Abstract
The invention relates to a rear axle half-axle sleeve structure of an automobile and a machining process thereof. The structure is characterized in that a seamless steel tube is taken as a main body of a half-axle sleeve; an oil seal sleeve (2) is pressed on an inner oil seal table (4) of the rear axle tube (1); and a flange (3) is sleeved on the oil seal sleeve (2). The machining process comprises the following steps: (1) carrying out blanking for a tube blank of the rear axle tube and adopting the seamless steel tube as a raw material; (2) carrying out hardening and tempering for the half-axle sleeve; (3) completing shot blast for the half-axle sleeve; (4) carrying out rough turning of the inner oil seal table on the half-axle sleeve; (5) pressing the oil seal sleeve on the inner oil seal table of the half-axle sleeve; (6) welding the half-axle sleeve and the oil seal sleeve on an upper body and a lower body of an axle housing; (7) pressing a ring flange on the oil seal sleeve; (8) realizing girth welding of the ring flange; and (9) carrying out subsequent rough machining and finish machining of a bearing table of the half-axle sleeve and eliminating machining allowance. The rear axle housing tube structure has reasonable structure, easy machining, high production efficiency and low cost.
Description
Technical field
The present invention relates to the main attaching parts of automobile axle--the structure and the processing technology thereof of vehicle rear-axle housing axle tube.
Background technology
The structure that the present vehicle bridge industry of axle tube generally adopts is the solid forging structure, as accompanying drawing 4, shown in Figure 5, because of it adopts round steel blanking, thereby, the part that the forging blank need remove in the course of processing is bigger, 10 is the axle tube assembly among the figure, and 9 for forging the part that blank need remove, and 4 need remove part for the inner oil seal platform.This shows existing rear axle half-axle sleeve assembly, material cost height in the course of processing, fabrication cycle is long, the processing technology complexity, concrete manifestation is as follows:
1. the high aspect of material cost: because Forging Technology requires the product stock left for machining bigger, account for 52% of workpiece gross weight generally for mach surplus, promptly stock utilization has only 48%, causes the unnecessary waste of material, and forges blank price height.
2. fabrication cycle is rectangular: Forging Technology is the lower job operation of a kind of efficient, and the forging mold requirement is high, and service life is low, causes the workpiece cost significantly to improve.
3. the complicated aspect of processing technology: its main manufacturing procedure is: 1. axle tube round steel blanking; 2. axle tube die forging processing; 3. axle tube normalizing; 4. axle tube ball blast; 5. the short end of rough turn processing (with the bridge tube coupling end); 6. the rough turn section chief's end (with the wheel hub coupling end) that adds; 7. prtreatment endoporus; 8. prtreatment inner oil seal platform; 9. fine limit work endoporus; 10. mill the flat position of processing; (11) body and axle tube assembly welding about the axle housing; (12) carry out thick, the fine limit work axle tube bearing stand operation of postorder.Technical requirements is higher in its course of processing: 1. forging blank difficulty is bigger, the unit price height; 2. it is big to forge the blank machining allowance, has increased machining period greatly.
Above reason causes the product price of prior art higher, market competitiveness wretched insufficiency.
Summary of the invention
The objective of the invention is to want to overcome above-mentioned the deficiencies in the prior art, a kind of improved rear axle half-axle sleeve structure of automobile is provided, and its processing technology is provided, this axle tube is rational in infrastructure, is easy to processing, the production efficiency height, and cost is low.
For realizing that the technical scheme that above-mentioned purpose of the present invention adopts is: a kind of rear axle half-axle sleeve structure of automobile, its constructional feature be with solid drawn pipe as the axle tube main body, on the axle tube main body, press-fit oil-sealing sleeve, on oil-sealing sleeve, press-fit flange.
1., to the blanking of axle tube pipe embryo the processing technology of rear axle half-axle sleeve structure of automobile of the present invention is as follows:, raw material adopts solid drawn pipe; 2., axle tube is carried out modifier treatment; 3., to the axle tube ball blast; 4., rough turn inner oil seal platform on axle tube; 5., on axle tube, press-fit oil-sealing sleeve; 6., with axle tube, oil-sealing sleeve assembly welding on the upper and lower body of axle housing; 7., on oil-sealing sleeve, press-fit flange; 8., boxing flange; 9., carry out thick, the fine limit work axle tube bearing stand operation of postorder, and remove stock left for machining.
The present invention press-fits oil-sealing sleeve owing to adopted the main body of solid drawn pipe as axle tube on axle tube, press-fit the structure of flange on the oil-sealing sleeve again, enhances productivity greatly, has reduced productive costs, and concrete manifestation is as follows:
1. aspect that the cost of material is low: owing to adopt the tubing technology for blanking, stock left for machining is little, accounts for 10% of workpiece gross weight generally for mach surplus, and stock utilization significantly improves.
2. fabrication cycle is lacked the aspect: the tubing technology for blanking is the high job operation of a kind of efficient, and tubing production, convenient transportation are easy to management, adopts the blanking of sawing machine S. A., and efficient is largely increased.
3. the simple aspect of processing technology: according to processing technology of the present invention, the more existing Forging Technology of each procedure is compared, and operation is few, and operation is simple, for reliable conditions has been created in the raising of the conveyor line quality of production and quantity.

The specific embodiment
Below in conjunction with the concrete example of implementing the present invention is done further detailed description.
By Fig. 1, Fig. 2 as can be seen, rear axle half-axle sleeve structure of automobile of the present invention, be with solid drawn pipe as the axle tube main body, on axle tube 1, press-fit an oil-sealing sleeve 2, on oil-sealing sleeve 2, press-fit flange 3.Its processing technology is as follows:
The first step, to the blanking of axle tube pipe embryo, raw material adopts the 45# solid drawn pipe; In second step, adopt the mode that increases temperature tempering of quenching earlier that axle tube is carried out modifier treatment; In the 3rd step,, remove oxide skin to the axle tube ball blast; The 4th step, rough turn inner oil seal platform 4 on axle tube 1; In the 5th step, on axle tube 1, press-fit oil-sealing sleeve 2; The 6th the step, with axle tube 1, oil-sealing sleeve 2 assembly weldings on the upper and lower body 7,8 of axle housing shown in Figure 4; In the 7th step, on oil-sealing sleeve 2, press-fit flange 3; The 8th step, on oil-sealing sleeve 2, carry out gas along the periphery of flange 3 and protect weldering 5, flange 3 is securely fixed on the oil-sealing sleeve 2; In the 9th step, carry out thick, the fine limit work axle tube bearing stand operation of postorder, and remove the stock left for machining 6 shown in Fig. 3.
Can further find out the significant difference of the present invention and prior art from Fig. 1, Fig. 2, Fig. 3 and Fig. 5, Fig. 6, compared with prior art, processing technology of the present invention is simple, and productive costs is low, has tangible substantive distinguishing features and obvious improvement.
