Age forming device

Abstract

An age forming device comprises a support, a die and a jack. The support comprises a base and four pillars; the die comprises a half male die and a female die; each pillar is respectively fixed on the base; both the male die and the female die are arranged on each pillar in a sleeving manner, and the male die is mounted on a male die mounting surface of each pillar; and the female die is located above the male die. The jack is mounted on the upper surface of the base. The corresponding surfaces of the male die and the female die are both molded surfaces the same as a test piece molded surface; and the molded surface of the male die is matched with the molded surface of the female die. A groove used for placing a T-shaped test piece rib is formed in the center of the length direction of the convex molded surface. The age forming device can be used for bending flat test pieces and T-shaped test pieces of various thickness, provides enough loading force and meets the forming requirement; and since the age forming device has simple structure and small volume, forming requirement of a hot pressing tank can be satisfied and meanwhile the age forming device can be applied to a drying box and a drying heater so as to have better economical efficiency.

Description

technical field [0001] The invention relates to the field of sheet metal forming, and is an aging forming device for thick plates and T-shaped parts. Background technique [0002] Age Forming (Age Forming), usually called aging stress relaxation forming in China, and creep age forming (Creep Age-forming, CAF) in foreign countries. [0003] A typical aging forming process mainly uses the stress relaxation effect of alloy materials at high temperature to cause a certain initial deformation of the workpiece, and maintains the deformation of the workpiece through an external load. After standing at a constant temperature for a period of time, the stress level of the material increases with time. And reduce, part of the elastic strain into plastic strain, so as to achieve the purpose of forming. [0004] Aluminum heat treatment aging forming generally refers to single-stage aging, but the inhomogeneity of the microstructure of single-stage aging has a strong adverse effect on me...
