Problems solved by technology

[0003] There are many problems with the silicone oil clutch. On the one hand, when preparing the shell of the silicone oil clutch, the traditional process first casts a shell with a smooth surface, and then performs subsequent machining. The grooves of the shell are all completed during the machining process. In this way, the shell is easy to form casting sand holes on the surface or inside of the casting
On the other hand, the housing of the silicone oil clutch is prone to air holes during preparation, resulting in air leakage between the housing of the silicone oil clutch and the front cover, affecting normal use

Embodiment Construction

[0045] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0046] Such as image 3 Shown, a kind of preparation method of silicone oil clutch housing comprises the following steps:

[0047] S1. Smelting molten steel; put the steel material into the steelmaking furnace for smelting to form molten steel that meets the casting requirements, and provide qualified raw materials for the casting 15. During the smelting process, the volume fraction ratio of new and old materials is 60:40. Slag agent 1‰ (volume fraction), and then smelted to 720°C±10°C.

[0048] S2, pouring molten steel into the forming mold for die-casting; after the male template (movable template 11) and female template (fixed template 21) of the forming mold are closed, the movable mold core 12 fixed on the movable template 11 and fixed on the fixed template 21 The fixed mold core forms a cavity consistent with the shape of the casting 15, and the casting 15 is ...

Abstract

The invention provides a preparation method for a silicone oil clutch housing. The preparation method comprises the following steps that S1, molten steel is smelted; S2, the molten steel is injected into a forming mould for pressure casting; S3, waste at a sprue is removed; S4, the surface of a casting is cleaned till the surface is smooth, and casting burrs are removed; S5, an insert is pressed into the casting; S6, the casting is mechanically machined to form the silicone oil clutch housing; S7, the silicone oil clutch housing is subjected to leakproofness detection; S8, the silicone oil clutch housing which is qualified after a leakproofness test is packaged and sealed for storage. The casting is fabricated through the forming mould, the precision of the casting can be guaranteed, the mechanical machining allowance is reduced, machining efficiency is improved, and meanwhile raw materials can be saved.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing, and in particular relates to a preparation method of a silicone oil clutch housing. Background technique [0002] During the driving process of the car, due to the change of environmental conditions and operating conditions, the thermal condition of the engine is also changing. Therefore, the cooling intensity of the engine must be adjusted at any time. It is very important to adjust the cooling intensity of the engine at any time according to the thermal condition of the engine. Installing a silicon oil fan clutch between the fan pulley and the cooling fan is one of the methods to achieve this adjustment. [0003] There are many problems with the silicone oil clutch. On the one hand, when preparing the shell of the silicone oil clutch, the traditional process first casts a shell with a smooth surface, and then performs subsequent machining. The grooves of the shell are all comple...
