Abstract
The invention discloses a shaping die core for forging door frame flanges, which belongs to the technical field of mechanical forging and relates to an elliptic shaping die core for annular forgings. The task of the invention is to provide the shaping die core for forging door frame flanges. The die core can ensure that the surface of the elliptic middle cavity structure on a blank is neat and smooth, less uniform chipping allowance is left to subsequent machining, the metal fibers of the blank are continuous, the service life of a mechanical part of the blank is prolonged, and the manufacturing cost is reduced. The main points of the technical scheme of the invention are as follows: a core die (1) is composed of a semielliptic left core die (2) and a semielliptic right core die (3), the part of the left core die (2), which is jointed with the right core die (3), is provided with a concave spigot socket (5), the part of the right core die (3), which is jointed with the left core die (2), is provided with a convex spigot bar (6), and the bottom of the core die (1) is provided with an elliptic punch (4) formed by a skewed surface.

Description
[technical field]
The invention belongs to mechanical technical field of forging, especially relate to a kind of shaping core rod of annular forging piece of elliptical shape.
[background technology]
At present, big and its cross section of special technical requirement is arranged is physical dimension and all manufacturings of bigger annular class machine components of weight of rectangle for bearing load, all be that the annular forging with open die forging or ring rolls making forms after machine cut processing and Metallography and Heat Treatment.But, be its physical dimension and all manufacturings of the annular class machine components of bigger elliptical shape of weight of rectangle for bearing cross-section, generally be to be to be processed by machine cut again behind the member parison with steel plate gas cutting assembly welding, but cause reduce the service life of its machine components because the fiber of its metal inside is discontinuous.Present people's production technology of the annular forging piece of perfect elliptical shape after deliberation and progressively, be manufacturing rectangle and the annular forging piece elliptical shape that size is less for bearing cross-section, can arrange forging die on the die hammer through blocking, finish-forging progressive forming with formation qualified forging in back, outside in cutting by hydraulic test.And be the production of annular forging piece of the larger-size elliptical shape of rectangle for bearing cross-section, because can not arranging forging die more greatly, its volume forms at die hammer, production outside can not be in hydraulic test excision can only use open die forging equipment to carry out small lot batch manufacture.But, use open die forging equipment to carry out the production of the annular forging piece of elliptical shape, also there is weak point, its weak point is: the surface irregularity of the middle part cavity structure of elliptical shape on the blank, stayed more inhomogeneous chipping allowance for follow-up machined, and more inhomogeneous chipping allowance can have influence on the discontinuous of part metals fiber, can reduce the service life of its machine components, and increases its manufacturing cost.
[summary of the invention]
Task of the present invention provides a kind of core rod that the shaping of doorframe flange is used that forges.Make middle part cavity structure surperficial neat, smooth of elliptical shape on its blank, stay less uniform chipping allowance for follow-up machined, its metallic fiber is continuous, increases the service life of its machine components, reduces its manufacturing cost.
Technical scheme of the present invention is as follows:
A kind ofly forge the core rod that the shaping of doorframe flange is used, include the core 1 of elliptical shape, be characterized in: core 1 is made of the left side core 2 of half-oval shaped and the right side core 3 of half-oval shaped, right surface with right side core 3 junctions on the described left side core 2 is provided with recessed " seam " groove 5, be provided with " seam " bar 6 of projection on the described right side core 3 with the left-hand face of left side core 2 junctions, described left side core 2 and the bottom of the core 1 that constitutes of the right side core 3 of the half-oval shaped drift 4 that is provided with the elliptical shape that skewed surface constitutes by half-oval shaped.
A kind ofly forge the core rod that the shaping of doorframe flange is used, use 5 chromium manganese Mos to make.
A kind of core rod that the shaping of doorframe flange is used that forges of the present invention adopts the piecemeal combining structure, is convenient to the mobile operation use of being convenient to; " seam " bar 6 of the projection that arranges on recessed " seam " groove 5 that arranges on its described left side core 2 and the right side core 3 has the function of the mutual dislocation of preventing, causes on the blank the middle cavities inner surface of elliptical shape neat, smooth.Simultaneously, the 5 chromium manganese Mos of selecting for use heat resistant and wear resistant to decrease are made, and its service life is higher.
A kind of core rod that the shaping of doorframe flange is used that forges of the present invention, in use by manipulator with the drift 4 of the elliptical shape of core rod 1 downwards and place the place, aperture of the middle part cavity structure of elliptical shape on the blank, core rod 1 is pressed in the middle cavities of elliptical shape on the blank by the forging equipment forcing press, withdraws from getting final product subsequently by manipulator upset blank and with the right side core 3 of the left side core 2 of half-oval shaped and half-oval shaped respectively.
Beneficial effect of the present invention is as follows: owing to use technique scheme, realized making middle part cavity structure surperficial neat, smooth of elliptical shape on its blank, stay less uniform chipping allowance for follow-up machined, make its metallic fiber continuous, increased the service life and the technique effect that has reduced manufacturing cost of machine components, the present invention is simple in structure.

[specific embodiment]
The invention will be further described below in conjunction with accompanying drawing.
Embodiment 1
In Fig. 1 Fig. 2 first embodiment shown in Figure 3, a kind ofly forge the core rod that the shaping of doorframe flange is used, include the core 1 of elliptical shape, be characterized in: core 1 is made of the left side core 2 of half-oval shaped and the right side core 3 of half-oval shaped, right surface with right side core 3 junctions on the described left side core 2 is provided with recessed " seam " groove 5, be provided with " seam " bar 6 of projection on the described right side core 3 with the left-hand face of left side core 2 junctions, described left side core 2 and the bottom of the core 1 that constitutes of the right side core 3 of the half-oval shaped drift 4 that is provided with the elliptical shape that skewed surface constitutes by half-oval shaped.
And core rod 1 uses 5 chromium manganese Mos to make.
Described core rod 1 adopts the piecemeal combining structure, is convenient to the mobile operation use of being convenient to; " seam " bar 6 of the projection that arranges on recessed " seam " groove 5 that arranges on its described left side core 2 and the right side core 3 has the function of the mutual dislocation of preventing, causes on the blank the middle cavities inner surface of elliptical shape neat, smooth.Simultaneously, the 5 chromium manganese Mos of selecting for use heat resistant and wear resistant to decrease are made, and its service life is higher.
Described a kind of core rod that the shaping of doorframe flange is used that forges, in use by manipulator with the drift 4 of the elliptical shape of core rod 1 downwards and place the place, aperture of the middle part cavity structure of elliptical shape on the blank, core rod 1 is pressed in the middle cavities of elliptical shape on the blank by the forging equipment forcing press, withdraws from getting final product subsequently by manipulator upset blank and with the right side core 3 of the left side core 2 of half-oval shaped and half-oval shaped respectively.
Present embodiment, realized making middle part cavity structure surperficial neat, smooth of elliptical shape on its blank, stayed less uniform chipping allowance for follow-up machined, made its metallic fiber continuous, increased the service life and the technique effect that has reduced manufacturing cost of machine components, simple in structure.
