of U.S. ASTM4169 truck vibrations standard, support ruptured after 2 hours, and work-ing life is short, has hidden danger.
Summary of the invention:
Purpose of the present invention is exactly the heat treating method that a kind of mounting frame for air conditioner motor will be provided, and it can overcome the existing defective of method that existing mounting frame for air conditioner motor material adopts the 65Mn Conventional Heat Treatment well.The object of the present invention is achieved like this, and a kind of heat treating method of mounting frame for air conditioner motor is to adopt the mounting bracket of 65Mn material to carry out vacuum heat treatment, and its vacuum oven process of thermal treatment is as follows: mounting bracket is cleaned with gasoline; Drying treatment, holding temperature are controlled at 105 ± 5 ℃, and soaking time is controlled at 12 ± 3min; Preheating in vacuum oven, rate of heating are controlled at 60-70 ℃/10-12min, and holding temperature is controlled at 710 ± 5 ℃, and soaking time is controlled at 20 ± 3min; Quench, at 15-20 ℃/6-8min, holding temperature is controlled at 840 ± 2 ℃ in vacuum oven internal heating speed control, and soaking time is controlled at 35 ± 2min, goes into quenching oil when charging into high pure nitrogen to 0.056MPa and stirs 12min; Clean cooling with aqueous rust preventive; Tempering in tempering stove, holding temperature are controlled at 420 ± 5 ℃, and soaking time is controlled at 190 ± 10min, oil dripping 3-5min, and air cooling is to room temperature; Clean with gasoline after the tempering.Hardness of the present invention reaches HRC37-48, and with 2 grades of tests of U.S. ASTM4169 truck vibrations standard, support ruptured after 6 hours, and long service life has been eliminated hidden danger.
