Abstract
The utility model relates to a kind of pipe die forging, and described pipe die forging is a hollow shaft, and one end is female end, the other end is socket end, the cylindrical of described female end contains the flange of the conical surface with one, the cylindrical of described socket end is with a step, and the endoporus of described pipe die forging is bellmouth.This novel described pipe die forging decreases forge weight about 20%, saves material, and forging fiber continuity, cleanliness are good, can improve service life while raising pipe die serviceability; Reduce postorder amount of machining, save man-hour.
Description
Technical field
The utility model relates to cast tube production technical field, particularly relates to a kind of pipe die forging.
Background technology
Pipe die is the critical component on centrifugal tube casting machine, work under bad environment, requires higher to product quality.
At present, existing pipe die forging, the forging surplus of its center outer surface and inner hole part is comparatively large, and the part forging fiber of pipe die female end and socket end is easily destroyed in machining process, produces adverse influence to part quality.This forging structure makes forge weight comparatively large, and forging fiber continuity is bad, and postorder amount of machining is larger.
Utility model content
In view of above-mentioned analysis, the utility model aims to provide a kind of pipe die forging, in order to solve existing pipe die forging Problems existing.
The purpose of this utility model is mainly achieved through the following technical solutions:
The utility model provides a kind of pipe die forging, and described pipe die forging is a hollow shaft, and one end is female end, and the other end is socket end, and the cylindrical of described female end contains the flange of the conical surface with one, the cylindrical of described socket end is with a step; The endoporus of described pipe die forging is bellmouth, and on described endoporus, long conical surface female end diameter is large, and socket end diameter is little.
Further, described female end is female port, connects the socket of next parts, comprises the bellmouth transition region that end step and the conical surface and segmental arc form.
Further, described socket end is convex port.
Further, on described endoporus, 1:45 ~ 1:55 got by the tapering of the long conical surface.
Further, the diameter difference at described pipe die forging step place is greater than 50mm, and length of bench is greater than 200mm.
Further, the fiber flow direction of described pipe die forging distributes along part shape, near-net-shape.
The utility model beneficial effect is as follows:
This novel described pipe die forging decreases forge weight about 20%, saves material, and forging fiber continuity, cleanliness are good, can improve service life while raising pipe die serviceability; Reduce postorder amount of machining, save man-hour.
Other feature and advantage of the present utility model will be set forth in the following description, and, becoming apparent from description of part, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in write description, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Fig. 1 is the generalized section of pipe die forging described in the utility model.
Detailed description of the invention
Specifically describe preferred embodiment of the present utility model below in conjunction with accompanying drawing, wherein, accompanying drawing forms the application's part, and is used from embodiment one of the present utility model and explains principle of the present utility model.
As shown in Figure 1, Fig. 1 is the generalized section of described forging, for the ease of understanding the shape of part and checking the actual surplus after forging, in forging drawing, draws part drawing (as shown in phantom in FIG.) with imaginary line.This pipe die forging mainly comprises: female end 1, socket end 2 and mid portion.Wherein, female end 1 is female port, connects the socket of next parts, comprises the bellmouth transition region that end step and the conical surface and segmental arc form, and socket end 2 is convex port.This pipe die forging is a hollow shaft, and the cylindrical of its female end 1 contains the flange of the conical surface with one, the cylindrical of described socket end 2 is with a step, and the endoporus of described pipe forging die block is bellmouth.When flat-die forging conditions permit, in part outer surface and endoporus, the step of diameter difference (in accompanying drawing d1-d2) >=50mm represents (as socket end outer surface step) with the step of diameter difference >=50mm, length L >=200mm on forging; Foundation part shape can be swaged into the conical surface, and forging embodies with the conical surface.
Compared with existing forging structure, in accompanying drawing 1, forging outer surface part adds step and the conical surface, forging socket end is increased a step, and female end outer surface is designed to the flange being with the conical surface, so more presses close to part shape, and can reduce forging surplus; Forging bore section is the conical surface that a tapering is larger at female end, and socket end length is short, is designed to straight tube face, and middle part is beneficial to be shaped to attach the long conical surface deviate from, and tapering is got flat-die forging plug tapering and got 1:45 ~ 1:55.Forging female end like this and middle part hole size just do not limit by part socket end minimum diameter, and pipe die mid portion length dimension is large, can greatly reduce surplus, reduces forge weight.
In sum, the utility model embodiment provides a kind of pipe die forging, and this pipe die forging structure is closer to part shape compared with existing pipe die forging structure, and fiber flow direction distributes along part shape, decrease the destruction of forging fiber in machined, achieve the near-net-shape of forging.This pipe die forging structure has the following advantages: (1) decreases forge weight about 20%, saves material (2) forging fiber continuity, cleanliness is good, can improve service life while raising pipe die serviceability; (3) reduce postorder amount of machining, save man-hour.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
