Abstract
The utility model provides a kind of cold rolling mandrel being applied to outer race processing, comprise processing department and the external connection end oral area being positioned at processing department two ends, described processing department is less than the development length of mandrel along short-axis direction along the development length of mandrel short-axis direction, described processing department is the length of shaping outer shroud to be processed along the development length of mandrel long axis direction, described processing department comprises lug boss and is positioned at the depressed part of lug boss both sides, and described depressed area is between described external connection end oral area and described lug boss.By the design adopting the relative mandrel main body of processing department to inside contract, run in kind cold, when outer shroud is rolled, its direction along height can be effectively limited, and then can avoid shaping after outer shroud there is along the direction of height the problem that burr is large and inclination angle is large, therefore the quality of mandrel can be improved.
Description
Technical field
The utility model relates to cold rolling field, particularly, relates to a kind of cold rolling core shaft design.
Background technology
As shown in Figure 1, the spin 30 that traditional bearing usually includes outer shroud 10, inner ring 20 and is arranged between outer shroud 10 and inner ring 20.The side that outer shroud 10 is relative with inner ring 20 is typically designed to groove structure, and then is beneficial to spin 30 and rolls between.Wherein, the main relevant parameters of outer shroud 10 comprises outer diameter D 1, internal diameter D2 and height H.
Outer shroud 10 adopts cold rolling technology shaping usually, depicts the design of the mandrel 110 being currently applied to cold rolling with further reference to Fig. 2 A and Fig. 2 B, Fig. 2 A, and Fig. 2 B depicts the schematic diagram adopting this mandrel processing outer shroud 10.As shown in the figure, the protruding processing department of mandrel 110 is in order to roll the groove structure M formed inside outer shroud 10.When mandrel 110 adopts the structure as Fig. 2 A, in cold rolling to model process, after outer shroud 10 is rolled, easily there is along the direction of height H the problem that burr is large and inclination angle is large in the outer rim of the medial surface of outer shroud 10, have a strong impact on product quality, therefore need consider how to improve this problem by core shaft design.
Utility model content
The utility model provides a kind of cold rolling mandrel being applied to outer race processing, comprise processing department and the external connection end oral area being positioned at processing department two ends, described processing department is less than the development length of mandrel along short-axis direction along the development length of mandrel short-axis direction, described processing department is the length of shaping outer shroud to be processed along the development length of mandrel long axis direction, described processing department comprises lug boss and is positioned at the depressed part of lug boss both sides, and described depressed area is between described external connection end oral area and described lug boss.
In one embodiment, lug boss is 40% to 80% of processing department development length along the length that mandrel long axis direction extends.
In one embodiment, described depressed part adjoins the surface of described external connection end oral area side is inclined-plane.
In one embodiment, described depressed part adjoins the surface of described external connection end oral area side and described mandrel along the angle in the cross section of short-axis direction is 2 degree to 5 degree.
By the design adopting the relative mandrel main body of processing department to inside contract, run in kind cold, when outer shroud is rolled, the outer rim of the medial surface of outer shroud can be effectively limited along direction highly, and then can avoid shaping after outer shroud there is along the direction of height H the problem that burr is large and inclination angle is large, therefore the quality of mandrel can be improved.

Detailed description of the invention
For better the specific embodiment of the present invention being described, be described below with reference to relevant indicators.
Please refer to Fig. 3, Fig. 3 depicts the schematic diagram of mandrel 210 of the present utility model.Be applied to the cold rolling mandrel 210 of outer race processing, its external connection end oral area A2 comprising processing department A1 and be positioned at processing department A1 two ends, processing department A1 is less than the development length D2 of mandrel 210 along short-axis direction along the development length D1 of mandrel 210 short-axis direction, processing department A1 is the length of shaping outer shroud to be processed along the development length L of mandrel 210 long axis direction, processing department A1 comprises lug boss A11 and is positioned at the depressed part A12 of lug boss A11 both sides, and depressed part A12 is between external connection end oral area A2 and lug boss A11.The region of the follow-up mandrel of external connection end oral area A2 system 210 and other arrangement of components of cold rolling equipment, the two ends of external connection end oral area A2 can be formed with the region that screwed lock is tied up.Another easy understand, the statement of this place " along long (short) direction of principal axis of mandrel 210 " is the division done based on Fig. 3 horizontal direction and vertical direction.
In one embodiment, lug boss A11 is 40% to 80% of processing department A1 development length L along the length L1 that mandrel 210 long axis direction extends.
The surface that depressed part A12 adjoins described external connection end oral area A2 side is inclined-plane.In one embodiment, depressed part A12 adjoins the surface of external connection end oral area A2 side and mandrel along the angle α in the cross section of short-axis direction is 2 degree to 5 degree.By the design of the arc surfaced of tool special angle, when outer shroud is rolled, the change in shape trend at its edge can be effectively controlled.
Please consult Fig. 4 further, Fig. 4 depicts the schematic diagram of the mandrel 210 machining bearing outer shroud adopting Fig. 3.By the design adopting processing department A1 relative mandrel 210 main body to inside contract, run in kind cold, when outer shroud 10 is rolled, its direction along height H can be effectively limited, that is its height size can control effectively, and then can avoid shaping after outer shroud there is along the direction of height H the problem that burr is large and inclination angle is large, therefore the quality of mandrel can be improved.
The object of content of the present disclosure is to provide the embodiment about various characteristic sum concept of the present utility model, instead of limits the scope of the invention.Those skilled in the relevant art will recognize, can change in a large number structure described above and change, and not deviate from the scope of the present utility model of claim restriction.
