Abstract
The invention discloses a casting method of a rim and spoke assembly. The method comprises the following steps of: first, smelting No. 45 steel into molten steel in an induction electric furnace; and then, after deslagging the molten steel, adding 0.38 to 0.50 weight percent of carbon, less than or equal to 0.60 weight percent of silicon, 0.5 to 0.90 weight percent of manganese, less than or equal to 0.04 weight percent of phosphorus and less than or equal to 0.04 weight percent of sulphur into the molten steel, casting the molten steel and the components into the rim and spoke assembly, keeping the temperature of the rim and spoke assembly, and gradually cooling the rim and spoke assembly to 600 DEG C from the kept temperature to finally obtain a blank of the rim and spoke assembly. The casting method has the advantages of guaranteeing the product size and meeting the requirement of form and position tolerance, along with simple process and the like.
Description
Affiliated technical field the present invention relates to a kind of preparation method of automotive rim, particularly relates to a kind of casting method of rim and spoke assembly.
Background technology is present; A kind of like this preparation method of rim and spoke assembly is disclosed on the market; Its constructional feature is: partly be made up of wheel rim and spoke two, its job operation is: spoke be through towards auxiliary hole, pull and stretch, towards macropore, finishing inner plane, towards bolt hole, towards slotted hole, mill circular arc, turning-off end face, car endoporus and form towards breach; Wheel rim is through rolling up circle, butt welding, rolling shape and expansion forms; And then wheel rim and spoke press-fited circumferential weld, the outer circumferential weld of weldering in a little solid, run-out tolerance and assembling height detection, the weldering, remove breach waste material, car outerplanar, car inner plane, kinetic balance detection and spot welding balancing patch and be processed into rim and spoke assembly; Therefore; This method operation is more loaded down with trivial details, is prone to the error of increasing accumulation, rim and spoke assembly size and Geometrical Tolerance Principle after being difficult to guarantee to press-fit.
Summary of the invention the purpose of this invention is to provide the casting method that a kind of technology is simple, can guarantee the rim and spoke assembly of product size and Geometrical Tolerance Principle.
For achieving the above object, the casting method of rim and spoke assembly of the present invention may further comprise the steps: No. 45 steel are put into be smelted into molten steel in the induction furnace earlier; Then after going out molten steel and removing slag with following each component (weight %) carbon 0.38～0.50, silicon≤0.60, manganese 0.5～0.90; Phosphorus≤0.04, sulphur≤0.04 joins in the molten steel and pours into rim and spoke assembly; Again rim and spoke assembly is incubated processing; Then, be cooled to 600 ℃ gradually, finally obtain the rim and spoke assembly blank by holding temperature.
Said cast negative pressure-0.035MPa～-the 0.060Mpa scope in, top box adopts two-tube bleeding during cast, closes an extraction steam pipe after the cast again.
When ambient temperature more than 20 ℃ the time, its pouring temperature is 1570～1590 ℃; When ambient temperature during at-5～120 ℃, its pouring temperature is 1580～1600 ℃.
Said holding temperature is 850～870 ℃.
The time that is cooled to 600 ℃ from holding temperature gradually was greater than 2 hours.
Owing to change the preparation method of rim and spoke assembly the casting of into V method by Sheet Metal Forming Technology; Again owing in molten steel, added elements such as carbon, silicon, manganese, p and s; Thereby simplified processing technology; Guarantee the size and the Geometrical Tolerance Principle of rim and spoke assembly, guaranteed the product strength and the quality of rim and spoke assembly simultaneously again, improved competitiveness of product.
Below in conjunction with embodiment the present invention is done further detailed description.
