specific Embodiment approach 1

[0022] Specific embodiment one: the present embodiment adopts liquid die forging to produce the technological method step of automobile air conditioner rocking plate as follows:

[0023] Step 1. Mold design and molding:

[0024] According to the structure, shape, size and performance requirements of the car air conditioner rocker plate, the punch and die liquid forging dies for the car air conditioner rocker plate are designed. The design of the punch 3 and die 6 of the swinging plate of the automobile air conditioner should fully consider the influence of the mold material, clearance, demoulding slope, and exhaust. The five concave holes of the swinging plate of the automobile air conditioner are the transmission power surface , the machining allowance is enlarged by 1.0mm, and the demoulding slope is enlarged by 3°; the center hole is enlarged by 1.0mm due to the need of assembly and fixation, and the rocking plate is designed according to the heat shrinkage of aluminum allo...

specific Embodiment approach 2

[0038] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the temperature of the aluminum alloy liquid in step 3 is 740°C, and the temperature of the liquid forging die when pouring the aluminum alloy liquid into the cavity of the liquid forging die The temperature is 280°C, the pressure applied by the punch to the aluminum alloy liquid poured into the cavity of the liquid forging die is 120Mpa, and the pressure maintenance time is 80s. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0039] Embodiment 3: The difference between this embodiment and Embodiment 1 and Embodiment 2 is that in Step 3, the aluminum alloy liquid is poured at a temperature of 760°C, and the aluminum alloy liquid is in a liquid state when it is poured into the cavity of the liquid forging die. The temperature of the die forging die is 250°C, the pressure exerted by the punch on the aluminum alloy liquid poured into the cavity of the liquid forging die is 140 MPa, and the pressurization maintenance time is 60 s. Other steps are the same as in the first embodiment.

Abstract

A technology for manufacturing the shaking disk of air conditioner for car by liquid-state die forging method includes such steps as designing and manufacturing die, smelting Al alloy, liquid-state die forging and solution ageing. Its advantages are no need of cutting, fine structure and high mechanical performance.

Description

technical field [0001] The invention relates to a processing method for a swing plate of an automobile air conditioner. Background technique [0002] At present, the production of the car air conditioner rocking plate is made by metal mold gravity casting or metal pressure casting, which leads to poor mechanical properties of the car air conditioner rocking plate and cannot meet the requirements of the working environment; The rocking plate of the device has a complicated cutting process, the mold structure cannot be simplified, and the production cycle of the product is long. Contents of the invention [0003] In order to solve the problems of poor mechanical properties of the existing automobile air conditioner rocking plate, unable to meet the requirements of the working environment, complex processing procedures, complex mold structure, and long production cycle of the product, the present invention proposes a method for producing automobile air conditioners using a li...
