Abstract
The invention discloses a shaping die for a long shaft type forge piece, which is characterized by comprising an upper die and a lower die, wherein the upper die is provided with a concave clamping groove, the lower die is provided with a convex clamping groove, and the upper die is connected with the lower die through the clamping groove; the upper end of the upper die is provided with a concave cavity with the same shape as the head part of the long shaft type forging, and the lower end of the upper die is provided with a through hole with the same shape as the long shaft part of the long shaft type forging; the upper end of the lower die is provided with a through hole with the same shape as the long shaft part of the long shaft type forge piece, and the lower end of the lower die is provided with a larger concave cavity. The method can better correct the condition that the head and the rod of the long-shaft forging deviate from the axis seriously. The shaping method is mainly used for shaping long-shaft forgings.
Description
Technical Field
The invention relates to a shaping die, in particular to a shaping die for a long shaft type forging.
Background
The long-shaft forging is a common part on an aeroengine, and takes a low-pressure turbine shaft forging as an example, the forging has a complex structure and has the characteristics of large length-diameter ratio, thin wall, variable cross section and the like. In the process of forming the forgings, the situation that the head and the rod are seriously deviated from the axis often occurs.
SUMMERY OF THE UTILITY MODEL
The invention aims to provide a shaping die for a long-shaft forge piece, which is used for correcting the condition that a head part and a rod part are seriously deviated from an axis in the forging process.
In order to solve the technical problem, the shaping die for the long-shaft forge piece is characterized by comprising an upper die and a lower die, wherein the upper die is provided with a concave clamping groove, the lower die is provided with a convex clamping groove, and the upper die is connected with the lower die through the clamping groove; the upper end of the upper die is provided with a concave cavity with the same shape as the head part of the long shaft type forging, and the lower end of the upper die is provided with a through hole with the same shape as the long shaft part of the long shaft type forging; the upper end of the lower die is provided with a through hole with the same shape as the long shaft part of the long shaft type forge piece, and the lower end of the lower die is provided with a larger concave cavity.
Compared with the prior art, the invention has the following beneficial effects:
the shaping die for the long shaft type forge piece can better correct the condition that the head part and the rod part of the long shaft type forge piece are seriously deviated from the axis.
Drawings
The invention is described in further detail below with reference to the figures and the embodiments.
FIG. 1 is a schematic structural view of a shaping die of a long shaft forging of the invention.
FIG. 2 is an effect diagram of the shaping mold of the long shaft forging of the invention at the beginning of shape correction.
FIG. 3 is an effect diagram of the shaping die of the long shaft forging of the invention at the end of shape correction.
Detailed Description
The shaping die for the long shaft type forge piece is characterized by comprising an upper die 1 and a lower die 2, wherein as shown in figure 1, the upper die 1 is provided with a concave clamping groove, the lower die 2 is provided with a convex clamping groove, and the upper die 1 is connected with the lower die 2 through the clamping groove; the upper end of the upper die 1 is provided with a concave cavity with the same shape as the head of the long shaft type forge piece, and the lower end is provided with a through hole with the same shape as the long shaft part of the long shaft type forge piece; the upper end of the lower die 2 is provided with a through hole with the same shape as the long shaft part of the long shaft type forge piece, and the lower end of the lower die 2 is provided with a larger concave cavity.
The long-shaft forging 3 is placed into a shaping die, and as shown in fig. 2, the head of the long-shaft forging 3 is not completely attached to the concave cavity of the upper die 1; when the shape correction is finished, as shown in fig. 3, the head of the long-axis forging 3 is completely attached to the concave cavity of the upper die 1.
