Abstract
The invention discloses a method for producing asymmetry dies forging, which according to the structure of single asymmetry dies forging product to produce one symmetry die forging formed by two symmetry connected asymmetry die forging elements, then along the symmetry axle of said symmetry die forging to be divided into two needed asymmetry die forging elements. The inventive method can simplify the process and improve the producing efficiency.
Description
Technical field
The present invention relates to a kind of production method of forging part, is a kind of production of asymmetric forging part specifically.
Background technology
The production of forging part will be considered following factor: the manufacturing and the service life of (1) mould usually; (2) shaping of forging; (3) production efficiency; (4) allowance.
Yet, when being asymmetrical special-shaped structure for forging part to be processed, with forging part illustrated in figures 1 and 2 is example, adopt the mode of a traditional forging part of a Mould Machining, then can there are the following problems: (1) because forging part is a unsymmetric structure, the two ends thin and thick differs, the tonnage difference, cause the mould unbalance stress, will reduce the life-span of mould.(2) because the forging part structure is asymmetric, blank is difficult to steadily put in position adding man-hour, and blank is put the improper shaping that will influence forging part.(3) for the die parting line that makes the forging part two ends at grade, increase allowance.Mode of production production efficiency of (4) one moulds is low.
Summary of the invention
At the forging part mode of production above shortcomings of one of a present mould, the object of the present invention is to provide a kind of production method of novel asymmetric forging part.
A kind of production method of novel asymmetric forging part, it is characterized in that: according to the planform of single asymmetric forging part product, produce a symmetric mode forging that is linked together by two asymmetric forging part symmetries earlier, the symmetry axis cutting along the symmetric mode forging is divided into two required asymmetric forging parts again.
Therefore the present invention will be that the forging part that asymmetrical forging part is combined into symmetry carries out production and processing dexterously originally, cut into two required asymmetric forging parts after finishing again, and this production can produce following beneficial effect:
(1) forging part that connects into a symmetry by two asymmetric forging parts is produced, what add production in man-hour then is a symmetric mode forging that two-end thickness is identical, mold cavity symmetry during die forging, solved the mould unbalance stress problem in the single asymmetric forging part die forging process, the service life of having improved mould.
(2) the easy balance wheel of the blank of Dui Cheng forging part is placed on centre-of-pressure position, makes the easy die-forging forming of forging.
(3) owing to be symmetrical structure, can make disjunctor the forging part two ends die parting line at grade, reduced allowance.
(4) mould is produced two asymmetric forging parts simultaneously, has improved production efficiency.
(5) symmetrical structure is convenient to cut edge, mill and repair because of placing steadily easily.
Description of drawings
Fig. 1 is the structural representation of an asymmetric forging part.
Fig. 2 is the vertical view of Fig. 1.
The symmetric mode forging structural representation of Fig. 3 for connecting into by two asymmetric forging parts shown in Figure 1.
Fig. 4 is the vertical view of Fig. 3.
The specific embodiment
Be described further below in conjunction with the production method of the drawings and specific embodiments asymmetric forging part of the present invention.
Production with the asymmetric forging part of structure shown in Figure 1 is example, and its process is:
(1) to ingot casting and tool and mould heating;
(2) on hydraulic press, forge earlier the strip blank that is fit to production drawing 3, product shown in Figure 4;
(3) then to the strip blank heating;
(4) installing on hydraulic press can production drawing 3 and the mould of forging part shown in Figure 4, the strip forging blank is put into mould carried out mold pressing, obtains the forging part of Fig. 3 and structure shown in Figure 4;
(5) and then carried out side cut, mill repair, fire inspection processing;
(6) heat-treat then and detect a flaw, 100% dozen of hardness;
(7) at last along the axis of symmetry A-A sawing of Fig. 3 and symmetric mode forging shown in Figure 4, being divided into two obtains two asymmetric forging part finished products of structure shown in Figure 1.
Certainly, also can after cutting into two asymmetric forging parts after the mold pressing earlier, cut edge again, mill repair, following process such as fire inspection, heat treatment.
Claims (1)
1, a kind of production method of asymmetric forging part, it is characterized in that: according to the planform of single asymmetric forging part product, produce a symmetric mode forging that is linked together by two asymmetric forging part symmetries earlier, the symmetry axis cutting along the symmetric mode forging is divided into two required asymmetric forging parts again.
