Problems solved by technology

However, the pressurization devices of many rubber bladder forming dies cannot meet the complex shape requirements of aircraft sheet metal parts, and can only slightly reduce the springback of the parts. For example, the nominal pressure of the rubber bladder is generally around 60MPa, and the rubber bladder forms corner steps. The required pressure often needs to be 120~150MPa, so a lot of manual correction is required after forming

Embodiment

[0013] The rubber bag auxiliary forming mold of the present embodiment is as figure 1 Shown, comprise base plate 1 and be arranged on the molded tire 2 on the base plate 1, be positioned at the both sides of molded tire 2 on the base plate 1 and be installed with fixed pressurization block 3, be provided with and can be arranged between fixed pressurized block 3 and molded tire 2 The sunken booster block 4 sliding along the fixed booster block 3, the shape of the side of the sunken booster block 4 close to the mold tire 2 is consistent with the shape of the blank to be formed; when the blank is formed, the sunken booster block 4 is pressed The pressure falls along the inner side of the fixed pressurized block 3, and the extruded blank moves to the outer contour surface of the molded tire 2.

[0014] When in use, the rubber bladder hydraulic press presses the sunken pressurized block 4 to increase the local forming pressure between the sunken pressurized block 4 and the molded ...

Abstract

The invention relates to a rubber bag auxiliary forming die. The rubber bag auxiliary forming die comprises a base plate and a die tire arranged on the base plate. Fixed pressurization blocks are installed on two sides of the die tire on the base plate, recessed pressurization blocks capable of sliding along the fixed pressurization blocks are arranged between the fixed pressurization blocks and the die tire, and the shape of one side of every recessed pressurization block close to the die tire corresponds to the shape of the a blank part needing forming. The blank part is formed, and the recessed pressurization blocks are pressed to fall along the inner sides of the fixed pressurization blocks and extrude the blank part to move towards the outer contour surface of the die tire. The die can reduce material springback of the metal plate blank part after a rubber bag is formed, and a manual correction workload of the metal plate blank part can be greatly reduced after the rubber bag is formed.

Description

technical field [0001] The invention relates to a rubber bag auxiliary forming die, which belongs to the technical field of dies. Background technique [0002] Rubber bag forming is a kind of soft mold punch (or die) that uses a rubber bag as an elastic die (or punch) and uses liquid as a pressure transmission medium to form a metal sheet with a rigid punch (or die). Forming method, widely used in aircraft and automobile manufacturing and other fields. Rubber bag forming is half mold forming, which has the characteristics of simplifying the mold, shortening the production cycle and reducing the manufacturing cost. [0003] However, the metal material is always accompanied by elastic deformation during the rubber bag forming process, and the rebound of the metal directly affects the accuracy of the part. In the aviation manufacturing industry, the requirements for the theoretical shape of the parts are very strict. With the development of the modern aircraft manufacturing i...
