Abstract
The utility model discloses a light-weight end tooth middle flange forge piece of a transmission shaft. The light-weight end tooth middle flange forge piece comprises a disk part and a barrel part which are coaxial, wherein a first gap, a second gap, a third gap and a fourth gap are uniformly formed in the circumferential edge of the disk part along the circumferential direction; the first gap and the third gap are symmetrically formed; the second gap and the fourth gap are symmetrically formed; the widths of the third gap and the fourth gap are larger than those of the first gap and the third gap. Due to the technical scheme, the circumferential edge of the disk part of the light-weight end tooth middle flange forge piece is directly forged to form the first gap, the second gap, the third gap and the fourth gap, so that the disk part has a flower-disk-shaped structure, the cutting weight of single forge pieces and the weight of each single forge piece are reduced, raw materials are saved, and the consumption is reduced; due to medium-frequency induction heating, heating energy consumption is alleviated.
Description
Technical field
The utility model belongs to automotive industry technical field, is specifically related to a kind of lightweight transmission shaft end tooth middle lug forging.
Background technique
At present, traditional transmission shaft end tooth middle lug forging as depicted in figs. 1 and 2, comprise homoaxial dish portion 1 and cylinder portion 2, dish portion 1 is round structure, and this structure not only increases amount of finish, and serious waste material, virtually just improved the manufacture cost of such part, restricted the raising of manufacturing efficiency, particularly because price of steel product in recent years skyrockets, energy-saving and cost-reducing, the to improve material top priority in face of Shi Bai enterprise of utilizing.
Model utility content
The utility model is in order to solve deficiency of the prior art, provides a kind of and saves material, energy-saving and cost-reducing lightweight transmission shaft end tooth middle lug forging.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: lightweight transmission shaft end tooth middle lug forging, comprise homoaxial dish portion and cylinder portion, the circumferential edges of described dish portion is along being circumferentially evenly provided with the first breach, the second breach, the 3rd breach and the 4th breach, the first breach and the 3rd breach are symmetrical arranged, the second breach and the 4th breach are symmetrical arranged, and the width of the 3rd breach and the 4th breach is greater than the width of the first breach and the 3rd breach.
The bottom of described the first breach and the 3rd breach is radially respectively equipped with the projection of a taper, the first breach and the 3rd breach be all the cone structure that outer imperial palace is little.
Described the second breach and the 4th breach form by outside conical section and inner cambered surface section, and conical section is the structure that outer imperial palace is little, the equal diameters of the diameter of described cambered surface section and conical section smallest end end face.
Adopt technique scheme, the utility model directly forges out the first breach, the second breach, the 3rd breach and the 4th breach by the circumferential edges of dish portion, make dish portion be floral disc shape and structure, has alleviated single-piece forging cutting stock weight and single-piece forge weight, saved raw material, reduced and consume; When by Frequency Induction Heating, reduce heating energy consumption, energy-conservation.The shape and structure when shape and structure of the first breach, the second breach, the 3rd breach and the 4th breach becomes product with forging process is consistent, thereby has reduced the amount of finish of subsequent handling.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is that the central B-B of Fig. 1 is to sectional view;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is that the central A-A of Fig. 3 is to sectional view.
Embodiment
As shown in Figure 3 and Figure 4, lightweight transmission shaft end tooth middle lug forging of the present utility model, comprise homoaxial dish portion 1 and cylinder portion 2, the circumferential edges of dish portion 1 is along being circumferentially evenly provided with the first breach 3, the second breach 4, the 3rd breach 5 and the 4th breach 6, the first breach 3 and the 3rd breach 5 are symmetrical arranged, the second breach 4 and the 4th breach 6 are symmetrical arranged, and the width of the 3rd breach 5 and the 4th breach 6 is greater than the width of the first breach 3 and the 3rd breach 5.
What the bottom of the first breach 3 and the 3rd breach 5 was radially respectively equipped with projection 7, the first breach 3 of a taper and the 3rd breach 5 is all the cone structure that outer imperial palace is little.
The second breach 4 and the 4th breach 6 form by outside conical section 8 and inner cambered surface section 9, and conical section 8 is the structure that outer imperial palace is little, the equal diameters of the diameter of described cambered surface section 9 and conical section 8 smallest end end faces.
Below illustrate this practical lightweight with respect to the beneficial effect reaching before improving:
1, weight reduction, cost-saving aspect: existing transmission shaft end tooth middle lug forging as depicted in figs. 1 and 2, single-piece forge weight is 6.05Kg; The utility model as shown in Figure 3 and Figure 4, single-piece forge weight 5.5Kg, from the aspect that saves material, single-piece forge weight has reduced 0.55Kg, 4000 yuan of steel per ton, save 2.2 yuans, 70,000 of the every annual consumptions of these series product for every, save material 38.5 tons, reduce by 15.4 ten thousand yuan/year of cost of material.
2, energy-saving and cost-reducing aspect: calculate from the energy consumption of heating blank, adopt Frequency Induction Heating, the about 0.5Kw.h(0.5 degree of per kilogram blank heating energy consumption), every saving power 0.275 degree, every year can power cost saving: 0.275 * 0.65 yuan of degree/* 7 ten thousand=12512.5 yuan of degree, the electricity charge are saved 12512.5 yuan/year.
Below be only that certain heavy transmission shaft in series end tooth middle lug forging is example, as from the foregoing, adopting the utility model is to improve material use, and realizes and saving energy and reduce the cost, reduction cost of material.
