Abstract
The invention discloses a method for manufacturing a hollow shaft of a vehicle rear axle reducer, belonging to the field of vehicle part processing. In the invention, a hollow tubular blank is cast and molded once by utilizing a centrifugal casting technology, and then the surface of the blank is machined and processed. The method is convenient for processing and manufacturing and can effectively save materials and reduce the cost.
Description
Technical field
The invention belongs to auto parts machinery and make the field, relate in particular to a kind of manufacture method of automotive rear axle speed-reducing device hollow shaft.
Background technology
Hollow shaft is one of employed connector on the automobile axle, and its main body is hollow tubular, is processed with spline tooth on the outer wall.Because the desired material of hollow shaft requires than higher, therefore, processing method commonly used all is to use the bigger round steel of diameter to hole earlier, and then the spline tooth of finished surface, so not only the unusual trouble and also can cause a large amount of steel to waste in the process of the boring and the spline tooth of finished surface of boring makes that the cost of whole hollow shaft is very high.Next complete hollow shaft weight of normal conditions is about 3kg, and about needing the round steel weight use as 7kg, directly waste is up to about 4kg, and this all is very big loss for manufacturer not only, also can produce very big influence for consumers.
Summary of the invention
Purpose of the present invention just is to provide a kind of manufacture method of automotive rear axle speed-reducing device hollow shaft, can effectively solve existing hollow shaft processing trouble, cost height, problem that loss is big.
To achieve these goals, the technical solution used in the present invention is such: a kind of manufacture method of automotive rear axle speed-reducing device hollow shaft, and this method may further comprise the steps:
At first,, and it is gone into the stove fusing, refine into molten steel according to the component ratio of the required steel of hollow shaft configuration raw material;
Secondly, the molten steel that refining is good adds in the mould of centrifuge, and adopting centrifugal casting technique is the hollow tubular blank with the molten steel one-shot forming;
Then, by the blank Surface Machining spline tooth at casting such as milling machine, lathe;
At last, polished in the hollow shaft surface that processes and polish.
Further, two parts before and after its length direction of mould inner wall flat edge of described centrifuge is divided into, and two-part diameter difference is 0.5-1cm.
Compared with prior art, the invention has the advantages that: not only manufacturing and easy to process, and adopt centrifugal casting technique to save cost more, can directly reduce the steel waste about 2.5kg, bring the decline of about 15 yuan of costs, not only reduced waste but also be more suitable for consumer's requirement; Two parts before and after its length direction of mould inner wall flat edge of described centrifuge is divided into, and two-part diameter difference is 0.5-1cm make the blank outer surface after the moulding also be front and back two parts that the diameter difference is 0.5-1cm, further save cost.
Description of drawings
Fig. 1 is the cutaway view of centrifuge mould used herein;
Fig. 2 is the cutaway view of the blank of casting;
Fig. 3 is the product structure schematic diagram after machining.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, Fig. 2 and Fig. 3, a kind of manufacture method of automotive rear axle speed-reducing device hollow shaft, this method may further comprise the steps:
At first,, and it is gone into the stove fusing, refine into molten steel according to the component ratio of the required steel of hollow shaft configuration raw material;
Secondly, the molten steel that refining is good adds in the mould of centrifuge, and adopting centrifugal casting technique is hollow tubular blank 1 with the molten steel one-shot forming;
Then, by the blank 1 Surface Machining spline tooth 2 at casting such as milling machine, lathe;
At last, polished in the hollow shaft surface that processes and polish.
Two parts before and after its length direction of mould inner wall flat edge of described centrifuge is divided into, and two-part diameter difference is 0.5-1cm, 1 outer surface of the blank after the moulding also is front and back two parts that the diameter difference is 0.5-1cm like this, further saves cost.
