A kind of bulging mold for annular wave cone

Abstract

The invention relates to an expanding mold used for an annular wave cone, and belongs to the technical field of mold expanding machining. The expanding mold solves the problem that the annular wave cone is difficult to take and place in the expanding molding process due to the fact that the difference between the diameters of the two ends is large, and the technical problem that the size accuracy of an upper end opening and the size accuracy of a lower end opening of the annular wave cone in the molding process are not coincident due to the large height, and overall mold expanding machining of the annular wave cone is achieved. The expanding mold comprises an outer ring mechanism and an inner ring mechanism. The outer ring mechanism is composed of an outer ring, a supporting plate, a lower mold plate, a plurality of outwards-expanded pedals and a plurality of outer guide sliding plates, and the inner ring mechanism is composed of a mold core, an upper mold plate, a fixed plate, a first screw, a second screw, a first spring, a second spring, a plurality of inwards-expanded pedals and a plurality of inner guide sliding plates.

Description

technical field [0001] The invention belongs to the technical field of mold bulging processing, in particular to a bulging mold for a ring wave cone. Background technique [0002] The ring wave cone of an aero-engine is an annular gyratory wave prism, and its structure is as follows image 3 As shown, at present, roller rolling forming is generally used, the rolling precision is low, and the dimensional tolerance cannot be guaranteed; another common processing method is to use mold bulging processing, and the bulging mold is divided into internal expansion type, external expansion and internal expansion according to the structure There are two types of bulging molds. [0003] The internal expansion bulging mold is the most basic structure. The mold is composed of upper template, lower template, expansion flap, mold core and other components. During processing, the workpiece to be processed is placed outside the expansion flap. When the equipment is pressed down, the upper T...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the present invention provides a bulging mold for the ring wave cone, which solves the difficulty in removing the ring wave cone due to the large difference in diameter at both ends during the bulging molding process. Due to the high height of the ring wave cone, the technical problem of inconsistent dimensional accuracy of the upper and lower ports during the forming process, to achieve the overall mold bulging processing of the ring wave cone
