Abstract
A 2-in-1 machining way for a narrow thin-wall bearing ring. Wherein, a blank of two narrow thin-wall bearing ring is clamped integrally on a chuck of a lathe, the I.D., O.D., ends of the blank are turned, chamfered, then heat treatment is carried; after heat treatment, grinding is carried out; after that, the two bearing rings are cut apart. The specific machining procedures are: clamping and positioning one end of a forged and preliminarily formed blank, turning and chamfering the end face, ID, OD of another end; then changing another end for positioning and clamping, turning and chamfering the end face, ID, OD; carrying out heat treatment, grinding after heat treatment; cutting along the cutting interface, finishing the cut at the cutting interface; carrying out aging treatment. The invention solves the problem of warpage and deformation at hardening of narrow thin-wall bearing rings, improves the production efficiency and improves the utilization rate of raw materials.
Description
Technical field:
The present invention relates to design bearing and manufacturing technology field, particularly a kind of two-in-one method for processing narrow series thin-wall bearing ferrule.
Background technique:
At present, for narrow series thin-wall bearing ferrule, the general processing method machine shaping of adopting single independently lasso, because easily buckling deformation when thin-wall bearing ferrule quenches in producing, influence the quality and the precision of following process finished product, so usually increase by an auxiliary stub bar in the thin-wall bearing ferrule blank lower end of processing, treat after the first fine finishing that stub bar is removed in cutting again, thereby reduce distortion, but this method is when reducing amount of deformation, caused raw-material waste greatly, manufacturing efficiency is also lower.
Summary of the invention:
For overcoming the defective that exists in the prior art, the invention provides a kind of two-in-one method for processing narrow series thin-wall bearing ferrule.It adopts the fit method for processing of two narrow series thin-wall bearing ferrules, has solved the problem of easy buckling deformation when narrow series thin-wall bearing ferrule quenches, and has improved manufacturing efficiency, has improved utilization rate of raw materials.
For achieving the above object, the present invention adopts following technological scheme:
Described two-in-one method for processing narrow series thin-wall bearing ferrule earlier closes two narrow series thin-wall bearing ferrules on the chuck that the forging integral installation is clipped in lathe, and turning is circle, cylindrical, end face, chamfering in it, heat-treats then; After the heat treatment circle, cylindrical, end face in it are carried out grinding, after the machine shaping with two bearing ring cutting and separating.
Described two-in-one method for processing narrow series thin-wall bearing ferrule, its machining process is: two narrow series thin-wall bearing ferrules are closed be swaged into a blank material, turning adds the blank raw material elder generation one end clamping location that will forge preliminarily forming man-hour, and turning the other end end face, inside diameter surface, external diameter surface also carry out chamfered; The clamping that replaces then location, turning end face, inside diameter surface, internal diameter cut off the oral groove groove and carry out chamfered; And then, after the heat treatment its end face, inside diameter surface, external diameter surface are carried out grinding fine finishing through Overheating Treatment; Last edge is cut incision position and is cut off, and a fine finishing cut-out mouthful section, carries out ageing treatment.
Owing to adopted aforesaid technological scheme, the present invention has following good effect:
This two-in-one method for processing narrow series thin-wall bearing ferrule, width when this method is equivalent to increase ring quenching, the buckling deformation amount when both having reduced to quench has improved raw-material utilization ratio again, because of the fit processing of two lassos, improved manufacturing efficiency greatly simultaneously.As in actual production, a narrow serial thin-wall bearing outer ring external diameter φ 345mm, width 18mm, effective thickness 4mm.Warpage 1.8mm after single processing is quenched adopts two-in-one processing method quenching back warpage 0.5mm.Normal two these bearing ring external diameters of Vehicle Processing take 1.5 hours, adopt two-in-one processing method to take 0.6 hour; Two these bearing ring external diameters of normal corase grind take 2.4 hours, adopt two-in-one processing method to take 1.5 hours; Efficient has improved one times nearly.Needing width when adopting two these bearing rings of the auxiliary stub bar method of increase to quench is 59.8mm, and adopting two-in-one processing method is 42.5mm, shifts forging thus onto, and its raw-material utilization ratio will improve more than 50%.
This method is when forging, these two narrow series thin-wall bearing ferrules are closed be swaged into a blank material (abbreviation closes forging), not involutory forging cuts, and directly this compound body is carried out all process steps processing (being called for short fit processing), after machine shaping, carry out cutting and separating again.Separating the back only needs its section is finish grinded processing, can obtain two bearing ring finished products.It adopts the fit method for processing of two narrow series thin-wall bearing ferrules, has solved the problem of easy buckling deformation when narrow series thin-wall bearing ferrule quenches, and has improved manufacturing efficiency, has improved utilization rate of raw materials.
Description of drawings:
Fig. 1 is two-in-one narrow series thin-wall bearing ferrule structural representation;
Number in the figure: 01-bearing ring; 02-cuts off the oral groove groove; The 03-bearing ring.
Embodiment:
As shown in fig. 1, this two-in-one method for processing narrow series thin-wall bearing ferrule, its method is carried out cutting and separating after being meant the fit machine shaping of two narrow series thin-wall bearing ferrule blank material again.Its machining process is: two narrow series thin-wall bearing ferrules are closed be swaged into a blank material, turning adds the blank raw material elder generation one end clamping location that will forge preliminarily forming man-hour, and turning the other end end face, inside diameter surface and whole external diameter surface also carry out chamfered; The clamping that replaces then location, turning end face, inside diameter surface, internal diameter cut off the oral groove groove and carry out chamfered; Again through Overheating Treatment, first each forming surface of fine finishing; Cut off oral groove groove (02) along internal diameter at last and locate to cut off, and a fine finishing cut-out mouthful section, carry out ageing treatment.Thereby produce two bearing rings (01,03) simultaneously.
