Description
Technical field
The utility model belongs to technical field of bearings, is particularly related to the net-size forging of a kind of Lightweight car wheel hub flange mandrel.
Background technique
Flange mandrel is the constituent elements of automotive hub, not only bears thrust load but also bear radial load, is the strength member of carload and rotation.
Owing to having, productive temp is fast, formed precision is high, can realize the advantages such as near-net-shape, cost of production is low, environmetal impact is little in forging at a high speed, is widely applied at automobile gearbox component, bearing industry.
Because the flange wall thickness of Lightweight car wheel hub flange mandrel is usually at 3 ~ 11mm, and for the product of below 8mm, exists when high speed and precision forging molding always and transmit unstable, produce unstable, the problems such as manufacturing efficiency is low.Usually the thickness increasing clamp face is needed in order to solve the problem, if but increase end face integral thickness, to forging, Yan Zexu increases a large amount of materials consumptions, corresponding cost of production also improves greatly simultaneously, comprise for rear road Vehicle Processing operation, the increase of surplus, means that the turning time lengthens, efficiency reduces, turning cost increase.
Therefore, the transmission stability problem of solution thin flange mandrel net-size forging at high speed and precision forging equipment is needed badly.
Model utility content
The purpose of this utility model is to overcome the above-mentioned defect mentioned and deficiency, and provides a kind of Lightweight car wheel hub flange mandrel net-size forging net-size forging.
The technological scheme that the utility model realizes the employing of its object is as follows.
The net-size forging of a kind of Lightweight car wheel hub flange mandrel, comprises the neck flange, stiffening rib and the flange plate that are wholely set; Described stiffening rib is arranged on the joint of neck flange and flange plate; The outer circumference face of described flange plate is provided with a circle bulge loop; The circumferential surface of described bulge loop and the circumferential surface of flange plate flush; The cross section of described bulge loop is at right angles trapezoidal, and the hypotenuse of described bulge loop cross section and the axis of flange mandrel are 150 ° ~ 170 ° angles of cut.
Described stiffening rib has 4, and axially arranges; The angle of cut of adjacent said rib is 90 °.
Described neck flange is provided with the first raceway groove and the second raceway groove from top to bottom; The diameter of described first raceway groove is less than the second raceway groove.
The joint chamfering of described neck flange and flange plate is arranged.
Recess is provided with in the middle part of the exterior edge face of described flange plate.
The hypotenuse of described bulge loop cross section and the axis of flange mandrel are 160 ° of angles of cut; The width of the right angle waist of described bulge loop cross section is 2mm; The width of the upper base of described bulge loop cross section is 2mm.
The net-size forging of this Lightweight car wheel hub flange mandrel, on the one hand the thickness of neck flange and flange plate is cut thin, the intensity of flange mandrel is increased by stiffening rib, significantly reduce the weight of flange mandrel, save raw material dosage, on the other hand, by arranging a circle bulge loop on the outer circumference face of flange plate, add the surface of contact of precision forging process mechanism hand and flange mandrel, make manipulator clamping more stable, overcome because manipulator clamping is unstable and shake caused sensor alarm, and metal fluidity when improve forging, improve the mechanical property of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view in A-A face in Fig. 1;
In figure: 1-neck flange, 1a-first raceway groove, 1b-second raceway groove, 2-stiffening rib, 3-flange plate, 3a-bulge loop, 3b-recess.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The net-size forging of a kind of Lightweight car wheel hub flange mandrel, comprises the neck flange 1, stiffening rib 2 and the flange plate 3 that are wholely set; Described stiffening rib 2 is arranged on the joint of neck flange 1 and flange plate 3; The outer circumference face of described flange plate 3 is provided with a circle bulge loop 3a; The circumferential surface of described bulge loop 3a and the circumferential surface of flange plate 3 flush; The cross section of described bulge loop 3a is at right angles trapezoidal, and the described hypotenuse of bulge loop 3a cross section and the axis of flange mandrel are 150 ° ~ 170 ° angles of cut.
As preferably, the described hypotenuse of bulge loop 3a cross section and the axis of flange mandrel are 160 ° of angles of cut; The width of the right angle waist of described bulge loop 3a cross section is 2mm; The width of the upper base of described bulge loop 3a cross section is 2mm.
The setting of bulge loop 3a, the clamp face that flange mandrel is transmitted when high speed and precision forges is increased, thus also advantageously in the flowing forming of metal while raising mechanism hand transmits stability, make flange mandrel application high speed and precision forging molding, meet the requirement of automobile industry for the type quality of product and production capacity, overcome flange mandrel and there is the technical barriers such as reject rate is high, manufacturing efficiency is low when forging always
Described stiffening rib 2 has 4, and axially arranges; The angle of cut of adjacent said rib 2 is 90 °.Because the requirement of automobile market to reduction of discharging and oil consumption is more and more higher, the development of hub bearing also goes development towards lightweight, so flange plate 3 thickness becomes local by stiffening rib 2 to meet requirement of strength from original uniform thickness, the thinning requirement having reached weight reduction of all the other part thickness.
