Abstract
The invention discloses a forging die for a valve rod blank. The forging die comprises a forging die body (1), wherein the forging die body is formed by attaching two split die bodies (2 and 3) with the same structure; and a die cavity (4) of which the shape is similar to that of the valve rod blank is defined by the two split die bodies (2 and 3). The die has a simple and reasonable structure, and the high-quality valve rod blank can be efficiently produced.
Description
Technical field
The invention belongs to the forging mold field, relate in particular to a kind of valve rod forging mould.
Background technology
Valve rod is one of parts important in the valve, and therefore how producing rapidly high-quality valve rod also just becomes the urgent technical problem that solves of people.The blank of valve rod is the cylinder that cross-sectional sizes differs, and especially end diameter is larger.Valve rod all is to obtain the stepped blank that diameter differs from round steel drawing moulding at present; Obtain final needed valve rod by blank through machined again.Owing to the part that the valve rod end is thicker is shorter, need drawing to go out long segment distance and could obtain the valve rod blank, efficient is lower.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, the mould of the higher forging valve rod blank of a kind of efficient is provided.
For solving the problems of the technologies described above, concrete technical scheme of the present invention is as follows:
A kind of valve rod blank forging mould comprises the forging die body, and described forging die body is closed by the identical minute matched moulds part of two structures and forms, and two deciliters die bodys consist of a die cavity with the similar type of valve rod blank.
Further, the global shape of described forging die body is that both ends are short cylinder, and the middle part diameter is less than the cylinder of end.
Further, the planform of described die cavity is roughly multidiameter shape, the upper end be diameter greater than lower end diameter, length is less.
Further, described multidiameter two cylinder intersections arrange an arc transition structure.
The present invention is rational in infrastructure simple, adopts and forges the efficiently high texture valve rod blank of living to get of the thick principle of pier.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the structural representation of a die body of the present invention.
Fig. 3 is that the present invention uses view.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1,2 and 3, the present invention includes and forge die body 1, described forging die body 1 is fitted by the identical deciliter die body 2 and 3 of two structures and is formed, and two deciliters die bodys 2 and 3 consist of a die cavity 4.The structure of described die cavity 4 is multidiameter shapes, and upper end diameter is large but length is less, with the required similar type of valve rod blank.Simultaneously in the different axis body intersection of described die cavity two diameters arc structure 5 is set and carries out transition.The phenomenon that this arc transition structure 5 can avoid the valve rod blank stress that forges to concentrate.The global shape of described forging die body 1 is that two-end part is short cylinder, the middle part be diameter less than cylinder type, the cylinder cross section is less.This structure can be convenient to be fixed on two deciliters die bodys on the mould bases and two deciliters die bodys 2 and 3 are clamped.
The present invention needs red being positioned in the described die cavity 4 burnt in circular shaped steel 6 heating when concrete the use, and 7 pairs on the upper brill that is positioned at the forging machine of round steel top burns red round steel and exerts pressure and will obtain the valve rod blank identical with described die cavity shape and structure.
The present invention is simple in structure, owing to adopting forge hot, can eliminate the defectives such as cast condition that metal produces is loose by forge hot in smelting process, optimizes heterogeneous microstructure, so that blank has preferable quality, efficient that simultaneously should invention is higher.
