Abstract
The utility model discloses a novel universal joint fork forged piece of a transmission shaft. The novel universal joint fork forged piece comprises a connection hub and two fork lugs which are symmetrically arranged; a connection rib is arranged between the two fork lugs; a concave groove is formed between the connection rib and the connection hub; the outer circle of the connection hub is of a step-shaped tapered structure; and the center of the bottom of the concave groove sinks inwards the connection rib to form a pit. With the adoption of the technical scheme, the outer circle of the connection hub is of the step-shaped tapered structure, the weight of the forged piece is lightened, the cost of production is lowered, and the cutting allowance of metal is reduced. The center of the bottom of the concave groove sinks inwards the connection rib to form the pit, so that the thickness of the connection rib is reduced, and correspondingly, the weight of the forged piece is lightened and the cost of production is lowered; and the novel universal joint fork forged piece is more energy-saving and consumption-reducing when the novel universal joint fork forged piece is forged by medium-frequency induction heating.
Description
Technical field
The utility model belongs to the automotive industry technical field, is specifically related to a kind of novel driving shaft universal joint fork forging.
Background technique
Employed traditional driving shaft universal joint fork forging structural type is as shown in Figure 1 on the automobile, comprises connecting hub 1 and symmetrically arranged two fork ears 2.Two-dot chain line is the universal-joint fork finished product after the gold machining among Fig. 1, is cone structure owing to connect the cylindrical of hub 1, and the metal cutting surplus during gold machining is big; Because two connecting tendon 3 thickness of pitching between the ear 2 are thicker, the longitudinal section, groove 4 bottom that promptly connects in the hub 1 is the circular arc line segment structure, and this just relatively wastes raw material.And shortcoming such as energy consumption height when underway frequency induction heating forges.
The model utility content
The utility model is in order to solve deficiency of the prior art, the novel driving shaft universal joint fork forging that provide a kind of and save material, the gold machining bite is little, energy consumption is little.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: novel driving shaft universal joint fork forging; Comprise and connect hub and symmetrically arranged two fork ears; Two forks are provided with connecting tendon between the ears, and connecting tendon forms groove, the cone structure that the cylindrical of said connection hub is stepped with being connected between the hub.
Said bottom portion of groove mediad connecting tendon sunken inside forms pit.
Adopt technique scheme, connect the stepped cone structure of cylindrical of hub, alleviate the weight of forging, reduce production costs, and reduce the metal cutting surplus.Bottom portion of groove mediad connecting tendon sunken inside forms pit, and promptly connecting tendon thickness reduces, and the so also corresponding weight that alleviates forging reduces production costs, and more energy-saving and cost-reducing when Frequency Induction Heating is forged.
Description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is the structural representation of the utility model.
Embodiment
As shown in Figure 2; The novel driving shaft universal joint fork forging of the utility model; Comprise and connect hub 1 and symmetrically arranged two fork ears 2; Two forks are provided with connecting tendon 3 between the ears 2, connecting tendon 3 with is connected formation groove 4 between the hub 1, the stepped cone structure (a-quadrant among Fig. 2) of cylindrical of connection hub 1.Groove 4 bottom central form pit 5 (B zone among Fig. 2) to connecting tendon 3 sunken insides.Two-dot chain line is the universal-joint fork finished product after the gold machining among Fig. 2.
Below illustrate the utility model with respect to the beneficial effect that is reached before improving:
1,Weight reduction, saving cost aspect: driving shaft universal joint fork single-piece cutting stock weight shown in Figure 1 is 8.9Kg, and the single-piece forge weight is 7.8Kg, driving shaft universal joint fork single-piece cutting stock weight 8.4Kg shown in Figure 2; Single-piece forge weight 7.3Kg; See that from the aspect that saves material the single-piece cutting stock weight has reduced 0.5Kg, every Master Cost is practiced thrift 2 yuans; This product is by 200,000 of annual consumptions, and raw material can be practiced thrift 400,000 yuan/year.
2,Energy-saving and cost-reducing aspect: calculate from the energy consumption of heating blank; Adopt Frequency Induction Heating; The about 0.5Kw.h of per kilogram blank heating energy consumption (0.5 degree); Every saving power 0.25 degree, can practice thrift the electricity charge every year: * 20 ten thousand=3.25 ten thousand yuan of * 0.65 yuan/degree of 0.25 degree, the electricity charge are practiced thrift 3.25 ten thousand yuan/year.
3,Reduce the machining allowance aspect: machining allowance is bigger among Fig. 1, and shown in the a-quadrant among Fig. 2, machining allowance is quite little, and the utility model has improved the manufacturing efficiency of gold machining greatly, has practiced thrift the gold machining cost of charp tool.
By on can learn: 1 universal-joint fork of every production reduces cost: more than 2.16 yuan.
Below only be to be example with certain driving shaft universal joint fork, the driving shaft universal joint fork that adopts this kind forging structure is all within the protection domain of the utility model.
