Abstract
The utility model provides a flange yoke forging blank which is integrally formed by a flange plate and lug yokes; a hollow structure is arranged on the flange plate; a closed curve reinforcement rib is arranged at the edge of the hollow structure and is 3-6mm high and 3-6mm wide. The further improvement is that a U-shaped concave part with an outwards opening is arranged at the inner bar corresponding to the outer end parts of the two yoke lugs; the depth of the U-shaped concave part is calculated by reserving a machining allowance of 2-4mm. The weight of each flange yoke forging blank is reduced by more than 23% by arranging the hollow structure and the closed curve reinforcement ribs, and the cost is reduced by more than 23%.
Description
Technical field
The utility model relates to the flange york class part in machinery and car transmissions, especially a kind of flange york rough forging.
Background technique
Traditional flange york rough forging structure, as figure institute 1 shows: pitch 3 two-part by flange plate 1, ear, by the reinforcement boss 2 that has curvature of the spinal column shape on flange plate 1.The feature of this flange york is that Heavy Weight, cost are high.Current require automotive light weight technology and fall cost in the situation that, necessaryly carry out innovative design.
Summary of the invention
The utility model proposes a kind of flange york rough forging, object is to ensure, under flange york part strength and the prerequisite in working life, to reduce own wt, reducing production costs.
The technical solution of the utility model is: a kind of flange york rough forging, form an entirety by flange plate, ear fork two-part, it is characterized in that: flange plate is provided with hollow structure, be provided with closed curve stiffening rib at the edge of hollow structure, the height of closed curve stiffening rib is 3-6 millimeter, and the width of closed curve stiffening rib is 3-6 millimeter.
Further improvement to technique scheme: the home records corresponding to two fork ear outer ends are provided with outwardly open " U " shape depression, U " degree of depth of shape depression to be to also have machining allowance 2-4 millimeter to calculate.
The beneficial effects of the utility model: the utility model is by the setting of hollow structure and closed curve stiffening rib, and every loss of weight is more than 23%, cost-saving more than 23%.
Brief description of the drawings
Fig. 1 is traditional common flange york rough forging structural drawing.
Fig. 2 is a kind of flange york rough forging of the utility model structural drawing.
Fig. 3 is the generalized section of closed curve stiffening rib.
Fig. 4 is the shearing stress in torsion power distribution map of filled circles sectional axis.
Embodiment
A kind of flange york rough forging as shown in Figure 2 and Figure 3, pitch 3 two-part by flange plate 1, ear and form an entirety, flange plate is provided with hollow structure 4, be provided with closed curve stiffening rib 5 at the edge of hollow structure, the height of closed curve stiffening rib is 3-6 millimeter, and the width of closed curve stiffening rib is 3-6 millimeter.
As shown in Figure 2, being provided with outwardly open " U " shape depression 6, U corresponding to the home records of two fork ear outer ends " degree of depth of shape depression to be to also have machining allowance 2-4 millimeter to calculate.
As shown in Figure 4, the utility model is according to engineering mechanics principle---the shearing stress in torsion power regularity of distribution of round bar solid section axle; In the time that the maximum shear stress of section edges reaches allowable shear stress, near the center of circle, each point place shearing stress is very little, in order rationally to utilize material, material should be placed on to the part away from the center of circle, makes hollow.
Use above mentality of designing, a kind of flange york is carried out improving in detail design, concrete outcome is as follows: flange york rough forging weight is originally 8.8kg, and the heavy 6.8kg of newly-designed blank, has reduced 2kg.
Do breaking test: when former flange york 33000N.m, twist off, and the flange york of hollow needs 40520N.m just to twist off; Do fatigue strength experiment: load the power of 19000N.m moment of torsion, former flange york has moved 210,000 times and cracked, and the flange york of hollow 300,000 times are moved and also there is no crackle.
Claims (2)
